Hypertrophic cardiomyopathy is thought to be the most common inherited or genetic heart disease. While this type of cardiomyopathy occurs at many ages, in children and young adults with this condition there may be no symptoms, yet they are at high risk of sudden cardiac death.
What are the three types of cardiomyopathy?
The main types of cardiomyopathy are: Dilated cardiomyopathy. Hypertrophic cardiomyopathy. Restrictive cardiomyopathy.
Which type of cardiomyopathy is the most common cardiomyopathy in the United States?
Dilated cardiomyopathy (DCM) is the most common type, occurring mostly in adults younger than 50. It affects the heart's ventricles and atria, the lower and upper chambers of the heart.
What is the least common form of cardiomyopathy?
Restrictive cardiomyopathy occurs when the heart muscle becomes stiff and not able to fill with blood properly. It's the least common type of cardiomyopathy in the U.S. It often occurs due to an underlying problem, such as amyloidosis, hemochromatosis, scleroderma, or sarcoidosis.
What is the difference between HCM and DCM?
In the case of dilated cardiomyopathy the heart can't pump blood as well as a healthy heart can, since the ventricle stretches and thins (dilates), where in the case of hypertrophic cardiomyopathy the ventricular septum gets thicker.
