目的探讨河北地区人群冠心病血管狭窄发病风险与常见危险因素的关系。方法收集医院经冠状动脉造影检查按相应标准确证为冠心病的患者250例,采用后退法Logistic回归分析冠心病血管狭窄危险因素与冠状动脉病变程度的关系。结果单因素分析显示年龄、高血压史、吸烟史在冠脉病变程度之间存在差异,性别、糖尿病史、血脂异常在病变程度方面无明显差异（P〉0.05）,多因素Logistic回归分析显示年龄、吸烟和糖尿病史是冠心病血管狭窄的主要危险因素。结论在河北人群中,冠心病血管狭窄主要与年龄、吸烟和糖尿病史有关。

Objective To investigate the correlation between cardiovascular risk factors and coronary artery stenosis in Hebei province.Methods The 250 patients who underwent coronary angiography and diagnosed as coronary artery disease（CAD） were collected from different hospitals in Hebei province.Backward Logistic analysis was used to study the severity of coronary artery stenosis and cardiovascular risk factors.Results Single factor analysis showed that the severity of coronary artery stenosis were significantly different according to age,hypertension,smoking,while sex,diabetes mellitus,and abnormal blood fats level had no difference（ P0.05）.Logistic regression analysis indicated that age,smoking and diabetes mellitus were the major risk factors for coronary artery stenosis.Conclusions Age,smoking and diabetes mellitus are closely associated with the severity of coronary artery stenosis in Hebei province.
