Condition Basics
What is left ventricular hypertrophy (LVH)?
Left ventricular hypertrophy (LVH) means that the muscle of the heart's main pump (left ventricle) has become thick and enlarged. This can happen over time if the left ventricle has to work too hard. This part of the heart needs to be strong to pump oxygen-rich blood to your entire body. When the ventricle gets thick, other changes can happen in the heart. The heart's electrical system might not work normally, the heart muscle may not get enough oxygen, and the heart may not pump as well as it should.
What causes it?
LVH is usually caused by high blood pressure. It may also be caused by a heart problem, such as hypertrophic cardiomyopathy or a heart valve problem like aortic valve stenosis.
What are the symptoms?
LVH may not cause symptoms. When it does, the most common ones are:
- Shortness of breath.
- Feeling tired or dizzy.
- Chest pain, which may be worse when you're active.
- Feeling like your heart is fluttering, racing, or pounding (palpitations).
New or worse symptoms may be a sign of heart failure. Heart failure means that your heart doesn't pump as much blood as your body needs.
How is it diagnosed?
Your doctor will do a physical exam and ask you about any health problems you've had. You'll also be asked if any family members have or had heart disease or died suddenly from heart problems.
You may have tests such as an echocardiogram, an electrocardiogram (ECG or EKG), or an MRI of the heart.
How is LVH treated?
Treatment will depend on what caused LVH. For many people, the focus will be on treating high blood pressure. Getting high blood pressure under control may keep LVH from getting worse. This can help prevent heart failure. It can also help lower the risk of heart attack and stroke.
Medicines and lifestyle changes are used to treat high blood pressure. It may take some time to find the right medicine or medicines for you. Work with your doctor by taking your medicines as prescribed and going to all of your follow-up appointments.
If LVH was caused by a heart problem, you may have other treatment options. Treatment may help lower your risk of heart failure and other serious problems.
How can you care for yourself at home?
Healthy habits are important for your heart. Taking an active role in your treatment can help you feel better and protect your health.
- Be more active. Talk to your doctor before starting an exercise program. You can create a plan to help keep your heart and body healthy. Your doctor might suggest that you get 30 minutes of exercise most days of the week.
- Eat heart-healthy foods. These foods include vegetables, fruits, nuts, beans, lean meat, fish, and whole grains. Limit sodium, alcohol, and sugar.
- Stay at a weight that's healthy for you. Talk to your doctor if you need help losing weight.
- Take your medicines exactly as prescribed. Do not stop or change your medicines without talking to your doctor first. Talk to your doctor if you have problems with your medicines.
- If you smoke, vape, or use other tobacco or nicotine products, try to quit or cut back as much as you can. If you need help, talk to your doctor about quit programs and medicines. These can increase your chances of quitting for good.
- Manage other health problems. These include diabetes and high cholesterol. If you think you may have a problem with alcohol or drug use, talk to your doctor.
