Purpose Of Review:
Although the indications for β-blockers in the management of patients with congestive heart failure and myocardial infarction are well established, the use of β-blockers in the perioperative setting remains controversial.
Recent Findings:
Since 2008 PeriOperative ISchemic Evaluation Trial, there have been numerous studies suggesting that perioperative β-blockers are associated with adverse events such as hypotension, bradycardia, increased mortality, and stroke.
Summary:
In this article, we review the most recent evidence to suggest an approach to perioperative β-blocker use tailored to patient and surgical risk factors. We also review recent studies on off-label uses for perioperative β-blockers.
