A heart murmur is an extra or unusual sound made by blood moving through the heart. A healthcare professional may hear it while listening to your heart with a stethoscope. A murmur is a clinical finding, not a diagnosis. Some murmurs are harmless and may not need treatment, while others can be linked to a heart or valve problem.

Because the possible causes vary, heart murmur treatment cannot be chosen safely based on the sound alone. Your healthcare professional may consider your symptoms, medical history, age, and examination findings to determine whether further evaluation or care is needed.

What determines heart murmur treatment?

Treatment depends first on whether the murmur is innocent or linked to a heart problem. An innocent murmur may occur without an underlying structural abnormality and may require only observation. A murmur associated with valve disease, a congenital heart problem, or another condition may need additional care.

Your healthcare professional may consider your age, symptoms, medical history, and findings from a physical examination. Test results, when needed, can provide more information about the heart’s structure and function. If there is no active problem requiring treatment, follow-up appointments may be recommended to monitor for changes. This is not the same as neglect: keeping scheduled visits and reporting new symptoms helps your care team decide whether the plan should change.

How doctors evaluate a heart murmur

Evaluation usually begins with questions about your medical history, health conditions, medicines, and any symptoms. Your healthcare professional may ask about chest discomfort, fainting, shortness of breath, swelling, or changes in your heartbeat. During a physical examination, they listen to your heart with a stethoscope and consider the murmur’s timing and sound, along with other findings.

Further testing depends on what the examination suggests. Possible tests include:

  • An echocardiogram, which uses sound waves to create images of the heart and show how it is structured and working
  • An electrocardiogram, which records the heart’s electrical activity
  • Chest imaging or other tests may help clarify the cause

Not everyone needs every test. Your symptoms, age, medical history, examination findings, and the suspected cause guide the evaluation.

When an innocent murmur needs no treatment

Some murmurs occur without an underlying structural heart problem. When a healthcare professional has evaluated the murmur and considers it innocent, medication, a procedure, or activity restrictions may not be needed. However, a murmur should not be assumed to be innocent without appropriate assessment, especially if symptoms or other concerning findings are present.

Follow the monitoring plan recommended by your healthcare professional, since follow-up may vary based on your age, health history, examination, and test results. Report any new or changing symptoms promptly so your care team can reassess whether the plan needs to be adjusted.

Treating an underlying heart condition

When a murmur is linked to a heart condition, treatment focuses on that underlying problem rather than the sound itself. For valve disease, care may include monitoring, medicines for related concerns, or a procedure when clinically appropriate. A congenital heart problem may require observation, ongoing specialist care, or treatment, depending on its severity and how it affects the heart.

If an infection or another heart-related issue is contributing to the murmur, your healthcare professional will determine the appropriate evaluation and care. The plan depends on the specific condition, its severity, your symptoms, test results, age, and overall health. Because there is no single treatment for every murmur, follow your healthcare professional’s recommendations and ask what follow-up is needed.

Medicines that may be part of treatment

Medicines may be prescribed when a heart murmur is linked to another cardiovascular concern. Depending on the individual situation, treatment may address:

  • Fluid buildup
  • Abnormal blood pressure
  • Heart rhythm problems
  • Other effects of an underlying heart condition

These medicines treat the associated problem, not necessarily the murmur itself. A murmur may remain even when a related condition is being managed, and not every murmur requires medication. Do not start or stop a medicine based on the presence of a murmur. Supplements or natural products should not replace prescribed treatment, and they may interact with medicines or be unsuitable for some heart conditions. Discuss any medicine, supplement, or proposed change with a qualified healthcare professional first.

When procedures or surgery may be considered

Some significant valve or structural heart problems may require more than monitoring or medicines. In selected situations, care may involve a catheter-based procedure, which uses a thin tube to reach the heart, or surgery. These options are not routine treatments for a heart murmur itself. They are considered when an underlying condition affects how the heart works or creates a significant health concern.

The decision depends on the echocardiogram and other test results, symptoms, the severity of the condition, overall health, and how the problem affects the heart. A heart specialist can explain whether a procedure or surgery is appropriate and discuss the available options. Do not assume that hearing a murmur means an intervention is needed; individualized assessment is essential.

Heart murmur treatment in children and pregnancy

Children and pregnant people may need context-specific evaluation because age, development, pregnancy-related changes, health history, and symptoms can affect how a murmur is assessed. Some murmurs may be innocent in children or during pregnancy and may not require active treatment after appropriate evaluation.

However, age or pregnancy alone should not be used to assume that a murmur is harmless. Symptoms such as chest discomfort, fainting, shortness of breath, blue or gray coloring, swelling, or a rapid or irregular heartbeat require prompt medical assessment. A healthcare professional can determine whether monitoring, testing, or other care is appropriate for the individual situation. Follow the recommended plan and discuss any new or changing symptoms with your care team.

Symptoms that need prompt medical attention

Some symptoms may signal a serious heart or circulation problem. Do not wait for a routine appointment if symptoms are severe, sudden, or getting worse. Seek emergency medical help for:

  • Chest pain or pressure
  • Fainting or loss of consciousness
  • Severe or worsening shortness of breath
  • Blue or gray coloring of the lips, skin, or face
  • A rapid or irregular heartbeat along with chest discomfort, fainting, or shortness of breath
  • Marked swelling, especially if it develops suddenly
  • Sudden overall deterioration or a feeling that something is seriously wrong

Less severe but new or persistent symptoms—such as increasing fatigue, swelling, or changes in heartbeat—still warrant a timely appointment. Contact a healthcare professional for guidance rather than assuming the murmur is harmless.

Can lifestyle changes treat a heart murmur?

Lifestyle practices can support overall cardiovascular health, but they do not correct every cause of a heart murmur or replace medical evaluation and prescribed treatment. Nutritious eating, regular, appropriate activity, adequate sleep, stress management, and avoiding tobacco may all support your overall well-being.

Ask your healthcare professional what level and type of activity is suitable for you. This is especially important if you have symptoms or a diagnosed heart condition, since some people may need specific guidance about exercise. Do not use lifestyle changes to delay recommended testing, follow-up, medicines, or other care. The right plan depends on what is causing the murmur and how it affects your heart.

Natural approaches, supplements, and homeopathy

Some people are interested in homeopathy, herbs, supplements, or other complementary approaches when seeking treatment for a heart murmur. These practices may have a place in a person’s broader wellness plan, but they should not replace evaluation or treatment for a heart murmur. A murmur can be linked to an underlying heart condition that may require monitoring, medication, or other care.

Talk with a qualified healthcare professional before using any supplement or changing your treatment plan. Products may interact with medicines or be unsuitable for certain heart conditions. Share a complete list of products you use, including herbal preparations and homeopathic products, so your care team can help you make informed, safer choices.

Questions to ask your healthcare professional

  • What may be causing the murmur, and is it innocent or related to a heart condition?
  • Which tests, if any, are needed to evaluate it?
  • Are there any activity, dental care, or medication instructions for my child or me?
  • What follow-up appointments or monitoring will be needed?
  • Which new or worsening symptoms should prompt urgent or emergency care?

Key points to remember

A heart murmur is a sound, not a diagnosis. Treatment depends on its cause and whether it is linked to a heart condition. Some innocent murmurs need only observation and follow-up, while others may require medicines, procedures, or additional care. Seek urgent medical help for warning signs such as chest pain, fainting, severe shortness of breath, blue or gray coloring, marked swelling, or sudden deterioration. Follow individualized medical advice rather than trying to diagnose or treat a murmur yourself.
