Postop Troponin Levels May Peg Risk for Death
Measuring peak fourth-generation troponin levels after noncardiac surgery may help predict which patients have a greater risk of dying within 30 days, researchers found.
Patients who had a peak troponin value of at least 0.02 ng/mL in the first 3 postoperative days were significantly more likely to die than those with a value of 0.01 ng/mL or less, according to P.J. Devereaux, M.D., Ph.D., of McMaster University's Population Health Research Institute in Hamilton, Ontario, and colleagues.
Adding postoperative peak troponin measurements to a model based on preoperative factors enhanced discrimination and risk classification, the researchers reported in the June 6 issue of the Journal of the American Medical Association.
