“…27 Several studies did not find any correlation between target organ damage and BP variability assessed with intra-arterial 3 and patient-activated 2 or fully automatic 4,28,29 noninvasive monitoring. However, the small sample size 3,4,28,29 or the low number of ambulatory BP readings 2 do not allow for drawing definitive conclusions from these studies. Interestingly, Schmieder et al 30 found that BP at work and during sleep, but not its rise elicited by mental or physical stress, was a determinant of LV hypertrophy.…”

Blood pressure (BP) variability could induce detrimental effects on left ventricular (LV) structure in hypertension. We investigated the association between short-term BP variability, assessed with 24-h noninvasive ambulatory BP monitoring, and LV mass at echocardiography in 1822 untreated subjects (953 men, 869 women) with essential hypertension (EH). The standard deviation (SD) of daytime and night-time systolic BP (SBP, r ‫؍‬ 0.13/0.10; both P < .001), but not of diastolic BP, showed a weak correlation with LV mass. Because the SD of daytime SBP showed a direct association with average 24-h SBP (r ‫؍‬ 0.27), subjects were ranked into quartiles of the distribution of 24-h SBP. For each quartile, the subjects with SD of daytime (and night-time) SBP below or above the median were classified at low or high BP variability. In both genders, subjects with high daytime SBP variability were older than those at low variability (both P < .01). Within each quartile, LV mass did not differ between the groups at low v those at high SBP variability. Overall, age-adjusted LV mass index was 115 and 115 g/m 2 in men at low and high daytime SBP variability (P ‫؍‬ .84), and 116 and 114 g/m 2 in men at low and high nighttime SBP variability (P ‫؍‬ .31). The corresponding values in women were 98 and 99 g/m 2 (P ‫؍‬ .53) and 98 and 99 g/m 2 (P ‫؍‬ .64). In conclusion, when the effects of age, gender, and average 24-h BP are taken into account, short-term BP variability assessed with noninvasive monitoring is unrelated to LV mass in subjects with EH.

“…However, there are other studies where the cited association was not found [10][11][12] or was lost in the presence of other well-known risk factors [13,14]. An explanation for these apparently contradictory results may be the selection of the index [standard deviation (SD)] used for quantifying variability [15][16][17].…”

“…Although the precise quantification of short‐term BPV requires beat‐to‐beat BP recording, its assessment is also possible, even if less accurately, through the use of intermittent noninvasive 24‐hour ambulatory BP monitoring (ABPM). However, studies in which short‐term BPV was estimated by ABPM yielded conflicting results …”

The authors aimed to analyze the relationship between subclinical renal damage, defined as the presence of microalbuminuria or an estimated glomerular filtration rate (eGFR) between 30 mL/min/1.73 m 2 and 60 mL/min/ 1.73 m 2 and short-term blood pressure (BP) variability, assessed as average real variability (ARV), weighted standard deviation (SD) of 24-hour BP, and SD of daytime and nighttime BP. A total of 328 hypertensive patients underwent 24-hour ambulatory BP monitoring, 24-hour albumin excretion rate determination, and eGFR calculation using the Chronic Kidney Disease Epidemiology Collaboration equation. ARV of 24-hour systolic BP (SBP) was significantly higher in patients with subclinical renal damage (P=.001). This association held (P=.04) after adjustment for potential confounders. In patients with microalbuminuria, ARV of 24-hour SBP, weighted SD of 24-hour SBP, and SD of daytime SBP were also independently and inversely related to eGFR. These results seem to suggest that in essential hypertension, short-term BP variability is independently associated with early renal abnormalities. J Clin Hypertens (Greenwich). 2015;17:473-480. ª 2015 Wiley Periodicals, Inc.Since the pioneering observations of Stephen Hales during the 18th century it has been recognized that blood pressure (BP) is not a constant parameter; rather, it shows marked spontaneous oscillations over shortterm (minutes to hours) and long-term (days to months) periods. Far from being a "background noise" that hindered assessment of "true BP," short-term BP variability (BPV) seems to be relevant to the pathophysiology of target organ damage and to the incidence of clinical events, as suggested by studies performed in humans by invasive continuous 24-hour BP measurements 1,2 and as clearly shown by investigations conducted in sinoaortic-denervated rats.3-6 Although the precise quantification of short-term BPV requires beatto-beat BP recording, 7 its assessment is also possible, even if less accurately, through the use of intermittent noninvasive 24-hour ambulatory BP monitoring (ABPM). However, studies in which short-term BPV was estimated by ABPM yielded conflicting results. 8-32Short-term BP variability has been usually estimated by 24-hour, daytime, or nighttime standard deviation (SD) of average BP. However, the limitations of the SD as a measure of short-term BPV have stimulated the search of more refined BPV estimates. 6,7,10,13,20,21 One of these is the average real variability (ARV) of 24-hour BP, ie, the average of the absolute differences of consecutive measurements. 20 This statistical parameter is sensitive to the individual BP measurement order and less sensitive to low sampling frequency of ABPM. 21Some studies suggest that ARV better predicts cardiovascular (CV) risk in comparison to the traditional SD. 20,22,23 Another new index of short-term BPV is the "weighted" SD of the 24-hour mean value, ie, the average SD of daytime and nighttime BP, each weighted for the duration of the day and night periods, respectively. This in order ...
