A study published in the June 2011 issue of Anesthesiology assessed the risk factors associated with postoperative stroke in patients undergoing non-cardiac surgery, according to a release.
According to the release, stroke is the leading cause of death in the United States and is known to occur after surgeries — even those that do not involve the heart or brain. In this study, researchers at the University of Michigan used a national database to study the incidence, predictors and outcomes associated with postoperative stroke. The researchers analyzed the records of more than 500,000 non-cardiac and non-neurologic patients to determine the frequency of stroke and the characteristics of at-risk patients.
The study identified risk factors including myocardial infarction, acute renal failure, past history of stroke, dialysis and hypertension. The researchers also found that stroke was associated with an eight-fold increase in postoperative mortality within 30 days.
The authors were able to develop a "risk index classification" to help clinicians assess patients at risk for postoperative stroke.
