Outcomes in Patients Receiving Treatment for Pulmonary Arterial Hypertension Associated With Repaired Congenital Heart Disease
Bibliographic record
Abstract
BACKGROUND: Pulmonary arterial hypertension (PAH) is a common complication among patients with congenital heart disease (CHD). Despite advances in PAH treatment, evidence for the benefits of PAH therapies in CHD-PAH is limited. OBJECTIVES: This analysis aimed to evaluate outcomes in patients with repaired PAH-CHD receiving an approved PAH drug. METHODS: This was a pooled analysis including CHD-PAH patients whose CHD was repaired ≥1 year prior from 3 randomized, placebo-controlled, event-driven studies: GRIPHON (NCT01106014), SERAPHIN (NCT00660179), and COMPASS-2 (NCT00303459). The primary endpoint was time to first confirmed morbidity/mortality (M/M) event. HRs with 95% CIs were determined with random effects models. RESULTS: The analysis included 1,982 patients with PAH, 177 (8.9%) with CHD-PAH. In the overall PAH cohort, the mean age was 48 and 49 years in treatment and placebo groups; 80% and 77% were female. In the CHD-PAH cohort, the mean age was 41 and 39 years; 70% and 66% were female. Overall, ≥98% in each group were World Health Organization functional class II and III at baseline. There was a significant reduction in risk of M/M events vs placebo in the overall PAH and CHD-PAH cohorts: 37% reduction in the overall PAH cohort (HR: 0.63; 95% CI: 0.52-0.77) and 50% reduction in the CHD-PAH population (HR: 0.50; 95% CI: 0.26-0.94). CONCLUSIONS: Treatment with approved PAH drugs provided a similar reduction in M/M risk in patients with repaired CHD-PAH when compared with the overall PAH population. This pooled analysis provides important evidence to guide medical management in this patient population.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
