摘　　要：目的探究不同年龄老年心肌梗死患者心脏超声检查指标及心肌梗死部位疾病发生率。方法选取2018年9月~2019年10月铁岭市中心医院收治的120例老年心肌梗死患者为研究对象,按年龄不同进行分组,60~70岁为A组(35例),>70~80岁为B组(42例),80岁以上为C组(43例),比较三组患者心肌梗死部位分布情况、超声检查指标分布情况。结果三组的前壁、下壁、后下壁、前壁加下壁心肌梗死发生率比较,差异无统计学意义(P>0.05);C组患者前壁、下壁心肌梗死发生率高于后下壁与前壁加下壁,差异有统计学意义(P<0.05)。三组左心室内径≥50 mm、左心房内径≥39 mm、左心室内径<50 mm、左心房内径<39 mm患者心肌梗死发生率比较,差异无统计学意义(P>0.05);C组左心室内径≥50 mm、左心房内径≥39 mm患者心肌梗死发生率高于左心室内径<50 mm、左心房内径<39 mm患者,差异有统计学意义(P<0.05)。结论心脏超声检查对老年心肌梗死的诊断效果随着患者年龄越大,其诊断价值越高,用于80岁以上患者诊断效果更佳,具有临床应用意义。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.
