TCT 2014:经桡动脉路径行PCI可减少患者并发症(RIVAL研究)

2014-09-23 傅向华 毕希乐 医学论坛网

TCT2014公布的一项研究表明,在NSTEMI患者中经桡动脉路径行PCI优于股动脉路径,可以减少出血、穿刺并发症和死亡率。 RIVAL研究表明,经桡动脉路径不能减少非ST段抬高急性冠脉综合征(NSTEACS)患者PCI术后的死亡率。 Iqbal等报道在这项研究中只有62%的患者心肌标志物阳性,在这些高危险NSTEACS患者中,经桡动脉路径是否能对预后获益仍需进一步研究。Iqbal

TCT2014公布的一项研究表明,在NSTEMI患者中经桡动脉路径PCI优于股动脉路径,可以减少出血、穿刺并发症和死亡率。

RIVAL研究表明,经桡动脉路径不能减少非ST段抬高急性冠脉综合征(NSTEACS)患者PCI术后的死亡率。

Iqbal等报道在这项研究中只有62%的患者心肌标志物阳性,在这些高危险NSTEACS患者中,经桡动脉路径是否能对预后获益仍需进一步研究。Iqbal研究目的是评估NSTEACS患者行PCI治疗后,桡动脉路径是否能够预示更好的临床预后。

研究者们纳入了英国伦敦共八个心脏中心从2005到2011年共10095例连续NSTEACS行PCI患者,这些患者中7820人经股动脉路径行PCI,2275人经桡动脉路径。

结果显示,桡动脉路径可以显著减少整体出血(P=0.002),减少大出血(P =0.009),减少穿刺部位出血(P =0.015),减少穿刺相关并发症(P =0.034),同时经桡动脉路径可以减少30天死亡率(P =0.021)、6个月死亡率(P =0.003)和1年死亡率(P =0.017)。经桡动脉路径可以减少PCI术后患者死亡率,但是桡动脉技术有一个学习曲线,在早期2005到2007年,经桡动脉路径并未减少死亡率,在后期2008到2011年可以明显降各时期的低死亡率。
