High-Dose β-Blockers and Tight Heart Rate Control Reduce Myocardial Ischemia and Troponin T Release in Vascular Surgery Patients

Abstract

Background— Adverse perioperative cardiac events occur frequently despite the use of beta (β)-blockers. We examined whether higher doses of β-blockers and tight heart rate control were associated with reduced perioperative myocardial ischemia and troponin T release and improved long-term outcome.
