Prognostic role of the left ventricular global function index in predicting major adverse cardiovascular events in acute coronary syndrome patients

Abstract

Aim: This study aimed to evaluate the prognostic role of the left ventricular (LV) global function index (LVGFI) in predicting major adverse cardiovascular events in patients with acute coronary syndrome after long-term follow-up. Methods: This retrospective study included 718 patients with ST-elevated myocardial infarction (STEMI) and 781 patients with non-ST-elevated myocardial infarction (NSTEMI). The LVGFI was calculated on echocardiography with the following formula: (LV stroke volume/[LV cavity volume + LV myocardial volume]) × 100. Results: Mean LVGFI was higher in the NSTEMI group than in the STEMI group. Decreased LVGFI levels were independent predictors of major adverse cardiovascular events in both the STEMI and the NSTEMI group. Conclusion: Echocardiographic LVGFI may be a useful prognostic screening tool for acute coronary syndrome cohorts.
