摘要
采用超声心动图对高血压病患者进行检测，以观察不同病程对左室肥厚（LVH）及功能参数的影响。高血压甲组（病程≤10年）及乙组（病程＞10年）的室间隔厚度（IVSTd），左室后壁厚度（PWPd）、左室舒张期内径（LVEDD）和左室重量指数（LVWI）均明显高于血压正常组。高血压乙组的IVSTd，LVEDD和LVWI亦明显高于甲组。高血压组IVH总的检出率为40．8％。甲、乙两组分别为33．3％和48．9％，LVH类型在两组间无明显差别。高血压甲、乙两组的左室舒张功能受损，主要表现为二尖瓣舒张晚期血流速度峰值（A）增加,E／A比值减少（E为早期峰值）。高血压乙组的左室射血分数（LVEF）较正常血压组低，甲组与正常血压组无差别。结果揭示，高血压病程是影响LVH和左室功能的一个重要因素。
Hypertensive patients in different stages were examined by echocardiography to study the effects of the course of hypertension on the parameters of LVH and left ventricular function. Compared with the normal blood pressure group, IVSTd,PWTd, LVEDD,and LVWI were higher in hy pertensive group A(≤10 years ) and group B (> 10 years). Values of IVSDd,LVEDD and LVWI were higher in group B than those in group A. Incidence of LVH was 40. 8K in the whole hypertensive group and 33. 3% and 48. 9% in groups A and B,respectively,with no difference in the type of LVH. Diastolic.function of LV was damaged in hypertensive groups A and B,mainfested by higher A value and lower E/A. LVEF was lower in hypertensive group B. The results suggest that the course of hypertension is an important risk factor for LVH and LV functions.
