摘要
目的探讨影响植入型心律转复除颤器（IcD）术后发生电风暴（ES）患者远期预后的预测因子。方法回顾性分析2003年1月至2011年9月在南京医科大学第一附属医院心脏科植入ICD术后发生Es进行或未进行射频导管消融的47例患者的相关临床参数。结果47例患者平均年龄（51±14）岁，平均随访18个月，心脏性死亡10例。多因素Cox回归分析显示QRS时限为影响ICD术后发生Es患者生存情况的预测因子[危险比（HR）=1．042，P=0．012]，射频导管消融治疗不能改善患者的预后（HR=0．034，P=0．347）。对于QRS时限≥110ms的患者，射频导管消融治疗也不能影响患者的生存情况（HR=0．037，P=0．395）。结论QRS时限可作为ICD植人术后发生Es患者远期预后的预测因子，射频导管消融并不能改善此类患者的预后。
Objective To explore prognostic factors in patients with implantable cardioverter defibril- lators（ICD） and electrical storm（ES） attacks. Methods Retrospective analysis of the clinical parameters of patients with ICDs and ES attacks was performed from January 2003 to September 2011 in our electrophysiology center. Results Forty-seven patients with an average age of（ 51 ~ 14）years were enrolled. Ten cases of death from cardiac attacks were incurred in the follow-up within a median of 18 months. Cox regression analysis showed that QRS duration could predict survival in patients with ICDs and ES attacks（ HR= 1. 042 ,P= O. 012）. However, catheter radiofrequeney ablation could not improve the prognosis of these patients （HR = 0. 034, P=0. 347） as well as those with QRS duration≥110 ms （HR=0. 037,P=0. 395）. Conclusion QRS dura- tion can be used as a long-term predictor in patients with ICDs and ES attacks.Radiofrequency catheter ablation does not improve the prognosis of these patients.
