Kaplan–Meier analysis in PH-LHD, Cpc-PH and Ipc-PH patients stratified by peak VO2/kg. A Survival in PH-LHD patients between the peak VO2/kg ≥ 10.7 ml kg−1 min−1 and peak VO2/kg < 10.7 ml kg−1 min−1. B Survival in PH-LHD patients between Cpc-PH and Ipc-PH. C Survival in Cpc-PH patients between the peak VO2/kg ≥ 10.7 ml kg−1 min−1 and peak VO2/kg < 10.7 ml kg−1 min−1. D Survival in Ipc-PH patients between the peak VO2/kg ≥ 10.7 ml kg−1 min−1 and peak VO2/kg < 10.7 ml kg−1 min−1. Survival analyses were compared by the log-rank test. VO2, oxygen uptake; PH-LHD, pulmonary hypertension due to left heart disease; Cpc-PH, post- and precapillary pulmonary hypertension; Ipc-PH, isolated postcapillary pulmonary hypertension
