Quizplus · Accepted Answer

CK-MB is primarily found in the heart, but it can also be elevated in conditions involving muscle damage, such as muscular dystrophy and polymyositis, as well as after extreme physical activity. Cardiac troponin, however, is more specific to heart muscle damage and would typically remain normal in these conditions unless there is concurrent heart damage.
