Q. A 23-year-old female complains of dyspnea and substernal chest pain on exertion. Evaluation for this complaint 6 months ago included arterial blood gas testing, which revealed pH 7.48, PO2 79 mmHg, and PCO2 31 mmHg. Electrocardiography then showed a right axis deviation. Chest x-ray now shows enlarged pulmonary arteries but no parenchymal infiltrates, and a lung perfusion scan reveals subsegmental defects that are thought to have a “low probability for pulmonary thromboembolism.” Echocardiography demonstrates right heart strain but no evidence of primary cardiac disease. The most appropriate diagnostic test now would be

A. open lung biopsy
B. Holter monitoring
C. right-heart catheterization
D. serum α1-antitrypsin level

Post your answer to see the correct answer and explaination.
