Patho physiology: Cardiomyopathy refers to diseases of the heart muscle. These diseases have many causes, signs and symptoms, and treatments.In cardiomyopathy, the heart muscle becomes enlarged, thick, or rigid. In rare cases, the muscle tissue in the heart is replaced with scar tissue.As cardiomyopathy worsens, the heart becomes weaker. It's less able to pump blood through the body and maintain a normal electrical rhythm. This can lead to heart failure or irregular heartbeats called arrhythmias. In turn, heart failure can cause fluid to build up in the lungs, ankles, feet, legs, or abdomen.The weakening of the heart also can cause other complications, such as heart valve problems
Treatment: People who have cardiomyopathy but no signs or symptoms may not need treatment. Sometimes, dilated cardiomyopathy that comes on suddenly may go away on its own. For other people who have cardiomyopathy, treatment is needed. Treatment depends on the type of cardiomyopathy you have, the severity of your symptoms and complications, and your age and overall health. Treatments may include: Heart-healthy lifestyle changes, Medicines, Nonsurgical procedure, Surgery and implanted devices. The main goals of treating cardiomyopathy include: • Controlling signs and symptoms so that you can live as normally as possible • Managing any conditions that cause or contribute to the disease • Reducing complications and the risk of sudden cardiac arrest • Stopping the disease from getting worse
Research: Prevalence and Disease Outcome: because recognition of inherited disease is often limited by practice patterns which are in turn heavily influenced by the urgent demands of caring for sick patients, an important proportion of inherited disease is misdiagnosed. As an example, we discovered that nearly 25% of patients undergoing heart transplant for end stage cardiomyopathy have inherited disease, whereas current recognition of inherited disease in this population is limited to 4% of patients. This research was presented at the International Society of Heart and Lung Transplant in Prague (2012).
Statistics: In the general population, this heart muscle disease may occur in every 1 out of 500 people. 500,000. That’s the number of people in the United States that have HCM. Children under the age of 12 account for less than 10% of the total known cases of this disorder.It is estimated that up to 60% of children with HCM have a relative with the disease.In less than 10% of patients, the disease may progress to a point where the heart muscle thins and the left ventricle dilates resulting in reduced heart function. HCM is the most common cause of heart-related sudden death in people under 30 years of age. It is also the most common cause of sudden death in athletes.75% of patients with HCM do not have obstruction to the outflow of blood from the left ventricle and a loud heart murmur is therefore absent.
