title: Perioperative use of β-blockers in cardiac and noncardiac surgery.
abstract: OBJECTIVE
  Are β-blockers associated with lower rates of mortality and morbidity after cardiac or noncardiac surgery?
  
  
  CONCLUSIONS
  In cardiac surgery, β-blockers are associated with a lower incidence of supraventricular tachycardias (SVTs) and ventricular arrhythmias. In noncardiac surgery, β-blockers are associated with a possible increase in mortality and strokes, a lower incidence of acute myocardial infarctions (AMIs) and SVTs, and an increase in bradycardia and hypotension. If tolerated, long-term β-blocker treatment should be continued perioperatively, whereas the decision to start a β-blocker should be individualized, weighing risks and benefits.
