Role of cardiac troponin I in the evaluation of myocardial injury.
Cardiac troponin I (cTnl) is highly specific for cardiac muscle. In this study, we compared the utility of CK and CK-MB index versus cTnl in the assessment of myocardial infarction in 155 patients being evaluated for myocardial damage. As a cardiac marker for MI, Troponin I seems to be superior to CK-MB. In the subset of patients with renal disease, cTnl has definite advantages over CK-MB. In addition, the use of cTnl has the potential to replace the measurement of lactate dehydrogenase isoenzymes.
