: Roughly 70% to 80% of emboli arise from proximal deep veins in the legs or pelvis.
Acute Pulmonary Embolism (PE) is a critical cardiovascular emergency characterized by the sudden obstruction of a pulmonary artery, typically by a blood clot originating from deep vein thrombosis (DVT) in the lower limbs. As a leading cause of in-hospital mortality, its management requires rapid risk stratification and adherence to standardized clinical guidelines.

: The mainstay for most patients. Low-molecular-weight heparin (LMWH) is often preferred over unfractionated heparin (UFH) for initial treatment. Long-term management typically involves Direct Oral Anticoagulants (DOACs) like apixaban or rivaroxaban. : Roughly 70% to 80% of emboli arise
