Self-Care and Compliance with Medication and Their Relationship to the Quality of Life of Patients with Heart Failure.

Introduction: Heart failure is a major health problem, often accompanied by limited physical activity and severe effects in various areas of patient quality of life. Self-care, as well as compliance with medication, can further contribute to clinical stability and improved patient outcomes.

Purpose: The purpose of this chapter is to assess the effect of self-care and compliance with medication, on the quality of life of patients with heart failure.

Method: The research sample consisted of 67 patients diagnosed with heart failure who visited the cardiology outpatient clinic of a general hospital in the capital of Greece. The assessment of self-care behavior was performed by the scale EHFScBS and SCHFI v.6, the Morsiky Green Levine Adherence Scale (MAQ) was used for the evaluation of adherence to medical treatment, while for the evaluation of the quality of life the questionnaire MLWHFQ was used.

Results: The multifactorial linear regression analysis showed that age, compliance with medication and scoring in the dimension "Self-care confidence" relates independently to the overall quality-of-life scale rating. In particular, participants over 80 had a significantly higher score, that is, worse quality of life, compared to those under the age of 70 (p < 0.001), while participants with low compliance with treatment had a significantly worse quality of life compared to participants with high compliance (p < 0.001). It has been noticed that the better self-care they had and the higher compliance with their medication, their quality of life was better.

Conclusion: Self-care behavior and adherence to medical treatment of patients with heart failure are related to their quality of life. Age, educational level, and "Self-care confidence" are factors that influence self-care behavior, compliance with medication, and quality of life. In-depth patient information on the need for adherence to therapeutic guidelines may help to reduce pharmaceutical costs and maximize the therapeutic effect. For this reason, health professionals treating these patients should take into account all the factors that negatively affect their quality of life and treat them with the appropriate interventions.
