Aim To compare Russian versions of the scales for assessment of self-care ability in patients with chronic heart failure (CHF), European Heart Failure Self-Care Behavior Scale (EHFScBS_9) and The Self-Сare of Heart Failure Index (SCHFI, version 6.2).Materials and methods Assessment of the self-care ability was performed with Russian versions of EHFScBS_9 and SCHFI (version 6.2) scales in 130 patients with NYHA functional class II-IV CHF primarily of ischemic origin (78.5 %). Mean age of patients was 63.2±9.6 years; most of the patients were men (n=92; 70.8 %). Patients were managed in accordance with effective guidelines ESC / HFA 2016 and Russian guidelines 2018.Results Along with an increase in SСHFI scores, a decrease in EHFScBS_9 scores was observed (r= -0.31, p<0.001). The patients participating in the study showed a low self-care ability at baseline according to results of both scales.Conclusion The presence of certain differences between the study scales does not exclude a possibility of using them alone or together for more detailed assessment of the self-care ability.
