Dobutamine Stress Echocardiography Prior to Aortic Surgery: Long-Term Cardiac Outcome

This study was undertaken to evaluate the efficacy of dobutamine stress echocardiography (DSE) in predicting not only perioperative but also long-term cardiac events. One hundred fifty-nine patients who were evaluated for elective abdominal aortic surgery were screened preoperatively with DSE from January 1, 1992 to December 31, 1993. We concluded that DSE is useful for preoperative assessment of cardiac risk prior to elective aortic surgery to minimize the need for cardiac intervention and still maintain acceptable perioperative Ml and death rates. A selective approach for coronary revascularization is justified by the higher mortality in the subgroup requiring sequential procedures. DSE also allowed us to identify those high-risk patients who are best excluded from aortic surgery. Patients with abnormal DSE results are at higher risk for late cardiac events, require cardiology follow-up, and may require late coronary intervention.
