【摘要】：目的:1.探讨高频心电图和运动平板试验在糖尿病患者中冠心病的诊断价值。2.比较高频心电图和运动平板试验在糖尿病患者中冠心病的诊断价值。3.比较高频心电图和运动平板试验在糖尿病患者中检出不同冠脉病变血管支数的阳性率。4.探讨高频心电图和运动平板试验联合检测在糖尿病患者中冠心病的诊断价值。方法:收集石河子大学医学院第一附属医院2015年12月至2016年6月疑诊冠心病的糖尿病患者138例,平均年龄54.22±8.47岁,其中男性81例,年龄38-75岁,平均年龄53.60±8.21岁,女性57例,年龄40-72岁,平均年龄55.09±8.83岁;同期行高频心电图、运动平板试验和选择性经皮冠状动脉造影检查,以冠状动脉造影结果(一支以上冠状动脉狭窄≥50%)作为诊断冠心病的“金标准”,比较高频心电图和运动平板试验在糖尿病患者中冠心病的诊断价值。皆在进一步评估无创性检查高频心电图和运动平板试验诊断糖尿病患者冠心病中的价值及应用前景。结果:1.高频心电图对糖尿病患者冠心病诊断的灵敏度是75.34%,特异度是89.23%,假阳性率是10.77%,假阴性率是24.66%,阳性预测值是88.71%,阴性预测值是76.32%,Youden指数是64.57%,正确率是81.88%。2.运动平板试验对糖尿病患者冠心病诊断的灵敏度是63.01%,特异度是78.46%,假阳性率是21.54%,假阴性率是36.99%,阳性预测值是76.67%,阴性预测值是65.38%,Youden指数是41.47%,正确率是70.29%。3.随着糖尿病患者冠脉病变支数的增加,高频心电图阳性率增加,差异有统计学意义(P0.05)。4.高频心电图和运动平板试验对冠脉双支及三支病变检出的阳性率明显高于对单支病变检出的阳性率,差异有统计学意义(P0.05)。5.高频心电图和运动平板试验进行并联试验,可明显提高糖尿病患者冠心病诊断的灵敏度,减少漏诊率,可作为糖尿病患者早期诊断冠心病的筛查指标。结论:1.高频心电图与运动平板试验相比,对糖尿病患者冠心病的诊断有较高的灵敏度、特异度和预测准确性,是糖尿病患者筛查冠心病的一种简便和安全可靠的无创性检查方法。2.高频心电图和运动平板试验对冠脉双支及三支病变的阳性检出率明显高于单支病变。3.高频心电图和运动平板进行并联试验可提高糖尿病患者冠心病诊断的准确性。
[Abstract]:Purpose 1. To investigate the diagnostic value of high frequency electrocardiogram (ECG) and treadmill exercise test in the diagnosis of coronary heart disease (CHD) in diabetic patients. To compare the diagnostic value of high frequency electrocardiogram (ECG) and treadmill exercise test in the diagnosis of coronary heart disease (CHD) in diabetic patients. Compare the positive rate of high frequency electrocardiogram (ECG) and exercise treadmill test in detecting vessel number of different coronary lesions in diabetic patients. 4. 4. To evaluate the diagnostic value of high-frequency electrocardiogram (ECG) combined with treadmill exercise test in the diagnosis of coronary heart disease (CHD) in diabetic patients. Methods: 138 diabetic patients with suspected coronary heart disease were collected from the first affiliated Hospital of Shihezi University Medical College from December 2015 to June 2016, with an average age of 54.22 卤8.47 years, including 81 males aged 38-75 years, with an average age of 53.60 卤8.21 years and 57 females. Age 40-72 years (mean 55.09 卤8.83 years), high frequency electrocardiogram (ECG), treadmill exercise test and selective percutaneous coronary angiography (PCAG) were performed at the same time. The diagnostic value of high frequency electrocardiogram (ECG) and exercise treadmill test in the diagnosis of coronary heart disease (CHD) was compared with the results of coronary angiography (鈮，
