Summary Introduction: acute coronary syndromes (ACS) represent a widely prevalent health issue with high mortality in Brazil and worldwide. The severity of ACS is not known in patients in the city of São Bernardo do Campo a municipality contiguous and adjacent to the city of São Paulo. Objectives: to study the profile of coronary disease in patients hospitalized with ACS who underwent coronary angiography in the emergency room between 2012 and 2013. Methods: this is an observational study that included consecutive patients with ACS admitted to the emergency room of a hospital. Data collection was performed using medical records with the following variables: sex, age, risk factors for cardiovascular disease, coronary angiography. Results: the sample in this period included 131 patients, of which 64.8% were men. The most prevalent diagnosis was ST-elevation myocardial infarction (STEMI) (57.2%) followed by non-ST-elevation myocardial infarction (NSTEMI) (22.1%) and unstable angina (UA) (20.6%). There were no significant differences in the epidemiology and risk factors between the diagnoses, except that heart failure was more prevalent in patients with UA. Discussion: there were no differences between groups regarding the coronaries involved; however, STEMI patients showed similar numbers of multi- and singlevessel lesions, NSTEMI patients showed more multivessel lesions, and UA patients showed more multivessel lesions or lesion-free arteries. Although multivessel lesions were prevalent in all groups, STEMI patients showed a significantly higher number of single-vessel lesions compared with the other acute coronary syndromes. Conclusion: the study demonstrated a predominance of STEMI in the studied population, which differs from the usual results in ACS.

• Acute coronary syndromes (ACS) encompass a spectrum of presentations which include unstable angina, non-ST-elevation myocardial infarction (NSTEMI or NSTE-ACS), and ST-elevation myocardial infarction (STEMI or STE-ACS)• Anti-platelet and anti-thrombotic agents are administered as ancillary therapy to myocardial reperfusion in patients presenting with an acute coronary syndrome, to maintain the patency of the infarct-related coronary artery• More specific and potent inhibitors of platelet activation and of the coagulation cascade are emerging with the aim being to further improve clinical outcomes in patients presenting with an acute coronary syndrome, without increasing the risks of major bleeding.

Background. Each year, approximately 5000 New Zealanders are admitted to hospital with first-time acute coronary syndrome (ACS). The Multi-Ethnic New Zealand Study of Acute Coronary Syndromes (MENZACS) is a prospective longitudinal cohort study embedded within the All New Zealand Acute Coronary Syndrome Quality Improvement (ANZACS-QI) registry in six hospitals. The objective of MENZACS is to examine the relationship between clinical, genomic, and cardiometabolic markers in relation to presentation and outcomes post-ACS. Methods. Patients with first-time ACS are enrolled and study-specific research data is collected alongside the ANZACS-QI registry. The research blood samples are stored for future genetic/biomarker assays. Dietary information is collected with a food frequency questionnaire and information about physical activity, smoking, and stress is also collected via questionnaire. Detailed family history, ancestry, and ethnicity data are recorded on all participants. Results. During the period between 2015 and 2019, there were 2015 patients enrolled. The mean age was 61 years, with 60% of patients aged <65 years and 21% were female. Ethnicity and cardiovascular (CV) risk factor distribution was similar to ANZACS-QI: 13% Māori, 5% Pacific, 5% Indian, and 74% NZ European. In terms of CV risk factors, 56% were ex-/current smokers, 42% had hypertension, and 19% had diabetes. ACS subtype was ST elevation myocardial infarction (STEMI) in 41%, non-ST elevation myocardial infarction (NSTEM) in 54%, and unstable angina in 5%. Ninety-nine percent of MENZACS participants underwent coronary angiography and 90% had revascularization; there were high rates of prescription of secondary prevention medications upon discharge from hospital. Conclusion. MENZACS represents a cohort with optimal contemporary management and will be a significant epidemiological bioresource for the study of environmental and genetic factors contributing to ACS in New Zealand’s multi-ethnic environment. The study will utilise clinical, nutritional, lifestyle, genomic, and biomarker analyses to explore factors influencing the progression of coronary disease and develop risk prediction models for health outcomes.

Abstract Abstract 3171 Introduction: Changes in plasma volume, the intravascular portion of the extracellular fluid volume, can be estimated by measuring changes in the levels of hemoglobin and hematocrit in the blood. In addition to hemoglobin & hematocrit levels, we are also able to use standard dilution techniques with radiolabeled albumin to accurately measure plasma volume changes. It is not known if plasma volume changes influence outcomes in patients with acute coronary syndromes. The aim of this study was to evaluate the effects of plasma volume changes in patients presenting with the acute coronary syndromes. Methods: Consecutive patients presenting to a single tertiary care center from January 2001 to December 2010 with non ST elevation myocardial infarction (NSTEMI) or ST elevation myocardial infarction (STEMI) were enrolled. Admission hemoglobin (Hbpre) & hematocrit (Hctpre) and discharge hemoglobin (Hbpost) and hematocrit levels (Hctpost) were obtained. Plasma volume changes were measured and a validated formula (ΔPV = ((Hbpre/Hbpost) × (100-Hctpost/100-Hctpre)-1) × 100%) was used to calculate the changes in plasma volumes. A detailed chart review was performed to collect information about baseline variables such as age, gender, hypertension, diabetes, hyperlipidemia, smoking status, and congestive heart failure. The Framingham Risk score was also calculated for each individual. Survival analysis was carried out for plasma volume changes of -20% - 0%, 0 – 20%, and ≥20%. Mortality data was collected from the social security death index for the first 60 days post-discharge. Results: A total of 9770 patients with confirmed NSTEMI or STEMI (mean age 61.8 ± 4.8 years, 48.8% women) were included in the final analysis. Mean pre admission hemoglobin (Hbpre) was 10.2 ± 1.4 g/dl and post admission hemoglobin (Hbpost) was 10.4 ± 1.3 g/dl. Change in plasma volume, ΔPV, was categorized into one of four categories, with 131 (1.3%) ≤20%, 6126 (62.7%) -20% - 0%, 3393 (34.7%) 0 – 20%, and 120 (1.2%) ≥20%. There were 509 deaths within 60 days of discharge. Change in plasma volume was found to be an independent predictor of mortality (HR 5.71; 95% CI 4.75 – 6.86, p = 0.0001) in a Cox proportional hazard model. Most of the deaths occurred during the first thirty days as demonstrated by the Kaplan – Meier's survival curve (Figure 1). Receiver operating curve showed an area under the curve of 0.876 for changes in plasma volume. Conclusion: This study shows that hemoglobin and hematocrit, although simple tests, can provide important prognostic information strongly predictive of short term mortality in patients with acute coronary syndromes. Further studies are required to see if monitoring of plasma volume and correction with pharmacological agents such as diuretics may lead to better outcomes. Disclosures: No relevant conflicts of interest to declare.

Potential Use

Regardless of the newly diagnostic and therapeutic advances, coronary artery disease (CAD) and more explicitly, ST-elevation myocardial infarction (STEMI), remains one of the leading causes of morbidity and mortality worldwide. Thus, early and prompt diagnosis of cardiac dysfunction is pivotal in STEMI patients for a better prognosis and outcome. In recent years, microRNAs (miRNAs) gained attention as potential biomarkers in myocardial infarction (MI) and acute coronary syndromes (ACS), as they have key roles in heart development, various cardiac processes, and act as indicators of cardiac damage. In this review, we describe the current available knowledge about cardiac miRNAs and their functions, and focus mainly on their potential use as novel circulating diagnostic and prognostic biomarkers in STEMI.
