摘要
回顾性分析 1985~ 1990年 5 437例连续检测的高血压者超声心动图资料 ,以左心室重量指数 (LVMI)作为诊断左心室肥厚 (LVH)的指标 ,男性 >12 5 g/m2 ,女性 >12 0 g/m2 。结果表明 ,LVH检出率为 31.6 % ,男女性之间无显著性差异 ;严重程度分级 ,轻、中、重LVH分别占 6 6 .3 % ,2 1.7%与 12 .0 % ;结构分型 ,不对称性室间隔肥厚、对称性肥厚、扩张性肥厚分别占 2 8.1% ,34.0 %与 37.9% ;如以室间隔与左室后壁厚度实测值为诊断指标 ,虽然阳性符合率很高 (86 .7% ) ,但有较高假阳性率(41.0 % )。
Echocardiograms of 5437 patientswith hypertension examined consecutively in our institute during 1985~1990 were retrospectively analysed,using left ventricular mass index(LVMI) as the parameter of left ventricular hypertrophy(LVH).It was found that the prevalence of LVH was 31.6% in all hypertensives with the cut offs for LVMI>125 g/m 2 in male,>120 g/m 2 in female with no significant difference in the prevalence of LVH between male and female.The proportions for the degree of LVH were 66.3%,21.7% and 12.0% for mild,moderate and severe LVH respectively;for the type of LVH,asymmetric septum hypertrophy(ASH) accounted for 28.1%,concentric hypertrophy(CH),34.0% and dilating hypertrophy,(DH) 37.9%.The true positive rates of LVH were as high as 86.7%,but false positive rates reached 41.0% if using interventricular septum thickness(IVST) and posterior wall thickness(PWT) as the parameter of LVH,compared with LVMI.
