[Angiographic morphology of coronary lesions in various syndromes of ischemic cardiopathy].
The angiographic morphology of coronary lesions is often completely ignored in the prognostic and decision-making process related to patients with coronary disease. We performed this study to evaluate the possibility of identifying complex or complicated atherosclerotic lesions by means of routine diagnostic coronary arteriography, and to assess their prevalence in the different syndromes of ischaemic heart disease. From an overall group of 200 successive cases studied using coronary angiography, 111 patients with significant coronary artery disease in whom a "culprit lesion" could be identified were retrospectively selected. The angiographic morphology of coronary lesions was defined according to an original classification as: 1) simple stenosis, 2) complex lesion, 3) thrombosis. Of the 111 patients, 36 had been studied for stable angina, 31 for unstable angina, 10 for a non-Q wave myocardial infarction, 34 for transmural infarction. The clinical groups did not show any significant differences when compared on the basis of number of vessels involved and degree of narrowing of the ischaemia-producing artery. Significant differences were found when angiographic morphology was analyzed. In stable angina 78% of ischaemia producing lesions appeared as simple stenoses, while 92% of the unstable or more severely ischaemic patients exhibited complicated lesions (p less than 0.001). In unstable angina and non-Q infarction a complex lesion was present respectively in 71% and 60% of the cases; clear-cut intraluminal thrombosis was demonstrated in 23% of unstable angina, in 30% of non-Q wave infarction and in 39% of transmural infarction (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
