Myocardium and Myocarditis

What is the myocardium?

The myocardium (mi"o-KAR'de-um) is the heart's muscular wall. It contracts to pump blood out of the heart, then relaxes as the heart refills with returning blood. Its outer surface is called the epicardium (ep"ih-KAR'de-um). Its inner lining is the endocardium (en"do-KAR'de-um).

What is myocarditis?

Myocarditis (mi"o-kar-DI'tis) is inflammation of the myocardium (heart muscle).

What causes myocarditis?

Various things can cause the inflammation, including

  • a viral, bacterial or fungal infection
  • diphtheria
  • rheumatic fever
  • toxic drug poisoning
  • tuberculosis

How is myocarditis treated?

Analgesics or anti-inflammatory drugs are given to relieve pain. Antibiotics will also be prescribed if the myocarditis is due to a bacterial infection.
