摘要
目的探讨动态心电图(AECG)在心力衰竭患者预后中的价值。方法本研究回顾性分析了心功能不全患者78例,每例患者都有完整的临床资料和AECG资料并进行了随访。采用多元Logistic回归模型建立回归方程进行危险因素的筛选。结果在132例患者中,死亡21人。在多元Logistic回归模型中,心力衰竭的危险因素包括年龄(RR:1.02;95%CI:1.01-1.03)、低射血分数(RR:0.963;95%CI:0.948-0.982)、心率过快(RR:1.05;95%CI:1.04-1.07)、心率范围较小(RR:0.973;95%CI:0.961-0.984)、阵发性房颤(RR:1.21;95%CI:1.15-1.28)和非持续性室速(RR:1.31;95%CI:1.22-1.37)。结论AECG所监测的心率范围、阵发性房颤以及非持续性室速是心力衰竭患者死亡的危险因素。因此,AECG在心力衰竭患者的预后中有参考价值。
Objective To explore the value of ambulatory electrocardiography(AECG) in predicting the mortality of heart failure. Methods We retrospectively analyzed 78 heart failure patients who had integrated clinical and AECG data and followed-up for 52 ± 10 months. SPSS software version 13.0 (SPSS, Inc) was used for statistical analysis. Multivariate regression model was used to determine the risk factors of mortality of heart failure. Results During the follow-up period, 21 patients died. In multivariate regression model, the risk factors of mortality included age ( RR: 1.02 ; 95 % CI : 1.01 - 1.03 ), low EF ( RR: 0. 963 ; 95 % CI: 0. 948 - 0. 982 ), mean heart rate ( RR: 1.05 ; 95 % CI : 1.04 - 1.07 ), heart rate range ( RR: 0. 973 ;95% CI:0.961 - 0. 984), paroxysmal atrium fibrillation ( RR: 1.21 ;95% CI: 1.15 - 1.28) and NS- VT ( RR:1. 31 ;95% CI:1. 22 - 1.37). Conclusion Ambulatory electrocardiography provided useful prognostic information for patients with heart failure.
