Prevalence of ischemic heart disease, its main risk factors and efficacy of long-term multifactorial prevention at enterprises in some regions of the Russian Federation

Abstract

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. 14000 male and 20969 female volunteers were observed in organized groups in three Russian cities (Cheboksary, Pskov, St-Petersburg). 8984 males and 14515 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.
