![]() In rare instances, vaccines may also cause allergic responses that lead to myocarditis. Examples include antibiotics, such as penicillin, and seizure drugs, such as phenytoin. ![]() Various medications produce side effects that can cause pericarditis, myocarditis, or both. They can cause changes in the heart valves that lead to endocarditis.

A parasite infection leading to Chagas disease: It is a serious condition in Latin America that can lead to myocarditis as one of its complications.They occur more often in people with illnesses that suppress immunity, such as HIV. Fungal infections: These can cause endocarditis, and they are also rare causes of pericarditis and myocarditis.These happen when blood cells and bacteria form clumps, which build up on the heart valves. Bacterial infections: Bacterial infections are the most common cause of endocarditis.These infections can also cause a chronic, or ongoing, response. They can produce an acute response, which is one that is sudden and intense. Viral infections: These are the most common cause of pericarditis and myocarditis.The following are the types of infection that may cause an inflamed heart: Pericarditis can disrupt the heart’s function and rhythm.Ĭauses of an inflamed heart include infections, autoimmune diseases, medications, and environmental factors.

The condition can affect small or large parts of the heart, which can hinder its ability to pump blood. ![]() Myocarditis involves inflammation and other changes in the heart muscle cells. The buildup on the inner lining can cause valve issues, such as leaking. In addition, pieces of the clumps may break off and end up in other parts of the body, where they can obstruct blood flow. In this condition, clumps of blood cells and fungi or bacteria build up on the inner lining. While it is rare, it is life threatening.
