Result: The duration of Warfarin averaged 2.6±274 months, and 42.7% of participants remembered their blood coagulation value (INR) and 80.5% of patients were warfarin-educated (Individual education, group education) but 42.7% of patients had side effects. The mean score for drug-related Knowledge was 9.7 points out pf a possible 13 points. medication adherence was 6.6 points out of a possible 8 points, sick role behavior was 6.6 points out of a possible 18 points. Conclusion: Marriage, activity level (NYHA 1.2), and knowledge factors influenced sick role behavior. The result indicates that there is a need to enhance the level of drug-related knowledge to increase positive behavior as part of the sick role of these patients. Sick role behavior explained factor was 25.1%. As a result, it is necessary to develop programs that can strengthen family mediation and improve heart functioning performance in warfarin-related education.
