Is a Heart Murmur a Danger to My Health?

The word “murmur” sounds mysterious, and anything involving the heart tends to raise anxiety fast. At Healing Hearts Clinic, we understand that fear. We also want you to know that a heart murmur doesn’t always indicate a serious problem.

In fact, studies show that less than a third of people with heart murmurs who undergo specialized tests turn out to have problems like valvular heart disease (VHD).

A heart murmur means we hear an extra or unusual sound during the heartbeat. Instead of the normal “lub-dub” sound, blood makes a whooshing, swishing, or humming noise as it moves through the heart. We usually hear it with a stethoscope during a routine exam.

Some heart murmurs don’t cause harm and don’t need treatment. Others point to a condition that needs closer care. The key lies in finding out what type of murmur you have and what’s causing it.

Causes of heart murmurs

Your heart has four chambers and four valves. The valves open and close to allow blood to move in the right direction. When blood flows faster than usual or passes through a narrowed, leaky, or stiff valve, it can create a murmur.

Some people have what doctors call an innocent or harmless murmur that doesn’t come from heart disease. It often happens when blood moves quickly through a healthy heart. Children, teens, pregnant women, and people with fever, anemia, or thyroid problems sometimes have innocent murmurs.

Other murmurs occur due to a structural heart problem. These may include the following:

You can’t tell how serious a murmur is just by how it sounds to you, and many people don’t feel anything at all. We listen for clues, including how loud the murmur sounds, where it occurs in the heartbeat, where it’s heard best, and whether the sound spreads to other areas.

Symptoms also matter. A murmur needs prompt medical attention if you also have:

These symptoms don’t always mean you have a dangerous heart condition, but they do mean your heart needs a closer look.

Heart murmur tests

A murmur’s cause matters more than the sound itself. We take the time to learn about your symptoms, medical history, and risk factors, and then typically perform one or more tests. These help us distinguish harmless murmurs from those that require treatment.

We typically recommend an echocardiogram, an ultrasound test that shows your heart’s chambers, valves, and blood flow. It helps us see whether a valve leaks, narrows, or works normally. The test doesn’t hurt and gives us detailed information about your heart’s structure.

We may also recommend an electrocardiogram (EKG) to check your heart rhythm. Some patients may need a chest X-ray, blood tests, a stress test, or a heart monitor, depending on their symptoms and exam findings.

Heart murmur treatment

Some heart murmurs don’t need treatment at all. If your murmur is due to normal blood flow and your heart appears healthy, we may monitor it during future visits. You can usually exercise, work, and live a normal life.

If a condition that’s unrelated to your heart causes a murmur, treatment focuses on that condition. For example, anemia, fever, or thyroid disease can make the heart work harder, creating a murmur. Treating the underlying problem often improves the murmur.

Valve problems may need long-term monitoring, medication, or a minimally invasive procedure. Mild valve changes often remain stable for years, but more serious valve disease may require treatment to help the heart pump effectively and prevent complications.

Finding a murmur early gives you more control. It lets you track changes, protect your heart, and get care before symptoms worsen.

Visiting a heart specialist

You should schedule an evaluation if your primary care provider hears a new murmur, if you have heart-related symptoms, or if you have a known valve condition that needs follow-up.

You should also seek care if you have a family history of heart valve disease, congenital heart problems, or sudden cardiac death.

At Healing Hearts Clinic, we help patients understand what their heart murmur means without panic or confusion. We explain test results in clear language, answer questions, and create a care plan that fits your needs. Call us or get in touch by completing the online form.
