目的:探讨前降支单支病变且接受经皮冠状动脉介入(PCI)治疗的冠心病患者侧支循环的形成情况,并对其侧支循环与心功能之间的关系进行分析。方法入选自2010年1月~2012年12月在我院行冠状动脉造影提示前降支单支病变且行PCI的冠心病患者625例进行回顾性分析,采用Rentrop法评价各组侧支循环的开放情况,并分为存在侧支循环组(A组,包括Rentrop分级1级、2级、3级,n=280)与无侧支循环组(B组,包括Rentrop分级0级,n=345)。A组根据侧支循环来源分为对侧侧支循环(A1组,n=200)、同侧+对侧侧支循环(A2组,n=44)、同侧侧支循环(A3组,n=36),分别比较A组、B组两组;A1组、A2组、A3组3组心功能恢复的差异。结果总侧支循环对心功能恢复的影响:相较于无侧支循环者,存在侧支循环组射血分数升高、脑钠肽前体降低、红细胞体积分布宽度降低的程度较大(P<0.05),左室舒张末容积增大的程度较小(P<0.05);对侧侧支循环、同侧侧支循环、对侧+同侧侧支循环3种情况下心功能恢复的关系:3种情况下心功能均有改善,对侧+同侧侧支循环对心功能改善最佳,对侧侧支循环次之,同侧侧支循环最差。结论前降支病变接受PCI治疗冠心病患者存在侧支循环者对心功能的恢复更好;对侧+同侧侧支循环较同侧侧支循环对心功能改善程度大,对侧侧支循环次之。
目的:探討前降支單支病變且接受經皮冠狀動脈介入(PCI)治療的冠心病患者側支循環的形成情況,併對其側支循環與心功能之間的關繫進行分析。方法入選自2010年1月~2012年12月在我院行冠狀動脈造影提示前降支單支病變且行PCI的冠心病患者625例進行迴顧性分析,採用Rentrop法評價各組側支循環的開放情況,併分為存在側支循環組(A組,包括Rentrop分級1級、2級、3級,n=280)與無側支循環組(B組,包括Rentrop分級0級,n=345)。A組根據側支循環來源分為對側側支循環(A1組,n=200)、同側+對側側支循環(A2組,n=44)、同側側支循環(A3組,n=36),分彆比較A組、B組兩組;A1組、A2組、A3組3組心功能恢複的差異。結果總側支循環對心功能恢複的影響:相較于無側支循環者,存在側支循環組射血分數升高、腦鈉肽前體降低、紅細胞體積分佈寬度降低的程度較大(P<0.05),左室舒張末容積增大的程度較小(P<0.05);對側側支循環、同側側支循環、對側+同側側支循環3種情況下心功能恢複的關繫:3種情況下心功能均有改善,對側+同側側支循環對心功能改善最佳,對側側支循環次之,同側側支循環最差。結論前降支病變接受PCI治療冠心病患者存在側支循環者對心功能的恢複更好;對側+同側側支循環較同側側支循環對心功能改善程度大,對側側支循環次之。

Objective To explore the relationship between coronary collateral circulation following percutaneous coronary intervention (PCI) for a single left anterior descending artery and the recovery of cardiac function. Methods A total of 625 patients with coronary heart disease were retrospectively analyzed, who received selective coronary angiography demonstrating lesions involving a single left anterior descending artery and underwent stent placement between January, 2010 and December, 2012. According to Rentrop's classification, the patients were divided into group A (n=280) with Rentrop grades 1-3 and group B (n=325) with Rentrop grade 0. Group A were further divided into 3 subgroups according to the source of collateral circulation, namely group A1 (n=200) with contralateral collateral circulation, group A2 (n=44) with contralateral+ipsilateral collateral circulation, and group A3 (n=36) with ipsilateral collateral circulation. The outcomes of cardiac function recovery were compared between groups A and B and between the 3 subgroups in group A. Results Compared with patients without collateral circulation, patients with collateral coronary circulation showed greater left ventricular ejection fraction increment and reduction in brain natriuretic peptide and red cell volume distribution width with also lower expansion left ventricular end-diastolic volume. Among the 3 subgroups in group A, cardiac function improvement was the most obvious in patients with contralateral+ipsilateral collateral circulation (group A2) followed by those in group A3, and was the worst in group A1. Conclusion The presence of collateral coronary circulation promotes cardiac function recovery in patients receiving PCI for lesions involving a single left anterior descending artery. Patients with contralateral+ipsilateral collateral circulation have the best cardiac function improvement followed by those with contralateral collateral circulation.
