Abstract: Objective: Pulse pressure (PP) is a complex physiologic trait affected by many variables, including LV contractility (reflected by stroke volume), arterial stiffness, and central-to-brachial amplification.The impact of age on the relationship between stroke volume and central or brachial PP has not been investigated.

Methods: 3765 untreated hypertensive adults (men 56%, age 50 ± 12 years) underwent 24-hour ambulatory BP monitoring (SpaceLabs) and M-mode echocardiography. In a subset of 982 subjects in whom central PP was measured by applying a transfer function to radial pulse wave (SphygmoCor), we also estimated central office (or 24 h) PP by regression equations based on office (or 24 h) PP and MAP, heart rate, age, height and sex (R2 = 0.92 between estimated and measured central PP).The same equations were then applied to the original population to obtain estimated central PP.

Results: Stroke volume had a significant direct association with both brachial and central 24 h PP up to the age of 39 years. The above relationship weakened with age and became mostly non-significant after the age of 40 (all r < 0.10). Similar, although weaker, trends were observed for office PP (both brachial and central).

Conclusions: 24-h PP has a strong direct association with LV stroke volume in the young only, and might more exclusively depend on arterial stiffness later in life. Since the above relationship was also observed with estimated central PP, it may not depend on PP amplification. The “young” and “old” pathophysiological patterns of PP may help to explain the increasingly adverse prognostic value of PP observed with advancing age.
