BACKGROUND: Pulmonary arterial hypertension associated with adult congenital heart disease (PAH-ACHD) leads to significant mortality at a young age. Risk factors for a negative outcome in older adults are lacking.
METHODS: PAH-ACHD patients ≥ 40 years of age under active follow-up between January 2005 and December 2018 were included. Demographic data, as well as medical/surgical history, were retrieved from hospital records. The primary end-point was all-cause mortality.
RESULTS: In total, 65 patients (67.7% female, mean age 45.19 ± 6.75 years) were included. Out of these, 46 (70.8%) had a shunt lesion, 12 (18.5%) had PAH associated with complex congenital heart defects, and 7 (10.8%) had segmental pulmonary hypertension due to major aorto-pulmonary collaterals. Down syndrome was present in 13 patients (20.0%). During a median follow-up of 4.2 years (IQR 1.2-7.5), 16 patients (24.6%) died. On univariate analysis, NT-proBNP (log), creatinine, and a previous history of ventricular arrhythmias were predictors of all-cause mortality. Upon multivariate analysis, NT-proBNP (log) (HR: 4.1, 95% CI: 1.2-14.4, p = 0.029) and creatinine (HR: 16.3, 95% CI: 2.2-118.7, p = 0.006) remained as independent predictors of all-cause mortality.
CONCLUSIONS: PAH-ACHD patients over the age of 40 years are burdened with significant mortality, of which NT-proBNP and creatinine are independent predictors.
