Abstract

Inhibition of the renin-angiotensin system may have effects on vascular structure and function beyond the effects on blood pressure (BP) reduction. We studied the ability of a single arm cuff oscillometric method (Arteriograph, TensioMed, Hungary) to assess effects of antihypertensive treatment on BP and arterial stiffness. Furthermore, this technique was compared to pulse wave analysis and applanation tonometry (SphygmoCor, AtCor Medical, Australia). Brachial and aortic BP, augmentation index (AIx), and carotid-femoral pulse wave velocity (PWV) was simultaneously assessed by both techniques in 71 untreated hypertensive patients. Thereafter, 58 completed double-blind randomized treatment for 12 weeks with ramipril or doxazosin. Treatment (assessed by the Arteriograph) reduced aortic more than brachial systolic BP (-13.2 vs. -11.2 mm Hg; p = .002) and improved all indices of arterial stiffness. This greater reduction in aortic to brachial systolic BP was more marked by ramipril than by doxazosin (-20.9 and -17.1 vs. -4.3 and -4.2 mm Hg; p = .006), with a similar trend for AIx (-6.2 vs. -2.2%; p = .058). Both devices showed correlations for aortic and brachial systolic and diastolic BP and AIx (r = 0.75-0.86, all p < .001), while...Continue Reading
