“…Unfortunately, this hypothesis cannot be tested, as this accurate diagnostic information is not available for the study population. Nevertheless, in a population-based cohort and a patient-based cohort, it has been shown that there was no association between short-term blood pressure variability and subclinical target organ damage [27, 28]. …”

BackgroundPrecise blood pressure (BP) measurements are central for the diagnosis of hypertension in clinical and epidemiological studies. The purpose of this study was to quantify the variability in BP associated with arm side, body position, and successive measurements in the setting of a population-based observational study. Additionally, we aimed to evaluate the influence of different measurement conditions on prevalence of hypertension.MethodsThe sample included 967 men and 812 women aged 45 to 83 years at baseline. BP was measured according to a standardized protocol with oscillometric devices including three sitting measurements at left arm, one simultaneous supine measurement at both arms, and four supine measurements at the arm with the higher BP. Hypertension was defined as systolic BP (SBP) ≥140 mmHg and/or diastolic BP (DBP) ≥90 mmHg. Variability in SBP and DBP were analysed with sex-stratified linear covariance pattern models.ResultsWe found that overall, no mean BP differences were measured according to arm-side, but substantial higher DBP and for men also higher SBP was observed in sitting than in supine position and there was a clear BP decline by consecutive measurement. Accordingly, the prevalence of hypertension depends strongly on the number and scheme of BP measurements taken to calculate the index values.ConclusionsThus, BP measurements should only be compared between studies applying equal measurement conditions and index calculation. Moreover, the first BP measurement should not be used to define hypertension since it overestimates BP. The mean of second and third measurement offers the advantage of better reproducibility over single measurements.Electronic supplementary materialThe online version of this article (doi:10.1186/s12872-017-0468-7) contains supplementary material, which is available to authorized users.

Introduction-Purpose: Pulsed pressure is recognized as an important predictor of cardiovascular risk. The purpose of this study was to identify a possible association between high ambulatory pulsed pressure and left ventricular geometry change in African black people. Material and methods: We conducted a bicentric, retrospective descriptive and analytical study that took place from 2010 to 2015 at the Abidjan Heart Institute and the Polyclinic Sainte Anne Marie in Abidjan. The people were selected from MAPA's archive files. Those aged 18 years and over were included, all of whom had valid echocardiography and MAPA. The analyzed parameters concerned epidemiological data with age, gender and body surface area. The clinical data analyzed included systolic, diastolic, mean and 24-hours pulsed pressures. On the echocardiographic parameters, it was the evaluation of the ventricular mass indexed to the body surface. Results: A total of 177 patients records were selected. The mean age of the patients was 56.32 ± 10.51 years. There was a male predominance with a sex ratio of 1.15. The main cardiovascular risk factors found outside high blood pressure were dyslipidemia (06.87%) and obesity (13.7%). In clinical terms, hypertension was found in 75% of cases (n = 133) versus 25% (n = 44) of normotensive patients. These blood pressure profiles allowed us to classify our study population into two groups: hypertensives people and normotensives people. The hypertensives people had significantly higher mean pulsed pressure levels than the normotensives people. All normotensive patients had normal pulsed pressure. In the hypertensive population, the prevalence of high pulsed pressure was 31% (n = 41) versus 69% (n = 92

“…Accumulating evidence has also shown that BPV observed during 24 h ABPM was also associated with an increased risk of target organ damage and early atherosclerosis in a manner which was independent of mean BP levels. 5 , 6 Several general population-based studies have reported that measures of 24 h BPV could serve as an independent predictor for CV events and all-cause mortality. 7 , 8 More recently, an increasing body of evidence has shown that increased BPV can predict CV events and all-cause mortality in patients with CKD.…”

PurposeIncreased variability in blood pressure (BP) is known to be closely associated with the development, progression and severity of renal damage in patients with chronic kidney disease. However, little is known about the association of BP variability (BPV) with the decline of renal function in elderly hypertensive patients with well-controlled BP. We, therefore, aimed to investigate the association between BPV and glomerular filtration rate in hypertensive elderly (age >60 years) and very elderly (age >80 years) male patients with BP controlled within the normal range by antihypertensive therapy.Patients and methodsThis study involved 484 hospitalized elderly male hypertensive patients with BP controlled within the normal range by antihypertensive therapy. BPV was defined as the SD from mean BP over a 24 h period. Renal function was estimated by estimated glomerular filtration rate (eGFR) which was calculated by the Chinese modified Modification of Diet in Renal Disease Equation. Participants were divided into three groups according to their eGFR data. Multivariate linear regression was then used to analyze the correlation between eGFR and BPV.ResultsThe 24 h systolic BP (SBP) variability increased as eGFR decreased. There was no significant difference in 24 h SBP variability when compared between elderly and very elderly hypertensive patients. Multivariate linear regression analysis showed that SBP variability demonstrated a negative linear relationship with eGFR (P<0.05) after adjustment for potential confounding factors.ConclusionAmong the parameters of 24 h ambulatory BP monitoring, 24 h SBP variability is the only independent risk factor for a decline in renal function in elderly and very elderly male hypertensive patients with well-controlled BP.
