Abstract:
BACKGROUND:Orthostatic hypotension, blood pressure (BP) variability, and arterial stiffness are three markers of cardiovascular risk beyond the average BP. However, the relationships between these three parameters are not well known. AIM:To examine the relationships between orthostatic hypotension, BP variability, and arterial stiffness. METHODS AND RESULTS:In the Three-City study, a sample of 1151 elderly participants (mean age = 80 ± 3 years) was screened for orthostatic hypotension, undertook home BP and pulse wave velocity (PWV) measurements. We performed logistic regression analyses to look at the associations between orthostatic hypotension and both day-to-day (D-to-D) BP variability quartiles and PWV quartiles. Orthostatic hypotension was detected in 210 participants who were more likely to be hypertensive, exhibit higher BP variability and have increased arterial stiffness. In the multivariate logistic regression analysis, the frequency of orthostatic hypotension increased by 20% with every quartile of D-to-D SBP variability and by 20% with every quartile of PWV. PWV and D-to-D BP variability were not associated. In stratified analysis, the use of beta-blocker changes these relationships: orthostatic hypotension was not associated to PWV anymore but its association with D-to-D SBP variability was apparently stronger. CONCLUSION:In this large sample of elderly individuals, orthostatic hypotension was independently associated with both BP variability and PWV. BP variability being more indicative of a baroreflex dysfunction and PWV being a marker of vascular ageing, these two components would participate to the orthostatic hypotension mechanisms.
