High-sensitivity cardiac troponin T is a predictor of recurrent acute coronary syndrome in patients with acute myocardial infarction

Abstract

High-sensitivity cardiac troponin T is a useful tool for diagnosing myocardial ischemia. However, its role in the prognosis of patients with acute myocardial infarction has not been studied. Here, the prognostic value of high-sensitivity cardiac troponin T for patients with acute myocardial infarction was investigated. The concentrations of high-sensitivity cardiac troponin T, other clinical chemistry makers, and living habits were investigated at the time of admission in patients with acute coronary syndrome, whereas the high-sensitivity cardiac troponin T concentrations at 6 h after admission and during recovery were analyzed in other patient groups. The concentration of high-sensitivity cardiac troponin T was significantly higher in patients with acute myocardial infarction than in those with other cardiac diseases and in controls (P < 0.01). Based on the standard diagnostic criterion, 134 patients were diagnosed with acute myocardial infarction. Monitoring the change in concentration of high-sensitivity cardiac troponin T in patients with acute coronary syndrome can reduce the risk of recurrence and death. © FUNPEC-RP.
