A-B, Kaplan-Meier curves showing that ACEI or ARB use is associated with decreased mortality in veterans with pulmonary hypertension. A, Outcome of mortality for ACEI or ARB users and nonusers for the full cohort (14,912 users and 9,309 nonusers). Five-year mortality in ACEI or ARB users was 35.0% (5,212 events) compared with 41.2% in nonusers (3,837 events). χ² = 154.8. B, Outcome of mortality for the propensity-matched cohort (7,480/group). ACEI or ARB use was defined as use of either medication class within 90 days of right heart catheterization. χ² = 65.8. Group comparisons were performed by log rank test. ACEI = angiotensin converting enzyme inhibitor; ARB = angiotensin receptor blocker.
