Multicenter Study Observational StudyRight ventricular dysfunction in left-sided heart failure with preserved versus reduced ejection fraction.
Right ventricular (RV) dysfunction is recognized as a major prognostic factor in left-sided heart failure (HF). However, the relative contribution of RV dysfunction in HF with preserved (HFpEF) vs. reduced ejection fraction (HFrEF) is unclear. ⋯ Right ventricular dysfunction is present in HFpEF and is even more pronounced in HFrEF for any given degree of pulmonary hypertension. It is independently predicted by left ventricular dysfunction but not by PASP. Right ventricular-arterial coupling is prognostically important in HF regardless of LVEF.
