Abstract: Objective To investigate risk factors for postoperative ipsilateral cerebral infarction and all-cause mortality after coronary stent implantation in patients with asymptomatic carotid artery stenosis (ACS). Methods 110 patients with carotid stenosis of 50% or more were included in the study. The relationship including carotid intraplaque hemorrhage (IPH), ipsilateral cerebral infarction and all-cause mortality was analyzed retrospectively. Results Sixteen cases of IPH occurred in 110 ACS patients(14.5%). Six cases of IPH (37.5%) and 6 cases (6.4%) encountered ipsilateral infarction and all-cause mortality, respectively. Multivariate Cox regression analysis showed that IPH was a predictor of ipsilateral cerebral infarction (HR:18.47,95%CI: 5.14~76.08,P<0.001)and all-cause mortality and all-cause mortality (HR:4.26, 95%CI: 1.48~11.76, P=0.016). Conclusion In patients with ACS undergoing coronary stent implantation, IPH is associated with a high risk of postoperative cerebral infarction and all-cause mortality.

摘要: 目的 探讨无症状颈动脉狭窄(ACS)患者冠状动脉支架植入手术后并发脑梗塞和死亡的危险因素。方法 110例颈动脉面积狭窄达50%或以上的患者被纳入研究。回顾性分析术前颈动脉粥样硬化斑块内出血(IPH)等因素与术后同侧脑梗塞及死亡率的关系。结果 110例ACS患者中共发生16例IPH(14.5%),其中有6例IPH(37.5%)和6例(6.4%)分别发生同侧脑梗塞和全因死亡。多变量Cox回归分析显示IPH是同侧脑梗塞和全因死亡率的预测因素(HR:18.47,95%CI:5.14~76.08,P<0.001)和全因死亡率(HR:4.26,95%CI:1.48~11.76,P=0.016)。结论 在接受冠状动脉支架植入手术的ACS患者中,IPH与术后脑梗塞和全因死亡率的高风险密切相关。
