An original model for estimating myocardial ischaemia from coronary arteriography is proposed. Four parameters are taken into consideration: anatomical variations, the myocardial mass perfused, the degree of reduction of basal flow across the stenosis, the eventual summation of several successive stenotic lesions. This scoring system was tested by simulation on a computer and evaluated in 100 anginal patients. Analysis of our preliminary results shows statistically significant differences in the score between the following groups of patients: patients with normal and those with abnormal LV wall motion; patients with and those without previous myocardial infarction; patients with Class II stable angina and those with other forms (III, IV and unstable angina).
