目的 比较动态心电图在糖尿病及非糖尿病人群中诊断冠心病的临床意义。方法 将 188名冠心病患者分为糖尿病组 (n =65 )及非糖尿病组 (n =12 3 ) ,根据冠状动脉造影及动态心电图结果分别计算两组动态心电图的诊断敏感性、特异性等参数 ,并用Logistic回归分析影响动态心电图结果的因素。结果 :糖尿病组动态心电图诊断冠心病的敏感性高于非糖尿病组 (P =0 0 46)。冠脉病变血管数、有无弥漫性病变及血管完全闭塞等因素与ST段阳性改变相关 (OR =2 3 6,4 91,3 90 )。结论 虽然动态心电图的敏感性、特异性有限 ,但是在糖尿病合并冠心病这样一个特殊人群 ,仍有一定的诊断价值
Objective To compare the clinical significance of ambulatory electrocardiogram in diagnosing coronary heart disease in diabetics and non-diabetics. Methods 188 patients with coronary heart disease were divided into diabetic group (n = 65) and non-diabetic group (n = 12 3). According to coronary angiography and ambulatory electrocardiogram, the diagnostic sensitivity, specificity and other parameters , And use Logistic regression analysis of the factors that affect the results of Holter. Results: The sensitivity of dynamic electrocardiogram in diagnosing coronary heart disease in diabetic group was higher than that in non-diabetic group (P = 0.046). The number of coronary vessels, diffuse lesions and complete occlusion of blood vessels were correlated with the positive changes of ST segment (OR = 2346,491,390). Conclusions Although the sensitivity and specificity of Holter monitoring are limited, there is still some diagnostic value in such a special population with diabetes complicated with coronary heart disease
