The Ischemic Exercise Test in Patients With Peripheral Vascular DiseaseImplications for Management

Arch Surg. 1984;119(7):780-783. doi:10.1001/archsurg.1984.01390190024005

• We observed myocardial ischemia in 135 of 808 patients undergoing routine ECG-monitored treadmill tests before vascular reconstructive operations. Postoperative infarction incidence was 27% among 56 patients who had operations regardless of test results. When patients had a lesser procedure, such as extra-anatomic bypass, infarction incidence decreased to 17% (not statistically significant). Ten patients having staged aortocoronary and peripheral reconstruction had no myocardial infarctions postoperatively or during follow-up of up to five years. Of 37 patients asymptomatic for coronary artery disease who had normal ECGs at rest, 24% of those undergoing a standard intra-abdominal operation suffered myocardial infarctions. At present, such asymptomatic but high-risk patients can be identified only by routine ECG stress testing or coronary angiography. Patients with an ischemic response to exercise have the best chance for long-term survival through staged coronary and vascular reconstruction.
