This review outlines the latest methods and innovations for assessing arterial stiffness, along with their respective advantages and disadvantages. Furthermore, we present compelling evidence indicating a recent growth in research focused on assessing arterial stiffness using photoplethysmography (PPG) and propose PPG as a potential tool for assessing vascular ageing in the future. Blood vessels deteriorate with age, losing elasticity and forming deposits. This raises the likelihood of developing cardiovascular disease (CVD), widely reported as the global leading cause of death. The ageing process induces structural modifications in the vascular system, such as increased arterial stiffness, which can cause various volumetric, mechanical, and haemodynamic alterations. Numerous techniques have been investigated to assess arterial stiffness, some of which are currently used in commercial medical devices and some, such as PPG, of which still remain in the research space.
本文概述了评估动脉僵硬度的最新方法和创新，以及它们各自的优缺点。此外，我们提出了令人信服的证据，表明最近使用光体积描记法（PPG）评估动脉僵硬度的研究有所增加，并提出 PPG 可能成为未来评估血管老化的一种潜在工具。血管随年龄增长而恶化，失去弹性并形成沉积物。这增加了患心血管疾病（CVD）的可能性，CVD 是全球广泛报道的主要死亡原因。衰老过程会引起血管系统的结构改变，例如动脉僵硬度增加，这可能导致各种体积、力学和血液动力学的改变。已经研究了许多技术来评估动脉僵硬度，其中一些目前已用于商业医疗设备，而另一些，如 PPG，则仍处于研究阶段。
