Hypercoagulability in Obstructive Sleep ApneaGuardiola, Juan J. M.D.; Fletcher, Eugene C. M.D.; Alhariri, H. M.D.; Hasan, Nuzhat M.D.Clinical Pulmonary Medicine: July 2001 - Volume 8 - Issue 4 - p 238-241 Topics In Pulmonary Medicine Buy Abstract Author InformationAuthors In patients with obstructive sleep apnea, blood hypercoagulability may contribute to an increased risk of cardiovascular events. The main causes of hypercoagulability related to obstructive sleep apnea are hyperfibrinogenemia, decreased fibrinolytic activity, platelet function abnormalities, erythrocytosis, and vascular endothelial dysfunction. This hypercoagulable state may be related to recurrent episodic hypoxia during sleep apnea.
