for cardiac cell damage
used for initial injury
What is CKMB - CORRECT-ANSWERS*****CK isoenzyme specific to cardiac muscle tissue
(MI)

Differential for chest pain - CORRECT-ANSWERS*****Consider:
Myocardium- angina, MI, myocarditis, heart failure
Pericardium- pericarditis
Aorta- dissecting aortic aneurysm
Trachea and bronchi- bronchitis
