Investigations, findings, and follow-up in patients with chest pain and elevated high-sensitivity cardiac troponin T levels but no myocardial infarction.

Background: Elevated troponin levels, in patients without myocardial infarction (MI), are associated with increased mortality. In an observational cohort study we aimed to assess how patients with elevated high-sensitivity cardiac troponin T (hs-cTnT) levels, and no MI are investigated and followed up, compared to patients with MI.

Methods: During January 1, 2011 to December 31, 2012, all patients >25years of age, with chest pain and elevated hs-cTnT levels or MI, at the Karolinska University Hospital were included.
