Abstract/OtherAbstract:
Equilibrium radionuclide angiocardiography (ERNA) was employed preoperatively in 183 patients undergoing elective abdominal aortic reconstruction to measure left ventricular ejection fraction (LVEF) and to detect abnormal regional wall movement. Abnormal ejection fractions were virtually confined to the 97 patients who had clinical, electrocardiographic or radiographic evidence of heart disease. An operative mortality of 8.7% was recorded. Major cardiac events (defined as myocardial infarction, cardiac failure or malignant ventricular arrhythmia) occurred in 15 of 86 abdominal aortic aneurysm patients (17.4%) and six of 96 (6.25%) patients with aorto-iliac occlusive disease. Patients with an abdominal aortic aneurysm and abnormal LVEF or regional wall motion abnormality were more likely to suffer a cardiac event (p less than 0.001), the event rate exceeding 60% in patients whose LVEF was less than 35%. An abnormal LVEF failed to predict a cardiac event in patients with aorto-iliac occlusive disease. While not indicated in patients lacking clinical evidence of heart disease, ERNA can refine the assessment of cardiac risk, particularly in patients with previous myocardial infarction and define a high risk group in whom aortic reconstruction should be avoided except for the most compelling of indications.
