JAHA:冠状动脉多支病选择完全血运重建还是不完全血运重建?

2016-12-17 haofan MedSci原创

完全血运重建与降低的死亡率和主要心血管不良事件风险有关,不论不完全血运重建的定义基于解剖或评分以及与完全血运重建程度相关的这种风险等级大小。这些结果对于冠状动脉多支病变患者介入治疗意义重大。

多达一半的经皮冠状动脉介入治疗患者有冠状动脉多支病变(MVD),对于此类患者采取最佳的血运重建策略说法尚未统一。近日,心血管病领域权威杂志JAHA(IF:5.117)上发表了一篇荟萃分析文章,旨在评估经皮冠状动脉介入治疗患者完全血运重建与不完全血运重建的证据,以及其对患者预后的影响。

研究人员检索了PubMed、EMBASE、MEDLINE、Current Contents Connect、谷歌学术、Cochrane图书馆、Science Direct以及Web of Science等数据库,来评估多支冠状动脉病变患者接受经皮冠状动脉介入治疗时完全血运重建与主要不良心脏事件和死亡之间的相关性。研究者采用随机效应Meta分析评估不良预后的发生几率,采用Meta回归分析来评估连续变量和结局的关系。

研究人员确定了38个已发表的研究包含了156,240名研究对象。死亡(比值比为0.69,95%可信区间为0.61-0.78),再次血运重建(比值比为0.60,95%可信区间为0.45-0.80),心肌梗死(比值比为0.64,95%可信区间为0.50-0.81)和主要心脏不良事件(比值比为0.63,95%可信区间为0.50-0.79)的发生几率在完全血运重建的患者中显著降低。不考虑完全血运重建的定义在亚组分析中这些结果未见改变。在慢性完全闭塞病变(CTO)的亚组中进行完全血运重建研究时也得到了类似的结果(比值比为0.65,95%可信区间为0.53-0.80)。Meta回归分析发现死亡率的比值比与完全血运重建的百分比成负相关。

综上所述,不论不完全血运重建的定义基于解剖或评分以及与完全血运重建程度相关的这种风险等级大小,完全血运重建与降低的死亡率和主要心血管不良事件风险有关。这些结果对于冠状动脉多支病变患者介入治疗意义重大。
