Beta-blockers are associated with reverse remodeling in patients with dilated cardiomyopathy and mid-range ejection fraction.

ABSTRACT:

Background

Beta-blockers have been shown to induce left ventricular reverse remodeling (LVRR) in heart failure with reduced ejection fraction. This study aimed to determine whether beta-blockers could induce LVRR in patients with heart failure with mid-range ejection fraction (HFmrEF).

Methods

We analyzed the national database from clinical personal records of dilated cardiomyopathy (DCM) maintained by Japanese Ministry of Health, Labour and Welfare, between 2003 and 2014. Patients with left ventricular ejection fraction (LVEF) of ≥40% and < 50% were included. Patients who did not have echocardiography at 2 years of follow-up were excluded. Eligible patients were divided into two groups according to the use of beta-blockers. Patient characteristics of two groups were adjuste
