Objective:To monitor the effects of intervention and management on the quality of life and the incidence of cardiovascular events in patients with chronic heart failure in the community setting.Methods:Based on questionnaire data, 200 patients with chronic heart failure in the community were randomly divided into an observation group and a control group, with 100 cases in each group.The control group was followed up for routine health information collection at home, while the observation group received standardized community intervention for patients with chronic heart failure.The awareness rate of heart failure, rate of patients receiving drug treatment, rate of standardized drug utilization, cardiac function, satisfaction with quality of life and incidence of cardiovascular events were compared between the two groups.Results:Scientific intervention for community-dwelling patients with chronic heart failure was able to significantly improve standardized drug usage and quality of life( P<0.05).Compared with the control group, patients in the observation group showed a significantly lower probability of cardiovascular events and more favorable results measured with parameters such as blood pressure, blood glucose and heart rate after intervention.Especially noteworthy was that the effective control rate of blood pressure in the observation group reached 72.4%, which was much higher than 45.9% in the control group( χ2=14.543, P<0.05), the effective control rate of blood glucose in the observation group reached 69.4%, which was much higher than 32.7% in the control group( χ2=12.588, P<0.05), and the effective control rate of heart rate in the observation group(80.6%)was much higher than in the control group(53.1%)( χ2=13.137, P<0.05).The observation group also had better results than the control group in quitting smoking, eating a low-salt, low-fat diet, and regularly measuring blood pressure, blood glucose and body fat percentage.The MNLF score in the control group(31.21±3.01)was higher than that in the observation group(22.66±2.87), and the difference was statistically significant( t=7.26, P<0.05).The LiHFe score in the control group(39.85±6.09)was lower than that in the observation group(71.36±4.32), and the difference was statistically significant( t=18.44, P<0.05).The observation group had lower readmission frequency(46.9% vs.29.6%)and incidence of cardiovascular events(56.1% vs.31.6%)than the control group and the difference was statistically significant( χ2=12.64, 15.01, both P<0.05). Conclusions:The establishment of community intervention and management for patients with chronic heart failure can significantly improve the awareness rate of heart failure, rate of drug treatment, rate of standardized drug usage, self-management ability and quality of life, and reduce the incidence of cardiovascular events.The practice should be promoted in communities.
