Factors Associated With the Recovery of Left Ventricular Ejection Fraction in Patients With Anthracycline-Induced Left Ventricular Dysfunction

Abstract

Background: Neurohormonal blocking drugs, like beta-blockers, angiotensin-converting enzyme inhibitors (ACEIs), and angiotensin receptor blockers (ARBs), are recommended for treating anthracycline-induced left ventricular dysfunction (AILVD). However, there is limited evidence supporting their benefit. Therefore, this study evaluated associations of neurohormonal blockers and other clinical factors with recovery of left ventricular ejection fraction (LVEF) in patients with AILVD. Methods: This retrospective chart review assessed patients treated with at least one dose of anthracycline, then had ≥10% LVEF reduction or post-anthracycline LVEF value <50%, and then had a follow-up LVEF measurement ≥90 days later. The primary endpoint was LVEF recovery (highest follow-up LVEF−lowest LVEF post-anthracycline). Variables from univariable tests with P
