Objective: To assess the efficacy of epoprostenol treatment in Japanese patients with pulmonary arterial hypertension (PAH) associated with connective tissue disease (CTD). Methods: Sixteen patients with PAH-CTD treated with continuous intravenous epoprostenol at a single center between 2000 and 2009 were enrolled. Baseline characteristics, short-term and long-term outcomes, predictors of mortality, and safety profiles were evaluated. For survival analysis, 16 controls were selected who matched the underlying CTD, World Health Organization functional class, and use of PAH drugs, except for epoprostenol. Results: Six patients had systemic lupus erythematosus, five had mixed CTD, four had systemic sclerosis, and one had primary Sjögren's syndrome. The mean pulmonary arterial pressure (mPAP), cardiac index (CI), pulmonary vascular resistance, and functional class were significantly improved during the first 6 months of epoprostenol treatment. Cumulative survival rates at 1, 2, and 3 years in epoprostenol-treated patients were 69, 69, and 55 %, respectively, and were significantly better than those of the controls. Functional class, CI at baseline, and reduction of mPAP at 6 months were identified as predictors of survival. Adverse events, including flushing and catheterrelated infection, were frequent, but all patients tolerated the treatment. Conclusion: Based on the improvements in both shortterm and long-term outcomes among our patient cohort, epoprostenol is an effective treatment for CTD patients with advanced PAH.
