In 78 hypertensive patients, rAI correlates inversely with pulse rate (PR; r = \u22120.57, P &lt; .001), but baPWV does not. A weak correlation between rAI and systolic blood pressure (SBP) is observed (r = 0.28, P &lt; .05). rAI has no significant correlation with diastolic blood pressure (DBP). In contrast, baPWV correlates positively with both SBP (r = 0.54, P &lt; .001) and DBP (r = 0.43, P &lt; .001). In 56 of these patients, baPWV correlates with the diastolic parameters\u2014the mitral E\/A ratio (r = \u20140.35, P &lt; .01), pulmonary vein S\/D ratio (r = 0.41, P &lt; .01), and deceleration time (r = 0.28, P &lt; .05)\u2014by echocardiography, but AI.P75 (rAI corrected for PR 75 bpm because of PR dependence) does not. Therefore, for detection of diastolic dysfunction, baPWV may be more sensitive than rAI.<\/jats:p>","DOI":"10.1177\/0003319707306299","type":"journal-article","created":{"date-parts":[[2008,4,3]],"date-time":"2008-04-03T20:25:56Z","timestamp":1207254356000},"page":"421-426","source":"Crossref","is-referenced-by-count":20,"title":["Augmentation
