This study looks at how giving heart surgery patients information before their operation affects their anxiety (feeling worried) and how well they follow treatment rules. The study involves watching a 12-minute video twice before surgery, in addition to getting regular information. This is called the "experimental group," while the "comparison group" gets the usual information only. The aim is to see if the video helps reduce anxiety and improves cooperation during recovery in the ICU (Intensive Care Unit).
- **Participation involves watching a 12-minute video twice before surgery.**
- **The study is open to first-time heart surgery patients who speak Thai.**
- **Patients with a mental test score below 8 or needing urgent care cannot participate.**
Participants will be asked about their anxiety levels before and after the video and 48 hours post-surgery. If interested, patients can contact researchers or be approached by nurses for participation. A signed consent is needed for participation, and the process will take place between 6:00-8:00 p.m. after pre-surgery preparations.
