Kaplan–Meier Survival Analysis Comparing Pre-Capillary Pulmonary Hypertension to Rest. Kaplan Meier survival analysis comparing COPD-PH patients with pre-capillary PH (defined as mPAP > 20 mmHg, PAWP ≤ 15 mmHg, and PVR ≥ 2 WU), to those without pre-capillary PH, encompassing post-capillary PH, combined pre- and post-capillary PH, and unclassified PH. Post-capillary PH is defined as mPAP > 20 mmHg, PAWP > 15 mmHg, and PVR ≤ 2 WU. Combined pre- and post-capillary PH is defined as mPAP > 20 mmHg, PAWP > 15 mmHg, and PVR > 2 WU. Unclassified PH is defined as mPAP > 20 mmHg, PAWP ≤ 15 mmHg, and PVR ≤ 2 WU. Similar transplant waitlist survival probability observed between the two groups. Number of COPD-PH patients in each group at risk of death displayed on the bottom, with changes in curves reflective of patients who suffered waitlist mortality. COPD Chronic obstructive pulmonary disease. mPAP Mean pulmonary artery pressure. PAWP Pulmonary artery wedge pressure. PH Pulmonary hypertension. PVR Pulmonary vascular resistance
