窦性心率震荡结合室性早搏在AMI患者远期预后中的价值

目的探讨AMI患者行PCI术后,窦性心率震荡与室性早搏在其远期预后中的价值。方法67例在住院期间发生室性心律失常的AMI患者,按随访结果分死亡组和生存组。比较室早宽度、切迹数、窦性心率震荡TO、TS;并作多变量Logistic回归分析。结果生存组与死亡组的室早宽度、切迹数、TS比较有显著差异性(P<0.01);TO无显著差异(P>0.05);室早切迹数和TS与远期死亡有相关性(OR=4.641[1.376,15.653],P<0.05;OR=0.111[0.022,0.552],P<0.01)。结论HRT参数TS值与室早切迹数在急性心肌梗死患者的远期预后中有重要价值。

The Value of Heart Rate Turbulence and Premature Ventricular Contractions in Long-term Prognosis of AMI Patients

Objective To investigate the value of heart rate turbulence and premature ventricular contractions in long-term prognosis of AMI patients after PCI. Methods 67 AMI patients who had ventricular arrhythmias during their hospitalization were divided into death group and survival group by the follow-up results. Premature ventricular width and notches,TO,TS were compared. A stepwise Logistic regression analysis was used to explore prognosis and various risk factors. Results There were significant differences in premature ventricular width,notches and TS (P <0.01) between survival group and death group. And there was no significant difference in TO (P >0.05). Logistic regression analysis showed that premature ventricular notchs and TS were correlated with long-term decease (OR=4.641[1.376,15.653],P <0.05; OR=0.111 [0.022,0.552],P <0.01). Conclusion The premature ventricular notchs and TS have significant value in the long-term prognosis of patients with AMI.
