Prognostic Impact of Echocardiographic Congestion Grade in HFpEF With and Without Atrial Fibrillation.

ABSTRACT:

Background

Atrial fibrillation (AF) is common in heart failure with preserved ejection fraction (HFpEF).

Objectives

This study aimed to investigate the prognostic value of echocardiographic markers of congestion that can be applied to both AF and patients without AF with HFpEF.

Methods

We conducted a multicenter study of 505 patients with HFpEF admitted to hospitals for acute decompensated heart failure. The ratio of early diastolic transmitral flow velocity to mitral annulus velocity (E/e'), the tricuspid regurgitation peak velocity, and the collapsibility of the inferior vena cava were obtained at discharge. Congestion was determined by echocardiography if any one of E/e' ≥14 (E/e' ≥11 for AF), tricuspid regurgitation peak velocity ≥2.8 m/s, or inferior vena cava co
