Abstract

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 3^rd 2018, to July 28^th 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.
