12294例不同年龄患者冠状动脉造影的特征及危险因素研究

目的观察不同年龄患者冠状动脉造影特征,分析其危险因素及病变特点。方法选择拟诊冠心病行冠状动脉造影的患者12294例,根据年龄将<60岁患者作为A组(6520例),≥60岁患者作为B组(5774例)。应用冠状动脉造影观察冠状动脉病变特点。结果A组男性多见,多具有吸烟习惯和冠心痛家族史,B组多合并高血压、糖尿病和高脂血症。A组单支病变发生率高,而B组多支病变发生率高。结论不同年龄的患者冠状动脉病变特征和危险因素不同,提示不同年龄患者预防冠心病各有侧重。

The risk factors and coronary angiographic characteristics in different age groups of patients

Objective To observe characteristics of coronary angiography in different age groups of patients and analyze the risk factors and the characteristics of lesions.Methods 12 294 patients with suspected coronary heart disease(CHD) and undergoing coronary angiography were enrolled. The patients were divided into group A(6 520 cases<60 years old) and group B(5 774 ca ses≥60 years old).The clinical and angiography details were recorded and retrospectively analyzed. Results Males were more common in group A.Most patients in group A had smoking habit and family history of CHD,while most patients in group B had medical history of hypertension, diabetes and hyperlipidemia.Single vessel disease was more common in group A,compared with more multiple vessel disease in group B.Conclusion Different age groups of patients have different characteristics of lesions and risk factors,indicating that different emphases showld be put on prevention of CHD for patients of different ages.
