LEFT ATRIAL END DIASTOLIC VOLUME INDEX AS A PREDICTOR FOR MAJOR ADVERSE CARDIOVASCULAR EVENT FOR 30 DAYS AFTER ADMISSION, IN PATIENTS WITH STEMI IN HAJI ADAM MALIK GENERAL HOSPITAL MEDAN

Abstract

Background: Ischemic heart disease is the leading cause of death in the world (12.8%) while in Indonesia it ranks third. The prevalence of coronary heart disease in Indonesia in 2013 is estimated to be around 883,447 (0.5%) Left Atrial Residual Volume Index, or Left Atrial End-Diastolic Volume Index (LAEDVI) is the smallest LA volume, measured at the end of the ventricular diastole. LAEDVI measurements have shown a closer correlation with LV filling pressure than LAESVI

Purpose: To determine Value of Left Atrial End Diastolic Index as a Predictor of Major Adverse Cardiovascular Events (MACE) for 30 days after admission, in patients with STEMI through echocardiography examination

Method: This study involved STEMI patients who were treated at Haji Adam Malik General Hospital Medan from March 2020 to November 2020. Each patient will undergo echocardiography and the LAEDVI values and others parameters. Observation of the occurrence of MACE on STEMI was carried out for 30 days after treatment. Multivariate analysis of independent variables with categorical dependent variables was tested by logistic regression to determine the predictive factors LAEDVI as predictors of MACE on STEMI.

Result: From 52 STEMI patients, there were 16 cases of MACE consisting of 11 patients with acute heart failure and 5 patients with arrhythmia. The LAEDVI value became a predictor factor that was statistically significant with OR 3.119 (CI95% 1.278-7.615) and p value = 0.012, the constant is -20.116. With cut-off point score LAEDVI against the incidence of Major Cardiovascular Events is 17.15 mL/m2 . Conclusion: LAEDVI is a potential tool to predict Major Adverse Cardiovascular Events (MACE) in STEMI patients.
