Abstract Background During telephone triage, it is difficult to assign adequate urgency to patients with chest discomfort. Considering the time of calling could be helpful. Objective To assess the risk of acute coronary syndrome (ACS) in certain time periods and whether sex influences this risk. Methods Cross-sectional study of 1655 recordings of telephone conversations of patients who called the out-of-hours services primary care (OHS-PC) for chest discomfort. Call time, patient characteristics, symptoms, medical history and urgency allocation of the triage conversations were collected. The final diagnosis of each call was retrieved at the patient’s general practice. Absolute numbers of patients with and without ACS were plotted and risks per hour were calculated. The risk ratio of ACS at night (0 to 9 am) was calculated by comparing to the risk at other hours and was adjusted for gender and age. Results The mean age of callers was 58.9 (standard deviation ±19.5) years, 55.5% were women and, in total, 199 (12.0%) had an ACS. The crude risk ratio for an ACS at night was 1.80 (confidence interval 1.39–2.34, P < 0.001): 2.33 (1.68–3.22, P < 0.001) for men and 1.29 (0.83–1.99, P = 0.256) for women. The adjusted risk ratio for ACS of all people at night was 1.82 (1.07–3.10, P = 0.039). Conclusions Patients calling the OHS-PC for chest discomfort between 0 and 9 am have almost twice a higher risk of ACS than those calling other hours, a phenomenon more evident in men than in women. At night, dispatching ambulances more ‘straightaway’ could be considered for these patients with chest discomfort. Trial number NTR7331.

Introduction: Ischaemic Heart Diseases (IHD) are increasing at an alarming rate globally. Pharmacotherapy, the mainstay of management of IHD, has Dual Antiplatelet Therapy (DAPT) at its crux. DAPT, comprising of clopidogrel and aspirin, is used often for 12 months in medically managed Acute Coronary Syndrome (ACS). Clopidogrel being a prodrug, needs to be activated after ingestion, mainly by Cytochrome family of enzymes, for the desired pharmacological effects. Abnormal enzymes that convert clopidogrel to its active form can reduce the effectiveness of the drug. Therefore, Single Nucleotide Polymorphisms (SNPs) of the enzymes involved, would predispose the patient to therapy failure and recurrence of the illness. This study aims at identifying the presence of a genetic variant associated with clopidogrel responsiveness in patients with ACS. Aim: To estimate the frequency of CYP2C19*2 allele in patients with ACS presenting to Government Medical College, Thrissur, Kerala, India. Materials and Methods: Present study was a cross-sectional study done among 60 patients who presented to Government Medical College, Thrissur with ACS, between June 2018 to June 2019. Having obtained informed consent from the participants blood samples were collected in Ethylene diamine tetra-acetic Acid (EDTA) tubes. Samples were used to look for presence of CYP2C19*2 allele by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). Results: Out of 60 patients 38 were males and 22 were females. Most common age group was 61-65 years. The frequency of CYP2C19*2 allele was 41% in the study population and the variant genotype (AA/AG) was present in 62%. Conclusion: The variant genotype was found to be present in a high frequency in the study population implying the high risk for therapy failure in the study population. This asserts the need to probe the matter further, as the gene is also implicated in the metabolism of several other drugs. The introduction of pharmacogenomic testing prior to initiation of therapy may be therefore recommended for better treatment outcome. However, to validate the same, further studies with larger sample size may be necessary.

Background and purpose: Linked with high mortality rate, depression is common among acute coronary syndrome (ACS) patients. The current study sought to identify the factors associated with depression among ACS patients in Malaysia. Materials and Methods: A cross-sectional study was conducted on 400 ACS patients in two Malaysian hospitals: Hospital Universiti Sains Malaysia (USM), Kelantan and Hospital Sultanah Nur Zahirah (HSNZ), Terengganu. ACS patients were included if they were above 18 years of age, able to read and/or write in Bahasa Melayu language and had informed consent. Patients were excluded if they were intubated, had an altered mental status, mental retardation and had psychological problems prior to ACS. Depression in this study was defined as having dysphoria, hopelessness, devaluation of life, self-deprecation, lack of interest or involvement, anhedonia, and inertia among ACS patients. A questionnaire was distributed to all 400 ACS patients. Simple and multiple logistic regressions were used for data analysis. Results: The mean (standard deviation) age of ACS patients was 60.4 (11.3) years at Hospital USM and 61.2 (10.4) years at HSNZ. Nearly all of the depressive-ACS patients were Malay (79.4%), 85.9% were male, and 79.7% were married. Approximately 87.7% of depressive-ACS patients had ischemic heart disease, 87.1% had stroke, 83.4% had hyperlipidaemia, 81.8% had diabetes mellitus, and 80.7% had hypertension. The factors associated with depression were female gender (adjusted odd ratio (OR): 2.48, 95% confidence interval (CI): 1.50, 4.10, p<0.001) and ischemic heart disease (adjusted OR: 2.44, 95% CI: 1.41, 4.25, p=0.002). Conclusion: The results showed that female gender and ischemic heart disease were the most significant associated factors of depression among ACS patients.

ObjectiveTo evaluate the association between socioeconomic status (SES) and referral to cardiac rehabilitation (CR) after incident acute coronary syndrome (ACS) by dividing the referral process into three phases: (1) informed about CR, (2) willingness to participate in CR, (3) and assigned CR setting.DesignCross-sectional study.SettingDepartment of Cardiology at a Danish University Hospital from 1 January 2011 to 31 December 2014.ParticipantsA total of 1229 patients assessed for CR during hospitalisation with ACS were prospectively registered in the Rehab-North Register from 2011 to 2014. SES was assessed using data from national registers, concerning: personal income, occupational status, educational level and civil status. Patients were excluded if one of the following criteria was fulfilled: (1) missing data on SES, or (2) acceptable reason for not informing patients about CR (treatment with coronary artery bypass grafting, transfer to another hospital, still under treatment or death).Main outcome measuresOutcomes were defined by dividing the referral process into three phases: (1) informed about CR, (2) willingness to participate, and (3) assigned CR setting (in-hospital/community centre) after ACS.ResultsA total of 854 (69.5 %) patients were referred to CR. After adjustment for age, gender, ACS diagnosis (ST-elevated myocardial infarction, non-ST-elevated myocardial infarction, unstable angina pectoris) and comorbidity, high income had the strongest association of referral to CR in all three phases (informed about CR: OR 2.17, 95% CI 1.01 to 4.64; willingness to participate in CR: OR 1.55, 95% CI 1.02 to 2.35; assigned in-hospital CR: OR 1.47, 95% CI 0.91 to 2.36). Educational level showed similar tendencies, however not statistically significant. The results did not vary according to gender.ConclusionThis is the first study to investigate the referral process to CR using a three-phase structure. It suggests income and education to influence all phases in the referral process to CR after ACS.

Coronary Syndrome

Introduction: Coronary Artery Disease (CAD) is the leading cause of death worldwide. India has the highest burden of Acute Coronary Syndrome (ACS). Atherogenesis is a multifactorial process, abnormalities in lipoprotein metabolism especially elevated Low Density Lipoprotein Cholesterol (LDLc) remains one of most attributing key factor. Atherogenic Index of Plasma (AIP), can be calculated easily from the formula AIP=Log 10 Triglyceride (TG)/High Density Lipoprotein Cholesterol (HDLc). The AIP is inversely proportional to the diameter of LDLc particles, which indirectly reflects Small Dense LDLc levels. AIP has been proposed as a marker for Cardiovascular (CV) risk. Aim: The study aimed to assess the correlation between AIP and the Angiographic Profile by Gensini Score (GS) in ACS patients and also to evaluate the relationship between AIP and in-hospital mortality of ACS patients. Materials and Methods: This study was a hospital based cross- sectional study. This study was done from November 2019 to October 2020 in the Department of Cardiology, Sriram Chandra Bhanja Medical College, Odisha, India. A total of 240 patients of ACS were included in the study. AIP was calculated from the lipid profile of all the ACS patients. Coronary Angiography was done in all of these patients. Correlation of the AIP was done with the severity of CAD according to Gensini scoring system. Chi-square test was used to compare continuous variables p<0.05 was considered significant. Spearman’s rho correlation was also used to compare AIP with GS. Statistical analysis was performed using Statistical Package for the Social Sciences, (SPSS) 26 (IBM). Results: Majority of the cases were males 194 (80.8%) and females were 46 (19.2%). The Spearmans rho coefficient between AIP and GS was 0.663. It was statistically significant (p<0.001). AIP had positive correlation (value) with severity of CAD by GS. In-hospital mortality was 5%. It was more in high risk AIP group with a p-value of 0.006 which was statistically significant. Conclusion: AIP shows positive correlation with the severity of CAD in terms of GS. High AIP is also associated with increased in-hospital mortality. AIP can be used in the treatment of ACS patients and is a suitable alternative to various costly biomarkers of CAD. Therefore, AIP can be advocated for routine measurement in clinical practice.
