Viral myocarditis - causes, Lake Louise criteria, clinical features, investigations, treatment
Myocarditis is inflammation of the heart muscle, called the myocardium. The condition can reduce the heart's ability to pump blood. Myocarditis can cause chest pain, shortness of breath, and rapid or irregular heartbeats.
Infection with a virus is one cause of myocarditis. Sometimes myocarditis is caused by a medicine reaction or a condition that causes inflammation throughout the body.
Severe myocarditis weakens the heart so that the rest of the body doesn't get enough blood. Clots can form in the heart, leading to a stroke or heart attack.
Treatment for myocarditis may include medicines, procedures or surgeries.
