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.

After a heart attack, poor heart performance is an important cause of major adverse cardiovascular events (MACEs). The left ventricular global function index (LVGFI) is a new index that evaluates cardiac performance. Early identification of patients with poor heart performance following a heart attack could prevent the occurrence of major adverse cardiovascular events and improve survival. This study aimed to explore whether the LVGFI is associated with the risk of MACEs in heart attack patients. We found that a decrease in LVGFI levels was independently associated with MACEs at 3-year follow-up in patients after a heart attack. Accordingly, we showed that an assessment of LVGFI using echocardiography offers a good distinction in identifying patients at risk for MACE after a heart attack. These findings indicate that the LVGFI may be helpful in identifying high-risk patients and optimizing treatment strategies in clinical practice.
