Abstract:OBJECTIVE To investigate the status of the main caregiver burden of patients after myocardial infarction and its influencing factors. METHODS A total of 130 primary caregivers from patients with myocardial infarction in Zhengzhou from January 2016 to December 2017 were enrolled. The survey was conducted in the form of a questionnaire survey. The main survey tools were the General Survey Questionnaire, the Daily Living Ability Scale, the Social Support Rating Scale, and the Zarlt Caregiver Burden Scale. Univariate analysis was performed using t test or F test, and multivariate analysis was performed using logistic analysis. RESULTS Univariate analysis showed gender, age, disease duration, and daily living ability; gender, age, education level, occupational status, daily care time, and social support in the general information of the caregiver had a significant impact on the caregiver burden (P<0.05). Multivariate analysis showed that the course of the disease, the patient’s daily living ability, the caregiver’s educational level, the caregiver’s occupational status, the daily care of the patient and the caregiver’s social support were all independent factors affecting the caregiver’s burden (P<0.05). CONCLUSION The main caregiver burden and course of the patients after myocardial infarction, the patient’s daily living ability, the caregiver’s educational level, the caregiver’s occupational status, the daily care of the patient’s time and the caregiver’s social support were all related to the caregiver’s burden. The nursing staff could conduct psychological intervention and social support were provided to the main caregivers to ease their stress and improve the quality of caregivers.
