Attenuated radial augmentation index is associated with successful long-term antihypertensive treatment.
Pulse wave analysis was performed in apparently normal volunteers (n=164) and in essentially hypertensive patients without cardiovascular complications (n=171) using a newly developed non-invasive pulse wave measurement device (HEM-9010AI). Our results suggest that early wave reflections measured by radial augmentation index (AIr) are enhanced in volunteers with systolic blood pressure (SBP) >or= 160 mm Hg compared with the volunteers with their SBP<160 mmHg (98+/-18 vs 88+/-12, P<0.05). Furthermore, AIr is lower in hypertensive patients with long-term antihypertensive treatment than in those with short-term treatment (84+/-10 vs 89+/-13, P<0.01).
