Abstract
INTRODUCTION Clinical assessment is pivotal in diagnosing acute coronary syndrome. Our study aimed to identify clinical characteristics predictive of major adverse cardiac events (MACE) in an Asian population and to derive a risk score for MACE. METHODS Patients presenting to the emergency department (ED) with chest pain and non-diagnostic 12-lead electrocardiograms were recruited. Clinical history was recorded in a predesigned template. Random glucose and direct low-density lipoprotein measurements were taken, in addition to serial troponin. We derived the age, coronary risk factors (CRF), sex and symptoms (ACSS) risk score based on multivariate analysis results, considering age, CRF, sex and symptoms and classifying patients into very low, low, moderate and high risk for MACE. Comparison was made with the ED Assessment of Chest Pain Score (EDACS) and the history, electrocardiogram, age, risk factors, troponin (HEART) score. We also modified the HEART score with the CRF that we had identified. The outcomes were 30-day and 1-year MACE. RESULTS There were a total of 1689 patients, with 172 (10.2%) and 200 (11.8%) having 30-day and 1-year MACE, respectively. Symptoms predictive of MACE included central chest pain, radiation to the jaw/neck, associated diaphoresis, and symptoms aggravated by exertion and relieved by glyceryl trinitrate. The ACSS score had an area under the curve of 0.769 (95% confidence interval [CI]: 0.735-0.803) and 0.760 (95% CI: 0.727-0.793) for 30-day and 1-year MACE, respectively, outperforming EDACS. Those in the very-low-risk and low-risk groups had <1% risk of 30-day MACE. CONCLUSION The ACSS risk score shows potential for use in the local ED or primary care setting, potentially reducing unnecessary cardiac investigations and admission.

Analyzing predictors of in-hospital mortality in patients with acute ST-segment elevation myocardial infarction using an evolved machine learning approach. Comput Biol Med 2024; 170:107950. [PMID: 38237236 DOI: 10.1016/j.compbiomed.2024.107950] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 12/08/2023] [Accepted: 01/01/2024] [Indexed: 02/28/2024]
Abstract
Acute ST-segment elevation myocardial infarction (STEMI) is a severe cardiac ailment characterized by the sudden complete blockage of a portion of the coronary artery, leading to the interruption of blood supply to the myocardium. This study examines the medical records of 3205 STEMI patients admitted to the coronary care unit of the First Affiliated Hospital of Wenzhou Medical University from January 2014 to December 2021. In this research, a novel predictive framework for STEMI is proposed, incorporating evolutionary computational methods and machine learning techniques. A variant algorithm, AGCOSCA, is introduced by integrating crossover operation and observation bee strategy into the original Sine Cosine Algorithm (SCA). The effectiveness of AGCOSCA is initially validated using IEEE CEC 2017 benchmark functions, demonstrating its ability to mitigate the deficiency in local mining after SCA random perturbation. Building upon this foundation, the AGCOSCA approach has been paired with Support Vector Machine (SVM) to forge the predictive framework referred to as AGCOSCA-SVM. Specifically, AGCOSCA is employed to refine the selection of predictors from a substantial feature set before SVM is utilized to forecast the occurrence of STEMI. In our analysis, we observed that SVM excels at managing nonlinear data relationships, a strength that becomes particularly prominent in smaller datasets of STEMI patients. To assess the effectiveness of AGCOSCA-SVM, diagnostic experiments were conducted based on the STEMI sample data. Results indicate that AGCOSCA-SVM outperforms traditional machine learning methods, achieving superior Accuracy, Sensitivity, and Specificity values of 97.83 %, 93.75 %, and 96.67 %, respectively. The selected features, such as acute kidney injury (AKI) stage, fibrinogen, mean platelet volume (MPV), free triiodothyronine (FT3), diuretics, and Killip class during hospitalization, are identified as crucial for predicting STEMI. In conclusion, AGCOSCA-SVM emerges as a promising model framework for supporting the diagnostic process of STEMI, showcasing potential applications in clinical settings.

Abstract
INTRODUCTION Epidemic of cardiovascular disease (CVD) is widely projected in South Asian population and estimated to get double in two decades. Ischemic heart disease (IHD) is one of the spectrums of CVD and acute myocardial infarction (AMI) being the common manifestations of IHD. National Cardiovascular Data Registry (NCDR) is a registry data that measure their practices and improve quality of care. In this project we aim to see our performance trends in the care of IHD including AMI patients over two year's period. MATERIAL & METHODS A cross sectional study conducted at the Aga Khan University Hospital, Karachi, Pakistan. All patients aged 18 years and above admitted to adult Cardiology units with chest pain and acute coronary syndrome are eligible to be included in NCDR data set. Data on demographics and initial characteristics of patients were extracted from NCDR institutional dataset. The data was then compared between 2019 and 2020 on performance, quality, and efficiency metrics. RESULT In 2019 to 2020, 1542 patients with acute coronary syndrome and stable ischemic heart disease were admitted. Out of these, 1042 patients (67.8%) were males. According to our data, the 2020 mortality rate was about 5.25%. In 2019 and 2020, bleeding rates were 1.1% and 1.6%, respectively. Our data showed 100% PCI in 90 minutes in 2019 while 87% in 2020. According to the appropriateness criteria for PCI, 80% were appropriate, while 20% were possibly appropriate in both years. The median length of stay following a procedure was 2 days in 2019 and 1 day in 2020. CONCLUSION This study described the common and unique characteristics of patients with myocardial infarction representing population from South Asian region. Overall, the procedural performance measure and outcome metrics are up to the international benchmarks. Cultural, financial, and pandemic effects identified certain challenges.

Abstract
Background Important health care differences exist between the United States (US) and Canada, which may have been exacerbated during the pandemic. We compared clinical characteristics, treatment strategies, and clinical outcomes of patients with ST-segment elevation myocardial infarction (STEMI) and COVID-19 (STEMI-COVID) treated in the US and Canada. Methods The North American COVID-19 Myocardial Infarction registry is a prospective, investigator-initiated study enrolling patients with STEMI with confirmed or suspected COVID-19 in the US and Canada. The primary end point was in-hospital mortality. Additionally, we explored associations between vaccination and clinical outcomes. Results Of 853 patients with STEMI-COVID, 112 (13%) were enrolled in Canada, and compared with the US, patients in Canada were more likely to present with chest pain and less likely to have a history of heart failure, stroke/transient ischemic attack, pulmonary infiltrates or renal failure. In both countries, the primary percutaneous coronary intervention was the dominant reperfusion strategy, with no difference in door-to-balloon times; fibrinolysis was used less frequently in the US than in Canada. The adjusted in-hospital mortality was not different between the 2 countries (relative risk [RR], 1.0; 95% CI, 0.46-2.72; P = 1.0). However, the risk of in-hospital mortality was significantly higher in unvaccinated compared with vaccinated patients with STEMI-COVID (RR, 4.7; 95% CI, 1.7-11.53; P = .015). Conclusions Notable differences in morbidities and reperfusion strategies were evident between patients with STEMI-COVID in the US compared with Canada. No differences were noted for in-hospital mortality. Vaccination, regardless of region, appeared to associate with a lower risk of in-hospital mortality strongly.

Abstract
Background Disparities in acute coronary syndrome (ACS) outcomes exist between racial and ethnic groups. We aimed to evaluate disparities in resource utilization and inpatient outcomes across multiple ethnic and racial groups using contemporary data. Methods We identified hospital discharges for ACS in the United States using the National Inpatient Sample from 2015 to 2018. The International Classification of Diseases, Tenth Revision, Clinical Modification codes were used to identify variables of interest. The primary outcomes were in-hospital complications, length of stay, and total hospital charge. Statistical analysis was performed using STATA version 17. Results Our analysis included 1,911,869 ACS discharges. Our sample was made up of 78.6% White, 12.1% Black, and 9.3% Hispanic patients. Hispanic and Black patients presenting with ACS were younger and had more cardiometabolic comorbidities than their White counterparts, especially hypertension, diabetes mellitus, and obesity. Despite social determinants of health being more likely to be unfavorable for Hispanics than their White counterparts, they were more likely to incur higher total hospital charges than their White counterparts. Black patients were the least likely to undergo revascularization procedures. Despite these differences, White patients had higher in-hospital mortality rates than Black and Hispanic patients. Conclusions In this nationally representative study, despite having higher cardiometabolic comorbidity burden, lower socioeconomic status, and percutaneous intervention, Black and Hispanic patients experienced lower mortality rates than their White counterparts. Hispanic patients incurred the highest amount of total hospital charges for an ACS admission.

Abstract
AIMS Little is known about ethnic disparities in care and clinical outcomes of patients admitted with non-ST-segment elevation myocardial infarction (NSTEMI) in national cohorts from universal healthcare systems derived from Europe. METHODS AND RESULTS We identified 280 588 admissions with NSTEMI in the UK Myocardial Infarction National Audit Project (MINAP), 2010-2017, including White patients (n = 258 364) and Black, Asian, and Minority Ethnic (BAME) patients (n = 22 194). BAME patients were younger (66 years vs. 73 years, P < 0.001) and more frequently had hypertension (66% vs. 54%, P < 0.001), hypercholesterolaemia (49% vs. 34%, P < 0.001), and diabetes (48% vs. 24%, P < 0.001). BAME patients more frequently received invasive coronary angiography (80% vs. 68%, P < 0.001), percutaneous coronary intervention (PCI) (52% vs. 43%, P < 0.001), and coronary artery bypass graft surgery (9% vs. 7%, P < 0.001). Following propensity score matching, BAME compared with White patients had similar in-hospital all-cause mortality [odds ratio (OR) 0.91, confidence interval (CI) 0.76-1.06; P = 0.23], major bleeding (OR 0.99, CI 0.75-1.25; P = 0.95), re-infarction (OR 1.15, CI 0.84-1.46; P = 0.34), and major adverse cardiovascular events (MACE) (OR 0.94, CI 0.80-1.07; P = 0.35). CONCLUSION BAME patients with NSTEMI had higher cardiometabolic risk profiles and were more likely to undergo invasive angiography and revascularization, with similar clinical outcomes as those of their White counterparts. Among the quality indicators assessed, there is no evidence of care disparities among BAME patients presenting with NSTEMI.

Variation in Seeking Care for Cardiovascular Disease and Ambulance Utilization among Migrants in Australia: Time, Ethnicity, and Delay (TED) Study III. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19031516.

Abstract
Insight into differences in seeking medical care for chest pain among migrant populations is limited. This study aimed to determine ethnic differences in seeking care behaviors and using ambulances among migrants compared to an Australian-born group. A total of 607 patients presenting with chest pain to a tertiary hospital between 1 July 2012 and 30 June 2014 were randomly selected. Data from the emergency department dataset and medical record reviews were collected and linked for analysis. The migrant group was stratified into nine ethnic groups for analysis based on the Australian Standard Classification of Cultural and Ethnic Groups. The overall median prehospital delay time was 3.7 (1.5, 10.7) h, which ranged from 2.5 (1.0, 10.7) (Southern and Eastern European group) to 6.0 (2.3, 20.6) (Sub-Saharan African group). The median decision time was 2.0 (0.8, 7.9) h, which ranged from 1.5 (Australian-born group) to 4.5 h (Sub-Saharan African group). Five ethnic groups had significantly longer decision times compared to the Australian-born group. Decision time accounted for 58.4% of pre-hospital delay time. Migrant patients were 60% less likely to seek care for chest pain within one hour (odds ratio 0.40, (0.23–0.68), p = 0.001). There was no significant difference in ambulance utilization between migrant and Australian-born groups. In conclusion, ethnic differences in seeking care for chest pain do exist, and ethnicity plays a vital role in a longer delay in seeking care. To reduce the delays and improve patient outcomes, appropriate health campaigns focusing on ethnic differences among migrant populations and normalizing cultural competency into practice are recommended.

Abstract
AIM This clinical practice guideline for the evaluation and diagnosis of chest pain provides recommendations and algorithms for clinicians to assess and diagnose chest pain in adult patients. METHODS A comprehensive literature search was conducted from November 11, 2017, to May 1, 2020, encompassing randomized and nonrandomized trials, observational studies, registries, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Collaboration, Agency for Healthcare Research and Quality reports, and other relevant databases. Additional relevant studies, published through April 2021, were also considered. Structure: Chest pain is a frequent cause for emergency department visits in the United States. The "2021 AHA/ACC/ASE/CHEST/SAEM/SCCT/SCMR Guideline for the Evaluation and Diagnosis of Chest Pain" provides recommendations based on contemporary evidence on the assessment and evaluation of chest pain. This guideline presents an evidence-based approach to risk stratification and the diagnostic workup for the evaluation of chest pain. Cost-value considerations in diagnostic testing have been incorporated, and shared decision-making with patients is recommended.

Abstract
OBJECTIVES To identify clinical variables that are associated with the diagnosis acute coronary syndrome (ACS) in women and men with chest discomfort who contact out-of-hours primary care (OHS-PC) by telephone, and to explore whether there are indications whether these variables differ among women and men. DESIGN Cross-sectional study in which we compared patient and call characteristics of triage call recordings between women with and without ACS, and men with and without ACS. SETTING Nine OHS-PC in the Netherlands. PARTICIPANTS 993 women and 802 men who called OHS-PC for acute chest discomfort (pain, pressure, tightness or discomfort) between 2014 and 2016. PRIMARY OUTCOME MEASURE Diagnosis of ACS retrieved from the patient's medical record in general practice, including hospital specialists' discharge letters. RESULTS Among 1795 patients (mean age 58.8 (SD 19.5) years, 55.3% women), 15.0% of men and 8.6% of women had an ACS. In both sexes, retrosternal chest pain was associated with ACS (women with ACS vs without 62.3% vs 40.3%, p=0.002; men with ACS vs without 52.5% vs 39.7%, p=0.032; gender interaction, p=0.323), as was pressing/heavy/tightening pain (women 78.6% vs 61.5%, p=0.011; men 82.1% vs 57.4%, p=<0.001; gender interaction, p=0.368) and radiation to the arm (women 75.6% vs 45.9%, p<0.001; men 56.0% vs 34.8%, p<0.001; gender interaction, p=0.339). Results indicate that only in women were severe pain (65.4% vs 38.1%, p=0.006; gender interaction p=0.007) and radiation to jaw (50.0% vs 22.9%, p=0.007; gender interaction p=0.015) associated with ACS.Ambulances were dispatched equally in women (72.9%) and men with ACS (70.0%). CONCLUSION Our results indicate there were more similarities than differences in symptoms associated with the diagnosis ACS for women and men. Important exceptions were pain severity and radiation of pain in women. Whether these differences have an impact on predicting ACS needs to be further investigated with multivariable analyses. TRIAL REGISTRATION NUMBER NTR7331.

Abstract
Ethnic differences in the pathobiology of acute coronary syndromes (ACS) have not been systematically studied. We compared the underlying mechanisms of ACS between Asians and Whites. ACS patients with the culprit lesion imaged by optical coherence tomography were included. Patients were stratified into ST-elevation myocardial infarction (STEMI) and non-ST-elevation-ACS (NSTE-ACS), and baseline characteristics, underlying mechanisms of ACS, and culprit plaque characteristics were compared between Asians and Whites. Of 1,225 patients, 1,019 were Asian (567 STEMI and 452 NSTE-ACS) and 206 were White (71 STEMI and 135 NSTE-ACS). Asians had more diabetes and hypertension among STEMI patients; among NSTE-ACS patients, Asians had higher prevalence of diabetes and renal insufficiency, and lower prevalence of hyperlipidemia. There were no differences in the incidence of plaque rupture, plaque erosion and calcified plaque between Asians and Whites with STEMI (61.2%, 28.6%, 10.2% vs 46.5%, 38.0%, 15.5%, respectively, p = 0.055). Among NSTE-ACS patients, there was a significant difference between Asians and Whites (40.5%, 47.6%, 11.9% vs 27.4%, 48.9%, 23.7%, respectively, p = 0.001). After adjustment for clinical confounders, the risk of plaque rupture (p = 0.713), plaque erosion (p = 0.636), and calcified plaque (p = 0.986) was similar between the groups with STEMI. In NSTE-ACS patients, the only difference was an increased risk of calcified plaque in Whites (odds ratio: 2.125, 95% confidence interval: 1.213 to 3.723, p = 0.008). In conclusion, after adjustment for clinical confounders, Asian and White patients presenting with STEMI and NSTE-ACS showed similar underlying mechanisms of ACS, except for a higher risk of calcified plaque in Whites with NSTE-ACS.

Abstract
BACKGROUND We aimed to externally validate an emergency department triage algorithm including five hierarchical clinical variables developed to identify chest pain patients at low risk of having an acute coronary syndrome justifying delayed rather than immediate evaluation. METHODS In a single-centre cohort enrolling 29,269 consecutive patients presenting with chest pain, the performance of the algorithm was compared against the emergency department discharge diagnosis. In an international multicentre study enrolling 4069 patients, central adjudication by two independent cardiologists using all data derived from cardiac work-up including follow-up served as the reference. Triage towards 'low-risk' required absence of all five clinical 'high-risk' variables: history of coronary artery disease, diabetes, pressure-like chest pain, retrosternal chest pain and age above 40 years. Safety (sensitivity and negative predictive value (NPV)) and efficacy (percentage of patients classified as low risk) was tested in this initial proposal (Model A) and in two additional models: omitting age criteria (Model B) and allowing up to one (any) of the five high-risk variables (Model C). RESULTS The prevalence of acute coronary syndrome was 9.4% in the single-centre and 28.4% in the multicentre study. The triage algorithm had very high sensitivity/NPV in both cohorts (99.4%/99.1% and 99.9%/99.1%, respectively), but very low efficacy (6.2% and 2.7%, respectively). Model B resulted in sensitivity/NPV of 97.5%/98.3% and 96.1%/89.4%, while efficacy increased to 14.2% and 10.4%, respectively. Model C resulted in sensitivity/NPV of 96.7%/98.6% and 95.2%/91.3%, with a further increase in efficacy to 23.1% and 15.5%, respectively. CONCLUSION A triage algorithm for the identification of low-risk chest pain patients exclusively based on simple clinical variables provided reasonable performance characteristics possibly justifying delayed rather than immediate evaluation in the emergency department.

Comparison of Outcomes in Patients With Acute Coronary Syndrome Presenting With Typical Versus Atypical Symptoms. Am J Cardiol 2019; 124:1851-1856. [PMID: 31653357 DOI: 10.1016/j.amjcard.2019.09.007] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2019] [Revised: 09/16/2019] [Accepted: 09/16/2019] [Indexed: 02/01/2023]
Abstract
Although typical chest pain is an important clinical feature required for diagnosis of acute coronary syndrome (ACS), many patients present with atypical complaints. The full extent and implication of this presentation is largely unknown. The study aim was to evaluate possible relations and temporal trends between presenting symptoms and outcomes in patients with ACS. Data was obtained from the Acute Coronary Syndrome Israeli Survey on patients presenting with typical chest pain versus atypical complaints, including dyspnea, nonspecific chest pain, palpitations or other. Temporal trends analysis examined the early (2000 to 2006) versus the late (2008 to 2016) period. During 2000 to 2016, 14,722 patients with ACS were enrolled; 11,508 (79%) presented with typical chest pain and 3,214 (21%) with atypical complaints. Patients with atypical complaints were older, majority female, and had more co-morbidities (p <0.001 for each). The 30-day major adverse cardiac events, 30-day mortality, and 1-year mortality rate were significantly higher in patients presenting with atypical complaints, (18% vs 13.5%, 7.7% vs 3.6%, and 15.6% vs 7.5%, respectively, p <0.001 for each). Although 1-year mortality decreased significantly over the years in patients with typical chest pain, there were no significant changes in patients who presented with atypical complaints. These results were consistent in STEMI and non-STE-ACS patients. In conclusion, ACS patients who present with atypical complaints have a less favorable outcome compared with patients who present with typical chest pain, and failed to show an improvement in mortality over the past 2 decades. Identification and utilization of guideline-recommended therapies in these high-risk patients may improve their future outcome.

Abstract
South Asians (SAs), originating from the Indian subcontinent (India, Pakistan, Sri Lanka, Bangladesh, Nepal, and Bhutan), represent one quarter of the global population and are the largest visible minority in Canada. SAs experience the highest rates of coronary artery disease in Canada. Although conventional cardiovascular risk factors remain predictive in SA, the excess risk is not fully explained by these risk factors alone. Abdominal obesity, metabolic syndrome, and insulin resistance likely contribute a greater risk in SAs than in other populations. The South Asian Heart Alliance has been recently formed to investigate and recommend the best strategies for the prevention of cardiometabolic disease in SAs in Canada. This topic review represents a comprehensive overview of the magnitude of cardiovascular disease in SAs in Canada, with a review of conventional and novel risk markers in the SA population. Both primary and secondary prevention strategies are suggested and when possible, adapted specifically for the SA population. The need for SAs and their healthcare professionals to be more aware of the problem and potential solutions, along with the need for population-specific research, is highlighted.
