Serum Cardiac Troponin T Levels in Asymptomatic Elderly Nursing Home Residents.

The American journal of medicine Dec 27, 2017
BACKGROUND: The definition of myocardial infarction relies on elevated troponin levels. However, elevated levels of high sensitive cardiac troponin (hs-cTnT) assays have been reported in elderly patients without acute myocardial infarction. We sought...
