Acute Pulmonary Embolism

Description

Acute Pulmonary Embolism (PE) is a life-threatening condition caused by obstruction of pulmonary arteries, usually by thrombi originating from deep veins of the legs (DVT). It leads to impaired gas exchange, increased pulmonary vascular resistance, and right heart strain. Clinical features include sudden dyspnea, chest pain, hemoptysis, and tachycardia. Diagnosis involves D-dimer testing, CT pulmonary angiography, or V/Q scan. Treatment includes anticoagulation, thrombolysis, or surgical embolectomy. Prompt diagnosis and management are essential to reduce morbidity and mortality.
