Abstract
The coronary blood flow was determined in 9 individuals with pulmonary emphysema alone and emphysema with cor pulmonale. Intracardiac pressures, cardiac output and pulmonary functions were also studied. In 8 of the 9 cases coronary blood flow was within the normal range. In one case with a high cardiac output the coronary blood flow was elevated in proportion. The presence of cor pulmonale did not appear to influence the results.
