Objective To explore the clinical application value of combined detection of echocardiography, dynamic electrocardiogram, and plate exercise test in the diagnosis of coronary heart disease. Methods 70 suspected coronary heart disease patients were selected and subjected to plate exercise test, dynamic electrocardiogram, echocardiography, and coronary angiography. Analyze the diagnostic performance of each method through ROC curve, and calculate sensitivity, specificity, and AUC values. Results The individual detection AUC values of the three methods were 0.796 (plate exercise test), 0.737 (dynamic electrocardiogram), and 0.773 (echocardiogram), respectively, and the combined detection AUC was 0.826. Conclusion Combined detection can significantly improve the diagnostic accuracy of coronary heart disease, with higher sensitivity and specificity than single detection. It is recommended to widely apply it in clinical practice.
