What is hypertrophic cardiomyopathy? — Hypertrophic cardiomyopathy is a condition that causes the muscle in the heart to get too bulky (figure 1). When this happens, the heart can have trouble pumping blood as well as it should. This can lead to symptoms, such as trouble breathing, chest pain, and fainting. Hypertrophic cardiomyopathy is caused by a genetic problem that runs in families.
What are the symptoms of hypertrophic cardiomyopathy? — Most people with hypertrophic cardiomyopathy have no symptoms. When symptoms do occur, they can start during childhood, the teenage years, or adulthood.
Symptoms can include:
●Trouble breathing, especially during exercise
●Feeling tired
●Chest pain, which sometimes gets worse with activity
●Fainting or feeling like you might faint
●Feeling as though your heart is beating very fast or skipping beats
Is there a test for hypertrophic cardiomyopathy? — Yes. If your doctor or nurse suspects you have hypertrophic cardiomyopathy, they will probably order a test called an "echocardiogram" (figure 2). An echocardiogram, or "echo," uses sound waves to create an image of the heart. This allows doctors to measure the thickness of the walls of the heart, measure the size of the spaces or "chambers" inside the heart, and see how the heart pumps. Depending on your situation, you might also need other tests.
Your doctor will probably also order an "electrocardiogram," also called an "ECG" (figure 3). This test measures the electrical activity in your heart. It can show if your heart beats in a normal pattern and rhythm.
Since hypertrophic cardiomyopathy runs in families, your doctor or nurse might suggest testing your family members for the disorder, too.
What problems can hypertrophic cardiomyopathy cause? — In many cases the condition causes no problems. But in some cases it can lead to:
●Heart failure, a condition in which the heart does not pump as well as it should
●Heart rhythm disorders
●Stroke
●Infection of a heart valve
●Sudden death
How is hypertrophic cardiomyopathy treated? — Many people with hypertrophic cardiomyopathy do not need treatment. For people who need treatment, the type of treatment depends on what symptoms they have and how severe their condition is.
Treatments can include:
●Medicines to relieve chest pain or trouble breathing
●Medicines to control the heart's rhythm
●Surgery to implant a device called an "implantable cardioverter-defibrillator," or "ICD." (This device can get the heart beating normally again if it goes out of rhythm.)
●Surgery or other treatments to remove parts of the heart muscle. (This is done only when medicines do not work.)
What if I want to get pregnant? — Talk to your doctor before you start trying to get pregnant. Most people with hypertrophic cardiomyopathy are able to have normal pregnancies. But some need to change their medicines before they start trying to have a baby.
Is there anything I can do on my own to protect my heart and my health? — Yes. You should be careful to always drink enough water. People with hypertrophic cardiomyopathy sometimes have problems, such as fainting, when they do not get enough fluids. On the other hand, some people with hypertrophic cardiomyopathy have to be careful if they have too much salt and water. Ask your doctor about how much salt is OK to have in your diet.
It’s also important that you ask your doctor what types of physical activity are safe for you. In many cases, people with hypertrophic cardiomyopathy need to avoid some kinds of activity.
