[Prevalence of arterial hypertension and efficacy of long-term multifactor prophylaxis in some regions of Russia].

AIM: To study prevalence of arterial hypertension (AH) in relation to gender, age, profession, risk factors (RF), RF combination; efficacy of active long-term multifactor prevention among the employees of industrial enterprises in some regions of Russia. MATERIAL AND METHODS: 14000 males and 20969 females from industrial enterprises of Cheboksary, Pskov, St-Petersburg were examined. 8974 males and 14515 females worked at enterprises of active intervention (EAI) while 1848 males and 1643 females were employed at comparison enterprises. RESULTS: Correction of RF conducted at six EAI reduced a mean level of systolic blood pressure (SBP) and diastolic blood pressure (DBP), frequency and intensity of smoking, overweight and cases of RF combination, improved ECG parameters, wellbeing of hypertensive patients, increased number of examinees free of risk factors, decreased number of days of temporary disability. Among EAI employees overall mortality, ishemic heart disease mortality and cerebrovascular disorders fell. CONCLUSION: Five- and 10-year active multifactor office prophylaxis resulted in reduction of the rate and intensity of RF, number of temporary disability days by 48%. Arterial hypertention, combination of RF in healthy and hypertensive subjects at the start of the trial significantly promoted high all-causes and cardiovascular mortality at all enterprises studied. Active multifactor prophylaxis reduced those mortalities significantly.

AIM: To study prevalence of ischemic heart disease (IHD) and its various clinical forms depending on sex, age, profession including risk factors (RF) and their combination and efficiency of long-term multifactorial active prevention programs at enterprises in several regions of the Russian Federation. MATERIAL AND METHODS: 14,000 male and 20,969 female volunteers were observed in organized groups in three Russian cities (Cheboksary, Pskov, St-Petersburg). 8984 males and 14,515 females entered seven groups of outpatient follow-up and active long-term multifactorial prevention during 5-10 years. RESULTS: Risk factor correction produced a significant decrease in mean systolic and diastolic blood pressure, frequency and intensity of smoking, overweight, improved ECG parameters, increased number of the examinees free of risk factors; state of IHD patients improved. Overall mortality, IHD and stroke mortality, number of temporary disability days were significantly less in the prevention group. CONCLUSION: Active multifactorial "in office" prevention for 5 to 10 years reduced RF prevalence and intensity, quantity of days at sick-leave fell by 48.5%. The presence of IHD and risk factors in both groups increased overall mortality rates and cardiovascular (IHD and stroke) mortality rates at the beginning of the study. The multifactorial prevention of IHD and risk factors resulted in a significant reduction of overall mortality rates as well as cardiovascular mortality rates in groups of active prevention.

AIM: To study prevalence of cardiovascular disease risk factors (CRF) in relation to sex, age, occupation as well as efficiency of active long-term multifactorial prophylaxis in the groups of active intervention (AI) and observation. MATERIAL AND METHODS: The comparison group consisted of 1848 male and 1643 female volunteers. 8326 males and 13,116 females entered the group of active intervention and observation. RESULTS: Risk factors correction led to lowering of mean systolic and diastolic arterial pressure, smoking intensity, overweight, to improvement of wellbeing of cardiovascular patients. The number of examinees with several risk factors decreased while those free of risk factors increased. There was also a reduction in the number of days of temporary disability. In AI group total mortality, coronary heart disease and cerebral event mortality fell manifold. CONCLUSION: Five- and ten-year active multifactorial "in-office" prophylaxis decreased frequency and intensity of risk factors. Lowering of cardiovascular disease incidence was associated with a 44.4% decrease in the number of days on sick-leave. The presence of cardiovascular diseases, combination of risk factors in healthy subjects and in cardiovascular patients in the beginning of the study significantly increased total mortality, cardiovascular mortality in comparison and active intervention groups. Active multifactor prophylaxis in persons with risk factors and cardiovascular diseases, especially in combination with risk factors, in the beginning of the study reduced total mortality and mortality of cardiovascular disease in active intervention.

AIM: To study the prevalence of ischemic heart disease (IHD) and its various clinical forms depending on both sexes, age, profession, risk factors and efficiency of active prevention programs. MATERIAL AND METHODS: 1848 males and 1643 females were inspected as a control group. 8326 males and 13,116 females volunteers were included into the groups of active prevention and observation. RESULTS: Risk factor correction produced a significant decrease in both systolic and diastolic BP mean levels, prevalence of ECG abnormalities together with smoking habits occurrence, overweight and their combination. The general mortality rate, IHD and stroke mortality were significantly less in the group of prevention as well as the number of days of temporary disability. CONCLUSION: Primary and secondary "in office" prevention for 5 to 10 years diminished the prevalence of risk factors and events of IHD. The presence of IHD, risk factors increased general mortality rates and cardiovascular mortality rates in both groups. The multifactorial prevention of IHD contributed to a decline in general mortality rates and cardiovascular mortality rate.

AIM: Evaluation of cardiovascular diseases (CVD) prevalence and their dynamics after active prevention program. MATERIALS AND METHODS: 1382 male and 155 female volunteers were included into the group of active prevention in their office. 1024 males and 776 females with natural history were compared as a control group. 5-year follow-up was performed in 543 males and 569 females in comparison with 97 males and 119 females. 10-year follow-up covered 82 males and 191 females from the active prevention group and 178 males and 118 females from the referent group. RESULTS: The risk factor correction has resulted in a significant decrease in both systolic and diastolic BP mean levels, prevalence of ECG abnormalities, smoking habits, overweight and combination of the risk factors, general mortality rate, CHD and stroke mortality, number of days of temporary disability. CONCLUSION: The primary and secondary "in office" prevention for 5 to 10 years diminishes the prevalence of the risk factors. The temporary and primary disability rates were connected with the presence of CVD. CVD, in line with other risk factors, significantly increased cardiovascular and general mortality rates.

AIM: To evaluate trends in arterial hypertension (AH) and other risk factors and their changes after active prevention program. MATERIAL AND METHODS: 1382 male and 1555 female volunteers were included into the group of active prevention at the workplace vs 1024 male and 776 female controls. 5-year follow-up covered 543 males and 569 females from the prevention group against 97 male and 119 female controls. 10-year follow-up covered 82 males and 191 females, 178 males and 118 females, respectively. RESULTS: Risk factor correction produced a significant decrease in both systolic and diastolic BP levels, prevalence of ECG deteriorations, smoking habits occurrence, overweight. Overall mortality rate, CHD and stroke mortality were significantly less frequent in the prevention group. This group had also less days of temporary disability. CONCLUSION: The primary and secondary "in office" prevention for 5 to 10 years diminishes prevalence of risk factors. The temporary disability rate depends on the presence of arterial hypertension. The latter together with the other main risk facts significantly influences cardiovascular and general mortality rates.

[The prevalence of cardiovascular diseases among the workers and employees of organized collectives based on cardiological screening data]. / Rasprostranennost' serdechno-sosudistykh zabolevanii sredi rabochikh i sluzhashchikh organizovannykh kollektivov po dannym kardiologicheskogo skrininga.

Altogether 90.2 thousand workers of 33 enterprises of the cities and villages were examined. Of these, men (mean age 41.1 +/- 1.1 years) accounted for 39.2%. Use was made of an automated system for mass cardiological screening and dispensary observation made over time of the workers and employees of the organized bodies by computer EC, CM and IBM PC XT/AT. Different cardiological diseases were revealed in 38.4% of the examined. Out of the total number of the patients, 44.5% were diagnosed to have arterial hypertension (AH) whereas 18.6% coronary heart disease (CHD). CHD was widely prevalent in the working middle-aged and elderly men and women. Angina pectoris of effort appeared to be most frequently occurring form of CHD, accounting for 70.4% of the total number of CHD patients. Myocardial infarction was discovered in 0.9% of men and 0.3% of women. AH was identified in 40.8% of CHD patients, whereas 38% demonstrated borderline AH. Therefore, associated CHD and elevated blood pressure was recorded in 78.8% of the patients. A relationship was established between the prevalence and incidence of cardiovascular diseases and sex and age.
