1 Государственный научно-исследовательский центр профилактической медицины 101990, Москва, Петроверигский пер., 10 2 Медико-санитарная часть № 170 Федерального медико-биологического агентства РФ 141071, Московская обл., г. Королев, ул. Ленина, д. 2Цель. Определить частоту и маркеры скрытой артериальной гипертонии (АГ) и скрытой неэффективности лечения (СНЛ) АГ у работников закрытого промышленно-го предприятия в рамках ежегодного профилактического осмотра. Материал и методы. В одномоментном когортном исследование работников крупного промышленного предприятия, занятых на работах с вредными и/или опас-ными условиями труда (n=477; средний возраст 53,2±5,5 года) отобраны лица (n=185) с нормальным офисным АД <140 и <90 мм рт. Aim. To study the rate and characters of masked arterial hypertension (HT) and masked ineffectiveness of HT treatment in industrial workers within annual preventive examination. Material and methods. Workers (n=185) with normal office blood pressure (BP) <140 and <90 mm Hg were enrolled into cross-cohort study of industrial workers of large enterprise engaged in activity with harmful and/or dangerous conditions (n=477; mean age 53.2±5.5 years). Standard survey, anthropometry, ambulatory BP monitoring (ABPM), blood chemistry, electrocardiography, and echocardiography were performed. Criteria of masked HT and masked HT in treated subjects were the level of office BP <140 and <90 mm Hg in combination with mean BP during the operational period ≥135 and/or ≥85 mmHg. Patient characters significantly associated with this ratio of office BP and BP during the operational period were considered as features of isolated increase in ambulatory BP level.Results. The rate of masked HT among workers with normal office BP was 10.8%, and masked HT among treated subjects was 34.6%. Workers with masked HT, in contrast to the normotensive workers according to the office BP and ABPM measurements, had a higher left ventricular mass index (in males 129. .5 mmol/l, respectively, p<0.05), more prominent left ventricular hypertrophy, lower incidence of ischemic heart disease, but higher number of persons taking ACE inhibitors. Occupation and work features were not characters of the masked HT and masked ineffectiveness of HT treatment. Conclusion. Masked HT and masked HT in treated subjects (masked ineffectiveness of HT treatment) can occur in almost a half of industrial workers with normal office BP. Ambulatory BP measurement methods, especially ABPM, as well as standard risk factors detection are necessary for early revealing of HT phenotypes during preventive examination.

Based on scientific literature and own data, the article discusses the problem of hypertensive heart disease in real outpatient practice and especially in conducting preventive examinations in the working population. It is shown that the use of modern diagnostic methods, in particular electrocardiography with dopplerography, including pulse-wave tissue mode, should be an integral study included in the professional examination, as well as medical examination, which covers an increasing number of the population of our country. Echocardiography should be performed to clarify the cardiovascular risk and confirm the electrocardiographic diagnosis of left ventricular hypertrophy (LVH), left atrial dilatation, or suspected heart diseases (coronary heart disease, atrial fibrillation, other rhythm disorders). It has been shown that concentric LVH is the strongest predictor of an increased risk of heart failure, although the degree of LVH is not always directly related to the degree of hypertension and the duration of the disease.
