&description=Purpose was the study influence of chronobiological factors (seasons, time of day, days of week) on the frequency of occurrence of ACS/AMI. Material and methods: Epidemiological features of AMI and ACS were studied among the constant population of one of districts of Tashkent. The research was carried during one year (from 1.07.2009 to 30.06.2010). For the collection of information there were used card of the emergency medical care, ambulatory cards, card of patients discharged from hospital, history of diseases, statistical coupons, journals of electrocardiogram (ECG) record and registration, journal of hospitalization registration and journals of registrations of the patient refusals from hospitalization. Results: The register were included 683 patients with AMI/ACS, of them men - 67,9% and women - 32,1%. According to our data January and December appeared to be the less favourable months, and Mаy and June were the most favourable. The analysis of the incidence rate of ACS/AMI with regards to seasons of year showed, that the greatest quantity of patients as well as of lethal outcomes (23,0% and 33,9%, respectively) at the prehospital stage was noted on the autumn-winter period. Lethal outcomes at a pre-hospital stage on time of days were registered in night (0.00 till 5.59 o'clock) and morning (6.00 till 11.59 o'clock) hours (29,6% and 27,1% accordingly) is slightly more often. According to our data the highest incidence of ACS/AMI is defined at the beginning of week - Monday and Tuesday (18% and 16%, respectively) and at weekend - Saturday (15,5%). In the rest days of week the tendency preserved almost uniform. Thus, our researches have confirmed a universal tendency that episodes ACS/AMI on time of days meet in the morning is more often, and night time of days is interfaced to higher probability lethality at a pre-hospital stage.&picture=http://www.aascit.org/aascit/decorators/img/journal/979.jpg)
