心脏彩超对高血压左室肥厚伴左心衰竭的临床研究

Clinical Study on Hypertensive Left Ventricular Hypertrophy with Left Heart Failure by Color Doppler Echocardiography

目的:研究分析心脏彩超对高血压左室肥厚伴左心衰竭的临床效果。方法:选取广东省肇庆市第一人民医院在2021年5月-2023年4月期间收治的118例高血压左室肥厚伴左心衰竭患者作为研究的观察组,选取同期收治的118例健康体检者作为研究的对照组,两组均采取心脏彩超检查,分析检查结果。结果:两组的左室质量(LVM)、收缩末左室内径(LVESD)、舒张末左室内径(LVEDD)、左室重量指数(LVMI)、左房内径(LAD)、左室射血分数(LVEF)、二尖瓣舒张早期最大血流及速度比值(E/Ea)和左室短轴缩短率(LVFS)水平比较,观察组的LVM、LVESD、LVEDD、LVMI、LAD指标高于对照组,其余指标则都要低于对照组(P<0.05);在不同心功能分级患者中,随着心功能等级的增加,LVEF、E/Ea和LVFS指标水平升高,其余指标则随着心功能等级的增加而下降,三组组间对比均存在差异(P<0.05)。结论:在高血压左室肥厚伴左心衰竭患者的临床诊断中,采用心脏彩超检查有着良好的应用优势,能够判断心脏病变程度,为临床疾病治疗提供依据。

Objective:To study and analyze the clinical effect of color Doppler echocardiography on hypertensive left ventricular hypertrophy with left heart failure.Methods:118 cases of hypertensive left ventricular hypertrophy with left heart failure in the First People's Hospital of Zhaoqing City,Guangdong Province from May 2021 to April 2023 were selected as the observation group,and 118 healthy people in the same period were selected as the control group.Both groups were examined by color Doppler echocar⁃diography.Analyze the inspection results.Results:The left ventricular mass(LVM),left ventricular end systolic diameter(LVESD),left ventricular end diastolic diameter(LVEDD),left ventricular mass index(LVMI),left atrial diameter(LAD),left ventricular ejection fraction(LVEF),early maximum blood flow/ve⁃locity(E/Ea),and(left ventricular fractional shortening,LVFS)levels were compared between the two groups.The LVM,LVESD,LVEDD,LVMI,and LAD indicators in the observation group were higher than those in the control group,The other indicators were lower than the control group(P<0.05);In patients with different cardiac function grades,the levels of LVEF,E/Ea,and LVFS indicators increase with the in⁃crease of cardiac function grade,while other indicators decrease with the increase of cardiac function grade.There were differences among the three groups in comparison(P<0.05).Conclusion:In the clinical diagnosis of hypertensive left ventricular hypertrophy with left heart failure,the use of cardiac ultrasound examination has good application advantages,which can determine the degree of heart disease and pro⁃vide a basis for clinical disease treatment.
