Inflammatory heart diseases is inflammation of a part of the heart, often due to infection. Inflammation of the outer surface of the heart (pericardium) is called pericarditis. Inflammation of the muscle of the heart (myocardium) is called myocarditis. Inflammation of the inner lining of the heart (endocardium) is called endocarditis.
Pericarditis causes chest pain and breathlessness. The commonest cause is a viral infection. Tuberculosis U002 Map 373 can also cause it.
Myocarditis causes breathlessness and a throbbing heart (palpitations). There may also be symptoms from other aspects of the infection that caused the myocarditis. A wide variety of viral and bacterial infections occassionally cause it, including Diphtheria U014 Map 383. Parasites can cause it, especially Chagas' disease U023 Map 392. Chronic alcoholism U086 Map 443, and Rheumatic fever U105 Map 452, can also be causes.
Endocarditis usually involves bacterial infection on the surface of the heart valves. Untreated it is usually fatal, leading to heart failure, and/or Strokes U109 Map 456 (from debris breaking off (emboli) into the blood stream which then can block the arteries in the brain).
Inflammatory heart diseases caused 0.71% of all deaths worldwide in 2002, an average of 65 deaths per million people per year.
