The predictive value of anginal chest pain as an indicator of coronary disease during exercise testing.

To determine the significance of anginal chest pain during exercise testing, a series of 302 patients undergoing coronary arteriography with exercise testing was reviewed. Of the 302 patients, 85 had ischemic ECG changes and chest pain (Group I); 87 patients had ischemic ECG changes but no chest pain (Group II); 25 patients had chest pain but no ischemic ECG changes (Group III); 105 patients had neither chest pain nor ischemic ECG changes (Group IV). Coronary artery disease was present in 95% of Group I, 75% of Group II, 72% of Group III, and 28% of Group IV. Of those patients with coronary disease, multiple vessels were involved in 94% of Group I, 51% of Group II, 67% of Group III, and 21% of Group IV. The predictive value for presence and extent of coronary disease showed Group I greater than Groups II and III greater than Group IV (p less than 0.025). We conclude that (1) anginal chest pain during exercise testing predicts the presence and extent of coronary disease more accurately than its absence; (2) the presence of chest pain even without an ischemic ECG response during exercise testing appears to be as predictive of coronary disease as an ischemic ECG response alone; and (3) the combination of anginal chest pain during exercise testing and an ischemic ECG response is highly predictive of multivessel coronary artery disease.
