Heart murmurs : Causes-Symptoms-Diagnosis-Treatment

 What Are Heart Murmurs?

The "murmur" is the sound of blood flowing. it's going to be passing through an abnormal heart valve, as an example. Or it's going to be that a condition makes your heart beat quicker and forces your heart to handle additional blood faster than traditional.

Within the center, there are four chambers separated by valves that regulate what proportion of blood enters every chamber at any time. Healthy valves conjointly facilitate forestall blood from flowing within the wrong direction in your heart.

What Are Heart Murmurs?
Heart Murmurs

A healthy heart makes a "lub-dub" sound because it beats. The "lub" (systolic sound) happens once a part of the center contracts and also the mitral and angulate valves shut, and also the "dub" (diastolic sound) happens once a part of the center relaxes and also the arteria and respiratory organ valves shut. A symptom is an additional sound within the heartbeat -- like a ''whooshing'' -- that's caused by turbulent blood flow through the center valves.

Heart murmurs happen in several healthy kids, WHO might outgrow them as adults. they will conjointly happen throughout the physiological state. Such murmurs are known as "innocent" heart murmurs. they're not coupled with medical or heart conditions and don't like treatment or modus vivendi changes.

But there are exceptions. Murmurs are often coupled to a broken or overworked heart valve. Some individuals are born with valve issues. Others get them as a vicinity of aging or from different heart issues.

Medical terms

  • Heart murmurs square measure sounds — like whooshing or noisy — created by turbulent blood in or close to your heart. Your doctor will hear these sounds with a medical instrument. a traditional heartbeat makes 2 feels like "lubb-dupp" (sometimes delineated as "lub-DUP") once your heart valves square measure closing.

  • Heart murmurs may be a gift at birth (congenital) or develop later in life.

  • Heart murmurs may be harmless (innocent) or abnormal. Associate in Nursing innocent symptom isn't a symptom of cardiovascular disease and does not like treatment. Abnormal heart murmurs need follow-up testing to work out the cause. Treatment is directed at the reason behind your abnormal symptom.

  • in children When heart murmurs are discovered in a child parents sometimes feel alarmed This is especially true if they have never heard the sound before However many children with mild heart murmurs have no symptoms and do not experience any problems as a result of their condition Your pediatrician has probably detected your baby’s murmur either during regular checkups or when she was ill or injured at some point in her life

When you first are suspected of having a heart murmur your doctor will usually order an echocardiogram to check the condition of your heart Echocardiography is ultrasound imaging that uses sound waves to produce images of structures in your chest and abdomen The test can show how well your heart muscle works whether it's enlarged and if it's normal or irregular in shape It also can detect blood flow through the valves in your heart and part of your arteries This helps identify whether any of these areas might be damaged or leaking fluids

Symptoms Heart murmurs

If you have an innocent heart murmur, you likely won't have any other signs or symptoms.

An abnormal heart murmur may cause the following signs and symptoms, depending on the cause of the murmur:

  • Skin that appears blue, especially on your fingertips and lips

  • Swelling or sudden weight gain

  • Shortness of breath

  • Chronic cough

  • Enlarged liver

  • Enlarged neck veins

  • In infants, poor appetite and failure to grow normally

  • Heavy sweating with little or no activity

  • Chest pain

  • Dizziness

  • Fainting

When to see a doctor

Most heart murmurs are not serious, however if you think that you or your kid includes a murmur, build an arrangement to visualize your general practitioner. Your doctor will tell you if the guts murmur is innocent ANd does not need any|any longer|any more|from now on|to any extent further} treatment or if an underlying heart drawback has to be further examined.

Causes Heart murmurs

A heart murmur may happen:

  • When the heart is filling with blood (diastolic murmur)

  • When the heart is emptying (systolic murmur)

  • Throughout the heartbeat (continuous murmur)

A heart murmur may be innocent or abnormal.

Innocent heart murmurs

A person with an innocent murmur includes a traditional heart. This kind of symptom is common in newborns and kids.

An innocent murmur will occur once blood flows earlier than traditional through the guts. Conditions which will cause speedy blood flow through your heart, leading to associate innocent symptom, include:

  • Physical activity or exercise

  • Pregnancy

  • Fever

  • Not having enough healthy red blood cells to carry adequate oxygen to your body tissues (anemia)

  • Too much thyroid hormone in your body (hyperthyroidism)

  • Phases of rapid growth, such as adolescence

Innocent heart murmurs may disappear over time, or they may last your entire life without ever causing further health problems.

Abnormal heart murmurs

In adults, abnormal murmurs square measure most frequently because of non inheritable heart valve issues. In youngsters, abnormal murmurs square measure typically caused by structural issues of the center (congenital heart defects).

Common non inheritable defects that cause heart murmurs include:

  • Holes in the heart. Known as septal defects, holes in the heart may or may not be serious, depending on the size of the hole and its location.

  • Cardiac shunts. Cardiac shunts occur when there's an abnormal blood flow between the heart chambers or blood vessels, which may lead to a heart murmur.

  • Heart valve problems present from birth. Examples embody valves do not|that do not} permit enough blood through them (stenosis) or those who don't shut properly and leak (regurgitation).
    In older youngsters and adults, causes of abnormal heart murmurs embody infections and conditions that harm the structures of the guts. For example: 

  • Valve calcification. This hardening or thickening of valves, as in pathology|mitral valve stenosis|stenosis|stricture|valvular heart disease} or semilunar valve stenosis, will occur as you age. Valves could become narrowed (stenotic), creating it tougher for blood to flow through your heart, leading to murmurs. 

  • Endocarditis. This infection of the inner lining of your heart and valves typically occurs when bacteria or other germs from another part of your body, such as your mouth, spread through your bloodstream and get stuck in your heart.

  • Left untreated, endocarditis can damage or destroy your heart valves. This condition usually occurs in people who already have heart valve problems.

  • Rheumatic fever. Although currently rare within the US, infectious disease may be a serious condition which will occur once you do not receive prompt or complete treatment for an infection. It will for good have an effect on the guts valves and interfere with traditional blood flow through your heart. 

Risk factors Heart murmurs

You have AN enlarged risk of a cardiac murmur if somebody in your family had a heart defect related to the bizarre sounds.

Many different medical conditions will increase your risk of heart murmurs, including:

  • A weakened heart muscle (cardiomyopathy)

  • An infection of the lining of the heart (endocarditis)

  • Blood disorders marked by a high number of certain white cells, called eosinophils (hypereosinophilic syndrome)

  • Certain autoimmune disorders, including lupus and rheumatoid arthritis

  • Chemicals from a rare tumor in the lungs or gastrointestinal system that enter your bloodstream (carcinoid syndrome)

  • Heart valve disease

  • High blood pressure (hypertension)

  • High blood pressure in the lungs (pulmonary hypertension)

  • History of rheumatic fever

  • Overactive thyroid (hyperthyroidism)

Having uncontrolled polygenic disease or an epidemic roseola infection throughout physiological conditions will increase your baby's risk of developing heart defects and a cardiac murmur. Use of bound medications, alcohol or medicine throughout physiological conditions will cause heart defects in an exceedingly developing baby, which can cause a cardiac murmur.

How long can you live with a heart murmur?

A heart murmur is a medical term that describes any sort of irregularity in the sound your heart makes when it beats The human heart creates its own acoustic sound the lub-dub heard using special stethoscopes called electronic stethoscopes or Dopplers A healthy beat has two distinguishable sounds: one at the beginning as blood rushes into the body and another near the end when blood flows back out If you were to listen in on someone else's heartbeat you would hear a similar pattern (Lub! Lub! Rub!) Murmurs often develop with age but aren't necessarily life-.

How do you get rid of a heart murmur naturally?

A heart murmur which is a series of vibrations or swishing sounds made as the blood pumps around the heart muscle can be caused by atrial fibrillation or bad valves in the heart Common symptoms include continuous rapid breathing chest pain and dizziness While getting rid of a heart murmur naturally may not be considered conventional medicine you should always consult your physician before doing so.

Dr Anne Breen a veterinary cardiologist at West Veterinary Cardiology Consultants in Golden Colo. explained that heart murmurs (or cardiac arrhythmias) are almost always benign in young cats and dogs with normal hearts However feline hypertrophic cardiomyopathy is the one important exception to this rule as it can cause heart failure in younger cats In fact she said "By age 10 years or earlier we consider most cats to have established the disease.

Is garlic good for the heart?

Garlic is one of the more effective herbs for heart and circulatory health It helps to lower blood cholesterol levels and even reduce blood pressure which can help you feel better throughout the day If there’s something you should do it is to eat garlic in moderation to reap its many benefits You’ll be surprised at how quickly garlic becomes a favorite veggie or condiment in your household once you start adding it to everything from salads to stews and fried rice!.

What vitamins help with your heart?

What are the best vitamins for your heart? It's a difficult question While vitamin C combats stress and supports healthy arteries B vitamins promote good circulation omega-3 fatty acids encourage healthy blood pressure and antioxidants support your heart health by reducing damage caused by sources of inflammation in the body Recent research has found that higher antioxidant levels may reduce the risk of heart disease and stroke in women.

Although there are many supplements for heart health available the best vitamins for the heart include vitamin D and omega-3 fatty acids Vitamin D is important because it helps regulate blood pressure and strengthen both the cardiac muscle and arteries that support all of your organ systems Without enough vitamin D in your system you could experience a stroke or a heart attack Omega-3 fatty acids help to lower triglyceride levels in your bloodstream while also reducing inflammation This will allow your body to function properly without being at risk for any potentially serious ailments In fact studies show that people who do not get enough omega-3s can.

Prevention Heart murmurs

While there is not a lot you'll be able to do to forestall a murmur, it's reassuring to grasp that heart murmurs don't seem to be an unwellness and square measure usually harmless. For youngsters, several murmurs flee on their own as youngsters grow. For adults, murmurs could disappear because the underlying condition inflicting them improves.

Diagnosis Heart murmurs

Usually, doctors notice heart murmurs throughout a physical communication. Your doctor is ready to hear it once being attentive to your heart with a medical instrument.

Heart murmurs are sometimes detected once your doctor listens to your heart employing a medical instrument throughout a physical communication.

To check whether or not the murmur is innocent or abnormal, your doctor can think about the following:

  • How loud is it? This is rated on a scale from 1 to 6, with 6 being the loudest.

  • Where in your heart is it? And can it be heard in your neck or back?

  • What pitch is it? Is it high-, medium- or low-pitched?

  • What affects the sound? Does exercising or changing body position affect the sound?

  • When does it occur, and for how long? A murmur that happens once the guts is filled with blood (diastolic murmur) or throughout the heartbeat (continuous murmur) might signal a heart downside. Tests have to be compelled to be done to seek out the cause. A murmur that happens once the guts is voidance (systolic murmur) typically is an associate degree innocent symptom. Innocent heart murmurs are not proof of heart condition and do not need treatment.
    Your doctor also will hunt for alternative signs and symptoms of heart issues and raise regarding your anamnesis and whether or not alternative members of the family have had heart murmurs or alternative heart conditions. 


If your doctor thinks the heart murmur is abnormal, you or your child may need additional tests, including:

  • Echocardiogram. This check is the main check accustomed to verifying the reason for a symptom. Associate degree sonography uses ultrasound waves to make elaborate pictures of your heart's structure and performance. It will facilitate establishing abnormal heart valves, like those who are hardened (calcified) or unseaworthy, and may conjointly notice most heart defects. 

  • Chest X-ray. A chest X-ray shows an image of your heart, lungs and blood vessels. It can reveal if your heart is enlarged, which may mean an underlying condition is causing your heart murmur.

  • Electrocardiogram (ECG). In this noninvasive test, a technician will place probes on your chest that record the electrical impulses that make your heart beat. An ECG records these electrical signals and can help your doctor look for heart rhythm and structure problems.

  • Cardiac catheterization. In this check, a tubing is inserted into a vein or artery in your leg or arm till it reaches your heart. The pressure in your heart chambers is measured, and dye is injected.
    The dye is seen on AN X-ray, that helps your doctor see the blood flow through your heart, blood vessels and valves to see for issues. This check is mostly used once different tests are inconclusive. 

Treatment Heart murmurs

An innocent cardiac murmur typically does not need treatment as a result of the guts is traditional. If an innocent murmur is caused by associate ill health, like fever or associated active thyroid (hyperthyroidism), the murmur can flee once that condition is treated.

An abnormal cardiac murmur is closely monitored by your doctor over time. Treatment depends on the guts condition inflicting the murmur and should embrace medications or surgery.


The medication your doctor prescribes depends on the specific heart problem you have. Some medications your doctor might give you include:

  • Blood thinners (anticoagulants). This type of drug prevents blood clots from forming in your heart and inflicting a stroke. Your doctor might inflict ancient anticoagulants, like analgesic, anticoagulant (Jantoven) or clopidogrel (Plavix). Newer blood thinners, referred to as direct-acting oral anticoagulants (DOACs), additionally are also prescribed. Examples include apixaban (Eliquis), rivaroxaban (Xarelto), dabigatran (Pradaxa) et al. 

  • Water pills (diuretics). Diuretics remove excess fluid from your body, which can help treat other conditions that might worsen a heart murmur, such as high blood pressure.

  • Angiotensin-converting enzyme (ACE) inhibitors. ACE inhibitors lower your blood pressure. High blood pressure can worsen underlying conditions that cause heart murmurs.

  • Statins. Statins help lower your cholesterol. Having high cholesterol seems to worsen some heart valve problems, including some heart murmurs.

  • Beta blockers. These medications lower your pulse rate and force per unit area. They are used for a few styles of heart valve issues.
    Doctors suggest that the majority of folks with abnormal heart murmurs take antibiotics before visiting the tooth doctor or having surgery to forestall bacteria from going in the liner of the guts (infective endocarditis).
    Doctors do not suggest antibiotics before procedures, apart from those that have a man-made heart valve, history of a heart valve infection or an inborn heart defect that will increase the danger of infective carditis. 


Surgery could also be required to correct a broken or leaky valve that causes a cardiac murmur. reckoning on your cardiovascular disease, your doctor could suggest one among many heart valve treatment choices.

Valve repair

To repair a valve, your doctor may recommend one of the following procedures:

  • Balloon valvuloplasty. This procedure is performed to relieve a narrowed valve. During a balloon valvuloplasty, a small catheter containing an expandable balloon is threaded into your heart, placed into the valve and then expanded to help widen the narrowed valve.

  • Annuloplasty. In this procedure, your operating surgeon tightens the tissue round the valve by implanting a synthetic ring. This permits the leaflets to come back along and shut the abnormal gap through the valve. 

  • Repair of structural support. In this procedure, your surgeon replaces or shortens the cords that support the valves (chordae tendineae and papillary muscles) to repair the structural support. When the cords and muscles are the right length, the valve leaflet edges meet and eliminate the leak.

  • Valve leaflet repair. In valve leaflet repair, your surgeon surgically separates, cuts or pleats a valve flap (leaflet).

Valve replacement

In many cases, the valve has to be replaced. Options include:

  • Open-heart surgery. This is the best treatment for severe valve stricture. Your doctor removes the narrowed valve and replaces it with a mechanical valve or a tissue valve. Mechanical valves are made of metal. they're sturdy, however carry the danger of blood clots forming. Tissue valves could return from a pig, cow or human deceased donor. They usually eventually would like replacement. 

  • Ross procedure. This type of heart valve replacement uses your own pulmonary valve (autograft). It's not often used due to the availability of less complex, yet effective, options.

  • Transcatheter aortic valve replacement (TAVR). This is a less invasive approach to substitution a heart valve. TAVR involves substitution of the semilunar valve with a prosthetic valve through the Associate in Nursing artery in your leg or in a very tiny incision in your chest.
    In some cases, valves are often inserted through a tube into a tissue replacement valve that must get replaced (valve-in-valve procedure).
    TAVR is typically reserved for folks with severe semilunar valve pathology United Nations agency square measure at redoubled risk of complications from semilunar valve surgery. 

Preparing for your appointment

If you think that you or your kid incorporates a cardiac murmur, create an arrangement to ascertain your GP. Though most heart murmurs square measure harmless, it is a sensible plan to rule out any underlying heart issues that might be serious.

Because appointments may be transient, and since there is usually heaps to debate, it is a sensible plan to be ready for your appointment. Here's some data to assist you make preparations and recognize what to expect from your doctor.

  • Write down any symptoms you or your child is experiencing, including any that may seem unrelated to heart murmurs.

  • Write down key personal information, including a case history of heart murmurs, regular recurrence issues, heart defects, arteria malady, genetic disorders, stroke, high force per unit area or polygenic disorder, and any major stresses or recent life changes. 

  • Make a list of all medications, vitamins or supplements that you or your child is taking.

  • Take a family member or friend along, if doable. generally it is often tough to recollect all of the data provided to you throughout a rendezvous. somebody WHO comes alongside you'll keep in mind one thing that you just incomprehensible or forgot. 

  • Be prepared to discuss diet and exercise habits. If you or your child doesn't already follow a diet or exercise routine, be ready to talk to your doctor about any challenges you might face in getting started.

  • Write down questions to ask your doctor.

Your time with your doctor is limited, so preparing a list of questions can help you make the most of your time together. For heart murmurs, some basic questions to ask your doctor include:

  • What's the most likely cause of the heart murmur?

  • What are other possible causes for the heart murmur?

  • What kinds of tests are necessary?

  • What's the best treatment or follow-up care?

  • What are the alternatives to the primary approach that you're suggesting?

  • How should health conditions other than the heart murmur be managed?

  • Are there any dietary or exercise restrictions that I need to follow?

  • Should I see a specialist?

  • If surgery is necessary, which surgeon do you recommend?

  • Is there a generic alternative to the medicine you're prescribing?

  • Are there any brochures or other printed material that I can take home with me? What websites do you recommend visiting?

What to expect from your doctor

Your doctor is likely to ask you a number of questions. Being ready to answer them may reserve time to go over any points you want to spend more time on. Your doctor may ask:

  • When did you or your child first have symptoms?

  • Have the symptoms been continuous or occasional?

  • How severe are the symptoms?

  • What, if anything, seems to make your symptoms better?

  • Does anything make the symptoms worse?

  • Have you ever noticed a bluish discoloration of the skin?

  • Do you have shortness of breath? When does this happen?

  • Have you ever fainted?

  • Have you had chest pain?

  • Have you had swelling in your legs?

  • How do you feel when you exercise?

  • Have you ever used illicit drugs?

  • Have you ever had rheumatic fever?

  • Does anyone else in the family have a heart murmur or a heart valve problem?

General summary

  1. Exercise medication and weight loss are the most common treatments for heart murmurs If your doctor decides that you need to lose weight or increase your physical activity he or she may prescribe a diet and exercise plan Some people will be prescribed medications such as beta-blockers to treat their heart conditions Beta blockers prevent blood vessels from tightening These drugs are often used to treat high blood pressure chest pain (angina) caused by inadequate blood supply to the heart muscle and abnormal heart rhythms.
