Key result
Troponin T levels did not exceed the reference range in any of the 32 stroke patients despite elevated CK-MB in 34.4%, indicating that CK-MB elevations after stroke are likely noncardiac.
Why the study?
Does CK-MB elevation after stroke indicate myocardial injury as measured by troponin T?

CK-MB elevations after stroke may not indicate myocardial injury; leaves open troponin T preference pending larger prospective studies.
Observational (n=54)
Does CK-MB elevation after stroke indicate myocardial injury as measured by troponin T?
Absolute Event Rate: 0% vs 0%
Elevated CK-MB after stroke is likely noncardiac in origin, as troponin T levels remain normal.
Ay et al. (2002) conducted an observational in Large hemispheric infarction (n=54). Large hemispheric infarction vs. Neurological diseases other than stroke was evaluated on Troponin T elevation above reference range. Troponin T levels did not exceed the reference range in any of the 32 stroke patients despite elevated CK-MB in 34.4%, indicating that CK-MB elevations after stroke are likely noncardiac.
