血管内超声 (IVUS) 引导的皮肤冠状动脉干预 (PCI) 在复杂和非复杂的程序中显示出类似的1年结果. 这项研究发现,两组之间主要不良心脏和脑血管事件 (MACCE) 没有显著差异.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 医疗成像医学成像
背景情况:
- 穿皮冠状动脉干预 (PCI) 是心血管疾病管理的基石.
- 复杂的PCI案件存在独特的挑战,与简单的程序相比,其结果可能会有所不同.
- 血管内超声波 (IVUS) 在优化复杂的PCI结果中的作用仍然是研究领域.
研究的目的:
- 评估IVUS引导的复杂PCI是否达到与非复杂PCI可比的临床结果.
- 评估在接受复杂与非复杂多血管PCI的患者中发生的一年重大心脏和脑血管不良事件 (MACCE) 的发生率.
- 确定IVUS指导是否可以减轻复杂的PCI案件中的潜在结果差异.
主要方法:
- 在OPTIVUS-Complex PCI研究中,有1011名患者接受了针对左前下降冠状动脉 (LAD) 的多血管PCI.
- 根据程序特征,患者被分为复杂的PCI (N=760) 和非复杂的PCI (N=251) 组.
- 复杂的PCI标准包括:3个血管接受治疗,3个植入的支架,3个治疗的病变,2个支架的分支,支架总长度>60毫米或慢性全闭目标.
主要成果:
- 复杂PCI组的1年累计MACCE发病率为10.9%,而非复杂PCI组的8.3% (P=0.24).
- 一年内任何冠状动脉再血管化的发生率为复杂PCI的7.7%,非复杂PCI的4.8% (P=0.12).
- 多变量分析显示,复杂PCI组中没有MACCE (HR,1.35;95%CI,0.83-2.18;P=0.22) 或再血管化 (HR,1.64;95%CI,0.87-3.06;P=0.11) 的显著风险过剩.
结论:
- 在LAD中IVUS引导的多血管PCI在复杂和非复杂的PCI组之间没有显示显著不同的1年MACCE或再血管化率.
- 虽然数字上更高,但与复杂的PCI相关的风险在这个队列中与非复杂的PCI相比,在统计学上并不显著.
- 这些发现表明,IVUS指导可能有助于实现复杂PCI的可比结果,尽管在复杂的情况下观察到更高事件的趋势.
