Background: Exposure to high altitude increases the risk of myocardial ischemia (MI) and subsequent cardiovascular death. Nomogram is a graphical regression model, but there are no reports on using nomogram to predict myocardial ischemia under high altitude exposure. Our goal was to establish prediction models based on pre-high-altitude physical exposure examination data and identify key risk factors., Methods: We prospectively enrolled a total of 2,855 healthy individuals who underwent physical examination at the 920th Hospital of Joint Logistics Support Force and were scheduled to undergo high-altitude (3000-3500 m) training within six months. These participants were randomly divided into a training cohort (75%) and a validation cohort (25%). In the training set, single-factor analysis of variance and Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis were used to select variables, and two nomograms were established based on clinical features (CF) and clinical features + blood tests (CF + BT), respectively. The performance of the nomograms was evaluated using the area under the receiver operating characteristic curve (ROC), the concordance index (C-index), and calibration curves., Results: The C-index for the prediction models CF and CF + BT were 0.652 and 0.804, respectively. In the training cohort, the AUC for prediction models CF and CF + BT were 0.61 and 0.80, respectively. In the validation cohort, the AUC for prediction models CF and CF + BT were 0.61 and 0.81, respectively., Conclusion: We have successfully established two nomogram models to predict myocardial ischemia under high-altitude exposure and identified some risk factors., Competing Interests: Declarations.

Background: The effect of milk on the risk of ischemic heart disease (IHD) and acute myocardial infarction (MI) is unclear. We aimed to examine the association between non-fermented and fermented milk consumption on these endpoints and investigate the relationship between milk intake and cardiometabolic-related proteins in plasma., Methods: Our study is based on two Swedish prospective cohort studies that included 59,998 women and 40,777 men without IHD or cancer at baseline who provided repeated measures of diet and lifestyle factors and plasma proteomics data in two subcohorts. Through registry linkage, 17,896 cases with IHD were documented during up to 33 years of follow-up, including 10,714 with MI. We used time-updated multivariable Cox regression analysis to examine non-fermented or fermented milk intake with time to IHD or MI. Using high-throughput multiplex immunoassays, 276 cardiometabolic plasma proteins were measured in two subcohorts. We applied multivariable-adjusted regression models using a discovery-replication design to examine protein associations with increasing consumption of non-fermented or fermented milk., Results: The results for non-fermented milk differed by sex (p-value for interaction = 0.01). In women, we found a pattern of successively greater risk of IHD and MI at non-fermented milk intake levels higher than 1.5 glasses/day. Compared with an intake of 0.5 glass/day (100 mL/day), non-fermented milk intake of 2 glasses/day in women conferred a multivariable-adjusted hazard ratio (HR) of 1.05 (95% CI 1.01-1.08) for IHD, an intake of 3 glasses/day an HR of 1.12 (95% CI 1.06-1.19), and an intake of 4 glasses/day an HR of 1.21 (95% CI 1.10-1.32). Findings were similar for whole, medium-fat, and low-fat milk. We did not detect higher risks of IHD with increasing milk intakes in men. Fermented milk intake was unrelated to the risk of IHD or MI in either sex. Increasing non-fermented milk intake in women was robustly associated with a higher concentration of plasma ACE2 and a lower concentration of FGF21., Conclusions: We show a positive association between high amounts of non-fermented milk intake and IHD in women but not men. We suggest metabolic pathways related to ACE2 and FGF21 potentially underlie the association., (© 2024. The Author(s).)

Background: As future cardiovascular disease mortality trends have public health implications, we aimed to project ischemic heart disease (IHD), cerebrovascular disease (CeVD), and heart failure (HF) mortality rates for adults (40-79 years)., Methods and Results: In this population-level study, we linked the yearly mortality rates (per 100 000 US residents) (2000-2019) with IHD, CeVD, or HF as the primary cause of death from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research with the midyear US population estimates (2000-2035) for adults (40-79 years). We calculated the observed age-standardized mortality rates (2000-2019) (per 100 000 residents) (aSMR) and fitted Bayesian age-period-cohort models to project aSMR for IHD, CeVD, and HF up to 2035 in the United States. Between 2019 (last year of observed data) and 2035 (last year of projected results), the US population (40-79 years) will increase by 16% and age. The IHD aSMR will reduce from 111.9 (in 2019) to 81.8 (66.7-96.9) in 2035, an effect observed for all age groups. The CeVD aSMR will remain comparable between 2019 (37.4) and 2035 (38.6 [30.7-46.5]). The HF aSMR will increase from 16.5 in 2019 to reach 30.9 (13-48.8) in 2035; such increases were observed in all age groups., Conclusions: In the United States, between 2020 and 2035, the aSMR for IHD is expected to decrease, for CeVD will remain stable, and for HF will increase substantially. These data can inform resource allocation for future public health initiatives.

Background: For aromatase inhibitor treatment (AIT) in breast cancer, there is an unresolved concern about ischaemic cardiotoxicity. We investigated the association between AIT and ischaemic cardiotoxicity in a prospective cohort of female patients with early breast cancer who received contemporary treatment in Denmark., Methods: In this prospective cohort study in Denmark, we identified postmenopausal patients of any age diagnosed with breast cancer as recorded in the nationwide Danish Breast Cancer Cooperative Group (DBCG) clinical database between Jan 1, 2009, and Dec 31, 2020, and linked them to other nationwide registries. Exclusion criteria included having a history of other primary cancer, less than 2 years of residency in Denmark, and no inclusion in a treatment protocol according to the DBCG database, including for metastatic or locally advanced breast cancer. Information on demography, hospital diagnoses, filled prescriptions, laboratory testing, and socioeconomic status were recorded. We stratified the patient cohort according to history (yes vs no) of selected cardiovascular disease defined as ischaemic heart disease, ischaemic stroke, and heart failure, and defined the primary outcome as two-point major adverse cardiovascular events (MACE; acute myocardial infarction or ischaemic stroke). We estimated cause-specific hazard ratios (HRs) according to allocation to AIT versus not in an intention-to-treat analysis using a Cox proportional hazards regression model with age as the underlying time scale, adjusting for demographic characteristics, tumour characteristics, and other anti-cancer treatments., Findings: 43 440 postmenopausal patients diagnosed with breast cancer were identified, of whom 32 635 were followed up and included in analyses. Of 29 118 postmenopausal patients with no history of selected cardiovascular disease, we observed 510 two-point MACEs among 22 135 patients allocated to AIT (incidence rate 4·3/1000 person-years of follow-up) and 170 two-point MACEs among 6983 patients not allocated to AIT (4·1/1000 person-years). The adjusted HR was 0·91 (95% CI 0·73-1·14) for patients allocated to AIT versus patients not allocated to AIT. Among 3517 patients with a history of selected cardiovascular disease, we observed 158 two-point MACEs among 2661 patients allocated to AIT (incidence rate 12·4/1000 person-years) and 50 two-point MACEs (12·1/1000 person-years) among 856 patients not allocated to AIT (adjusted HR 0·81 [95% CI 0·58-1·15])., Interpretation: Our findings do not support a clinically relevant ischaemic cardiotoxic potential of AIT in patients with early breast cancer and do not support avoiding AIT prescription in patients with early breast cancer., Funding: Bispebjerg and Frederiksberg Hospital, Kræftens Bekæmpelse, Fonden til Lægevidenskabens Fremme, Aase og Ejnar Danielsens Fond, Helsefonden, and Læge Sofus Carl Emil Friis og Hustru Olga Doris Friis' Legat., Competing Interests: Declaration of interests ML declares funding related to the present manuscript from intramural funds at Bispebjerg and Frederiksberg Hospital, Kræftens Bekæmpelse, Fonden til Lægevidenskabens Fremme, Aase og Ejnar Danielsens Fond, Helsefonden, and Læge Sofus Carl Emil Friis og Hustru Olga Doris Friis’ Legat.

The implication of Torquetenovirus (TTV) in ischemic heart disease (IHD) has not been thoroughly explored. This study investigated the association between TTV viremia, pro-inflammatory cytokines, and IHD risk in an aging population. This cross-sectional study included 900 non-IHD subjects and 86 individuals with IHD (aged 55-75 years) selected from the MARK-AGE project. Results were verified in another independent Report-Age cohort, including 94 inpatients with chronic IHD and 111 inpatients with non-IHD (aged 65-96 years). Multivariable logistic regression in the MARK-AGE cohort revealed that male sex, TTV viremia ≥4log, Cu/Zn ratio, diabetes, hypertension, and smoking were significant IHD predictors. Notably, TTV viremia ≥4log independently increased the IHD risk (odds ratio [OR]: 2.51, 95% confidence interval [CI]: 1.42-4.43), confirmed in the Report-Age cohort (OR: 4.90, 95% CI: 2.32-10.39). In a RASIG subgroup, individuals with TTV viremia ≥4 log, both with and without IHD, exhibited increased plasma pro-inflammatory cytokine levels (IFN-γ, IL-1β, IL-6, IL-10, IL-12p70, TNF-α) compared to those with TTV viremia <4 log. No significant difference in cytokine production was observed between IHD patients and non-IHD with TTV viremia ≥4 log. A positive correlation between TTV viremia and DNA methylation estimator of leukocyte telomere length was observed in Report-Age patients. Additionally, IHD Report-Age patients with TTV viremia ≥4 log displayed higher NLR and SIRI index than those with TTV viremia <4 log. In conclusion, a high TTV viremia is associated with an elevated IHD risk in the older population, potentially arising from an augmented pro-inflammatory response and immunosenescence., (© The Author(s) 2024.

Background: Prior research has linked cardiovascular diseases with higher COVID-19 mortality and worse hospital outcomes, particularly in severe heart failure. Large population-based data regarding the impact of pre-existing ischemic heart disease (IHD) on COVID-19 outcomes is not well established., Objective: To study the impact of COVID-19 infection on IHD hospital mortality and other outcomes., Methods: The study included a patient cohort from the 2020 and 2021 National Inpatient Sample (NIS) database. Propensity score matching was used to match the study cohort (COVID-19 with IHD) to controls (COVID-19 without IHD) using a 1:1 matching ratio. The outcomes analyzed were in-hospital mortality, rates of acute kidney injury (AKI), acute myocardial injury (AMI), cardiogenic shock, cardiac arrest, mechanical ventilation, tracheal intubation, pulmonary embolism (PE), ventricular tachycardia (VT), ventricular fibrillation (VF), length of stay (LOS), and total hospitalization charges., Results: A total of 2,532,652 patients met the inclusion criteria (1,199,008 females [47.3 %), predominantly Caucasian 1,456,203 (57.5 %); mean [SD] age 63, (5.4), including 29,315 (1.1 %) patients with a history of IHD. Following propensity matching, 4,772 COVID-19 patients with and without IHD were matched. IHD patients had higher rates of AMI (adjusted odds ratio (aOR) 3.75, 95 % CI 3.27-4.31, p < 0.001), cardiogenic shock (aOR 2.89, 95 % CI 1.60-5.19, p < 0.001), VT (aOR 3.26, 95 % CI 2.48-4.29, p < 0.001), and VF (aOR 2.23, 95 % CI 1.25-3.99, p < 0.001). The odds ratios of in-hospital mortality, AKI, PE, mechanical ventilation, tracheal intubation, and resource use were not significantly different., Conclusion: A history of IHD does not impact COVID-19 mortality but increases the risk of in-hospital cardiac complications., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Objectives: The objective of this study was to analyse the global, regional, and national burdens of ischaemic heart disease (IHD) in adults aged 15-49 years and its attributable risk factors from 1990 to 2019., Study Design: Epidemiological study., Methods: Data were obtained from the Global Burden of Disease (GBD) Study 2019. The estimated annual percentage change was used to evaluate temporal trends in incidence, deaths, and disability-adjusted life years (DALYs) of youth IHD. We selected IHD-associated risk factors, including five environmental/occupational factors, 16 behavioural risks, and five metabolic factors. We computed the age-standardised rates and percentage of age-standardised DALY rates attributable to these factors of youth IHD., Results: Globally, there were 2.26 million cases of incidence, 0.63 million deaths, and 30.58 million DALYs in 2019. The age-standardised incidence, death, and DALY rates decreased from 1990 to 2019, whereas the absolute number of incidences, deaths, and DALYs increased significantly. Globally, approximately 94.1% of age-standardised DALY rates from IHD in youths aged 15-49 years are attributable to risk factors listed in the GBD 2019 dataset. The leading global and regional risk factors for youth IHD in 2019 were high low-density lipoprotein cholesterol (68.9%), high systolic blood pressure (51.2%), high body mass index (33.1%), smoking (30.5%), and ambient particulate-matter pollution (25.4%)., Conclusions: The burden of IHD among young people is still heavy, and metabolic risk factors are the leading drivers of IHD. Therefore, formulating relevant policies to control and treat cardiovascular risk factors is an effective measure to reduce the IHD burden in youth., (Copyright © 2024 The Royal Society for Public Health.

Background: Acetate, a short-chain fatty acid, has gained attention for its contrasting roles, with evidence suggesting it may offer cardiovascular protection but also promote cancer, particularly those involving sex hormones. However, these influences have been scarcely assessed in epidemiological research., Objective: To investigate the relationship between acetate and ischemic heart disease (IHD), diabetes, and cancers related to sex hormones., Methods: Mendelian randomization (MR) was used to assess potential causal effects, selecting genetic variants without linkage disequilibrium (r 2 < 0.001) and with genome-wide significance for acetate ( p < 5 × 10 -8 ). These variants were applied to large genome-wide association studies (GWAS) for ischemic heart disease (IHD; up to 154,373 cases), diabetes (109,731 cases), and five sex-hormone-related cancers (breast, colorectal, prostate, ovarian, and endometrial cancers, ranging from 8679 to 122,977 cases). We employed various methods for analysis, including penalized inverse variance weighting (pIVW), inverse variance weighting, weighted mode, and weighted median., Results: This study indicates that acetate may be associated with a lower risk of ischemic heart disease (IHD), with an odds ratio (OR) of 0.62 per standard deviation (SD) increase in acetate and a 95% confidence interval (CI) of 0.39 to 0.98. Additionally, acetate was linked to a higher breast cancer risk, with an OR of 1.26 and a 95% CI ranging from 1.08 to 1.46. This association remained robust across multiple sensitivity analyses., Conclusions: Acetate, along with factors that influence its activity, may serve as possible targets for breast cancer treatment and possibly IHD, offering opportunities for new drug development.

Background: The prevalence of chronic obstructive pulmonary disease (COPD) in patients with ischemic heart disease (IHD) remains uncertain, and its association with adverse outcomes is frequently overlooked. This study aimed to estimate the prevalence of COPD, and its impact on pharmacological treatment, and clinical outcomes in patients with IHD., Methods: A systematic literature search was conducted in Web of Science, Embase, and PubMed until November 20, 2023. All studies that reported the prevalence of COPD in IHD patients were included, and a random-effects model was employed to calculate the pooled prevalence. Data on cardiovascular risk factors/comorbidities, beta-blockers (BBs) prescription, acute phase outcomes [in-hospital mortality, major adverse cardiovascular events (MACE), acute heart failure (AHF), and cardiogenic shock], and long-term mortality were compared according to COPD status., Results: A total of 82 eligible studies that reported the prevalence of COPD in 18 million IHD patients were included. The pooled prevalence of COPD was 12.0% [95% confidence intervals (CI): 9.9%-14.1%] in patients with IHD. In subgroup analysis, the prevalence of COPD was highest in North America (15.3%), followed by Europe (10.0%), and Asia (8.8%). In addition, COPD was associated with a higher burden of cardiovascular risk factors/comorbidities, but lower BBs prescription [odds ratio (OR) 0.50, 95% CI 0.38-0.66]. Moreover, COPD was linked to an increased risk of in-hospital mortality (OR 1.47, 95% CI 1.37-1.58), MACE (OR 1.81, 95% CI 1.44-2.27), AHF (OR 2.14, 95% CI 1.86-2.46), cardiogenic shock (OR 1.30, 95% CI 1.01-1.68), as well as long-term mortality (OR 1.99, 95% CI 1.80-2.20)., Conclusion: This meta-analysis demonstrated that COPD is prevalent in IHD, involving 12.0% of IHD patients, and is linked to a lower prescription of BBs, an increased burden of comorbidities, and worse acute phase outcomes and long-term mortality., Competing Interests: The authors report no conflicts of interest in this work., (© 2024 Meng et al.)

Background: Acute coronary syndrome and atrial fibrillation are common cardiovascular diseases in elderly individuals. Patients with comorbidities face increased risks of bleeding and ischemia; however, there is a lack of prognostic models for quantifying these risks in this special population., Methods and Results: In this retrospective cohort study, 1851 patients (≥65 years old) with acute coronary syndrome and atrial fibrillation from 2 hospitals in China were included in the development cohort (1252 individuals) and 2 external validation cohorts (284 and 315 individuals). During 1-year follow-up, 96 Bleeding Academic Research Consortium type 3 or 5 bleeding events and 245 thromboembolic events were observed. In the development cohort, the concordance indexes for bleeding at 3, 6, and 12 mo ranged from 0.737 to 0.845 and for ischemia ranged from 0.723 to 0.777. The calibration curve and decision curve analysis indicated adequate calibration and clinical practicability. The concordance indexes varied from 0.679 to 0.809 in the validation cohorts. Subgroup analyses focusing on anticoagulant drugs and antithrombotic therapy were conducted, revealing similar discrimination and calibration. Kaplan-Meier curves demonstrated significant differences (log-rank P <0.001). Additionally, the models outperformed conventional models in concordance indexes, integrated discrimination improvement, and net reclassification improvement., Conclusions: Our study provides 2 robust prognostic models with easily available clinical factors for predicting bleeding and ischemia in elderly patients with acute coronary syndrome and atrial fibrillation. Furthermore, we provide online calculators to facilitate individualized risk evaluation and clinical decision-making., Registration: URL: www.chictr.org.cn/. Unique Identifier: ChiCTR2200067185.

Background: Chronic kidney disease (CKD) poses significant health risks due to its asymptomatic nature in early stages and its association with increased cardiovascular and kidney events. Early detection and management are critical for improving outcomes., Objective: This study aimed to develop and validate a prediction model for hospitalization for ischemic heart disease (IHD) or cerebrovascular disease (CVD) and major kidney events in Japanese individuals with mild CKD using readily available health check and prescription data., Methods: A retrospective cohort study was conducted using data from approximately 850,000 individuals in the PREVENT Inc. database, collected between April 2013 and April 2023. Cox proportional hazard regression models were utilized to derive and validate risk scores for hospitalization for IHD/CVD and major kidney events, incorporating traditional risk factors and CKD-specific variables. Model performance was assessed using the concordance index (c-index) and 5-fold cross-validation., Results: A total of 40,351 individuals were included. Key predictors included age, sex, diabetes, hypertension, and lipid levels for hospitalization for IHD/CVD and major kidney events. Age significantly increased the risk score for both hospitalization for IHD/CVD and major kidney events. The baseline 5-year survival rates are 0.99 for hospitalization for IHD/CVD and major kidney events are 0.99. The developed risk models demonstrated predictive ability, with mean c-indexes of 0.75 for hospitalization for IHD/CVD and 0.69 for major kidney events., Conclusions: This prediction model offers a practical tool for early identification of Japanese individuals with mild CKD at risk for hospitalization for IHD/CVD and major kidney events, facilitating timely interventions to improve patient outcomes and reduce healthcare costs. The models stratified patients into risk categories, enabling identification of those at higher risk for adverse events. Further clinical validation is required., (© 2024. The Author(s).)

Myocardial ischemia (MI) in children living with sickle cell anemia (SCA) is rarely reported. MI among children living with this disease could portend untoward outcomes on their quality of life and survival. This study evaluated the prevalence and associated risk factors of MI in children living with SCA during a vaso-occlusive crisis (VOC) compared with those with SCA who had no symptoms nor an MI in the past (those in "steady state") in Lagos, Nigeria. This comparative cross-sectional study was conducted over 10 months (between March and December 2019) among 250 children living with SCA aged 6 months-18 years (125 in VOC and 125 age and sex-matched controls in steady state). The assessment of MI was determined by measuring cardiac troponin T (cTnT) and electrocardiography (ECG). The prevalence of MI measuring cTnT alone in children with SCA during VOC and steady state was 42.4% and 23.2%, respectively. Comparatively, measuring ECG alone, the prevalence of MI in VOC and steady state was 40.8% and 20.8%, respectively. The prevalence of MI measuring cTnT and ECG in children with SCA in VOC and steady state was 38.4% and 20%, respectively. Older age, severity of pain, longer duration of illness, frequent crises per year, elevated white blood cells, and platelet count were significantly associated with MI in participants with SCA. However, with multivariate analysis, age, severity of pain, and elevated platelet counts remained significantly associated with the occurrence of MI. This study affirms the high prevalence of MI in children with SCA irrespective of the diagnostic criteria. Routine evaluation should be done in this cohort to avert MI-associated sequelae., (© The Author(s) [2024]. Published by Oxford University Press. All rights reserved.

Background: It is known that the risk of ischemic heart disease increases in patients with type 2 diabetes mellitus (T2DM). For female patients, the incidence of heart disease can be even greater after menopause, accompanied by dramatic changes in sex hormones. We investigated the correlations between sex hormones and markers of ischemic heart diseases in postmenopausal females with T2DM patients., Methods: This cross-sectional study collected data from 324 hospitalized postmenopausal females with T2DM. Multiple linear regression analyses were conducted to determine the correlations between sex hormones and cardiac markers including high-sensitive cardiac troponin T (hs-cTnT) and N-terminal prohormone of brain natriuretic peptide (NT-proBNP) levels., Results: Multiple linear regression analyses revealed that luteinizing hormone (LH) was positively and independently associated with hs-cTnT concentrations in postmenopausal females with T2DM (β = 0.189, p = 0.002). Postmenopausal females with T2DM and subclinical myocardial injury had higher LH levels than those without subclinical myocardial injury (29.67 vs. 25.08 mIU/mL, p < 0.001). A multivariate logistic regression analysis confirmed an independent and significant association between elevated LH and subclinical myocardial injury in postmenopausal females with T2DM (adjusted odds ratio [OR] = 1.077, 95% confidence interval [CI], 1.033-1.124; p < 0.001). As another gonadotropin, the follicle-stimulating hormone did not show independent correlations with hs-cTnT or NT-proBNP (p > 0.05). Neither estrogen nor testosterone was correlated with cardiac markers., Conclusions: Elevated LH levels were positively and independently associated with increased hs-cTnT levels in postmenopausal women with T2DM. Our findings suggest that LH could serve as a potential marker for assessing the risk of subclinical myocardial injury in postmenopausal females with T2DM., (© 2024 The Author(s).

Objectives: To determine the level of health-related quality of life among patients treated for ischaemic heart disease in two public-sector tertiary care settings., Methods: The analytical cross-sectional study was conducted from July to September 2021 at two tertiary care hospitals in Karachi after approval from the ethics review boards of the National Institute of Cardiovascular Diseases and the Dow University of Health Sciences, and comprised patients of either gender treated for ischaemic heart disease after being diagnosed within the preceding year who were coming for follow-up in the outpatient department. Data was collected using the short version of the World Health Organisation quality of life tool. Association of socio-demographic and clinical variables with health-related quality of life was explored. Data was analysed using SPSS 21., Results: Of the 300 patients aged 25-85 years, 212(70.7%) were males and 88(29.3%) were females. The mean total quality of life score was 6.1+/-1.4, while mean general health was 52.6+/-10.5. The lowest score among quality of life subscales was for environmental 44.7+/-15.1, while the highest score was for psychological 60.1+/-10.7 domains. Quality of life was significantly associated with patients' age, education, comorbidities, marital status, monthly income, body mass index, activities of daily living and smoking status (p<0.05)., Conclusions: ischaemic heart disease patients had average health-related quality of life in all domains, but showed low quality of life in the environmental domain.

Background and Aims: We tested the association of polygenic risk scores (PRS) for low-density lipoprotein cholesterol (LDL-C) and coronary artery disease (CAD) with LDL-C and risk of ischemic heart disease (IHD) in the Danish general population., Methods: We included a total of 21,485 individuals from the Copenhagen General Population Study and Copenhagen City Heart Study. For everyone, LDL-PRS and CAD-PRS were calculated, each based on >400,000 variants. We also genotyped four rare variants in LDLR or APOB known to cause familial hypercholesterolemia (FH)., Results: Heterozygous carriers of FH-causing variants in APOB or LDLR had a mean LDL-C of 5.40 and 6.09 mmol/L, respectively, and an odds ratio for IHD of 2.27 (95 % CI 1.43-3.51) when compared to non-carriers. The LDL-PRS explained 13.8 % of the total variation in LDL-C in the cohort. Individuals in the lowest and highest 1 % of LDL-PRS had a mean LDL-C of 2.49 and 4.75 mmol/L, respectively. Compared to those in the middle 20-80 %, those in the lowest and highest 1 % of LDL-PRS had odds ratios for IHD of 0.58 (95 % CI, 0.38-0.88) and 1.83 (95 % CI, 1.33-2.53). The corresponding odds ratios for CAD-PRS were 0.61 (95 % CI, 0.41-0.92) and 2.06 (95 % CI, 1.49-2.85)., Conclusions: The top 1 % of LDL-PRS and CAD-PRS conferred effects on LDL-C and risk of IHD comparable to those seen for carriers of rare FH-causing variants in APOB or LDLR. These results highlight the potential value of implementing such PRS clinically., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: Multimorbidity frequently occurs in patients with acute heart failure (AHF). The co-occurrence of comorbidities often follows specific patterns., Objectives: This study investigated multimorbidity subtypes and their associations with clinical outcomes., Methods: From the prospective RELAX-AHF-2 (Relaxin for the Treatment of Acute Heart Failure-2) trial, 6,545 patients (26% with HF with preserved ejection fraction, defined as LVEF ≥50%) were classified into multimorbidity groups using latent class analysis. The association between subgroups and clinical outcomes was examined. Validation of these findings was conducted in the RELAX-AHF trial, which comprised 1,161 patients., Results: Five distinct multimorbidity groups emerged: 1) diabetes and chronic kidney disease (CKD) (often male, high prevalence of CKD and diabetes mellitus); 2) ischemic (ischemic HF); 3) elderly/atrial fibrillation (AF) (oldest, high prevalence of AF); 4) metabolic (obese, hypertensive, more often HF with preserved ejection fraction); and 5) young (fewest comorbidities). After adjusting for confounders, patients in the diabetes and CKD (HR: 1.80; 95% CI: 1.50-2.20), elderly/AF (HR: 1.42; 95% CI: 1.20-1.70), and metabolic (HR: 1.40; 95% CI: 1.20-1.80) groups had higher rates of the composite outcome than patients in the young group, primarily driven by differences in rehospitalization. Treatment allocation (placebo or serelaxin) modified these associations (P interaction  <0.001). Serelaxin-treated patients in the young group were associated with a lower risk for all-cause mortality (HR: 0.59; 95% CI: 0.40-0.90). Similarly, patients from the RELAX-AHF trial clustered in 5 multimorbidity groups. The clinical characteristics and associations with outcomes could also be validated., Conclusions: Comorbidities naturally clustered into 5 mutually exclusive groups in RELAX-AHF-2, showing variations in clinical outcomes. These data emphasize that the specific combination of comorbidities can influence adverse outcomes and treatment responses in patients with AHF., Competing Interests: Funding Support and Author Disclosures This study was funded by the PROMINENT project (funding from the European Union’s Horizon 2020 research and innovation program under the Marie Skłodowska-Curie grant agreement number 754425).

Climate change and air pollution are major challenges facing the world today. Cold waves and air pollution significantly impact ischemic heart disease (IHD), but the extent of these effects at different altitudes remains unclear, especially their interactions. We collected daily meteorological, pollutant, and IHD hospitalization data from Xining and Xinxiang from 2016 to 2021. Using a time-stratified case-crossover approach, we fitted conditional Poisson regression models to assess the association between cold waves, PM 2.5 , and IHD hospitalizations and quantified their interactions. Additionally, we calculated the attributable fraction (AF) and attributable number (AN) of hospitalizations due to exposure to cold waves and medium to high-level PM 2.5 . We also performed stratified analyses by altitude, gender, and age. Both cold waves and PM 2.5 were positively associated with IHD hospitalization rates in Xining and Xinxiang, but the differences between the two regions were not significant. The relative risk of cold waves was 1.15 (1.07, 1.24) in Xining and 1.16 (1.11, 1.21) in Xinxiang. In Xining, there was an interaction between cold waves and different levels of PM 2.5 . We estimated the attributable fraction due to the joint exposure of cold waves and PM 2.5 to be 0.14-0.49 in Xining and 0.26-0.36 in Xinxiang. Older adults and males faced higher risks. This study highlights the importance of reducing PM 2.5 exposure and optimizing extreme weather warning systems and suggests further exploration of the impacts of individual behaviors and regional characteristics on IHD., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: Left ventricular (LV) thrombus is not common but poses significant risks of embolic stroke or systemic embolism. However, the distinction in embolic risk between nonischemic cardiomyopathy (NICM) and ischemic cardiomyopathy (ICM) remains unclear., Methods and Results: In total, 2738 LV thrombus patients from the JROAD-DPC (Japanese Registry of All Cardiac and Vascular Diseases Diagnosis Procedure Combination) database were included. Among these patients, 1037 patients were analyzed, with 826 (79.7%) having ICM and 211 with NICM (20.3%). Within the NICM group, the distribution was as follows: dilated cardiomyopathy (DCM; 41.2%), takotsubo cardiomyopathy (27.0%), hypertrophic cardiomyopathy (18.0%), and other causes (13.8%). The primary outcome was a composite of embolic stroke or systemic embolism (SSE) during hospitalization. The ICM and NICM groups showed no significant difference in the primary outcome (5.8% vs. 7.6%, p = 0.34). Among NICM, SSE occurred in 12.6% of patients with DCM, 7.0% with takotsubo cardiomyopathy, and 2.6% with hypertrophic cardiomyopathy. Multivariate logistic regression analysis for SSE revealed an odds ratio of 1.4 (95% confidence interval [CI], 0.7-2.7, p = 0.37) for NICM compared to ICM. However, DCM exhibited a higher adjusted odds ratio for SSE compared to ICM (2.6, 95% CI 1.2-6.0, p = 0.022)., Conclusions: This nationwide shows comparable rates of embolic events between ICM and NICM in LV thrombus patients, with DCM posing a greater risk of SSE than ICM. The findings emphasize the importance of assessing the specific cause of heart disease in NICM, within LV thrombus management strategies., Competing Interests: Declaration of competing interest Masashi Fujino has supported by the grant from the Bristol-Myers Squibb KK and the Japan Heart Foundation.

Aim: Ischemic heart disease (IHD) represents a major cardiovascular condition heavily influenced by dietary factors. This study endeavors to assess the global, regional, and temporal impact of low-fiber diets on the burden of IHD., Method: Leveraging data from the Global Burden of Disease (GBD) 2019 study, we analyzed the worldwide burden of IHD resulting from diet low in fiber using indices including death and disability-adjusted life years (DALY). This burden was further segmented based on variables including regions and countries. To track the evolution from 1990 to 2019, we utilized the Joinpoint regression model to estimate the temporal trend of IHD burden stemming from low-fiber diets., Results: In 2019, a total of 348.85 thousand (95%UI: 147.57, 568.31) deaths and 7942.96 thousand (95%UI: 3373.58,12978.29) DALY (95% UI: 707.88, 1818) of IHD were attributed to diet low in fiber globally. These figures correspond to 3.82% of all IHD deaths and 4.36% of total IHD DALYs. The age-standardized death and DALY rates per 100,000 individuals were 4.48 (95% UI: 1.90,7.27) and 97.4(95%UI: 41.44, 158.88) respectively. However, significant regional disparities emerged in these age-standardized rates, with South Asia and Central Asia experiencing the highest rates. Between 1990 and 2019, we observed that most regions displayed a downward trend of the age-standardized DALY and death rate of IHD resulting from low-fiber diets, except for Central Sub-Saharan Africa and Southern Sub-Saharan Africa., Conclusion: Our analysis underscores the substantial toll of IHD associated with low-fiber diets, particularly considering the significant regional variations. Therefore, it is imperative to sustain efforts to implement effective measures aimed at enhancing fiber intake worldwide, particularly in countries with lower socio-demographic indices., (© 2024.

Background: The objective of this study is to evaluate the global burden of ischemic heart disease (IHD) attributable to High body mass index (HBMI) by utilizing data from Global Burden of Disease (GBD) 2019., Methods: This study utilized data from the GBD 2019 to examine the impact of HBMI on deaths and disability-adjusted life years (DALYs). The analysis focused on age-standardized rates and considered a 30-year time frame. Trends were assessed using estimated annual percentage changes (EAPCs)., Results: Since 1990, a significant global increase in IHD attributable to HBMI has been observed. This increase is particularly notable among elderly males and in regions with low-middle Socio-Demographic Index (SDI), such as Central Asia and Eastern Europe. In 2019, IHD globally resulted in 1,662,339 deaths and 41,369,773 DALYs. Despite the high age-standardized death rate (20.73 per 100,000) and DALY rate (499.41 per 100,000), a declining trend was noted. This trend is reflected by the EAPCs of -0.35 for DALYs and - 0.67 for deaths. Notably, males and middle SDI countries exhibited higher rates of IHD, whereas high SDI regions such as High-income Asia Pacific and Western Europe showed decreasing trends in IHD., Conclusion: Over the past three decades, there has been a significant increase in IHD caused by HBMI, especially in low-middle and low SDI regions. This highlights the importance of targeted interventions in addressing this issue. Notably, regions including Central Asia, Eastern Europe, North Africa, and the Middle East have been heavily affected., (© 2024. The Author(s).)

Introduction: The development of depression after myocardial infarction is associated with a 2- to 2.5-fold increased risk of all-cause mortality, cardiovascular mortality, and cardiovascular events. The objective of this study was to investigate, through a broad search of the literature, whether major depression is associated with worse psychiatric outcomes in middle-aged patients with myocardial ischemia., Methods: An extensive search for studies on the association between major depression and myocardial ischemia was conducted in the PubMed, Embase, PsycINFO, and Web of Science databases. Randomized clinical trials of middle-aged patients with myocardial ischemia and concomitant depressive symptoms were included., Results: The 14 articles included in this systematic review did not confirm an association between myocardial ischemia and depression with worse psychiatric outcomes in middle-aged patients. However, worse cardiovascular outcomes have been observed in patients with depression after myocardial infarction., Conclusions: The findings of this study suggest that major depression increases cardiovascular risk in patients after acute myocardial infarction, possibly because of a more pronounced increase in inflammatory markers., Registration: This systematic review was registered in the International Prospective Registry of Systematic Reviews (PROSPERO) under the number CRD: 511650.

Background: The occurrence of transient myocardial ischemia (TMI) is an important pathology in patients with non-ST elevation acute coronary syndrome (NSTE-ACS), yet studies are scarce regarding when TMI occurs during hospitalization, particularly in relation to invasive coronary angiography (ICA). This study examined: (1) TMI before or after ICA; (2) patient characteristics and ischemic burden by TMI group (before or after ICA); and (3) major in-hospital complications (transfer to critical care, death) and length of stay by TMI group (before or after ICA)., Methods: Secondary data analysis in hospitalized NSTE-ACS patients with TMI event(s) identified from 12-lead electrocardiographic Holter. Patient records were reviewed to assess ischemic burden [TMI time (min) ÷ hours recording duration], outcomes, and TMI timing, before or after ICA., Results: In 38 patients, 3 (8%) had TMI before and after ICA. Of the remaining 35 patients (92%), TMI occurred before ICA (16; 46%), and after ICA (9; 26%), and 10 (28%) did not have ICA. Patient characteristics, untoward outcomes, and TMI duration (minutes) did not differ by group. Ischemic burden was higher in patients with TMI after ICA (7.29 ± 8.82 min/h) compared to before ICA (2.54 ± 2.11 min/h), P = 0.039. Hospital length of stay by TMI group was 113 ± 113 (before), 226 ± 244 (after), and 85 ± 65 hours (no ICA); P = 0.172., Conclusions: Almost half of the sample had TMI before ICA; one-third had TMI but did not have ICA. Patients with TMI after an ICA had a higher ischemic burden. Future studies with larger sample sizes are needed to investigate further the short- and long-term clinical significance of TMI among NSTE-ACS patients., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background and Aims: Emerging evidence suggests an arrhythmogenic effect of Anti-Ro/SSA (anti-Ro) and anti-La/SSB (anti-La) antibodies in adults, potentially involving a subclinical intracardiac inflammatory process. Despite the established association between inflammation and ischemic heart disease (IHD), it is noteworthy that as of now no study has delved into the potential link between these antibodies and IHD. This population-based study aimed to examine the association between anti-Ro/La seropositivity and IHD in the general adult population., Methods: We conducted a retrospective study using electronic medical records from the largest health maintenance organization in Israel. Patients with positive serology for either or both anti-Ro and anti-La antibodies were included, along with matched controls. Multivariate logistic regression models were utilized to assess the odds of IHD in seropositive patients compared to controls., Results: Among 17,231 seropositive patients and 84,368 controls, the rate of IHD was significantly higher in the seropositive group (9.7 % vs. 8.1 %,OR = 1.23; 95%CI 1.14-1.31; p<0.001). The association was more pronounced in younger patients [<40 years old (OR = 3.36; 95%CI 1.66-6.82; p<0.001), 40-49 years old (OR = 1.85; 95%CI 1.26-2.73; p<0.01), 50-59 years old (OR = 1.87; 95%CI 1.55-2.26; p<0.001), 60-69 years old (OR = 1.26; 95%CI 1.11-1.42; p<0.001), ≥70 years old (OR = 1.11; 95%CI 1.03-1.20; p<0.01)], as well as in patients with fewer traditional cardiovascular risk-factors (none:OR = 1.29; 95 % CI 1.09 to 1.77; p<0.01, 1-2:OR = 1.30; 95 % CI 1.19 to 1.41; p<0.001, ≥3:OR = 1.09; 95 % CI 0.99 to 1.21; p=0.076)., Conclusions: Our study demonstrates for the first time a positive association between anti-Ro/La seropositivity and IHD in the general adult population, especially among younger individuals with fewer traditional cardiovascular risk factors., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Patients with cancer are at increased risk of ischemic heart disease (IHD). The increased risk of IHD in these patients is due to the interaction of shared risk factors, cancer type and stage, and immuno/chemotherapy and radiotherapy regimens. Management of IHD in cancer patients is challenging, due to atypical presentation, increased thrombotic and bleeding risk, and worse outcomes compared to patients without cancer. In this review, we will discuss the trends, outcomes, epidemiology and challenges in the diagnosis and treatment of IHD among cancer patients., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2024 Elsevier Inc.

Background: The prevalence of combinations of comorbidities and their associations with inpatient service utilization and readmission among patients with chronic obstructive pulmonary disease (COPD) have not been extensively examined. To address this gap in knowledge, an observational prospective study was conducted using retrospective data., Aims: To identify patterns of comorbidities linked to length of hospital stay, daily expenses, and one-year readmission., Methods: The 30 most common comorbidities were identified in patients with secondary diagnoses using the association rule mining (ARM) method. Regression models were used to examine the relationships between combinations of comorbidities and service utilization, with adjustments for covariates., Results: The five most prevalent comorbidities were pulmonary heart disease (40.99%), ischemic heart disease (38.97%), heart failure (36.77%), hypertension (34.11%), and respiratory disorders (19.12%). Most combinations of comorbidities identified by ARM showed significant associations with an extended length of stay (>13 days), increased daily expenses (>930 CNY), and reduced readmission rates. Among these combinations, glycoprotein metabolism disorder had the strongest association with prolonged length of stay (adjusted odds ratio [aOR]): 1.89, 95% confidence interval [CI]: 1.82-1.95). Conversely, the combination of other brain diseases and respiratory failure was linked to higher daily expenses (aOR: 11.34, 95% CI: 10.58-12.15), and the presence of pulmonary heart disease was associated with elevated one-year readmission rates (aOR: 1.41, 95% CI: 1.37-1.46)., Conclusion: Common combinations of comorbidities among inpatients with COPD were identified from an extensive collection of discharge medical records. Furthermore, the associations between comorbidities, inpatient service usage, and readmission rates were determined.

Background: A high intake of sugar-sweetened beverages (SSBs) is associated with the risk of several chronic diseases, including ischemic heart disease (IHD) and stroke. This study aimed to model the impact of a 20% tax on all SSBs for IHD and stroke among Brazilian adults., Methods: This was an ex-ante risk comparative study. The model applied a 20% tax on SSBs and projected the incidence, prevalence and mortality of IHD and stroke over a 20-year period (2019-39). Using data on consumption, previously published cross- and own-price elasticities of SSBs, and relative risk, we estimated changes in IHD and stroke burden., Results: Our model predicts that a 20% SSB tax may reduce new cases of IHD by ~13%, especially among women, and avert ~8% of the deaths attributable to IHD over 20 years. These results represent a decrease of 19 543 new cases and 8466 and 7274 fewer deaths in the period for men and women, respectively. Estimates of reduction in incidence, prevalence and deaths from stroke were not significant over 20 years., Conclusions: Even under conservative assumptions, our study found that a small reduction in SSB consumption led to a substantial decrease in IHD incidence and mortality in Brazil., (© The Author(s) 2024.

Background: Ischemic heart disease (IHD) is a leading cause of morbidity and mortality worldwide, requiring innovative management strategies. Traditional disease management programs often struggle to maintain patient engagement and ensure long-term adherence to lifestyle modifications and treatment plans. Mobile health (mHealth) technologies have emerged as a promising approach to address these challenges by providing continuous, personalized support and monitoring. However, the reported use and effectiveness of mHealth in the management of chronic diseases, such as IHD, have not been fully explored., Objective: The primary aim of this study was to evaluate the feasibility and initial impact of an mHealth-based disease management program on coronary risk factors, specifically focusing on low-density lipoprotein cholesterol (LDL-C) levels, in individuals with chronic IHD. This formative study assessed changes in LDL-C and other metabolic health indicators over a 6-month period to determine the initial impact of the program on promoting cardiovascular health and lifestyle modification., Methods: This study was conducted using data from 266 individuals enrolled in an mHealth-based disease management program between December 2018 and October 2022. Eligibility was based on a documented history of IHD, with participants undergoing a comprehensive cardiac risk assessment before enrollment. The program included biweekly telephone sessions, health tracking via a smartphone app, and regular progress reports to physicians. The study measured change in LDL-C levels as the primary outcome, with secondary outcomes including body weight, triglyceride levels, and other metabolic health indicators. Statistical analysis used paired 2-tailed t tests and stratified analyses to assess the impact of the program., Results: Participants experienced a significant reduction in LDL-C, with LDL-C levels decreasing from a mean of 98.82 (SD 40.92) mg/dL to 86.62 (SD 39.86) mg/dL (P<.001). The intervention was particularly effective in individuals with high baseline LDL-C levels. Additional improvements were seen in body weight and triglyceride levels, suggesting a broader impact on metabolic health. Program adherence and engagement metrics suggested high participant satisfaction and compliance., Conclusions: The results of this study suggest that the mHealth-based disease management program is feasible and has an initial positive impact on reducing LDL-C levels and improving metabolic health in individuals with chronic IHD. However, the study design does not allow for a definitive conclusion regarding whether mHealth-based disease management programs are more effective than traditional face-to-face care. Future studies are needed to further validate these findings and to examine the comparative effectiveness of these interventions in more detail., (©Takahiro Miki, Junya Yamada, Shinpei Ishida, Daisuke Sakui, Masashi Kanai, Yuta Hagiwara.

This study aimed to evaluate the superiority of anthropometric indices compared to others for predicting ischemic heart disease (IHD) or cardiometabolic risk factors. This study was a cross-sectional analysis of the Pars Cohort Study data. In total, 9229 Valashahr inhabitants aged 40-75 were included in the analysis. The area under the receiver operating characteristic curve (AUC) analyses was used to compare the predictive accuracy of four anthropometric measures, including body mass index, waist to height ratio (WHtR), waist to hip ratio (WHR), and waist circumference (WC). IHD prevalence was 10.4% in our sample. The prevalence of diabetes mellitus (DM), hypertension, dyslipidemia, and metabolic syndrome was 12.7%, 29.2%, 58.4%, and 22.3%, respectively. All anthropometric indices had poor to good accuracy in predicting IHD risk factors, with AUCs ranging between 0.580 and 0.818. WHR was the most accurate measure for predicting IHD in both genders. All indexes had a better accuracy for predicting DM, dyslipidemia, and metabolic syndrome (MetS) in males than in females. To conclude, anthropometric measures, especially WC and WHtR, are recommended for predicting metabolic syndrome in primary prevention settings. These simple indices could help physicians find those who need further evaluation for MetS., (© 2024. The Author(s).)

Background: Ischemic Heart Disease (IHD) can lead to prolonged sick leave and loss of ability to work. This study aimed to describe non-return to work (non-RTW) across three IHD subgroups at 3 and at 12 months post discharge, and explore whether baseline characteristics, and patient-reported mental and physical health were associated with work detachment., Methods: Data from the national cohort study DenHeart were used, including the patient-reported outcomes (PROs) Short-Form 12, Hospital Anxiety and Depression Scale, Edmonton Symptom Assessment Scale and HeartQoL measured at discharge and register-based follow-up at 3 and at 12 months. A total of 3873 patients with IHD ≤ 63 years old and part of the workforce prior to hospitalisation, were included in the analyses and divided into three groups: chronic IHD/stable angina, non-STEMI (non-ST-Elevation Myocardial Infarction)/unstable angina and STEMI (ST-Elevation Myocardial Infarction). A composite outcome of 'prolonged sick leave' and/or 'left the workforce' was defined as non-return to work (non-RTW). Adjusted logistic regression models were performed., Results: Overall, the frequency of non-RTW was 37.7% and 38.0% at 3 and 12 months, respectively, thus not improving with time. The largest proportion of non-RTW was found in STEMI patients, followed by non-STEMI/unstable angina and IHD/stable angina patients. Several clinical and socio-demographic factors, as well as patient-reported mental and physical health were associated with non-RTW among the subgroups., Conclusion: The findings demonstrate a need for identifying IHD patients at risk of non-RTW after discharge based on their mental and physical health and a need for initiatives to minimize unwanted non-RTW., Competing Interests: Declaration of competing interest The Author(s) declare(s) that there is no conflict of interest., (Copyright © 2024.

There is insufficient data on systemic embolic events (SSEs) in patients with ischemic left ventricular aneurysm (LVA) concerning the impact of anticoagulation therapy. In this retrospective cohort study with 1043 patients with ischemic LVA, SSEs occurred in 7.2% over 2.4 years. After adjusting for relevant factors, the use of anticoagulants was independently associated with a lower incidence of SSE (3.1% vs. 9.0%, P < 0.001; subdistribution hazard ratios (SHR) 0.21, 95% confidence intervals (CI) 0.10-0.44, P < 0.001), with no significant difference in net adverse clinical events (NACEs) (10.6% vs. 13.3%, P = 0.225). Specifically, anticoagulation in patients with apical segment akinesis significantly reduced SSEs (3.9% vs. 13.6%, P = 0.002) and NACE rates (7.8% vs. 19.4%, P = 0.002). Major bleeding rates did not significantly differ between groups (5.6% vs. 3.5%, P = 0.111). These findings highlight the SSE risk in ischemic LVA and suggest potential benefits of anticoagulation, particularly in those with apical segment akinesis. These findings need to be validated in independent datasets., (© 2024. The Author(s).)

Background: Angina with no obstructive coronary disease (ANOCA) and ischemia with no obstructive coronary disease, prevalent yet underrecognized conditions, mostly affect women. Previous studies rarely distinguished between them. We aimed to compare the prevalence of objective ischemia through various examinations in women with ANOCA and assess the impact of objective and subjective ischemia on their mental health., Methods and Results: A total of 84 eligible women with ANOCA and 42 controls underwent mental stress, pharmacological stress, exercise stress, and Holter testing. Objective evidence of myocardial ischemia was assessed by positron emission tomography-computed tomography and ECG, and subjective symptoms were graded using the Canadian Cardiovascular Society scale (CCS). Psychological assessments were conducted using 6 scales. Among 84 women with ANOCA, 37 (44%) received a diagnosis of ischemia with no obstructive coronary disease following mental stress testing, 20 (28.6%) through pharmacological stress testing, 14 (21.2%) via exercise stress testing, and 24 (32.9%) from Holter. Mental stress-induced myocardial ischemia was more prevalent ( P <0.05). Among 54 patients with ANOCA who completed all tests, 30% showed no ischemia, and only 1 (1.9%) showed ischemia in all tests. In addition, patients with ANOCA had higher psychological scores than controls ( P <0.01). No significant differences was observed in psychological scores between ANOCA with positive and negative ischemia test results ( P >0.05). However, ANOCA with milder angina (CCS I) exhibited higher scores across the Hospital Anxiety and Depression Scale, State-Trait Anxiety Inventory, Perceived Stress Scale, and Posttraumatic Stress Disorder Checklist-Civilian Version and a higher prevalence of Type D personality traits ( P <0.05)., Conclusions: In patients with ANOCA, the positive rate of myocardial ischemia exhibits variability among several noninvasive tests. A worsened psychological state is more closely linked to milder angina symptoms than to ischemia performance, highlighting the importance of focusing on symptom management in their psychological care., Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT03982901.

Objective: Despite significant advancements in understanding risk factors and treatment strategies, ischemic heart disease (IHD) remains the leading cause of mortality worldwide, particularly within specific regions in Brazil, where the disease is a burden. Therefore, the aim of this study was to estimate the risk of hospitalization and mortality from IHD in the state of Paraná (Brazil), using spatial analysis to identify areas with higher risk based on socioeconomic, demographic and health variables., Methods: This is an ecological study based on secondary and retrospective IHD hospitalization and mortality data obtained from the Brazilian Hospitalization and Mortality Information Systems during the 2010-2021 period. Data were analyzed for 399 municipalities and 22 health regions in the state of Paraná. To assess the spatial patterns of the disease and identify relative risk (RR) areas, we constructed a risk model by Bayesian inference using the R-INLA and SpatialEpi packages in R software., Results: A total of 333,229 hospitalizations and 73,221 deaths occurred in the analyzed period, and elevated RR of hospitalization (RR = 27.412, CI 21.801; 34.466) and mortality (RR = 15.673, CI 2.148; 114.319) from IHD occurred in small-sized municipalities. In addition, medium-sized municipalities also presented elevated RR of hospitalization (RR = 6.533, CI 1.748; 2.006) and mortality (RR = 6.092, CI 1.451; 2.163) from IHD. Hospitalization and mortality rates were higher in white men aged 40-59 years. A negative association was found between Municipal Performance Index (IPDM) and IHD hospitalization and mortality., Conclusion: Areas with increased risk of hospitalization and mortality from IHD were found in small and medium-sized municipalities in the state of Paraná, Brazil. These results suggest a deficit in health care attention for IHD cases in these areas, potentially due to a low distribution of health care resources., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2024 The Author(s).)

Ischemic heart disease (IHD) is a condition in which the heart is starved of oxygen. Knowing the dietary risk factors implementing appropriate nutritional interventions in this regard seems essential. Therefore, the present study was carried out to determine the epidemiological features of IHD affected by dietary risks. This study used data from the Global Burden of Disease (GBD) study. In this study, we collected information on death, years lived with disability (YLD), and disability-adjusted life years (DALYs) of IHD affected by dietary risks in one hundred thousand people with 95% confidence based on the direct Age Standard Rate (ASR). We applied these data based on the Socio-demographic Index (SDI). In 2019, the number of IHD deaths, YLDs, and DALYs attributable to dietary risks was 62.43 million (95% UI [50.97-73.63] per 100,000 population), 36.88 (95% UI [23.87-53.32] per 100,000 population), and 1271.32 (95% UI [1061.29-1473.75] per 100,000 population), respectively. We found that the lowest DALYs of IHD affected by dietary risks by ASR are for high SDI countries. Most dietary risk factors related to IHD in countries with high and high middle SDI were related to a diet high in red and processed meat, sodium, and low in legumes, but in countries with low and low middle SDI, it was related to a diet low in fiber, fruit, nuts and seeds, PUFA, seafood W3 fatty acids, vegetables and whole grain. Considering that the dietary risk factors related to IHD are different based on SDI, it is necessary to consider nutritional interventions according to SDI., (© 2024. The Author(s).)

This study aimed to compare the 2-year cardio-cerebrovascular adverse outcomes of patients with influenza with and without preexisting cardiovascular disease (preCVD) treated with oral antiviral agents in the outpatient clinic. Oral antiviral agents are routinely prescribed to treat influenza infection with a positive rapid-antigen test in the outpatient clinic; however, influenza-associated cardio-cerebrovascular outcomes have not yet been characterized in patients with preCVD treated with oral antiviral agents. Data between 2006 and 2016 were extracted from the National Health Database of South Korea. A total of 865,522 patients with influenza treated with oral antiviral agents were selected in South Korea and classified as preexisting ischemic heart disease (IHD), heart failure (HF), or atrial fibrillation (AF), and 2-year cardio-cerebrovascular outcomes were analyzed using a Cox proportional hazard regression model. Among the participants, 96,433 had preCVD (11.1%; mean age, 46 years) including IHD (86.4%), HF (23.1%), and AF (12.5%). The incidence of new-onset IHD, AF, HF, and death was similar between patients with influenza with and without preCVD. The incidences of IHD and stroke were 0.489 and 0.047 per 100-person year in the preCVD group, respectively. The incidence of cardiovascular mortality was 0.489 per 100-person year in the preCVD group, and the hazard ratio for cardiovascular mortality in the preCVD group was not significantly different from that in patients without preCVD. Based on the national health data, 2-year cardio-cerebrovascular adverse outcomes were not significantly different between patients with and without preCVD treated with oral antiviral agents., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

In many developing countries with surging vehicular traffic and inadequate traffic management, excessive road traffic noise exposure poses substantial health concerns, linked to increased stress, insomnia and other metabolic disorders. This study aims to assess the linkage between sociodemographic factors, traffic noise levels in residential areas and health effects using a cross-sectional study analyzing respondents' perceptions and reports. Noise levels were measured at 57 locations in Srinagar, India, using noise level meter. Sound PLAN software was employed to generate noise contour maps, enabling the visualization of noise monitoring locations and facilitating the assessment of noise levels along routes in proximity to residential areas. Correlation analysis showed a strong linear relationship between field-measured and modelled noise (r 2  = 0.88). Further, a questionnaire-based survey was carried out near the sampling points to evaluate the association of ischemic heart disease with traffic noise. Residents exposed to noise levels (L den  > 60 dB(A)) were found to have a 2.24 times higher odds ratio. Compared to females, males reported a 16% higher prevalence of the disease. Multi-faceted policy strategies involving noise mapping initiatives, source noise standards, traffic flow urban mobility optimization, smart city initiatives and stringent litigatory measures could significantly reduce its detrimental impact on public health. Finally, this study envisions a region-specific strong regulatory framework for integrating noise pollution mitigation strategies into the public health action plans of developing nations., (© 2024.

Objectives: This study aimed to determine the risk of ischemic heart disease (IHD) and stroke among male couriers in Korea by linking the data from the National Health Insurance (NHI) and National Employee Insurance (NEI) databases., Methods: As of 2015, the NHI and NEI databases were linked using individual IDs. A cohort of male couriers, aged between 20 and 64 years, ( N = 5,012) was constructed using the Korean Employment Insurance Occupational Classification (KECO-2007). For comparison, a cohort of male total wage workers ( N = 5,429,176) and a cohort of office workers ( N = 632,848) within the same age group were also constructed. The follow-up was conducted until 31 December 2020 to confirm the occurrence of IHD and stroke. The diagnoses were defined using the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) codes. The criteria included medical services for more than 1 day of hospitalization or more than 2 outpatient visits. The age-standardized incidence ratio (SIR) was calculated to evaluate the risk of occurrence. The hazard ratio (HR) was calculated using the Cox model after adjusting for age, alcohol consumption, smoking, obesity, income level, and employment duration as confounding variables., Results: The SIR of IHD for couriers was 1.54 (95% CI 1.31-1.78), while for office workers, it was 1.08 (95% CI 1.06-1.10), compared to male total wage workers. The SIR for stroke was higher for couriers at 1.84 (95% CI 1.40-2.28) and lower for office workers at 0.86, compared to male total wage workers. Couriers had a higher SIR for stroke at 1.84 (95% CI 1.40-2.28) and lower for office workers at 0.86 (0.83-0.89). Compared to total wage workers, couriers had a significantly higher adjusted HR for IHD at 1.60 (95% CI 1.37-1.87) and a higher HR for stroke at 1.39 (95% CI 1.07-1.79). Compared to office workers, couriers had a significantly higher HR for IHD at 1.34 (95% CI 1.13-1.59) as well as for for stroke at 1.43 (95% CI 1.08-1.88)., Conclusion: The incidence of IHD and stroke was higher among male couriers compared to male office workers and total wage workers, highlighting the need for implementing public health interventions to prevent IHD and stroke among couriers., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Yoon, Min, Kim, Kim and Kim.)

Introduction: The importance of exercise electrocardiogram (ECG) is still controversial in the prevention of cardiovascular events among sportsmen and sportswomen. The aim of this study was to assess the relevance of exercise ECG as a screening tool to prevent cardiovascular events when any cardiovascular disease (CVD) risk factors are present., Methods: The study included leisure time asymptomatic sportsmen and sportswomen over age 35 evaluated from 2011 to 2016 at the University Hospital of Saint-Etienne (France). Major adverse cardiovascular events (MACE) and atrial fibrillation were collected at 3 years., Results: Of the cohort of 2457 sportsmen and sportswomen (mean age 50.2 ± 9.4 years), 50 (2%) had a high-risk SCORE2. A total of 256 exercise ECGs (10%) were defined as positive, most of them due to silent myocardial ischemia (SMI) (n = 196; 8%). These 196 SMI cases led to 33 coronary angiograms (1%), which revealed 23 significant coronary stenoses requiring revascularization. In multivariate logistic regression analysis, having at least two CVD risk factors was independently associated with (1) positive exercise ECG (OR = 1.80 [95% CI: 1.29-2.52], p = 0.0006), with (2) suspected SMI (OR = 2.57 [95% CI: 1.10-6.02], p = 0.0304), with (3) confirmed SMI (OR = 8.20 [95% CI: 3.46-19.46], p < 0.0001) and with (4) cardiovascular events (MACE or atrial fibrillation) (OR = 6.95 [95% CI: 3.49-13.81], p < 0.0001) at 3 years (median)., Conclusions: The study supports the European recommendations for the use of exercise ECG in evaluation of asymptomatic leisure time sportsmen over age 35. Having at least two CVD risk factors was the best predictor for presence of coronary artery stenosis that may increase the risk for adverse events., Trial Registration: ClinicalTrials.gov Identifier: NCT06024863., (© 2024 John Wiley & Sons A/S.

Abstract: Ischaemia with no obstructive coronary arteries (INOCA) has been a diagnostic and therapeutic challenge for decades. Several studies have demonstrated that INOCA is associated with an increased risk of death, adverse cardiovascular events, poor quality of life and high healthcare cost. Although there is increasing recognition of this entity in the Western population, in the Asian population, INOCA remains elusive and its prevalence uncertain. Despite its prognostic significance, diagnosis of INOCA is often delayed. In this review, we identified the multiple barriers to its diagnosis and management, and proposed strategies to overcome them., (Copyright © 2024 Copyright: © 2024 Singapore Medical Journal.)

This study was intended to evaluate the pathological outcome of cardiopulmonary bypass whilst considering socio-demographic variables and surgical technique on early postoperative results following coronary artery bypass graft (CABG) surgery in patients at a tertiary level hospital in Bangladesh. This observational study evaluated a total of 880 patients with ischemic heart disease in Bangabandhu Sheikh Mujib Medical University, Bangladesh from 2011 to 2019 who were undergoing an isolated CABG surgery. In this current study, the population divided into two groups- Group A: Off-pump CABG (n=440) and Group B: On-pump CABG (n=440). The mean age of the patients was 55.25±5.0 years in off-pump and 50.75±5.2 years in the on-pump group. Risk factors, including smoking, hypertension, and hyperlipidemia, were predominant in both study groups. Total operative time was notably higher in the on-pump CABG group. However, grafting time was more in the off-pump CABG procedures. Postoperative neurological deficits were higher amongst the on-pump CABG population. The mean time of mechanical ventilation, intensive care unit (ICU) stay, total hospital stay, and mortality was notably higher in the on-pump CABG group. Moreover, the number of mortalities in on-pump CABG patients was primarily due to the low output syndrome, failure of weaning from cardiopulmonary bypass (CPB) and sudden cardiac arrest. Off-pump CABG is now more acceptable due to its potentiality to avoid CPB induced complications, aortic cannulation, and cross-clamping. Cardiac arrest in on-pump CABG induces global ischemia and reperfusion injury to the cardiac muscle. Besides, the Off-pump CABG provides a conspicuous survival advantage compared to the on-pump CABG, in association with a notable reduction in postoperative morbidity and mortality.

Background: Age-sex specific trend analyses of ischemic heart disease (IHD)-related mortality and prevalent risk factors can improve our understanding and approach to the disease., Methods: We performed a 15-year retrospective epidemiological analysis of acute and chronic IHD-related mortality and prevalent cardiovascular risk factors using administrative data from Veneto, a socio-economically homogeneous Italian region. Standard mortality statistics using the underlying cause of death (UCOD) and deaths with any mention of IHD in death certificates (MCOD) from ICD-10 codes I20-I25 was performed between 2008 and 2022., Results: A total of 134,327 death certificates reported IHD-related deaths, representing 18.6% of all deaths. Proportional mortality decreased from 14.6% in 2008 to 7.8% in 2022 for deaths with IHD as the UCOD and from 23.5% to 14.6% for deaths with IHD among the MCOD. A more pronounced decline of proportionate and case-specific mortality rate was seen in women. The decline in mortality over the whole study period was larger for acute (vs. chronic) IHD. The COVID-19 pandemic led to a marked increase in mortality in 2020 (+12.2%) with a subsequent further decline. IHD-related deaths displayed a typical seasonal pattern with more deaths during winter. The prevalence of cardiovascular risk factors was higher in IHD (vs. no IHD) deaths: this association appeared more pronounced in younger adults., Conclusions: We provided an analysis of epidemiological trends in IHD-related mortality and prevalence of risk factors. Our findings indicate a change in the pattern of cardiovascular deaths and may suggest a switch in death from acute to chronic conditions., Competing Interests: Declaration of competing interest We declare that we have no competing interests related to this work., (Copyright © 2024 The Authors.

Objectives: Overweight and obesity (OWOB) starts in childhood, influences adult cardiovascular risk, and is not equally distributed across ethnic groups. It is unclear which effects can be expected from reductions in OWOB across the life course on inequalities in cardio-metabolic diseases in a multi-ethnic population. This study aims to estimate the effects of three scenarios of changes in OWOB (the Normal-Weight-for-All scenario, the No-Ethnic-Difference-over-the-Life-Course scenario, the and No-Ethnic-Differences-in-Childhood scenario)., Study Design: A simulation study., Methods: We combine data from multiple data sources and use the Dynamic Modeling for Health Impact Assessment (DYNAMO-HIA) model to estimate the effects of three scenarios on the cumulative incidence of diabetes mellitus, ischaemic heart disease (IHD) and stroke between 18 and 70 years in the five largest ethnic groups in the Netherlands., Results: In the scenario where all individuals have normal weight, the cumulative incidence decreased in all ethnic minority groups for all diseases, with largest decreases among South-Asian Surinamese, where the reduction of diabetes incidence exceeded 50%. In the scenario where the prevalence of OWOB in each ethnic-minority group was reduced to the current level among the Dutch-origin population, ethnic inequalities in cardio-metabolic diseases were substantially reduced, particularly when lowered prevalence of OWOB persisted across the lifespan. Reductions were the largest for diabetes and for the Asian Surinamese population., Conclusions: A substantial part of the well-known ethnic inequalities in incidence of diabetes, IHD, and stroke can be attributed to OWOB. Interventions aimed at reducing OWOB have clear potential to reduce the health inequalities in these outcomes, especially for diabetes, in particular when they have an impact across the lifespan., (Copyright © 2024 The Authors.

Background and Objectives : Job strain is a psychological, physical, and behavioral stress that occurs at the workplace. Job strain is associated with more than double the normal risk of coronary artery disease (CAD). The main aim of this study was to determine the association between job strain and the following parameters: high-sensitivity C-reactive protein (hs-CRP), the albumin urine excretion rate (AUER), and secondary-level testing. Materials and Methods : This study was a descriptive cross-sectional study conducted on patients who underwent cardiological assessment between October 2023 and February 2024 at the Promedicanon Cardiology Center. This study comprised 210 participants, with two groups: 105 chronic coronary syndromes (CCS) patients and 105 no-CCS patients. The baseline characteristics collected were age, gender, education, rural/urban environment, traditional CAD risk factors, hs-CRP, and AUER. The secondary-level testing included an electrocardiogram (ECG), echocardiography, and enhanced contrast computed tomography (ECCT). Psychological questionnaires comprised the tertiary-level testing, including the PHQ-9 depression questionnaire, and the satisfaction with work scale (SWWS) for job strain (Likert score). Results : The baseline characteristics were all significantly different between the groups ( p < 0.05) except for total cholesterol. The hs-CRP level had a mean value of 0.4837 ± 0.19082 in the CCS group; for the no-CCS group, the hs-CRP mean value was 0.2289 ± 0.11009; p -value < 0.001. The AUER had a mean value of 42.770 ± 12.8658 for the CCS group and 26.432 ± 9.7338 for the no-CCS group; p -value < 0.001. For the associations between secondary-level testing and job strain: p < 0.001 for ST depression, negative T-waves, and q-waves; p = 0.415 for atrial fibrillation (AF); p = 0.018 for wall motion studies; p = 0.005 for ECCT. The association between job strain and AF had no statistical significance. The contractility of left ventricle walls and coronary calcification score were associated with job strain, with statistical significance. The p -value was 0.013 for the relationship between depression and the ECCT; for the association between depression and CCS status, the p -value was 0.021. Depression is usually diagnosed in job strain. The association between depression, and coronary calcification, as well as depression and CCS status had statistical significance. Conclusions: Job strain increased the hs-CRP level and AUER in both the CCS and no-CCS patients. The primary and secondary prevention of CHD could also include interventions to reduce job strain.

Background: Some autoimmune diseases carry elevated risk for atherosclerotic cardiovascular disease (ASCVD), yet the underlying mechanism and the influence of traditional risk factors remain unclear., Objectives: This study sought to determine whether autoimmune diseases independently correlate with coronary atherosclerosis and ASCVD risk and whether traditional cardiovascular risk factors modulate the risk., Methods: The study included 85,512 patients from the Western Denmark Heart Registry undergoing coronary computed tomography angiography. A diagnosis of 1 of 18 autoimmune diseases was assessed. Adjusted OR (aOR) for any plaque, any coronary artery calcification (CAC), CAC of >90th percentile, and obstructive coronary artery disease as well as adjusted HR (aHR) for ASCVD were calculated., Results: During 5.3 years (Q1-Q3: 2.8-8.2 years) of follow-up, 3,832 ASCVD events occurred. A total of 4,064 patients had a diagnosis of autoimmune disease, which was associated with both presence of any plaque (aOR: 1.29; 95% CI: 1.20-1.40), any CAC (aOR: 1.28; 95% CI: 1.19-1.37), and severe CAC of >90th percentile (aOR: 1.53; 95% CI: 1.39-1.68), but not with having obstructive coronary artery disease (aOR: 1.04; 95% CI: 0.91-1.17). Patients with autoimmune diseases had a 46% higher risk (aHR: 1.46; 95% CI: 1.29-1.65) for ASCVD. Traditional cardiovascular risk factors were strongly associated with future ASCVD events, and a favorable cardiovascular risk factor profile in autoimmune patients was associated with ∼54% lower risk compared to patients with presence of risk factors (aHR: 0.46; 95% CI: 0.27-0.81)., Conclusions: Autoimmune diseases were independently associated with higher burden of coronary atherosclerosis and higher risk for future ASCVD events, with risk accentuated by traditional cardiovascular risk factors. These findings suggest that autoimmune diseases increase risk through accelerated atherogenesis and that cardiovascular risk factor control is key for improving prognosis in patients with autoimmune diseases., Competing Interests: Funding Support and Author Disclosures This study was funded by Aarhus University Hospital.

In a translational study involving animal models and human subjects, Lv et al. demonstrate that arachidonic acid (AA) exhibits cardioprotective effects in diabetic myocardial ischemia, suggesting a departure from its known role in promoting ferroptosis-a form of cell death characterized by iron-dependent lipid peroxidation. However, the study does not address how underlying diabetic conditions might influence the metabolic pathways of AA, which are critical for fully understanding its impact on heart disease. Diabetes can significantly alter lipid metabolism, which in turn might affect the enzymatic processes involved in AA's metabolism, leading to different outcomes in the disease process. Further examination of the role of diabetes in modulating AA's effects could enhance the understanding of its protective mechanism in ischemic conditions. This could also lead to more targeted and effective therapeutic strategies for managing myocardial ischemia in diabetic patients, such as optimizing AA levels to prevent heart damage while avoiding exacerbating factors like ferroptosis., (© 2024.

Background: Few studies have investigated the role of social determinants of health (SDoH) in patients with atrial fibrillation (AF)., Aim: To investigate the relationship between SDoH and adverse events in a large multinational AF cohort., Design: Retrospective study utilizing a global federated health research network (TriNetX)., Methods: Patients with AF were categorized as socially deprived defined according to ICD codes based on three SDoHs: (i) extreme poverty; (ii) unemployment; and/or (iii) problems related with living alone. The outcomes were the 5-year risk of a composite outcomes of all-cause death, hospitalization, ischemic heart disease (IHD), stroke, heart failure (HF) or severe ventricular arrhythmias. Cox regression was used to compute hazard rate ratios (HRs) and 95% confidence intervals (CIs) following 1:1 propensity score matching (PSM)., Results: The study included 24 631 socially deprived (68.8 ± 16.0 years; females 51.8%) and 2 462 092 non-deprived AF patients (75.5 ± 13.1 years; females 43.8%). Before PSM, socially deprived patients had a higher risk of the composite outcome (HR 1.9, 95% CI 1.87-1.93), all-cause death (HR 1.34, 95% CI 1.28-1.39), hospitalization (HR 2.01, 95% CI 1.98-2.04), IHD (HR 1.67, 95% CI 1.64-1.70), stroke (HR 2.60, 95% CI 2.51-2.64), HF (HR 1.91, 95% CI 1.86-1.96) and severe ventricular arrhythmias (HR 1.83, 95% CI 1.76-1.90) compared to non-deprived AF patients. The PSM-based hazard ratios for the primary composite outcome were 1.54 (95% CI 1.49-1.60) for the unemployed AF patients; 1.39 (95% CI 1.31-1.47) for patients with extreme poverty or with low income; and 1.42 (95% CI 1.37-1.47) for those with problems related with living alone., Conclusions: In patients with AF, social deprivation is associated with an increased risk of death and adverse cardiac events. The presence of possible unmeasured bias associated with the retrospective design requires confirmation in future prospective studies., (© The Author(s) 2023.

Background: There is limited evidence on the prevalence of ischaemic heart disease (IHD) and its association with risk factors and socioeconomic status (SES) in low- and middle-income countries (LMICs). Given the relatively high levels of access to healthcare in Sri Lanka, the association of IHD with SES may be different from that observed in other LMICs., Objectives: To estimate the prevalence of IHD in Sri Lanka, determine its associated risk factors and its association with SES., Methods: We analysed data from 6,513 adults aged ≥18 years examined in the 2018/19 Sri Lanka Health and Ageing Study. We used the Rose angina questionnaire to classify participants as having angina (Angina+) and used self-report or medical records to identify participants with a history of IHD (History+). The association of Angina+ and History+ with age, ethnicity, sector of residence, education level, household SES wealth quintile, area SES wealth quintile, hypertension, diabetes, smoking, total cholesterol, cholesterol-to-HDL ratio, waist-to-hip ratio and body mass index were analysed in unadjusted and adjusted models. Additional analyses were performed to investigate sensitivity to correction for missing data and to benchmark estimates against evidence from other studies., Conclusions: We estimated prevalence of History+ of 3.9% (95% CI 3.3%-4.4%) and Angina+ of 3.0% (95% CI 2.4%-3.5%) in adults aged 18 years and over. The prevalence of Angina+ was higher in women than men (3.9% vs. 1.9%, p < 0.001) whilst prevalence of History+ was lower (3.8% vs. 4.0%, p = 0.8), which may suggest a higher rate of undiagnosed IHD in women. A history of IHD was strongly associated with age, hypertension and diabetes status even after adjusting for sociodemographic factors. Though the prevalence of History+ was higher in the most developed area SES tertile and urban areas, History+ was also associated with less education but not household SES, consistent with patterns emerging from other LMICs., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2024 The Author(s).)

Aims: To explore the associations between visit-to-visit lipid variability and risk of ischemic heart disease (IHD) in a population-based cohort in China., Methods: We evaluated lipid variability in 30,217 individuals from the Yinzhou Health Information System who had ≥3 recorded lipid measurements during 2010-2014. We used various indicators including standard deviation (SD), coefficient of variation (CV), variability independent of the mean (VIM), and average real variability (ARV) to quantify the variability in triglycerides, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C). We used Cox proportional hazards models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs)., Results: Overall, a total of 1305 participants with IHD were identified during the follow-up of 194,421 person-years. Subjects in Q4 had a 21% elevated risk of IHD (HR = 1.21, 95% CI: 1.03-1.41) for LDL-C variability (CV) compared with the reference (Q1). The HRs for Q4 vs Q1 were 1.21 (95% CI: 1.04-1.42) for HDL-C variability, and 1.28 (95% CI: 1.10-1.50) for TC variability. However, no association was observed between triglycerides variability and risk of IHD., Conclusions: Higher variability in LDL-C, HDL-C, and TC levels was associated with an elevated risk of IHD, suggesting that lipid variability could be considered as an independent risk factor of IHD., (© 2023.

Background: Cardiovascular disease is the leading cause of death among women in the United States. It is well established that gestational diabetes mellitus is associated with an overall lifetime increased risk of cardiometabolic disease, even among those without intercurrent type 2 diabetes. However, the association between gestational diabetes mellitus and short-term risk of cardiovascular disease is unclear. Establishing short-term risks of cardiovascular disease for patients with gestational diabetes mellitus has significant potential to inform early screening and targeted intervention strategies to reduce premature cardiovascular morbidity among women., Objective: This study aimed to compare the risk of cardiovascular disease diagnosis in the first 24 months postpartum between patients with and without gestational diabetes mellitus., Study Design: Our longitudinal population-based study included pregnant individuals with deliveries from 2007 to 2019 in the Maine Health Data Organization's All Payer Claims Database. We excluded records with gestational age <20 weeks, non-Maine residence, multifetal gestation, no insurance in the month of delivery or the 3 months before pregnancy, an implausibly short interval until next pregnancy (<60 days), pregestational diabetes mellitus, and any prepregnancy diagnosis of the cardiovascular conditions being examined postpartum. Gestational diabetes mellitus and cardiovascular disease (heart failure, ischemic heart disease, arrhythmia/cardiac arrest, cardiomyopathy, cerebrovascular disease/stroke, and new chronic hypertension) were identified by International Classification of Diseases 9/10 diagnosis codes. Cox proportional hazards models were used to estimate hazard ratios, adjusting for potential confounding factors. We assessed whether the association between gestational diabetes mellitus and chronic hypertension was mediated by intercurrent diabetes mellitus., Results: Among the 84,746 pregnancies examined, the cumulative risk of cardiovascular disease within 24 months postpartum for those with vs without gestational diabetes mellitus was 0.13% vs 0.20% for heart failure, 0.16% vs 0.14% for ischemic heart disease, 0.60% vs 0.44% for cerebrovascular disease/stroke, 0.22% vs 0.16% for arrhythmia/cardiac arrest, 0.20% vs 0.20% for cardiomyopathy, and 4.19% vs 1.83% for new chronic hypertension. After adjusting for potential confounders, those with gestational diabetes had an increased risk of new chronic hypertension (adjusted hazard ratio, 1.56; 95% confidence interval, 1.32-1.86) within the first 24 months postpartum compared with those without gestational diabetes. There was no association between gestational diabetes and ischemic heart disease (adjusted hazard ratio, 0.75; 95% confidence interval, 0.34-1.65), cerebrovascular disease/stroke (adjusted hazard ratio, 1.13; 95% confidence interval, 0.78-1.66), arrhythmia/cardiac arrest (adjusted hazard ratio, 1.16; 95% confidence interval, 0.59-2.29), or cardiomyopathy (adjusted hazard ratio, 0.75; 95% confidence interval, 0.40-1.41) within the first 24 months postpartum. Those with gestational diabetes appeared to have a decreased risk of heart failure within 24 months postpartum (adjusted hazard ratio, 0.45; 95% confidence interval, 0.21-0.98). Our mediation analyses estimated that 28% of the effect of gestational diabetes on new chronic hypertension was mediated through intercurrent diabetes mellitus., Conclusion: Patients with gestational diabetes mellitus have a significantly increased risk of new chronic hypertension as early as 24 months postpartum. Most of this effect was not due to the development of diabetes mellitus. Our findings suggest that all women with gestational diabetes need careful monitoring and screening for new chronic hypertension in the first 2 years postpartum., (Copyright © 2024 Elsevier Inc.
