摘要目的研究高血压病患者左室舒张功能的变化。方法二维超声检测68例高血压病患者（左室肥厚33例，非肥厚组35例）的左房大小、室间隔厚度、左室后壁厚度，多普勒测定二尖瓣血流频谱及左室等容舒张时间，并与同年龄正常人对照。结果高血压组与对照组比较：左房明显扩大，室间隔及左室后壁明显增厚，二尖瓣口舒张早期充盈速度及其流速积分显著减小，舒张晚期充盈速度及其流速积分显著增高，IVRT显著延长。高血压组中，左室肥厚组与非肥厚组比较：肥厚组左房扩大，室间隔及左室后壁增厚，E峰、Ei减小，A峰、Ai增高，IVRT延长均较非肥厚组明显。结论高血压病患者存在左室舒张功能异常，左室肥厚者舒张功能的损害更加严重。 Objective To study the LV diastolic function in essential hypertension patients. Methods 68 cases of two - dimensional uhrasonography in patients with essential hypertension （ left ventricular hypertrophy in 33 cases ,35 cases of non - hypertrophy group） of the left atrial size, interventricular septum thickness, left ventricular posterior wall thickness, doppler determination of the second mitral valve flow pattern and left ventricular isovolumic relaxation time, and normal controls in the same age. Results The transverse and longitudinal dimention of LA in EH were larger than that in NT, IVST and LVPET were significantly increased with that in NT,the E, Ei of EH patients were lower than that in NT, the A, Ai of EH patients were higher than that in NT. IVRT of EH patients were lower than NT. the E, Ei of hypertension patients in LVH were lower than that in non - LVH, the A, Ai of hypertension patients were higher than that in non - LVH. IVRT of hypertension patients in LVH were lower than that in non - LVH. Conclusion Left ventricular diastolic disfunction happens in hypertension patients. Left ventricular diastolic disfunction of hypertension patients with LVH are more severe.
