Objective:This study aims to compare the diagnostic efficacy of Doppler color echocardiography and electrocardiogram in patients with acute myocardial infarction(AMI)in detail.Methods:This study selected 60 suspected AMI(Acute Myocardial Infarction)patients treated at the Yujiang District People's Hospital,Yingtan City from March 2020 to March 2022.All cases of myocardial infarction were evaluated with coronary angiography as the benchmark.The diagnostic processes were standardized.Additionally,the study statistically compared the diagnostic value of two examination measures in patients with AMI.Results:Among the 60 suspected AMI patients,a total of 41 cases were detected by coronary angiography;A total of 40 cases were detected by Doppler color echocardiography,and 33 cases were detected by electrocardiogram.Using coronary angiography as the"gold standard"for examination,the sensitivity,accuracy,and negative predictive value of Doppler color echocardiography in detecting AMI were 95.12%(39/41),95.00%[(39+18)/60],and 90.00%(18/20),which were higher than those of electrocardiography 73.17%(30/41),76.67%[(30+16)/60],and 59.26%(16/27),with statistical differences(P<0.05);The Kappa test showed excellent consistency between the results of Doppler color echocardiography and the"gold standard"examination(Kappa value=0.886,P=0.000).Conclusion:The research findings emphasize that Doppler color echocardiography optimizes the sensitivity and accuracy of diagnosis in the diagnosis of acute myocardial infarction(AMI).This conclusion provides key guidance for clinical practice,promotes the efficiency and accuracy of diagnostic procedures,and has high diagnostic value.
