[摘要]意图 剖析心臟彩超对高血压左室肥厚伴左心衰竭患者的临床确诊价值。办法 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调查组，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查看，比较两组的舒张压、缩短压、左室分量（LVM）、左室质量指数（LVMI）、左室短轴缩短分数（LVFS）、左室舒张晚期内径（LVEDD）、左室缩短末内径（LVESD）、左室射血分数（LVEF）、左房内径（LAD）、二尖瓣口舒张前期最大血流速度（E）/二尖瓣舒张前期最大运动速度（A）（E/A）。成果 调查组的缩短压、舒张压以及LVEDD参数均明显高于对照组，差异有统计学含义（P<0.05）。调查组的LVM、LIMI、LVFS及LVEF目标均明显高于对照组，差异有统计学含义（P<0.05）。调查组的A峰值明显高于对照组，E峰值及E/A比值明显低于对照组，差异有统计学含义（P<0.05）。Ⅲ级患者的LAD、LVEDD、E/Ea明显高于Ⅱ级，LVEF明显低于Ⅱ级，差异有统计学含义（P<0.05）。定论 心脏彩超能动态显示出心腔结构、心脏搏动以及血液活动，可精确地对心脏功用进行判别，且具有无创伤，能重复操作等长处，能够作为患者前期病况判别的根据。

[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.
