心脏彩超对不同年龄老年急性心肌梗死患者冠脉病变程度的评估价值

Value of color Doppler echocardiography in evaluating the severity of coronary artery disease in elderly patients with myocardial infarction of different ages

目的探讨心脏彩超对不同年龄老年急性心肌梗死患者冠脉病变程度的评估价值。方法选择我院2017年1月至2020年6月收诊的120例老年急性心肌梗死患者为研究对象,根据年龄将其分为A组(60~69岁,54例)、B组(70~79岁,37例)和C组(≥80岁,29例)。对患者实施心脏彩超检查,比较三组的TIMI血流分级及心脏彩超检查结果。结果三组的冠脉管腔狭窄程度>75%占比、冠脉三支病变占比从高至低依次均为C组、B组、A组,组间比较,差异具有统计学意义(P<0.05)。Spearman相关性分析结果显示,冠脉管腔狭窄程度、冠脉病变支数与老年急性心肌梗死患者年龄呈正相关(P<0.05)。结论心脏彩超可对老年急性心肌梗死患者的冠脉病变情况进行准确判断。随着年龄的增长,患者冠脉管腔狭窄程度逐渐加重,其冠脉病变支数逐渐增多。

Objective To investigate the value of color Doppler echocardiography in evaluating the severity of coronary artery disease in elderly patients with myocardial infarction of different ages.Methods A total of 120 elderly patients with acute myocardial infarction admitted in our hospital from January 2017 to June 2020 were selected as the study objects and divided into group A(60~69 years old,54 cases),group B(70~79 years old,37 cases)and group C(≥80 years old,29 cases)according to age.The patients were examined by color Doppler echocardiography,and TIMI blood grade and color Doppler echocardiography results were compared among the three groups.Results The proportion of coronary lumen stenosis>75%and the proportion of three-vessel lesions in the three groups from high to low were group C,group B and group A,and the differences among the three groups were statistically significant(P<0.05).Spearman correlation analysis showed that the degree of coronary lumen stenosis and the number of coronary artery lesions were positively correlated with the age of elderly patients with acute myocardial infarction(P<0.05).Conclusion Color Doppler echocardiography can accurately judge the coronary artery disease in the elderly patients with acute myocardial infarction.With the increase of age,the degree of coronary lumen stenosis gradually worsened,and the number of coronary artery lesions gradually increased.
