Right Atrial Phasic Function in Heart Failure With Preserved and Reduced Ejection Fraction.

ABSTRACT:

Objectives

This study researched right atrial (RA) deformation indexes and their association with all-cause mortality among subjects with or without heart failure (HF).

Background

Although left atrial dysfunction is well described in HF, patterns of RA dysfunction and their prognostic implications are unclear. Cardiac magnetic resonance (CMR) imaging can provide excellent visualization of the RA. We used CMR to characterize RA phasic function in HF and to assess its prognostic implications.

Methods

This study prospectively examined 608 adults without HF (n = 407), as well as adults with HF with a reduced ejection fraction (HFrEF) (n = 105) or with HF with a preserved ejection fraction (HFpEF) (n = 96). Phasic RA function was measured via volume measurements and featur
