Perioperative beta blocker exposure was associated with a lower rate of mortality among high-risk patients undergoing noncardiac, nonvascular surgery, according to a study in the Journal of the American Medical Association.
Researcher analyzed the all-cause, 30-day mortality rate among 136,745 patients at 104 VA medical centers between January 2005 and August 2010. Overall, 55,138 patients (40.3 percent) were exposed to beta blockers.
Among patients with two or more revised cardiac risk index factors, exposures to beta blockers during surgery was found to be associated with lower mortality rates.
