Abstract: Objective To explore the effect of optimized nursing model on improving sleep quality and emotional state of patients with congestive heart failure.Methods Patients with con-gestive heart failure were randomly divided into control group and observation group with 76 pa-tients in each group.Patients in the control group were received conventional nursing while the pa-tients in the observation group were given optimized nursing model.Sleep quality and emotional state of two groups were evaluated by PSQI and SCL-90 before and after treatment.Results At the seventh day,the scores of sleep quality,fall sleep time,sleep time,sleep efficiency,sleep dis-orders and total score of PSQI in the observation group were all lower than that of control group, the difference was statistically significant(P <0.05).At the seventh day,scores of the indicators of SCL-90 were lower than that in the control group (P <0.05).Conclusion Optimized nurs-ing model could effectively improve the sleep quality and emotional state of patients with congestive heart failure.
