ACC 2012:口服抗炎药减少BMS支架内晚期丢失

2012-03-30 MedSci MedSci原创

  2012年3月24日 ,美国心脏病学会(ACC)2012年会报告的一项小规模试验性研究证明,稳定性冠心病患者在经皮冠状动脉介入治疗(PCI)中如用裸金属支架治疗,加用宾达利(bindarit)可显著改善6个月后的血管造影结果。宾达利是一种口服抗炎药,可选择性抑制单核细胞趋化蛋白;与安慰剂组相比,宾达利治疗可显著减少置入裸金属支架后的支架内晚期丢失。   意大利哥伦布医院Antonio Col

  2012年3月24日 ,美国心脏病学会(ACC)2012年会报告的一项小规模试验性研究证明,稳定性冠心病患者在经皮冠状动脉介入治疗(PCI)中如用裸金属支架治疗,加用宾达利(bindarit)可显著改善6个月后的血管造影结果。宾达利是一种口服抗炎药,可选择性抑制单核细胞趋化蛋白;与安慰剂组相比,宾达利治疗可显著减少置入裸金属支架后的支架内晚期丢失。

  意大利哥伦布医院Antonio Columbo等报告,血管损伤模型证明宾达利可通过减轻血管平滑肌细胞的增生和移行,减少新血管内皮的形成。此外,宾达利还可减少新内皮巨噬细胞的含量,抑制单核细胞趋化蛋白质-1(MCP-1)。

  此项临床Ⅱ期研究总共纳入148例患者,结果显示,主要观察终点支架内晚期丢失分别为:宾达利组0.74 mm,安慰剂组1.05 mm(P=0.02)。组间严重不良心血管事件发生率没有显著差异。

  Columbo指出,在该研中观察到的支架内晚期丢失处于药物洗脱支架通常见到的中间范围,但直到6个月时宾达利组支架内晚期丢失降至0.4 mm时,宾达利才真正有价值。

  美国西奈山医学中心George•Dangas认为,考虑到很多国家仍在应用裸金属支架,这种方法值得继续研究。
