P5679Adherence to lifestyle therapy in patient with chronic heart failure and comorbidity

Abstract

Introduction: Low adherence to treatment is a widely extended problem among patients with chronic heart failure (CHF). Besides medical treatment, lifestyle modifications improves quality of life and prognosis of patients with cardiovascular diseases. However, influence of comorbidity on adherence to lifestyle therapy in patients with CHF have not been studied yet. The aim of this study was to investigate awareness and adherence to lifestyle therapy in patient with CHF and comorbidity. Method(s): 203 patients with CHF (130 males and 73 females, mean age was 62+/-10 years) were studied. CHF was defined according to ESC Guidelines for the diagnosis and treatment of acute and chronic heart failure, 2016. The main causes of CHF were coronary heart disease and arterial hypertension. Charlson comorbidity index was calculated. Awareness of lifestyle modifications was determined using a questionnaire developed in our clinic and used in previous scientific studies. Adherence to lifestyle therapy was considered satisfactory when patients performed at least 80% of the recommendations. Quality of life was estimated using SF-36 Health Status Survey. Patients were followed up for 1 year. Result(s): The awareness about lifestyle modifications in patients with CHF ranged from 38.9% (daily control of body weight) to 87.2% (reduced intake ofdietary sodium). 33 (16.3%) patients had self-control diaries. Only half of the patients, who known about lifestyle modifications, performed medical recommendations. Adherence to lifestyle therapy was from 7.9% (daily weight control) to 37.9% (reduced intake ofdietary sodium). The main types of physical activity in patients with CHF were walking - 49 (22.7%) and morning exercises - 31 (15.3%).Patients with CHF, engaging in physical activity, had higher rates quality of life according to the scales of the physical component of health: physical functioning (r=0.30, p=0.003) and physical-role functioning (r=0.31; p=0.001); and on the scale of the psychological component of health: emotional-role function (r=0.30, p=0.002).Only 37 (18.2%) patients were full adherence to lifestyle therapy. Age adjusted Charlson comorbidity index was 5.0+/-2.1 scores. There were not differences in adherence to lifestyle therapy in patients with CHF, depending on the level of comorbidity. Conclusion(s): Only every fifth patient with CHF was adherence to lifestyle therapy despite of the level of awareness about lifestyle modifications and comorbidity.
