What is restrictive cardiomyopathy?
Restrictive cardiomyopathy is a form of cardiomyopathy in which the walls of the heart become rigid.
Can restrictive cardiomyopathy be prevented?
Obtaining early treatment for diseases that might cause restrictive cardiomyopathy might prevent or slow the development of heart wall stiffness.
What is the prognosis for restrictive cardiomyopathy?
The heart muscle of the ventricles becomes rigid
What is the prognosis for cardiomyopathy?
The prognosis for patients with restrictive cardiomyopathy is poor. If the disease process causing the problem can be treated, the damage to the heart muscle may be stopped.
How is restrictive cardiomyopathy diagnosed?
The diagnosis is usually based on a physical examination, echocardiography, and other tests as needed.
What are some symptoms of dilated cardiomyopathy?
Dilated cardiomyopathy means that the heart is not pumping blood as it should be, resulting in symptoms such as fatigue and weakness, shortness of breath and swelling of the abdomen.
What are the symptoms of cardiomyopathy?
Cardiomyopathy is a disease that causes the heart to become enlarged and weakened. Some of the symptoms of cardiomyopathy include swelling on the ankle and feet, fatigue, dizziness, and trouble breathing.
Restrictive cardiomyopathy?
DefinitionRestrictive cardiomyopathy refers to a group of disorders in which the heart chambers are unable to properly fill with blood because of stiffness in the heart.Alternative NamesCardiomyopathy - restrictive; Infiltrative cardiomyopathyCauses, incidence, and risk factorsIn restrictive cardiomyopathy, the heart is of normal size or only slightly enlarged. However, it cannot relax normally during the time between heartbeats when the blood returns from the body to the heart (diastole).Later in the disease, the heart may not pump blood efficiently. The abnormal heart function can affect the lungs, liver, and other body systems. Restrictive cardiomyopathy may affect either or both ventricles. It may be associated with a disease of the heart muscle.The most common causes of restrictive cardiomyopathy are amyloidosis and scarring of the heart from an unknown cause (idiopathic myocardial fibrosis). It frequently occurs after a heart transplant.Other causes of restrictive cardiomyopathy include:Carcinoid heart diseaseDiseases of the heart lining (endocardium), such as endomyocardial fibrosis and Loeffler's syndrome (rare)Iron overload (hemochromatosis)Radiation fibrosisSarcoidosisSclerodermaTumors of the heartSymptomsSymptoms of heart failure are most common. Usually, these symptoms develop slowly over time. However, sometimes symptoms start very suddenly and are severe.Common symptoms are:CoughDifficulty breathingAt nightEspecially with exertionWhen lying flatFatigue, poor exercise toleranceIrregular or rapid pulseLoss of appetiteSwelling of the abdomenSwelling of the feet and anklesOther symptoms may include:Chest painDecreased alertness or concentrationFailure to thrive (in children)Low urine productionNeed to urinate at night (in adults)Shock (low blood pressure)Signs and testsAn examination may show:Enlarged (distended) or bulging neck veinsEnlarged liverLung crackles and abnormal or distant heart sounds when listening to the chest with a stethoscope (auscultation)Fluid backup into the hands and feetSigns of heart failureChildren will have:Difficulty feedingPale skinPoor growthWeak pulses in the legs and armsTests for restrictive cardiomyopathy include:Cardiac catheterization and coronary angiographyChest CT scanChest x-rayECG(electrocardiogram)Echocardiogramand Doppler studyMRI of the heartNuclear heart scan (MUGA, RNV)Serum iron studiesRestrictive cardiomyopathy may be hard to tell apart from constrictive pericarditis. A biopsy of the heart muscle or cardiac catheterization may help confirm the diagnosis.TreatmentWhen the cause of any cardiomyopathy can be found, that condition is treated.Few treatments are known to be effective for restrictive cardiomyopathy. The main goal of treatment is to control symptoms and improve quality of life.The following treatments may be used to control symptoms or prevent problems:Blood thinning medications, either aspirin or warfarinChemotherapy (in some situations)Diuretics to remove fluid and help improve breathingMedications to prevent or control irregular or abnormal heart rhythmsSteroids for specific causesA heart transplant may be considered if the heart function is very poor and the patient has many symptoms.Expectations (prognosis)People with restrictive cardiomyopathy may be heart transplant candidates. The outlook depends on the cause of the condition, but it is usually poor. Average survival after diagnosis is 9 years.ComplicationsArrhythmiasMitral regurgitationProgressive heart failureTricuspid regurgitationCalling your health care providerCall your health care provider if you have symptoms of restrictive cardiomyopathy.ReferencesHare JM.

glycogen cardiomyopathy
What is cardiomyopathy and what are its symptoms?
Cardiomyopathy is a condition of the heart. With this condition the heart muscle is diseased and cannot function properly. With this condition oxygenated blood cannot be pumped adequately and therefore causes an inability to deliver oxygenated blood to bodily tissues.
What is the most common form of cardiomyopathy?
Congestive cardiomyopathy
What is prim cardiomyopathy nec?
Primary cardiomyopathy not elsewhere classified
