Factors predicting preoperative anxiety among adult patients undergoing cardiac surgery in China: A cross-sectional study

Preoperative anxiety in adult patients undergoing elective cardiac surgery is significantly influenced by factors such as fear of surgery, preoperative sleep quality, and perceived social support. Nurses can implement targeted interventions to reduce preoperative anxiety. These interventions may include addressing the fear of surgery through health education and psychological counseling. Furthermore, improving the hospital environment to promote a calm and quiet atmosphere can enhance sleep quality. Encouraging social support to help patients build confidence in the success of their surgery and their ability to recover is also recommended.
