Observations on exercise testing and coronary arteriography.

Exercise tests were performed on 551 patients with a clinical diagnosis of coronary artery disease during their admission for angiography. A computer-generated index (CI, 0-100%) was used to describe the coronary anatomy, and additional data on left ventricular contraction abnormalities were recorded. Significant correlations exist between exercise performance and angina grade, coronary pathology, left ventricular function, and prognosis.
