The benefit versus risk of perioperative beta blockade therapy for adverse ischemic event risk reduction in high risk patients undergoing non-cardiac surgery has been recently challenged. In particular the PeriOperative Ischemia Study Evaluation (POISE trial) showed a cardio-protective effect only at the expense of a higher incidence of stroke and all-cause mortality . In that study death and stroke were significantly associated with an increase in hypotension and bradycardia. Long acting agents - aggressively administered to achieve heart rate (HR) control - appear to be associated with significant adverse outcomes (death, stroke) despite myocardial ischemia and infarction reduction.
