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. Pathophysiology and Etiology
Treatment strategies are dictated by the patient's hemodynamic stability and risk category. Download Embolie pulmonaire aiguГ« pdf
: Roughly 70% to 80% of emboli arise from proximal deep veins in the legs or pelvis. Acute Pulmonary Embolism (PE) is a critical cardiovascular
: Once a clot lodges in the pulmonary vascular bed, it increases pulmonary vascular resistance, which can lead to acute right ventricular (RV) failure and hemodynamic collapse. : Roughly 70% to 80% of emboli arise
: D-dimer testing is highly sensitive for ruling out PE in low-to-intermediate risk patients. Cardiac biomarkers like Troponin and BNP help assess myocardial injury and RV strain.
