Prevention and Treatment of Cardiomyopathy
People who have cardiomyopathy, but no signs or symptoms, may not need treatment. Sometimes, dilated cardiomyopathy that comes on suddenly may go away on its own.
In other instances, treatment is needed. Treatment hinges on a few factors:
- Type of cardiomyopathy
- Severity of your symptoms and complications
- Age
- Overall health.
Treatment goals
When treating cardiomyopathy, objectives include:
- Stopping the disease from getting worse
- Managing any conditions that cause or contribute to the cardiomyopathy
- Reducing complications and the risk of sudden cardiac arrest (SCA)
- Controlling symptoms so that you can live as normally as possible
Treatments for cardiomyopathies
Treatment for cardiomyopathy may include one or more of the following:Lifestyle changes
Lifestyle changes may help manage a condition that’s causing your cardiomyopathy.
Healthy diet and physical activity
-
A healthy diet is part of a healthy lifestyle.
- A healthy diet includes a variety of and grains. Half of your grains should come from whole-grain products.
- Choose foods that are low in saturated and trans fats. Healthy choices include lean meats, poultry without skin, fish, beans as well as fat-free or low-fat milk and milk products.
- Choose and prepare foods with little salt (sodium). Too much sodium can raise your risk of high blood pressure. Studies show that following a Dietary Approaches to Stop Hypertension (DASH) eating plan can lower blood pressure.
- Choose foods and beverages that are low in added sugar.
- Avoid drinking alcohol. If you drink alcoholic beverages, do so in moderation.
- Aim for a healthy weight by staying within your daily calorie needs. Balance the calories you take in with the calories you use during physical activity. Being overweight and obese can make your heart work harder.
- Quit smoking
- Manage stress
- Treat underlying conditions, such as diabetes and high blood pressure
- Be as physically active as you can, but talk to your health care professional before increasing your physical activity if you:
- Take medications.
- Have an ongoing health problem.
- Experience symptoms such as chest pain, shortness of breath or dizziness.
Medications
Many medications are used to treat cardiomyopathy. Depending on the type of cardiomyopathy, your health care professional may prescribe medicines to:
- Lower your blood pressure.
- Slow your heart rate.
- Keep your heart beating with a normal rhythm.
- Balance electrolytes in your body.
- Remove excess fluid and sodium from your body.
- Prevent blood clots from forming.
- Reduce inflammation.
Procedures for cardiomyopathy
A range of surgical and nonsurgical procedures can be used to treat cardiomyopathy:
- Septal myectomy: This open-heart surgery is considered for people who have obstructive hypertrophic cardiomyopathy and severe symptoms. A surgeon removes part of the thickened septum that’s bulging into the left ventricle. This improves blood flow within the heart and out to the body.
- Alcohol septal ablation (nonsurgical procedure): Ethanol (a type of alcohol) is injected through a tube into the small artery that supplies blood to the area of heart muscle thickened by hypertrophic cardiomyopathy. The alcohol causes these cells to die. The thickened tissue shrinks to a more normal size. The risks and complications of heart procedure increase with age. For this reason, ablation may be preferred to myectomy in older patients with other medical conditions
- Surgically implanted devices: Surgeons can implant several types of devices in the body to help the heart work better, including:
- Pacemaker: This small device uses electrical pulses to prompt the heart to beat at a normal rate.
- : This device coordinates contractions between the heart’s left and right ventricles.
- Left ventricular assist device (LVAD): This implantable device helps the heart pump blood to the body. An LVAD can be used for long-term therapy or as an interim treatment for those awaiting a heart transplant.
- (ICD): An ICD helps maintain a normal heartbeat by sending an electric shock to the heart if an arrhythmia is detected.
- Heart transplant: A person’s diseased heart is replaced with a healthy donor heart. A heart transplant is a last resort for people who have end-stage heart failure. (End-stage means that all other treatment options have been explored, without success.)
How can cardiomyopathy be prevented?
Cardiomyopathy can be acquired when it develops due to other diseases or conditions or it may be inherited. The cause is not always known. Prevention is taking steps to lower your risk for conditions that may lead to (or complicate) cardiomyopathy, such as coronary heart disease, high blood pressure and heart attack.
Cardiomyopathy can be caused by an underlying disease or condition. Treating that initial problem early may help prevent the complications presented by cardiomyopathy. For example, to control high blood pressure, high blood cholesterol and diabetes:
- Get regular checkups with your health care professional.
- Follow your health care professional's advice about lifestyle changes.
- Take all your medications exactly as prescribed.
