CARDIAC TROPONIN-T - A SENSITIVE AND SPECIFIC NEW MARKER OF MYOCARDIAL DAMAGE IN ACUTE TRANSMURAL INFARCTION

Troponin T measurement is a relatively new diagnostic test to evaluate myocardial damage, The test was performed on sera from 52 patients, 4 2 with proven myocardial infarction (WHO criteria) and 10 control pati ents without myocardial infarction, The serum troponin T levels did no t correlate with the serum creatine kinase levels, A raised serum trop onin T level had a sensitivity of 95% and a specificity of 100% in pre dicting myocardial damage in patients with myocardial infarction. It w as also raised for a longer period than serum creatine kinase levels, making it a sensitive and specific diagnostic test in the patient who presents 72 hours after a myocardial infarction.
