How is myocarditis diagnosed?
Myocarditis is preliminarily diagnosed by detecting signs of irritation of heart muscle during the patient's history and physical exam. Blood tests for heart muscle enzymes (CPK levels) can be elevated. Electrical testing (EKG) can suggest irritation of heart muscle and document irregular beating of the heart. Nuclear heart scan testing can show irregular areas of heart muscle. Other tests to help definitively diagnose myocarditis include chest X-rays to determine the size and shape of the heart, MRI, and echocardiogram. Sometimes cardiac catheterization with heart muscle biopsy (endomyocardial biopsy) may be done to definitively determine the likely underlying cause for the disease.
