KEY FINDINGS
-
Clonidine had no effect on death or myocardial infarction. Clonidine was associated with an increased risk of non-fatal cardiac arrest and hypotension.
-
ASA had no effect on death or myocardial infarction, but increased the risk of major and life-threatening bleeding.
-
POISE 2 demonstrated that clinicians can improve outcomes by holding ASA during the perioperative period.
-
Perioperative hypotension and major/life threatening bleeding were independent predictors of perioperative myocardial infarction.
