Objective  To analyze the influencing factors of knowledge, belief and behavior of rehabilitation exercise in patients with chronic heart failure (CHF).

Methods  A total of 300 patients with CHF were selected as study objects by simple random sampling method, and the Rehabilitation Exercise Questionnaire, Self-perceived Burden Scale and Exercise Fear Scale for Patients with Heart Disease were used respectively to evaluate the conditions of knowledge, belief and behavior of rehabilitation exercise, self-perceived burden and exercise fear level in patients with CHF.

Results  In the evaluation of knowledge, belief and behavior of rehabilitation exercise in the 300 patients with CHF, the score of motor behavior dimension was the highest while the score of motor knowledge dimension was the lowest(20.64±3.14), (11.62±2.36); in the evaluation of Self-perceived Burden Scale, the score of physical burden dimension was the highest while the score of economic burden dimension was the lowest(15.32±3.35), (3.21±0.93); in the evaluation of Exercise Fear Scale, the score of risk perception dimension was the highest while the score of dysfunction dimension was the lowest(12.96±2.11), (9.85±2.12). The results of univariate analysis showed that gender, education level, income and having other chronic diseases were the influencing factors of knowledge, belief and behavior of rehabilitation exercise in CHF patients (P < 0.01). Multiple linear regression analysis showed that gender, education level, self-perceived burden and exercise fear were the main factors affecting the knowledge, belief and behavior of rehabilitation exercise in patients with CHF (P < 0.01).

Conclusion  The knowledge, belief and behavior of rehabilitation exercise is at a low level in CHF patients, and the level of self-perceived burden, gender, educational level and exercise fear are the main factors affecting knowledge, belief and behavior of rehabilitation exercise. In the process of clinical practice, we should actively identify patients with low level of knowledge, belief and behavior, formulate a reasonableand scientific rehabilitation program, and improve the prognosis of patients.
