Endocarditis is an infection of the tissue that lines the inside of your heart. Many times it also affects valves of your heart. Endocarditis, and the health problems it may cause, can be serious and can become life-threatening.



You may need any of the following:

  • Antibiotics help treat or prevent a bacterial infection.

  • Blood pressure medicine is given to decrease your blood pressure.

  • Heart medicine is given to strengthen or regulate your heartbeat.

  • Diuretics decrease excess fluid. You may urinate more often when you take this medicine.

  • Pain medicine may be given.

  • Anticoagulants are a type of blood thinner medicine that helps prevent clots. Clots can cause strokes, heart attacks, and death. These medicines may cause you to bleed or bruise more easily.

    • Watch for bleeding from your gums or nose. Watch for blood in your urine and bowel movements. Use a soft washcloth and a soft toothbrush. If you shave, use an electric razor. Avoid activities that can cause bruising or bleeding.

    • Tell your healthcare provider about all medicines you take because many medicines cannot be used with anticoagulants. Do not start or stop any medicines unless your healthcare provider tells you to. Tell your dentist and other healthcare providers that you take anticoagulants. Wear a bracelet or necklace that says you take this medicine.

    • You will need regular blood tests so your healthcare provider can decide how much medicine you need. Take anticoagulants exactly as directed. Tell your healthcare provider right away if you forget to take the medicine, or if you take too much.

    • If you take warfarin, some foods can change how your blood clots. Do not make major changes to your diet while you take warfarin. Warfarin works best when you eat about the same amount of vitamin K every day. Vitamin K is found in green leafy vegetables, broccoli, grapes, and other foods. Ask for more information about what to eat when you take warfarin.

  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him 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.

Follow up with your cardiologist as directed:

You may need to return for more tests. Write down your questions so you remember to ask them during your visits.


  • Adjust your activities as directed. You may need to decrease your activities or exercise while you have symptoms. Ask your PHP about the best exercise plan for you.

  • Eat heart healthy foods. Foods that help protect the heart include fruits, vegetables, nuts, salmon, and canola and soybean oils. You may be told to eat foods low in cholesterol or sodium (salt) or high in fiber. You also may be told to limit saturated and trans fats. Ask your PHP or nutritionist for more information on a heart healthy diet.

  • Maintain a healthy weight. Ask your PHP how much you should weigh. Ask him to help you create a weight loss plan if you are overweight.

  • Do not smoke. If you smoke, it is never too late to quit. Ask for information if you need help quitting.

Prevent endocarditis:

  • Keep your teeth and gums healthy. Brush your teeth 2 to 3 times every day. It is best to brush your teeth after meals. Gently brush your teeth and gums with a clean toothbrush that has soft bristles. See your dentist for regular checkups. Always tell your dental caregivers that you have had endocarditis.

  • Ask your healthcare provider if you should take antibiotics before certain procedures. Some procedures may allow bacteria to get into your blood and travel to your heart. You may need medicine to prevent a bacterial infection.

Contact your cardiologist if:

  • You have a fever.

  • You lose your appetite or are unable to eat.

  • You have increased fatigue and weakness.

  • You have questions or concerns about your condition or care.
