目的探讨择期经皮冠状动脉介入治疗(PCI)中心律失常发生的危险因素。方法纳入2000年1月~2011年12月在我院行PCI发生严重心律失常患者资料,回顾性统计分析相关危险因素。结果 12年PCI术中严重心律失常累计发生率为5.7%,2005年后发生率明显下降。严重心律失常相关危险因素包括:右冠开口或左主干病变、有心力衰竭或心肌梗死病史。结论右冠开口或左主干病变、有心力衰竭或心肌梗死病史均为PCI中严重心律失常发生的危险因素,提高临床技能及改善临床仪器设备可使得严重心律失常的发生率逐渐降低。
Objective To explore the risk factors of arrhythmia in elective percutaneous coronary intervention (PCI). Methods The data of patients with severe arrhythmia undergoing PCI in our hospital from January 2000 to December 2011 were retrospectively analyzed and relevant risk factors were retrospectively analyzed. Results The cumulative incidence of serious arrhythmia in PCI during the past 12 years was 5.7%. The incidence after 2005 was significantly lower. Risk factors associated with severe arrhythmia include: right coronary ostial or left main lesion with a history of heart failure or myocardial infarction. Conclusions The history of right coronary artery or left main coronary artery disease with history of heart failure or myocardial infarction are all risk factors of severe arrhythmia in PCI. Increasing clinical skills and improving clinical equipment can reduce the incidence of serious arrhythmia.
