高血压病是一种常见病多发病。由于其发病机理尚未完全阐明,临床多按其血压高低分为第一、二、三期,其治疗方案亦是根据分期选用不同的降压药物。近年来据多方面的研究,对其发病机理及用药方法都有一些新的进展,本文拟将这方面资料介绍于下,供作参考。一、高血压病的分型在高血压病发病的多种因素中,至少有两个系统起着重要调节作用,一是神经系统,其中包括中枢神经系统、植物神经系统等;二是肾素——血管紧张素——醛固酮系统。按血液动力学研究资料表明:高血压病的外周阻力、心输出量、有效血容量、肾素——血管紧张素——醛固酮系 Hypertension is a common disease frequently-occurring disease. Because of its pathogenesis has not been fully elucidated, according to the clinical level of their blood pressure is divided into the first, second and third period, the treatment options are based on the phased selection of different antihypertensive drugs. According to many researches in recent years, some new progress has been made on its pathogenesis and medication methods. This article intends to introduce this information for reference. First, the classification of hypertension in the pathogenesis of hypertension, a variety of factors, at least two systems play an important regulatory role, one is the nervous system, including the central nervous system, autonomic nervous system, etc .; the second is renin Angiotensin - aldosterone system. According to the hemodynamic study data show that: peripheral resistance to hypertension, cardiac output, effective volume, renin - angiotensin - aldosterone
