Kaplan-Meier curves for mortality by pulmonary arterial compliance (PAC) and pulmonary artery wedge pressure (PAWP) in patients with elevated mean pulmonary artery pressure in the primary cohort. (A) From the primary cohort, a Kaplan-Meier analysis was performed to determine the probability of all-cause mortality stratified by dichotomous PAC (PAC ⩾3.0 ml/mm Hg vs. <3.0 ml/mm Hg) in patients with mPAP ⩾19 mm Hg. (B and C) This population was then subgrouped by PAWP ⩽15 mm Hg (B) and PAWP >15 mm Hg (C). Results from a log-rank test comparing strata are provided for each analysis. Censoring begins at and beyond 1 year after the index right heart catheterization, represented here as Day 0. Number of patients at risk are provided at every 2-year interval after right heart catheterization. Solid lines represent kernel density. Dotted lines represent hazard ratio of 1.
