Objective To investigate the feasibility and effectiveness of self-management scheme for heart failure patients based on the theory of knowledge, belief and action combined with Rosenthal effect.

Methods A total of 94 patients with heart failure were randomly divided into the control group and observation group by random number table method.The control group received the routine nursing intervention, the observation group was implemented by self-management plan based on knowledge, belief, and behavior theory combined with Rosenthal effect on the basis of the control group.The self-management scores, health behavior scores, quality of life scores and heart function related indicators were compared between the two groups.

Results After intervention, the self-management scores in the two groups were significantly improved compared with that before intervention, and the improvement of self-management score in the observation group was higher than that in the control group(P < 0.05).After intervention, the health behavior scores in the two groups were significantly improved compared with that before intervention, and the improvement of the health behavior score in the observation group was higher than that in the control group(P < 0.01).After intervention, the stroke output, left ventricular ejection fraction and cardiac output significantly increased, the 6-minute walking distance significantly increased, and the N-terminal B-type natriuretic peptide significantly decreased in two groups compared with that before intervention(P < 0.05).After intervention, the improvement of cardiac function indexes in the observation group was better than that in the control group(P < 0.05 to P < 0.01).After intervention, the life quality scores in two groups were significantly improved compared with that before intervention, and the improvement of the life quality score in the observation group was higher than that in the control group(P < 0.05 to P < 0.01).

Conclusions The nursing intervention mode of combination of knowledge, faith and action theory with Rosenthal effect can effectively improve the self-management ability, health behavior and cardiac function indicators of patients with heart failure, and also improve the quality of life, which is worthy of clinical application.
