In viral myocarditis, how are cardiac enzymes typically described?

Explanation:
Cardiac enzymes reflect damage to heart muscle. In viral myocarditis, the injury is primarily inflammatory with less extensive necrosis than in a heart attack. This means only a small amount of enzyme leaks into the blood, so elevations are typically mild. Troponin and other enzymes can be modestly raised or even normal, whereas large rises are more characteristic of extensive ischemic injury or severe myocarditis. So the usual description is a mild elevation.
