冠状动脉支架术后临床症状影响因素分析

Clinical Observation after Introcoronary Stent Implantation

目的 :探讨冠状动脉内支架植入后影响临床症状的因素。方法 :对196例植入冠状动脉支架的病人随访6个月 ,比较出现心前区不适症状病人与未出现症状者间的临床特征及病变血管类型。结果 :196例病人中有42例 ( 2 1.4% )出现心前区不适症状。临床资料中 ,糖尿病、血脂异常、吸烟、高文化程度方面因素有症状组明显高于无症状组 ,两组比较有统计学意义(P <0 .0 5 )。影像学方面 ,多支病变、分叉病变、弥漫性病变、长病变及严重狭窄病变有症状组与无症状组比较有统计学意义 (P <0 .0 5 )。结论 :糖尿病、血脂异常、吸烟、高文化程度以及多支病变、分叉病变、弥漫性病变、病变长度 >15mm、狭窄程度 >99%者 ,可以增加冠心病病人冠状动脉支架术后心前区不适症状的复发。

Objective: To evaluate factors influencing clinical symptom after introcoronary stent implantation. Methods: 196 patients with introcoronary stent implantation had been followed up 6 months. We studied the clinical and vessel lesion characteristics between the patients with and without chest symptom. Results: In 196 patients, 42(21.4%) patients had represented chest symptom. Symptomatic were more than asymptomatic in patients who had diabetes mellitus, abnormal lipid, smoking and high education .(P <0.05). The factors of multivessle lesions, bifurcation lesions, diffuse lesions, long lesions and severe stenosis lesions were dangerous to induce chest symptom (P <0.05). Conclusion:The factors such as diabetes mellitus, abnormal lipid, smoking, high education and multivessle lesions, bifurcation lesions, diffuse lesions, long lesions, severe stenosis lesions could induce the chest symptom represented after introcoronary stent implantation.
