Restrictive cardiomyopathy, the rarest form of cardiomyopathy, is a condition in which the walls of the lower chambers of the heart (the ventricles) are abnormally rigid and lack the flexibility to expand as the ventricles fill with blood.
The pumping or systolic function of the ventricle may be normal but the diastolic function (the ability of the heart to fill with blood) is abnormal. Therefore, it is harder for the ventricles to fill with blood, and with time, the heart loses the ability to pump blood properly, leading to heart failure.
Angina -- Discomfort, pain, or pressure in the chest caused by an inadequate blood supply to the heart. Pain may also be felt in the neck, jaw, or arms.
Angiogram (cardiac catheterization) -- A test used to diagnose heart disease. During the procedure a catheter is inserted into an artery, usually in the leg, and contrast dye is injected into the arteries and heart. X-rays of the arteries and heart are taken.
Anticoagulant -- A medication that prevents blood from clotting; used for...
The size of the heart may remain normal with restrictive cardiomyopathy. In some cases, restrictive cardiomyopathy may be confused with constrictive pericarditis, a condition in which the layers of the pericardium (the sac that surrounds the heart) become thickened, calcified, and stiff.
A myocardial biopsy, or biopsy of the heart muscle, occasionally is done to determine the cause of cardiomyopathy. During a myocardial biopsy, a small tissue sample is taken from the heart and examined under a microscope to examine the cause of the symptoms.
What Is the Treatment for Restrictive Cardiomyopathy?
Treatment of restrictive cardiomyopathy is difficult. Treatment is usually focused on treating the cause of this condition. Doctors recommend lifestyle changes and medications to treat heart failure.
What Lifestyle Changes Are Recommended for Restrictive Cardiomyopathy?
Lifestyle changes can help restrictive cardiomyopathy. They might include:
