ObjectiveTo evaluate the validity of preoperative cardiac stress testing using clinical predictors from the American College of Cardiology/American Heart Association Guidelines on Perioperative Evaluation before Noncardiac Surgery in patients undergoing vascular surgery.DesignProspective, randomized pilot study.SettingAcademic medical center.ParticipantsPatients undergoing elective abdominal aortic, infrainguinal, and carotid vascular surgery.InterventionsAfter stratification by American College of Cardiology/American Heart Association (ACC/AHA) Guideline parameters, 99 patients were randomized to preoperative cardiac stress testing or to no stress testing and followed for up to 12 months postoperatively for adverse cardiac outcomes.Measurements And Main ResultsBefore hospital discharge of 46 patients who underwent preoperative stress testing, 7 (15%) had inducible ischemia with no adverse postoperative cardiac outcomes, whereas only 1 (3%) of 39 patients (85%) with no ischemia had a nonfatal adverse cardiac outcome (p = not significant). Of 53 patients without preoperative stress testing, only 2 (4%) had a nonfatal adverse postoperative cardiac outcome. There were no cardiac deaths. At 12-month follow-up in 79 (80%) patients, there was 1 nonfatal adverse cardiac outcome (no stress test) and 1 cardiac death (abnormal stress test), reflecting a 1% 12-month cardiac morbidity and mortality.ConclusionIn this small prospective, randomized study evaluating the validity of preoperative cardiac stress testing using ACC/AHA Guidelines before major vascular surgery, preoperative cardiac stress testing offered no incremental value for determining postoperative adverse cardiac outcomes. Larger randomized clinical trials are needed to confirm these findings.
