There are no clinical data on the efficacy of intravascular imaging-guided percutaneous coronary intervention (PCI) compared with angiography-guided PCI in patients with acute myocardial infarction (AMI) and cardiogenic shock. The current study sought to evaluate the impact of intravascular imaging-guided PCI in patients with AMI and cardiogenic shock.
Among a total of 28 732 patients from the nationwide pooled registry of KAMIR-NIH (November, 2011 to December, 2015) and KAMIR-V (January, 2016 to June, 2020), we selected a total of 1833 patients (6.4%) with AMI and cardiogenic shock who underwent PCI of the culprit vessel. The primary endpoint was major adverse cardiovascular events (MACE) at 1 year, a composite of cardiac death, myocardial infarction, repeat revascularization, and definite or probable stent thrombosis.
Among the study population, 375 patients (20.5%) underwent intravascular imaging-guided PCI and 1458 patients (79.5%) underwent angiography-guided PCI. Intravascular imaging-guided PCI was associated with a significantly lower risk of 1-year MACE than angiography-guided PCI (19.5% vs 28.2%; HR, 0.59; 95%CI, 0.45-0.77; P<.001), mainly driven by a lower risk of cardiac death (13.7% vs 24.0%; adjusted HR, 0.53; 95%CI, 0.39-0.72; P<.001). These results were consistent in propensity score matching (HR, 0.68; 95%CI, 0.46-0.99), inverse probability weighting (HR, 0.61; 95%CI, 0.45-0.83), and Bayesian analysis (Odds ratio, 0.66, 95% credible interval, 0.49-0.88).
In AMI patients with cardiogenic shock, intravascular imaging-guided PCI was associated with a lower risk of MACE at 1-year than angiography-guided PCI, mainly driven by the lower risk of cardiac death.
目前尚无血管内影像学指导的经皮冠状动脉介入治疗（PCI）与血管造影指导的 PCI 在急性心肌梗死（AMI）伴心源性休克患者中的疗效的临床数据。本研究旨在评估血管内影像学指导的 PCI 对 AMI 伴心源性休克患者的影响。
在全国性 KAMIR-NIH（2011 年 11 月至 2015 年 12 月）和 KAMIR-V（2016 年 1 月至 2020 年 6 月）登记研究中，共纳入 28732 例患者，我们从中选择了 1833 例（6.4%）接受罪犯血管 PCI 的 AMI 伴心源性休克患者。主要终点是 1 年时的主要不良心血管事件（MACE），包括心源性死亡、心肌梗死、再次血运重建和明确或可能的支架血栓形成。
在研究人群中，375 例（20.5%）患者接受血管内影像学指导的 PCI，1458 例（79.5%）患者接受血管造影指导的 PCI。与血管造影指导的 PCI 相比，血管内影像学指导的 PCI 1 年 MACE 风险显著降低（19.5% vs. 28.2%；HR，0.59；95%CI，0.45-0.77；P<.001），主要归因于心源性死亡风险降低（13.7% vs. 24.0%；调整后的 HR，0.53；95%CI，0.39-0.72；P<.001）。在倾向评分匹配（HR，0.68；95%CI，0.46-0.99）、逆概率加权（HR，0.61；95%CI，0.45-0.83）和贝叶斯分析（OR，0.66，95%可信区间，0.49-0.88）中也观察到了一致的结果。
在 AMI 伴心源性休克患者中，与血管造影指导的 PCI 相比，血管内影像学指导的 PCI 1 年时的 MACE 风险较低，主要归因于心源性死亡风险降低。
