influence of age on upper arm cuff blood pressure measurement
Hypertension, 2020Co-Authors: Dean S Picone, Martin G Schultz, Petr Otahal, Andrew J Black, Willem Jan W Bos, Chenhuan Chen, Haomin ChengAbstract:Blood pressure (BP) is a leading global risk factor. Increasing age is related to changes in cardiovascular physiology that could influence cuff BP measurement, but this has never been examined systematically and was the aim of this study. Cuff BP was compared with invasive aortic BP across decades of age (from 40 to 89 years) using individual-level data from 31 studies (1674 patients undergoing coronary angiography) and 22 different cuff BP devices (19 oscillometric, 1 automated auscultation, 2 mercury Sphygmomanometry) from the Invasive Blood Pressure Consortium. Subjects were aged 64±11 years, and 32% female. Cuff systolic BP overestimated invasive aortic systolic BP in those aged 40 to 49 years, but with each older decade of age, there was a progressive shift toward increasing underestimation of aortic systolic BP (P<0.0001). Conversely, cuff diastolic BP overestimated invasive aortic diastolic BP, and this progressively increased with increasing age (P<0.0001). Thus, there was a progressive increase in cuff pulse pressure underestimation of invasive aortic PP with increasing decades of age (P<0.0001). These age-related trends were observed across all categories of BP control. We conclude that cuff BP as an estimate of aortic BP was substantially influenced by increasing age, thus potentially exposing older people to greater chance for misdiagnosis of the true risk related to BP.

pulse wave analysis and hypertension evangelism versus scepticism
Journal of Hypertension, 2004Co-Authors: Bryan WilliamsAbstract:One hundred and thirty years ago, long before the routine use of blood pressure measurement, Mahmoud [1] advocated pulse wave analysis as a means of evaluating the functional integrity of the circulation. Enthusiasm for this approach subsequently diminished when Sphygmomanometry emerged as a simple and reliable means of recording peripheral blood pressure, which was in turn validated as a potent predictor of future cardiovascular morbidity and mortality.

Pulse wave analysis and hypertension: evangelism versus skepticism
2004Co-Authors: Bryan WilliamsAbstract:One hundred and thirty years ago, long before the routine use of blood pressure measurement, Mahmoud [1] advocated pulse wave analysis as a means of evaluating the functional integrity of the circulation. Enthusiasm for this approach subsequently diminished when Sphygmomanometry emerged as a simple and reliable means of recording peripheral blood pressure, which was in turn validated as a potent predictor of future cardiovascular morbidity and mortality. In recent years, there has been a resurgence of interest in the possibility of using alternatives to simple brachial blood pressure measurements to non-invasively evalu-ate circulatory function and predict cardiovascular risk. These indices, amongst others, include pulse pressure, pulse wave velocity and pulse wave analysis. Puls

'Minimal-change hypertensive retinopathy' and 'arterial pre-hypertension', illustrated via ambulatory blood-pressure monitoring in putatively normotensive subjects
International Ophthalmology, 1998Co-Authors: Pietro Cugini, Filippo Cruciani, Massimo Turri, Federico Regine, Francesco Gherardi, Carlo Maria Petrangeli, Corrado Balacco GabrieliAbstract:Purpose: To investigate the 24 h blood-pressure (BP) pattern in subjects who were found to show some incipient signs of hypertensive retinopathy but had been diagnosed as normotensives by means of casual Sphygmomanometry. Methods: Non-invasive ambulatory BP monitoring was performed in 25 caucasian subjects (16 M, 9 F; mean age 46 ± 16 years) showing this type of retinal problem. A comparable number of controlled normotensive Caucasian subjects (15 M, 10 F; mean age: 48 ± 15 years) without funduscopic signs of hypertensive retinopathy were investigated as a reference group. A series of BP tests over time was analysed by means of conventional biometry and chronobiological methods. Results: The biometric estimates suggest that the investigated subjects with incipient hypertensive retinopathy, although characterized by BP values below 140/90 mmHg, show a significantly higher daily systolic BP. The increase, however, is within WHO reference limits and is not associated with the abolition of the circadian BP rhythm. Conclusions: The results suggest that the initial signs of hypertensive retinopathy may appear before BP elevation above WHO reference limits occurs. Because of this, it can be assumed that there is such a condition as 'minimal-change hypertensive retinopathy' associated with a haemodynamic picture of 'arterial pre-hypertension'.
