title: Cardiac assessment with thallium scanning prior to aortic aneurysm repair.
abstract: Coronary artery disease occurs commonly in patients with aortic aneurysms and is a major cause of morbidity and mortality. The role of screening and intervention for cardiac disease prior to aneurysm repair is controversial. The outcome after cardiac screening with thallium scanning and/or angiography in 102 consecutive patients undergoing aortic aneurysm repair was documented. Significant coronary artery disease was found in 34 (33%) patients and two patients had either coronary artery bypass or angioplasty prior to aneurysm repair. There was no cardiac mortality after aneurysm repair and the overall mortality on an intention-to-treat basis was 2%. There was good correlation between prior history of cardiac events, electrocardiography (ECG) and the results of screening with thallium scanning and angiography. There was no correlation between cardiac history, ECG and the incidence of cardiac events in the postoperative period. Significant coronary artery disease was found in 33% of patients without a cardiac history or abnormal ECG. Cardiac screening with thallium scanning confirmed a high incidence of significant coronary disease in patients with aortic aneurysm. In this study, cardiac intervention followed by expedient aneurysm repair in 20 patients was associated with zero mortality. The short-term benefit of such a policy is difficult to prove and its main advantage may be better long-term survival.
