Myocardial degeneration is another term for cardiomyopathy, which refers to a disease of heart muscle that enlarges the muscle and makes it rigid, according to Mayo Clinic. This disease makes it harder for the heart to pump blood through the body.
Cardiomyopathy varies greatly in terms of severity among patients. In mild cases, affected individuals are hardly aware of it. In severe cases, the accompanying symptoms and complications include irregular heartbeat, heart failure, formation of scar tissue, inflammation of the lining of the heart, and the buildup of fluid in the lungs or legs. Heart failure due to severe cardiomyopathy is possible, reports Mayo Clinic.
Hypertension, heart attack and infection all potentially cause this condition. Treatments include lifestyle changes, medication and device implantation. Heart transplant surgery is recommended in extreme cases. The severity of the cardiomyopathy determines the necessary course of treatment.
