We reviewed Spirometric data from 8 patients with primary pulmonary hypertension and from 17 patients with chronic thromboembolic pulmonary hypertension. All patients had undergone right heart catheterization and pulmonary angiography. Five of the 8 patients with primary pulmonary hypertension demonstrated a severe restrictive ventilatory pattern with a mean vital capacity (VC) of 50.4% predicted and a mean total lung capacity (TLC) of 64.3% predicted. Five of the 17 patients with chronic thromboembolic pulmonary hypertension manifested a restrictive pattern with a mean VC of 68.0% predicted and a mean TLC of 75.3% predicted. We conclude that restrictive ventilatory defects occur more frequently than previously described in patients with PPH. The physiologic mechanism responsible for the restrictive ventilatory pattern is not clear.<\/jats:p>","DOI":"10.1164\/arrd.1983.128.1.163","type":"journal-article","created":{"date-parts":[[2015,10,4]],"date-time":"2015-10-04T22:51:18Z","timestamp":1443999078000},"page":"163-165","source":"Crossref","is-referenced-by-count":41,"title":["Restrictive Ventilatory Pattern in Precapillary Pulmonary Hypertension"],"prefix":"10.1093","volume":"128","author":[{"given":"Matthew","family":"Horn","sequence":"first","affiliation":[{"name":"Requests for reprints should be addressed to Kenneth M.
