Abstract. Low treatment adherence is a pressing issue that significantly impacts the life quality (LQ) of multimorbid patients. The aim: to assess LQ and treatment adherence in elderly outpatients with chronic heart failure (CHF). Material and methods. The study included 90 outpatients – 32 male and 58 female individuals (median age 74 [67; 84] years). They were divided into two groups based on the presence of CHF: patients with this condition (n = 53) and those without it (n = 37). Additional analysis was made in the age subgroups 60–74 and ≥ 75 years. Various scales and questionnaires were used for clinical estimation of patients, and the Short Form-36 (SF-36) questionnaire was used to assess LQ. Treatment adherence was determined using the National Society for Evidence-Based Pharmacotherapy (NSEBP) scale. Results. Participants with CHF showed a more pronounced decrease in LQ indexes comparatively to patients without CHF. The most significant differences were found in SF-36 questionnaire scales reflecting the physical component of health, the total index of which was lower in the CHF group across all age subgroups. That indicates the leading role of functional limitations in the decline of LQ in this patient category (p <0.05). Logistic regression analysis revealed that deterioration in functional mobility, assessed by the time it takes to complete the “Get-up and Go” test, was associated with a reduced probability of full adherence to medication therapy (odds ratio 0.795; 95% confidence interval: 0.647–0.976; p = 0.029). Conclusion. Elderly and senile patients with CHF have a more pronounced decline in LQ parameters comparatively to patients without CHF, primarily due to physical functioning deterioration. CHF is also associated with a higher prevalence of geriatric disorders and reduced functional mobility. The obtained data indicate a possible role of functional limitations in the formation of treatment adherence and highlight the need for a comprehensive assessment of geriatric factors in the management of older patients having CHF.
