Abstract:
Objective To investigate the value of emergency observation time of chest pain patients for ruling-out myocardial infarction by using high-sensitive troponin T. Method Total 1 687 patients with chest pain from December 2015 to August 2016 visiting Sichuan University Huaxi Hospital emergency department were en-rolled.We included 1082 patients who diagnose with AMI finally.We define the time from the start of the chest pain to visiting the emergency as the onset time.We analyzed the level of high-sensitive troponin T of AMI patients at dif-ferent onset time and calculated the rate of patients with hs-cTnT level lower than the conventional hs-cTnT thresh-old of 14 ng/L. Result Among 1082 cases of AMI patients,32 patients with hs-cTnT level below threshold(14 ng/L).The for whose The onset time over 5h was observed in AMI patients with hs-cTnT level over 14 ng/L.Con-clusion AMI can not be excluded in chest pain patients whose hs-cTnT levels below the conventional threshold value of 14 ng/L,and these people should be dynamically monitored for 5h in emergency department.The patients can exclude AMI if the hs-cTnT levels are below 14 ng/L after 5 hours.
