Among selected patients undergoing major noncardiac surgery, beta-adrenergic blockade has been shown to reduce the risk for postoperative cardiac complications and mortality. We sought to determine how often postoperative MI might be considered preventable through appropriate use of these medications. ⋯ A large percentage of the postoperative MIs at our institution might have been prevented if a beta-blocker had been administered to all ideal candidates around the time of surgery. Use of beta-blockers before infarction may reduces overall mortality, even among patients who go on to develop this complication.
