Algorithms for preoperative cardiac evaluation prior to noncardiac surgery use indices of the metabolic equivalent of activities of daily living (METs). We evaluated METs as a predictor of cardiac complications following elective, noncardiac surgery. ⋯ METs are not a reliable index for the prediction of adverse cardiac events following elective, noncardiac surgery. Age and physical status are more predictive. Adverse cardiac outcomes are most frequent following vascular surgery.
