目的探讨窦性心率震荡(Heart rate trubulence,HRT)对急性冠脉综合征(Acute Coronary Syndrome,ACS)患者预后影响。方法观察182例ACS患者发病后5~20 d HRT参数TO、TS值。结果随访(21±13.3)个月,死亡21例。分析显示ACS死亡与HRT分类、低左心室射血分数及高龄显著相关。差异均有统计学意义。结论 ACS的死亡与TO和TS异常增高有关。提示HRT是可以作为ACS患者判断预后的一项指标。
Objective To investigate the effect of heart rate trubulence (HRT) on the prognosis of patients with acute coronary syndrome (ACS). Methods The TO and TS values of HRT parameters in 182 patients with ACS were observed after 5 ~ 20 d. Results Follow up (21 ± 13.3) months, 21 died. Analysis showed that there was a significant association between ACS death and HRT classification, low left ventricular ejection fraction and advanced age. The differences were statistically significant. Conclusion The death of ACS is related to the abnormal increase of TO and TS. Tip HRT can be used as an indicator of prognosis in patients with ACS.
