HEART RATE AND ITS ASSOCIATION WITH THE MAIN RISK FACTORS IN THE POPULATION OF MEN AND WOMEN OF WORKING AGE

Aim. To study the association of heart rate (HR) with the health parameters obtained in the ESSE-RF study.

Material and methods. The data of the multicenter epidemiological study of ESSE-RF were used in the work. 8,343 men and 13,531 women aged 25-64 years were examined. The response to the survey was about 80%. The analysis is performed depending on the elevated heart rate. Education, place of residence, region, lipid profile, levels of C-reactive protein (CRP) and glucose, history of diabetes, anxiety and depression, elevated blood pressure were analyzed as factors possibly associated with increased heart rate. Epidemiological diagnosis of ischemic heart disease (IHD) was established using the Rose questionnaire, an electrocardiogram analysis, followed by the Minnesota code coding.

Results. Almost every fifth inhabitant had a pulse rate of more than 80 beats/min. No significant difference was found between the sexes. The increase in heart rate in men, starting in the age group 25-34 years to 45-54, and in women only up to 35-44 years with subsequent reduction in men and women was found. The prevalence of increased heart rate varies from region to region. The highest heart rate in men is recorded in Orenburg (33.1%), Ossetia (Alania) and Volgograd (29.7% and 27.6%, respectively), in women – in Vladivostok (37.4%), and the lowest heart rate in both gender groups

– in Samara (9.4% for men and 8.1% for women). Increase in heart rate in men with secondary education [odds ratio (OR) 1.24; 95% confidence interval (CI) 1.10-1.40], smokers and quitters (OR 1.90, 95% CI 1.63-2.27), who did not drink alcohol during the last year (OR 1.18, 95% CI 1.021.37), living in rural areas (OR 1.22, 95% CI 1.04-1.42), who are obese (OR 1.27, 95% CI, 1.101.45), having elevated blood pressure (OR 2.24, 95% CI 1.88-2.67), elevated levels of triglycerides, glucose and CRP was found after correction for age, region and all indicators included in the analysis (multidimensional model). The heart rate >80 beats/min was found significantly less often in people with history of myocardial infarction. A different model was found in women, it included, like in men, living in the village, elevated levels of blood pressure, triglycerides, glucose and CRP, but not education, smoking and alcohol consumption, obesity. Anxiety, low level of high-density lipoproteins and history of diabetes mellitus were also in the model in women.

Сonclusion. Significant associations between increased heart rate and metabolic risk factors, inflammation and residence in the village are found.
