BACKGROUND: To evaluate the relationship between site of @entity1188 (anterior vs. inferior) and circadian variation in @entity1 with @entity10260 @entity583 ( @entity583 ) in a Turkish cohort. MATERIAL/METHODS: This restrospective study enrolled 465 @entity1 (407 male, mean age 65  7 years) with @entity583 . @entity1 were then categorised into 4 6-hour increments according to the time of day during which the symptoms began (12:00 AM-06:00 AM, 06:00 AM-12:00 PM; 12:00 PM-06:00 PM and 06:00 PM-12:00 AM hours). Characteristics of @entity1 by site of @entity1188 (anterior vs. inferior) were compared. RESULTS: The frequency of onset of @entity697 as determined by onset of @entity158 demonstrated significant circadian variation among the 4 time periods, demonstrating bimodal peaks (afternoon and morning) and a trough between 06:00 PM to 06:00 AM. The incidence of occurrence of MI between 06:00 AM to 06:00 PM was 4.50 times that of the average frequency of the remaining 12 hours of the day. The frequency of onset of @entity697 as determined by onset of @entity158 exhibited significant circadian variation among the 4 time periods, demonstrating bimodal peaks (midnight to 06:00 AM and 06:00 AM to noon) and a trough between noon to midnight. The incidence of occurrence of MI between midnight to noon was 4.25 times that of the average frequency of the remaining 12 hours of the day. CONCLUSIONS: Different circadian periodicity in the time of onset of @entity583 was found regarding @entity1188 site in a Turkish cohort. This may be related to genetic and   or demographic characteristics of the Turkish population.
