Background: Reduced Left Ventricular Ejection Fraction (LVEF) is considered to worsen prognosis after an acute myocardial infarction (AMI), including Non-ST-elevation myocardial infarction (NSTEMI). This study aims to find a correlation between LVEF with mortality risk after hospital discharge following myocardial infarction using GRACE score among NSTEMI patients. Methods: Data was collected from the iSTEMI Registry database in Prof. Dr. R. D. Kandou General Hospital from October 3rd 2018, to July 28th 2019. About 122 NSTEMI patients were collected to measure their LVEF by transthoracic echocardiography and routine clinical workup for GRACE score calculation at admission. A descriptive analysis, normality test, and bivariate correlation were applied. A p-value less than 0.05 was considered statistically significant using SPSS version 23 for Windows. Results: The mean age of the patients was 62.07±11.11 years old and most of the study subjects were male (73%). The mean GRACE score was 118.92±33.52, whereas the mean ejection fraction was 48.76±16.32%. LVEF was negatively significant correlated with the GRACE score (p=0.017; r=-0.230). Conclusion: Lower LVEF is correlated with increased six-month mortality risk after hospital discharge using GRACE score following myocardial infarction in a patient with Non-ST-elevation myocardial Infarction.
