Prevalence of ischemic heart disease. Its relation with main risk factors and efficiency of long-term multifactorial prevention in organized groups of employees

Aim. To study the prevalence of ischemic heart disease (IHD) and its variou s 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 contr ol group. 8326 males and 13116 females volunteers were included into the gr oups of active prevention and observation. Results. Risk factor correction produced a significant decrease in both sys tolic and diastolic BP mean levels, prevalence of ECG abnormalities togethe r with smoking habits occurrence, overweight and their combination. The gen eral mortality rate, IHD and stroke mortality were significantly less in th e 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 o f IHD, risk factors increased general mortality rates and cardiovascular mo rtality rates in both groups. The multifactorial prevention of IHD contribu ted to a decline in general mortality rates and cardiovascular mortality ra te.
