The impact of systematic management on the cardiac function and readmission rate in patients with chronic heart failure

Abstract

Objective To explore the impact of systematic management on the cardiac function and readmission rate in patients with chronic heart failure(CHF).Methods One hundred and sixty CHF patients in Beijing Shunyi Hospital Affiliated to China Medical University from Jul.2008 to Jul.2010 were selected as our subjects and random divided into intervention (79 cases) and control group(81 cases).Patients in intervention group were received systematic therapy based on heart function and clinical syndrome including therapy plan and guiding the application of angiotensin converting enzyme inhibitor and beta blockers,and in control group were received regular therapy.The cardiac function were evaluated by 6-minute walking test (6MWT) and echocardiography,and readmission rate was observed.Results (1)The result of 6MWT in the intervention group at 6 months and 12 months were (345.27 ± 123.95) m,(368.94 ± 121.62) m,significantly higher than that of 6MWT in the control group ((282.53 ± 94.63) m,(260.07 ± 86.13) m; F between groups =38.01,P ＜0.01 ;F inner group =19.26,P ＜ 0.01 ; F across group =48.36,P ＜ 0.01).(2) Left ventricular ejection fraction in the intervention group at 6 months and 12 months were (43.48 ± 8.42) ％,(41.21 ± 6.23) ％,significantly higher than that in the control group ((37.70 ±7.13)％,(37.15 ±6.83)％ ;P ＜0.001).(3)The readmission rate in the intervention group showed a decreased trend but did not reach statistically significant difference at 6 months,while the readmission times in the intervention group at 12 months was 26,significantly lower than that in the control group (36,P =0.024).Conclusion The systematic management might improve the heart function and reduce readmission rates in patients with CHF.
