老年冠心病合并2型糖尿病患者冠状动脉造影结果分析

目的探讨合并2型糖尿病的老年冠心病患者冠状动脉造影的特点。方法 50例老年冠心病合并2型糖尿病患者（糖尿病组）与50例老年冠心病未合并2型糖尿病患者（对照组）,均行冠状动脉造影检查,并进行比较。结果糖尿病组冠状动脉造影主要表现为多支病变和多支多节段病变,对照组主要表现为单支病变和2支单节段病变;糖尿病组单支病变、多支病变、弥漫性狭窄病变、重度及闭塞病变发生率分别为14%,58%,78%和88%;对照组分别为44%,26%,20%和40%,2组比较差异均有统计学意义（P〈0.05）。结论老年冠心病合并2型糖尿病者冠状动脉的狭窄程度较未合并2型糖尿病者重。

Coronary angiography in coronary heart disease complicated with type 2 diabetes mellitus in the elderly patients

Objective To study the coronary angiographic features of coronary heart disease complicated with type 2 diabetes mellitus in the elderly patients. Methods Fifty elderly patients with coronary artery disease complicated with type 2 diabetes mellitus （DM group） and another fifty elderly patients with coronary heart disease not complicated with diabetes mellitus（control group） received coronary artery angiography and were compared. Results DM group was mainly demonstrated with multivessel disease or multiple stenosis, and control group was mainly demonstrated with single or two vessels disease. The incidences were 78% and 20% of extensive coronary artery disease, 88%and 40% of multiple stenosis or vascular occlusion, 58% and 26% of triple vessel coronary artery disease, and 14% and 44% of single coronary artery pathological changes in DM group and control group respectively, which showed significant differences between two groups（P〈0.05）. Conclusion Stenosis is more serious in the elderly patients with coronary heart disease complicated with type 2 diabetes mellitus than in those without type 2 diabetes mellitus.
