Rheumatic Heart Disease
Medically reviewed by Drugs.com. Last updated on Jun 2, 2025.
Rheumatic heart disease (RHD) is permanent heart valve damage that develops because of rheumatic fever. Rheumatic fever is an autoimmune response to a group A strep (GAS) bacterial infection that is not fully treated. The bacteria can cause infections such as strep throat, scarlet fever, or impetigo. Your immune system overreacts to the bacteria. This causes inflammation to build up in many areas of your body, including your heart. You may develop RHD right away after 1 strep infection. RHD may develop 20 or 30 years later, or after several infections.

- Your heart beats faster than usual.
- You feel your heart flutter often.
- You have questions or concerns about your condition or care.
Medicines:
You may need any of the following:
- Blood thinners help prevent blood clots. Clots can cause strokes, heart attacks, and death. Many types of blood thinners are available. Your healthcare provider will give you specific instructions for the type you are given. The following are general safety guidelines to follow while you are taking a blood thinner:
- Watch for bleeding and bruising. Watch for bleeding from your gums or nose. Watch for blood in your urine and bowel movements. Use a soft washcloth on your skin, and a soft toothbrush to brush your teeth. This can keep your skin and gums from bleeding. If you shave, use an electric shaver. Do not play contact sports.
- Tell your dentist and other healthcare providers that you take a blood thinner. Wear a bracelet or necklace that says you take this medicine.
- Do not start or stop any other medicines or supplements unless your healthcare provider tells you to. Many medicines and supplements cannot be used with blood thinners.
- Take your blood thinner exactly as prescribed by your healthcare provider. Do not skip a dose or take less than prescribed. Tell your provider right away if you forget to take your blood thinner, or if you take too much.
- Steroids may be given to decrease inflammation.
- NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions.
- Diuretics may be given to help your body get rid of extra fluid. Diuretics will make you urinate more often.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
Manage or prevent RHD:
- Always have strep throat, scarlet fever, or impetigo fully treated. Rheumatic fever can develop again, even after treatment. Get tested for a GAS infection as soon as symptoms develop. You will need antibiotics to treat the infection. It is important to take every dose, even if you feel better sooner.
- Talk to your healthcare provider about pregnancy. Pregnancy makes your heart work harder. You and your baby may need to be monitored by specialists during your pregnancy.
- Ask about vaccines you may need. Vaccines help lower your risk for infections that can lead to disease. Get a flu vaccine as soon as recommended each year, usually in September or October. Get a COVID-19 vaccine as often as recommended. Your provider can tell you if you also need other vaccines, and when to get them.
- Be physically active, as directed. Physical activity, such as exercise, can help improve heart health. Ask your provider which activities are safe for you to do. The amount and type of exercise that is safe may depend on how severe your condition is.
- Do not smoke. Nicotine and other chemicals in cigarettes and cigars can cause lung and heart damage. Ask your provider for information if you currently smoke and need help to quit. E-cigarettes and smokeless tobacco still contain nicotine. Talk to your provider before you use these products.
- Limit or do not drink alcohol. Alcohol can raise your blood pressure and put stress on your heart. Your provider can tell you how many drinks are okay to have within 24 hours or within 1 week. A drink of alcohol is 12 ounces of beer, 5 ounces of wine, or 1½ ounces of liquor.
- Limit sodium (salt) as directed. Too much sodium can affect your fluid balance. Check labels to find low-sodium or no-salt-added foods. You can also make small changes to get less salt. For example, if you add salt while you cook, do not add more salt at the table. Ask your healthcare provider or dietitian for more ways to cut down on salt.
- Eat heart-healthy foods. Heart-healthy foods include salmon, tuna, walnuts, whole-grain breads, low-fat dairy products, beans, and oils such as olive or canola oil. A dietitian or your provider can give you more information on meal plans such as the DASH (Dietary Approaches to Stop Hypertension) eating plan. The DASH plan is low in sodium, processed sugar, unhealthy fats, and total fat. It is high in potassium, calcium, and fiber. These can be found in vegetables, fruit, and whole-grain foods.
Follow up with your doctor or cardiologist as directed:
You may need to return regularly for tests to check your heart. Write down your questions so you remember to ask them during your visits.
