N2 - Background: Limited data exist to characterize novel measures of right ventricular (RV) function and the coupling to pulmonary circulation in patients with heart failure and preserved left ventricular ejection fraction (HFpEF). Objectives: This study sought to assess the clinical implications of RV function, the association with N-terminal pro–B-type natriuretic peptide, and the risk for adverse events among patients with HFpEF. Methods: This study analyzed measures of RV function by assessing absolute RV free wall longitudinal strain (RVFWLS) and its ratio to estimated pulmonary artery systolic pressure (PASP) (RVFWLS/PASP ratio) in 528 patients (mean age 74 ± 8 years, 56% female) with adequate echocardiographic images quality enrolled in the PARAGON-HF trial. Associations with baseline N-terminal pro–B-type natriuretic peptide and with total HF hospitalizations and cardiovascular death were assessed, after accounting for confounders. Results: Overall, 311 patients (58%) had evidence of RV dysfunction, defined as absolute RVFWLS <20%, and among the 388 patients (73%) with normal tricuspid annular planar systolic excursion and RV fractional area change, more than one-half showed impaired RV function. Lower values of RVFWLS and RVFWLS/PASP ratios were significantly associated with higher circulating N-terminal pro–B-type natriuretic peptide. With a median follow-up of 2.8 years, there were 277 total HF hospitalizations and cardiovascular deaths. Both absolute RVFWLS (HR: 1.39; 95% CI: 1.05-1.83; P = 0.018) and RVFWLS/PASP ratio (HR: 1.43; 95% CI: 1.13-1.80; P = 0.002) were significantly associated with the composite outcome. Treatment effect of sacubitril/valsartan was not modified by measures of RV function. Conclusions: Worsening RV function and its ratio to pulmonary pressure is common and significantly associated with an increased risk of HF hospitalizations and cardiovascular death in patients with HFpEF.
