Introduction: Patients with acute coronary syndrome (ACS) often experience high levels of anxiety, which can significantly impact their prognosis. However, evidence regarding anxiety reduction by aromatherapy in patients with ACS is lacking. This study aimed to investigate the effects of aromatherapy on anxiety in patients with ACS. Methods: The literature search was conducted using PubMed, CINAHL, Embase, Web of Science, Cochrane Library, and PsycINFO from their inception until February 21, 2024. Based on inclusion criteria, randomized controlled trials (RCTs) on aromatherapy in patients with ACS aged ≥ 18 years were included. The risk of bias in the included studies was assessed using the revised Cochrane risk-of-bias tool for RCTs. Results: A total of 14 studies were included in the final analysis. Aromatherapy significantly reduced anxiety among patients with ACS, with a large effect size (standardized mean difference [SMD] = -1.66, 95% confidence interval [CI]: -2.47 to -0.85). The effect on systolic blood pressure (SBP) was -0.65 (95% CI: -1.15 to -0.15), indicating a moderate effect size, whereas there was no significant effect on diastolic blood pressure. Inhalation therapy demonstrated a large effect size (SMD = -1.70, 95% CI: -2.33 to -1.08), whereas massage therapy did not show a significant effect on reducing anxiety. Discussion/Conclusions: The findings show that aromatherapy can effectively reduce anxiety and SBP in patients with ACS. In particular, inhalation therapy showed a significant effect on reducing anxiety levels. Applying aromatherapy in clinical settings to reduce anxiety among patients with ACS should be considered. However, the limited number of studies analyzed hinders a comprehensive evaluation of the effectiveness of massage therapy. Hence, further research is necessary to elucidate its potential role in reducing anxiety among patients with ACS. [ABSTRACT FROM AUTHOR]

Individuals have different rumination patterns after experiencing traumatic events in different cultural backgrounds and situations. This study aimed to explore the experience of Chinese young and middle-aged patients with acute coronary syndrome (ACS) to understand the content and nature of their rumination. Sixteen participants were selected using the purposive sampling method in the First Affiliated Hospital of Soochow University from May 2023 to December 2023. Data were collected using semi-structured interviews and analyzed using Colaizzi's seven-step phenomenological method. The participants went through two successive stages: non-adaptive rumination and adaptive rumination. During the initial admission phase, all the participants experienced varying degrees of non-adaptive rumination. Non-adaptive rumination included four sub-themes: worry or anxiety of daily activities and medical therapy (37.50%), fear of unpredictable outcomes and death (37.50%), sadness of maladjustment (25.00%), and remorse of carelessness (12.50%). During the period of stable condition and pre-discharge, the participants received health education and gradually all transitioned to adaptive rumination. Adaptive rumination included four sub-themes: tracing of disease processes (100%), enhancement of disease cognition (81.25%), improvement of health awareness (62.50%), and adjustment of lifestyle cognition (100%). In conclusion, although the Chinese young and middle-aged patients with ACS experienced negative emotions after a traumatic cardiac event, they gradually made positive changes, and optimism and information support played important roles in this transition. The results of this study provide a fundamental understanding of rumination experiences in Chinese young and middle-aged patients with ACS and provide new data for healthcare providers when designing intervention programs to enhance post-traumatic growth in these patients.

Background: Although guidelines recommend guideline‐directed medical therapy (GDMT) for patients with acute coronary syndrome (ACS), implementation is limited in clinical practice. Aim: To assess the level of GDMT in ACS patients after discharge who attended cardiac rehabilitation (CR) programs and association with clinical outcomes. Method: A cross‐sectional study was conducted in 13 rural and 10 metropolitan CR programs via all modes of delivery (face‐to‐face, telephone, or general practice‐hybrid) operating in South Australia, Australia. ACS patients were included if they were ≥18 years of age and were referred and attended CR programs with medication details recorded in their hospital discharge summary. GDMT was assessed according to the Australian clinical guidelines for the management of acute coronary syndromes 2016. Prescription of all the four recommended medication classes was considered optimal. Logistic regression and χ2 test were used for association. Ethical approval was granted by the South Australian Department for Health and Wellbeing Human Research Ethics Committee (Reference No. HREC/15/SAH/63) and the Northern Territory Department of Health Human Research Ethics Committee (Reference No. HREC 2015‐2484) which included a waiver of consent per the National Statement on Ethical Conduct in Human Research and the study conforms with the Good Clinical Practice Guidelines. Results: Of the 1229 patients included, 74.6% were male and 41.1% had acute myocardial infarction. Only 39.7% of patients received optimal prescription. Prescription of any three or two medication class combinations occurred for 78.3% and 94.1% of patients, respectively. Optimal GDMT was associated with fewer hospital admissions (odds ratio = 0.647, 95% confidence interval 0.424–0.987, p = 0.043) with no significant gender association. Women were less likely to be prescribed angiotensin converting enzyme inhibitors (p = 0.003), angiotensin receptor blockers (p = 0.007), statins (p = 0.005), and any two (p < 0.001) and three combinations (p = 0.023) of medication classes. Conclusion: GDMT prescription was suboptimal in patients with ACS before attendance at CR. Primary care and CR clinicians have missed an opportunity to implement best practice guideline recommendations, particularly for women. [ABSTRACT FROM AUTHOR]

Background: The comorbidity of acute coronary syndrome and diabetes affects patient prognoses. Therefore, it is important to manage these diseases simultaneously. Purpose: In this study, the effect of nursing counseling on treatment compliance was investigated in patients who had received surgical treatment for acute coronary syndrome and had been recently diagnosed with diabetes. Methods: A quasi-experimental design with pretest–posttest control group was used. The study sample consisted of 60 patients (intervention group = 30, control group = 30). The data were collected using a patient information form, the Patient Learning Needs Scale, and the Scale for Patient Compliance with Type 2 Diabetes Mellitus Treatment. This study was conducted in compliance with the Transparent Reporting of Evaluations with Nonrandomized Designs checklist. Results: The intervention group earned significantly higher posttest scores on the Patient Learning Needs total scale and subscales than the control group. Moreover, intervention group compliance with treatment was higher than that of the control group. Furthermore, although significant improvements were found in the average posttest body mass index, fasting blood glucose, HbA1c, total cholesterol, triglyceride, and low-density lipoprotein cholesterol values of the control group, the between-group differences in these values were not significant. Conclusions/Implications for Practice: It is important for nurses to provide counseling services that align with the learning needs of their patients. Also, nursing counseling units should be created and staffed by both specialist nurses and nurse trainers working in healthcare institutions. [ABSTRACT FROM AUTHOR]

Purpose: The aim of the study was to assess influence of clinician-related factors on adherence to the American heart association guidelines for acute coronary syndrome among clinicians at Kenya Ports Authority clinics in Mombasa, Kenya. Methodology: A descriptive cross-sectional study involving quantitative methods of data collection was adopted. An interviewer administered questionnaire was used for data collection. The study was carried out in Kenya Ports Authority clinics in Mombasa, Kenya. The target population was 106 clinicians attending to patients who present with Acute Coronary Syndrome at the KPA clinics in Mombasa. A census method was used to determine the study participants. The sample size was made up of a hundred and six participants. The clinicians who consented to participate in the study were included while those who were on sick off, leave or who recently joined the clinic were excluded. Pretesting of the study tool was done at the Kenya Pipeline Clinic Mombasa. Data analysis was done using Statistical Package for Social Sciences version 25 and presented via tables. Findings: The study results showed that at 95% level of confidence (ρ-value = 0.05%), there was a significant association between gender (α=0.025), work experience (α=0.016), job cadre (α=0.014) and training received (α=0.022) on adherence to the American Heart Association Guidelines for Acute Coronary Syndrome among clinicians at Kenya Ports Authority clinics in Mombasa, Kenya. The association was insignificant between age (α=0.178), education level (α=0.439) and specialization (α=0.489) on adherence to the AHA guidelines. Unique Contribution to Theory, Practice and Policy: The study recommends that the KPA management should increase the medical budget to ensure availability of adequate resources for ACS patient management. These resources include adequate staffing, medication, equipment, and staff training costs. The clinic management should ensure that medications such as aspirin, morphine and nitroglycerine are readily available and accessible at patients care points. The KPA clinic management to formulate a simple algorithm that outlines the steps to be taken when managing ACS patients. The study recommends that the clinics should assess their equipment reqularly for maintenance controls to ensure efficiency. The study further recommends random assessments and post care audits to assess the adherence to ACS guidelines among clinicians. Training associated with adherence to the AHA guidelines and as such, KPA should continue offering training and education on the latest AHA guidelines for ACS to ensure updated guidelines for practice.

Background: Chest pain is a frequent symptom suffered by adult patients attended by ambulance. Evidence suggests female patients may suffer different symptoms to their male counterparts, potentiating differences in pre-hospital time delays, assessment and treatment. Objective: To explore the sex differences in the pre-hospital ambulance delay, assessment and treatment of patients with acute coronary syndrome (ACS). Methods: A rapid evidence review was conducted following the Cochrane rapid review guidelines. MEDLINE and CINAHL Complete were searched via EBSCOhost on 2 February 2023, and reference lists of included studies and reviews were screened. The Joanna Briggs Institute checklist for analytical cross-sectional studies was used to perform critical appraisal, and a narrative synthesis was conducted. Results: From 216 articles screened, nine were included, representing over 3.1 million patients from five different countries. Female patients were more likely to suffer delays in time to first electrocardiogram (ECG) and delays in transport time to the emergency department by ambulance. Female patients were also less likely to receive an ECG, aspirin, glyceryl trinitrate and other analgesics. Conclusion: There are sex disparities in the pre-hospital ambulance delay, assessment and treatment of patients with ACS. Future research is urgently needed to fully understand the reasons for these observations. [ABSTRACT FROM AUTHOR]

Background Data about the clinical benefit from initial low-density lipoprotein cholesterol (LDL-C) reduction with lipid lowering treatment for secondary prevention and risk of major vascular events amongst older as compared with younger individuals treated during routine clinical care are limited. We investigated this in a nationwide cohort. Methods Individuals aged ≥ 50 years with a first-time hospitalisation for a cardiovascular event (index event, including acute coronary syndrome, non-haemorrhagic stroke, transient ischaemic attack and coronary revascularisation), 1 January 2008 to 31 October 2018, who subsequently used lipid lowering treatment, and had an LDL-C measurement before and after the event were included. Hazard ratios (HRs) for major vascular events per 1 mmol/L reduction in LDL-C were estimated for the included 21,751 older and 22,681 younger individuals (≥/<70 years old) using Cox regression. Results LDL-C lowering was associated with a 12% lower risk of major vascular events in older individuals per 1 mmol/L reduction in LDL-C (HR 0.88, 95% confidence interval [CI] 0.84–0.93), with no significant difference compared with the risk reduction amongst younger individuals (HR 0.88, 95% CI 0.83–0.93; P -value for difference between age groups: 0.86). The risk reduction was more pronounced when post hoc restricting, as a proxy for compliance, to new users with an LDL-C reduction above the lowest decile for both older (0.81, 95% CI 0.73–0.90) and younger (0.81, 95% CI 0.72–0.91) individuals. Conclusions This study strongly supports a similar relative clinical benefit of LDL-C reduction with lipid lowering treatment for secondary prevention of major vascular events amongst individuals aged ≥70 and <70 years.

Objective The aim of this study was to investigate fatty acids, lipid mediator levels, and the desaturase index rates on different acute coronary syndrome types and their possible relationship with routine lipid parameters. Methods The study included 81 patients with myocardial infarction (MI), 20 patients with unstable angina pectoris, and 31 healthy people. Fatty acids, CD59, lipoxin A4, 8-isoprostane, serum lipids, albumin, C-reactive protein (CRP), and high sensitive troponin levels were measured in all participants. Results When the fatty acid groups were evaluated as a ratio of albumin, MUFA/albumin and SFA/albumin ratios were significantly higher in the MI group compared to the control group. Although CD59 and lipoxin A4 levels were higher in the control group, there was no significant differences between the groups. When lipoxin A4/CRP and CD59/CRP ratios were evaluated, the results were significantly lower than those in the control group.  Conclusion Lipid mediators may be useful in treating atherosclerosis by contributing to the resolution of inflammation.

This article presents a study on gender differences in individuals with acute coronary syndrome (ACS). The study found that women often experienced asymptomatic symptoms of ACS, while men were more likely to receive certain treatments. The study suggests that healthcare professionals should be aware of these gender differences and provide appropriate care. Further research is needed to fully understand these differences.

The article presents the discussion on management of non-ST-elevation acute coronary syndromes failed to demonstrate more use of guideline-recommended care or better outcomes. Topics include group of hospitals participating in other registry studies for preventing contamination among patients at the same hospital undergoing different care; and composite of CV death, myocardial infarction, new heart failure hospital admissions, or readmissions for a CV event within 12 months.

Background. Percutaneous coronary intervention using a drug-eluting stent (DES) is a common therapeutic option for acute coronary syndrome (ACS). However, stent-associated complications, such as bleeding associated with dual antiplatelet therapy, in-stent restenosis, stent thrombosis, and neoatherosclerosis, remain. Drug-coated balloons (DCBs) are expected to reduce stent-associated complications. This study aimed to assess the efficacy of DCB therapy and compare it with that of DES therapy in patients with ACS. Materials and Methods. In this single-center, retrospective, observational study, we examined all patients with ACS treated with DCB or DES between July 2014 and November 2020. Patients with left main trunk lesions were excluded. The primary outcome was a composite of major adverse cardiovascular events (MACE: cardiac death, myocardial infarction, and target lesion revascularization) at one year. Results. Three hundred and seventy-two patients were treated with DES, and 83 patients were treated with DCB. MACE occurred in 10 (12.0%) patients in the DCB group and in 50 (13.4%) patients in the DES group (P = 0.73). Conclusions. DCB is a valuable and effective therapy for patients with ACS. Moreover, DCB may become an alternative therapy for DES in patients with ACS. [ABSTRACT FROM AUTHOR]

Key content: Maternal mortality from cardiovascular disease has not improved in almost 20 years; this contrasts to significant sustained improvement in cardiovascular outcomes in the nonpregnant population, particularly regarding acute coronary syndrome (ACS).Many of the women who died in recent MBRRACE‐UK reports presented with cardiac symptoms and signs, but this was not always recognised upon clinical review.The incidence of ACS is increasing alongside advancing maternal age, with an accompanying increased prevalence of typical and pregnancy‐specific cardiac risk factors.Early involvement of senior clinicians and a multidisciplinary approach is crucial for improving maternal outcomes.Counselling women on long term prognosis and implications for future pregnancy is vital. Learning objectives: To be aware of the latest data for ACS in pregnancy, including the changing trends in prevalence of this condition and the suggested reasoning behind this.To understand the various presentations of ACS in pregnancy and its differential diagnosis.To understand the possible investigation and management of ACS in pregnancy in a multidisciplinary setting.

Background: Disparities in cardiovascular outcomes between Aboriginal and Torres Strait Islander Australians and non‐Indigenous Australians persist. This has previously been attributed to a combination of differences in burden of cardiovascular disease risk factors, and inpatient access to guideline‐recommended care. Aims: To assess differences in inpatient access to guideline‐recommended acute coronary syndrome (GR‐ACS) treatment between Aboriginal and Torres Strait Islander and non‐indigenous patients admitted to Royal Darwin Hospital (RDH) with index ACS event. Methods: This retrospective study included index ACS admissions (n = 288) to RDH between January 2016 and June 2017. Outcomes included rates of coronary angiography, percutaneous coronary intervention (PCI), surgical revascularisation, GR‐ACS medications prescribed on discharge and short‐term outcomes (30‐day mortality and ACS readmissions; 12‐month all cardiac‐related readmissions). Results: Two hundred and eighty‐eight patients, including 109 (37.85%) Aboriginal and Torres Strait Islander patients, were included. Compared with non‐indigenous patients, they were younger (median age 48 years vs 60 years; P < 0.01), with a greater burden of comorbidities, including diabetes (39% vs 19%; P < 0.01), smoking (68% vs 35%; P < 0.01) and chronic kidney disease (29% vs 5%; P < 0.01). There were no differences in rates of coronary angiography (98% vs 96%; P = 0.24) or PCI (47% vs 57%; P = 0.12), although there was a trend towards surgical revascularisation in Aboriginal and Torres Strait Islander patients (16% vs 8%; P = 0.047). There were no differences in 30‐day mortality (1.8% vs 1.7%; P = 0.72), 12‐month ACS readmissions (7% vs 4%; P = 0.20) or 12‐month cardiac‐related readmissions (7% vs 13%; P = 0.11). Conclusions: Aboriginal and Torres Strait Islander patients received similar inpatient ACS care and secondary prevention medication at discharge, with similar short‐term mortality outcomes as non‐indigenous patients. While encouraging, these outcomes may not persist long term. Further outcomes research is required, with differences compelling consideration of other primary and secondary prevention contributors.

Hutchinson–Gilford progeria syndrome is an extremely rare genetic disease caused by a de novo mutation in the LMNA gene, leading to an accumulation of a form of Lamin A, called Progerin, which results in a typical phenotype and a marked decrease in life expectancy, due to early atherosclerosis and cardiovascular disease. We report the case of a fourteen-year-old Chinese boy with Hutchinson–Gilford progeria syndrome admitted to the emergency room because of precordial pain. Physical examination showed tachycardia 130 beats/min and arterial hypertension: 170/120 mmHg, normal respiratory rate, no neurological impairment; ECG evidenced sinus tachycardia, left ventricular hypertrophy, horizontal ST-segment depression in I, aVL, II, III, aVF leads, and V4–V6 and ST-segment elevation in aVR and V1 leads. Echocardiography highlighted preserved global left ventricular function with concentric hypertrophy, altered diastolic flow pattern, mitral valve insufficiency, and minimal aortic regurgitation. Blood tests evidenced an increase in high-sensitivity troponin T level (335 pg/mL). NSTEMI diagnosis was performed, and the patient was admitted to the intensive care unit. A coronary CT angiography showed a severe obstruction of the common trunk of the left coronary artery, for which an urgent percutaneous coronary intervention (PCI) was proposed. A selective coronary angiography imaged complete chronic occlusion of the left main coronary artery as well as severe stenosis at the origin of a very enlarged right coronary artery that vascularized the left coronary artery through collaterals. Afterwards, the right coronary artery was probed using an Amplatz right (AR1) guiding catheter, through which a large 3.5 mm drug-eluting coronary stent (Xience Sierra, Abbott, Abbott Park, IL, USA) was implanted. At the end of the procedure, no residual stenosis was imaged and improved vascularization of the left coronary artery distribution segments was observed. Dual antiplatelet therapy (DAPT) consisting of aspirin (75 mg daily) and clopidogrel (37.5 mg daily) and anti-hypertensive therapy were started. At the one-year follow-up, the patient had not reported any occurrence of anginal chest pain. [ABSTRACT FROM AUTHOR]

BACKGROUND Acute coronary syndrome (ACS) is linked to a range of in-hospital complications, and age is recognized as risk factor for adverse events. Discrepancies between physiological and chronological age are explained by frailty. However, the relationship between frailty and in-hospital complications is not clear. METHODS Assessment of frailty in patients was carried out using the FRAIL scale. In-hospital complications assessed in- cluded, bleeding, infection, arrhythmia, acute kidney injury (AKI), delirium, stroke/transient ischemic attack (TIA), liver injury, hypoglycemia, length of stay in the cardiac care unit (CCU). RESULTS Of the 174 patients, frailty was identified in 39.1% and pre-frailty in 29.9%. Frailty was associated with a higher in- cidence of all types of bleeding (frail vs. robust: 45.5% vs. 16.7%, P < 0.001) and infection (54.4% vs. 11.1%, P < 0.001), including pneumonia/lower respiratory tract infections (LRTI) and urinary tract infections (UTI). Incidence of antibiotic therapy (52.9% vs. 13.0%, P < 0.001), atrial fibrillation (AF) (47.1% vs. 9.3%, P < 0.001), AKI (57.3% vs. 20.4%, P < 0.001), delirium (52.9% vs. 3.7%, P < 0.001), liver injury, were higher in frail patients (17.6% vs. 0, P = 0.001), whilst their length of stay in the CCU was longer (4 days (2-6.5) vs. 2 days (2-3), P < 0.001). Infections, pneumonia/LRTI, antibiotic therapy during hospitalization, the incidence of AF and liver injury were more often in patients with pre-frailty compared to the robust group. After adjustment for potential confoun- ders, frailty remained independently associated with an increased risk of infection (OR: 3.3 [1.6-7.0]), including pneumonia/ LRTI (OR: 2.5 [1.1-5.8]) and UTI (OR: 4.8 [1.8-12.5]). Frail individuals had an increased requirement for antibiotic therapy (OR: 3.9 [1.9-8.1]), and greater risk of AF (OR: 3.5 [1.3-9.3]), AKI (OR: 2.6 [1.2-5.3]) delirium (OR: 11.7 [4.8-28.7]), as well as having to stay longer in the CCU (> 3 days) (OR: 3.7 [1.9-7.3]).

Sexual health education (SHE) is an important rehabilitation component for acute coronary syndrome (ACS) survivors but is not routinely provided. This study's purpose was to explore healthcare providers' experiences of providing SHE to ACS survivors in cardiac rehabilitation programs to identify best practices. This qualitative study used convenience sampling and an interpretive descriptive design. Inclusion criteria were a healthcare provider employed within a cardiac rehabilitation program in a Western Canadian province. Eight cardiac rehabilitation healthcare providers volunteered to participate. The first author conducted semi-structured, digitally recorded interviews that were transcribed verbatim. The interviews were guided by a semi-structured interview guide anchored in the strengths-based, sex positive guiding frameworks. A reflective journal and socio-demographic forms served as additional data sources. Data were analyzed using open, axial, and selective coding as well as constant comparative analysis. Credibility was ensured through peer-reviewed evaluation criteria. Eight healthcare providers participated in the study. Participants equated sexuality and sexual health with physical activity and physical health. Findings identified philosophical perspectives and several barriers and facilitators that impact SHE provision. Participants offered strategies that may be used in practice and their recommendations provide a beginning foundation to improve cardiac rehabilitation programs and the health of ACS survivors. Healthcare providers in cardiac rehabilitation programs described their SHE experiences as "just think of it as sexercise." Facilitation of SHE is important as previous studies found that SHE may reduce fear, depression, and anxiety and increase the return to sexual activity among ACS survivors. Sexual health doesn't need to be a taboo topic. Approach sexual health conversations by thinking of it as "sexercise". Don't let silos stop sexual health education – talk to your coworkers and patients about sexual health. Knowledge about sexual health, timing of sexual health education, and communication between care providers and patients are important factors in delivery of sexual health education.

Objective: Many patients presenting with suspected acute coronary syndrome (ACS) have high-sensitivity cardiac troponin (hs-cTn) concentrations between rule-in and rule-out thresholds and hence need serial testing, which is time consuming. The Prospective RandOmised Trial of Emergency Cardiac Computerised Tomography (PROTECCT) assessed the utility of coronary CT angiography (CCTA) in patients with suspected ACS, non-ischaemic ECG and intermediate initial hs-cTn concentration.Methods: Patients were randomised to CCTA-guided management versus standard of care (SOC). The primary outcome was hospital length of stay (LOS). Secondary outcomes included cost of in-hospital stay and major adverse cardiac events (MACE) at 12 months of follow-up. Data are mean (SD); for LOS harmonic means, IQRs are shown.Results: 250 (aged 55 (14) years, 25% women) patients were randomised. Harmonic mean (IQR) LOS was 7.53 (6.0-9.6) hours in the CCTA arm and 8.14 (6.3-9.8) hours in the SOC arm (p=0.13). Inpatient cost was £1285 (£2216) and £1108 (£3573), respectively, p=0.68. LOS was shorter in the CCTA group in patients with <25% stenosis, compared with SOC; 6.6 (5.6-7.8) hours vs 7.5 (6.1-9.4) hours, respectively; p=0.021. More referrals for cardiology outpatient clinic review and cardiac CT-related outpatient referrals occurred in the SOC arm (p=0.01). 12-month MACE rates were similar between the two arms (7 (5.6%) in the CCTA arm and 8 (6.5%) in the SOC arm-log-rank p=0.78).Conclusions: CCTA did not lead to reduced hospital LOS or cost, largely because these outcomes were influenced by the detection of ≥25% grade stenosis in a proportion of patients.Trial Registration Number: NCT03583320.

Background: Women are more likely to delay medical help-seeking for ACS symptoms. Understanding patients' experience of the symptoms and their response is essential in improving help-seeking behaviors and timely diagnosis and treatment for ACS. This study aimed to explore women's experience of ACS, their response to the symptoms, and treatment-seeking decisions.Methods: This qualitative descriptive study was conducted in a tertiary referral specialized heart hospital affiliated with Tabriz University of Medical Sciences, Iran. Participants included 39 women who had experienced ACS for the first time.Results: Four main themes emerged from the analysis of interview transcripts: (1) the onset of symptoms, (2) the types of symptoms, (3) response to symptoms and (4) arriving at the hospital. These themes and associated sub-themes explained women's experience of ACS symptoms, their response to the symptoms, and decision to seek medical help.Conclusions: This study identified and discussed factors contributing to the prehospital delay in women and their decision-making to seek medical care for ACS symptoms. The results are consistent with previous research indicating that ACS symptoms in women are somewhat different from men, and women tend to underestimate their symptoms and attribute them to non-cardiac causes. Women should be supported to develop awareness and understanding of ACS symptoms and appreciate the importance of early treatment-seeking in the disease outcomes. [ABSTRACT FROM AUTHOR]

Background and Aim Of the Study: The widespread use of noninvasive/invasive coronary imaging increased the probability of recognition of coronary aneurysms. Left main coronary aneurysms (LMCA), though rare, are potentially life-threatening but in the absence of controlled studies, guidelines do not provide any specific recommendation for their management. We, therefore, aimed to investigate the epidemiology, clinical presentation, therapeutic strategies, and prognostic implication of LMCA.Methods: A systematic review of the literature was performed to retrieve all the reported cases of LMCA as of December 2021, which were summarized and classified according to their etiology, clinical presentation, and therapeutic management.Results: Out of 1997 works retrieved, 180 studies were analyzed, describing 209 LMCA cases (aged 51 ± 19 years, 68% males). Atherosclerosis was the most common etiology (40%), followed by inflammatory (12%), congenital (9%), or degenerative (6%) conditions. Stable angina (43%) and acute coronary syndromes (32%) were more often the first clinical manifestations, while 29 (14%) LMCA were incidental findings. Most cases were treated surgically (53%), while percutaneous intervention was rarely adopted (7%). Data about antithrombotic therapies were scarce and heterogeneous. Finally, when longitudinal data were reported (n = 81), LMCA resulted associated with a severe prognosis, with a 15% mortality over an 8-month median follow-up.Conclusions: LMCA are most frequently, but not exclusively, caused by advanced atherosclerosis. Irrespective of their etiology and clinical presentation, LMCA may be associated with high short-term mortality. In absence of controlled studies, a careful evaluation of each case is warranted to optimize therapeutic strategies. [ABSTRACT FROM AUTHOR]

Background: In patients with prior coronary artery bypass graft surgery (CABG), acute coronary syndrome (ACS) is not uncommon. This study investigated treatment strategy and compared clinical outcomes for native, graft and absent culprit lesions.Methods: Single-center retrospective cohort study. From July 2010 to July 2019, 642 consecutive ACS patients with prior CABG were screened for eligibility. The primary endpoint was major adverse cardiovascular events (MACE) at 1 year, a composite of all-cause mortality, myocardial infarction, stroke and ischemia-driven revascularization.Results: A total of 549 patients were included, with 215 (39.2 %) having native culprits, 256 (46.6 %) graft culprits and 78 (14.2 %) no clear culprits. Patients with native culprits were treated with native PCI in 94.0 %, re-CABG in 0.9 % and optimal medical therapy (OMT) in 5.1 %. Patients with graft culprits were treated with native PCI in 14.1 %, graft PCI in 81.2 %, re-CABG in 0.8 % and OMT in 3.9 %. All patients without a clear culprit received OMT. The cumulative incidence of 1-year MACE was 24.7 % for native vs 26.2 % for graft vs 21.8 % for absent culprits. Kaplan-Meier curves did not differ significantly. In patients with graft culprit, no significant difference in 1-year MACE was observed between native PCI and graft PCI (30.6 % vs 25.5 %, p = 0.36).Conclusions: This retrospective study shows that in ACS patients with prior CABG, MACE occurred frequently and was comparable for native, graft and absent culprits. Native PCI as treatment strategy for patients with a graft culprit was relatively common, with no significant difference in MACE as compared to graft PCI. [ABSTRACT FROM AUTHOR]

According to the Global Burden of Disease study, in 2019, there were an estimated 275.2 million cases of cardiovascular disease (CVD) in women worldwide. Although there was a decrease in the global age-standardised prevalence of CVD in women between 1990 and 2010 (-5.8%), there has been a slight increase (1.0%) since 2010. There were an estimated 6.10 million deaths from CVD in women in 1990, rising to 8.94 million in 2019. Hospital admissions of young women with acute myocardial infarction (AMI) steadily increased from 27% in 1995-1999 to 32% in 2010-2014. Women with AMI compared with men are less likely to receive guideline-indicated pharmacological (aspirin 93.4% vs 94.7%, P2Y12 inhibitors 79.3% vs 86.1% and statins 73.7% vs 77.5%) and revascularisation treatments (angiography (adjusted OR (aOR) 0.71), percutaneous coronary intervention (aOR 0.73)). Women represent <39% of clinical cardiovascular trial participants between 2010 and 2017. Major factors of under-representation in studies included concerns about the burden of participation on health and time. Women were more likely than men to document caring responsibilities as reasons for not participating in a clinical trial. Current clinical practice guidelines recommending risk stratification to guide the appropriateness of an invasive strategy in the context of acute coronary syndrome (ACS) may not be applicable to women given lack of studies specifically evaluating women using contemporary treatment strategies. In our review, we identify significant limitations in the evidence base for the best care of women with ACS, emphasising the need for well-designed clinical trials specifically recruiting women.

Background: Oral activated factor XI (FXIa) inhibitors may modulate coagulation to prevent thromboembolic events without substantially increasing bleeding. We explored the pharmacodynamics, safety, and efficacy of the oral FXIa inhibitor asundexian for secondary prevention after acute myocardial infarction (MI).Methods: We randomized 1601 patients with recent acute MI to oral asundexian 10, 20, or 50 mg or placebo once daily for 6 to 12 months in a double-blind, placebo-controlled, phase 2, dose-ranging trial. Patients were randomized within 5 days of their qualifying MI and received dual antiplatelet therapy with aspirin plus a P2Y12 inhibitor. The effect of asundexian on FXIa inhibition was assessed at 4 weeks. The prespecified main safety outcome was Bleeding Academic Research Consortium type 2, 3, or 5 bleeding comparing all pooled asundexian doses with placebo. The prespecified efficacy outcome was a composite of cardiovascular death, MI, stroke, or stent thrombosis comparing pooled asundexian 20 and 50 mg doses with placebo.Results: The median age was 68 years, 23% of participants were women, 51% had ST-segment-elevation MI, 80% were treated with aspirin plus ticagrelor or prasugrel, and 99% underwent percutaneous coronary intervention before randomization. Asundexian caused dose-related inhibition of FXIa activity, with 50 mg resulting in >90% inhibition. Over a median follow-up of 368 days, the main safety outcome occurred in 30 (7.6%), 32 (8.1%), 42 (10.5%), and 36 (9.0%) patients receiving asundexian 10 mg, 20 mg, or 50 mg, or placebo, respectively (pooled asundexian versus placebo: hazard ratio, 0.98 [90% CI, 0.71-1.35]). The efficacy outcome occurred in 27 (6.8%), 24 (6.0%), 22 (5.5%), and 22 (5.5%) patients assigned asundexian 10 mg, 20 mg, or 50 mg, or placebo, respectively (pooled asundexian 20 and 50 mg versus placebo: hazard ratio, 1.05 [90% CI, 0.69-1.61]).Conclusions: In patients with recent acute MI, 3 doses of asundexian, when added to aspirin plus a P2Y12 inhibitor, resulted in dose-dependent, near-complete inhibition of FXIa activity without a significant increase in bleeding and a low rate of ischemic events. These data support the investigation of asundexian at a dose of 50 mg daily in an adequately powered clinical trial of patients who experienced acute MI.Registration: URL: https://www.Clinicaltrials: gov; Unique identifier: NCT04304534; URL: https://www.clinicaltrialsregister.eu/ctr-search/search; Unique identifier: 2019-003244-79.

Introduction: Acute coronary syndrome (ACS) patients residing in rural areas are predisposed to higher risk of poor outcomes due to substantial delays in disease management, emphasising the importance of emerging telecardiology technologies in delivering emergency services in such settings. This meta-analysis aimed to investigate the impacts of prehospital telecardiology strategies on the clinical outcomes of rural ACS patients.Methods: A literature search was performed of articles published up to April 2020 through six databases. Included studies were assessed for bias risk using the ROBINS-I tool, and a random-effects model was utilised to estimate effect sizes. Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE).Results: Twelve studies with a total of 3989 patients were included in this review. Prehospital telecardiology in the form of tele-electrocardiography (tele-ECG) enabled prompt diagnosis and triage, resulting in a decreased door-to-balloon (DTB) time (mean difference = -25.53 minutes, 95% confidence interval (CI) -36.08 to -14.97 minutes; I2 = 98%), as well as lower in-hospital mortality (odds ratio (OR) = 0.57, 95% CI 0.36-0.92) and long-term mortality (OR = 0.52, 95% CI 0.39-0.69) rates, both with negligible heterogeneity (I2 = 0%). GRADE assessment yielded very low to moderate certainty of evidence.Conclusion Prehospital tele-ECG appeared to be an effective and worthwhile approach in the management of rural ACS patients, as shown by moderate quality evidence on lower long-term mortality. Given the uncertainties of the evidence quality on DTB time and in-hospital mortality, future studies with a higher quality of evidence are required to confirm our findings. [ABSTRACT FROM AUTHOR]

Rationale: Obstructive sleep apnea (OSA) is prevalent in patients with acute coronary syndrome (ACS) and is a cause of secondary hypertension. Objectives: To explore the long-term effects of OSA and continuous positive airway pressure (CPAP) treatment on blood pressure (BP) in patients with ACS. Methods:Post hoc analysis of the ISAACC study (Continuous Positive Airway Pressure in Patients with Acute Coronary Syndrome and Obstructive Sleep Apnea; NCT01335087) included 1,803 patients admitted for ACS. Patients with OSA (apnea-hypopnea index [AHI], ⩾15 events/h) were randomly assigned to receive either CPAP or usual care and were seen in follow-up for 1-5 years. Office BP was determined at each visit. Results: We included 596 patients without OSA, 978 patients in the usual care or poor CPAP adherence group, and 229 patients in the good CPAP adherence group. At baseline, 52% of the patients were diagnosed with hypertension. Median (25th to 75th percentile) age and body mass index were 59 (52.0 to 67.0) years and 28.2 (25.6 to 31.2) kg/m2, respectively. After a median (25th to 75th percentile) follow-up of 41.2 (18.3 to 59.6) months, BP changes were similar in the OSA and non-OSA groups. However, we observed an increase in BP in the third tertile of the AHI (AHI, >40 events/h), with a maximum difference in mean BP of +3.3 mm Hg at 30 months. Patients with OSA with good CPAP adherence (⩾4 h/night) reduced mean BP after 18 months compared with patients with usual care/poor CPAP adherence, with a maximum mean difference (95% confidence interval) of -4.7 (-6.7 to -2.7) mm Hg. In patients with severe OSA, we observed a maximum mean difference of -7.1 (-10.3 to -3.8) mm Hg. Conclusions: In patients with ACS, severe OSA is associated with a long-term increase in BP, which is reduced by good CPAP adherence.

Limited clinical studies are available on early exercise-based cardiac rehabilitation in elderly acute coronary syndrome (ACS) patients. To evaluate the effect of aerobic exercise on exercise capacity and quality of life (QoL) in such patients. Seventy elderly patients with ACS undergoing percutaneous coronary intervention in Zhejiang Hospital during August 2016-June 2017 were randomly divided into the control (n = 35) or cardiac rehabilitation group (CR, n = 35). The control group was treated with standard medical treatments without exercise, whereas the CR group was treated with standard medical treatments and exercise-based cardiac rehabilitation. General information, cardiopulmonary exercise test (CPET) results, responses to QoL and mental health questionnaires, and clinical outcomes and safety were collected. The CR group safely finished CPET and the 12-week exercise-based cardiac rehabilitation. After the 12-week intervention, the CR group showed significant differences in maximal oxygen uptake (VO2max) and greater improvements in VO2max, compared with the control group. The CR group showed statistically significant differences in QoL and mental health compared with the control group. CPET-based exercise in cardiac rehabilitation can safely increase exercise capacity and QoL in such patients. [ABSTRACT FROM AUTHOR]

Background: The use of rotational atherectomy (RA) in percutaneous coronary intervention (PCI) of acute coronary syndrome (ACS) is considered relatively contraindicated. There have been several observational studies showing RA use in ACS, however, no systemic studies have been undertaken. We sought to evaluate the feasibility and outcomes of RA PCI in ACS by performing a meta-analysis.Methods: We searched PUBMED, EMBASE, CINAHL, and Cochrane Central Register of Clinical Trials for any studies that evaluated the role of RA PCI in ACS. The outcomes analyzed were all-cause mortality, cardiac mortality, short and long-term major adverse cardiac events (MACE), procedural complications and cardiac perforations.Results: There was a total of 8 retrospective studies with a total population of 1237 with a median follow up of 23 months. The median age of the included patient was 73. Angiographic success rate was 97.4%. The rate of all-cause mortality and cardiac mortality were 5% (range 1-12%, p < 0.001, I2 = 92%) and 2% (range 0-5%, P = 0.03, I2 = 58%) respectively. In-hospital MACE and long-term MACE were 7% (range 3-13%, p < 0.001, I2 = 87%) and 29% (range 21-37%, p = 0.21, I2 = 34%) respectively. The incidence of total procedural complications was noted to be 7% (range 2-14%, p < 0.001, I2 = 90%). Rate of perforation was 1% (range 0-1%, p = 0.9, I2 = 0%).Conclusion: Our results show that RA PCI is feasible in ACS with comparable procedural complications and short-term MACE, but with a higher long-term MACE rate compared to RA PCI in routine cases.

Background: The Global Registry of Acute Coronary Events (GRACE) 2.0 score was developed and validated in predominantly male patient populations. We aimed to assess its sex-specific performance in non-ST-segment elevation acute coronary syndromes (NSTE-ACS) and to develop an improved score (GRACE 3.0) that accounts for sex differences in disease characteristics.Methods: We evaluated the GRACE 2.0 score in 420 781 consecutive patients with NSTE-ACS in contemporary nationwide cohorts from the UK and Switzerland. Machine learning models to predict in-hospital mortality were informed by the GRACE variables and developed in sex-disaggregated data from 386 591 patients from England, Wales, and Northern Ireland (split into a training cohort of 309 083 [80·0%] patients and a validation cohort of 77 508 [20·0%] patients). External validation of the GRACE 3.0 score was done in 20 727 patients from Switzerland.Findings: Between Jan 1, 2005, and Aug 27, 2020, 400 054 patients with NSTE-ACS in the UK and 20 727 patients with NSTE-ACS in Switzerland were included in the study. Discrimination of in-hospital death by the GRACE 2.0 score was good in male patients (area under the receiver operating characteristic curve [AUC] 0·86, 95% CI 0·86-0·86) and notably lower in female patients (0·82, 95% CI 0·81-0·82; p<0·0001). The GRACE 2.0 score underestimated in-hospital mortality risk in female patients, favouring their incorrect stratification to the low-to-intermediate risk group, for which the score does not indicate early invasive treatment. Accounting for sex differences, GRACE 3.0 showed superior discrimination and good calibration with an AUC of 0·91 (95% CI 0·89-0·92) in male patients and 0·87 (95% CI 0·84-0·89) in female patients in an external cohort validation. GRACE 3·0 led to a clinically relevant reclassification of female patients to the high-risk group.Interpretation: The GRACE 2.0 score has limited discriminatory performance and underestimates in-hospital mortality in female patients with NSTE-ACS. The GRACE 3.0 score performs better in men and women and reduces sex inequalities in risk stratification.Funding: Swiss National Science Foundation, Swiss Heart Foundation, Lindenhof Foundation, Foundation for Cardiovascular Research, and Theodor-Ida-Herzog-Egli Foundation.

Background: Clopidogrel is the most frequently used P2Y12 inhibitor as a component of the dual antiplatelet regimen in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). Prior studies have shown the variable efficacy of clopidogrel due to genotypic differences in the CYP2C19 enzyme function, which converts clopidogrel to its active metabolite. The aim of this meta-analysis is to evaluate the effectiveness of genotype testing-guided P2Y12 inhibitor prescription therapy to patients after PCI for ACS compared to non-genotype guided conventional treatment.Methods: A comprehensive literature search was performed in PubMed, Embase, and Cochrane to identify relevant trials. Summary effects were calculated using a DerSimonian and Laird random-effects model as odds ratio with 95% confidence intervals for all the clinical endpoints.Results: Seven studies with 9617 patients were included. Genotype-guided strategy arm included prasugrel or ticagrelor prescription to patients with loss of function (LOF) of CYP219 alleles (most commonly alleles being *2 and *3) and clopidogrel prescription to those without the LOF allele. The conventional arm included patients treated with clopidogrel without genotype testing. Comparison of genotype arm with conventional arm showed decreased major adverse cardiovascular events (MACE), improved cardiovascular (CV) mortality, and reduced incidence of myocardial infarction (MI) in the genotype arm, and a similar stroke incidence in the two arms. Regarding adverse events, the incidence of stent thrombosis was lower in the genotype arm than the conventional arm.Conclusion: Our analysis illustrates the possible advantages of genotype-guided P2Y12 inhibitor prescription strategy compared to non-genotype-guided strategy with reductions in MACE, CV mortality, MI, and stent thrombosis. This analysis can be used as a stepping stone to conducting further trials determining the efficacy of this treatment strategy in various ACS subtypes. [ABSTRACT FROM AUTHOR]

Background: Antiplatelet therapy is a cornerstone in the secondary prevention of ischemic events following percutaneous coronary intervention (PCI). The new P2Y12 receptor inhibitors prasugrel and ticagrelor have been shown to improve patients' outcomes. Whether or not these drugs have equal efficacy in individuals with or without diabetes is disputed. Furthermore, platelets can be activated by thrombin, which is, at least in part, independent of P2Y12‐mediated platelet activation. Protease‐activated receptor (PAR)‐1 and −4 are thrombin receptors on human platelets. We sought to compare the in vitro efficacy of prasugrel (n = 121) and ticagrelor (n = 99) to inhibit PAR‐mediated platelet aggregation in individuals with type 2 diabetes (prasugrel n = 26, ticagrelor n = 29). Materials and Methods: We compared P2Y12‐, PAR‐1‐ and PAR‐4‐mediated platelet aggregation as assessed by multiple electrode platelet aggregometry between prasugrel‐ and ticagrelor‐treated patients without and with type 2 diabetes who underwent acute PCI. Results: Overall, there were no differences of P2Y12‐, PAR‐1‐ and PAR‐4‐mediated platelet aggregation between prasugrel‐ and ticagrelor‐treated patients. However, both drugs inhibited P2Y12‐mediated platelet aggregation stronger, and thereby to a similar extent in patients with type 2 diabetes than in those without diabetes. There was no correlation between either P2Y12‐, or PAR‐1‐ or PAR‐4‐mediated platelet aggregation and levels of HbA1c or the body mass index (BMI). However, we observed patients with high residual platelet reactivity in response to PAR‐1 and PAR‐4 stimulation in all cohorts. Conclusion: Prasugrel and ticagrelor inhibit P2Y12‐ and PAR‐mediated platelet aggregation in individuals with diabetes to a similar extent, irrespective of HbA1c levels and BMI.

Background: Octogenarians (age ≥ 80 years) with coronary artery disease constitute a high-risk group and the elderly undergoing percutaneous coronary intervention (PCI) are at higher risk of adverse outcomes compared to young patients. In this study, we aimed to describe the outcomes of the elderly with acute coronary syndrome (ACS) who underwent PCI and also to identify the predictors of short-term major adverse cerebrocardiovascular events (MACCE) in octogenarians. Methods: In this registry-based cohort study, we reviewed the data of patients (aged ≥ 65 years) who underwent PCI. Univariate Cox-regression model was used to assess the univariate effects of covariates on mortality and MACCE and multivariate Cox-regression analysis were used to discover MACCE predictors. Results: We reviewed the data of 3332 patients (2722 elderly [65 to 79 years], and 610 octogenarians [ ≥ 80 years]). The cumulative hazard of MACCE was significantly higher in the octogenarian group compared with the younger group (P < 0.001). MACCE in octogenarians presenting with ST-elevation myocardial infarction (STEMI) was significantly higher than those with non-ST-elevation myocardial infarction/Unstable angina (NSTEMI/UA) (P < 0.001); however, the cumulative hazard of mortality was not significantly different between the two groups (P = 0.270). Successful PCI, left main stenosis and estimated glomerular filtration rate (eGFR) were independent predictors of MACCE in octogenarians with ACS. Conclusion: Octogenarians undergoing PCI had a higher rate of MACCE and mortality compared with a younger population. In octogenarians, MACCE in those with STEMI was significantly higher than those with NSTEMI/UA and the mortality trend was similar; however, the 1-year trend was in favor of the STEMI subgroup.

Introduction: P2Y12-inhibitor monotherapy following 1-3 months of dual antiplatelet therapy (DAPT) reduces (major) bleeding without an apparent increase in ischemic events and has therefore emerged as an alternative to 6-12 months of DAPT following percutaneous coronary intervention (PCI). However, there are important differences between the available P2Y12-inhibitors (clopidogrel, prasugrel, and ticagrelor) as agents of choice for P2Y12-inhibitor monotherapy.Areas Covered: This review critically appraises the evidence for P2Y12-inhibitor monotherapy after PCI using either clopidogrel, prasugrel, or ticagrelor. Furthermore, we discuss ongoing trials and future directions for research.Expert Opinion: P2Y12-inhibitor monotherapy following 1-3 months of DAPT is an alternative to 6-12 months of DAPT following PCI. Ticagrelor may be considered the current preferred option due to its reliable effect on platelet reactivity and its predominant use in clinical trials. Prasugrel could serve as a useful substitute for those not tolerating ticagrelor, but more research into prasugrel monotherapy is warranted. Alternatively, clopidogrel can be used, although there are concerns of high platelet reactivity, especially when genotyping and/or platelet function testing are not used. Future research will need to address the minimal duration of DAPT before switching to P2Y12-inhibitor monotherapy and what the optimal antithrombotic therapy beyond 12 months is.

Background: The literature about the safety and feasibility of same-day discharge (SDD) following complex percutaneous coronary intervention (PCI) and in acute coronary syndrome (ACS) is scarce. The economic impact of SDD has not been evaluated in this geographical region. We in the present study evaluated the safety, feasibility, and economic impact of SDD following PCI at a tertiary care centre of north India.Methods: It was a single-centre, non-randomized, prospective study, in which all consecutive PCI patients during the study period of 15 months were evaluated for SDD using a "patient-centred" approach. The patients who were discharged on the next calendar day were included in the next day discharge (NDD) group. The baseline demographic data including coronary risk factors, clinical presentation, and management details were noted for all patients. All patients were followed up for 6 weeks. The Indian health system is only partially insured, hence most of the expendable costs are borne by patients. In the present study, we computed the total societal expenditure of each PCI which includes both the health system costs and the expenditure borne by the patients. A standardized tool and bottoms up costing method were used for recording out-of-pocket expenditure (OOPE) by the patients and health care expenditure respectively.Results: Out of a total of 675 PCI patients, 617 patients were enrolled in the study, and 132/617 (21.39%) patients were discharged the same day. Sixty-five % of patients (86/132) in the SDD cohort and 70% of patients (337/485) in the NDD cohort presented with ACS. Baseline characteristics in the two cohorts were identical. A higher syntax score, greater number of stents, and longer stented segment predicted the NDD. The mean length of stay after PCI in patients with SDD and NDD was 8.71 ± 2.48 and 21.76 ± 2.42 h, respectively. In the SDD group, there were no readmissions or adverse events after discharge till 6 weeks of follow-up. The total mean cost of PCI (health care system and OOPE) for SDD and NDD was Indian Rupees (INR) 129,322.14 [United States dollar (US$) 1810.51] and INR 165500.71 [US$ 2317.01] respectively. An amount of INR 36178.57 (health system cost: INR 10242.76 and OOPE: INR 25935.71 was saved for each SDD. Besides 100 cardiac unit bed days including 85 intensive cardiac care bed days were saved with 21% SDD in the present cohort.Conclusion: Post PCI SDD is safe and feasible in selected ACS/chronic stable angina patients using the "patient-centred" approach. Besides, decreasing OOPE for the patients, SDD also helps in the efficient use of scarce health system resources. [ABSTRACT FROM AUTHOR]

• South Asians have extreme ASCVD risk, necessitating updated recommendations for ACS. • Risk of adverse cardiovascular outcomes after ACS is highest within the first 30 days. • Many patients have persistent hypercholesterolemia and risk after ACS despite statins. • Lipoprotein(a) elevation is prevalent and increases risk of adverse CV outcomes. • The Lipid Association of India recommends earlier aggressive lipid lowering after ACS. Patients with acute coronary syndrome (ACS) have a high risk of subsequent adverse cardiovascular outcomes, particularly within the first 30 days. Although it is well documented that initiation of statin therapy in the setting of ACS improves short- and long-term cardiovascular outcomes, and achievement of lower levels of low density lipoprotein cholesterol (LDL-C) incrementally improves outcomes, many patients with ACS have persistent hypercholesterolemia after discharge from the hospital. This is a missed opportunity that prompted the Lipid Association of India to develop recommendations for earlier initiation of more aggressive LDL-C lowering treatment, particularly for patients of South Asian descent who are well-documented to have earlier onset of more aggressive atherosclerotic cardiovascular disease. The Lipid Association of India recommends individualized aggressive LDL-C goals after ACS, which can be rapidly achieved with high intensity statin therapy and subsequent goal-directed adjunctive treatment with ezetimibe and PCSK9 inhibitors. Improved treatment of hypercholesterolemia achieved within weeks after ACS has the potential to reduce the high rate of morbidity and mortality in these high risk patients.

Background: Coronary vascular function of a chronic coronary total occlusion (CTO) immediately after recanalization is known to be poor and to be partially improved by pre-treatment with loading dose of ticagrelor vs. clopidogrel. It is unknown if this vascular dysfunction is maintained at long-term follow-up and may be improved by 1-year dual antiplatelet therapy (DAPT).Methods: The TIGER is a prospective, open-label, two parallel-group controlled clinical trial, which 1:1 randomized 50 CTO patients to pre-PCI loading dose and subsequent 1-year DAPT with ticagrelor vs. clopidogrel. Coronary blood flow (CBF) under stepwise adenosine infusion was assessed after drug loading dose and at follow-up and compared between the two drug groups, adjusting for time of follow-up.Results: Out of 50 patients with index CBF evaluation, 38 (76%) patients underwent angiographic follow-up (23 and 15 at 1 and 3-year, respectively) and Doppler data was available in 35 (70%). A high CBF area under the curve (AUC), already observed after loading dose in ticagrelor vs. clopidogrel group (p = 0.027), was maintained at follow-up (AUC 34815.22 ± 24,206.06 vs. AUC 22712.47 ± 13,768.95; p = 0.071). Specifically, whereas high ticagrelor loading dose-related CBF was sustained at follow-up (p = 0.933), clopidogrel loading dose-related CBF increased at follow-up (p = 0.039).Conclusion: The TIGER trial showed that DAPT with ticagrelor maintained a non-significantly higher CBF in a recanalized CTO as compared to clopidogrel, whose treated patients exhibit a lower CBF immediately after PCI with a significant increase at follow-up. The clinical value of such sustained high coronary flow should be evaluated in a larger group of patients.Clinical Trial Registration: https://clinicaltrials.gov/ct2/show/NCT02211066 (ClinicalTrials.gov number NCT02211066).

Previous studies reported regional variations in in-hospital acute coronary syndrome (ACS) mortality, but the reasons for that were not clearly defined. We explored whether differences in patient characteristics could explain regional variation. The Improving Care for Cardiovascular Disease in China (CCC)-ACS project is an ongoing national registry and quality improvement project, involving 150 tertiary hospitals from 30 provinces across China. We applied a prediction model that included patient-specific variables to calculate the expected in-hospital mortality. For each province, we reported the observed, expected in-hospital mortality and the risk-adjusted ratio which is based on the observed divided by the expected mortality. From 2014 to 2018, 79 585 ACS patients were enrolled. The average in-hospital mortality was 1.8%. There was a wide variation in the in-hospital mortality among different provinces (0.2-3.9%). Patient characteristics explained part of this variation because of differences in the expected in-hospital mortality (0.7-2.8%). There was a substantial variation in the risk-adjusted ratio among provinces (0.2-3.5), which suggests that the variations in the mortality cannot be completely explained by the differences in patient characteristics. In conclusion, we observed a wide regional variation in mortality for ACS, part of which could be explained by the difference in patient characteristics. [ABSTRACT FROM AUTHOR]

Background: Structured risk-stratification to guide clinician assessment and engagement with evidence-based therapies may reduce care variance and improve patient outcomes for Acute Coronary Syndrome (ACS). The Australian Grace Risk score Intervention Study (AGRIS) explored the impact of the GRACE Risk Tool for stratification of ischaemic and bleeding risk in ACS. While hospitals in the active arm had a higher overall rate of invasive ACS management, there was neutral impact on important secondary prevention prescriptions/referrals, hospital performance measures, myocardial infarction and 12-month mortality leading to early trial cessation. Given the Grace Risk Tool is under investigation internationally, this process evaluation study provides important insights into the possible contribution of implementation fidelity on the AGRIS study findings.Methods: Using maximum variation sampling, five hospitals were selected from the 12 centres enrolled in the active arm of AGRIS. From these facilities, 16 local implementation stakeholders (Cardiology advanced practice nurses, junior and senior doctors, study coordinators) consented to a semi-structured interview guided by the Theoretical Domains Framework. Directed Content Analysis of qualitative data was structured using the Capability/Opportunity/Motivation-Behaviour (COM-B) model.Results: Physical capability was enhanced by tool usability. While local stakeholders supported educating frontline clinicians, non-cardiology clinicians struggled with specialist terminology. Physical opportunity was enhanced by the paper-based format but was hampered when busy clinicians viewed risk-stratification as one more thing to do, or when form visibility was neglected. Social opportunity was supported by a culture of research/evidence yet challenged by clinical workflow and rotating medical officers. Automatic motivation was strengthened by positive reinforcement. Reflective motivation revealed the GRACE Risk Tool as supporting but potentially overriding clinical judgment. Divergent professional roles and identity were a major barrier to integration of risk-stratification into routine Emergency Department practice. The cumulative result revealed poor form completion behaviors and a failure to embed risk-stratification into routine patient assessment, communication, documentation, and clinical practice behaviors.Conclusions: Numerous factors negatively influenced AGRIS implementation fidelity. Given the prominence of risk assessment recommendations in United States, European and Australian guidelines, strategies that strengthen collaboration with Emergency Departments and integrate automated processes for risk-stratification may improve future translation internationally.

Background: Instantaneous wave-free ratio (iFR) is a coronary physiology index used to assess the severity of coronary artery stenosis to guide revascularization. iFR has previously demonstrated noninferior short-term outcome compared to fractional flow reserve (FFR), but data on longer-term outcome have been lacking.Objectives: The purpose of this study was to investigate the prespecified 5-year follow-up of the primary composite outcome of all-cause mortality, myocardial infarction, and unplanned revascularization of the iFR-SWEDEHEART trial comparing iFR vs FFR in patients with chronic and acute coronary syndromes.Methods: iFR-SWEDEHEART was a multicenter, controlled, open-label, registry-based randomized clinical trial using the Swedish Coronary Angiography and Angioplasty Registry for enrollment. A total of 2,037 patients were randomized to undergo revascularization guided by iFR or FFR.Results: No patients were lost to follow-up. At 5 years, the rate of the primary composite endpoint was 21.5% in the iFR group and 19.9% in the FFR group (HR: 1.09; 95% CI: 0.90-1.33). The rates of all-cause death (9.4% vs 7.9%; HR: 1.20; 95% CI: 0.89-1.62), nonfatal myocardial infarction (5.7% vs 5.8%; HR: 1.00; 95% CI: 0.70-1.44), and unplanned revascularization (11.6% vs 11.3%; HR: 1.02; 95% CI: 0.79-1.32) were also not different between the 2 groups. The outcomes were consistent across prespecified subgroups.Conclusions: In patients with chronic or acute coronary syndromes, an iFR-guided revascularization strategy was associated with no difference in the 5-year composite outcome of death, myocardial infarction, and unplanned revascularization compared with an FFR-guided revascularization strategy.

Objective: We investigated which factors predict late presentation (LP) to the emergency department (ED) in patients with non-traumatic chest pain (CP).Methods: All CP cases attended at a single ED (2008-2017) were included. LP was considered if time from CP onset to ED arrival was>6 h. We analyzed associations between 42 patient/CP-related characteristics and LP in the whole cohort and in patients with CP due to acute coronary syndrome (ACS).Results: The cohort included 25,693 cases (LP=50.6%; ACS=19.0%). Twenty factors were associated with LP, and 8 were also found in patients with ACS: CP of short-duration, aggravated by exertion or breathing/movement, undulating or recurrent CP increased the risk of LP, whereas CP accompanied by diaphoresis, irradiated to the throat, and chronic treatment with nitrates decreased the risk of LP. Exertional and recurrent CP were associated with both, LP and ACS.Conclusion: Some characteristics, mainly CP-related, may lead to LP to the ED. CP aggravated by exercise and recurrent CP were associated with both LP and a final diagnosis of ACS.Practice Implications: Patient educational initiatives should consider these two features as potential warnings for ACS and thereby encourage patients to seek early medical consultation.

Introduction: Trials investigating aspirin omission in patients taking oral anticoagulation (OAC) after percutaneous coronary intervention (PCI) or acute coronary syndrome (ACS) were not powered to assess rates of major bleeding or ischemic events.Methods: We performed an updated meta-analysis and network analysis of randomized trials comparing treatment with or without aspirin in patients taking OAC and a P2Y12-inhibitor after PCI or ACS. The primary outcome was TIMI major bleeding.Results: Five trials enrolling 11,542 patients allocated to antithrombotic regimens omitting (n = 5795) or including aspirin (n = 5747) were included. Aspirin omission was associated with a lower risk of TIMI major bleeding (RR = 0.56, 95% CI [0.44-0.71]; P < 0.001) but a trend towards a higher risk of MI (RR = 1.21, 95% CI [0.99-1.47]; P = 0.06), which was significantly higher when only non-vitamin K antagonist OAC (NOAC)-based trials were considered (Pinteraction = 0.02). The risk of stent thrombosis was comparable with both strategies (RR = 1.29, 95% CI [0.87-1.90]; P = 0.20), with a trend towards a higher risk of ST with aspirin omission when only NOAC-based trials were considered (Pinteraction = 0.06). Risks of stroke and death were similar with both strategies. Network meta-analysis ranked dabigatran (low dose) without aspirin as the best strategy for bleeding reduction (P-score = 0.86) and apixaban with aspirin as the best strategy for MI reduction (P-score = 0.66).Conclusions: In patients taking OAC after PCI or ACS, aspirin omission is associated with a lower risk of TIMI major bleeding, with a numerically increased risk of MI, which is statistically significant when only NOAC-based trials are considered. This supports individualization of the treatment regimen based on patient risk. [ABSTRACT FROM AUTHOR]

Aim: To investigate the optimal treatment strategy in patients older than 80 years with non‐ST‐segment elevation acute coronary syndrome (NSTE‐ACS). Methods: All published randomized, placebo‐controlled trials (RCTs) reporting on comparisons between invasive and conservative strategies for patients aged 80 years or older with NSTE‐ACS were identified. The literature search was performed using PubMed, EMBASE, Cochrane Library, and the ISI Web of Science, from their establishment to July 2021 with no language restriction. The pooled risk ratios (RRs) with 95% confidence intervals (CI) for dichotomous outcomes were calculated. Results: Three RCTs involving a total of 893 cases met the inclusion criteria. Compared with the conservative group, the invasive strategy could significantly improve the incidence rate of composite endpoint (I2 = 21.9%; RR 0.727, 95% CI 0.619 to 0.855, P < 0.001), recurrent myocardial infarction (MI) (I2 = 0.0%; RR 0.585, 95% CI 0.441 to 0.776, P < 0.001) and revascularization (I2 = 0.0%; RR 0.239, 95% CI 0.126 to 0.455, P < 0.001). However, no benefits were observed on outcomes of all‐cause death (I2 = 0.0%; RR 0.888, 95% CI 0.681 to 1.160, P = 0.384), cardiac death (I2 = 0.0%; RR 0.769, 95% CI 0.412 to 1.433, P = 0.408) and stroke (I2 = 0.0%; RR 0.778, 95% CI 0.392 to 1.543, P = 0.473). The major bleeding events were comparable between the two groups (I2 = 0.0%; RR 1.582, 95% CI 0.622 to 4.025, P = 0.336). Conclusions: Compared with a conservative strategy, the invasive treatment could reduce the incidence of composite endpoint, recurrent MI, and revascularization in the very elderly with NSTE‐ACS. However, no benefits were observed on mortality. Geriatr Gerontol Int 2022; 22: 36–41. [ABSTRACT FROM AUTHOR]

Liver cirrhosis (LC) is becoming increasingly common among patients presenting with acute coronary syndromes (ACS) and is associated with significant cardiovascular morbidity and mortality. Management of such patients is complicated by LC related complications. Literature is scarce on the safety of antithrombotic regimens and invasive strategies for ACS in patients with LC, especially those undergoing liver transplant evaluation. Recently there has been evidence that cirrhosis is an independent risk factor for adverse outcomes in ACS. As patients with LC are generally excluded from large randomized trials, definitive guidelines for the management of ACS in this particular cohort are lacking. Many antithrombotic drugs require either hepatic activation or clearance; hence, an accurate assessment of hepatic function is required prior to initiation and dose adjustment. Despite a demonstrated survival benefit of optimal medical therapy and invasive revascularization techniques in LC patients with ACS, both strategies are currently underutilized in this population. This review aims to present currently available data and provide a practical, clinically oriented approach for the management of ACS in LC. Randomized clinical trials in LC patients with ACS are the need of the hour to further refine their management for favorable outcomes. [ABSTRACT FROM AUTHOR]

We aimed to explore reasons for delay in seeking healthcare among women with acute coronary syndrome (ACS) for the first time from urban and rural areas in Jordan. A qualitative descriptive design was used through face-to-face interviews with 33 women. Themes that explained why women delayed seeking healthcare when experiencing ACS were: Knowledge deficit about coronary artery disease; the effect of disparity in healthcare services on women decision; and life priorities of women during the ACS attack. Educational needs should be addressed based on variations in both areas. Supplemental data for this article is available online at https://doi.org/10.1080/07399332.2021.1955889.

Background: Thin-strut biodegradable polymer sirolimus-eluting stents (BP-SES) have been shown to reduce target lesion failure (TLF) at one-year follow-up compared with durable polymer everolimus-eluting stents (DP-EES) among patients with acute coronary syndrome (ACS). The long-term clinical benefits of thin-strut BP-SES over DP-EES in ACS patients after complete degradation of the polymer coating remain uncertain.Methods: We performed a post-hoc subgroup analysis of ACS patients included into the BIOSCIENCE randomized trial (NCT01443104). The primary endpoint was target lesion failure (TLF), a composite of cardiac death, target-vessel myocardial infarction or clinically indicated target lesion revascularization, at 5 years.Results: Among 2119 patients enrolled between March 2012 and May 2013, 1131 (53%) presented with ACS. The 5-year cumulative incidence of TLF was significantly lower in patients with ACS compared to chronic coronary syndrome [16.5% vs. 22.9%; rate ratio (RR), 0.69; 95% confidence interval (CI), 0.57-0.85; p < 0.001]. At 5 years, TLF occurred similarly in ACS patients treated with BP-SES and DP-EES (16.9% vs. 16.0%; RR, 1.04; 95% CI, 0.78-1.41; p = 0.78). The individual components of the primary endpoint did not differ between ACS patients treated with BP-SES or DP-EES at 5 years. Overall, there was no interaction between clinical presentation and treatment effect.Conclusions: In a subgroup analysis of the BIOSCIENCE trial, we found no difference in long-term outcomes between ACS patients treated with BP-SES or DP-EES at 5 years.

Background: Elderly patients with acute coronary syndromes (ACS) are at higher risk for complications and health care resources expenditure. No previous study has assessed the specific contribution of frailty and other geriatric syndromes to the in-hospital economic cost in this setting.Method: Unselected patients with ACS aged ≥75 years were prospectively included. A comprehensive geriatric assessment was performed during hospitalisation. Hospitalisation-related cost per patient was calculated with an analytical accountability method, including hospital stay-related expenditures, interventions, and consumption of devices. Expenditure was expressed in Euros (2019). The contribution of geriatric syndromes and clinical factors to the economic cost was assessed with a linear regression method.Results: A total of 194 patients (mean age 82.6 years) were included. Mean length of hospital stay was 11.3 days. The admission-related economic cost was €6,892.15 per patient. Most of this cost was attributable to hospital length of stay (77%). The performance of an invasive strategy during the admission was associated with economic cost (p=0.008). Of all the ageing-related variables, comorbidity showed the most significant association with economic cost (p=0.009). Comorbidity, disability, nutritional risk, and frailty were associated with the hospital length of stay-related component of the economic cost. The final predictive model of economic cost included age, previous heart failure, systolic blood pressure, Killip class at admission, left main disease, and Charlson index.Conclusions: Management of ACS in elderly patients is associated with a significant economic cost, mostly due to hospital length of stay. Comorbidity mostly contributes to in-hospital resources expenditure, as well as the severity of the coronary event. [ABSTRACT FROM AUTHOR]

Objectives: Our study aimed to determine the prevalence and prognosis of acute coronary syndrome with non-obstructive coronary artery (ACS-NOCA) in patients with hypertrophic cardiomyopathy (HCM).Methods and Results: We enrolled a total of 200 consecutive patients with HCM over a 139-month period from 2002 to 2013. The study found that 28 patients (14% of overall patients, 51% of patients with ACS) had ACS-NOCA, and 18 patients (9% of overall patients, 86% of patients with acute MI) had MINOCA as initial clinical presentations. The highest prevalence of non-obstructive coronary artery disease (NOCA) in patients with HCM was found in acute ST-elevation myocardial infarction (STEMI) (100%), followed by non-STEMI (82%), and unstable angina (29%). Patients with ACS-NOCA had more frequent ventricular tachycardia and lower resting left ventricular (LV) outflow tract gradients than those with no ACS-NOCA (p < 0.05 for all). The ACS-NOCA group had a lower probability of HCM-related death compared with the no ACS-NOCA group and the significant coronary artery disease (CAD) group (p-log-rank = 0.0018).Conclusions: MINOCA or ACS-NOCA is not an uncommon initial presentation (prevalence rate 9-14%) in patients with HCM. NOCA was highly prevalent (51-86%) in patients with HCM presenting with ACS and had a favorable prognosis. Our findings highlight as a reminder that in an era of rapid reperfusion therapy, ACS in patients with HCM is not only a result of obstructive epicardial CAD, but also stems from the complex cellular mechanisms of myocardial necrosis.
