Blood pressure and pulse wave velocity as metrics for evaluating pathologic ageing of the cardiovascular system.

The influence of chronological ageing on the components of the cardiovascular system is of fundamental importance for understanding how hemodynamics change and the cardiovascular risk increases with age, the most important risk marker. An increase in peripheral vascular resistance associated with increased stiffness of central elastic arteries represents hallmarks of this ageing effect on the vasculature, referred to as early vascular ageing (EVA). In clinical practice, it 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 threshold for increased risk according. Improved lifestyle and control of risk factors via appropriate drug therapy are of importance in providing vascular protection related to EVA. One target group might be members of risk families including subjects with early onset cardiovascular disease.
