Heart valve disease happens when one or more heart valves do not open or close the right way. It can cause shortness of breath, chest discomfort, tiredness, dizziness, or swelling in the legs and feet, and early symptoms of heart valve disease may be mild at first. Heart valve disease is more common in older adults, but it can also affect younger people, including those born with a valve problem. Not everyone will have the same experience, and heart valve disease may stay stable for years or slowly worsen over time. Treatment depends on the cause and severity and may include regular checkups, medicines to ease symptoms, or a procedure or surgery to repair or replace the valve, and severe untreated cases can become life-threatening.
How many people live with Heart valve disease?
There is not one single recent worldwide count for all heart valve disease, because studies do not all include the same kinds of valve problems; one major type, called rheumatic heart disease, affected about 40.5 million people worldwide (Global Burden of Disease Study, 2019). In the United States, about 8 million people may be living with heart valve disease today, based on the widely used estimate that roughly 2.5% of people have it (Nkomo et al., 2006; U.S. Census Bureau, 2024).
Overview
Heart valve diseaseSymptoms
Heart valve disease can cause shortness of breath, tiredness, chest discomfort, dizziness, or fainting. Some people notice a fast or fluttering heartbeat, swollen ankles, or less stamina during everyday tasks, especially when walking uphill or climbing stairs.
Outlook and prognosis
Many people with heart valve disease do well for years with regular checkups, medicines, and sometimes a valve repair or replacement. Outlook depends on which valve is affected, how severe the leak or narrowing is, and whether heart function stays strong.
Causes and risk factors
Heart valve disease can result from aging, calcium buildup, infection, rheumatic fever, or a heart defect present at birth. Risk rises with high blood pressure, high cholesterol, smoking, diabetes, and past heart damage. Some medicines or radiation can raise risk.
Genetic influences
Genetics can matter in heart valve disease, especially when it runs in families or appears at a young age. Some gene changes raise risk, but many people with heart valve disease develop it mainly from aging, infection, or other health conditions.
Diagnosis
Heart valve disease is diagnosed with a medical history, physical exam, and listening for a murmur. An echocardiogram usually confirms the diagnosis. Doctors may also use ECG, chest X-ray, or cardiac MRI.
Treatment and drugs
Treatment for heart valve disease depends on which valve is affected and how severe the problem is. Many living with heart valve disease need regular checkups, medicines to ease symptoms or prevent complications, and sometimes a valve repair or replacement.
Symptoms
Heart valve disease can show up in everyday life as getting winded on stairs, feeling worn out after routine tasks, or noticing your heart seems to race or flutter. The early symptoms of heart valve disease can be easy to miss, especially when they come on gradually. Symptoms vary from person to person and can change over time.
You may feel winded during a walk, when climbing stairs, or sometimes even while resting. Some people also notice they need extra pillows at night because lying flat makes breathing harder.
Heart valve disease can make everyday tasks feel more tiring because the heart may have to work harder to move blood. Many people notice they cannot exercise or stay active as long as they used to.
Some people feel pressure, tightness, or aching in the chest, especially with activity. This should be checked promptly, particularly if it is new, severe, or comes with shortness of breath or fainting.
With heart valve disease, the heartbeat may feel fast, pounding, fluttering, or irregular. These episodes can come and go and may be more noticeable when you are resting quietly.
How people usually first notice Heart valve disease?
Heart valve disease often first shows up quietly: you may notice that everyday things like climbing stairs, walking uphill, or even lying flat suddenly leave you more short of breath than usual, or that your heart feels like it is fluttering, pounding, or skipping beats. Many people with heart valve disease also first notice unusual fatigue, chest discomfort, dizziness, swelling in the ankles or feet, or a new drop in exercise tolerance, while in some cases a doctor is the first to spot it by hearing a heart murmur, an unusual sound caused by blood moving abnormally through a valve. These early changes can be mild and easy to blame on aging, stress, or being out of shape, which is why new or worsening symptoms are worth getting checked.
Types of Heart valve disease
Heart valve disease can affect people in different ways depending on which valve is involved and how it is damaged. In medical terms, the main types of heart valve disease are stenosis, regurgitation, prolapse, and atresia. These types of heart valve disease can cause some overlapping symptoms, but the pattern and severity may differ from one person to another. Not everyone will experience every type.
Stenosis
This happens when a heart valve becomes stiff or narrowed, so blood has trouble moving forward. Many living with this type notice shortness of breath, chest discomfort, dizziness, or feeling unusually tired during walking or climbing stairs. Symptoms often build slowly, especially as the narrowing becomes more severe.
Regurgitation
This type means the valve does not close tightly, so some blood leaks backward with each heartbeat. For many, this can mean breathlessness, tiredness, a pounding heartbeat, or ankle and foot swelling as the heart works harder. Some people have few symptoms at first, while others notice them more during activity or when lying flat.
Prolapse
In valve prolapse, part of the valve bulges backward when the heart squeezes, most often affecting the mitral valve. Some may find they have palpitations, brief chest pain, lightheadedness, or fatigue, while others feel nothing at all. Symptoms do not always match how mild or severe the prolapse looks on a heart scan.
Atresia
This is a rare form present from birth in which a valve does not form properly, so blood cannot pass through it in the usual way. Symptoms usually appear early in life and can include bluish skin, fast breathing, poor feeding, or low energy rather than the gradual symptoms seen in adult valve disease. Less frequent, but still important, are severe cases that need urgent treatment soon after birth.
Can I slow down the onset of symptoms?
Usually not by a lot: for most heart valve disease, there is no proven lifestyle change or medicine that can stop the valve problem from starting, especially when it is linked to aging, a valve difference present from birth, or past infection. Still, heart-healthy habits like keeping blood pressure, cholesterol, blood sugar, and weight in a healthy range, not smoking, staying active, and treating sleep apnea if present may reduce strain on the heart and may help symptoms show up later, but that is not the same as preventing valve disease itself. If you already have a valve problem or a heart murmur, regular follow-up with heart scans and getting repair or replacement at the right time is the most proven medical step to avoid complications, and it can help many living with heart valve disease stay well longer without promising a specific outcome.
What genetics can tell you about symptoms
Genetics can sometimes help explain why heart valve disease shows up earlier in life, affects certain valves, or runs in families, especially in inherited conditions such as a bicuspid aortic valve or disorders that affect connective tissue. In these cases, genetic differences may influence which symptoms appear, how quickly valve problems worsen, and whether people develop shortness of breath, chest discomfort, fatigue, or fainting sooner than expected. Still, many people with heart valve disease develop it mainly from aging, calcium buildup, past infection, or other heart conditions, so genetics is only one part of the picture.
Causes and risk factors
Heart valve disease often develops when a valve wears down with age or is damaged by rheumatic fever, a heart infection, or a past heart attack. Some people are born with a valve that did not form in the usual way, and a family history of valve problems can also raise risk. High blood pressure, high cholesterol, diabetes, kidney disease, and past radiation to the chest can make valve damage more likely. It is rarely just one factor, and the mix matters. Smoking, carrying excess weight, and not treating other heart conditions can add to the risk factors for heart valve disease.
What are the most common causes or risk factors?
The most common causes of heart valve disease are age-related wear and tear with calcium buildup on the valves, and being born with a valve that did not form normally, which can sometimes run in families. Other well-known causes include damage after rheumatic fever, which can happen after an untreated strep infection, and infections that reach and injure a heart valve. Risk is also higher in older adults and in people with high blood pressure, high cholesterol, smoking, kidney disease, or a history of heart attack or heart failure.
Environmental and biological risk factors
Heart valve disease becomes more likely when valve tissue is damaged, stiffened, scarred, or stretched over time. Doctors often group risks into internal (biological) and external (environmental). These are some of the main risk factors for heart valve disease, especially in older adults and people with certain infections, heart conditions, or past chest treatments. Having one risk factor does not mean valve disease will definitely develop.
As people age, heart valves can gradually thicken and collect calcium, which makes them open less easily or close less tightly. This is one of the most common biological reasons heart valve disease appears later in life.
Some people are born with a valve that has an unusual shape or structure, so it wears out faster over the years. This can raise the chance of heart valve disease at a younger age than usual.
A past episode of rheumatic fever can leave scarring on the valves, sometimes years after the original illness. This scarring may slowly lead to narrowing or leaking of a valve.
A serious infection on a heart valve can damage the tissue directly and leave it rough or weakened. After this kind of infection, the risk of future heart valve disease is higher.
Genetic risk factors
Some forms of heart valve disease run in families or happen as part of inherited syndromes that affect how the heart or nearby tissues develop. The strongest genetic links are seen with bicuspid aortic valve and with inherited conditions such as Marfan syndrome, Loeys-Dietz syndrome, and some forms of Ehlers-Danlos syndrome. Some risk factors are inherited through our genes. Knowing the genetic risk factors for heart valve disease can help families decide when heart checks may be useful.
Family history: Heart valve disease can be more likely if a close relative has had a valve problem, especially at a younger age. This does not mean you will definitely develop the same issue, but it can raise inherited risk.
Bicuspid aortic valve: Some people are born with an aortic valve that has 2 flaps instead of 3, and this often runs in families. Over time, that valve can become narrowed or leaky, making it one of the clearest inherited causes of heart valve disease.
Marfan syndrome: This inherited condition affects the body's connective tissues, which help support the heart and blood vessels. Many living with Marfan syndrome have a higher chance of aortic valve leakage or mitral valve prolapse, where the valve bows backward.
Loeys-Dietz syndrome: This genetic condition can weaken tissues in the heart and major blood vessels from an early age. It may raise the risk of valve leakage, especially involving the aortic or mitral valve.
Ehlers-Danlos syndrome: Some inherited forms of Ehlers-Danlos syndrome affect connective tissue strength throughout the body. In some people, this can increase the chance of floppy or leaky heart valves, although the pattern can vary by subtype.
Turner syndrome: People with Turner syndrome have a higher chance of being born with valve differences, especially involving the aortic valve. This can lead to valve narrowing or leakage and may overlap with bicuspid aortic valve.
Noonan syndrome: Noonan syndrome is an inherited condition that can affect how the heart forms before birth. It is more often linked to pulmonary valve narrowing, but other valve problems can also occur.
Lifestyle risk factors
Some forms of heart valve disease are age-related or follow other heart conditions, but lifestyle habits can still raise the chance of valve damage or make symptoms and complications worse. In practice, how lifestyle affects heart valve disease often comes through blood pressure, cholesterol, body weight, heart strain, and behaviors that increase the risk of heart infection. The most important lifestyle risk factors are smoking, poor diet, physical inactivity, excess body weight, harmful alcohol or drug use, and poor treatment adherence for related conditions.
Smoking damages blood vessels, promotes inflammation, and increases the risk of coronary artery disease and aortic valve calcification. It can also worsen breathlessness and reduce exercise tolerance in people who already have valve disease.
A diet high in salt, saturated fat, and ultra-processed foods can raise blood pressure, cholesterol, and fluid retention, which increases strain on diseased heart valves. Over time, this can worsen symptoms such as swelling, shortness of breath, and reduced stamina.
Too little physical activity contributes to poor cardiovascular fitness, weight gain, and higher blood pressure, all of which can worsen the workload on the heart. Regular, appropriate exercise may help preserve endurance and symptom control, depending on the severity of the valve problem.
Carrying excess body weight makes the heart work harder and can intensify symptoms in people with valve disease. Obesity is also linked to high blood pressure, sleep apnea, and diabetes, which may accelerate decline in heart function.
Risk prevention
Heart valve disease is not always fully preventable, but many cases can be delayed or the risk can be lowered by protecting heart health and treating infections early. For many, this means paying attention to blood pressure, dental care, and symptoms that could point to valve trouble before damage builds up. Prevention works best when combined with regular check-ups.
High blood pressure can strain the heart and gradually damage its valves over time. Keeping blood pressure in a healthy range with food choices, movement, weight management, and medication when needed can lower the risk of heart valve disease.
Some valve damage starts after infections such as strep throat or infections in the bloodstream. Prompt treatment of sore throats when a bacterial infection is suspected, good wound care, and safer injection practices can help protect the valves.
Poor oral health can allow bacteria from the mouth to enter the bloodstream and reach the heart valves, especially in people already at risk. Regular brushing, flossing, and dental visits are a simple but important way to reduce this risk.
Smoking, high cholesterol, diabetes, and low physical activity can all raise the chance of heart and valve problems. Healthy routines are like safety belts: simple, everyday habits that offer protection.
Can you prevent Heart valve disease?
Heart valve disease cannot always be prevented, especially if someone is born with a valve problem or if a valve becomes stiff or leaky with age. Still, some risks can be lowered by getting strep throat treated promptly, not smoking, and taking good care of blood pressure, cholesterol, and diabetes. Regular medical and dental care can also help lower the chance of some valve problems and catch changes early, but they cannot guarantee prevention.
Transmission
Heart valve disease is not contagious, so it cannot be passed from one person to another through touching, kissing, coughing, sex, blood, food, or shared spaces. Many living with heart valve disease develop it over time, and being near someone with the condition does not put you at risk.
If you are wondering how heart valve disease is inherited, most cases are not passed down directly in families. Still, some valve problems are present at birth or are linked to inherited conditions, so a family history can sometimes matter and may prompt a doctor to look more closely at close relatives.
When to test your genes
For most people with heart valve disease, genetic testing is not routine. It becomes worth discussing if valve disease appears unusually early, runs in your family, or occurs with an enlarged aorta or features of connective tissue conditions such as Marfan syndrome, because results can guide surveillance and family screening.
Diagnosis
For many, the first step comes when everyday activities start feeling harder. Heart valve disease is often diagnosed after symptoms such as shortness of breath, chest discomfort, fatigue, dizziness, or swelling lead to a medical visit, although some people learn about it after a murmur is heard at a routine exam. The diagnosis of heart valve disease usually combines a physical exam with heart imaging and, when needed, other tests to show how well the valve opens and closes.
Doctors usually begin by asking about symptoms, when they started, and whether they happen with exercise, lying flat, or daily activities. A detailed family and health history can help uncover past infections, heart problems, or other conditions that may affect the valves.
A clinician listens to the heart for a murmur, which is an extra or unusual sound caused by blood moving across a narrowed or leaky valve. They also look for signs such as ankle swelling, lung crackles, blue-tinged lips, or an irregular heartbeat.
This ultrasound of the heart is the main test used for how heart valve disease is diagnosed. It shows the valve structure, how blood flows through the heart, and whether a valve is narrowed, leaking, or not opening properly.
An electrocardiogram, also called an ECG or EKG, records the heart's electrical activity. It can show rhythm problems or signs that the heart muscle is under strain from a valve problem.
How is Heart valve disease diagnosed?
Heart valve disease is usually diagnosed after a doctor asks about symptoms, listens to the heart, and checks for signs such as a heart murmur, which is an extra or unusual sound. The main test is an echocardiogram, which is an ultrasound scan of the heart that shows how the valves open and close and whether blood is leaking backward or having trouble moving forward; doctors may also use a heart tracing, a chest X-ray, an exercise test, or other heart scans to see how serious it is. Genetic testing is not usually needed, but it may be considered if valve problems seem to run in the family or are part of an inherited condition.
Stages of Heart valve disease
Heart valve disease does not have defined progression stages. That is because it is usually described by which valve is affected and how severe the problem is, rather than by one fixed step-by-step timeline that everyone follows. Often the process begins when you notice changes in daily life, such as getting short of breath on stairs, feeling unusually tired, or hearing that you have a heart murmur during a routine exam. Doctors usually diagnose and monitor heart valve disease with a physical exam, an ultrasound of the heart called an echocardiogram, and sometimes other heart tests, especially if early symptoms of heart valve disease are subtle or come on gradually.
Outlook and prognosis
The outlook for heart valve disease varies widely depending on which valve is affected, how severe the damage is, how quickly it progresses, and whether symptoms or heart dysfunction develop. Mild valve disease may remain stable for years with monitoring, while severe untreated disease can lead to heart failure, atrial fibrillation, stroke, pulmonary hypertension, recurrent hospitalizations, and reduced quality of life. Prognosis is generally much better when the condition is recognized early and managed appropriately with medicines, regular imaging, and valve repair or replacement when indicated. Many people do very well after timely intervention, with substantial symptom relief and survival that can approach that of people without major valve disease in some settings. Mortality rises when severe valve disease is left untreated, especially in symptomatic aortic stenosis or advanced mitral regurgitation, where the risk of death increases significantly once heart damage or heart failure develops. Age, other heart conditions, kidney disease, lung disease, and frailty also strongly influence long-term outcome.
Long-term effects
Heart valve disease can affect how easily blood moves through the heart, and over time that may change day-to-day stamina, breathing, and overall heart function. Some people live for years with mild problems, while others notice walking uphill, carrying groceries, or lying flat in bed becomes harder. Understanding long-term patterns can guide treatment choices. The long-term effects of heart valve disease depend on which valve is involved, how severe the problem is, and whether it is treated.
When a damaged valve makes the heart work harder for a long time, the heart muscle can weaken or become stiff. This can lead to heart failure, with ongoing shortness of breath, swelling in the legs, and fatigue during everyday activity.
Heart valve disease can stretch the upper chambers of the heart and raise the risk of irregular heartbeats, especially atrial fibrillation. Over time, this may cause palpitations, reduced exercise tolerance, or spells of lightheadedness.
Some rhythm problems linked to heart valve disease can allow blood clots to form in the heart. If a clot travels to the brain, it can cause a stroke, which is one reason doctors watch closely for rhythm changes.
Fluid can back up into the lungs when a valve problem becomes more advanced. Many living with heart valve disease notice breathlessness with activity at first, and later some may find it harder to breathe when resting or sleeping flat.
How is it to live with Heart valve disease?
Living with heart valve disease can feel unpredictable: some days you may notice almost nothing, while on others shortness of breath, fatigue, chest discomfort, dizziness, or a pounding heartbeat can make stairs, exercise, work, or even routine chores feel harder than they should. For many people, daily life also includes medications, medical visits, and paying close attention to symptoms, and if the valve problem becomes more severe, energy levels and independence can be affected. It often touches the people around you too, since family members may take on extra practical help or worry about changes in stamina and future treatment, but with regular care and the right treatment plan, many people with heart valve disease are able to stay active and keep a good quality of life.
Treatment and drugs
Treatment for heart valve disease depends on which valve is affected, how severe the problem is, and whether it is causing symptoms such as shortness of breath, chest discomfort, or fatigue during everyday activities like climbing stairs or walking uphill. Some people with heart valve disease mainly need regular checkups and heart scans, while others benefit from medicines to ease fluid buildup, lower blood pressure, control heart rhythm, or reduce strain on the heart; these drugs usually help symptoms but do not fix a damaged valve. Doctors sometimes recommend a combination of lifestyle changes and drugs. If the valve is badly narrowed or leaking, the main treatment may be a procedure or surgery to repair or replace the valve, sometimes through a catheter and sometimes with open-heart surgery. Not every treatment works the same way for every person, so the best treatment for heart valve disease is based on your symptoms, overall health, and how the valve is working over time.
Can you cure Heart valve disease?
Heart valve disease usually cannot be cured with medicine alone, but many people can be treated very effectively. Medicines can help ease symptoms and lower strain on the heart, and some people need a procedure or surgery to repair or replace the damaged valve. The best treatment depends on which valve is affected and how severe the problem is.
Non-drug treatment
Heart valve disease can affect day-to-day life in quiet but important ways, such as getting winded on stairs, feeling unusually tired, or noticing swelling by the end of the day. Treatment is not always just about medicine; many people also benefit from monitoring, lifestyle changes, rehabilitation, and sometimes procedures to repair or replace a damaged valve. Managing this condition often means matching the approach to how severe the valve problem is, which valve is affected, and whether symptoms are present. Some people do well with careful follow-up for years, while others need a procedure sooner to protect the heart.
Checkups and heart scans help track whether heart valve disease is staying stable or starting to strain the heart. This is especially important because symptoms can change slowly, and some people feel well even as the valve problem worsens.
Safe, tailored activity can help maintain strength, stamina, and confidence in daily life. Ask your doctor which non-drug options might be most effective if you are unsure about exercise for heart valve disease, since limits depend on the type and severity of the valve problem.
Structured programs, like cardiac rehabilitation, can help people rebuild endurance and recover safely after a valve procedure or surgery. These programs also teach pacing, symptom awareness, and heart-healthy habits.
Lower-salt meals and balanced eating patterns can help if heart valve disease is causing fluid buildup or added strain on the heart. Reaching and maintaining a healthy weight may also make breathing and activity feel easier.
Your genes may have an impact on how drugs work for you
For many living with heart valve disease, medicines are often used to ease strain on the heart, control blood pressure or fluid buildup, or prevent blood clots after a valve procedure, and your genes can sometimes affect how strongly your body reacts to these treatments. A well-known example is the blood thinner warfarin: some people’s bodies break it down differently, so a usual dose may be too much or too little, which can raise the risk of bleeding or clotting until the dose is adjusted. This kind of gene-based difference in medicine response is part of pharmacogenomics, and while it is not important for every heart valve medicine, it can matter in some situations.
Pharmacological treatments
Heart valve disease often causes symptoms because the heart has to work harder or because fluid backs up into the lungs or legs. Medicines cannot usually repair a damaged valve, but they can ease symptoms, lower strain on the heart, and reduce the risk of problems such as irregular heartbeat, blood clots, or heart failure. Medication can feel like a big step, but treatment is often tailored to the specific valve problem, how severe it is, and whether symptoms are getting in the way of daily life. In people with early symptoms of heart valve disease, drugs may help for a time, while others may still need a valve procedure or surgery later on.
Diuretics such as furosemide, bumetanide, and torsemide help the body get rid of extra salt and water. This can ease shortness of breath and swelling in the feet, ankles, or legs when fluid is building up.
Medicines such as lisinopril, enalapril, losartan, and valsartan may reduce the heart’s workload, especially when high blood pressure is making valve disease harder to manage. Some people with leaking valves may benefit from these drugs more than people with narrowed valves.
Drugs such as metoprolol, carvedilol, and atenolol can slow the heart rate and help it pump more efficiently. They are often used when heart valve disease is linked with palpitations, atrial fibrillation, or heart failure symptoms.
Anticoagulants such as warfarin, apixaban, rivaroxaban, dabigatran, and edoxaban help prevent blood clots in certain situations. They are commonly used if someone has atrial fibrillation, and warfarin is especially important after placement of a mechanical heart valve.
Genetic influences
When heart valve disease shows up in several relatives, it can raise questions about whether the pattern is inherited. In some families, genes can affect how a heart valve forms before birth or how strong the valve tissue stays over time, which may increase the chance of problems such as narrowing or leaking. Family history is one of the strongest clues to a genetic influence. This is especially true when heart valve disease appears at a younger age, runs through multiple generations, or is linked with inherited conditions that affect connective tissue, the material that helps support the valves. Still, not all heart valve disease is genetic, and many people develop it mainly because of aging, calcium buildup, infection, or other heart conditions. If there is a strong family pattern, doctors may suggest checking close relatives and, in some cases, discussing whether genetic counseling would help clarify the risk.
Is Heart valve disease genetic?
Genetics can matter in heart valve disease, especially when it runs in families or appears at a young age. Some gene changes raise risk, but many people with heart valve disease develop it mainly from aging, infection, or other health conditions.
Having a genetic risk is not necessarily a diagnosis
Changes in genes, often called genetic variants, are a normal part of being human and are common in the general population. Most of these variants do not directly affect health and simply reflect natural differences among people. For many genes, having a variant that is linked to a condition suggests a possible association rather than a certain diagnosis, especially when several genes and environmental factors are involved. Still, in some cases, one well-understood variant in a particular gene is enough to confirm a diagnosis.
Pharmacogenetics—how genetics influence drug effects
For many living with heart valve disease, treatment is not one-size-fits-all, because the genes linked to the valve problem can help guide how closely doctors monitor it and when repair or replacement may be safest. Some inherited conditions that affect connective tissue or heart development can make valve problems worsen earlier or raise the chance of related issues in the aorta, so family members may also be offered screening. When medication is part of care, genetics can sometimes affect how your body handles certain drugs, especially blood thinners used after valve surgery or with a mechanical valve, which may influence the starting dose and the risk of bleeding. Not every difference in response is genetic, but age, kidney function, other medicines, and the type of valve problem also matter. This is one reason doctors may use genetic testing in selected cases to understand how genetics affect treatment for heart valve disease and to plan care more precisely. Even so, most people with heart valve disease are treated using a mix of symptoms, scans, family history, and sometimes genetic results rather than genes alone.
Interactions with other conditions
Day-to-day, heart valve disease can make other health problems feel more noticeable, especially if you already live with heart failure, high blood pressure, or an irregular heartbeat such as atrial fibrillation. Someone might notice they get much more short of breath walking up stairs when fluid buildup, a chest infection, or anemia happens at the same time. Heart valve disease can also raise the risk of infections affecting the heart valves, called infective endocarditis, particularly in some people with damaged or artificial valves. Kidney disease and lung disease may add strain as well, because the heart has to work harder when the body is holding extra fluid or oxygen levels are lower than usual. Diabetes and coronary artery disease often travel alongside heart valve disease, which can complicate treatment decisions and recovery after procedures. Talk with your doctor about how your conditions may influence each other, especially if you notice new swelling, dizziness, chest discomfort, or worsening fatigue.
How genes can cause diseases
Humans have more than 20,000 genes, each carrying out one or a few specific functions in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the body's cells from beginning to multiply uncontrollably and developing into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call these hotspots "Genetic Variations" or "Variants" in short. In many cases, studies have been able to show that having the genetic letter "G" in the position makes you healthy, but having the letter "A" in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
What other conditions can cause similar symptoms to Heart valve disease?
Other heart and lung problems can cause symptoms much like heart valve disease, especially shortness of breath, tiredness, chest pain, dizziness, or a racing heartbeat. Common examples include heart failure, blocked heart arteries, an irregular heartbeat such as atrial fibrillation, and a weakened or thickened heart muscle. Lung conditions like asthma or chronic obstructive pulmonary disease, as well as low red blood cell levels called anemia, can also look similar, so tests are often needed to tell the cause apart.
History
Long before scans and heart ultrasounds existed, doctors could still hear that something was not quite right in the chest. Throughout history, people have described breathlessness, tiring easily, chest discomfort, swelling in the legs, and a fluttering heartbeat that came on during ordinary tasks like climbing stairs or walking to the market. What we now group under heart valve disease was once recognized mainly through these day-to-day problems and through careful listening with the ear, and later with the stethoscope.
In the 1800s and early 1900s, physicians became better at linking certain heart sounds, called murmurs, with damage or narrowing in specific valves. Autopsies helped confirm what had been suspected during life: some valves had become stiff and tight, while others no longer closed properly and leaked. Over time, doctors also learned that heart valve disease could develop for different reasons, including age-related wear, infection, or after illnesses such as rheumatic fever, which was once a much more common cause in children and young adults.
As medical science evolved, the biggest change came when doctors could see the valves working in a living person rather than guessing from symptoms alone. Chest X-rays, then ultrasound of the heart, made it much easier to spot early symptoms of heart valve disease and to judge how severe it was. This shifted care from simply easing symptoms to monitoring the condition closely and deciding when repair or replacement might help.
Treatment has changed just as dramatically. Early surgery on heart valves was limited and risky, but advances in anesthesia, heart-lung machines, artificial valves, and less invasive catheter-based procedures have made treatment safer and more effective for many living with heart valve disease. In recent decades, awareness has grown that some people may have valve problems for years before they feel unwell, which is why checkups, imaging, and timely follow-up now play such an important role. Today, heart valve disease is understood far better than it once was, and many people can live longer and more active lives with modern care.
