红细胞变形能力(red cell deformability)是指红细胞能通过比自身直径小的微循环血管的能力。作者等以核孔滤膜法测定65例高血压病患者的红细胞变形能力,发现各期患者较健康对照组均有红细胞变形能力降低,尤以第Ⅱ、Ⅲ期患者降低更为明显。健康组30例的红细胞过滤指数(erythrocyte f(?)terability index,EFI)为44.2±10,Ⅰ期高血压病20例 Red cell deformability refers to the ability of red blood cells to pass through microcirculation vessels smaller in diameter than themselves. The authors determined the erythrocyte deformability of 65 patients with essential hypertension by nuclear pore filter and found that erythrocyte deformability decreased in all patients compared with healthy controls, especially in patients with stage II and III. The erythrocyte f (?) Terability index (EFI) was 44.2 ± 10 in 30 healthy people and 20 patients with stage Ⅰ hypertension
