Abstract：Objective The aim of this study was to evaluate the diagnostic value of rule-out strategy for acute myocardial infarction (AMI) in chest pain patients with normal high-sensitivity troponin T (hs-cTnT).Methods Adults presenting chest pain to the West China hospital of Sichuan university from January 2016 to January 2017 were enrolled.Clinical data including ECG and hs-cTnT concentration was obtained.The diagnostic value of three strategies were evaluated.The optimal rule-out strategy for AMI were finally established in chest pain patients.Results A total of 153 patients were enrolled.In patients with chest pain time less than 5 h,the first hscTnT level was less than 14 ng/L.The negative predictive value (NPV) of 0/3 h dynamic observation and 5 minus the time of chest pain were 100％.The NPV was 99.8％ to rule-out AMI directly using the first hs-cTnT level.Conclusions For patients with chest pain time less than 5 h,the first hs-cTnT level less than 14 ng/L,0/3 h dynamic observation and the strategy of 5 h minus chest pain time have the same diagnosis value for ruling out AMI alternatively.It was not suggested to use the first hs-cTnT level to rule out AMI .
