尽管有些研究结果表明急性脑血管病的发病率有下降趋势,但它目前仍是引起死亡和致残的主要原因。据欧美国家报告,脑血管病早期致残率约30％,约半数幸存者留有终身神经功能障碍。不过,近些年来,随着研究手段的不断改进,对脑缺血病理生理学有了新的认识,并出现了许多令人瞩目的治疗方法。本文仅就后者目前研究概况作一介绍。一、高血压疗法早期研究发现,脑缺血缺氧时,脑血管自动调节功能常受损,此时脑血流(CBF)随全身血压的变化而变化。并发现适时升高血压或增加心脏有效输出血量可促进缺血区侧枝循环
Although some studies show a declining trend in the incidence of acute cerebrovascular disease, it is still the leading cause of death and disability. According to reports from Europe and the United States, the early disability rate of cerebrovascular disease is about 30%, leaving about half of survivors with life-long neurological dysfunction. However, in recent years, with the continuous improvement of research methods, new understanding of pathophysiology of cerebral ischemia has emerged, and many remarkable treatments have emerged. This article only makes an introduction on the current research situation of the latter. First, the study found that the early treatment of hypertension, cerebral ischemia and hypoxia, cerebral vascular autonomic dysfunction often impaired, cerebral blood flow (CBF) with changes in systemic blood pressure changes. And found that timely raising blood pressure or increase the effective output of the heart can promote blood circulation collateral circulation
