Objective:To investigate the cognitive status of fatigue among patients with coronary heart disease (CHD) in the community and analyze its influencing factors.Methods:From May to July 2020, a total of 250 patients with CHD in the community were selected as the research objects by multi-stage sampling method. The general information questionnaire and Fatigue Cognition Questionnaire for Patients with CHD were used for investigation. Multiple linear regression analysis was used to analyze the influencing factors. A total of 250 questionnaires were distributed and 245 were effectively recovered.Results:The total score of fatigue cognition of 245 patients with CHD in the community was 6 (4, 7) . Univariate analysis showed that there were statistically significant differences in the total scores of fatigue cognition among community CHD patients with different education level, duration of disease, grading of cardiac function, whether pay attention to fatigue knowledge, number of combined chronic diseases and treatment methods ( P<0.05) . Multiple linear regression analysis showed that education level, duration of disease, whether pay attention to fatigue knowledge, number of combined chronic diseases and treatment methods were the main influencing factors on fatigue cognition of CHD patients in the community ( P<0.05) . Conclusions:The cognition of patients with CHD in the community on fatigue needs to be improved, and community medical workers should take corresponding measures to increase the attention and active response of patients with CHD to fatigue.
