    • Abstract:
      The radial artery compliance may be paradoxically increased in untreated arterial hypertension. However, the effect of blood pressure normalization on the radial artery compliance is not well known. We performed a cross-sectional study in order to investigate the effects of blood pressure control on the radial artery diameter and compliance (echotracking and digital photoplethysmography) by comparing these variables in a group of untreated hypertensive patients and in another group of adequately treated hypertensive patients as well as in a group of healthy normotensive subjects. All groups were sex- and age-matched. Radial artery internal diameter was increased in both untreated hypertensive patients and effectively treated hypertensive patients comparatively to controls. Cross-sectional compliance and volumic distensibility were not different between groups. As compared to controls (2.85 +/- 0.39 x 10(-3) mm2 x mm Hg(-1) and 0.42 +/- 0.05 x 10(-3) mm Hg(-1)), isobaric (100 mm Hg) compliance and distensibility were significantly increased in untreated hypertensive patients (4.46 +/- 0.44 and 0.65 +/- 0.07, P < .01) but not significantly different in treated hypertensive patients (3.19 +/- 0.33 and 0.45 +/- 0.04, P = NS). The results of this cross-sectional study suggest that compliance abnormalities of the radial artery, but not internal diameter changes may be reversed by effective therapeutic control of blood pressure in arterial hypertension.
