冠状动脉内支架置入后再狭窄的临床危险因素探讨

Clinic study of coronary stent restenosis

目的 :探讨临床因素对冠状动脉 (冠脉 )内支架置入后再狭窄的影响。方法 :选择成功施行冠脉支架置入并进行临床和血管造影随访的 78例冠心病患者。按造影结果分为再狭窄组 (n =4 9)和无再狭窄组 (n=2 9)。比较支架置入前临床资料 ,应用单因素和多因素回归分析法分析术前临床危险因素与再狭窄的相关性。结果 :多因素逐步回归分析认为 ,患者术前的不稳定型心绞痛 (UA)是再狭窄形成的独立危险因素 (P <0 .0 5 ,OR :3.0 93)。结论 :临床因素与预后有关 ,UA是介入治疗预后和再狭窄发生的重要影响因子。

Objective: To investigate the relation between coronary stent restenosis and clinic factors. Method: Seventy eight patients with coronary stenting were classified into restenosis group and non restenosis group by angiography after coronary stent placement 4～6 months. Relationship between restenosis and some clinical factors was studied using univariate and multivariate analysis. Result: Logistic regression analysis revealed that unstable angina was associated with restenosis after stenting. (P< 0.05 , OR: 3.093 ).Conclusion:Unstable angina is related with stent restenosis.
