What is the most common infectious cause of cardiomyopathy?

Parvovirus B19 is the most common cause of viral cardiomyopathy, both in the presence or without inflammation.

Can a viral infection cause heart failure?

An rare type of heart failure known as viral cardiomyopathy is triggered by a viral infection. Most people with heart failure can trace it to long-standing cardiac risks.

Which one is currently the most common virus to cause myocarditis?

The most common form of viral myocarditis is lymphocytic myocarditis in which the inflammatory infiltrate comprises predominantly mononuclear cells, including lymphocytes, macrophages, dendritic cells, and natural killer (NK) cells.

Is viral cardiomyopathy fatal?

It can cause the flu or attack the heart, creating an infection that lasts from 2 to 10 days. Cardiac symptoms can potentially occur within two weeks. Symptoms may include fever, fatigue, and chest pains. It doesn’t usually cause death, but it may result in permanent heart damage, particularly if it recurs.

How is viral cardiomyopathy treated?

Medications to treat myocarditis may include: Corticosteroids. These medicines suppress the immune system. They may be used to treat some rare types of viral myocarditis, such as giant cell and eosinophilic myocarditis.

Is viral cardiomyopathy treatable?

The subacute phase of myocarditis (phase 2) can last weeks to several months and, in most patients, the immune response and ventricular contractile function improve as viral titres decrease. However, in some patients, the cardiomyopathy enters a chronic and irreversible phase.

How long does it take to recover from viral cardiomyopathy?

Cardiologists typically recommend a resting period of three to six months after viral myocarditis to allow the heart tissue to heal without intense physical exercise.

Is viral myocarditis curable?

There is no cure at present for either type of myocarditis. Physicians treat the disease’s symptoms, which can include tachycardia, arrhythmias and heart failure. In some cases, however, an autoimmune disorder may be treated alongside cardiac symptoms to support recovery.

What is the mortality rate of myocarditis?

Immediate complications of myocarditis include ventricular dysrhythmias, left ventricular aneurysm, CHF, and dilated cardiomyopathy. The mortality rate is up to 20% at 1 year and 50% at 5 years. Despite optimal medical management, overall mortality has not changed in the last 30 years.
