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. It often occurs due to an underlying problem such as amyloidosis, hemochromatosis, scleroderma, or sarcoidosis.
Restrictive cardiomyopathy does not appear to be inherited, but some of the diseases that lead to the condition are inherited. Symptoms may include fatigue, swelling of the arms and legs, and trouble breathing on exertion. ARVC is a rare type of cardiomyopathy that occurs if the muscle tissue in the right ventricle dies and is replaced by fat or scar tissue:. This process disrupts the heart's electrical system, causing arrhythmias.
Symptoms include heart palpitations and fainting after physical activity. It can cause sudden cardiac arrest in young athletes. Search Encyclopedia. Cardiomyopathy What is cardiomyopathy? There are many causes of cardiomyopathy, including: Alcohol abuse High blood pressure Coronary artery disease Viral infections Muscle disorders such as muscular dystrophy Certain medicines Illegal drugs such as cocaine or methamphetamine Often, the exact cause of the muscle disease is never found.
How does cardiomyopathy differ from other heart disorders? Cardiomyopathy differs from many of the other disorders of the heart in several ways, including: Cardiomyopathy can occur in young people.
The condition tends to be progressive. Call your doctor if you notice new or worsening symptoms, such as swelling in your ankles, feet, legs, abdomen, or veins in the neck.
These symptoms may be a sign that the disease is getting worse. Cardiomyopathy often runs in families. Your doctor may suggest that your parents, brothers and sisters, and children get checked to see whether they have the disease.

Overview The types of cardiomyopathy are: Hypertrophic cardiomyopathy Dilated cardiomyopathy Restrictive cardiomyopathy Arrhythmogenic right ventricular dysplasia Unclassified cardiomyopathy Cardiomyopathy can be acquired or inherited. Outlook Some people who have cardiomyopathy have no signs or symptoms and need no treatment.
Types - Cardiomyopathy. Hypertrophic Cardiomyopathy Hypertrophic cardiomyopathy is very common and can affect people of any age. Dilated Cardiomyopathy Dilated cardiomyopathy develops when the ventricles enlarge and weaken. Restrictive Cardiomyopathy Restrictive cardiomyopathy develops when the ventricles become stiff and rigid but the walls of the heart do not thicken.
Arrhythmogenic Right Ventricular Dysplasia Arrhythmogenic right ventricular dysplasia is a rare type of cardiomyopathy that occurs when the muscle tissue in the right ventricle is replaced with fatty or fibrous tissue. Unclassified Cardiomyopathy Other types of cardiomyopathy are grouped into this category and can include: Left ventricular noncompaction happens when the left ventricle has trabeculations, projections of muscle inside the ventricle. Takotsubo cardiomyopathy, or broken heart syndrome, happens when extreme stress leads to heart muscle failure.
Though rare, this condition is more common in post-menopausal women. Other Names - Cardiomyopathy. Other Names for Dilated Cardiomyopathy Alcoholic cardiomyopathy. This term is used when overuse of alcohol causes the disease. Congestive cardiomyopathy. Diabetic cardiomyopathy. Familial dilated cardiomyopathy. Idiopathic cardiomyopathy. Ischemic cardiomyopathy. This term is used when ischemic heart disease also called coronary artery disease or heart attack causes the disease.
Peripartum cardiomyopathy. This term is used when the disease develops in a woman shortly before or after she gives birth. Primary cardiomyopathy. Other Names for Hypertrophic Cardiomyopathy Asymmetric septal hypertrophy Familial hypertrophic cardiomyopathy Hypertrophic nonobstructive cardiomyopathy Hypertrophic obstructive cardiomyopathy Idiopathic hypertrophic subaortic stenosis Other Names for Restrictive Cardiomyopathy Idiopathic restrictive cardiomyopathy Infiltrative cardiomyopathy Other Names for Arrhythmogenic Right Ventricular Dysplasia Arrhythmogenic right ventricular cardiomyopathy Right ventricular cardiomyopathy Right ventricular dysplasia.
Causes - Cardiomyopathy. Hypertrophic Cardiomyopathy Hypertrophic cardiomyopathy usually is inherited. The extra iron is toxic to the body and can damage the organs, including the heart. Sarcoidosis : A disease that causes inflammation and can affect various organs in the body. Researchers believe that an abnormal immune response may cause sarcoidosis.
Some cancer treatments, such as radiation and chemotherapy Arrhythmogenic Right Ventricular Dysplasia Researchers think that arrhythmogenic right ventricular dysplasia is an inherited disease. Risk Factors - Cardiomyopathy. Major Risk Factors Certain diseases, conditions, or factors can raise your risk for cardiomyopathy.
Major risk factors include: A family history of cardiomyopathy, heart failure , or sudden cardiac arrest SCA A disease or condition that can lead to cardiomyopathy, such as ischemic heart disease , heart attack , or a viral infection that inflames the heart muscle Diabetes or other metabolic diseases, or severe obesity Diseases that can damage the heart, such as hemochromatosis , sarcoidosis , or amyloidosis Long-term alcoholism Long-term high blood pressure Some people who have cardiomyopathy never have signs or symptoms.
Screening and Prevention - Cardiomyopathy. Your doctor may advise you to make heart-healthy lifestyle changes , such as: Avoiding the use of alcohol and illegal drugs Getting enough sleep and rest Heart-healthy eating Physical activity Quitting smoking Managing stress Your cardiomyopathy may be due to an underlying disease or condition.
Get regular checkups with your doctor. Take all of your medicines as your doctor prescribes. Signs, Symptoms, and Complications - Cardiomyopathy. These signs and symptoms include: Shortness of breath or trouble breathing, especially with physical exertion Fatigue tiredness Swelling in the ankles, feet, legs, abdomen, and veins in the neck Other signs and symptoms may include dizziness; light-headedness; fainting during physical activity; arrhythmias irregular heartbeats ; chest pain, especially after physical exertion or heavy meals; and heart murmurs.
Diagnosis - Cardiomyopathy. Specialists Involved Often, a cardiologist or pediatric cardiologist diagnoses and treats cardiomyopathy. Medical and Family Histories Your doctor will want to learn about your medical history. Physical Exam Your doctor will use a stethoscope to listen to your heart and lungs for sounds that may suggest cardiomyopathy. Diagnostic Tests Your doctor may recommend one or more of the following tests to diagnose cardiomyopathy.
Blood Tests During a blood test , a small amount of blood is taken from your body. Blood tests give your doctor information about your heart and help rule out other conditions. Chest X Ray A chest x ray takes pictures of the organs and structures inside your chest, such as your heart, lungs, and blood vessels.
Holter and Event Monitors Holter and event monitors are small, portable devices. Echocardiography Echocardiography echo is a test that uses sound waves to create a moving picture of your heart. Stress Test Some heart problems are easier to diagnose when your heart is working hard and beating fast. Diagnostic Procedures You may have one or more medical procedures to confirm a diagnosis or to prepare for surgery if surgery is planned. Cardiac Catheterization This procedure checks the pressure and blood flow in your heart's chambers.
Coronary Angiography This procedure often is done with cardiac catheterization. Myocardial Biopsy For this procedure, your doctor removes a piece of your heart muscle. Myocardial biopsy is useful for diagnosing some types of cardiomyopathy. Genetic Testing Some types of cardiomyopathy run in families.
Treatment - Cardiomyopathy. Your doctor may prescribe medicines to: Balance electrolytes in your body. Electrolytes are minerals that help maintain fluid levels and acid-base balance in the body. They also help muscle and nerve tissues work properly. Abnormal electrolyte levels may be a sign of dehydration lack of fluid in your body , heart failure , high blood pressure, or other disorders. Aldosterone blockers are an example of a medicine used to balance electrolytes.
