目的 :探讨冠状血管病变特征对支架术后再狭窄的影响。方法 :冠状动脉造影 (CAG)随访支架术后患者共 110例 ,定量 (QCA)分析术前、术后即刻和随访时靶血管造影结果 ;比较支架术前靶血管及患者临床资料 ,应用单因素和多因素回归法分析术前靶血管解剖学和临床危险因素与再狭窄的相关性。结果 :再狭窄组中术前甘油三酯有增高趋势 ,但与无再狭窄组比较差异无显著性意义 (P >0 .0 5 )。单因素分析表明 ,再狭窄组血管术前狭窄程度、靶血管最小管腔直径和病变分型与无再狭窄组比较差异显著 (P <0 .0 5 ) ;多因素逐步回归分析表明 ,术前靶血管最小管腔直径和病变分型是再狭窄形成的独立危险因素 ,其OR值分别为 0 .12 0和 2 .6 4 2。结论 :冠状血管病变特征对支架术后再狭窄具重要预测价值。
Objective: To investigate the effect of coronary angiographic features on the restenosis after stenting. Methods: Totally 110 patients underwent coronary angiography (CAG) were followed up. Quantitative QCA was used to analyze the results of target angiography before surgery, immediate follow-up and follow-up. Compared with the clinical data of target vessel and its patients, single factor And multi-factor regression analysis of preoperative target vascular anatomy and clinical risk factors and restenosis correlation. Results: Preoperative triglycerides tended to increase in the restenosis group, but there was no significant difference between the two groups (P> 0.05). Univariate analysis showed that the degree of preoperative stenosis, the minimum lumen diameter of the target vessel and the type of the lesion in the restenosis group were significantly different from those in the non-restenosis group (P <0.05). The multivariate stepwise regression analysis showed that preoperative The minimum lumen diameter and lesion type of target vessel were independent risk factors for restenosis with OR values of 0.12 and 2.642, respectively. Conclusion: The characteristics of coronary artery disease have important predictive value for the restenosis after stenting.
