实时三维超声心动图对高血压患者左心功能的分析

目的：探讨实时三维超声心动图评价高血压患者左心功能的能力。方法选取60例高血压患者为观察组,60例健康患者为对照组。使用实时三维超声心动图测定所有患者的左心室后壁厚度（PWT）、左心房内径（LAD）、舒张期室间隔厚度（IVsT）、二尖瓣斜率、左心室射血分数（LVEF）和左心室短轴缩短率（Fs）,比较两组患者上述指标间的差异。结果观察组PWT、LAD、IVsT、LVEF和Fs均明显较对照组升高,差异均有统计学意义（均P〈0.05）,而二尖瓣斜率则明显小于对照组,差异有统计学意义（均P〈0.05）。结论实时三维超声心动图可以准确评价高血压患者左心功能,为临床诊断提供可靠依据。

Evaluation of left ventricular function in hypertensive patients by real-time three-dimensional echocardiography

Objective To investigate the evaluation of left ventricular function in hypertensive patients by real-time three-dimensional echocardiography. Methods 60 patients with hypertensive were selected to be the observation group while 60 health patients were selected to be the control group.the left ventricular posterior wall thickness （PWT）, left atrial diameter （LAD）, diastolic ventricular septal thickness （IVsT）, mitral valve slope, left ventricular ejection fraction （LVEF） and left ventricular short axis shortening rate （Fs） of all patients were measured by real-time three-dimensional echocardiography and were compared between the two groups. Results The PWT, LAD, IVsT and Fs were significantly higher than the control group, the differences were statistically significant （all P〈0.05）;while the mitral valve slope much smaller than the control group, the differences were statistically significant （all P〈0.05）. Conclusion The real-time three-dimensional echocardiography can exactly assess the left heart function in patients with hypertension and provide reliable basis for clinical diagnosis.
