背景:已有研究表明,与裸金属支架相比,紫杉醇洗脱支架(PES)可降低再狭窄发生率和再次血运重建的需要。然而,紫杉醇对血管功能的远期作用仍不明确。本研究旨在评价PES置入后冠状动脉对运动的血管舒缩反应。方法:通过对27例冠状动脉疾病患者行静息时和
BACKGROUND: Studies have shown that paclitaxel-eluting stents (PES) reduce the incidence of restenosis and the need for revascularization in comparison to bare-metal stents. However, the long-term effect of paclitaxel on vascular function remains unclear. The aim of this study was to evaluate the vasomotor responses of coronary arteries to PES after implantation. Methods: 27 patients with coronary artery disease during rest and rest
