In patients with pulmonary arterial hypertension (PAH) combination therapy with intravenous PG12 may lead to greater disease burden, finds study.
Researchers from Massachusetts General Hospital and Novartis Pharma AG in Switzerland performed statistical tests on 446 patients with PAH, of which (a) 337 were receiving monotherapy; (b) 88 were receiving non-IV PGI2 combination therapy; and (c) 21 were receiving IV PGI2 combination therapy. Results showed that pulmonary vascular resistance, mean number of PAH-related hospitalizations, and dyspnea scores were highest in those treated with IV PGI2. This study was presented during CHEST 2012, the annual meeting of the American College of Chest Physicians, held October 20 - 25, in Atlanta, Georgia.
