探究心电图联合超声心动图在诊断心肌淀粉样变中的临床价值

Clinical Value of Electrocardiogram Combined with Echocardiography in the Diagnosis of Myocardial Amyloidosis

目的探讨心肌淀粉样变中应用心电图联合超声心动图进行诊断的价值。方法选取2015至2018年我院收治的112例高度疑似心肌淀粉样变患者,分别对其进行单一超声心电图和心电图联合超声心动图两种检查。对所有患者进行病理学检查,以患者的病理学检查结果来判断心电图和超声心动图的检测信度和效度。结果经病理学检查后,112例患者中有103例高度疑似心肌淀粉样变患者被确诊为心肌淀粉样变,9例高度疑似心肌淀粉样变患者被确诊为非心肌淀粉样变。经单一超声心电图检查后,确诊为心肌淀粉样变的患者有83例,非心肌淀粉样变的患者有29例,诊断的准确度为74.12%;经心电图联合超声心电图检查后,确诊患者有100例,剩余12例未被检查出来,心电图联合超声心电图检查的诊断准确度为89.29%。结论在心肌淀粉样变的临床诊断中,心电图联合超声心电图检查具有很好的效果,可提高诊断准确率,应在临床中广泛应用。

Objective to explore the diagnostic value of electrocardiogram combined with echocardiography in myocardial amyloidosis. Methods a total of 112 patients with highly suspected myocardial amyloidosis admitted and treated in our hospital from 2015 to 2018 were selected for the examination of single ultrasound electrocardiogram and electrocardiogram combined with echocardiography. All patients were subjected to pathological examination to determine the reliability and validity of electrocardiogram and echocardiography. Results after pathological examination, 103 patients with highly suspected myocardial amyloidosis of 112 cases were diagnosed as myocardial amyloidosis and 9 patients with highly suspected myocardial amyloidosis were diagnosed as non-myocardial amyloidosis. 83 cases were diagnosed with myocardial amyloidosis and 29 cases were diagnosed with non- myocardial amyloidosis, and the diagnostic accuracy was 74.12%. After electrocardiogram combined with ultrasonic electrocardiogram, 100 patients were diagnosed, and the remaining 12 were not examined. The diagnostic accuracy of electrocardiogram combined with ultrasonic electrocardiogram was 89.29%. Conclusion in the clinical diagnosis of myocardial amyloidosis, electrocardiogram combined with ultrasonic electrocardiogram has a good effect, which can improve the diagnostic accuracy and should be widely used in clinical practice.
