Heart Failure Therapies following Acute Coronary Syndromes with Reduced Ejection Fraction: Data from the ACSIS Survey

Abstract

Background: Guideline-directed medical therapies for heart failure (HF) may benefit patients with reduced left ventricular ejection fraction (LVEF) following acute coronary syndromes (ACS). Few real-world data are available regarding the early implementation of HF therapies in patients with ACS and reduced LVEF. Methods: Data collected from the 2021 nationwide, prospective ACS Israeli Survey (ACSIS). Drug classes included: (a) angiotensin-converting enzyme inhibitors (ACEI), angiotensin receptor blockers (ARB) or angiotensin receptor-neprilysin inhibitors (ARNI); (b) beta-blockers; (c) mineralocorticoid receptor antagonist (MRA) and (d) sodium-glucose cotransporter-2 inhibitors (SGLT2I). The utilization of HF therapies at discharge or 90 days following ACS was analyzed in relation to LVEF [reduced ≤40% (n = 406) or mildly-reduced 41–49% (n = 255)] and short-term adverse outcomes. Results: History of HF, anterior wall myocardial infarction and Killip class II-IV (32% vs. 14% p p = 0.084. No association was observed between the number of HF drug classes or the use of ARNI and/or SGLT2I with adverse clinical outcomes. Conclusions: In current clinical practice, the majority of patients with reduced and mildly-reduced LVEF are treated by ACEI/ARB and beta-blockers early following ACS, whereas MRA is underutilized and the adoption of SGLT2I and ARNI is low. A greater number of therapeutic classes was not associated with reduced short-term rehospitalizations or mortality.
