Abstract:
Objective To investigate the association of chest pain patients with primary level in high-sensitivity troponin T (hs-cTnT) level no more than 14 ng/L in the onset of acute myocardial infarction in pa-tients with chest pain. Methods We enrolled 3 096 participants from January 2012 to December 2013 in West China Hospital, Sichuan University. All patients were classified two groups (hs-cTnT > 14 ng/L, hs-cTnT ≤14 ng/L and no ischemia on ECG) according to hs-cTnT levels and ECG. We evaluated the risk of myocardial in-farction and death and negative predictive value in 30 days. Results Thirty-seven patients were diagnosed in having acute myocardial infarction (AMI) and 4 patients were dead in the hs-cTnT > 14 ng/L group in 30 days in the absolute risk 2.35(1.86-2.74) and 0.29(0.12-0.53); 9 patients were diagnosed as having AMI and no patients were dead in the hs-cTnT ≤ 14 ng/L group in 30 days in the absolute risk 0.58 (0.42-0.74). Conclu-sion Chest pain patients whose primary levels no more than 14 ng/L in hs-cTnT with no ischemia on ECG can be ruled out AMI in negative predictive value 99.6%. the levels of hs-cTnT which were dynamic monitored at least 5 h and still no more than 14 ng/L can rule out AMI directly.
