A heart murmur is an extra sound that your heart makes when it pumps blood. This sound occurs when blood flows through the heart in an abnormal way. Heart murmurs can be either innocent or pathological.
Innocent heart murmurs are common and do not cause any problems. They are usually caused by normal variations in the heart's structure or blood flow. Pathological heart murmurs are caused by an underlying heart condition, such as a heart defect or heart disease. These murmurs can be a sign of a serious problem and may require treatment.
In this informatical article, we will discuss what a heart murmur is, the different types of heart murmurs, and what causes them. We will also provide information on how to diagnose and treat heart murmurs.
What is a Heart Murmur
A heart murmur is an extra sound that your heart makes when it pumps blood.
- Abnormal blood flow through heart
- Can be innocent or pathological
- Innocent murmurs are common
- Pathological murmurs indicate heart condition
- Can be a sign of a serious problem
- Diagnosis involves listening to heart
- Treatment depends on underlying cause
Heart murmurs can be detected during a routine physical exam. Your doctor will listen to your heart with a stethoscope to check for any abnormal sounds.
Abnormal Blood Flow Through Heart
Blood normally flows through the heart in a smooth and orderly fashion. However, if there is an obstruction or defect in the heart, blood flow can become turbulent and cause a heart murmur.
There are a number of different things that can cause abnormal blood flow through the heart, including:
- Heart defects: Congenital heart defects are heart defects that are present at birth. These defects can affect the structure of the heart, the valves of the heart, or the blood vessels that connect to the heart. Congenital heart defects can cause abnormal blood flow through the heart and lead to a heart murmur.
- Heart disease: Heart disease is a general term for conditions that affect the heart. Heart disease can damage the heart muscle, the valves of the heart, or the blood vessels that connect to the heart. Heart disease can also lead to abnormal blood flow through the heart and a heart murmur.
- Other conditions: Certain other conditions can also cause abnormal blood flow through the heart and a heart murmur. These conditions include anemia, thyroid problems, and pregnancy.
The type of heart murmur that you have depends on the underlying cause of the abnormal blood flow. Innocent heart murmurs are usually caused by normal variations in the heart's structure or blood flow. Pathological heart murmurs are caused by an underlying heart condition, such as a heart defect or heart disease.
If you have a heart murmur, your doctor will listen to your heart with a stethoscope to determine the type of murmur you have and the underlying cause. Treatment for a heart murmur depends on the underlying cause.
Can Be Innocent or Pathological
Heart murmurs can be either innocent or pathological. Innocent heart murmurs are common and do not cause any problems. Pathological heart murmurs are caused by an underlying heart condition and may require treatment.
- Innocent heart murmurs:
Innocent heart murmurs are common and do not cause any problems. They are usually caused by normal variations in the heart's structure or blood flow. Innocent heart murmurs are often heard in children and young adults. They typically disappear as the person gets older.
- Pathological heart murmurs:
Pathological heart murmurs are caused by an underlying heart condition, such as a heart defect or heart disease. Pathological heart murmurs can be a sign of a serious problem and may require treatment. Pathological heart murmurs can occur at any age, but they are more common in older adults.
The type of heart murmur that you have depends on the underlying cause of the abnormal blood flow. Your doctor will listen to your heart with a stethoscope to determine the type of murmur you have and the underlying cause. Treatment for a heart murmur depends on the underlying cause.
Innocent Murmurs Are Common
Innocent heart murmurs are very common, especially in children and young adults. Up to 50% of children have an innocent heart muur at some point in their lives. Innocent heart murmurs are usually caused by normal variations in the heart's structure or blood flow. For example, a heart muur can be caused by the following:
- A thin chest wall: A thin chest wall can make it easier to hear the sounds of the heart. This is why innocent heart murmurs are often heard in children and young adults, who typically have thinner chest walls than older adults.
- An athletic heart: An athletic heart is a heart that has been enlarged by regular exercise. This can cause the heart to make a louder sound when it pumps blood. Innocent heart murmurs are often heard in athletes.
- Anemia: Anemia is a condition in which the body does not have enough healthy red blood cells. This can cause the blood to flow more quickly through the heart, which can cause an innocent heart muur.
- Pregnancy: Pregnancy can also cause an innocent heart muur. This is because the heart has to pump more blood to support the growing baby.
Innocent heart murmurs usually do not cause any symptoms and do not require treatment. However, if you have an innocent heart muur and you are experiencing any symptoms, such as shortness of breath, chest pain, or fainting, you should see a doctor immediately.
Innocent heart murmurs can be diagnosed with a physical exam by listening to the heart with a stethoscope. Your doctor will be able to tell if you have an innocent heart muur based on the sound of the muur and your medical history.
Pathological Murmurs Indicate Heart Condition
Pathological heart murmurs are caused by an underlying heart condition, such as a heart defect or heart disease. These murmurs can be a sign of a serious problem and may require treatment.
There are a number of different heart conditions that can cause a pathological heart murmur, including:
- Congenital heart defects: Congenital heart defects are heart defects that are present at birth. These defects can affect the structure of the heart, the valves of the heart, or the blood vessels that connect to the heart. Congenital heart defects can cause a pathological heart murmur.
- Heart valve problems: Heart valve problems can occur when the valves of the heart do not open or close properly. This can cause blood to leak back through the valve, which can cause a pathological heart murmur.
- Cardiomyopathy: Cardiomyopathy is a condition in which the heart muscle is weakened or enlarged. This can make it difficult for the heart to pump blood effectively, which can cause a pathological heart murmur.
- Infective endocarditis: Infective endocarditis is an infection of the lining of the heart. This infection can damage the heart valves and cause a pathological heart murmur.
The type of heart murmur that you have depends on the underlying cause of the heart condition. Your doctor will listen to your heart with a stethoscope to determine the type of murmur you have and the underlying cause. Treatment for a pathological heart murmur depends on the underlying cause.
If you have a pathological heart murmur, your doctor will recommend the best course of treatment for you. Treatment may include medication, surgery, or a combination of both.
Can Be a Sign of a Serious Problem
Pathological heart murmurs can be a sign of a serious problem, such as a heart defect or heart disease. These conditions can lead to a number of health problems, including:
- Heart failure: Heart failure is a condition in which the heart is unable to pump blood effectively. This can lead to a number of problems, such as shortness of breath, fatigue, and swelling in the feet and ankles.
- Stroke: A stroke occurs when the blood supply to the brain is interrupted. This can be caused by a blood clot that forms in the heart and travels to the brain. Strokes can cause a variety of problems, including paralysis, difficulty speaking, and memory loss.
- Heart attack: A heart attack occurs when blood flow to the heart is blocked. This can be caused by a blood clot that forms in the heart's arteries. Heart attacks can be fatal.
If you have a pathological heart murmur, it is important to see a doctor right away to determine the underlying cause. Treatment for the underlying cause can help to prevent these serious complications.
If you have a heart murmur, your doctor will ask you about your symptoms and medical history. They will also perform a physical exam and listen to your heart with a stethoscope. Your doctor may also order some tests, such as an electrocardiogram (ECG), a chest X-ray, or an echocardiogram (a type of ultrasound that allows your doctor to see the structure of your heart).
Diagnosis Involves Listening to Heart
A heart murmur is diagnosed by listening to the heart with a stethoscope. This is a simple and painless procedure that can be performed in a doctor's office or clinic.
- Listening for abnormal sounds:
When your doctor listens to your heart with a stethoscope, they are listening for any abnormal sounds, such as a heart murmur. Heart murmurs can sound like a whooshing, swishing, or blowing sound.
- Determining the location of the murmur:
Your doctor will also try to determine the location of the murmur. This can help to identify the underlying cause of the murmur.
- Assessing the severity of the murmur:
Your doctor will also assess the severity of the murmur. This is based on how loud the murmur is and how long it lasts.
- Listening for other heart problems:
Your doctor will also listen for other heart problems, such as an irregular heartbeat or a heart murmur.
In some cases, your doctor may order additional tests to confirm the diagnosis of a heart murmur. These tests may include:
- Electrocardiogram (ECG)
- Chest X-ray
- Echocardiogram
These tests can help your doctor to see the structure of your heart and determine the underlying cause of the heart murmur.
Treatment Depends on Underlying Cause
The treatment for a heart murmur depends on the underlying cause. If the heart murmur is caused by an innocent condition, such as a thin chest wall or an athletic heart, no treatment is necessary. However, if the heart murmur is caused by an underlying heart condition, treatment will be necessary to address the underlying condition.
- Treatment for heart defects:
Treatment for heart defects depends on the type of defect. Some heart defects can be treated with medication, while others may require surgery.
- Treatment for heart valve problems:
Treatment for heart valve problems depends on the type of valve problem. Some valve problems can be treated with medication, while others may require surgery.
- Treatment for cardiomyopathy:
Treatment for cardiomyopathy depends on the type of cardiomyopathy. Some types of cardiomyopathy can be treated with medication, while others may require surgery or a heart transplant.
- Treatment for infective endocarditis:
Treatment for infective endocarditis typically involves antibiotics to treat the infection. In some cases, surgery may be necessary to repair or replace a damaged heart valve.
If you have a heart murmur, your doctor will work with you to determine the best course of treatment for you. Treatment may include medication, surgery, or a combination of both.
