[Beta-blocker therapy and risk reduction in non-cardiac surgery].
Cardiovascular complications are important causes of morbidity and mortality with major noncardiac procedures. Preoperative cardiac evaluation aims at assessing the patient's clinical risk profile in order to provide the more cost-effective strategy to reduce the risk of cardiac complications. Among different ways to reduce the incidence of perioperative cardiac complications, compelling evidence comes from the use of beta-blockers: in the absence of absolute contraindications, beta-blocker therapy should be administered to all patients at intermediate-high risk for coronary events who have to undergo noncardiac surgery. Even if the number of patients enrolled in these studies is relatively small, the use of beta-blockers before noncardiac surgery has been shown to be associated with a significant reduction in major cardiac events so that this therapy may reduce the need for additional noninvasive tests in some groups of patients. Coronary angiography and revascularization should have the same indications as if performed in the nonoperative setting.
