Clinical utility of the four-dimensional automatic left atrial quantification technique in evaluating left atrial volume and function in patients with heart failure with preserved ejection fraction
Abstract
Background: Left atrial (LA) dysfunction is common in patients with heart failure with preserved ejection fraction (HFpEF). However, there are few reports on LA circumferential strain in this patient population. In this study, we investigated the clinical utility of four-dimensional automatic left atrial quantification (4D LAQ) technology in evaluating LA volume, function, and strain in patients with HFpEF. Methods: FPEF) scale, patients were assigned to the HFpEF or non-HFpEF groups. Age- and sex-matched volunteers served as the control group. Results: Compared with the healthy controls, patients with HFpEF had a significantly higher LA minimum volume (LAVmin), LA maximum volume (LAVmax), LA presystolic volume (LAVpreA), and maximum volume index (LAVImax) (P
