Have you ever heard the term “heart murmur” and wondered what it actually means? Does it mean something is wrong with the heart? Should you be worried if a doctor detects one? Let’s break it down in simple terms so you can understand everything you need to know about heart murmurs.
What is a Heart Murmur?
Think of your heart as a pump that keeps blood flowing smoothly through your body. Normally, this process is silent. But sometimes, when a doctor listens with a stethoscope, they might hear a whooshing or swishing sound—this is called a heart murmur. It’s like a gentle hum in the background of your heartbeat.
Heart murmurs are not always a sign of trouble. Some people are born with them, and they never cause any problems. Others develop murmurs due to underlying heart conditions. The key is to know when a murmur is harmless and when it needs medical attention.
Types of Heart Murmurs
There are two main types:
Innocent (Harmless) Murmurs
These murmurs don’t indicate any heart disease. They are common in children and young adults, often disappearing over time. Even athletes sometimes develop murmurs because their hearts work harder than normal.
Abnormal Murmurs
These murmurs are caused by problems in the heart, such as valve issues, congenital heart defects, or infections. If your doctor suspects an abnormal murmur, further tests might be needed to find out what’s causing it.
What Causes a Heart Murmur?
Several factors can lead to heart murmurs, including:
- Heart valve problems – Valves control blood flow in and out of the heart. If they don’t open or close properly, a murmur can occur.
- Congenital heart defects – Some babies are born with heart issues that cause murmurs.
- High blood pressure – Increased pressure on the heart can lead to abnormal murmurs.
- Anemia – Low red blood cell count forces the heart to work harder, sometimes creating a murmur.
- Infections – Conditions like endocarditis (infection of the heart’s inner lining) can lead to murmurs.
Symptoms to Watch For
Innocent murmurs usually don’t cause any symptoms. However, if the murmur is due to a heart problem, you might notice:
- Shortness of breath
- Chest pain
- Fatigue or dizziness
- Swelling in the legs or feet
- Irregular heartbeat
If you experience any of these symptoms, it’s best to consult a cardiologist to rule out any serious heart conditions.
How is a Heart Murmur Diagnosed?
A doctor usually detects a murmur during a routine check-up by listening to your heart with a stethoscope. If needed, they may recommend tests such as:
- Echocardiogram (Echo) – Uses sound waves to create images of the heart.
- Electrocardiogram (ECG) – Checks the heart’s electrical activity.
- Chest X-ray – Helps see the size and shape of the heart.
These tests help determine if the murmur is harmless or if further treatment is needed.
Can Heart Murmurs Be Treated?
Treatment depends on the cause:
- For innocent murmurs: No treatment is needed. You can live a normal, healthy life.
- For abnormal murmurs: Treatment focuses on fixing the underlying heart issue. This may include medications, lifestyle changes, or in some cases, surgery to repair damaged heart valves.
The right course of action will depend on a doctor’s evaluation. If you or a loved one has been diagnosed with a murmur, consulting the best cardiologist in Newtown at The Newtown Clinic is the best step forward.
