Abstract: | Cardiac troponin I (cTnI) is highly specific for cardiac muscle. In this study, we compared the utility of CK and CK-MB index versus cTnI 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, cTnI has definite advantages over CK-MB. In addition, the use of cTnI has the potential to replace the measurement of lactate dehydrogenase isoenzymes. J. Clin. Lab. Anal. 12:276–279, 1998. © 1998 Wiley-Liss, Inc. |
