Left ventricular outflow tract velocity time integral in hospitalized heart failure with preserved ejection fraction.

ABSTRACT:

Aims

The prognostic implication of left ventricular outflow tract velocity time integral (LVOT-VTI) on admission in hospitalized heart failure with preserved ejection fraction (HFpEF) patients has not been determined. We sought to investigate whether LVOT-VTI on admission is associated with worse clinical outcomes in hospitalized patients with HFpEF.

Methods and results

We studied consecutive 214 hospitalized HFpEF patients who had accessible LVOT-VTI data on admission, from a prospective HFpEF-specific multicentre registry. The primary outcome of interest was the composite of all-cause death and readmission due to heart failure. During a median follow-up period of 688 (interquartile range 162-810) days, the primary outcome occurred in 83 patients (39%). The optimal cut-off
