维吾尔族与汉族高血压伴冠心病患者冠状动脉病变的比较

目的:探讨维吾尔族与汉族高血压伴冠心病(CHD)患者的冠状动脉(冠脉)病变特点。方法:回顾性分析600例维吾尔族与汉族高血压患者行选择性冠脉造影确诊为CHD的病历资料,对其冠脉病变特点加以对比研究;冠脉病变程度用病变部位、支数、分型及病变Gensini总积分表示。结果:维吾尔族组左回旋支病变发生率高于汉族组(59.5%∶46.0%,P<0.05),单支病变发生率明显低于汉族组(28.9%∶37.9%,P<0.05),而3支病变发生率显著高于汉族组(44.3%∶25.6%,P<0.05);维吾尔族组A型病变发生率明显低于汉族组(40.9%∶62.1%,P<0.05),而C型病变发生率显著高于汉族组(32.6%∶15.2%,P<0.05);维吾尔族组Gensini总积分高于汉族组(43.1±33.0)∶(28.6±25.9),P<0.05]。结论:维吾尔族高血压伴CHD患者以3支病变率高,C型病变居多,冠脉病变程度较汉族患者严重。

Comparison of coronary artery lesions between Uygur and Han nationality hypertension patients with coronary heart disease

Objective:To study the characteristics of coronary artery lesions of coronary heart disease(CHD) in Uygur and Han nationality hypertension patients. Method:A total of 600 hypertension patients with CHD in our hospital were divided into Han group(n=309) and Uygur group(n=291).The coronary lesions were evaluated by location,quantity,type and Gensini scores. Result:The incidence of left circumflex branch lesion was significantly higher in Uygur group than that in Han group(59.5%∶46.0%,P<0.05).The incidence of single branch lesion in Uygur group was lower than that in Han(28.9%∶37.9%,P<0.05),but the incidence of 3-vessel lesions was significantly higher(44.3%∶25.6%,P<0.05).Compared with Han group,C-type lesion rate was higher(32.6%∶15.2%,P<0.05) and A-type lesion rate was lower(40.9%∶62.1%,P<0.05) in Uygur group.Gensini score of Uygur group was significantly higher than those of Han group (43.1±33.0)∶(28.6±25.9),P<0.05]. Conclusion:Uygur hypertension patients with CHD have more severe coronary artery lesions than Han patients,have high rates of 3-branch and C-type lesions.
