[摘要]目的 分析心臟彩超對高血壓左室肥厚伴左心衰竭患者的臨床診斷價值。方法 選取2014年7月～2016年7月于我院就診的58例高血壓左室肥厚伴左心衰竭患者作為觀察組，另選同期來我院體檢的58例健康人群為對照組。兩組患者均進行心臟彩超檢查，比較兩組的舒張壓、收縮壓、左室重量（LVM）、左室質量指數（LVMI）、左室短軸縮短分數（LVFS）、左室舒張末期內徑（LVEDD）、左室收縮末內徑（LVESD）、左室射血分數（LVEF）、左房內徑（LAD）、二尖瓣口舒張早期最大血流速度（E）/二尖瓣舒張早期最大運動速度（A）（E/A）。結果 觀察組的收縮壓、舒張壓以及LVEDD參數均顯著高于對照組，差異有統計學意義（P<0.05）。觀察組的LVM、LIMI、LVFS及LVEF指標均顯著高于對照組，差異有統計學意義（P<0.05）。觀察組的A峰值顯著高于對照組，E峰值及E/A比值顯著低于對照組，差異有統計學意義（P<0.05）。Ⅲ級患者的LAD、LVEDD、E/Ea顯著高于Ⅱ級，LVEF顯著低于Ⅱ級，差異有統計學意義（P<0.05）。結論 心臟彩超能動態顯示出心腔構造、心臟搏動以及血液流動，可準確地對心臟功能進行判斷，且具有無創傷，能重復操作等優點，可以作為患者早期病情判斷的依據。

[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.
