title: Angiographic concurrence of coronary artery disease and aortoiliac lesions.
abstract: The importance of recognizing the association between aortoiliac disease and coronary artery disease includes the following: (1) Long-term morbidity is higher and survival ratio poorer in patients with coronary heart disease compared with isolated lower extremity revascularization surgery. (2) Coronary artery bypass grafting is a relatively high-risk procedure in patients with severe vascular disease. (3) There is the prospect that the patient will eventually face simultaneous coronary artery and vascular surgery, or coronary artery angioplasty previous to aortoiliac surgery. The aim of this investigation is to know the frequency of the association of coronary artery disease with aortoiliac lesions and to stratify the risk factors related to such an association. In total, 65 men and 19 women (30 to 76 years of age) with a history of coronary heart disease underwent abdominal aortography after selective coronary artery and left ventricle angiography. Aortoiliac lesions were identified at angiograms. Relevant coronary artery disease was diagnosed when at least 1 coronary artery was obstructed > 50%. The frequency of association between aortoiliac and coronary artery lesions was established, as well as the relationship of these lesions to the following clinical variables: age, weight, height, smoking habit, history of coronary heart disease, systemic arterial hypertension, diabetes mellitus, intermittent claudication, glycemia, uricemia, and triglyceridemia. There were 36 patients (42.9%) with aortoiliac lesions. In 34 patients (40.5%) coronary artery disease was associated with aortoiliac lesions. Abdominal aortic dilations were found in 10 instances, abdominal aortic stenosis in 13 patients, and stenosis of the iliac arteries or their branches on 28 occasions. The variables statistically related to the presence of aortoiliac lesions were smoking habit and a history of intermittent claudication. The number of affected coronary arteries was directly related to the frequency of aortoiliac lesions. In the entire sample, 11 patients (13%) had no coronary artery disease, and 15 (17.9%) had 1-vessel, 24 (28.6%) 2-vessel, and 34 (40.5%) 3-vessel disease. The extent of coronary disease was directly related to the frequency and extent of aortoiliac lesions. Frequencies of aortoiliac lesions were strongly related to a history of smoking habit and intermittent claudication and directly related to the extent of coronary artery disease.
