Right ventricular (RV)-pulmonary circulation (PC) uncoupling is associated with poor outcome in patients with Heart Failure with Preserved Ejection Fraction (HFpEF). Tricuspid annular plane systolic excursion (TAPSE) and pulmonary artery systolic pressure (PASP) ratio is simple echo-derived indicator of RV-PC uncoupling. This study aimed to investigate the prognostic impact of TAPSE/PASP ratio among patients with HFpEF hospitalized for acute heart failure (AHF).
