Appropriate use criteria (AUC) aim to impact the provision of high-value care. This scoping review identified AUC regarding the procedural and operative treatment of cardiovascular disease and described the evolution of AUC in this space over time, including changes in the focus, strategy, and language of AUC. The summative presentation of these AUC identifies elements of AUC that may lead to successes in, and barriers to, implementation across disease processes, specialties, and societies. AUC topics include coronary artery disease, peripheral artery disease, valvular disease, venous disease, renal artery stenosis, and mesenteric ischemia, among others. [ABSTRACT FROM AUTHOR]

Percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) are the main interventional treatments for coronary artery disease (CAD) patients. Both procedures are constantly being perfected and developed. This study aims to analyze the evolution of intervention mortality rates of PCI and CABG in recent years in Spain. We use a database of all hospital discharges from CABG and PCI procedures in Spain during two periods, between the years 2010 to 2012 and 2016 to 2019. We elaborate two multivariate regression logistic models to test the differences in mortality between the two periods and the two procedures, adjusting the mortality rates by age, gender, and comorbidities. We find strong evidence that CABG significantly reduced mortality rates, especially in complex patients, while PCI remained almost constant. We also discuss how physicians incorporate the improvement in procedures’ performance into the decision-making for the recommendation of these two procedures in CAD patient management.

Background: Chronic diseases are associated with a high disease burden. Under- and overprovision of care as well as quality variation between health care providers persists, while current quality indicators rarely capture the patients' perspective. Capturing patient-reported outcome measures (PROMs) as well as patient-reported experience measures (PREMs) is becoming more and more important to identify gaps in care provision, prioritize services most valuable to patients, and aid patients' self-management. Objective: This study aims to measure the potential benefits and effectiveness of using electronic patient-reported outcome measures (ePROMs) and electronic patient-reported experience measures in a structured and population-based manner to enhance health care for chronic disease patients in Germany. Methods: This prospective cohort study aims to evaluate the potential benefits of PROM usage in patients with chronic diseases. We evaluate whether (1) digitally collected PROMs and PREMs can be used for health system performance assessment by generating a representative response of chronically diseased individuals with asthma, chronic obstructive pulmonary disease, diabetes, and coronary artery disease across Germany, and (2) based on the PROMs and PREMs, low-value care can be identified. As patient-reported outcomes (PROs) are rarely presented back to patients, (3) this study also examines patients' reactions to their PROM scores in the form of digital PRO feedback. For these purposes, randomly selected patients from a nationwide German insurer are digitally surveyed with generic and disease-specific PROMs and PREMs, as well as additional questions on their health-related behavior, 4 times over 1 year. Individual PRO feedback is presented back to patients longitudinally and compared to a peer group after each survey period. Patient-reported data is linked with health insurance data. Response rates, changes in health and experience outcomes over time, self-reported changes in health behavior, and health care system usage will be analyzed. Results: The PROMchronic study explores the usage of PROMs in patients with chronic diseases. Data collection began in October 2023, after the initial invitation letter. All the 200,000 potential patients have been invited to participate in the study. Data have not yet been analyzed. Publication of the interim results is planned for the autumn of 2024, and the results are planned to be published in 2025. Conclusions: We aim to fill the research gap on the population-based usage of PROMs and PREMs in patients with chronic diseases and add to the current understanding of PROM data-sharing with patients. The study's results can thereby inform whether a health care system-wide approach to collecting PROMs and PREMs can be used to identify low-value care, assess quality variation within and across chronic conditions, and determine whether PRO feedback is helpful and associated with any changes in patients' health behaviors.

• Carotid artery stenting (CAS) is common treatment for carotid artery stenosis. • Relationship between 30 day readmission and hospital volume for CAS not clarified. • Very high volume hospitals associated with decreased 30 day readmission for CAS. • Significant association for asymptomatic CAS patients, but not symptomatic patients. Endovascular carotid artery stenting (CAS) is a common treatment for carotid artery stenosis and stroke prevention. Previous studies have shown that high procedural volume centers are associated with improved patient outcomes. Unplanned 30-day readmissions, which are associated with significant expenses, are increasingly used as a metric of patient outcome. Despite prior studies evaluating associations between procedural volume and multiple outcomes, the association between very high CAS volume and short-term (30-day) readmission has not yet been evaluated in a large multicenter study. The National Readmissions Database (NRD) was analyzed retrospectively from 2010 to 2015 to evaluate the association between hospital procedural volume and patient outcomes in asymptomatic and symptomatic CAS patients. Very high volume centers (VHVC) were defined as the top 10% hospitals in terms of procedural volume, performing >= 79 procedures a year. Univariate and multivariate analyses of patient and hospital characteristics evaluated associations with short-term (30-day) readmissions (SR), long-term (90-day) readmissions (LR), index mortality, discharge disposition, major complications, and neurological complications. A total of 36,128 asymptomatic patients and 8,390 symptomatic patients who underwent CAS were identified. Asymptomatic CAS patients treated at VHVCs were associated with decreased likelihood of SR (OR 0.88, 95% CI 0.80–0.95, p = 0.003) and LR (OR 0.91, 95% CI 0.85–0.99, p = 0.037) compared to asymptomatic patients at non-VHVCs. There was no significant difference in SR or LR between symptomatic CAS patients treated at a VHVC vs. non-VHVC. Our findings provide additional evidence to support the role of experience in improved CAS treatment outcomes. [ABSTRACT FROM AUTHOR]

Background: Coronary artery diseases remain the leading cause of death in the world. The management of this condition has improved remarkably in the recent years owing to the development of new technical tools and multicentric registries. Objective: The aim of this study is to investigate the in-hospital and 1-year clinical outcomes of patients treated with percutaneous coronary intervention (PCI) in Tunisia. Methods: We will conduct a prospective multicentric observational study with patients older than 18 years who underwent PCI between January 31, 2020 and June 30, 2020. The primary end point is the occurrence of a major adverse cardiovascular event, defined as cardiovascular death, myocardial infarction, cerebrovascular accident, or target vessel revascularization with either repeat PCI or coronary artery bypass grafting (CABG). The secondary end points are procedural success rate, stent thrombosis, and the rate of redo PCI/CABG for in-stent restenosis. Results: In this study, the demographic profile and the general risk profile of Tunisian patients who underwent PCI and their end points will be analyzed. The complexity level of the procedures and the left main occlusion, bifurcation occlusion, and chronic total occlusion PCI will be analyzed, and immediate as well as long-term results will be determined. The National Tunisian Registry of PCI (NATURE-PCI) will be the first national multicentric registry of angioplasty in Africa. For this study, the institutional ethical committee approval was obtained (0223/2020). This trial consists of 97 cardiologists and 2498 patients who have undergone PCI with a 1-year follow-up period. Twenty-eight catheterization laboratories from both public (15 laboratories) and private (13 laboratories) sectors will enroll patients after receiving informed consent. Of the 2498 patients, 1897 (75.9%) are managed in the public sector and 601 (24.1%) are managed in the private sector. The COVID-19 pandemic started in Tunisia in March 2020; 719 patients (31.9%) were included before the COVID-19 pandemic and 1779 (60.1%) during the pandemic. The inclusion of patients has been finished, and we expect to publish the results by the end of 2022. Conclusions: This study would add data and provide a valuable opportunity for real-world clinical epidemiology and practice in the field of interventional cardiology in Tunisia with insights into the uptake of PCI in this limited-income region.

Introduction: Lower-extremity peripheral artery disease (PAD) can lead to a wide spectrum of symptoms that can progress from claudication to amputation. The prognostic nutritional index (PNI), which is calculated using the levels of albumin and lymphocyte, is an accepted indicator of immunological and nutritional status. In this study, the association between nutritional status determined using the PNI, and extremity amputation in patients with lower-extremity PAD was investigated. Methods: Lower-extremity PAD patients who had been admitted to the cardiology clinic of the Dışkapı Yıldırım Beyazıt Training & Research Hospital with stage 2b or higher claudication, and who were technically unsuitable for revascularization or underwent unsuccessful revascularization procedure were enrolled in this retrospective study. Patients were grouped according to whether or not limb amputation had been performed previously. Potential factors were tested to detect independent predictors for amputation with logistic regression analysis. Results: A study group was formed with 266 peripheral artery patients. The amputated group (39 patients) had a higher number of hypertensive (76.9% vs 57.7%; P = 0.032) and diabetic (92.3% vs 54.2%; P

Due to decreased blood supply and thereby oxygen and nutrient supply to the heart muscles, efficiency of the heart decreases. World has largest number of Coronary disease patients. Due to this reason, heart has to perform more work that leads to stress on it. This may be the major cause of heart attack. Proposed article gives an idea about tests of association which is used in situations where to evaluate whether there is any association between the variables under study like Heart Attack, which is segregated according to the age group by considering three major factors such as Coronary Artery Disease, Heart Failure and another disease affecting the heart, so that the number of persons from a particular population, age group get an attack due to a particular factor responsible, and the proportion of persons in the population prone to Heart attack.

Introduction: Ischaemic Heart Disease (IHD) or Coronary Artery Disease (CAD) is the most prevalent chronic disease and the main leading cause of death in the world, with more than half a million newly diagnosed IHD patients each year. Central to this are disorders of lipoprotein metabolism. Apolipoprotein B (Apo B) and Apolipoprotein A1 (Apo A1) are structural and functional components of lipoprotein particles that serve as transporters of cholesterol. Apo B and Apo A1 are among the emerging markers for Cardiovascular Diseases (CVD). Routine conventional lipid profile does not incorporate these markers. Aim: To determine the level of Apo A1 and Apo B in patients of IHD with or without Type II Diabetes Mellitus (T2DM) and analyse the significance of these parameters over the conventional lipid profile. Materials and Methods: The case-control study was conducted at Government Medical College, Bhavnagar, Gujarat, India from July 2013 to December 2013. The study consists of 100 participants including 50 having IHD only (Group I), 50 having IHD with T2DM (Group II) as study groups and 50 healthy individuals (Group III) as control. Various biochemical parameters including Apo B and Apo A1 were analysed and statistically evaluated to come to conclusion. Results: The demographic details of the participants which shows no significant different in age and gender among groups I, II and III. Apo B and A1 were elevated in group I and II and were found highly significant (p-value <0.0001) as compared to the group III. There was positive correlation of serum Apo B levels with total cholesterol (r=0.495, p-value <0.0001), Low-Density Lipoproteins (LDL-C) (r=0.526, p-value <0.0001) and Apo A1 (r=0.685, p-value <0.0001) in group I and LDL-C (r=0.468, p-value=0.001) and Apo A1 (r=0.754, p-value <0.0001) in group II. Similarly, Apo A1 levels were positively correlated with Apo B (r=0.685, p<0.0001) in group I and LDL-C (r=0.305, p-value=0.031) and Apo B (r=0.754, p-value <0.0001) in group II. Conclusion: As the Apo B and Apo A1 cover both atherogenic and antiatherogenic lipid parameters respectively, it can be used as a better predictor of development of IHD with and without T2DM in comparison to conventional parameters of lipid profile.

One of the diabetes mellitus (DM) complications is foot ulcers. Foot ulcers are influenced by many factors. DM puts patients at risk of injury because of visual impairment. Hyperglycemia can damage blood vessels, which results in peripheral artery disease (PAD). The purpose of this study was to find the relationship of visual impairment and PAD with diabetic foot ulcers.

Introduction: This study aims to compare the clinical outcomes of patients treated with Cre8TM versus Resolute Onyx™ stent. Material and Methods: In this retrospective study, all patients who underwent Stenting in the catheterization department of ShahidMadani Hospital between 2015 and 2018, were included. Angiographic and angioplasty findings were recorded. The primary end point, which includes total mortality, myocardial infarction, revascularization (adverse events) were recorded. Results: The mortality rates were similar in both groups. Moreover the myocardial infarction and repeated revascularization did not differ in both groups (p>0.05).The rates of adverse events wasn't significantly different between the two groups. Conclusion: Our study showed that efficacy and safety of Cre8™ stents is non-inferior to the Resolute Onyx™ stent. [ABSTRACT FROM AUTHOR]

Background: The application of machine learning in health care often necessitates the use of hierarchical codes such as the International Classification of Diseases (ICD) and Anatomical Therapeutic Chemical (ATC) systems. These codes classify diseases and medications, respectively, thereby forming extensive data dimensions. Unsupervised feature selection tackles the "curse of dimensionality" and helps to improve the accuracy and performance of supervised learning models by reducing the number of irrelevant or redundant features and avoiding overfitting. Techniques for unsupervised feature selection, such as filter, wrapper, and embedded methods, are implemented to select the most important features with the most intrinsic information. However, they face challenges due to the sheer volume of ICD and ATC codes and the hierarchical structures of these systems., Objective: The objective of this study was to compare several unsupervised feature selection methods for ICD and ATC code databases of patients with coronary artery disease in different aspects of performance and complexity and select the best set of features representing these patients., Methods: We compared several unsupervised feature selection methods for 2 ICD and 1 ATC code databases of 51,506 patients with coronary artery disease in Alberta, Canada. Specifically, we used the Laplacian score, unsupervised feature selection for multicluster data, autoencoder-inspired unsupervised feature selection, principal feature analysis, and concrete autoencoders with and without ICD or ATC tree weight adjustment to select the 100 best features from over 9000 ICD and 2000 ATC codes. We assessed the selected features based on their ability to reconstruct the initial feature space and predict 90-day mortality following discharge. We also compared the complexity of the selected features by mean code level in the ICD or ATC tree and the interpretability of the features in the mortality prediction task using Shapley analysis., Results: In feature space reconstruction and mortality prediction, the concrete autoencoder-based methods outperformed other techniques. Particularly, a weight-adjusted concrete autoencoder variant demonstrated improved reconstruction accuracy and significant predictive performance enhancement, confirmed by DeLong and McNemar tests (P<.05). Concrete autoencoders preferred more general codes, and they consistently reconstructed all features accurately. Additionally, features selected by weight-adjusted concrete autoencoders yielded higher Shapley values in mortality prediction than most alternatives., Conclusions: This study scrutinized 5 feature selection methods in ICD and ATC code data sets in an unsupervised context. Our findings underscore the superiority of the concrete autoencoder method in selecting salient features that represent the entire data set, offering a potential asset for subsequent machine learning research. We also present a novel weight adjustment approach for the concrete autoencoders specifically tailored for ICD and ATC code data sets to enhance the generalizability and interpretability of the selected features., (©Peyman Ghasemi, Joon Lee.

The double-kiss mini-crush (DKMC) technique has been successfully deployed in the past for the treatment of complex coronary lesions even for left main lesions. Our case report consists of a proof-of-principle that the DKMC technique can be successfully translated as well to the field of complex renal artery lesions. Insightful thinking out-of-the "coronary" box in concert with skillful off-label application of coronary stenting procedures may open the gate for unprecedented opportunities for the treatment of difficult-to-tackle in-stent restenosis in the renal circulation., (© 2024 Wiley Periodicals LLC.)

The prognostic nutritional index (PNI), which is calculated using the levels of albumin and lymphocyte, is an accepted indicator of immunological and nutritional status. In this study, the association between nutritional status determined using the PNI, and extremity amputation in patients with lower-extremity PAD was investigated.

Patients were grouped according to whether or not limb amputation had been performed previously. Potential factors were tested to detect independent predictors for amputation with logistic regression analysis. Results: A study group was formed with 266 peripheral artery patients. The amputated group (39 patients) had a higher number of hypertensive (76.9% vs 57.7%; P = 0.032) and diabetic (92.3% vs 54.2%; P <0.001) patients than those in the non-amputated group (227 patients). The median PNI value of the amputated group was lower than that of the non-amputated group (31.8 vs 39.4; P <0.001). Multivariate logistic regression showed that the PNI (OR: 0.905, 95% CI: 0.859 – 0.954; P <0.001) was independently related with amputation. Conclusion: Immune-nutritional status based on PNI was independently associated with limb amputation in patients with lower-extremity PAD. [ABSTRACT FROM AUTHOR]

Aims  To investigate the impact of applying coronary computed tomography angiography (CCTA), as the recommended first-line diagnostic test in patients with suspected chronic coronary syndrome (CCS) on the use of invasive coronary angiography (ICA) and revascularization practice. Methods and results  We included all patients undergoing a first-time CCTA (n  = 53555) and first-time ICA (n  = 41451) from 2008 to 2017 due to suspected CCS in Western Denmark (3.3 million inhabitants). The number of CCTA procedures increased from 352 (2008) to 7739 (2017) (2098%), ICA examinations declined from 4538 to 3766 (17%). The average proportion of no- or non-obstructive coronary artery disease by CCTA was 77.5%. Referral to ICA after CCTA occurred in 16.9% of patients in 2008–10 vs. 13.9% in 2014–17 (P  < 0.0001). Revascularization in patients referred to ICA after CCTA increased from 33.8% in 2008–10 vs. 44.4% in 2014–17 (P  < 0.0001). The revascularization proportion in patients undergoing ICA with no preceding CCTA was 32.3% in 2008–10 vs. 33.3% in (2014–17) (P  = 0.1063). Stratified by age, the overall revascularization proportion increased in the younger age groups and was unchanged or decreased in older age groups: <50 years: 60% increase, 50–59 years: 33% increase, 60–69 years: 0%, and >70 years: 9.5% decrease. Conclusion  The introduction of CCTA as a first-line diagnostic test in patients with suspected CCS does not associate with increased use of invasive angiography and seems to have facilitated a more appropriate revascularization practice.

We report the case of a 77-year-old woman affected by coronavirus disease-19 (COVID-19) who developed an occlusive arterial disease of the lower limb requiring a left leg amputation. We studied the mechanisms of vascular damage by SARS-CoV-2 by means of a comprehensive multi-technique in situ analysis on the diseased popliteal arterial district, including immunohistochemistry (IHC), transmission electron microscopy (TEM) and miRNA analysis. At histological analyses, we observed a lymphocytic inflammatory infiltrate, oedema and endothelialitis of adventitial vasa vasorum while the media was normal and the intima had only minor changes. The vasa vasorum expressed the ACE2 receptor and factor VIII; compared with the controls, VEGFR2 staining was reduced. TEM analyses showed endothelial injury and numerous Weibel–Palade bodies in the cytoplasm. No coronavirus particle was seen. IL-6 protein and mRNA, together with miR-155-5p and miRs-27a-5p, which can target IL-6, were significantly increased compared with that in the controls. Our case report suggests an involvement of adventitial artery microcirculation by inflammation in the course of COVID-19. Without evident signs of current infection by SARS-CoV-2, endothelial cells show a spectrum of structural and functional alterations that can fuel the cardiovascular complications observed in people infected with SARS-CoV-2.

Lumen vessel sizing is important for optimization of interventional outcomes for treatment of vascular disease. The objective of this study is to develop an injection-less method to determine the lumen diameter, using multiple frequencies that eliminates the need for saline injections. We utilize the same electrical conductance devices developed for the two-injection method. A mathematical electrical model was devised to estimate the lumen area and diameter of the arteries. In vitro experiments were used to validate the method for various lumen diameters with both 5-5-5 (peripheral) and 2-2-2 (coronary) spacing conductance guidewires. The majority of 11 vessel data fall within one standard deviation and all the data fall within two standard deviations. The results indicate that the two-frequency model can reasonably predict the lumen diameter in an in-vitro test set-up. Our findings show that this approach can potentially translate to in vivo which would enable pull-back to reconstruct the lumen area profile of the vessel.

Coronary microvascular dysfunction has recently emerged as a major independent prognostic factor and can be invasively assessed by coronary flow reserve (CFR) and the index of microvascular resistance (IMR). The incremental prognostic value of myocardial ischemia from SPECT myocardial perfusion imaging (MPI) over clinical characteristics, cardiac risk factors, and stress test data for the prediction of hard cardiac events (myocardial infarction and cardiac death) has been well demonstrated over the last two decades regardless of the absence or presence of epicardial CAD. Recently developed semi-conductor, cardiac-dedicated cameras allow for decreased acquisition times and systematic procubitus and decubitus acquisitions thereby limiting the occurrence of false positives historically attributable to artefactual motion, attenuation, and digestive artifacts. It is therefore likely that pathophysiological causes rather than acquisition artifacts might underlie SPECT perfusion abnormalities. Here, we report four representative examples of patients presenting with ischemia in the setting of no obstructive CAD and normal fractional flow reserve together with elevated IMR and low CFR. The results indicate that ischemia from SPECT MPI could result from microvascular dysfunction in patients without obstructive CAD and should be considered as a prognostic factor for hard cardiac events.

Background: In observational studies, patients with HIV have higher levels of soluble ST2 (sST2), galectin-3, and growth differentiation factor-15 (GDF-15) than non-HIV controls. As statins exert pleiotropic immunomodulatory effects that may affect markers of myocardial fibrosis, the objective of the current study is to determine whether biomarkers of myocardial fibrosis reflecting subclinical pathology may be modified by statin therapy in patients with HIV. Setting and Methods: Forty HIV+ men and women participated in a single center 12-month randomized, double-blind placebo-controlled trial of atorvastatin 40 mg every day vs. placebo. At baseline and 12-months, sST2, GDF-15, galectin-3 were measured. Results: The changes in sST2 were -0.310 (-4.195, 2.075) vs. 1.163 (0.624, 4.715) ng/mL, median (interquartile range) atorvastatin vs. placebo (P = 0.04). The change in sST2 was significantly related to changes in monocyte activation marker sCD14 (r = 0.63, P < 0.0001) and MCP (r = 0.52, P = 0.0009), markers of generalized inflammation hs-IL-6 (r = 0.58, P = 0.0002), oxLDL (r = 0.49, P = 0.002), and GDF-15 (r = 0.54, P = 0.0008). Conclusions: sST2, a member of the IL-1 receptor family and a marker of fibrosis and inflammation increases over time among patients with HIV and this increase is attenuated by statin therapy in HIV. This effect may relate to immunomodulatory mechanisms of statins. [ABSTRACT FROM AUTHOR]

Retroperitoneal neoplasias may be a diagnostic and therapeutic challenge for the clinician. Case report: A 56 year old male with prior history of type 2 diabetes consults with right inferior limb edema and paresthesias. He was diagnosed of deep vein thrombosis and lymph node conglomerate by ultrasound. A CT scan was performed, observing great retro peritoneal mass enclosing vascular and nervous structures. An initial histological diagnosis of hamartoma was made. Surgery was scheduled to remove the tumour, ligation of thrombosed external iliac vein and the external iliac artery was preserved. Intraoperative histological findings suggested sarcoma, definite studies showed presence of high grade liposarcoma. Two weeks after the intervention, the patient presents in hypovolemic shock due to rupture of the right external iliac artery. Emergent ligation of the artery and femorofemoral bypass was performed, with adequate postoperatory recovery. The patient was discharged and continued adjuvant oncology treatment and was exitus six months later. Discussion: Sarcomas are the most frequent primary retroperitoneal tumours. They are difficult to diagnose and often have untimely treatment. Sarcomas tend to be asymptomatic, or present with local compression symptoms, affecting vascular and nervous structures. CT scan is the gold standard for diagnostic imaging. Treatment requires a multidisciplinary approach, surgical resection as the main therapy; radio and chemotherapy represents a solution for irresectable or high grade malignancies.

Objective: The clinical outcome and quality of life of CHD patients are greatly influenced by medication adherence. Non-adherence of CHD patients to treatment results in sub-optimal clinical outcomes and increasing costs. This study aims to describe effectiveness of the intervention to improve the medication adherence in CHD patients., Methods: Systematic review methodology was used in this study. Scopus and PubMed were used to search the relevant article systematically. The outcome measured was medication adherence in coronary heart disease patients., Results: Final screening was 31 articles that met the inclusion criteria in this study of 788 articles. Selection processes the article used the PRISMA guideline. Most of the articles (15 articles) use interventions that utilize information technology (IT) as known with m-health in the form of text messages, website, and smartphone-based applications in increasing medication adherence in CHD patients. The non m-health interventions developed are in the form of self-efficacy programs, monitoring and education by health workers or care workers, pharmacy care by clinical pharmacists, and the use of drugs in the form of multi-capsules. The results of most intervention with m-health can improve the medication adherence in CHD patient effectively. Education and motivation program by professional health care and multi-capsules also increasing the medication adherence in the intervention control. There was a decrease of medication adherence in some articles with long time follow-up that can be attention for the professional health care to manage the patient adherent., Conclusion: The medication adherence in CHD patient can be improve by various program. Modification of m-health and non m-health intervention can be resolved to increase the communication, motivation, and knowledge about medication adherence in CHD patients., Competing Interests: Conflict of interest: There is no conflict of interest in this study., (© 2023 Saudi Heart Association.)

Cardiovascular disease has remained one of the leading causes of mortality in the world. The basic pathophysiology of coronary artery disease (CAD) is a reduction of the blood flow in coronary vessels, leading to restricted blood flow to the heart muscle. Both modifiable and non-modifiable risk factors contribute to its multifactorial etiology. The clinical presentation ranges from asymptomatic to typical symptoms like chest pain, shortness of breath, and left arm or jaw pain. The purpose of this review is to investigate and analyze the variation of CAD depending on the biological sex, age, race, or ethnicity and how it might differ in the studied population while comparing the symptoms and prognosis of CAD. For this research, PubMed's database was used. A total of 926 articles were selected using pre-determined inclusion and exclusion criteria, with 74 articles eligible to be included in the narrative review. Studies were selected from the general population of patients with CAD, regardless of their severity, stage of diagnosis, and treatment plan. The scale for the assessment of non-systematic review articles (SANRA) was used to assess the quality of the study. As humans age, the incidence of CAD increases, and people over 75 are more likely to have multiple-vessel CAD. It has been observed that South Asians have the highest rate of CAD at 24%, while the White population has the lowest at 8%. The prevalence of CAD also depends on race, with the White population having the lowest rate at 3.2%, followed by Hispanics at 5%, Black women at 5.2%, and Black men at 5.7%. Younger Black women tend to have more chest pain. Men with CAD commonly experience chest pain, and women are more likely to present with atypical symptoms. Modifiable risk factors such as smoking and alcoholism are more commonly observed in young men than in young women. Coronary artery disease in the elderly, female, minority, and Black patients is associated with a higher mortality rate. Acknowledging the prevalence of certain risk factors, signs, results, and responses to treatment in certain socio-demographic groups, as well as the provision and accessibility of diagnosis and treatment, would lead to a better outcome for all individuals. The impact of this shift can range from an earlier diagnosis of CAD to a faster and more customized treatment plan tailored to each patient's individual requirements., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Lima Dos Santos et al.)

Background: Fibrinogen has been identified as an independent risk factor for cardiovascular disease and associated with traditional cardiovascular risk factors. Few reports have so far investigated the relationship between fibrinogen levels and the extent of coronary artery disease (CAD) as evaluated by coronary angiography. Therefore the current study was carried out to evaluate the relationship between fibrinogen levels and the extent of CAD as evidenced by coronary angiography. Method: A total of 210 patients having ischemic heart disease including chronic stable angina, unstable angina, non-ST elevated myocardial infarction & ST elevated myocardial infarction were evaluated in National Institute of Cardiovascular Disease (NICVD), Dhaka with a view to find out the relationship between fibrinogen levels and the extent of CAD undergoing coronary angiography. Patients were divided in 3 groups according to fibrinogen levels: Group I = fibrinogen levels <400 mg/dl, Group II = fibrinogen levels (400-600) mg/dl, Group III = fibrinogen levels > 600 mg/dl. In this study, angiographic severity was assessed by vessel score, stenosis score and lesion morphology and tries to find out their relationship with angiographic severity and fibrinogen level. Result: Using a prospective analytic design we studied 210 patients who were divided into 3 groups : Vessel score in Group I, Group II & Group III were 1.14 ± 0.56, 2.24 ± 0.58, & 3.00 ± 0.65 respectively which was statistically significant (p < 0.01) and Stenosis score in group-I, group-II & group-III were 6.00 ± 4.19, 18.72 ± 4.94, & 32.41 ± 15.75 respectively which was statistically significant (p < 0.01). Regarding morphology of the lesions, complex lesions in group I, group II & group III were 21%, 32% & 39% respectively (statistically significant; p < 0.01). Conclusion: High fibrinogen level is independently and significantly associated with more severe coronary artery disease. Serum fibrinogen can be used as a new and even simpler tool for risk stratification in acute coronary syndrome. [ABSTRACT FROM AUTHOR]

Aims To examine the diagnostic accuracy of sensitive cardiac troponin (cTn) assays in elderly patients, since elevated levels with sensitive cTn assays were reported in 20% of elderly patients without acute myocardial infarction (AMI). Methods and results In this multi-centre study, we included 1098 consecutive patients presenting with symptoms suggestive of AMI, 406 (37%) were >70 years old. Measurement of three investigational sensitive cTn assays [Roche high-sensitive cTnT (hs-cTnT), Siemens cTnI-Ultra, and Abbott-Architect cTnI) and the standard assay (Roche cTnT) was performed in a blinded fashion. The final diagnosis was adjudicated by two independent cardiologists. Acute myocardial infarction was the adjudicated final diagnosis in 24% of elderly patients. Among elderly patients without AMI, baseline cTn levels were elevated above the 99th percentile in 51% with Roche hs-cTnT, in 17% with Siemens TnI-Ultra, and 13% with Abbott-Architect cTnI. The diagnostic accuracy as quantified by the area under the receiver operating characteristic (ROC) curve (AUC) was significantly greater for the sensitive cTn assays compared with the standard assay (AUC for Roche hs-cTnT, 0.94; Siemens cTnI-Ultra, 0.95; and Abbott-Architect cTnI, 0.95 vs. AUC for the standard assay, 0.90; P < 0.05 for comparisons). The best cut-offs for the sensitive cTn-assays determined by the ROC-curve in elderly patients differed clearly from those in younger patients. Furthermore, the prognostic value regarding 90-day mortality varied among the sensitive cTn assays. Conclusion Sensitive cTn assays have high diagnostic accuracy also in the elderly. Mild elevations are common in elderly non-AMI patients, therefore the optimal cut-off levels are substantially higher in elderly as compared with younger patients. Furthermore, sensitive cTn assays yielded different prognostic value (ClinicalTrials.gov number, NCT00470587). [ABSTRACT FROM PUBLISHER]

The article presents a study which examined the role of growth-differentiation factor-15 (GDF-15) for long-term risk prediction in patients stabilized after an episode of non-ST-segment-elevation acute coronary syndrome. Results show that GDF-15 levels slightly decreased at randomization. GDF-15 was also related to cardiovascular risk factors and biochemical markers such as renal dysfunction and inflammation.

Four patients with chronically well-compensated, non-ischemic dilated cardiomyopathy (NIDC) presented with occlusive atherosclerotic coronary artery disease as the cause of subacute decompensation (FC III–IV heart failure) 8–13 years following the diagnosis of NIDC. In addition to the atherogenic condition of heart failure, 3 of the patients acquired major atherosclerotic risk factors (dyslipidemia, diabetes mellitus) during the interval between the diagnoses of NIDC and problematic atherosclerotic coronary disease. For each patient, dyspnea on exertion was the primary symptom during the subacute decompensation. Only 1 patient noted precordial chest pain in the form of atypical angina during some of the dyspneic events. The diagnosis of occlusive coronary artery disease was made by coronary angiography, followed by angioplasty-stent deployment in 3 patients and coronary artery bypass surgery in 1; all improved to their baseline FC I–II status following these coronary interventions. As survival of patients with NIDC increases, occlusive coronary artery disease may enter an otherwise stable clinical course to provoke unanticipated decompensation (principally dyspnea), and can do so without causing angina pectoris as a heralding symptom.

This article focuses on a study related to evaluation of the mortality rate in survivors of myocardial infarction (MI) with impaired left ventricular function and its relation to pre-hospital discharge baseline characteristics. The study shows that the 1-year and 2-year mortality rates among patients discharged from the hospital after experiencing an acute MI with an ejection fraction of more than 40% have decreased markedly compared to the rates cited in more recent studies evaluating post-hospital discharge mortality among patients with cardiac dysfunction, with reported rates of 10 to more than 20% at 1 year.

We report the case of a 77-year-old woman affected by coronavirus disease-19 (COVID-19) who developed an occlusive arterial disease of the lower limb requiring a left leg amputation. We studied the mechanisms of vascular damage by SARS-CoV-2 by means of a comprehensive multi-technique in situ analysis on the diseased popliteal arterial district, including immunohistochemistry (IHC), transmission electron microscopy (TEM) and miRNA analysis. At histological analyses, we observed a lymphocytic inflammatory infiltrate, oedema and endothelialitis of adventitial vasa vasorum while the media was normal and the intima had only minor changes. The vasa vasorum expressed the ACE2 receptor and factor VIII; compared with the controls, VEGFR2 staining was reduced. TEM analyses showed endothelial injury and numerous Weibel–Palade bodies in the cytoplasm. No coronavirus particle was seen. IL-6 protein and mRNA, together with miR-155-5p and miRs-27a-5p, which can target IL-6, were significantly increased compared with that in the controls. Our case report suggests an involvement of adventitial artery microcirculation by inflammation in the course of COVID-19. Without evident signs of current infection by SARS-CoV-2, endothelial cells show a spectrum of structural and functional alterations that can fuel the cardiovascular complications observed in people infected with SARS-CoV-2.
