Perioperative β-blockers in high-risk patients

One major risk to patients in the preoperative period is that of myocardial ischemia or infarction and cardiovascular death in high-risk patients. Historically, attempts to decrease the incidence of perioperative cardiac complications have focused on preoperative evaluation and identification of patients at risk for complications with referral for additional testing and/or revascularization. Evidence suggests that the use of perioperative β-blockers in high-risk individuals can reduce the incidence of perioperative cardiac events. The Agency for Healthcare Research and Quality has identified that the use of perioperative β-blockers can reduce perioperative morbidity and mortality. The focus of this article is to describe the evidence supporting perioperative β-blocker use, to discuss potential barriers to their use, and to propose a strategy to improve their use.
