彩色多普勒超声心动图在急性心肌梗死诊断中的应用效果探讨

Application of Color Doppler Echocardiography in the Diagnosis of Acute Myocardial Infarction

目的探究彩色多普勒超声心动图在急性心肌梗死诊断中的应用效果。方法将2017年2月—2018年2月期间在该院接受诊治的90例急性心肌梗死患者作为该次研究的主要对象,并将其随机分至两组,研究诊断组45例患者采用彩色多普勒超声心动图进行诊断,对照诊断组45例患者采用常规心电图进行诊断,诊断结束后,对两组患者的诊断准确率及漏诊率进行调查。结果研究诊断组中共诊断出下壁心肌梗死患者19例,诊断准确率为86.36%,右室心肌梗死患者15例,诊断准确率为83.33%,非Q波型心肌梗死患者4例,诊断准确率为80.00%;对照诊断组中共诊断出下壁心肌梗死患者14例,诊断准确率为60.87%,右室心肌梗死患者12例,诊断准确率为75.00%,非Q波型心肌梗死患者2例,诊断准确率为33.33%。研究诊断组检出率高达84.44%,仅7例患者出现漏诊,漏诊率为15.56%,而对照诊断组检出率仅为62.22%,组中有17例患者被漏诊,漏诊率高达37.78%。数据经检验差异有统计学意义(χ~2=11.05,P<0.05)。讨论采用彩色多普勒超声心动图为急性心肌梗死患者进行诊断,诊断检出率更高,效果明显,值得推广。

Objective To investigate the effect of color Doppler echocardiography in the diagnosis of acute myocardial infarction. Methods 90 patients with acute myocardial infarction who were treated in the hospital from February 2017 to February 2018 were included as subjects of this study, and were randomly assigned to two groups. Doppler echocardiography was used for diagnosis. In the control group, 45 patients were diagnosed by conventional electrocardiogram. After the diagnosis, the diagnostic accuracy and missed diagnosis rate of the two groups were investigated. Results A total of 19 patients with inferior myocardial infarction were diagnosed in the study group. The diagnostic accuracy was 86.36%, 15 patients with right ventricular myocardial infarction, the diagnostic accuracy was 83.33%, and 4 patients with non-Q-wave myocardial infarction were diagnosed accurately rate of 80.00%; 14 patients with inferior myocardial infarction were diagnosed in the control group, the diagnostic accuracy was 60.87%, 12 patients with right ventricular infarction, the diagnostic accuracy was 75.00%, and 2 patients with non-Q-wave myocardial infarction diagnostic accuracy rate was 33.33%. The detection rate of the study diagnosis group was as high as 84.44%. Only 7 patients had missed diagnosis. The missed diagnosis rate was 15.56%, while the detection rate of the control diagnosis group was only 62.22%. 17 patients in the group were missed, and the missed diagnosis rate was as high as 37.78%. The data were statistically significant (χ^2=11.05, P<0.05). Conclusion Color Doppler echocardiography is used for the diagnosis of patients with acute myocardial infarction. The diagnostic detection rate is higher and the effect is obvious, which is worthy of promotion.
