Single-Point Troponin T Measurement On The Day Of Coronary Care Unit Discharge After Myocardial Infarction Strongly Correlates With Ejection Fraction And Infarct Size By Nuclear Imaging And With CK-MB Release

The extent of injury to the myocardium after infarction - one of the most influential factors in the prognosis — has previously been assessed by CK-MB release curves using serial serum sampling(l). Aim of the present study was to investigate the ability of a single-point measurement of circulating cardiac troponin T (cTnT) concentrations, performed on day of discharge from coronary care unit (CCU), to estimate the infarct size and assess left ventricular (LV) function in patients with acute myocardial infarction (AMI).
