Objective To observe the comprehensive value of ECG diagnosis in patients with atypical myocardial infarction. Methods Thirty patients with atypical myocardial infarction clinically diagnosed in our hospital from March 2019 to March 2022 were selected and 30 patients with atypical myocardial infarction clinically diagnosed in the same period were selected for study. The two groups of patients were named as observation group and control group, respectively, and the differences of the first symptom and myocardial enzyme profile detection indexes between the two groups were compared. The patients underwent coronary angiography, which was used as the basis for diagnosis rate analysis to compare the diagnostic coincidence rate between the two groups. Results The examination showed that the two groups of patients in painless, atypical pain, typical chest and back + upper abdominal pain, these first symptoms, the difference was statistically significant (P＜0.05). The results showed that the indexes of cTnI, CK and CK-MB of myocardial enzyme profile in observation group were lower than those in control group, and the difference was statistically significant (P＜0.05). The coincidence rate of disease diagnosis in the two groups was calculated and compared based on the results of coronary angiography. The coincidence rate of patients in the observation group was 93.33％ (28/30), with no statistical significance (P＞0.05). Conclusion ECG is effective in the diagnosis of myocardial infarction, but it still has some limitations in the diagnosis of atypical myocardial infarction. It is suggested to combine ECG with myocardial enzyme assay for comprehensive examination of patients, so as to improve the diagnostic accuracy of the disease and provide more reliable basis for the scientific treatment of the disease.
