【摘要】 通过计算机辅助的声学组织密度定量新技术,对28例向心性肥厚的高血压患者和32例正常人的左室心肌组织特征进行研究,以评价超声诊断高血压左室肥厚心肌纤维化的可行性。结果显示:高血压组二尖瓣水平和乳头肌水平短轴切面的整体灰阶均值及优势灰阶均值均高于正常组(P<0.01);高血压组二尖瓣水平四个节段的灰阶均值高于正常组(P<0.05);乳头肌水平前壁和后壁灰阶均值高于正常组(P<0.05)。更多还原

【Abstract】 To evaluate the myocardial fibrosis in the hypertensive left ventricular hypertrophy (LVH), myocardial echodensity in two-dimensional image were investigated in 28 patients with concentric hypertensive LVH and 32 normal subjects by using the computer assistant imaging analysis system, The results showed that the general mean gray-scale and the superiority value in hypertensive patients were higher than those in the normal subjects on the short-axis views at the papillary level and the mitral level (P<0. 01) ;The mean gray-scale in the hypertensive patients were greater than that in the normal subjects at all four segments at the mitral level,whereas greater only at the anterior and posterior walls at the papillary level(P< 0.05)更多还原
