摘要(Abstract)：
目的评价急性心肌梗死后行急诊经皮冠状动脉介入治疗(PCI)的患者中心房颤动(房颤)/心房扑动(房扑)的发生率及其对患者预后的影响。方法本研究入选的患者为急性ST段抬高型心肌梗死,症状发作在24h内(大多数为12h内),并行急诊PCI,共计668例。将其分为房颤/房扑组(入院时或住院期间心电图检查存在房颤/房扑者)和无房颤/房扑组,除心电图外同时收集患者住院资料,包括年龄、性别、心肌梗死史、脑血管病史、高血压史、糖尿病史、冠心病家族史、急诊冠状动脉造影结果及急诊PCI术后TIMI血流分级、心功能killip分级等。结果入选的668例患者中,有房颤/房扑心电图记录者67例(约占10%),与无房颤/房扑组比较分析发现,存在房颤/房扑的患者具有以下几个临床特点:高龄;多数有既往心肌梗死或脑血管病史及糖尿病、高血压病史;冠状动脉造影显示多为多支血管病变;PCI术后梗死相关血管的TIMI血流分级低。年龄、心功能Killip分级为Ⅳ级、多支血管病变等是房颤/房扑发生的独立预示因子。房颤/房扑组住院死亡率明显高于无房颤/房扑组(9.0%vs3.1%,P<0.05),房颤/房扑组心源性休克、充血性心力衰竭、室性心律失常(特别是恶性室性心律失常)的发生率均明显高于无房颤/房扑组(P<0.05)。多因素Cox回归分析显示,房颤/房扑是住院死亡率的独立预示因子(RR值1.36,95%CI1.01～2.08)。结论房颤/房扑是急性心肌梗死急诊PCI患者群中常见的合并症与并发症,房颤/房扑的存在与住院死亡率密切相关,并受到包括年龄、性别、心功能状态(Killip分级)、血管病变支数、PCI术后TIMI血流分级等多种因素的影响,或许这些因素与房颤/房扑的发生之间存在相互影响,并将直接影响房颤/房扑患者的临床预后。
