The retrieval time limit was from the establishment of the database to October 2019. Four researchers evaluated the quality of the literature, and extracted evidence from the literature that met the quality standards.Results:A total of 5 articles were included, including 2 guidelines, 2 expert consensus, 1 systematic reviews,3 randomized controlled trials. The best evidence included evaluation of discharge readiness, education of knowledge and skills to patients and caregivers, improvement of self-efficacy of patients and caregivers in disease management, and assurance of social support and health resources for patients and caregivers after discharge.Conclusion:It is suggested that in clinical practice, medical personnel should use the discharge readiness assessment tool to comprehensively evaluate patients after PCI, carry out programmed health education, improve patients' self-efficacy in disease management, and ensure social and medical support for patients and caregivers after discharge as much as possible.
