Understanding Blood Clots: Formation and Function

Blood clots are aggregations of cells and proteins that form in the bloodstream. While clotting is a normal and essential process that helps stop bleeding when we’re injured, problematic clots can develop and pose serious health risks. But how exactly do blood clots form, and what purpose do they serve in the body?

Under normal circumstances, blood clots form as part of the body’s natural healing process. When a blood vessel is damaged, platelets rush to the site and begin to stick together. This triggers a cascade of clotting factors that ultimately result in the formation of fibrin, a protein that creates a mesh-like structure to trap more platelets and red blood cells. This clot acts as a plug to stop blood loss while the damaged vessel heals.

In most cases, the body gradually breaks down and absorbs the clot as healing progresses. However, clots can become dangerous when they form inappropriately or fail to dissolve properly. These problematic clots may partially or completely block blood flow, leading to a range of potentially life-threatening complications.

Recognizing the Warning Signs: Key Blood Clot Symptoms

Identifying the symptoms of a blood clot is crucial for early detection and treatment. The specific signs can vary depending on the location of the clot in the body. What are some of the most common symptoms to watch out for?

• Swelling in a limb, often accompanied by pain or tenderness
• Skin discoloration, appearing reddish or bluish
• Warmth in the affected area
• Sudden, severe chest pain
• Shortness of breath or difficulty breathing
• Rapid heartbeat
• Coughing, sometimes with blood-tinged sputum
• Leg pain or cramping, especially in the calf

It’s important to note that some blood clots may not cause any noticeable symptoms, particularly in the early stages. This is why understanding risk factors and maintaining awareness is crucial.

Deep Vein Thrombosis (DVT): A Hidden Threat

Deep vein thrombosis is a particularly concerning type of blood clot that forms in the deep veins, typically in the legs. How can you recognize the signs of DVT?

Common symptoms of DVT include swelling in one leg, pain or tenderness in the affected area, and skin that feels warm to the touch. The skin over the clot may also appear reddish or bluish. In some cases, you might experience a feeling of heaviness in the affected limb.

DVT is especially dangerous because it can lead to a pulmonary embolism if a piece of the clot breaks off and travels to the lungs. This is why prompt medical attention is crucial if you suspect you might have DVT.

The Silent Killer: Pulmonary Embolism Symptoms

A pulmonary embolism (PE) occurs when a blood clot travels to the lungs and blocks a pulmonary artery. This condition can be life-threatening and requires immediate medical intervention. What are the telltale signs of a pulmonary embolism?

• Sudden shortness of breath
• Chest pain that may worsen with deep breathing
• Rapid heartbeat
• Coughing, potentially with blood-tinged sputum
• Lightheadedness or fainting
• Excessive sweating
• Anxiety or sense of impending doom

If you experience any combination of these symptoms, especially if they come on suddenly, it’s crucial to seek emergency medical care immediately. Pulmonary embolisms can be fatal if not treated promptly.

Risk Factors: Who’s Most Likely to Develop Blood Clots?

Understanding the risk factors for blood clots can help you assess your personal risk and take appropriate preventive measures. Which factors increase the likelihood of developing a blood clot?

1. Age: Being over 60 increases clot risk
2. Obesity: Excess weight puts pressure on veins
3. Prolonged immobility: Long periods of sitting or bed rest
4. Recent surgery or injury
5. Pregnancy and postpartum period
6. Hormonal birth control or hormone replacement therapy
7. Smoking
8. Certain medical conditions: Cancer, heart disease, diabetes
9. Family history of blood clots
10. Previous history of blood clots

While some risk factors, like age and family history, can’t be changed, others can be modified through lifestyle changes. Maintaining a healthy weight, staying active, and avoiding prolonged periods of immobility can significantly reduce your risk of developing blood clots.

Diagnosing Blood Clots: Medical Tests and Procedures

When a blood clot is suspected, prompt and accurate diagnosis is crucial. How do medical professionals detect and confirm the presence of a blood clot?

The diagnostic process typically begins with a physical examination and a review of your medical history and symptoms. Based on this initial assessment, your doctor may recommend one or more of the following tests:

• D-dimer blood test: Measures a substance released when blood clots break down
• Ultrasound: Uses sound waves to visualize blood flow and detect clots
• CT scan: Provides detailed images of blood vessels and potential clots
• Venography: Uses contrast dye and X-rays to visualize veins
• MRI: Creates detailed images of blood vessels and surrounding tissues
• V/Q scan: Assesses blood flow and air flow in the lungs

The choice of diagnostic test often depends on the suspected location of the clot and the patient’s overall health status. In some cases, multiple tests may be necessary to confirm a diagnosis and determine the extent of the clot.

The Importance of Timely Diagnosis

Early detection of blood clots can significantly improve treatment outcomes and reduce the risk of serious complications. This is why it’s crucial to seek medical attention promptly if you experience symptoms or have concerns about blood clots, especially if you have known risk factors.

Treatment Options: Breaking Down and Preventing Clots

Once a blood clot is diagnosed, treatment typically focuses on three main goals: breaking down existing clots, preventing new clots from forming, and reducing the risk of complications. What are the primary treatment options available for blood clots?

1. Anticoagulants (blood thinners): Medications that prevent blood from clotting as easily
2. Thrombolytics: Powerful drugs that can quickly dissolve large clots
3. Catheter-directed thrombolysis: A minimally invasive procedure to deliver clot-busting drugs directly to the clot
4. Thrombectomy: Surgical removal of the clot
5. Inferior vena cava (IVC) filter: A device implanted to catch blood clots before they reach the lungs
6. Compression stockings: Help improve blood flow in the legs

The specific treatment plan will depend on various factors, including the location and size of the clot, the patient’s overall health, and the presence of any underlying conditions. In many cases, a combination of treatments may be used to achieve the best outcomes.

Long-term Management and Prevention

For many patients, blood clot treatment extends beyond the initial intervention. Long-term management often involves ongoing use of anticoagulants and lifestyle modifications to reduce the risk of future clots. This may include:

• Regular exercise to improve circulation
• Maintaining a healthy weight
• Quitting smoking
• Avoiding prolonged periods of immobility
• Using compression stockings as recommended
• Following a heart-healthy diet

Your healthcare provider will work with you to develop a personalized prevention plan based on your individual risk factors and medical history.

When to Seek Emergency Care: Red Flags for Blood Clots

Given the potential severity of blood clots, it’s crucial to know when to seek immediate medical attention. Which symptoms should prompt you to go to the emergency room or call for an ambulance?

• Sudden, severe shortness of breath
• Chest pain, especially if it worsens with deep breaths
• Coughing up blood
• Rapid or irregular heartbeat
• Fainting or loss of consciousness
• Sudden weakness or numbness, especially on one side of the body
• Severe headache with no known cause
• Sudden vision changes
• Difficulty speaking or understanding speech

These symptoms could indicate a pulmonary embolism, heart attack, or stroke – all of which are medical emergencies requiring immediate treatment. Remember, when it comes to potential blood clots, it’s always better to err on the side of caution and seek professional medical evaluation.

Living with Blood Clots: Long-term Outlook and Quality of Life

For many individuals who have experienced a blood clot, life doesn’t simply return to normal after treatment. How does a blood clot diagnosis impact long-term health and quality of life?

The long-term outlook for blood clot survivors can vary significantly depending on factors such as the location and severity of the clot, how quickly treatment was initiated, and the presence of any underlying health conditions. Many people recover fully with proper treatment and ongoing management. However, some may experience lasting effects, such as:

• Post-thrombotic syndrome: Ongoing swelling, pain, and skin changes in the affected limb
• Chronic thromboembolic pulmonary hypertension: High blood pressure in the lungs due to residual clots
• Anxiety or depression related to the fear of recurrence
• Lifestyle adjustments to accommodate ongoing anticoagulant therapy

Despite these challenges, many blood clot survivors lead full and active lives. Working closely with healthcare providers, adhering to treatment plans, and making necessary lifestyle modifications can significantly improve long-term outcomes and quality of life.

The Importance of Support and Education

Coping with the aftermath of a blood clot can be challenging, both physically and emotionally. Support groups and educational resources can play a crucial role in helping patients navigate their recovery and ongoing management. These resources can provide valuable information, emotional support, and practical tips for living with the effects of blood clots.

Additionally, staying informed about the latest developments in blood clot prevention and treatment can empower patients to take an active role in their health management. Regular check-ups and open communication with healthcare providers are essential for monitoring progress and adjusting treatment plans as needed.

4 Blood Clot Symptoms Not To Ignore

Medically Reviewed by James Beckerman, MD, FACC on November 18, 2022

It’s a clump of cells and protein in your blood. A clot helps slow bleeding when you’re injured. It usually dissolves as you heal. But if it doesn’t, or if it forms when it’s not needed, it can clog up or completely block a blood vessel.

An unexpected clot can lead to serious problems and even death. In an artery, it can give you a heart attack or a stroke. If it happens in a vein, you can feel pain and swelling. A clot deep inside your body is called a deep vein thrombosis (DVT). One in your lungs is a pulmonary embolism (PE). They’re both medical emergencies.

You can get a blood clot if you break a bone or pull a muscle badly. But sometimes you may not know why it happened or even realize you have one. There are clues though. Your odds of a clot are higher if you:

• Are recovering from surgery or had to sit for many hours on a flight or in a wheelchair
• Are overweight or obese
• Have diabetes or high cholesterol
• Are over 60

When a clot slows or stops the flow of blood, it can build up in the vessel and make it swell. If it happens in your lower leg or calf, it’s often a sign of DVT. But you also can have a clot in your arms or belly. Even after it goes away, one in three people still have swelling and sometimes pain and sores from damage to the blood vessel.

If a clot plugs up veins in your arms or legs, they may look bluish or reddish. Your skin also might stay discolored from the damage to blood vessels afterward. A PE in your lung could make your skin pale, bluish, and clammy.

Sudden, intense chest pain could mean the clot has broken off and caused a PE. Or it could be a sign that a clot in your artery gave you a heart attack. If so, you also might feel pain in your arm, especially on the left. A clot often hurts where it’s located, like in your lower leg, stomach, or under your throat.

This is a serious symptom. It could be a sign that you have a clot in your lung or your heart. Your heart might also race, or you may feel sweaty or faint.

A clot can give you different symptoms based on where it is. A PE can give you a fast pulse, chest pain, bloody cough, and shortness of breath. Get to the hospital right away. You also might have no signs.

This can feel similar to a clot in the lung. But if it’s a heart attack, you also might feel nausea and lightheadedness along with the chest pain. Either way, call 911 or get to a hospital right away.

Pressure builds when blood can’t flow normally. A severe blockage sometimes can lead to a stroke. Without oxygen from the blood, your brain cells start to die in minutes. A clot in your brain can cause headaches, confusion, seizures, speech problems, and weakness, sometimes on just one side of the body.

Often, you have no symptoms at all. Blocked veins in the stomach or esophagus, a tube that connects it to your throat, can rip and leak blood. That can hurt a lot. You may poop or vomit blood, and your stool might look black and smell unusually bad.

Also called renal vein thrombosis, these clots usually grow slowly and mostly in adults. You probably won’t have symptoms unless a piece breaks off and lodges in your lung. Rarely, especially in children, it can happen fast and cause nausea, fever, and vomiting. You also might have blood in your pee and go less often. 

See your doctor or go to the emergency room right away. A clot can be deadly, and you won’t know for sure you have it until you get checked. Your doctor may give you a clot-busting drug or surgically thread a thin tube to the site of the clot to dissolve it. 

You can act to lower your odds of a clot. First, keep a healthy weight, eat right, and exercise. Also:

• Don’t sit or stay still for long, especially after a long trip or surgery.
• If you’re a desk jockey, get up and move at least every couple of hours. Flex your legs, feet, and toes in your chair.
• Check if tight-fitting compression socks or garments can help your blood flow.
• Ask your doctor if you might need to take clot-fighting drugs called anticoagulants.

What does a blood clot feel like?

A blood clot may cause swelling or pain in a leg, arm, or another area, but it doesn’t always. Here, learn how to recognize signs of a blood clot and what you should do if you experience them.

Blood clots are a serious issue, as they can be life threatening. Also called thrombosis, this condition occurs when clots form in the vessels that contain blood, preventing it from flowing effectively.

Blood clots can form in the veins or arteries. When a blood clot occurs in one of your veins, it’s called venous thromboembolism (VTE).

According to the Centers for Disease Control and Prevention (CDC), an estimated 900,000 people in the United States are affected by blood clots each year. An estimated 60,000 to 100,000 people die from this condition annually. Males are at a higher risk of getting both a first-time and a recurring blood clot than females.

If you’re even slightly concerned you might have a blood clot, call your doctor right away. Symptoms of blood clots can vary. It’s also possible to have a blood clot with no symptoms.

Read on to learn about some of the symptoms that may indicate a blood clot.

A blood clot that shows up in one of the major veins in your body is called deep vein thrombosis (DVT). They’re most common in the legs or the hip region.

A blood clot could break loose and travel to your lungs. This leads to a serious and potentially fatal condition known as pulmonary embolism.

Signs of a blood clot in your leg include:

• swelling
• redness, darkening, or patches of discoloration
• pain
• tenderness

These symptoms are especially indicative of a blood clot when they occur in only one leg. That’s because you’re more likely to have a clot in one leg as opposed to in both legs. There are some other conditions and factors that could explain these symptoms, however.

To help distinguish a potential blood clot from other causes, Thomas Maldonado, MD, vascular surgeon and medical director of the Venous Thromboembolic Center at NYU Langone Medical Center, offered some more detailed thoughts on what someone might feel if they have a blood clot.

For one, the pain might remind you of a severe muscle cramp or charley horse. If your leg is swollen, elevating or icing the leg won’t reduce the swelling if it’s a blood clot. If icing or putting your feet up makes the swelling go down, you may have a muscle injury.

With a blood clot, your leg may also feel warm as the clot worsens. You may even notice a slight reddish or bluish hue to your skin. This may appear darker brown or discolored on darker skin.

You shouldn’t worry about a clot if the leg pain is made worse with exercise but relieved by rest. That’s most likely a result of poor blood flow through the arteries rather than DVT, says Maldonado.

Superficial venous thrombosis

Blood clots can also form in veins that are closer to the skin, known as superficial venous thrombosis, and cause a syndrome called superficial thrombophlebitis.

These can be caused by injury to the skin, including having an intravenous (IV) line placed, or other risk factors similar to those causing a DVT. While superficial thrombophlebitis can be painful, these types of blood clots usually don’t travel to the lungs.

Your doctor will examine you and may use an ultrasound to differentiate between a superficial blood clot and a DVT.

Blood clots may be more common in the lower legs, but they can happen in other parts of your body, too. Where clots form and where they end up influence which symptoms you have and the consequences.

For example, when a blood clot forms in the arteries of the heart and blocks blood flow, it can cause a heart attack. Or, a blood clot could travel to your lungs and cause a pulmonary embolism. Both can be life threatening and have similar symptoms.

Chest pain is a sign that something is wrong, but figuring out if it’s a heart attack, a pulmonary embolism, or just indigestion can be difficult.

According to Maldonado, the chest pain that comes with a pulmonary embolism may feel like sharp pains that get worse with each breath. This pain may also be accompanied by:

• sudden shortness of breath
• rapid heart rate
• possibly a cough

A pain in your chest that feels more like an elephant is sitting on you may be a sign of a potential cardiac event, such as a heart attack or angina. The pain that goes along with a potential heart attack may center on your chest.

It might also radiate to the left part of your jaw or your left shoulder and arm.

If you’re sweaty or have what feels like indigestion along with chest pain, that’s more cause for concern of a heart attack, says Patrick Vaccaro, MD, MBA, director of the Division of Vascular Diseases and Surgery at Ohio State University’s Wexner Medical Center.

Both conditions are serious, and both warrant further immediate medical attention.

Is your chest pain from congestion or wheezing? That’s more consistent with an infection or asthma, adds Maldonado.

Blood clots that form either in the chambers of your heart or within the carotid arteries in your neck have the potential to travel to your brain. That can cause a stroke, explains Sullivan.

The signs of a stroke include:

• weakness or numbness on one side of your body
• vision disturbances
• difficulty speaking clearly
• difficulty walking
• inability to think clearly

Unlike most of the other signs of blood clots, Vaccaro notes that you likely won’t feel pain with a stroke. “But there may be a headache,” he adds.

For more details of what having a blood clot might feel like, read some real stories from the National Blood Clot Alliance (NBCA) of people who have experienced one.

When a blood clot forms in one of the major veins that drain blood from your intestine, it’s called a mesenteric venous thrombosis.

Mesenteric venous thrombosis

A blood clot here can stop blood circulation of the intestine and cause internal damage in that area. Catching a clot in the abdomen early may lead to a better outlook.

Some people are more at risk for this type of clot than others, says Caroline Sullivan, nurse practitioner and assistant professor at Columbia University School of Nursing. This includes anyone with a condition that causes swelling of the tissues surrounding the veins, such as:

• appendicitis
• cancer
• diverticulitis
• pancreatitis, or acute swelling of the pancreas

Taking birth control pills and estrogen medications also increases your chances of having this type of clot.

The symptoms of a clot in the abdomen may include abdominal pain, bloating, and vomiting. If the stomach pain gets worse after eating or worse over time, it’s more likely to be associated with a clot, says Sullivan.

This pain might be severe and seem like it’s coming out of nowhere. It’s not something you’re likely to have experienced before, says Vaccaro, who compares it to “some of the worst pain an individual can experience.”

See your doctor if you think there’s even a small chance you could have a blood clot.

“The sooner the blood clot is diagnosed, the sooner treatment can be started and [the] chance of permanent harm can be reduced,” says Vaccaro.

A blood clot can form in the veins or the arteries, interrupting blood flow. It can cause pain, swelling, and red or dark, tender skin. The area around the blood clot may feel tight or sore like you have a muscle cramp or charley horse. Unfortunately, these symptoms of a blood clot can be confused with other conditions, including muscle pain and muscle injury.

It is also possible a blood clot will not cause any apparent symptoms. There is no way for you to know if your symptoms are the result of a blood clot or another issue. That’s why you should seek medical attention and an expert opinion if you have symptoms that could be the result of a blood clot. Quick treatment is necessary for successful treatment and future blood clot prevention.

Can you physically see a blood clot?

It is possible you will see evidence of a superficial venous thrombosis, or a blood clot in a vein that is closer to the skin. But it is still unlikely you still see the blood clot itself. Instead, you may experience redness, swelling, darkening of the skin over the vein, and hardening of the vein.

Can a blood clot go away on its own?

It is possible for blood clots to break apart on their own. This happens frequently with cuts and bruises. Blood clots form to stop the bleeding, and then naturally break apart after the wound has healed.

But there is no guarantee a blood clot will go away on its own, and the risk of more serious problems caused by a blood clot is very real. That’s why you should seek treatment if you believe you have a blood clot. Treatment can help break apart the clot and prevent future ones.

What are the first signs of a blood clot in the leg?

The first signs of a blood clot in the leg may include swelling, a change of color in the skin, and pain that starts out as dull and aching but can become sharp and intense. This pain may feel like a muscle cramp or charley horse.

How fast does a blood clot travel from the legs to the lungs?

A blood clot can break loose and travel from the legs to the lungs rapidly. It may take several days or weeks, or it can happen in a matter of minutes or hours. Once it has moved, a blood clot in the lungs can develop, which is known as an embolism. If the blood clot quickly cuts off blood supply, it is called an infarct.

How to check for a blood clot in your leg?

You can only monitor for the signs and symptoms of a blood clot in your leg. You cannot check to see if a blood clot is present yourself. That must be done by a medical professional.

Unfortunately, the signs and symptoms of a blood clot can be similar to other, less serious conditions, which is why some people write off the symptoms until it’s too late. If you have symptoms of a blood clot in your leg, make an appointment to see your doctor. If your doctor is unavailable, consider visiting an urgent care center or hospital emergency department.

What is the treatment for a blood clot in the leg?

Treatments for blood clots in the leg focus on preventing the clots from getting bigger, breaking loose and traveling elsewhere in the body, and then reducing the chances of future clots. These treatments include:

• Blood thinners: Anticoagulants (blood thinners) like heparin, warfarin (Jantoven), rivaroxaban (xarelto), or apixaban (Eliquis) can help break up existing blood clots and prevent them from growing. These medicines can also prevent future blood clots from forming.
• Clot busters: Thrombolytics can help break apart blood clots. However, they can cause serious bleeding, so they are typically reserved for people with severe clotting issues.
• Filters: A doctor may insert a filter in the vena cava, a large vein in the abdomen, to filter out clots that break loose and try to travel to the lungs. However, this is typically a last resort treatment in people who have suffered from bleeding complications while on blood thinners in the past or have continued to form blood clots despite being on blood thinners.

In the past, doctors have recommended using compression stockings to encourage blood flow through the legs so blood cannot pool and clot.

However, research has shown that using compression stockings may not actually reduce the risk of blood clots. Furthermore, it may actually increase the risk of post-thrombotic syndrome, a long-term complication of DVT. For this reason, the American College of Chest Physicians (CHEST) no longer recommends the use of compression stockings.

A blood clot is a blood clot that has turned from a liquid to a gel or semi-solid state. Blood clotting is a necessary process that can prevent you from losing too much blood when you get hurt or cut. When a clot forms inside one of your veins, it doesn’t always dissolve on its own. This can be a very life-threatening situation.

Contents of the article

An immobile blood clot will not usually harm you, but it is likely to move and become dangerous. If a clot breaks off and travels through the veins to the heart and lungs, it can get stuck and obstruct blood flow. This condition requires urgent medical attention.

If you think you may have a blood clot, contact your doctor immediately. The specialist will be able to review your symptoms and medical history and recommend what steps to take.

Types of blood clots

Your circulatory system is made up of vessels called veins and arteries that carry blood throughout your body. Blood clots can form in veins or arteries. An arterial clot causes symptoms immediately and requires emergency care. Symptoms of an arterial clot include severe pain, paralysis of parts of the body, or both. It can lead to a heart attack or stroke. A blood clot that forms in a vein may build up more slowly over time, but it can still be life-threatening. The most serious type of venous clot is deep vein thrombosis.

Without consulting a doctor, it is impossible to confirm its presence. But if you know the most common symptoms and risk factors, you can know when to see a specialist.

Possible blood clot without obvious symptoms. When the symptoms do appear, some of them coincide with the symptoms of other diseases. Below we have given the first signs and symptoms of a blood clot in the leg or arm, heart, abdomen, brain and lungs.

Blood clot in the leg or arm

Most often, a blood clot forms in the lower leg. A blood clot in a leg or arm may present with various symptoms, including:

• swelling
• pain
• weakness
• warm sensation
• reddish discoloration

Symptoms will depend on the size of the clot. This is why there may be no symptoms, or you may only have a slight swelling of the calf without much pain. If the clot is large, the entire leg may swell with severe pain. Blood clots on both legs or arms are rare. Your chances of having a blood clot are increased if your symptoms only affect one leg or one arm.

Blood clot in the heart or heart attack

Blood clot in the heart causing a heart attack. The heart is a less common place for a blood clot to form, but it can still happen. A blood clot in the heart can cause pain or a feeling of heaviness in the chest. Other potential symptoms are dizziness and shortness of breath.

Blood clot in the abdominal cavity

Severe abdominal pain and swelling may be symptoms of a blood clot somewhere in the abdomen. They may also look like symptoms of food poisoning.

Blood clot in the brain or stroke

Blood clot in the brain is also known as a stroke. A blood clot in the brain can cause a sudden and severe headache, as well as some other symptoms, including sudden difficulty speaking or seeing.

Blood clot in the lungs or pulmonary embolism

When a blood clot travels to the lungs, it is called pulmonary embolism (PE). Symptoms of PE may include:

• sudden shortness of breath not caused by exercise
• chest pain
• palpitations
• trouble breathing
• hemoptysis

What are the risk factors?

Certain risk factors increase the chances of a blood clot. A recent hospital stay, especially a long one or one associated with major surgery, increases the risk of thrombosis.

Common factors that may put you at moderate risk of a blood clot include:

• age, especially if you are over 65
• long trips, especially those that require you to sit for more than four hours at a time,
• bed regimen or prolonged sedentary lifestyle
• obesity
• family history of blood clots
• smoking
• cancer

When to see a doctor?

It is very difficult to diagnose a blood clot based on symptoms alone. Nearly 50 percent of people with DVT have no symptoms. That’s why it’s best to call your doctor if you think you have a blood clot. It is especially worth worrying about symptoms that appear out of nowhere. Call

additional tests to determine the exact cause. In many cases, the first step will be a non-invasive ultrasound (ultrasound). This test will show a picture of the veins or arteries, which will help the doctor make a diagnosis.

Intracardiac thrombi. Diagnosis and treatment

Blood clots can form not only in veins, but also in heart cavities and arteries.

Blood clots are a natural reaction of the body. They contribute to the restoration of damaged blood vessels. A blood clot is a blood clot that contains fibrin (a protein needed for blood clotting). But blood clots in the cavities of the heart is a completely different matter.

The most dangerous thing is that there are no symptoms by which one can suspect the presence of intracardiac thrombi. It is possible to detect a thrombus in the cavities of the heart only during diagnostics (echocardiography, etc.). And any symptoms (shortness of breath or suffocation) a person can only feel with pulmonary embolism.

Thrombi can be in the left or right cavities of the heart, in the atria or ventricles (more often these are parietal thrombi).

What are blood clots:

• Floating. These are partially attached thrombi. The danger is that the floating part of the thrombus may come off;
• Parietal, when the clot is completely attached to the wall of the chamber of the heart;
• Occlusive. The most dangerous! These clots cut off blood flow.

Thrombi in the left side of the heart

Most often, blood clots in the left cavities of the heart occur against the background of three diseases.

People at risk are:

• with mitral valve stenosis;
• with atrial fibrillation (atrial fibrillation):
• with postinfarction aneurysm of the left ventricle.

Blood clots in the left side of the heart – the risk of arterial thromboembolism, ischemic attacks or cerebral infarction! With the localization of blood clots in the left cavities of the heart, the arteries of the kidneys, upper and lower extremities, and the arteries of the intestine can also be affected.

Heart attacks and strokes

In arterial atherosclerosis and plaque rupture, a blood clot forms in the artery. As a result, myocardial infarction (necrosis of the organ tissue) can occur. If a thrombus located in the cavity of the left ventricle breaks off, then, spreading through the blood stream, it can clog the arteries of the brain (as a result, cerebral infarction occurs – ischemic stroke), kidneys (kidney infarction), intestines (intestinal infarction, mesenteric thrombosis), limbs (gangrene).

If a clot breaks off, it can spread with the bloodstream and close the vessel lumen! When the vessel is blocked, blood circulation is disturbed, which leads to oxygen starvation and tissue necrosis. This can cause complications such as myocardial infarction, PE, and even death.

If there is an open oval window in the intercardiac septum, blood clots from the veins of the lower extremities, the pelvis can move from the right atrium to the left and then enter the brain with the blood flow. The result is also a stroke.

Thrombi formed in cardiac aneurysm

After a heart attack, parietal thrombi may form in the left ventricle. They are seen by specialists with the help of echocardiography. This is the main type of diagnostic for the detection of blood clots in the cavities of the heart. If they are detected, a specialist may prescribe anticoagulants (in the absence of contraindications).

Thrombi formed in mitral valve stenosis

There is a special variety – a spherical thrombus in the left atrium. Such a thrombus is formed during mitral valve stenosis, in which outflow from the left atrium into the left ventricle is disturbed.

Thrombi formed during atrial fibrillation (atrial fibrillation)

In atrial fibrillation, blood clots are usually localized in the left atrial appendages. The ear is a protrusion of the atrium (it looks like a sac). Thrombi of the left atrial appendage can be detected most often only with transesophageal echocardiography. They are very difficult to detect with echocardiography.

Blood clots in the right side of the heart

The presence of a blood clot in the right side of the heart is fraught with complications in the form of thromboembolism of the branches of the pulmonary artery (a disease in which the arteries of the lungs are affected). PE is one of the most dangerous complications.
