Is Ankle Swelling Related to Heart Valve Disease?
Ankle swelling, known medically as peripheral oedema, is a common symptom with many potential causes, ranging from prolonged standing to underlying medical conditions. While often harmless, persistent swelling can sometimes be a clinical indicator of how well the heart is pumping.
In the context of heart valve disease, swelling typically occurs because the heart is under extra strain and cannot circulate blood efficiently. This article explains why this happens, what other signs to look for, and when you should seek professional advice to ensure your heart health is managed safely.

Why Valve Disease Can Cause Ankle Swelling
Ankle swelling can be a symptom of heart valve disease. When a heart valve is damaged – either becoming too narrow (stenosis) or leaky (regurgitation) – the heart must work harder to pump blood. This can lead to increased pressure in the veins, causing fluid to leak into the surrounding tissues, most commonly in the ankles and feet because of gravity.
When heart valves do not function correctly, they disrupt the one-way flow of blood. If the heart cannot keep up with the demand, blood ‘backs up’ in the circulatory system. This congestion increases the pressure in the small blood vessels (capillaries) in the lower limbs.
Under high pressure, watery fluid is pushed out of the vessels and into the skin and deeper tissues. This is why swelling often worsens throughout the day as gravity pulls fluid downward and may improve overnight when the legs are elevated. In clinical settings, this is often referred to as ‘pitting oedema’, where pressing a finger into the swollen area leaves a temporary indentation.
Other Common Symptoms of Heart Valve Disease
Beyond ankle swelling, heart valve disease often presents with breathlessness (dyspnoea), persistent fatigue, and heart palpitations. Some individuals may also experience chest pain or dizziness, particularly during physical activity. These symptoms occur because the body is not receiving an adequate supply of oxygenated blood due to the compromised valve function.
It is rare for ankle swelling to be the only sign of a heart valve problem. Most people will notice a cluster of symptoms that develop gradually over months or years:
- Breathlessness: This may start only during exercise but can progress to occurring at rest or when lying flat.
- Fatigue: Feeling unusually tired or weak, even after minor tasks like climbing stairs.
- Palpitations: A sensation of the heart fluttering, racing, or skipping a beat.
- Dizziness or Fainting: This happens if the brain does not receive enough blood flow, often triggered by sudden exertion.
- Chest Discomfort: A feeling of pressure or tightness, similar to angina.
Causes of Heart Valve Disease
Heart valve disease can be caused by age-related wear (calcification), congenital defects present from birth, or damage from previous infections like rheumatic fever or endocarditis. Other contributors include high blood pressure and previous heart attacks, which can stretch or scar the heart muscle and the valves attached to it.
Understanding the cause helps determine the management plan. The most frequent causes in the UK include:
- Ageing: Over time, calcium deposits can build up on the valves (especially the aortic valve), making them stiff and narrow (stenosis).
- Congenital Heart Disease: Some people are born with valves that are the wrong shape or size, such as a bicuspid aortic valve.
- Infections: Endocarditis is an infection of the heart’s inner lining that can permanently damage valve tissue.
- Rheumatic Fever: Though now rare in the UK, historical streptococcal infections can cause scarring of the valves that appears decades later.
- Heart Muscle Damage: Conditions like cardiomyopathy or damage from a heart attack can change the shape of the heart, causing the valves to leak.
Triggers for Worsening Symptoms
Symptoms of heart valve disease, including ankle swelling, can be triggered or worsened by a high-salt diet, excessive alcohol consumption, and physical overexertion. Respiratory infections and certain medications may also put additional strain on the heart, making existing valve issues more noticeable or severe.
If you have a known valve condition, certain factors can cause a ‘flare-up’ of fluid retention:
- Dietary Sodium: Salt causes the body to retain water, which increases the volume of blood the heart must pump.
- Inactivity: Lack of movement prevents the ‘calf pump’ (muscle contractions) from helping return blood to the heart, allowing fluid to pool.
- Decompensation: If the valve disease progresses to heart failure, the body’s ability to manage fluid balance significantly decreases.
- Pregnancy: The increased blood volume and physical pressure during pregnancy can unmask a previously silent valve condition.
Differentiating Heart Swelling from Other Causes
Direct Answer: Heart-related swelling usually affects both ankles equally and is often accompanied by breathlessness. In contrast, swelling caused by a blood clot (DVT) typically affects only one leg and may be painful or red. Other causes, like kidney disease or certain blood pressure medications (calcium channel blockers), can also cause bilateral swelling without primary heart issues.
| Feature | Heart Valve Disease / Heart Failure | DVT (Blood Clot) | Venous Insufficiency (Varicose Veins) |
| Symmetry | Usually both ankles/legs | Usually only one side | Often both, but one may be worse |
| Pain | Usually painless (just heavy) | Often painful, tender, or warm | Aching or ‘heavy’ feeling |
| Skin Changes | May be shiny or tight | Redness or discolouration | Skin may be itchy, brown, or dry |
| Accompanying Symptoms | Breathlessness, fatigue | Sudden calf pain | Visible bulging veins |
Conclusion
Ankle swelling can indeed be a sign of heart valve disease, particularly when it occurs alongside breathlessness or fatigue. This swelling is a result of the heart struggling to pump efficiently, leading to fluid backup in the lower limbs. While many cases of swelling are related to less serious factors like diet or inactivity, persistent oedema should always be monitored.
If you experience severe, sudden, or worsening symptoms, such as significant breathlessness or chest pain, call 999 immediately.
How do I know if my ankle swelling is serious?
Swelling is generally more concerning if it is persistent, worsens when lying down, or is accompanied by chest pain, dizziness, or a sudden inability to catch your breath.
Can heart valve disease cause swelling in only one ankle?
Heart-related swelling typically affects both legs symmetrically. Swelling in only one leg is more likely to be caused by an injury, infection (cellulitis), or a blood clot (DVT).
Does drinking water help reduce swollen ankles?
While staying hydrated is healthy, if the swelling is caused by heart valve disease, increasing fluid intake might worsen the retention. Consult a healthcare professional about fluid limits.
What is the fastest way to reduce heart-related swelling?
Resting with your legs elevated above the level of your heart and reducing salt intake can help, though medical treatments like diuretics (water tablets) are often required for cardiac causes.
Are there medications that cause ankle swelling?
Yes, some common medications, particularly calcium channel blockers used for high blood pressure, can cause ankle swelling as a side effect.
Why does the swelling get better overnight?
When you lie flat, gravity no longer pulls fluid toward your ankles, allowing the body to reabsorb the fluid into the bloodstream and eventually clear it through the kidneys.
