Myocarditis InformationHow 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. What are symptoms of myocarditis?Myocarditis can be mild and cause virtually no noticeable symptoms. The most frequent symptom of myocarditis is pain in the chest. Other symptoms are related to the underlying triggering cause, like infection or an autoimmune disorder. The following is a list of symptoms and signs of myocarditis:
What causes myocarditis?The causative agents that damage myocardium include the following:
What is myocarditis?Myocarditis is inflammation of the heart muscle (myocardium). The inflammation of the heart muscle causes degeneration or death of heart muscle cells. Myocarditis has many different causes and can result in a range of outcomes from mild (presenting briefly and resolving) to rapidly progressing fatal disease. Myocarditis is differentiated from pericarditis because pericarditis is inflammation of the sac that surrounds the heart and does not involve heart muscle like myocarditis. However, it is not unusual to have a patient present with both pericarditis and myocarditis.There are many different types of myocarditis and a wide range of possible agents that can trigger the disease. Examples include:
What is the prognosis (outlook) for patients with myocarditis?The prognosis for patients with acute myocarditis who rapidly recover is very good. Even patients that develop severe myocarditis can completely recover with mild or no complications. However, if damage to the heart muscle becomes chronic and/or progressive, the prognosis for the patient declines. Those who develop severely weakened heart muscle cardiomyopathy have a poorer prognosis. What is the treatment for myocarditis?Often, myocarditis improves on its own without treatment with complete recovery. Sometimes, treatment of the underlying cause (such as bacterial infections) can lead to complete recovery (for example, after antibiotics). Consequently, the diagnosis of the precise underlying cause of myocarditis can help in the optimal choice of treatment. However, in patients with more prolonged or more severe cases of myocarditis, individuals may need more specific medications or even hospitalization. Medications to reduce the heart's workload and/or reduce edema are commonly used to treat symptoms of myocarditis. They may include the following:
