Elevated Troponin T (TnT) in Non-acute Coronary Syndrome (ACS) Due to Dermatomyositis.

Troponin is a highly specific biomarker for myocardial injury. It plays a critical role in the diagnosis of acute coronary syndrome (ACS). However, elevated troponin levels are not exclusively due to cardiac ischemia and may be observed in many non-cardiac conditions, including inflammatory myopathies.
