When cells are damaged by disease or injury, large amounts of these leak out, causing blood tests to show that enzymes are elevated above normal. (You can roughly compare this situation to a car that's leaking oil. Leaks in many parts of the engine can have the same result: oil all over your driveway.)
CPK-2 is found in the heart. Elevated levels of CPK-2 can be the result of: 1  injury to the heart (due to accident). 2  inflammation of the heart muscle (usually from a virus). 3  electrical injuries.
