Chronic heart failure is a complex, usually progressive clinical syndrome that, regardless of structural or functional heart disease, is characterized by the inability of the heart to receive or displace blood and thus meet the metabolic needs of the organism (1). Heart failure (HF) most often occurs as a result of a previous and late treatment of myocardial infarction, uncontrolled hypertension, heart valve disease, or myocardial disease. Patient education is an important component of HF care and should be provided through effective and well-assessed strategies. Numerous studies in patients with HF have shown a need for education (2). Almost all nursing diagnoses involve educating a patient or family member in a health care plan through nursing interventions (3). The nurse spends the most time with the patient and educates him about the importance of taking therapy, lifestyle changes - weight loss, limiting fluid intake, reducing salt in the diet, regulating blood pressure and blood glucose, and managing stress. Relapses are common due to a frivolous understanding of the disease and non-compliance with health instructions. Education about the disease helps to raise self-confidence, encouraging patients to become aware of their disease, to do everything to slow down the course of HF and thus reduce the number of hospitalizations, and to improve the quality of life.
