Abstract

Objective To compare the dynamic electrocardiogram (DCG) and coronary CT angiography (CTA) in patients with silent myocardial ischemia (SMI), so as to investigate the clinical value of DCG and provide reference for better treatment. Methods A total of 126 patients with coronary heart disease admitted to our hospital from June 2017 to May 2018 were selected and divided into DCG group (n=63) and ECG group (n=60). The general data and the CTA results of patients were collected. Then the sensitivity, specificity and accuracy of DCG and ECG in the diagnosis of SMI were analyzed. Results The true-positive value was higher than the false-negative value in both DCG group and ECG group (P<0.05). The sensitivity, specificity and accuracy of DCG in the diagnosis of SMI were higher than those of the ECG (P<0.05). Conclusion The application of DCG can accurately detect the signs of SMI patients, which is extremely important for the prognosis assessment.
