Incidence and trends of cardiac complications in major abdominal surgery

Myocardial infarction or cardiac arrest after major abdominal surgery increased the odds of mortality with superior rescue after cardiovascular complications at higher volume institutions. Across all US hospitals performing major abdominal surgery, the rate of cardiac arrest increased without a concomitant increase in myocardial infarction or mortality. Novel targets for risk modification of myocardial infarction and cardiac arrest as well as investigation of processes that facilitate rescue after these complications at higher operative-volume hospitals are needed to delineate quality improvement opportunities.
