Intraoperative hypotension has been associated with cardiovascular events after non-cardiac surgery. However, whether avoiding intraoperative hypotension can reduce the incidence of postoperative cardiovascular events remains unclear. The objective of this study is to assess the effects of an intensive intraoperative blood pressure management strategy (to maintain intraoperative MAP 80mmHg) with that of conventional practice (to maintain intraoperative MAP 65mmHg) on the incidence of cardiovascular events after major abdominal surgery.
