Cineangiography of the coronary arteries: clinical function and anatomic correlation in patients with chronic chest pain.
Fifty French-Canadian patients presenting with typical or atypical anginal pain were studied by selective cinearteriography and coronary sinus catheterization, with measurement of myocardial function, oxygen and lactate extraction at rest and during isoproterenol infusion. In 28 of 42 patients all three coronary arteries were involved, but angina pectoris also occurred in patients with single mildly stenotic arterial lesions and even in eight patients with normal cinearteriograms. All patients with severe arterial lesions had typical angina, and the longer the duration of angina, the greater the extent, usually, of anatomic disease. Seventy-nine percent of resting electrocardiograms of patients with documented coronary artery disease were abnormal, with recognizable prior infarction in 18. Two-thirds of the patients experiencing pain during the stressful state had abnormal ventricular function. An abnormal arteriovenous lactate difference in response to isoproterenol occurred in patients in all groups.
