[Coronary artery disease in patients with abdominal aortic aneurysm].

Selective coronary angiography to determine the prevalence of coronary artery disease (CAD) has been performed in patients with abdominal aortic aneurysm (AAA). Thirty patients in this series consisted of 26 men and 4 women with an age range of 48-87 years (mean +/- SD: 67.5 +/- 8.2 years). As the atherosclerotic risk factors, cigarette smoking was present in 19 patients (63.3%), hypertension was in 18 (60%), hypercholesteremia was in 10 (33.3%), and diabetes mellitus was in 2 (6.7%). Cerebral vascular disease was present in 11 patients (36.7%). Regarding CAD, angina pectoris or old myocardial infarction was found in 9 patients (30%), and abnormal electrocardiography (ECG) was in 16 patients (53.3%). Coronary angiography prior to operation of AAA was performed to 22 patients (73.3%), and 15 patients (68.2%) among them had significant coronary artery stenosis, and 9 patients underwent myocardial revascularization (4 CABG, 5 PTCA). CAD was frequently complicated both in patients without symptoms or ECG abnormalities and in less than 65-year patients. In order to prevent fatal myocardial infarction, we recommend routine coronary angiography to patients with AAA. And if necessary, myocardial revascularization must be indicated prior to aneurysmectomy.
