The patient was admitted with chest pain to rule out a myocardial infarction (MI). Which cardiac enzyme test is most indicative of an MI?
a. Troponin
b. Myoglobin
c. CPK
d. CK-MB
A
Elevated troponin levels are most indicative of an MI as these enzymes are specific to heart mus-cle damage. Elevated troponin, along with elevated CK-MB are the best diagnostic lab values when determining if an MI has occurred. CPK rises with injury to other muscles as well as car-diac muscle. Myoglobin levels rise with cardiac damage but are as indicative as other enzymes.
