Predictors and Prognosis of Right Ventricular Function in Pulmonary Hypertension Due to Heart Failure with Reduced Ejection Fraction

Abstract

The RV-PA coupling ratio Ees/Ea predicts overall survival in PH due to HFREF and is mainly affected by pulsatile load, RV remodelling, and left ventricular dysfunction. Prognostically favourable coupling (RV-Ees/Ea ≥ 0.68) in PH was associated with preserved RV size/function and mid-term survival, comparable with HFREF without PH.
