title: [Quantitative analysis of coronary arteriogram by a computer-assisted method].
abstract: A computer-assisted method for quantitating coronary arteriograms was applied to measure the diameter of major epicardial coronary arteries in 58 normal subjects and 25 hypertensive patients, and to determine the percentage of relative stenosis of coronary lesions in 109 patients with coronary artery disease. Average coronary size was larger than normal in patients with hypertension. The left coronary artery was larger than the right coronary artery in the majority of patients. The degree of coronary stenosis can be measured accurately with good reproducibility. Thus this inexpensive microprocessor system provides rapid quantitation of coronary artery diameter and lesions.
