摘要(Abstract)：

目的观察冠状动脉慢性完全闭塞病变(CTO)患者经皮冠状动脉介入治疗(PCI)术后左心室功能恢复情况与碎裂QRS波的关系。方法回顾性分析2010年1月至2014年10月成功行PCI的260例单支主要冠状动脉CTO患者,按照入院时12导联体表心电图QRS波形态分为碎裂QRS波组(f QRS组,76例)和无碎裂QRS波组(nf QRS组,184例),应用实时三维超声心电图(RT-3DE)评价左心室局部室壁运动情况,随访两组患者PCI术后6个月左心室局部室壁运动和心功能改善情况。结果两组患者PCI术后左心室射血分数(LVEF)、室壁运动计分(WMSI)、NYHA心功能分级均有所改善,但与术前相比,nf QRS波组患者术后LVEF[(42.1±3.51)%比(53.26±4.47)%,P=0.03]增加、WMSI[(1.61±0.34)比(1.25±0.27),P=0.04]减少、NYHA心功能分级亦有显著改善(P=0.04),差异均有统计学意义;而f QRS组术前、术后差异无统计学意义(P>0.05)。结论 PCI术能够改善CTO患者的心脏功能,nf QRS波患者术后心功能改善显著,分析体表心电图f QRS波可预测术后左心室局部室壁运动的恢复。
