Abstract

Objectives:This study aimed to investigate the circadian variation in stroke types, ischemic stroke subtypes, and Sasang constitutions. Methods:295 patients with acute stroke within 14 days onset were included, who were admitted to Kyunghee Oriental Medical Center from October 2005 to May 2007. The stroke onset time was subdivided into four groups of 6-hour intervals in a day. Stroke types, ischemic stroke subtypes, and Sasang constitutions in four groups were examined. Results:Most ischemic stroke occurred between 6:01-12:00 hours (30.2%). For ischemic stroke subtypes, the peak period of small-vessel occlusion was between 6:01-12:00 hours (33.2%), large-artery atherosclerosis was most common between 12:01-18:00 hours (39.5%), and cardiac embolism was most frequent between 18:01-24:00 hours (50%). In terms of Sasang constitution, Soyeumin and Taeyeumin were most common between 6:01-12:00 hours (36.4% versus 41.5%, respectively), but the peak time of Soyangin was between 12:01-18:00 hours (35.2%). Conclusion:Most ischemic stroke events occurred in the mid-to-late morning hours in the present study and there was a circadian variation of onset in ischemic stroke subtypes and Sasang constitution.
