目的 :了解冠状动脉支架术后胸部不适与再狭窄关系。方法 :选择接受冠状动脉支架术并在 6个月内进行了冠状动脉造影检查的 186例患者 ,对术后胸部不适和无胸部不适患者进行冠心病易患因素和术后再狭窄比较。结果 :胸部不适和无胸部不适者术后支架内再狭窄的百分率分别为 2 1.4 %和 15 .2 % ,两组的再狭窄率差异无显著性意义。结论 :冠状动脉支架术后的胸部不适除与再狭窄有关外 ,可能与血管内皮功能紊乱及血管的反应性有关。
Objective: To understand the relationship between chest discomfort and restenosis after coronary stenting. METHODS: A total of 186 patients undergoing coronary stenting and undergoing coronary angiography within 6 months were enrolled. Patients with postoperative chest discomfort and no chest discomfort were compared for risk factors for coronary artery disease and postoperative restenosis. Results: The percentage of in-stent restenosis was 21.4% and 15.2% in patients with chest discomfort and without chest discomfort, respectively. There was no significant difference in restenosis between the two groups. Conclusion: Chest discomfort after coronary stenting is related to restenosis and vascular endothelial dysfunction and vascular reactivity.
