微循环是身体最小的功能单位,它不断地进行物质交换以保持机体内环境的动态平衡。维持细胞和组织的生存并保证脏器的正常功能。多种病理刺激均可使微循环受到影响并进而引起病理生理上的连锁反应;所以微循环是涉及多学科研究的重要领域,近二十多年来,微循环的基础研究进展较快,从而带动了临床研究的发展。本文就老年内科主要常见病的国内外概况作一简要综述。一、老年心血管病的微循环改变: 1.高血压:高血压患者的血管反应性及运动性改变早就引起医学界的重视,近些年来的研究表明高血压的甲皱及球结膜微循环改变主要为细动脉、毛细血管的管径缩小,异形管绊增多并有迂曲,有的可出现微
Microcirculation is the smallest functional unit of the body that constantly exchanges material to maintain the homeostasis of the body. Maintain the survival of cells and tissues and ensure the normal function of organs. A variety of pathological stimuli can affect the microcirculation and thus cause a pathophysiological chain reaction; so microcirculation is an important area involving multidisciplinary research, the basic research of microcirculation has progressed rapidly in recent twenty years, thus Driven the development of clinical research. This article gives a brief overview of the general situation of common diseases in geriatrics at home and abroad. First, the microcirculation of elderly cardiovascular disease changes: 1. Hypertension: Vascular reactivity and exercise changes in patients with hypertension has long been caused by the medical profession’s attention, in recent years, studies have shown that high blood pressure nail and conjunctival micro Cyclic changes are mainly arterioles, capillary diameter reduced, shaped tube trip increased and tortuous, and some may appear micro
