Multicenter StudyRV Contractile Function and its Coupling to Pulmonary Circulation in Heart Failure With Preserved Ejection Fraction: Stratification of Clinical Phenotypes and Outcomes.
This study sought to investigate how right ventricular (RV) contractile function and its coupling with pulmonary circulation (PC) stratify clinical phenotypes and outcome in heart failure preserved ejection fraction (HFpEF) patients. ⋯ A thorough assessment of RV-PC coupling and RV contractile function stratify HFpEF phenotypes at different level of risk. These observations shift the interest toward therapeutic strategies that may benefit the right heart as primary unmet need in the complex pathophysiology of the HFpEF syndrome.
