Background: Short-term blood pressure (BP) variability (BPV) is associated with increased cardiovascular risk in hemodialysis. Patients with intradialytic hypertension have high risk of adverse outcomes. Whether BPV is increased in these patients is not clear. The purpose of this study was to compare short-term BPV in patients with and without intradialytic hypertension. Methods: Forty-one patients with and 82 patients without intradialytic hypertension (intradialytic SBP rise ≥10 mm Hg to > 150 mm Hg) matched in a 1: 2 ratio for age, sex, and hemodialysis vintage were included. All subjects underwent 48-h ambulatory BP monitoring during a regular hemodialysis and the subsequent interdialytic interval. Brachial and aortic BPV were calculated with validated formulas and compared between the 2 groups during the 48-h and the 44-h periods and during the 2 daytime and nighttime periods respectively. Results: During 48-h or 44-h periods and daytime or nighttime, brachial SBP/DBP and aortic SBP/DBP were significantly higher in cases than in controls. All brachial SBP/DBP BPV indexes [SD, weighted SD (wSD), coefficient-of-variation (CV) and average-real-variability (ARV)] were not significantly different between groups during the 48- or 44-h periods (48-h: SBP-ARV 11.59 ± 3.05 vs. 11.70 ± 2.68, p = 0.844, DBP-ARV: 8.60 ± 1.90 vs. 8.90 ± 1.63, p = 0.357). Analysis stratified by day or night between days 1 and 2 revealed, in general, similar results. No significant differences in dipping pattern were observed between groups. Analysis of aortic BPV had similar findings. Conclusions: BPV is similar between those with and without intradialytic hypertension. However, those with intradialytic hypertension have a sustained increase in systolic and diastolic BP during the entire interdialytic interval.

The prognostic relevance of short-term blood pressure (BP) variability in hypertension is not clearly established. We aimed to evaluate the association of short-term BP variability, assessed through ambulatory BP monitoring, with total and cardiovascular mortality in a large cohort of patients with hypertension. We selected 63 910 subjects from the Spanish ABPM Registry from 2004 to 2014, with a median follow-up of 4.7 years. Systolic and diastolic BP SD from 24 hours, daytime, and nighttime, weighted SD (mean of daytime and nighttime SD weighted for period duration), average real variability (mean of differences between consecutive readings), variation independent of the mean, and BP variability ratio (ratio between systolic and diastolic 24-hour SD) were calculated through 24-hour ambulatory BP monitoring performed at baseline. Association with total and cardiovascular mortality (obtained through death certificates) were assessed by Cox regression models adjusted for clinical confounders and BP. Patients who died during follow-up had higher values of BP variability compared with those remaining alive. In fully adjusted models, daytime, nighttime, and weighted SD, systolic and diastolic, as well as diastolic average real variability, were all significantly associated with total and cardiovascular mortality. Hazard ratios for 1 SD increase ranged from 1.05 to 1.09 for total mortality and from 1.07 to 1.12 for cardiovascular mortality. A nighttime systolic SD ≥12 mm Hg was independently associated with total (hazard ratio: 1.13 [95% CI, 1.06–1.21]) and cardiovascular mortality (hazard ratio: 1.21 [95% CI, 1.09–1.36]). We conclude that short-term BP variability is independently associated with total and cardiovascular mortality in patients with hypertension.

Abstract Arterial blood pressure (BP) is a continuous variable, with a physiology characterized by significant variability stemming from the complex interaction among haemodynamic factors, neuronal reflexes, as well as hormonal, behavioural, and environmental stimuli. The homoeostatic response accounts for the physiologic variability in BP in normotensive individuals, which is more evident in hypertensive patients. Blood pressure variability is a complex phenomenon, which could be classified in various types: very short term (beat to beat), short term (during 24 h), mid-term (day by day), long term (<5 years), and very long term (>5 years). Accurate measurement of BP variability represents a complex and often controversial endeavour, despite several methodological approaches are available. Albeit a prognostic significance has been demonstrated for some indicators of BP variability, the clinical significance of this measurement is still uncertain. In fact, none of the indicators presently available for BP variability, including early morning BP rise, substantially affects, and redefines, the cardiovascular risk of the hypertensive patient, over and beyond the mere BP values. Accordingly, in defining the cardiovascular risk, the focus should be on the absolute BP values, which remain the most relevant risk factor, and the one more susceptible to modification with both non-pharmacologic and pharmacologic treatment.

Data on short-term blood pressure variability (BPV), which is a well-established cardiovascular prognostic tool, in pheochromocytoma and paraganglioma (PPGL) patients is still lack and conflicting. We retrospectively evaluated 23 PPGL patients referred to our unit from 2010 to 2019 to analyze 24 h ambulatory blood pressure monitoring (24-h ABPM)-derived markers of short-term BPV, before and after surgical treatment. PPGL diagnosis was assessed according to guidelines and confirmed by histologic examination. The 24-h ABPM-derived markers of short-term BPV included: circadian pressure rhythm; standard deviation (SD) and weighted SD (wSD) of 24-h, daytime, and night-time systolic and diastolic blood pressure (BP); average real variability (ARV) of 24-h, daytime, and night-time systolic and diastolic BP. 7 males and 16 females of 53 ± 18 years old were evaluated. After surgical resection of PPGL we found a significant decrease in 24-h systolic BP ARV (8.8 ± 1.6 vs. 7.6 ± 1.3 mmHg, p < 0.001), in 24-h diastolic BP ARV (7.5 ± 1.6 vs. 6.9 ± 1.4 mmHg, p = 0.031), and in wSD of 24-h diastolic BP (9.7 ± 2.0 vs 8.8 ± 2.1 mmHg, p = 0.050) comparing to baseline measurements. Moreover, baseline 24-h urinary metanephrines significantly correlated with wSD of both 24-h systolic and diastolic BP. Our study highlights as PPGL patients, after proper treatment, show a significant decrease in some short-term BPV markers, which might represent a further cardiovascular risk factor.

Sleep apnoea is associated with increased cardiovascular risk. Sleep apnoea is common after stroke and associated with increased blood pressure variability as described by Turkington and co-workers in this issue of Clinical Science. Both sleep apnoea and blood pressure variability confer a poor prognosis after stroke and are potentially treatable. Many studies of CPAP (continuous positive airway pressure) demonstrate decreases in cardiovascular risk markers in other patient groups. Although difficult to apply in these patients in the short term, CPAP has some potential benefits in medium-term rehabilitation and secondary prevention following stroke, which warrants further study.

Objective. The aim of this study is to define the normal range for average real variability (ARV) and to establish whether it can be considered as an additional cardiovascular risk factor.Methods. In this observational study, 110 treated hypertensive patients were included and admitted for antihypertensive treatment adjustment. Circadian blood pressure was recorded with validated devices. Blood pressure variability (BPV) was assessed according to the ARV definition. Based on their variability, patients were classified into low, medium, and high variability groups using the fuzzyc-means algorithm. To assess cardiovascular risk, blood samples were collected. Characteristics of the groups were compared by ANOVA tests.Results. Low variability was defined as ARV below 9.8 mmHg (32 patients), medium as 9.8–12.8 mmHg (48 patients), and high variability above 12.8 mmHg (30 patients). Mean systolic blood pressure was 131.2 ± 16.7, 135.0 ± 12.1, and 141.5 ± 11.4 mmHg in the low, medium, and high variability groups, respectively (p=0.0113). Glomerular filtration rate was 78.6 ± 29.3, 74.8 ± 26.4, and62.7±23.2 mL/min/1.73 m2in the low, medium, and high variability groups, respectively (p=0.0261).Conclusion. Increased values of average real variability represent an additional cardiovascular risk factor. Therefore, reducing BP variability might be as important as achieving optimal BP levels, but there is need for further studies to define a widely acceptable threshold value.

Abstract Objective Our work aimed to investigate the association between vigorous physical activity and visit-to-visit systolic blood pressure variability (BPV). Methods We conducted a post hoc analysis of SPRINT (Systolic Blood Pressure Intervention Trial), a well-characterized cohort of participants randomized to intensive (&lt;120 mmHg) or standard (&lt;140 mmHg) SBP targets. We assessed whether patients with hypertension who habitually engage in vigorous physical activity would have lower visit-to-visit systolic BPV compared with those who do not engage in vigorous physical activity. Visit-to-visit systolic BPV was calculated by standard deviation (SD), average real variability (ARV), and standard deviation independent of the mean (SDIM) using measurements taken during the 1-, 2-, 3-, 6-, 9- and 12-month study visits. A medical history questionnaire assessed vigorous physical activity, which was divided into three categories according to the frequency of vigorous physical activity. Results A total of 7571 participants were eligible for analysis (34.8% female, mean age 67.9±9.3 years). During a follow-up of 1-year, vigorous physical activity could significantly reduce SD, ARV, and SDIM across increasing frequency of vigorous physical activity. There were negative linear trends between frequency of vigorous physical activity and visit-to-visit systolic BPV. Conclusions Long-term engagement in vigorous physical activity was associated with lower visit-to-visit systolic BPV.
