The diagnosis of myocarditis is often difficult. There is no specific test for it. Many other causes of heart problems must be ruled out. To do this, your doctor will ask about your symptoms and medical history, and perform a physical exam.
Tests may include the following:
—a test that records the heart’s activity by measuring electrical currents through the heart muscle.
—a test that uses radiation to take pictures of structures inside the body.
Cardiac enzyme blood test—in some cases certain enzymes are elevated.
—a test that uses high-frequency sound waves (ultrasound) to examine the size, shape, and motion of the heart.
—removal of a sample of heart tissue to test for infection.
Cardiovascular magnetic resonance—the use of magnetic waves to take pictures of structures inside the body.
The universally recommended therapy for myocarditis is bedrest, no physical activity, and supplemental oxygen. Corticosteroids may be given to help inflammation. You will most likely be admitted to a hospital.
Specific treatment is directed at the underlying cause if possible. For instance:
If the cause is a bacterial infection, antibiotics are prescribed.
If it is viral, antiviral agents will be prescribed.
Immunosuppressive therapy may be used if myocarditis is due to an autoimmune disorder such as lupus or scleroderma.
If heart failure symptoms are present, medications are given to support the function of the heart. These include diuretics, ACE-inhibitors, beta-blockers, and antiarrhythmic agents.
Additionally, a defibrillator, which helps maintain the normal rhythm of the heart, may be implanted into your chest. Severe cases may require a cardiac transplant.
Myocarditis is hard to prevent. To help reduce your chances of getting myocarditis, reduce your exposure to identified causes. Some examples include:
Practice good hygiene to avoid the spread of infection. For example, wash your hands regularly.
Always use latex condoms during sexual activity.
Have sex with only one partner, who has sex only with you.
