Pulmonary Embolism

Content

Doctors usually treat pulmonary embolism with medicines called anticoagulants. They are often called blood thinners, but they don't really thin the blood. They help prevent new clots and keep existing clots from growing.

Most people take a blood thinner for a few months. People at high risk for blood clots may take it for the rest of their lives.

If symptoms are severe and life-threatening, "clot-busting" drugs called thrombolytics may be used. These medicines can dissolve clots quickly, but they increase the risk of serious bleeding. Another option is surgery or a less invasive procedure to remove the clot (embolectomy).

Some people may have a filter put into the large vein (vena cava) that carries blood from the lower body to the heart. A vena cava filter helps keep blood clots from reaching the lungs. This filter might be used if you have problems taking an anticoagulant.

Thrombosis Vs. Embolism

Thrombosis and embolism are both blood clots that reduce or block blood flow inside your blood vessels. They're two different yet serious conditions. Here's a look at the differences and similarities.

Thrombosis occurs when a blood clot (thrombus) forms locally in a blood vessel and slows or blocks the flow of blood. There are two types of thrombosis:

Venous thrombosis is when the blood clot blocks a vein. Veins carry blood from the body back into your heart. Deep vein thrombosis (DVT) is the most common type. It usually forms in the deep veins of your lower leg. But it can also form in the veins of your thigh, pelvis, or arm.

Arterial thrombosis is when the blood clot blocks an artery. The arteries carry oxygen-rich blood from the heart to the rest of your body.

Arterial thrombosis occur when deposits of fat and calcium (plaque) build up on the walls of the arteries that supply blood to the heart. When this buildup makes the artery walls thick, it's called arteriosclerosis. This thickening slows or blocks the flow of blood and causes blood pressure to build. If a plaque deposit bursts, a blood clot can form and cause a heart attack. If it blocks the arteries that carry blood to your brain, it can cause a stroke.

An embolus is any foreign substance that moves in your bloodstream until it blocks a blood vessel. An embolism is often caused when a thrombus or a piece of thrombus breaks off from where it formed and travels to another area of your body.

An embolism is a life-threatening condition and can cause serious complications such as stroke (clot in the brain) and pulmonary embolism (clot or blockage in the lung).

There are many types of thrombosis and embolism. Venous thromboembolism (VTE) is an umbrella term that doctors use to refer to blood clots that start in the veins, such as DVT. The most serious complication of these clots is a pulmonary embolism (PE). This is when the clot travels through the bloodstream to the lung, where it can cause permanent damage.

A DVT can occur in anybody at any age. But they are usually preventable and treatable if found early. This can also prevent a PE from forming.

Blood clot conditions like DVT and PE affect as many as 900,000 people per year in the U.S.

Risk factors for thrombosis and embolism include:

Family history of blood clots

Use of birth control, especially methods that use estrogen

Pregnancy

Injury to a vein, such as from surgery, or other trauma

Lack of movement for long periods, such as after surgery or during a long plane or car trip

Genetic blood clotting disorders

A central venous catheter

Older age, usually above 60

Smoking

Obesity

Health conditions, such as cancer, heart disease, lung disease, or Crohn's disease

Signs and symptoms vary for each person and depend on where the clot is located and how big it is. And it's possible that you might not have symptoms. In fact, it happens in about half the cases.

Common DVT symptoms include:

Pain

Swelling

Redness in the area

Tender to touch

If you notice this, tell your doctor right away.

Arterial thrombosis symptoms may include:

Numbness or weakness on one side of the body

Sudden change in your mental state

Chest pain

A visible change in skin color

Skin that's cool to the touch in the affected area

If you have any of these signs, call 911 and get immediate medical help.

If you have a PE, your symptoms may include:

Difficulty breathing

Fast and irregular heartbeat

Chest pain or discomfort, which worsens with a deep breath or coughing

Coughing up blood

Very low blood pressure

Lightheadedness, or fainting

PE is life-threatening. If you notice these symptoms, get medical help right away.

If your doctor suspects a thrombosis, they'll first do a detailed physical exam and history. Your doctor will also run imaging tests to help locate the clot, such as:

Your doctor may also use blood tests:

Blood count: Analyzes the makeup of your blood, including the platelets involved in clotting.

Troponin test: Looks for proteins called troponin I and troponin T that show up in your blood when your heart has been damaged, such as with a heart attack.

D-dimer test: Measures levels of a blood protein called D-dimer. A high level of D-dimer may mean that you have a blood clotting condition.

These tests can help your doctor pinpoint where the clot is located and what might have caused it. This will help come up with an appropriate treatment plan.

A pulmonary embolism is hard to diagnose, especially if you have heart or lung disease. Diagnostic tests are similar to thrombosis tests. Additional tests may include:

Chest X-ray

CT pulmonary angiography

Ventilation-perfusion scan

Pulmonary angiogram

Many different things will affect your treatment plan. Your doctor will look at:

Your age

Overall health

Medical history

How sick you are

Your tolerance for certain medicines, treatments, or therapies

If your condition is expected to get worse

Treatment options for thrombosis and embolism may include:

Blood-thinning medicines (anticoagulants)

Thin tubes (catheters) to widen the affected vessels

A wire mesh tube (stent) that holds a blood vessel open and stops it from closing

Clot dissolvers (thrombolytics)

Surgery (thrombectomy) to remove the clot

Inferior vena cava filters. These are little pieces of mesh surgically placed in the Inferior vena cava (a large vein in the abdomen) to prevent it from spreading to the heart or lungs.

If your embolism is caused by an air bubble, your doctor might recommend a hyperbaric chamber. It's a clear case long enough for you to lie down. The air pressure inside the chamber is higher than the normal air pressure outside. This helps to reduce the air bubble inside your body.

Complications may include:

A pulmonary embolism. A larger clot or many clots can raise your risk for death.

Postphlebitic syndrome. This is when a clot damages the vein and reduces overall blood flow to an area. This can cause leg pain, swelling, and discoloration.

Bleeding risk from blood-thinning drugs like warfarin and heparin

Stroke

Heart attack

If you have a thrombosis like DVT, the outlook is good. The symptoms usually go away in time with proper treatments like medication and lifestyle changes. It may take anywhere from 3-6 months for your clot to dissolve.

As for embolisms like PE, how well you recover depends on a few things such as:

What caused the embolism

The size of the clot

If the blood clot dissolves over time

About 33% of those with a DVT or PE have another blood clot within 10 years. Untreated or serious DVT or PE kills up to 100,000 people per year in the U.S. And about 25% of those with PE die suddenly with no symptoms.

It's hard to detect a blood clot in your body before it forms. But they are preventable. The key to preventing a clot from becoming a deadly embolism is lifestyle changes.

You should:

Stay active with regular exercise

Maintain a healthy weight

Eat a balanced diet

Quit smoking

If you have a DVT, it's important to follow your treatment plan closely to stop it from progressing to PE. If you notice signs and symptoms of an embolism, call 911 immediately or head to the nearest hospital for medical help.

How Blood Clots In The Lungs Affect Your Health

Blood clots in the lungs, also known as pulmonary embolisms, can be a serious medical condition that affects your overall health. A pulmonary embolism occurs when a blood clot, typically originating in the deep veins of the legs or other parts of the body, travels to the lungs and blocks one or more arteries. This condition can have severe consequences, including damage to the lungs, reduced oxygen levels in the blood, and even death if not treated promptly. Understanding the causes, symptoms, and treatment options for pulmonary embolisms is crucial for maintaining your health and preventing potential complications.

What causes blood clots in the lungs?

Several factors can contribute to the formation of blood clots that may eventually travel to the lungs. These include:

Deep vein thrombosis (DVT): This is the most common cause of pulmonary embolisms. DVT occurs when blood clots form in the deep veins of the legs or other parts of the body and then dislodge and travel to the lungs.

Immobility: Prolonged periods of inactivity, such as long flights or bed rest, can increase the risk of blood clot formation. When you are immobile, blood flow in the veins slows down, making it easier for clots to form.

Medical conditions: Certain medical conditions, such as cancer, heart disease, and respiratory diseases, can increase the likelihood of developing blood clots. Additionally, some inherited blood disorders make individuals more prone to clotting.

Surgery and trauma: Major surgeries, especially those involving the legs, hips, or abdomen, can lead to blood clot formation. Trauma or injury to blood vessels can also trigger clot development.

Lifestyle factors: Smoking, obesity, and a sedentary lifestyle are significant risk factors for blood clot formation. These factors can contribute to poor circulation and increased clotting tendencies.

Symptoms of blood clots in the lungs

Recognizing the symptoms of a pulmonary embolism is crucial for seeking timely medical intervention. The symptoms can vary depending on the size of the clot and the area of the lung affected. Common symptoms include:

Shortness of breath: This is often the most noticeable symptom and can occur suddenly or gradually. It may worsen with exertion but can also be present at rest.

Chest pain: The pain associated with a pulmonary embolism is usually sharp and stabbing. It may worsen when you breathe deeply, cough, or bend over.

Cough: A persistent cough that may produce bloody or blood-streaked sputum can be a sign of a pulmonary embolism.

Rapid heart rate: An elevated heart rate, known as tachycardia, often accompanies a pulmonary embolism as the heart works harder to pump blood through blocked arteries.

Dizziness or fainting: Reduced oxygen levels in the blood can lead to dizziness, lightheadedness, or fainting spells.

Leg pain or swelling: If the blood clot originated in the deep veins of the legs, you might experience pain, swelling, and tenderness in the affected leg.

Diagnosis and treatment of pulmonary embolism

Diagnosing a pulmonary embolism typically involves a combination of medical history, physical examination, and diagnostic tests. Common diagnostic methods include:

D-dimer test: This blood test measures the presence of clot degradation products in the blood. Elevated levels may indicate the presence of a clot, prompting further testing.

Imaging tests: Imaging techniques such as chest X-rays, CT scans, and pulmonary angiography can help visualize the blood vessels in the lungs and detect any blockages.

Ultrasound: If deep vein thrombosis is suspected as the source of the embolism, an ultrasound of the legs may be performed to identify clots.

Treatment options

The treatment for a pulmonary embolism aims to prevent further clot formation, dissolve existing clots, and manage symptoms. Common treatment options include:

Anticoagulant medications: Also known as blood thinners, these medications help prevent new clots from forming and existing ones from growing larger. Common anticoagulants include warfarin, heparin, and direct oral anticoagulants (DOACs).

Thrombolytic therapy: In severe cases, thrombolytic medications, also known as clot busters, may be administered to dissolve the clot quickly. These drugs are usually reserved for life-threatening situations due to the risk of significant bleeding.

Surgical intervention: In rare cases where medications are not effective or feasible, surgical procedures such as embolectomy (surgical removal of the clot) or placement of a vena cava filter (to prevent clots from reaching the lungs) may be necessary.

Supportive care: Supplemental oxygen therapy and pain management may be required to alleviate symptoms and improve oxygen levels in the blood.

Preventing blood clots in the lungs

Preventive measures can significantly reduce the risk of developing blood clots and subsequent pulmonary embolisms. Key prevention strategies include:

Stay active: Regular physical activity helps promote healthy blood circulation and reduces the risk of clot formation. Avoid prolonged periods of immobility by taking breaks to walk and stretch, especially during long journeys or while recovering from surgery.

Maintain a healthy weight: Obesity is a significant risk factor for blood clots. Achieving and maintaining a healthy weight through a balanced diet and regular exercise can lower your risk.

Quit smoking: Smoking damages blood vessels and increases the likelihood of clot formation. Quitting smoking can improve your overall cardiovascular health and reduce clotting risks.

Manage medical conditions: Proper management of chronic conditions such as heart disease, diabetes, and high blood pressure can help reduce the risk of blood clots.

Follow medical advice: If you have a history of blood clots or are at high risk, follow your healthcare provider's recommendations for preventive measures, including the use of anticoagulant medications if prescribed.

Long-term effects of pulmonary embolism

The long-term effects of a pulmonary embolism can vary depending on the severity of the initial event and the effectiveness of treatment. Potential long-term consequences include:

Chronic thromboembolic pulmonary hypertension (CTEPH): This condition occurs when clots do not fully dissolve and lead to persistent high blood pressure in the lungs' arteries. CTEPH can cause ongoing shortness of breath, fatigue, and heart failure.

Reduced quality of life: Individuals who have experienced a pulmonary embolism may have ongoing symptoms such as shortness of breath, chest pain, and fatigue, affecting their daily activities and overall quality of life.

Recurrence risk: There is a risk of recurrent pulmonary embolisms, especially if the underlying risk factors are not addressed. Long-term anticoagulant therapy may be necessary to prevent future clots.

Post-thrombotic syndrome (PTS): If the initial clot originated in the legs, there is a risk of developing PTS, characterized by chronic pain, swelling, and skin changes in the affected leg.

Conclusion

Blood clots in the lungs are a serious medical condition that can significantly impact your health if not promptly diagnosed and treated. Understanding the causes, recognizing the symptoms, and seeking timely medical intervention are crucial for preventing complications and improving outcomes. By adopting preventive measures and managing underlying risk factors, you can reduce the likelihood of developing pulmonary embolisms and protect your overall health. If you suspect you have a blood clot or experience symptoms of a pulmonary embolism, seek medical attention immediately to ensure the best possible outcome.
