Hearth Failure With Reduced Ejection Fraction (HFrEF)

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
