Abstract Objective To explore the indexes of echocardiography and the incidence of myocardial infarction in elderly patients of different ages. Methods A total of 120 elderly patients with myocardial infarction who were treated in Tieling Central Hospital from September 2018 to October 2019 were selected as the research objects. They were divided into group A,group B and group C according to different ages.Group A(35 cases)aged between 60 and 70 years old,Group B (42 cases) aged between >70 and 80 years old, and Group C (43 cases) aged over 80 years old were selected. The distribution of myocardial infarction site and the distribution of ultrasonic examination indexes were compared among the three groups. Results There was no significant difference in the incidence of anterior wall, inferior wall, posterior inferior wall and anterior wall plus inferior wall among the three groups (P>0.05); the incidence of anterior and inferior myocardial infarction in group C was higher than that of posterior inferior wall and anterior wall plus inferior wall, and the difference was statistically significant (P<0.05). There was no significant difference in the incidence of centrifuge infarction among the three groups in the left ventricular diameter ≥50 mm, left atrial diameter ≥39 mm, left ventricular diameter <50 mm and left atrial diameter <39 mm (P>0.05); the incidence of myocardial infarction in group C patients with left ventricular diameter ≥50 mm and left atrial diameter ≥39 mm was higher than that in group C patients with left ventricular diameter <50 mm and left atrial diameter <39 mm, and the difference was statistically significant (P<0.05). Conclusion The diagnostic effect of echocardiography on myocardial infarction in the elderly with the age of patients, the higher the diagnostic value, the better the diagnostic effect for patients over 80 years old, which has clinical significance.
