Medication Training Via Ignite Based on Roy Model in Heart Failure: Medication Adherence and Symptom Management

The goal of this clinical trial is to learn if a structured medication training program can help people with heart failure better manage their condition. The program is based on the Roy Adaptation Model and is designed to support how people adjust to their illness. The main questions it aims to answer are: Does the training program improve heart failure symptoms? Does the training program help participants take their medications as prescribed? Researchers will compare a training program group to a control group receiving standard care to see if the program is effective. Participants will: Be randomly assigned to either a training program group or a control group Receive the training program through WhatsApp after hospital discharge or receive standard discharge education Be followed for 12 weeks Complete questionnaires at the start of the study, at 4 weeks, and at 12 weeks

THE RELATIONSHIP BETWEEN CARDIAC RESYNCHRONİZATION THERAPY RESPONSE IN HEART FAILURE PATIENTS AND YKL-40 LEVELS

Patients diagnosed with heart failure at our clinic who routinely undergo CRT implantation will be included in the study. This decision is independent of the study. In patients included in the study, after routine placement of a coronary sinus catheter, 2 cc of blood will be drawn from this catheter without performing any additional invasive procedures on the patient. Additionally, one peripheral blood sample will be collected from the patient's routinely accessed antebrachial vein. The blood samples will be centrifuged at 4000 rpm (revolutions per minute) for 10 minutes to separate the serum and stored at -80 °C until analyzed. The demographic, clinical, laboratory, electrocardiographic, and echocardiographic data of these patients will be recorded. At the 6-month follow-up clinic visit after discharge, routine heart failure parameters, routine echocardiographic data, and routine ECG recordings will be obtained. The procedures to be performed after discharge are routine for patients who have undergone CRT implantation at our clinic, and no additional follow-up or tests will be performed for this study. After all data are recorded, statistical evaluation will be performed. Data will be reviewed through the ENLİL HBYS system. The best criteria for determining CRT response have not been clearly established. Many studies have been conducted to predict CRT response in advance. A review of the literature shows that YKL-40 levels in the blood are associated with cardiovascular diseases, but no study in the literature has shown the relationship between YKL-40 levels and CRT implantation in patients.
