Effect of low-molecular-weight heparin and urokinase on pulmonary arteries involved in pulmonary embolism.

Background: Pulmonary embolism (PE) is a common and often fatal disease. Early after pulmonary thromboembolism, inflammation and associated intimal hyperplasia occur within the pulmonary arteries, similar to what is observed with chronic thromboembolic pulmonary hypertension. This study tested the hypothesis that thrombolytic and anticoagulant agents would have anti-inflammatory effects or inhibit intimal hyperplasia of involved pulmonary arteries.
