Impact of left ventricular dilatation on biventricular function and deformation in diabetes mellitus with reduced ejection fraction: a CMR feature tracking study.

ABSTRACT:

Background

Left ventricular (LV) dilatation has been found to be associated with poor prognosis in patients with reduced left ventricular ejection fraction (LVEF). However, the relationship between LV dilatation and biventricular myocardial dysfunction in patients with diabetes mellitus (DM) and reduced LVEF unclear.

Methods

From September 2017 to March 2025, 265 clinically diagnosed patients with DM who underwent cardiac magnetic resonance (CMR) scanning in our hospital were included. According to LVEF and LV dilatation status, these patients were divided into three groups: 122 DM with preserved LVEF (DMpEF) group, 51 DM with reduced LVEF and no LV dilatation (DMrEF-NLVD) group, and 92 DM with dilated cardiomyopathy (DMrEF-DCM) group. Biventricular strain parameters, includ
