[Incidence and risk factors of coronary artery disease in elderly patients with abdominal aortic aneurysm]

To explore the prevalence of coronary artery disease and risk factors in patients with abdominal aortic aneurysm (AAA).Coronary angiography was performed immediately after abdominal angiography in 70 elderly (50 years) consecutive patients with AAA. Medical history and imaging characteristics were evaluated.CAD was diagnosed in 63 patients (90.0%) by coronary angiography: 20 (28.6%) patients with single-vessel disease (SVD), 15(21.4%) with 2VD, 22 (31.4%) with 3VD and 6 (8.6%) with left main disease + 3VD. Multi-variance logistic analysis showed that peripheral disease was the strongest predictor for CAD in AAA patients.Coronary angiography should be performed in elderly AAA patients due to the high prevalence of CAD in this patient cohort.
