Objectives Evaluation of patients with acute chest pain when they admitted is time-consuming. We prospectively investigated the role of bedside troponin T test for predicting the risk of death and acute heart failure of patients with acute chest pain. Methods and Results 502 consecutive patients with chest pain for less than 24 hours were determined by troponin T test at bedside and quantitative troponin I test in lab. For bedside troponin T tests, there were 160 patients in positive and 323 in negative. During 30 days of followed-up. Myocardial infarction evolved in 139 patients among 160 patients in positive troponin T test, only 7 patients in negative one. Acute heart failure occurred in 51 patients among the positive group, but 37 occurred it at negative group.The odds ratio of acute heart failure of positive group vs.negative group was 3.6. Patients died 39 in positive group, 15 in negative group, the all-cause death odds ratio of positive group vs. negative group was 6.7; 31patients died with cardiac event in positive group, 5 in negative group only. Conclusions Bedside Troponin T test is a powerful and independent predictor of death and acute heart failure for patients with acute chest pain.
