Hypertension is the leading cause of death in the elderly in Western countries. The Authors remark that hypertension is not only a purely hemodynamic phenomenon, but is a multifaceted disease frequently associated with metabolic disorders in the elderly. Among the latter, hyperinsulinism could be the linking pathogenetic factor with atherosclerosis progression. Then the Authors suggest a unitary pathogenetic hypothesis of hypertension and atherosclerosis. The crucial points are the inborn alteration of cellular sodium transport systems and the modulating action of environmental factors, first of all insulin. According to this hypothesis, the goal of the management of elderly hypertensives is the prevention of the fatal or invalidant cerebro- and cardiovascular event. To follow a good "pathogenetic" treatment of elderly hypertension and atherosclerotic process evolution, the first step is a dietetic approach avoiding acute load of sodium and lipids. Furthermore, the pharmacological treatment with calcium antagonists and ACE inhibitors is respectful of associated metabolic disorder and positively modulate the cellular sodium transport systems activity.
高血压是西方国家老年人死亡的主要原因。作者指出,高血压不仅是一种纯粹的血液动力学现象,而且是一种多方面的疾病,在老年人中常与代谢紊乱相关。在这些代谢紊乱中,高胰岛素血症可能是与动脉粥样硬化进展相关的致病因素。然后作者提出了高血压和动脉粥样硬化的统一致病假说。关键点是细胞钠转运系统的先天性改变以及环境因素的调节作用,首先是胰岛素。根据这一假说,老年高血压患者治疗的目标是预防致命或致残的脑血管和心血管事件。为了对老年高血压和动脉粥样硬化进程演变进行良好的“致病”治疗,第一步是采取饮食方法,避免钠和脂质的急性负荷。此外,使用钙拮抗剂和血管紧张素转换酶抑制剂进行药物治疗,既考虑到了相关的代谢紊乱,又能积极调节细胞钠转运系统的活性。
