Objective To investigate the current status of social participation among middle-aged and young patients after pacemaker implantation, and to analyze its influencing factors, so as to provide a reference for implementing targeted nursing interventions to improve patients′ level of social participation.Methods A total of 320 middle-aged and young patients after pacemaker implantation were followed-up and selected in the cardiology outpatient department of a tertiary hospital in Zhengzhou by using convenience sampling.Six month after the patient′s pacemaker implantation, they were investigated by using a general information questionnaire, the Impact on Participation and Autonomy Questionnaire （IPA）, Chinese version of the Tampa Scale for Kinesiophobia Heart （TSK-Heart), the Brief Illness Perception Questionnaire (BIPQ), and the Perceived Social Support Scale (PSSS).Results The score of the IPA among participants was (58.92±5.72).The IPA score was positively correlated with the TSK-Heart score and the BIPQ score (both P＜0.05), and it was negatively correlated with PSSS score (P＜0.05).The multiple linear regression analysis results showed that, educational background, living conditions, heart function grading, exercise fear, disease perception, and perceived social support were the influencing factors of social participation among middle-aged and young patients after pacemaker implantation, accounting for 30.3% of the total variance.Conclusion The social participation in middle-aged and young patients after pacemaker implantation needs to be improved.Medical staff should pay more attention to those patients with low educational levels, living alone and poor cardiac function, help them alleviate fear of exercise, provide them with sufficient medical support, decrease their negative perception of disease, so as to improve their level of social participation.
