Viral myocarditis

Viral Myocarditis

Viral myocarditis (pronunciation: vahy-ruhl my-oh-kahr-dahy-tis) is a disease characterized by inflammation of the heart muscle (myocardium) due to a viral infection.

Etymology

The term "viral myocarditis" is derived from three words: "virus", a type of infectious agent; "myo", a prefix from the Greek "myos" meaning muscle; and "carditis", from the Greek "kardia" meaning heart. Thus, viral myocarditis refers to inflammation of the heart muscle caused by a virus.

Definition

Viral myocarditis is a condition where the myocardium is inflamed due to a viral infection. This inflammation can lead to weakened heart contractions and irregular heart rhythms, resulting in a variety of symptoms including shortness of breath, chest pain, fatigue, and rapid or irregular heartbeats.

Causes

Viral myocarditis is most commonly caused by enteroviruses such as Coxsackievirus. However, it can also be caused by other viruses such as Influenza virus, Hepatitis C virus, and Human Immunodeficiency Virus (HIV).

Symptoms

Symptoms of viral myocarditis can vary greatly from person to person. They may include fatigue, shortness of breath, rapid or irregular heartbeats, chest pain, and swelling in the legs, ankles, and feet.

Diagnosis

Diagnosis of viral myocarditis typically involves a combination of medical history, physical examination, and diagnostic tests such as blood tests, Electrocardiogram (ECG), Echocardiogram, and sometimes a Cardiac MRI or Endomyocardial biopsy.

Treatment

Treatment for viral myocarditis primarily involves managing symptoms and supporting heart function. This may include medications to reduce inflammation and control heart rhythm, as well as lifestyle changes such as rest and a low-sodium diet. In severe cases, hospitalization may be required.
