Vascular aging is associated with profound changes in the structural properties of the arterial wall. Arterial hypertension, diabetes mellitus, and chronic kidney disease are the primary determinants of the loss of elasticity and reduced compliance of the vascular wall. Arterial stiffness is a key parameter for assessing the elasticity of the arterial wall and can be easily evaluated using non-invasive methods such as pulse wave velocity. Early assessment of arterial stiffness is critical, as its changes may precede the clinical manifestations of cardiovascular disease. With age, arterial walls become stiffer, leading to an increase in systolic blood pressure and an increased risk of cardiovascular events such as stroke, myocardial infarction, or heart failure. The gradual decrease in vascular elasticity is accompanied by remodeling of their structure, an increase in collagen fibers, and a decrease in elastin, which exacerbates the problem. In addition, the mechanical stress on the vascular wall, which increases with age, worsens its condition, provoking the formation of atherosclerotic plaques. Arterial stiffness, as an important biomarker of vascular aging, is also an indicator of increased cardiovascular risk, independent of other factors such as blood pressure or the presence of comorbidities. Therefore, timely diagnosis of arterial stiffness can help prevent serious complications and adjust treatment for patients at risk. Important are also preventive measures, including a healthy lifestyle, physical activity, and control of the underlying diseases that contribute to the acceleration of vascular aging processes. Moreover, the influence of endogenous and exogenous factors, such as diet, the presence of chronic diseases, and bad habits (in particular, smoking), contribute to the acceleration of these processes. Innovative diagnostic methods, such as magnetic resonance imaging (MRI) or ultrasound, allow detecting these changes at early stages and, accordingly, adapting treatment.
