An increase in peripheral vascular resistance at rest is not routinely observed in healthy older persons, but often associated with increased stiffness of central elastic arteries, as hallmarks of aging effects on the vasculature, referred to as early vascular aging (EVA). In clinical practice, the increased arterial stiffness translates into increased brachial and central systolic blood pressure and corresponding pulse pressure in subjects above 50 years of age, as well as increased carotid-femoral pulse wave velocity (c-f PWV), a marker of arterial stiffness. A c-f PWV value ≥ 10 m/s is currently defined as a threshold for increased cardiovascular risk, based on consensus statement from 2012. Prevention and treatment strategies include a healthy lifestyle and the control of risk factors via appropriate drug therapy to achieve vascular protection related to EVA. New drugs are under development for vascular protection, for example the selective Angiotensin II (AT2) receptor agonist called compound 21. One target group for early intervention could be members of risk families including subjects with early onset cardiovascular disease.
在健康的老年人中,静息时外周血管阻力增加并不常见,但常与中央弹性动脉僵硬度增加有关,这是血管老化效应的标志,称为早期血管老化(EVA)。在临床实践中,动脉僵硬度的增加导致 50 岁以上人群的肱动脉和中心收缩压以及相应的脉压增加,以及颈动脉-股动脉脉搏波速度(c-f PWV)增加,这是动脉僵硬度的一个标志物。目前,根据 2012 年的共识声明,c-f PWV 值≥10m/s 被定义为心血管风险增加的阈值。预防和治疗策略包括健康的生活方式和通过适当的药物治疗控制危险因素,以实现与 EVA 相关的血管保护。目前正在开发用于血管保护的新药,例如称为化合物 21 的选择性血管紧张素 II(AT2)受体激动剂。一个早期干预的目标群体可能是包括心血管疾病早发患者在内的高危家族成员。
