目的:探讨心率振荡(HRT)对慢性心力衰竭(CHF)患者住院病死率的影响。方法:选择101例CHF住院患者,根据24h动态心电图计算患者的振荡初始(TO)和振荡斜率(TS),并记录与预后相关的指标,包括:年龄、性别、吸烟、高血压、糖尿病、血脂异常、血尿酸异常、左心室射血分数(LVEF)。以住院期间预后为终点事件,分析各项指标与患者死亡的相关性。结果:HRT、糖尿病、LVEF与CHF患者的死亡显著相关(P<0.05或P<0.01)。结论:HRT是CHF患者住院病死率的良好预测指标。
Objective: To investigate the impact of heart rate oscillation (HRT) on in-hospital mortality in patients with chronic heart failure (CHF). Methods: A total of 101 hospitalized CHF patients were enrolled. Patients’ oscillatory initial (TO) and oscillation slope (TS) were calculated according to 24h ambulatory electrocardiogram. The prognostic indexes including age, sex, smoking, hypertension, diabetes, Abnormalities, abnormal uric acid, left ventricular ejection fraction (LVEF). The prognosis as the end point of hospitalization, analysis of the correlation between the indicators and the patient’s death. Results: There was a significant correlation between HRT, diabetes, LVEF and death of CHF patients (P <0.05 or P <0.01). Conclusion: HRT is a good predictor of in-hospital mortality in CHF patients.
