Contents

What Is Pulmonary Embolism?

“Embolism” means plug or stopper in greek. A blockage in the artery that supplies the blood to the lungs (pulmonary artery) is called pulmonary embolism. It affects around 1 in 1,000 people in the US and is one of the most common cardiovascular diseases. It can be fatal, as it prevents oxygen from reaching the lungs.

The block or embolus is most commonly a blood clot. The embolus can form in one part of the body and block the blood flow to other parts by traveling through the blood vessels. A thrombus, unlike an embolus, forms and stays in the same place. Prompt treatment can prevent complications and reduce death rates.

What Are the Symptoms of Pulmonary Embolism?

The symptoms vary depending on the size of the embolus, existing lung and heart problems, and the amount of lung involved. The common signs and symptoms of pulmonary embolism include:

What Causes Pulmonary Embolism?

Pulmonary embolisms are most often caused by blood clots blocking the deep veins in the body, which is called deep vein thrombosis. These blood clots usually originate in the arteries of legs or pelvis, and result from:

Apart from blood clots, sometimes, the blood vessels get blocked by:

What Are the Risk Factors for Pulmonary Embolism?

Factors that increase the risk of developing deep vein thrombosis (DVT) and pulmonary embolism include:

What Are the Complications of Pulmonary Embolism?

Some of the common complications of pulmonary embolism are:

How Is Pulmonary Embolism Diagnosed?

An underlying heart or lung disease like hypertension or emphysema makes diagnosing PE difficult. Your doctor will ask about your overall health and any pre-existing conditions, and might tell you to get one or more of the following tests done:

What Are the Treatment Options for Pulmonary Embolism?

Depending on the size and location of the blood clot, your doctor will plan your treatment. Small clots can be broken up with medicines like:

only in case of an emergency.

For clots that cause serious blood flow restriction to the heart and lungs, surgery may be necessary. The surgical options are:

What Are Ways to Prevent Pulmonary Embolism?

If you have any of the factors that increase the risk of PE, try the following to prevent blood clots:

The underlying cause has to be treated, after treatment for PE. Your doctor will prescribe blood thinners to prevent more blood clots. To know more about preventing such blood clots, consult a doctor online.

Frequently Asked Questions


1.

How painful is a pulmonary embolism?

Pulmonary embolism causes sharp pains, which gets worse with each breath. Such chest pain does not get better with rest. It can also cause difficulty breathing and rapid heart rate.

2.

How dangerous is a pulmonary embolism?

A PE can be fatal if the embolus blocks the blood flow to major organs like the heart and lungs. It can also damage other organs.

3.

What are some natural ways to cure a pulmonary embolism?

Foods that help reduce blood clots are turmeric, ginger, peppers, vitamin E rich foods, garlic, grape seeds, cinnamon, and Bromelain (an enzyme extracted from pineapple).

4.

Can a person survive a pulmonary embolism?

Prompt diagnosis and treatment of pulmonary embolism reduce the fatality rate. But most often, this condition goes undiagnosed because of underlying heart or lung disease, which results in the death of one-third of people with PE.

5.

Who is at high risk for pulmonary embolism?

People with deep vein thrombosis (DVT), which is a blood clot in the deep vein like the leg, are mostly affected by PE. The factors that increase the risk of DVT are cancer, fracture, sedentary lifestyle, obesity, smoking, pregnancy, and people older than 60 years.

6.

Can pulmonary embolism go away on its own?

Small clots can get cleared on its own by the body. The body activates a protein called plasmin, which is present in the clot. This plasmin, once activated, breaks down the clot.

7.

How long can you live with a pulmonary embolism?

The survival rate depends on the size of the embolus. The first week after the clot has formed is the risk period. If you survive that, the clot might take months to years to dissolve. You might have to live with shortness of breath, pulmonary hypertension, and exercise intolerance.

8.

How serious is a pulmonary embolism?

The survival rate of PE is between 77 % and 94 %. A large embolus can block the blood supply to the lungs, which can reduce the blood oxygen levels. This, in turn, affects other organs.

9.

What happens if a pulmonary embolism goes untreated?

An embolus can dissolve on its own. But in some cases, if PE is left untreated, it can cause heart attack, pleural effusion, pulmonary infarction, arrhythmia, pulmonary hypertension, and death.
