The combination of a continuous 12-lead ECG and troponin T; a valuable tool for risk stratification during the first 6 hours in patients with chest pain and a non-diagnostic ECG.
AIMS: The aim was to examine the early prognostic value of a combination of a continuous 12-lead ECG and troponin T in patients with chest pain and an ECG non-diagnostic for acute myocardial infarction. METHODS AND RESULTS: ST monitoring was performed and samples for analysis of troponin T were collected from admission for 12 h from 598 patients. After 6 h, the peak value of troponin T in 27% was > or = 0.10 microg.l(- 1), while 15% had had ST episodes, defined as transient ST deviations of at least 0.1 mV. Both a troponin T > or = 0.10 microg. l(-1) and ST episodes predicted worsening outcome. After 30 days, there were 6.8% and 1.4% (P or = 0.10 microg.l(-1), respectively. The corresponding event rates in patients with and without ST episodes were 10% and 1.6% (P
