Cardiomyopathy is a disease of the heart muscle. It causes the heart to have a more challenging time pumping blood to the rest of the body, which can lead to symptoms of heart failure. Cardiomyopathy also can lead to some other severe heart conditions. There are various types of cardiomyopathy, including dilated, hypertrophic, and restrictive cardiomyopathy. Treatment includes medicines, sometimes surgically implanted devices, and heart surgery. Some people with severe cardiomyopathy need a heart transplant. Treatment depends on the type of cardiomyopathy and its severity. Prof. Dr. Emmelien Van Craenenbrouck (University Hospital Antwerp) ezxplains.
