Myocarditis

Myocarditis, also known as inflammatory cardiomyopathy, is a disease in which inflammation of the heart muscle causes impaired cardiac contraction and relaxation. Infectious factors such as viruses, bacteria, rickettsiae, and parasites are the main causes of myocarditis. Certain physicochemical factors and autoimmune diseases can also lead to myocarditis. Viral myocarditis is relatively common. It can occur in people of all ages, from infants to the elderly. It is more common in children and young adults under 40, with a slightly higher incidence in males than in females. This disease is highly dangerous, and severe cases can manifest as fulminant myocarditis, which can lead to sudden death.
