    We studied under conditions of the Extreme North on the basis of Medical Unit “GAZPROM DOBYCHA YAMBURG” 93 males at the age from 20 till 59 years, mean age 45,8 ± 6,9 years. The results of 12 - month study of 93 males with 1,2 degree AH treated with chronotherapy and treated with usual antihypertensive therapy ( lisinopril 5 mg \ day). 24-hour ambulatory blood pressure monitoring (ABPM) was performed in all patients, individual cosinor-analysis with the definition chronotype circadian rhythm of BP. In therapy used chronotherapy approach, which includes the method of preventive chronotherapy and method of “pacing”. The study showed that under the conditions of circumpolar shift work mainly atypical chronotype BP (50 % of evaluable patients), which leads to the importance chronocorrection therapy of AH. Chronotherapy interventions under the conditions of circumpolar shift work for a year has a pronounced hypotensive and chrono stabilizing effects.В условиях вахтового поселка на базе медико-санитарной части ООО «ГАЗПРОМ ДОБЫЧА ЯМБУРГ» обследованы мужчины 20-59 лет, средний возраст составил 45,8 + 6,9 лет. Представлены результаты 12- месячного исследования 93 мужчин с А Г1,2 степени, пролеченных в условиях хронотерапии и традиционного назначения гипотензивных препаратов (лизиноприл 5 мг\сутки). Всем обследованным проведено суточное мониторирование АД (СМАД), индивидуальный косинор-анализ данных с определением хронотипов суточных ритмов АД. В терапии использован хронотерапевтический подход, включающий в себя 2 метода: «превентивный» и метод «навязывания ритма». Проведенное исследование показало, что в условиях заполярной вахты преобладают атипичные хронотипы АД (у 50% обследованных пациентов), что обуславливает значимость хронокоррекции терапии АГ. Хронотерапевтическое вмешательство в условиях заполярной вахты в сравнении с обычным лечением в течение года оказывает выраженный гипотензивный и хроностабилизирующий эффект

    Prognostic significance of atypical normotonsive chronotypes blood pressure in the development of hypertension in shift workers of the Arctic polar region

    During the prospective one-year study in conditions of shift work in the Arctic 173 men with normal BP and with a negative history of hypertension (mean age 40.2+4.1 years) were examined. In total north experience was 16.5i6.8 years; work experience 11.2±3.8 years and office BP 123.4±7.5\80.5±5.5. All patients underwent ABPM, individual cosinor-data analysis to determine circadian rhythms chronotypes 1 time every 3 months. Based on the results of the study of chronobiological parameters in individuals with normal BP the role of DS in the formation of chronotypes of blood pressure diurnal rhythms in normotensive subjects was assessed, moreover tipepidine chronotypes AD highlighted as the main disturbances of circadian rhythm in the conditions of polar watches. Atypical normotensive chronotypes were characterized by more evident structural changes of heart and vessels. Chronobiological approach in comparison with standard analysis of ABPM showed higher diagnostic sensitivity, specificity and efficiency. Logistic regression revealed prognostic significance of normotensive atypical chronotypes compared to the main risk factors (smoking, low phisical activity, body mass index, dyslipidemia, age, duration of North and camp experience, the mode and type of watch).В течение проспективного годового наблюдения в условиях вахтового режима труда в Заполярье обследованы 173 мужчины с нормальным АД и с отрицательным анамнезом по гипертонии, средний возраст — 40,2±4,1 лет; северный стаж -16,5+6,8 лет; стаж работы вахтой • 11,2±3,8 лет; офисное АД 123.4±7,5\80,5±5,5(ммрт. ст.). Всем пациентам выполнено СМАД, индивидуальный косинор-анализ данных с определением хронотипов суточных ритмов АД 1 раз в 3 месяца. На основе результатов изучения хронобиологических параметров у лиц с нормальным АД показана роль десинхроноза в формировании хронотипов суточных ритмов АД у нормотензивных лиц, атипипичные хронотипы АД выделены, как ведущие нарушения суточной ритмики в условиях заполярной вахты. Атипичные нормотензивные хронотипы характеризовались более выраженными структурными изменениями сердца и сосудов. Хронобиологический подход в сравнении со стандартным анализом СМАД показал более высокие диагностические чувствительность, специфичность и эффективность. Метод логистической регрессии выявил прогностическую значимость нормотензивных атипичных хронотипов АД в сравнении с основными ФР (курение, НФА, ИМТ, дислипидемия, возраст, длительность северного и вахтового стажа, режим и тип вахты)

    Aim. To determine the most significant risk factors (RF) associated with subclinical carotid atherosclerosis (SKA) in people working rotating scheme (RS) in the Arctic, and the role of high blood pressure (BP) in the formation of the atherosclerotic process.Material and methods. We included 424 men — employees (RS): group 1 (n=294) BP >140/90 mm Hg, group 2 (n=130) with BP <140/90 mm Hg, consistent in age — 46,9+5,8 years (p=0,435), northern work experience — 12,5+4,6 years old (p=0,597). Office blood pressure was 149,4+13,3/97,1+7,3 mm Hg in group 1 (patients with arterial hypertension) and 123,4+7,5/80,5+5,5 mm Hg in group 2. An ultrasound study of the common carotid arteries (CCA) was conducted with the determination of intima-media thickness (IMT) and atherosclerosis plaque (ASP) in the carotid arteries using the NASCET method. We studied blood lipids andRF (smoking, low physical activity, dyslipidemia, overweight (BMI), psycho-emotional overstrain.Results. In the RS conditions IMT and ASP prevalence in men significantly depend on the BP level. At the same time, the definition of the main RF in men of 30-59 years only in 23% significantly influenced the IMT of CCA. It is described by the multiple regression formula: IMT= 0,09+0,129•ASP+0,010•Age+0,06•Smoking+0,02•Atherogenic index+0,11•systolic BP+0,005•animal fat intake >30% of daily calorage. The logistic regression data showed a significant dependence of ASP imaging probability in the CCA upon age, BP, BMI and the psychoemotional overstrain. The formula of the logistic regression model is: ASP=-13,746+0,103•Age+0,507•BMI+0,037•diastolic BP+0,021•systolic BP+2,2394MT-0,514•psycho-emotional overstrain.Conclusion. The role of elevated BP as one of the SKA RF, as well as the relationship between IMT and ASP in CCA, does not exclude the role of other RFs, leading to atherosclerosis of the arterial wall. Non-specific inflammation in different layers of the vascular wall with the formation of SCA and/or vascular ageing may be the unifying etiopathogenetic factor

    Circadian profile and chrono-structure of blood pressure in patients with arterial hypertension: desynchronosis as a risk factor in Far North shift workers

    Aim. To study circadian profile (CP) and chrono-structure of blood pressure (BP) in patients with arterial hypertension (AH) and to assess the role of desynchronosis as an AH risk factor among Far North shift workers.Material and methods. CP and chrono-structure of BP were analysed in 393 men, aged 20-59 years. The main group (MG) included 177 AH patients – Far North shift workers. The comparison group (ComG) included 158 AH patients - Tyumen City residents. The control group (ConG) included 43 healthy Far North workers and 15 Tyumen City residents.Results. In Far North patients with AH, BP CP was characterised by desynchronosis and hypersympathicotonia, manifested in “flattened” BP CP curve, increased night-time hemodynamic load, elevated mean 24-hour diastolic BP (DBP) and reduced mean 24-hour systolic BP (SBP), phase discordance between BP CP and heart rate (HR), increased circadian heart rate variability, increased mean 24-hour HR, and significant differences between office and 24-hour levels of SBP and DBP. In the ComG and ConG, disturbed chrono-structure of BP and progressing endogenous and exogenous desynchronosis.Conclusion. Desynchronosis, as a manifestation of disturbed neuro-humoral regulation, could play an important role in AH development among patients adapting to extreme conditions of the Far North
