Prognostic value of pulmonary vascular resistance (PVR) in pulmonary hypertension (PH) caused by interstitial lung disease (ILD). (A) Kaplan-Meier survival curve stratified by the current hemodynamic definition of severe PH in lung disease: mean pulmonary arterial pressure (mPAP) ⩾ 35 mm Hg or mPAP ⩾ 25 mm Hg with cardiac index <2.0 L/min/m2. (B) Kaplan-Meier survival curve stratified by PVR ⩽ 5 WU and PVR > 5 WU. (C) Kaplan-Meier survival curve stratified by PVR ⩽ 8 WU and PVR > 8 WU. WU = Wood units.
