近二十多年来,微循环研究进展较快。本文仅就老年内科常见病的微循环改变作一简要文献综述。 一、老年心血管病的微循环改变 (一)高血压 高血压患者的血管反应及运动改变早被重视,高血压的甲皱及球结膜微循环改变主要为细动脉及毛细血管径缩小,异形管绊增多并有纤曲,有的可出现微血管瘤和乳头下静脉丛,血流速度减慢,红细胞聚集。李氏对107例老年高血压患者进行球结膜与甲皱微循环观察,同时测定血清胆固醇,β-脂蛋白及甘油三酯,发现血脂
Nearly two decades, microcirculation research is progressing rapidly. This article only on microcirculation of common diseases in senile medicine to make a brief summary of the literature. First, changes in microcirculation of elderly cardiovascular disease (a) of the patients with hypertension Hypertensive vascular response and motor changes have long been valued, high blood pressure of the nail fold and conjunctival microcirculation changes mainly arterioles and capillary diameter narrow, shaped Tube stubs increase and have fibrillation, and some may appear capillaries and papillary venous plexus, blood flow slows down, erythrocyte aggregation. Lee on 107 cases of elderly patients with hypertensive conjunctival and nail fold microcirculation observed at the same time, serum cholesterol, β-lipoprotein and triglyceride, found that lipid
