The predictive value of changes in left atrial volume index for rehospitalization in heart failure with preserved ejection fraction.

ABSTRACT:

Aims

Left atrial volume index (LAVI) is an adequate analysis to predicate the left ventricle (LV) filling pressures, providing a powerful predictive marker of LV diastolic dysfunction. LAVI is a dynamic morphophysiological marker, and whether LAVI changes can predicate clinical outcomes in HF with preserved ejection fraction (HFpEF) is unknown.

Methods

HFpEF patients were retrospectively studied from the First Affiliated Hospital of Dalian Medical University. Patients were classified into deteriorated, stable and improved groups according to the change in LAVI. Rehospitalization was defined as the main endpoint, the composite outcome of rehospitalization or all-cause death was defined as the secondary endpoint.

Results

A total of 409 patients were included. In this co
