[摘要]目的 分析心臟彩超对高血压左室肥厚伴左心衰竭患者的临床诊断价值。方法 选取2014年7月～2016年7月于我院就诊的58例高血压左室肥厚伴左心衰竭患者作为观察组，另选同期来我院体检的58例健康人群为对照组。两组患者均进行心脏彩超检查，比较两组的舒张压、收缩压、左室重量（LVM）、左室质量指数（LVMI）、左室短轴缩短分数（LVFS）、左室舒张末期内径（LVEDD）、左室收缩末内径（LVESD）、左室射血分数（LVEF）、左房内径（LAD）、二尖瓣口舒张早期最大血流速度（E）/二尖瓣舒张早期最大运动速度（A）（E/A）。结果 观察组的收缩压、舒张压以及LVEDD参数均显著高于对照组，差异有统计学意义（P<0.05）。观察组的LVM、LIMI、LVFS及LVEF指标均显著高于对照组，差异有统计学意义（P<0.05）。观察组的A峰值显著高于对照组，E峰值及E/A比值显著低于对照组，差异有统计学意义（P<0.05）。Ⅲ级患者的LAD、LVEDD、E/Ea显著高于Ⅱ级，LVEF显著低于Ⅱ级，差异有统计学意义（P<0.05）。结论 心脏彩超能动态显示出心腔构造、心脏搏动以及血液流动，可准确地对心脏功能进行判断，且具有无创伤，能重复操作等优点，可以作为患者早期病情判断的依据。

[Abstract]Objective To analyze the clinical diagnostic value of cardiac color Doppler ultrasonography in hypertension-induced left ventricle hypertrophy patients with left heart failure.Methods From July 2014 to July 2016，58 hypertension-induced left ventricle hypertrophy patients with left heart failure treated in our hospital were selected as the observation group.Another group of 58 healthy people visiting our hospital for physical examinations were selected as the control group during the same period.Both groups were provided with cardiac color Doppler ultrasonography.Indexes of diastolic blood pressure （DBP），systolic blood pressure （SBP），left ventricular weight （LVM），left ventricular mass index （LVMI），left ventricular fractional shortening （LVFS），left ventricular end-diastolic diameter （LVEDD），left ventricular end-systolic diameter （LVESD），left ventricular ejection fraction （LVEF），left atrial diameter （LAD），maximal blood flow velocity of opening of mitral valve at early diastolic stage （E）/maximal speed of movement of mitral valve at early diastolic stage （A） were compared between the two groups.Results In the observation group，the SDP，SBP，and LVEDD were all much higher in comparison with those in the control group，with statistical differences （P<0.05）.The indexes of LVM，LVMI，LVEF and LVFS were significantly higher in the observation group compared with those in the control group，with statistical differences （P<0.05）.In the observation group，the peak value A was significantly higher than that in the control group，while the peak value E and E/A ratio were greatly lower than those in the control group，with statistical differences （P<0.05）.In patients with grade Ⅲ cardiac function，the indexes of LAD，LVEDD and E/A were significantly higher than those in grade Ⅱ，while LVEF was much lower than that of grade Ⅱ，with statistical differences （P<0.05）.Conclusion Cardiac color Doppler ultrasound can dynamically display the structure of cardiac cavity，heart beat and blood flow as well as accurately evaluate the cardiac function at advantages of no trauma and repeatable performance，which can be considered as a basis for early judgment for patients′ disease condition.
