摘要
目的对动态心电图及超声心动图诊断冠心病无症状性心肌缺血的价值进行评价。方法选取2018年5月至2019年5月来我院进行诊疗的45例冠心病患者作为本次试验的研究对象,分别给予动态心电图检查和超声心动图检查。以冠状动脉造影的结果为准,将两种不同检查方式与冠状动脉造影检查结果进行比较。比较两组患者的阳性检出率、阴性检出率,以及对心肌缺血的诊断价值。结果动态心电图检查结果显示阳性检出率为68.89%,显著高于超声心动图检查阳性检出率48.89%,差异显著,P <0.05;动态心电图检查诊断冠心病无症状性心肌缺血准确度、敏感度、特异度分别为73.33%、71.88%、76.92%,均显著高于超声心动图检查结果(分别为48.89%、38.71%、71.43%),差异显著,P <0.05。结论对于无症状性心肌缺血的冠心病患者采用24 h动态心电图检查方法过程简单,阳性诊出率、准确度、敏感性、特异性均较高。
Objective To evaluate the value of holter and echocardiography in the diagnosis of asymptomatic coronary heart disease with myocardial ischemia. Methods Forty-five patients with coronary heart disease who came to our hospital for diagnosis and treatment from May 2018 to May 2019 were selected as the research objects of this trial, and they were given holter and echocardiography. Based on the results of coronary angiography, compare the two different examination methods with the results of coronary angiography. The positive detection rate and negative detection rate of the two groups of patients were compared, as well as the diagnostic value of myocardial ischemia. Results The result of holter examination showed that the positive detection rate was 68.89%, which was significantly higher than the positive detection rate of 48.89% by echocardiography. The difference was significant, P <0.05;The accuracy of holter in the diagnosis of asymptomatic myocardial ischemia in coronary heart disease was the sensitivity and specificity were 73.33%, 71.88%, and 76.92%, which were significantly higher than the results of echocardiography(48.89%, 38.71%, 71.43%, respectively), and the difference was significant, P <0.05. Conclusion For patients with coronary heart disease with asymptomatic myocardial ischemia, the 24 hour dynamic electrocardiogram method is simple, and the positive diagnosis rate, accuracy, sensitivity and specificity are high.
