Heart Murmur: Care Instructions
Your Care Instructions
A heart murmur is a blowing, whooshing, or rasping sound made by blood moving through the heart or the blood vessels near the heart. Murmurs can be heard through a stethoscope.
Heart murmurs can occur during pregnancy or during a temporary illness, such as a fever. These murmurs usually are not a problem and go away on their own.
However, sometimes a heart murmur is a sign of a serious problem, such as congenital heart disease or heart valve problems, that may need treatment. You may need more tests to check your heart. The treatment depends on the specific heart problem causing the murmur.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
How can you care for yourself at home?
- Take your medicines exactly as prescribed. Call your doctor if you think you are having a problem with your medicine. You will get more details on the specific medicines your doctor prescribes.
- Follow a heart-healthy lifestyle to help keep your heart and body healthy.
- Do not smoke. Smoking increases your risk of heart attack and stroke. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good.
- Eat heart-healthy foods such as fruits, vegetables, whole grains, fish, lean meats, and low-fat or non-fat dairy foods. Limit sodium, sugars, and alcohol.
- If your doctor recommends it, get more exercise. Walking is a good choice. Bit by bit, increase the amount you walk every day. Try for 2½ hours a week. You also may want to swim, bike, or do other activities.
- Stay at a healthy weight. Lose weight if you need to.
