Abstract | OBJECTIVE: METHODS: RESULTS: One patient was lost to follow up and one patient died. Systolic pulmonary artery pressure showed no significant changes at 2 (93.6 ± 17.2 mmHg) and 4 months (85.7 ± 25.5 mmHg) of bosentan treatment compared to that before the medication (97.8 ± 14.9 mmHg) (P=0.096), but decreased significantly after a 6-month therapy (80.9 ± 25.0 mmHg, P=0.029). The 6-minute walking distance increased significantly after a 2, 4, and 6-month therapy [(488 ± 98.8, 496.3 ± 89.0, and 491.3 ± 114.2 m, respectively; P=0.004, 0.003, and 0.004 vs the distance before medication (317.0 ± 134.1)]. The New York heart functional classification was improved significantly after a 2, 4, and 6-month therapy [(2.0 ± 0.5, 1.8 ± 0.4, and 1.7 ± 0.5, respectively; P<0.001 vs pre-medication score (2.9 ± 0.5)). Hepatic and renal function remained normal, and ALT and AST showed no significant variations during the medication (P>0.05). CONCLUSION: Oral bosentan can effectively relieve the symptoms, decrease pulmonary artery hypertension, and improve exercise tolerance and cardiac function classification in patients with pulmonary artery hypertension associated with congenital heart disease with good safety and mild side effects.
