Abstract: Objective To investigate the factors influencing the implementation status of cardiac rehabilitation by cardiovascular nurses. Methods A self-designed questionnaire titled "Survey on Factors Influencing the Implementation of Cardiac Rehabilitation by Cardiovascular Nurses" was used to survey cardiovascular nurses from tertiary hospitals in Beijing, Anhui Province, and other regions through convenience sampling. Results A total of 655 questionnaires were distributed, with 548 valid responses, yielding an effective response rate of 83.66%. The main promoting factors for nurses in cardiology departments to implement cardiac rehabilitation were nurses' experience in guiding patients through cardiac rehabilitation, the establishment of dedicated cardiac rehabilitation centers in hospitals, and the inclusion score of cardiac rehabilitation in national medical insurance of (4.32±0.79) points; the main obstacles were patients' lack of understanding of cardiac rehabilitation (3.03±1.04) points, the high turnover rate in the department (4.21±0.79) points, and incomplete laws and regulations related to cardiac rehabilitation (3.56±0.88) points. Conclusion The implementation of cardiac rehabilitation by nurses in cardiology departments is related to factors such as the nurses, patients, hospitals, and policies. Clinical importance should be given to these factors, and corresponding measures should be taken to promote the implementation of cardiac rehabilitation.
