Left-atrioventricular interaction and left-atrial deformation in patients with type 2 diabetes mellitus with or without chronic aortic regurgitation: a 3.0-T cardiac magnetic resonance feature-tracking study.

ABSTRACT:

Background

The prevalence of type 2 diabetes mellitus (T2DM) and chronic aortic regurgitation (AR) increases with age and may also increase cardiac morbidity and mortality; however, their comprehensive effects based on cardiac strain remain unexplored. This study aimed to use cardiac magnetic resonance (CMR) feature tracking to investigate the additive effects of T2DM and AR on the left heart and left-atrioventricular interaction in patients with T2DM and AR.

Methods

A total of 286 patients with T2DM (203 without AR and 83 with AR) and 105 controls were retrospectively included from January 2015 to October 2022. The patients with T2DM and AR were divided according to echocardiographic findings into three AR groups: mild (n=39), moderate (n=25), and severe (n=19). The left-at
