Myocarditis. Myocarditis occurs when a virus (or, more rarely, a bacteria or fungus) infects the body, causing an inflammation of the heart muscle. Myocarditis can also be caused by an adverse reaction to certain medicines, such as chemotherapy drugs, and exposure to some chemicals. Learn more about Myocarditis.
The myocardium is the muscle of the heart. This muscle is supplied by arteries that branch off the aorta. So everytime the heart beats it pushes blood into the aorta and thus â¦ into systemic circulation and thus into the heart wall, as well. These arteries that supply the myocardium are called coronary arteries.
