First enzyme to be raised in MI is
The laboratory evaluation of MI is based on measuring blood levels of macromolecules that leak out of injured myocardial cells through damaged cell membranes these molecules include myoglobin, cardiac troponins T and I (TnT, TnI), creatine kinase (CK) (specifically the myocardial isoform, CK-MB), and lactate dehydrogenase. Troponins and CK-MB have high specificity and sensitivity for myocardial damage. (Robbins Basic pathology,9th edition.pg no.382)
