How do you know if you have a pulmonary embolism?

A pulmonary embolism (PE) occurs when a blood clot blocks one or more arteries in the lungs. Symptoms can include sudden onset of chest pain, shortness of breath, and rapid heart rate. The chest pain associated with PE is often sharp and may worsen with deep breathing. Shortness of breath may come on suddenly and can range from mild to severe. Some may experience anxiety or a sense of impending doom, which can complicate distinguishing PE from anxiety disorders.

Clinicians typically evaluate for PE by looking at risk factors such as recent surgery, prolonged immobility, history of deep vein thrombosis, or known clotting disorders. Standard evaluation often involves imaging tests like a CT pulmonary angiography or a ventilation-perfusion (V/Q) scan. Blood tests like D-dimer may also be used to assess the likelihood of clotting.

Recovery from a PE varies, but it often involves anticoagulation therapy to prevent further clots. The medical literature emphasizes the importance of early detection and treatment to reduce complications. Anyone with concerns about symptoms or risk factors for pulmonary embolism should discuss their specific situation with their healthcare provider.
