  Lifespan's A - Z Health Information Library - Restrictive cardiomyopathy   (Site not responding. Last check: 2007-11-01)
Restrictive cardiomyopathy refers to a group of disorders in which the heart chambers are unable to fill with blood properly because of stiffness of the heart.
In restrictive cardiomyopathy, the heart is normal in size or only slightly enlarged, but it cannot relax normally during diastole (that is, the time between heartbeats in which the blood returns from the body to the heart).
Restrictive cardiomyopathy may affect either or both ventricles and may or may not be associated with a disease of the heart muscle.

 Cardiomyopathy - Wikipedia, the free encyclopedia
Cardiomyopathy, which literally means "heart muscle disease", is the deterioration of the function of the myocardium (i.e., the actual heart muscle) for any reason.
Cardiomyopathy of any cause typically leads to signs and symptoms of heart failure as the pumping efficiency of the heart is diminished.
Ischemic cardiomyopathy is a weakness in the muscle of the heart due to inadequate oxygen delivery to the myocardium with coronary artery disease being the most common cause.

 Heart Disease and Restrictive Cardiomyopathy
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.
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.
Restrictive cardiomyopathy is diagnosed based on medical history (your symptoms and family history), physical exam, and tests: such as blood tests, electrocardiogram, chest X-ray, echocardiogram, exercise stress test, cardiac catheterization, CT scan, MRI and radionuclide studies (Multigated Acquisition Scan).

 Restrictive Cardiomyopathy - SJMMC, Ann Arbor, Michigan MI
Sometimes restrictive cardiomyopathy can be mistaken for constrictive pericarditis (inflammation of the sac that surrounds the heart) or hypertrophic cardiomyopathy (in which the heart muscle is thicker than usual).
In most cases, restrictive cardiomyopathy is a progressive disease in which the underlying cause of the disease is not known (idiopathic restrictive cardiomyopathy) and, therefore, cannot be directly treated.
People with restrictive cardiomyopathy, especially those with atrial fibrillation, are at risk for developing clots, which can travel through the bloodstream to other places in the body and cause a heart attack, pulmonary embolism, or stroke.

 Restrictive Cardiomyopathy
Restrictive cardiomyopathy is rare in the United States and most other industrial nations.
In the United States, restrictive cardiomyopathy is most commonly related to the following: amyloidosis, in which abnormal protein fibers (amyloid) accumulate in the heart's muscle; sarcoidosis, an inflammatory disease that causes the formation of small lumps in organs; and hemochromatosis, an iron overload of the body, usually due to a genetic disease.
In general, restrictive cardiomyopathy does not appear to be inherited; however, some of the diseases that lead to the condition are genetically transmitted.

Abstract: A restrictive hemodynamic profile with left ventricular (LV) end-diastolic volume < 100 ml/m2 and LV end-diastolic: pressure > 18 mm Hg, in the absence of endomyocardial, pericardial, and specific cardiomyopathy, is a peculiar: feature of primary restrictive cardiomyopathy.
Abstract: The differentiation of restrictive cardiomyopathy from pericardial constriction remains a difficult clinical problem.: Although the historical, noninvasive, and hemodynamic and angiographic features discussed here provide poor: discriminating value when considered individually, a combination of clues may suggest one diagnosis or the other.: Endomyocardial biopsy affords the greatest hope of avoiding unnecessary surgical exploration.
