摘　　要：目的 :运用复合超声技术诊断不同程度高血压以直观患者心血管解剖结构和功能的病变状况。方法 :采用复合超声心动图随机检测高血压患者 52例及正常志愿者 64例 ,检测内容 :室间隔厚度 (IVST)及左室后壁厚度 (LVPWT)、收缩期运动幅度 (SA)、舒张早期弛张速度 (DV)、各房室横径及长径、左右房室瓣口舒张期血流参数、肺静脉收缩期及舒张期血流参数、左室 (LV)收缩功能常规参数。结果 :全部高血压患者 :1 .室间隔与左室后壁平均厚度分别增厚约 0 .40 cm和 0 .42 cm (P<0 .0 0 1 ) ;2 .室间隔与左室后壁平均收缩幅度分别增大 0 .0 8cm和 0 .2 8cm (P<0 .0 1 ) ;3.左心房明确扩大 (P<0 .0 0 1 ) ;4.左室收缩功能各项检测参数均高于正常人 (P<0 .0 5～ 0 .0 1 ) ;5.平均值为 72 .85%的左室射血分数与左室壁收缩期幅度的增强呈高度相关 (r=0 .91 ,P<0 .0 0 0 1 ) ;6.左室内径存在扩大的趋势 (P<0 .0 1 ) ;7.左室舒张末期容量及心输出量均有增大的趋势 (P<0 .0 5～ 0 .0 0 1 ) ;8.左室内径与左室舒张末期容量的增大两者间呈高度相关 (r=0 .93,P<0 .0 0 0 1 ) ;9.2 2例患者合并升主动脉扩张 ,2例合并腹主动脉瘤 ,1 7例合并肺动脉高压。结论 :注重客观评价高血压人群的疾病状态。复合超声心动图能够准确分析高血压?Objective:To evaluate the cardiac structure and functional changes of patients with hypertension.Methods:Fifty two patients with hypertension and 64 normal subjects were studied by complex echocardiography.The measrements were as follows:IVST,LVPWT,transverse and longitudinal dimentions of LA,RA,LV and RV,systolic motion amplitude(SA)and early diastolic relaxant velocity(DV).The blood flow parameters were:left and right atrioventricular annular flow,syetolic and diastolic flows of pulmonary vein and systolic functions of LV.Results:In all patients with hypertension:(1) Mean IVST and LVPWT were significantly increased as compared with the normal,almost to 0 40 cm and 0 42 cm respectively( P <0 001);(2)Mean SAs of IVS and LVPW were increased to 0 08 cm and 0 28 cm respectively( P <0 01);(3)LAD was larger than that of the normal( P <0 001);(4)All data from systolic function of LV were greater than those of the normal ( P <0 05～0 01);(5)Mean value of LVEF(72 85%) was correlated well with increased SA of left ventricular wall( r =0 91, P <0 0001);(6)LVD was tended to larger ( P <0 001);(7)End diastolic volume(EDV)and CO of LV were tended to be increased( P <0 05～0 01);(8)There was good correlation between increased LV D and EDV( r =0 93, P <0 0001);(9)Ascending aorta (AAO)enlargment in 22 cases,abdominal aorta aneurysm in 2 cases and pulmonary hypertention in 17 cases were found.Conclusions:We should pay attention to the objective evaluation of hypertensive disease.Complex echocardiography is an effective and practical method to estimate cardiac function and structural changes in patients with hypertension.It will be a main basis for treatment and controlling of hypertensive course evolution.
