Utility of pre-catheterisation high-sensitivity troponin T in patients without obstructive coronary artery disease

Myocardial infarction (MI) in patients subsequently shown to have no obvious, or trivial coronary artery disease (<50% stenosis) at angirography is seldom studied, but may be attributable to either a primary coronary event or, less commonly, type 2 MI. Recently developed, high-sensitivity troponin T (hs-TnT) assays have increased sensitivity for detection of minor degrees of myocardial necrosis, improving MI detection rate. We assessed the prognostic utility of pre-catheterisation hs-TnT in patients without angiographically significant coronary narrowing.
