摘　　要：目的 探讨高血压左室肥厚伴左心力衰竭患者采用心脏彩色多普勒超声(彩超)诊断的效果。方法 选取500例高血压左室肥厚伴左心力衰竭患者作为观察组,另选取500例健康体检者作为对照组。两组均实施心脏彩超检查。比较两组左室收缩末期内径(LVESD)、舒张压、左室舒张末期内径(LVEDD)、收缩压、左室射血分数(LVEF)、左室质量(LVM)、左室短轴缩短率(LVFS)、左室质量指数(LVMI)及心脏彩超二尖瓣口舒张晚期最大血流速度(A峰值)、二尖瓣口舒张早期最大血流速度(E峰值)、E/A值。结果 观察组舒张压(92.14±4.15)mm Hg(1 mm Hg=0.133 kPa)、收缩压(154.32±7.26)mm Hg高于对照组的(76.48±4.32)、(120.35±7.47)mm Hg,LVESD(32.14±2.13)mm、LVEDD(52.13±3.19)mm大于对照组的(29.38±2.05)、(48.67±3.54)mm,差异有统计学意义(P<0.05)。观察组LVEF(55.35±2.05)%低于对照组的(67.35±2.19)%,LVM(252.34±7.29)g、LVFS(33.05±2.16)%和LVMI(143.29±4.15)g/m^(2)高于对照组的(207.54±7.46)g、(30.21±3.34)%、(105.43±4.32)g/m^(2),差异有统计学意义(P<0.05)。观察组A峰值(73.42±6.59)m/s高于对照组的(64.87±5.86)m/s,E峰值(55.76±7.12)m/s、E/A值(0.79±0.20)低于对照组的(81.42±7.23)m/s、(1.32±0.23),差异有统计学意义(P<0.05)。结论 高血压左室肥厚伴左心力衰竭患者临床诊断过程中心脏彩超的应用效果明显,其能够将心脏相关指标和心脏内结构等显示出来,对于疾病的诊治有利,同时也可以为临床诊治提供数据参考,值得临床进一步采纳与推广。Objective To discuss the effect of color Doppler echocardiography in hypertensive patients with left ventricular hypertrophy and left heart failure.Methods 500 cases of hypertensive patients with left ventricular hypertrophy and left heart failure were selected as the observation group,and another 500 healthy subjects were selected as the control group.Both groups underwent color Doppler echocardiography examination.Both groups were compared in terms of left ventricular end-systolic diameter(LVESD),left ventricular end-diastolic diameter(LVEDD),systolic blood pressure,left ventricular ejection fraction(LVEF),left ventricular mass(LVM),left ventricular short-axis shortening rate(LVFS),left ventricular mass index(LVMI),early diastolic peak flow velocity of mitral valve(E-peak value),late diastolic peak flow velocity of mitral valve(A-peak value)and E/A value.Results Diastolic blood pressure of(92.14±4.15)mm Hg(1 mm Hg=0.133 kPa)and systolic blood pressure of(154.32±7.26)mm Hg in the observation group were higher than those of(76.48±4.32)and(120.35±7.47)mm Hg in the control group;LVESD of(32.14±2.13)mm and LVEDD of(52.13±3.19)mm in the observation group were higher than those of(29.38±2.05)and(48.67±3.54)mm in the control group;the differences were statistically significant(P<0.05).LVEF of(55.35±2.05)%in the observation group was lower than that of(67.35±2.19)%in the control group;the observation group had LVM of(252.34±7.29)g,LVFS of(33.05±2.16)%and LVMI of(143.29±4.15)g/m^(2),which were higher than those of(207.54±7.46)g,(30.21±3.34)%and(105.43±4.32)g/m2 in the control group;the differences were statistically significant(P<0.05).A-peak value of(73.42±6.59)m/s in the observation group was higher than that of(64.87±5.86)m/s in the control group;E-peak value of(55.76±7.12)m/s and E/A value of(0.79±0.20)in the observation group were lower than those of(81.42±7.23)m/s and(1.32±0.23)in the control group;the differences were statistically significant(P<0.05).Conclusion The application of color Doppl
