目的：明确支架影像增强显影技术（StB）在急性ST段抬高型心肌梗死患者经皮冠状动脉介入治疗中的作用。方法连续入院行PCI治疗的STEMI患者111例均接受StB检查。根据图像质量效果分为三组：优，次优，差。结果本研究中81.1%的病例图像质量优，18.9%的病例图像质量次优，无图像质量差病例。结论 StB成像简便快速，能增强支架的可视性，对支架的膨胀及贴壁情况进行评价，可以很好地应用于STEMI患者PCI中。

Objective To evaluate the effects of Stent Boost (StB) in guiding percutaneous coronary intervention (PCI) in patients with ST-elevation myocardial infarction (STEMI). Methods A total of 111 consecutive patients admitted to undergo PCI received StB. The collected images were automatically superposed and transformed to the digital film to display the stents before the images were automatically transferred into the work station for analyzing expansion and adherence of the stents. The quality of the images were divided into 3 grades: optimal visualization, suboptimal visualization, and poor visualization. Results 81.1%of the images were evaluated as of optimal visualization, 18.9%as suboptimal. No poor visualization was found. Conclusion Simple and rapid in imaging, StB may increase visibility of enhanced stents and clearly display the expansion and adherence of the stents. Thus it can be used in guiding PCI in patients with STEMI.
