Protein made during long workouts may warn of heart problem

Doctors diagnose heart attacks by looking for a specific protein the heart releases when damaged. Now, researchers have found higher levels of the same protein among some long-distance walkers – and they were more likely ...

Novel troponin assay, hs-cTnI comparable in ruling out AMI

(HealthDay)—A single point-of-care troponin concentration measured on arrival to the emergency department (ED) with 15-minute turnaround time can accurately rule out acute myocardial infarction (AMI), according to a study ...
