Introduction: Mean daytime ambulatory blood pressure (ABP) values are considered to be lower than conventional BP (CBP) values, but data on this relation among younger individuals <50 years are scarce. To address this issue, we performed a collaborative analysis in a large group of participants representing a wide age range. Methods: CBP and 24-hour ABP were measured in 9550 individuals not taking BP lowering treatment from 13 population based cohorts. We compared the individual differences between daytime ABP and CBP according to 10-year age categories. Age-specific prevalences of white-coat hypertension and masked hypertension were calculated based on guideline-recommended thresholds. Results: Among individuals aged 18-30, 30-40 and 40-50 years, mean daytime systolic and diastolic ABP were significantly higher than the corresponding CBP (6.0, 5.2 and 4.7 mmHg for systolic BP; 2.5, 2.7 and 1.7 mmHg for diastolic BP, all p<0.0001) (Figure). Systolic and diastolic BP indices were similar in participants aged 50-60 years (p=0.20 and 0.11, respectively). In individuals aged 60-70 and ≥70 years, CBP was significantly higher than daytime ABP (5.0 and 13.0 mmHg for systolic BP; 2.0 and 4.2 mmHg for diastolic BP, all p<0.0001) (Figure). Accordingly, the prevalence of white coat hypertension exponentially increased from 2.2% to 19.5% from those aged 18-30 years to those aged ≥70 years, with some variation between men and women (prevalence 8.0% versus 6.1%, p=0.0003). Masked hypertension was more prevalent among men (21.1% versus 11.4%, p<0.0001). The age-specific prevalence of masked hypertension was 18.2%, 27.3%, 27.8%, 20.1% 13.6% and 10.2% in men, and 9.0%, 9.9%, 12.2%, 11.9%, 14.7% and 12.1% in women. Conclusions: In this large collaborative analysis we found that the relation between daytime ABP and CBP strongly varies by age. These findings may have important implications for the diagnosis of hypertension and its subtypes in clinical practice.

Background: Few studies have compared accurately measured office, self-measured home, and ambulatory blood pressure (BP) for asymptomatic intracranial artery stenosis (ICAS). Relationship of day-by-day or short-term variability in BP to asymptomatic ICAS remains unclear. Objectives: To examine the association of office, home (mean value and day-by-day variability), and ambulatory BP indices (24-hour/daytime/nighttime mean values, short-term variability, nocturnal decline, and morning pressor surge) with asymptomatic ICAS. Methods: Data on office and 7-day home BP and magnetic resonance angiography to assess ICAS were obtained in 677 men (mean age, 70.0 years) from a population-based cohort. Among them, 468 underwent 24-hour ambulatory BP monitoring. Mild- or severe-ICAS was defined as 1-49% or ≥50% stenosis, respectively, and any-ICAS as either mild or severe-ICAS. Results: We observed mild- and severe-ICAS in 153 (22.6%) and 36 (5.3%) participants, respectively. In multivariable Poisson regression with robust error variance, higher systolic BP at office, home, or ambulatory BP monitoring was associated with the presence of any- or severe-ICAS. The associations with ICAS were comparable between office, home, and ambulatory systolic BP (all heterogeneity Ps >0.1). Independent of mean systolic BP, greater nocturnal decline or morning pressor surge in systolic BP was associated with higher burden of any- or severe-ICAS. Conclusion: The magnitude of association of BP accurately measured at office for asymptomatic ICAS was comparable with that of BP at home or ambulatory BP monitoring. Circadian BP variation based on ambulatory BP monitoring may be considered when assessing ICAS in apparently healthy individuals.

Several ambulatory blood pressure monitoring (ABPM) phenotypes including masked hypertension are associated with an increased risk for cardiovascular disease (CVD). Diabetes is associated with CVD risk as well as a higher prevalence of hypertension. However, little is known about whether ABPM phenotypes differ between individuals with versus without diabetes. We evaluated the association between diabetes and ABPM phenotypes including clinic hypertension, awake hypertension, sustained hypertension, nocturnal hypertension, non-dipping pattern, white coat hypertension, and masked hypertension in the Jackson Heart Study (JHS). Baseline data collection included two clinic blood pressure measurements using standardized protocols. ABPM measurements were taken in the 24 hours following the baseline visit. Diabetes was defined as fasting glucose ≥126 mg/dL, hemoglobin A1c ≥6.5%, or use of diabetes medications. Of the 1,032 JHS participants with valid ABPM data (67.7% female, mean age 59.2 years), 253 (24.5%) had diabetes. The prevalence of clinic hypertension was similar for participants with and without diabetes (Table 1). After multivariable adjustment, diabetes was associated with an increased prevalence ratio of awake, sustained, and masked hypertension and a lower prevalence ratio of white coat hypertension compared with individuals without diabetes. In summary, there was an increased prevalence of adverse blood pressure phenotypes among individuals with versus those without diabetes that was not captured in the clinic setting alone. The role of ABPM for identifying high risk individuals with diabetes should be further investigated.

Abstract Background Population-specific consensus documents recommend that the diagnosis of hypertension in haemodialysis patients be based on 48-h ambulatory blood pressure (ABP) monitoring. However, until now there is just one study in the USA on the prevalence of hypertension in haemodialysis patients by 44-h recordings. Since there is a knowledge gap on the problem in European countries, we reassessed the problem in the European Cardiovascular and Renal Medicine working group Registry of the European Renal Association-European Dialysis and Transplant Association. Methods A total of 396 haemodialysis patients underwent 48-h ABP monitoring during a regular haemodialysis session and the subsequent interdialytic interval. Hypertension was defined as (i) pre-haemodialysis blood pressure (BP) ≥140/90 mmHg or use of antihypertensive agents and (ii) ABP ≥130/80 mmHg or use of antihypertensive agents. Results The prevalence of hypertension by 48-h ABP monitoring was very high (84.3%) and close to that by pre-haemodialysis BP (89.4%) but the agreement of the two techniques was not of the same magnitude (κ statistics = 0.648; P &lt;0.001). In all, 290 participants were receiving antihypertensive treatment. In all, 9.1% of haemodialysis patients were categorized as normotensives, 12.6% had controlled hypertension confirmed by the two BP techniques, while 46.0% had uncontrolled hypertension with both techniques. The prevalence of white coat hypertension was 18.2% and that of masked hypertension 14.1%. Of note, hypertension was confined only to night-time in 22.2% of patients while just 1% of patients had only daytime hypertension. Pre-dialysis BP ≥140/90 mmHg had 76% sensitivity and 54% specificity for the diagnosis of BP ≥130/80 mmHg by 48-h ABP monitoring. Conclusions The prevalence of hypertension in haemodialysis patients assessed by 48-h ABP monitoring is very high. Pre-haemodialysis BP poorly reflects the 48 h-ABP burden. About a third of the haemodialysis population has white coat or masked hypertension. These findings add weight to consensus documents supporting the use of ABP monitoring for proper hypertension diagnosis and treatment in this population.
