The Use of Preoperative Aspirin in Cardiac Surgery: A Systematic Review and Meta-Analysis

This is a meta-analysis of perioperative aspirin use. Preoperative aspirin use increased bleeding risk, but it did not increase the need for reexploration or red cell transfusion if the preoperative dose was lower than 160 mg/d.  Aspirin use was associated with decreased mortality, acute kidney injury, and perioperative myocardial infarction.
