Application of color Doppler ultrasound cardiogram examination in diagnosis of acute myocardial infarction

Objective To study the application of color Doppler ultrasound cardiogram examination in the diagnosis of acute myocardial infarction (AMI). Methods From March 2017 to March 2019, 92 suspected AMI patients were enrolled in a hospital. All the patients were examined by color Doppler echocardiography, color Doppler ultrasound cardiogram, and coronary angiography. The sensitivity, specificity, accuracy and coincidence rate of color Doppler echocardiography and color Doppler ultrasound cardiogram were evaluated by using the results of coronary angiography as the "gold standard". Results Among the 92 suspected AMI patients, 71 cases were confirmed by coronary angiography, and 21 cases were not. By using coronary angiography as the "gold standard", the sensitivity, specificity, and accuracy of color Doppler echocardiography in the diagnosis of AMI were 84.51%, 71.43% and 81.52%, respectively, and the area (AUC) under ROC curve was 0.803. The sensitivity, specificity, and accuracy of color Doppler ultrasound cardiogram in the diagnosis of AMI were 95.77%, 85.71%, and 93.48%, respectively, and the area (AUC) under ROC curve was 0.907. The sensitivity, accuracy, and AUC of color Doppler ultrasound cardiogram were higher than those of the color Doppler echocardiography, and there were significant differences (all P<0.05). The coincidence rate of lesion focus of color Doppler ultrasound cardiogram was 92.96%, which was significantly higher than that of color Doppler echocardiography (77.46%, χ2=6.762, P=0.009). Conclusion Color Doppler ultrasound cardiogram has high sensitivity, accuracy and coincidence rate of lesion focus in the diagnosis of AMI, and has a good diagnostic value.
