Question

About myocardial infarction and its biomarkers, all of the following are correct EXCEPT: a. Depending on the duration of Troponin elevation the diagnosis of MI can be confirmed at early and late stages of the attack b. Myoglobin release from ischemic cardiac muscle occurs earlier than the release of CK c. Electrocardiogram shows inversion of T wave, ST elevation, and pronounced Q wave d. In cardiac muscle, the only creatine kinase (CK) isoenzyme is CK2-MB type.
