What follow up is needed after a pulmonary embolism?Â
After being diagnosed with a pulmonary embolism, a structured follow-up plan is necessary to ensure the blood clot is resolving and to minimize the risk of a recurrence. This process involves regular reviews with healthcare professionals to monitor the effectiveness of anticoagulant medication and to assess the patient’s physical recovery. In the UK, follow-up care is guided by specific clinical standards designed to support long term health and prevent future complications related to venous thromboembolism.

Initial medical review after hospital dischargeÂ
Patients are typically required to attend their first follow-up appointment within a few weeks of leaving the hospital to confirm that their treatment is progressing as expected. This initial review is usually conducted by a specialist haematology team or a dedicated thrombosis clinic to check for any side effects of the medication and to address any lingering symptoms such as breathlessness or fatigue. The NHS states that after a pulmonary embolism, you will usually have regular check-ups to see how your treatment is working and to discuss how long you need to take anticoagulants.
Monitoring and medication reviewsÂ
The frequency of follow-up depends on the type of anticoagulant prescribed and whether the patient has any other underlying health conditions. Patients taking warfarin require frequent blood tests to check their international normalised ratio (INR) levels, whereas those on Direct Oral Anticoagulants (DOACs) may only need annual kidney and liver function tests. NICE guidelines recommend that all patients should have a review at three months to decide whether to continue or stop anticoagulant treatment based on their risk of recurrence and bleeding.
Assessing the cause and future riskÂ
A key part of follow-up care is identifying why the pulmonary embolism occurred to prevent it from happening again. If the clot was “unprovoked”, meaning there was no obvious trigger like surgery or injury, doctors may investigate further for underlying conditions or genetic clotting disorders. This assessment helps determine if the patient needs to stay on blood thinners for a longer period, sometimes even for life, to ensure their safety.
| Appointment Type | Typical Timing | Primary Objective |
| Initial Clinic Review | 2 to 4 weeks | Monitor stability and medication side effects. |
| Three-Month Review | 3 months | Decide on the duration of anticoagulant therapy. |
| Annual Review | Every 12 months | Check kidney function and review ongoing risk. |
| Haematology Specialist | As required | Investigate genetic or complex clotting causes. |
Physical recovery and symptomatic monitoringÂ
Follow-up care also focuses on the patient’s physical rehabilitation and the gradual improvement of respiratory symptoms. Doctors will monitor how well the patient can manage physical exertion and may offer advice on graduated exercise to help improve lung capacity and overall stamina. While most patients recover fully, some may experience persistent breathlessness, which might require further investigation to rule out rare complications like chronic thromboembolic pulmonary hypertension.
ConclusionÂ
Follow-up care after a pulmonary embolism is a vital process involving clinical reviews, medication monitoring, and risk assessments. These appointments ensure that the clot is managed effectively and that the patient is on the safest possible treatment path for their specific circumstances. Adhering to the follow-up schedule is the best way to ensure a full recovery and long-term protection against future clots. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
How often will I need blood tests during follow-up?Â
If you are on warfarin, you will need regular tests to check your INR, but if you are on DOACs like apixaban, you may only need blood tests once or twice a year.Â
Will I have another scan to check if the clot has gone?Â
Repeat scans are not always routine; they are usually only performed if your symptoms are not improving as expected or if a new complication is suspected.Â
Who will manage my follow-up care?Â
Your care will typically be managed by a combination of your GP and a specialist hospital-based thrombosis or haematology clinic.Â
What happens if I forget to attend a follow-up appointment?Â
It is important to reschedule as soon as possible, as these reviews are essential for deciding how long you must safely remain on blood thinners.Â
Can I be discharged from follow-up care?Â
Most patients are discharged from specialist clinics once their course of treatment is finished, but they will still be monitored by their GP.Â
What should I discuss at my follow-up review?Â
You should mention any new or worsening symptoms, any side effects like unusual bruising, and any plans for travel or surgery.Â
