Which preventive measure is recommended to reduce the risk of pulmonary embolism?

Anticoagulant prophylaxis is the most effective way to prevent pulmonary embolism because it directly reduces clot formation in the venous system, which is the source of most PE events. Medications like heparin work by enhancing antithrombin III, inhibiting thrombin and factor Xa, thereby decreasing the development and growth of DVTs. In postoperative or immobilized patients, this pharmacologic approach significantly lowers the risk of clots traveling to the lungs. While physical methods such as compression stockings or pneumatic devices and encouraging early ambulation help by promoting venous return and reducing stasis, they are generally used as adjuncts or when anticoagulation is contraindicated. If anticoagulation is appropriate, it’s the recommended preventive strategy to minimize pulmonary embolism risk.
