Evaluation of the Effect of Animated Video-Assisted Nutrition Education on Heart Failure Patients

Evaluation of the Effect of Animated Video-Assisted Nutrition Education on Nutritional Behaviors, Symptom Severity, and Quality of Life in Heart Failure Patients

This randomized controlled trial aims to evaluate the effect of animation video-supported nutrition education on dietary behaviors, symptom severity, and quality of life in patients with heart failure. A total of 70 patients aged 45-60 years with NYHA class II or III heart failure will be recruited at Tokat Gaziosmanpaşa University Research and Application Hospital Cardiology Clinic. Participants will be randomly assigned to an intervention group, which will receive video-supported nutrition education, or a control group, which will receive standard care. Outcomes will be assessed using the Heart Failure Dietary Behavior Scale, Heart Failure Symptom Status Scale, and Minnesota Living with Heart Failure Questionnaire at baseline, 1 month, 3 months, and 6 months.

This study investigates the effect of animation video-supported nutrition education on dietary behaviors, symptom severity, and quality of life in patients with heart failure (HF). The study will be conducted at Tokat Gaziosmanpaşa University Research and Application Hospital Cardiology Clinic from July 2025 to December 2025. A total of 70 patients aged 45-60 years with NYHA class II or III HF will be included. Patients meeting the inclusion criteria and willing to participate will be randomly assigned to the intervention or control group using a computer-based simple randomization method.

The intervention group will receive a structured nutrition education program delivered through animation videos developed based on clinical guidelines, focusing on balanced nutrition, sodium restriction, sugar and cholesterol control, and fluid retention prevention. Videos will illustrate key concepts using the "5W1H and Symptom" (What, Where, How, When, Why, Symptom) principle. Baseline assessments will include the Heart Failure Dietary Behavior Scale, Heart Failure Symptom Status Scale, Minnesota Living with Heart Failure Questionnaire, and a demographic form. Follow-up assessments will be conducted at 1 month, 3 months, and 6 months.

The control group will receive standard care, including verbal advice from cardiologists. After completion of the study, control group patients will also have access to the animation video education. Data will be analyzed using SPSS v25 with appropriate statistical tests, and linear mixed-effects models will be applied to evaluate group, time, and group-time interaction effects.
