title: Predictive value of manual ECG-monitored exercise test before abdominal aortic or peripheral vascular surgery.
abstract: The value of manual ECG-monitored exercise test was studied in 58 patients (39 men and 19 women) with intermittent claudication scheduled for abdominal or peripheral vascular surgery. There was a high incidence of well-known risk factors (hypercholesterolemia, smoking, and hypertension) in men and women. History of coronary artery disease (CAD) was present in 29.3% of the patients. No correlation was found between patients with single or multiple stenoses in lower extremity arteries (angiography) and CAD. Ischemic response (ECG) to manual exercise testing was positive in 14 patients (24.1%), of whom 2 (14.3%) had major cardiovascular postoperative complications. Both died of acute myocardial infarction within fourteen days. They had slow recovery (thirty to sixty minutes) of the ST segment (0.3-0.6 mV). The authors conclude that manual exercise testing might reveal serious CAD in patients with severe occlusive peripheral arterial disease of the lower extremities. In cases with slow recovery of ischemic response to exercise, coronary bypass or angioplasty could be advantageous before major vascular surgery.
