BACKGROUND: Noncardiac surgery is associated with significant cardiovascular mortality, morbidity, and cost. Small trials of beta-blockers suggest that they may prevent cardiovascular events in patients undergoing noncardiac surgery, but trial results are inconclusive.

METHODS: The POISE trial is a blinded, randomized, and controlled trial of controlled-release metoprolol versus placebo in 10000 patients at risk for a perioperative cardiovascular event who are undergoing noncardiac surgery. Patients will receive the study drug 2 to 4 hours before surgery ..View full abstract
