基于超声心动图评价高血压性心脏病患者左心功能、血流动力学特征

Evaluation of Left Ventricular Function and Hemodynamic Characteristics in Patients with Hypertensive Heart Disease Based on Echocardiography

目的:基于超声心动图评价高血压性心脏病患者左心功能、血流动力学特征。方法:随机选取泰州市第三人民医院2019年6月-2022年3月的高血压性心脏病患者110例作为研究组,另选取同期在本院进行超声心动图检查的健康体检者110例作为对照组,记录两组研究对象的超声心动图检测结果,根据检查结果对两组研究对象的左心房功能相关指标参数,包括左心房内径(LAD)、左心房内径指数(LADI)、左心室收缩末期内径(LVESD)、左心室舒张末期内径(LVEDD)、左心室射血分数(LVEF),以及血流动力学特征指标相关参数,包括心排血量(CO)、心排指数(CI)、每搏量(SV)、每搏指数(SVI)及不同高血压分级患者的左心功能和血流动力学特征指标相关参数进行对比分析。结果:与对照组比较,研究组LAD、LADI、LVESD、LVEDD指标参数均显著升高,LVEF指标参数显著下降,差异均有统计学意义(P<0.05)。与对照组比较,研究组CO、CI、SV、SVI指标参数均显著下降,差异均有统计学意义(P<0.05)。高血压Ⅲ级患者的LAD、LADI、LVESD、LVEDD指标参数均高于Ⅰ、Ⅱ级,LVEF指标参数低于Ⅰ、Ⅱ级(P<0.05),Ⅱ级患者的LAD、LADI、LVESD、LVEDD指标参数均高于Ⅰ级,LVEF指标参数低于Ⅰ级(P<0.05)。高血压Ⅲ级患者的CO、CI、SV、SVI参数均显著低于Ⅰ、Ⅱ级,差异均有统计学意义(P<0.05),Ⅱ级患者的CO、CI、SV、SVI参数均显著低于Ⅰ级,差异均有统计学意义(P<0.05)。结论:超声心动图能有效评价患者的左心功能和血流动力学水平,在临床中具有一定应用价值。

Objective:To evaluate the left ventricular function and hemodynamic characteristics of patients with hypertensive heart disease based on echocardiography.Method:One hundred and ten patients with hypertensive heart disease who were treated in Taizhou Third People's Hospital from June 2019 to March 2022 were randomly selected as the study group.At the same time,one hundred and ten healthy people who underwent echocardiography examination in author's hospital during the same period were selected as the control group,and the echocardiography test results of the two groups of subjects were recorded.According to the examination results,the left atrial function related index parameters of the two groups of subjects include left atrial diamete(LAD),left atrial diameter index(LADI),left ventricular end systolic diameter(LVESD),left ventricular end diastolic diameter(LVEDD),left ventricular ejection fraction(LVEF),related parameters of hemodynamic characteristic indexes include cardiac output(CO),cardiac output index(CI),stroke volume(SV),stroke volume index(SVI),and related parameters of left ventricular function and hemodynamic characteristics in patients with different hypertension grades were compared and analyzed.Result:Compared with the control group,the index parameters of LAD,LADI,LVESD and LVEDD in the study group were significantly increased,and the index parameters of LVEF was significantly decreased(P<0.05).Compared with the control group,the index parameters of CO,CI,SV and SVI in the study group decreased significantly(P<0.05).The LAD,LADI,LVESD and LVEDD parameters of gradeⅢhypertension patients were significantly higher than those of gradeⅠandⅡ,and the LVEF parameters were significantly lower than those of gradeⅠandⅡ(P<0.05).The LAD,LADI,LVESD and LVEDD parameters of gradeⅡhypertension patients were significantly higher than those of gradeⅠ,and the LVEF parameters was significantly lower than those of gradeⅠ(P<0.05).The parameters of CO,CI,SV and SVI in patients with gradeⅢhypertension were significantly lower than those of gradeⅠandⅡ,with statistical significances(P<0.05).The parameters of CO,CI,SV and SVI in patients with gradeⅡhypertension were significantly lower than those of gradeⅠ,with statistical significances(P<0.05).Conclusion:Echocardiography can effectively evaluate the left ventricular function and hemodynamics of patients,and has certain clinical application value.
