Objective: to assess the presence and nature of age-dependent changes in the predictors used for risk stratification of patients with chronic heart failure (CHF). Material and Methods. We perform an analysis of predictive models of CHF, including a comparative assessment of predictors and age of patients. At the second stage, age-dependent changes in the most commonly predictors of CHF were characterized. The study included hospitalized patients with CHF (36-94 years, n=2764). Results. We analyzed 275 prognostic models based on results of large studies (n=36062±5814). The mean age of the patients involved was 68.9±7.6 years. The major predictors included the patient's age and/or potentially age-dependent parameters: hemoglobin, creatinine, RDW, LVEF, SBP and NT-proBNP. In the study sample all of these parameters correlated with the age of the patients with the maximum correlation strength of "NT-proBNP — age" (R=0.57; p<0.05) and "hemoglobin level — age" (-0.57; p<0.05). Conclusion. The prevalence of mature and elderly patients in the populations of studies used to develop the majority of risk instruments for heart failure is revealed. The age-dependent nature of the predictors used in the risk of heart failure is established (hemoglobin, creatinine, RDW, LVEF, SBP and NT-proBNP). The simultaneous use of age and age-dependent parameters as predictors when creating risk-assessment tools may be considered as one of the reasons for the unsatisfactory quality of risk stratification in CHF, including elderly and senile patients.
