Life expectancy for someone with a pumonary embolism (PE) will depend on the type and severity, individual factors, and how soon the person receives a diagnosis and treatment. Doctors use a scale to estimate the likelihood of surviving at least 30 days.
A pulmonary pulmonary embolism (PE) blocks the pulmonary artery from supplying blood to the lungs.
Doctors use a pulmonary embolism severity scale to assess the likelihood or a person with a PE surviving
However, there is a good chance of recovering from a PE if a person receives prompt medical treatment.
Read on about the symptoms and risk factors of PEs, the life expectancy, mortality rates, and outlook for a person diagnosed with PE.
PE is a potentially life threatening blockage in the pulmonary artery. It causes a blood clot to travel through the bloodstream and reach the lungs.
Common symptoms of PE may include:
- pain associated with deep breathing
- shortness of breath (dyspnea)
- increased heart rate (tachycardia)
- rapid breathing
If a person has trouble breathing or has other severe symptoms, they should seek emergency medical assistance immediately.
Blood clots typically form in deep veins in the lower leg, thigh, or pelvis. This is a condition known as deep vein thrombosis (DVT).
The risk factors for PE can either be genetic or acquired, which may relate to nonsurgical or surgical factors.
- thrombophilia (a condition that increases a person’s risk of blood clots)
- protein C deficiency
- protein S deficiency
- prothrombin gene mutation
The most common acquired mutations (behavioral or external factors) may include:
People between the ages of
A person with associated cardiovascular comorbidities such as heart disease may also experience a higher mortality rate due to PE.
Prompt treatment is necessary to help prevent serious complications. Treatment for PE aims to help prevent clots from growing and the formation of new clots.
Blood thinners, or anticoagulants, are the most common treatment for PE. Doctors administer these using an intravenous injection, and a person can transition into taking them as an oral tablet when discharged from the hospital. The length of treatment depends on the underlying cause.
Most people make a full recovery after a PE, but some may experience long-term symptoms, such as shortness of breath. The recovery period may vary depending on the severity of the PE and the person’s overall health.
PEs can be one of the following types (with associated mortality rates from
- acute small — less than 1%
- acute massive — over 20%, irrespective of treatments
- acute submassive — ranges from 5–25%
- subacute massive PE — depends upon incidence of malignancies
- pulmonary infarction — not commonly associated with mortality, and linked to conditions such as alveolar hemorrhages and pleuritis
The most severe form of PE is acute massive. Approximately
Some people can develop the following complications:
- post-thrombotic syndrome may cause persistent swelling, pain, and discoloration of the skin in the affected area
- chronic lung damage
- further clotting
- psychological issues such as anxiety or depression
According to the Centers for Disease Control and Prevention (CDC), approximately
The following tips may help improve a person’s condition after PE.
- Having regular follow-ups: Doctors should monitor a person’s condition and assess whether they need to continue treatment.
- Looking for warning signs: People should contact a doctor if they are experiencing symptoms such as pain, swelling, easy bruising, and unexpected bleeding.
- Having routine blood tests: These tests will monitor the dose of the medications, so doctors can make any adjustments if required. Ultrasounds may also help monitor the size of the blood clot.
There is a greater awareness of certain causes of PE. For example, DVT may develop on journeys lasting longer than 6 hours. Doctors sometimes recommend people wear compression socks to help prevent PE occurrences.
The outlook associated with PE depends on the type and severity of the embolism.
People with initial symptoms must immediately seek medical care to help prevent further complications. After recovery, a person’s doctor may suggest lifestyle changes such as quitting smoking and having routine checkups to reduce any further risks of complications from a PE.
Treatments are available to help people recover from PE, including anticoagulants. This treatment helps prevent the extension of clots as well as new clot formation.
