Condition

Pulmonary Embolism (PE)

Anticoagulation management and long-term follow-up after pulmonary embolism.

Pulmonary embolism (PE) occurs when a blood clot — usually originating in the deep veins of the legs or pelvis — travels through the venous system and lodges in one of the pulmonary arteries, obstructing blood flow to part of the lungs. PE ranges from small subsegmental clots with minimal physiologic impact to massive emboli causing right heart failure and shock. The acute event is managed in the hospital, often by emergency medicine and pulmonary specialists. Long-term care after PE — anticoagulation management, evaluation for underlying causes, monitoring for chronic thromboembolic pulmonary hypertension, and managing post-PE syndrome — is the cardiologist's role. Dr. Kedan provides this longitudinal care with serial echocardiography and careful anticoagulation planning.

What Cardiolucent Evaluates

  • Complete hospital records review including imaging, severity, and treatments
  • Echocardiography with attention to right ventricular function and pulmonary pressures
  • POCUS at every visit for serial reassessment
  • Anticoagulant selection, dosing, and duration planning
  • Evaluation for provoking factors, thrombophilia, or occult malignancy
  • Monitoring for chronic thromboembolic pulmonary hypertension (CTEPH)
  • Coordination with hematology and pulmonary specialists at Cedars-Sinai when needed

Common Symptoms

  • Sudden shortness of breath
  • Chest pain, often pleuritic (worse with breathing)
  • Rapid heart rate
  • Cough, sometimes with blood
  • Lightheadedness or fainting
  • Leg swelling or pain suggesting concurrent DVT
  • Severe PE may present with collapse or shock — a medical emergency

Risk Factors

  • Prior DVT or PE
  • Recent surgery, hospitalization, or immobilization
  • Long-distance travel
  • Active cancer or recent chemotherapy
  • Pregnancy and postpartum period
  • Hormonal contraceptives or hormone replacement
  • Hereditary thrombophilia such as Factor V Leiden
  • Obesity, smoking, and chronic inflammatory conditions
  • Advanced age

How Cardiolucent Approaches Treatment

Most patients are treated with direct oral anticoagulants (DOACs) for at least three months, with duration extended based on whether the PE was provoked, unprovoked, or associated with ongoing risk such as malignancy. Dr. Kedan personalizes the duration carefully, balancing recurrence risk against bleeding risk. Serial echocardiography monitors recovery of right heart function and screens for chronic thromboembolic pulmonary hypertension, a potentially curable late complication. Thrombophilia and malignancy evaluation are coordinated with hematology when clinically appropriate.

Common Questions

Frequently Asked Questions

What is a pulmonary embolism?
A pulmonary embolism is a blood clot that has traveled to the lungs, lodging in one of the pulmonary arteries and obstructing blood flow. Most originate from deep vein thromboses in the legs or pelvis.
How is PE diagnosed?
CT pulmonary angiography is the most common diagnostic test, directly visualizing clots in the pulmonary arteries. Ventilation-perfusion (V/Q) scanning is used when CT is contraindicated. Echocardiography is used to assess the strain on the right heart, particularly in larger PEs.
How long do I need to be on a blood thinner?
The minimum duration is three months. Whether to continue beyond that depends on whether the PE was provoked by a transient factor (surgery, hospitalization), unprovoked, or associated with ongoing risk like cancer. Dr. Kedan reviews the trade-off between recurrence and bleeding individually.
Are DOACs better than warfarin?
For most patients with PE, direct oral anticoagulants (DOACs) such as apixaban and rivaroxaban are at least as effective as warfarin and easier to manage, with no routine blood monitoring and fewer interactions. Warfarin remains the right choice in specific situations such as mechanical heart valves.
Should I be tested for a clotting disorder?
Thrombophilia testing is reasonable in selected patients — those with unprovoked PE at a young age, recurrent clots, or strong family histories. Routine testing is not recommended for every patient with PE, and Dr. Kedan coordinates appropriate testing with hematology when indicated.
What is chronic thromboembolic pulmonary hypertension?
Chronic thromboembolic pulmonary hypertension (CTEPH) is a long-term complication in which residual clot organizes within pulmonary arteries, raising pressure and straining the right heart. It is uncommon but important to recognize because surgery (pulmonary endarterectomy) can be curative in many cases. Dr. Kedan monitors right heart function with serial imaging.
What is post-PE syndrome?
Some patients have persistent shortness of breath, reduced exercise tolerance, and decreased quality of life after PE, even when imaging looks improved. This is increasingly recognized as post-PE syndrome and is managed with rehabilitation and attention to coexisting conditions.
Can PE happen again?
Yes — recurrence risk depends on whether the PE was provoked or unprovoked, the strength of the provoking factor, and individual risk factors. Anticoagulation duration is calibrated to this risk, and Dr. Kedan reviews ongoing risk over time.
When can I fly again or travel long distances?
Once anticoagulation is established and you are clinically stable, travel is generally safe, though risk is not zero. Specific recommendations depend on time since the PE, type of anticoagulation, and other risk factors. Dr. Kedan provides individualized guidance.
How do I schedule a consultation?
