A total number of 177 patients with coronary lesions were studied. Sixty nine of them presented either a combination of stenotic and ectatic lesions (n = 18) or isolated ectatic lesions (n = 51) and 108 presented only stenotic lesions. Analyzing several clinical and epidemiological parameters we observed a significant difference with respect to the higher prevalence of hypertension among the group affected by ectatic lesions. We verified as well a higher prevalence of myocardial infarction in the group of ectasia associated to the stenotic lesions. Finally, a higher global mortality was observed in the group of ectasia associated to stenotic lesions after medical or surgical treatment
