Management of nocturnal hypertension: An expert consensus document from Chinese Hypertension League. J Clin Hypertens (Greenwich) 2024; 26:71-83. [PMID: 38126623 PMCID: PMC10795100 DOI: 10.1111/jch.14757] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 10/20/2023] [Accepted: 11/20/2023] [Indexed: 12/23/2023]
Abstract
Nocturnal hypertension is highly prevalent among Chinese and Asian populations, which is mainly attributed to high salt intake and high salt sensitivity. Nocturnal hypertension increases the risk of cardiovascular and all-cause mortality, independent of daytime blood pressure (BP). However, it can usually be detected by 24-h ambulatory BP monitoring, rather than routine office or home BP measurement, thus is often underdiagnosed in clinical practice. Currently, no specific guidance is available for the management of nocturnal hypertension in China or worldwide. Experts from the Chinese Hypertension League summarized the epidemiologic and pathophysiologic characteristics and clinical phenotype of nocturnal hypertension and provided consensus recommendations on optimal management of nocturnal hypertension, with the goal of maximally reducing the cardiovascular disease risks. In this consensus document, 24-h ABPM is recommended for screening and diagnosis of nocturnal hypertension, especially in the elderly, patients with diabetes, chronic kidney diseases, obstructive sleep apnea and other conditions prone to high nocturnal BP. Lifestyle modifications including salt intake restriction, exercise, weight loss, sleep improvement, and mental stress relief are recommended. Long-acting antihypertensive medications are preferred for nocturnal and 24-h BP control. Some newly developed agents, renal denervation, and other device-based therapy on nocturnal BP reduction are evaluated.

High plasma aldosterone concentration is associated with worse 24-h ambulatory blood pressure profile in patients with primary aldosteronism. Hypertens Res 2023; 46:1995-2004. [PMID: 37253977 DOI: 10.1038/s41440-023-01325-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 04/14/2023] [Accepted: 04/19/2023] [Indexed: 06/01/2023]
Abstract
Patients with primary aldosteronism (PA) have a higher risk of cardiovascular disease (CVD) than essential hypertension due to underlying hyperaldosteronism. However, the association between high plasma aldosterone concentrations (PACs) and diurnal blood pressure (BP) variation has not been fully elucidated. Because abnormal ambulatory blood pressure monitoring (ABPM) profiles are associated with increased CVD risk, we investigated the association between PACs and the ABPM profile in 36 patients with PA diagnosed by confirmatory tests who underwent adrenal venous sampling (AVS). The clinical parameters were measured during hospitalization for AVS. The dietary salt intake of hospitalized patients was controlled at 6 g/day. During AVS, blood samples were collected from the inferior vena cava before and 1 h after adrenocorticotropic hormone (ACTH) stimulation to measure the PACs. The post-stimulation PAC had a significant negative correlation with nocturnal BP dipping rates (R = -0.387, p = 0.020), whereas pre-stimulation PAC did not (R = -0.217, p = 0.204). The nocturnal BP dipping rates were significantly lower in the high PAC group (PAC higher than the median) than low PAC group (PAC lower than the median) (p = 0.009). Multiple regression analysis revealed that high PAC was an independent factor contributing to low nocturnal BP dipping rates (β = -0.316, p = 0.038). In conclusion, in patients with PA, hyperaldosteronism is associated with nocturnal hypertension, which is an important risk factor for CVD. Additionally, ACTH stimulation may improve the sensitivity of PACs as a clinical indicator of nocturnal hypertension.

Abstract
Midlife hypertension increases risk for dementia. Around one third of adults have diagnosed hypertension; however, many adults are undiagnosed, or remain hypertensive despite diagnosis or treatment. Since blood pressure (BP) follows a circadian rhythm, ambulatory BP monitoring allows for the assessment of BP over a 24-hour period and provides an important tool for improving the diagnosis and management of hypertension. The measurement of 24-hour BP profiles, especially nocturnal BP, demonstrate better predictive ability for cardiovascular disease and mortality than office measurement. However, few studies have examined 24-hour BP profiles with respect to dementia risk. This is an important topic since improvements in BP management could facilitate the primary prevention of vascular cognitive impairment and dementia. Therefore, this review discusses the evidence linking BP to dementia, with a focus on whether the implementation of 24-hour BP measurements can improve risk prediction and prevention strategies. Pathways linking nocturnal BP to dementia are also discussed as are risk reduction strategies. Overall, limited research suggests an association between 24-hour BP elevation and poorer cognition, cerebral small vessel disease, and dementia. However, most studies were cross-sectional. Further evidence is needed to substantiate 24-hour BP profiles, over and above office BP, as predictors of vascular cognitive impairment and incident dementia.

Abstract
Circadian blood pressure (BP) rhythm is important for the maintenance of healthy daily life, and its disruption is associated with poor outcomes. Cardiovascular autonomic failure is often observed in older populations but has a greater impact on neurodegenerative disorders such as α-synucleinopathies. These BP abnormalities include orthostatic hypotension (OH), supine hypertension (SH), and a loss of nocturnal BP fall. OH not only causes falls or syncope but is also related to cognitive impairment in α-synucleinopathies. For example, OH doubles or triples the risk for the development of cognitive impairment in Parkinson's disease (PD). The diffuse central and peripheral neuropathology of α-synuclein may contribute to both OH and cognitive impairment. Moreover, repeated cerebral hypoperfusion in OH is thought to be related to cerebrovascular and neuronal damage, which may cause cognitive impairment. SH, which often coexists with OH, is also associated with cognitive impairment through cerebrovascular damage, such as white matter lesions and cerebral microbleeds. The reverse-dipping (riser) pattern on ambulatory BP monitoring is commonly observed in PD (∼56%), regardless of disease duration and severity. It is also related to cognitive impairment and more pronounced when coexisting with OH. These abnormal circadian BP profiles may be synergistically associated with cognitive impairment and poor outcomes in α-synucleinopathies. Although evidence for aggressive control of BP dysregulation improving cognitive impairment and outcomes is limited, regular BP monitoring appears to be important for total management of α-synucleinopathies.

Abstract
Background Although blood pressure variability (BPV) has emerged as a novel risk factor for Alzheimer's disease, few studies have examined the effects of night BPV on brain structure and function. This study investigated the association of night BPV with brain atrophy and cognitive function changes. Methods The analysis included 1,398 participants with valid ambulatory blood pressure (BP) monitoring at baseline and both baseline and 4-year follow-up brain magnetic resonance images who were recruited from the Korean Genome and Epidemiology Study. Participants underwent a comprehensive neuropsychological test battery. BPV was derived from ambulatory BP monitoring and calculated as a standard deviation (SD) of 24-h and daytime and nighttime BP. Results During the median follow-up of 4.3 years, increased SD of night systolic or diastolic BP was an indicator of total brain volume reduction, while daytime BPV or night average BP was not associated with total brain volume changes. High SD of night systolic BP was associated with reduced gray matter (GM) volume, independent of average night BP, and use of antihypertensive drugs. It also was associated with a reduction of temporal GM volume, mostly driven by atrophy in the left entorhinal cortex and the right fusiform gyrus. In cognitive performance, high variability of night systolic BP was associated with a decrease in visual delayed recall memory and verbal fluency for the category. Conclusion Increased night BPV, rather than night mean BP, was associated with reduced brain volume and cognitive decline. High night BPV could be an independent predictor for rapid brain aging in a middle-aged population.

The Key Role of Ambulatory Blood Pressure Monitoring in the Detection of Masked Hypertension and Other Phenomena in Frail Geriatric Patients. Medicina (B Aires) 2021; 57:medicina57111221. [PMID: 34833439 PMCID: PMC8622895 DOI: 10.3390/medicina57111221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 11/01/2021] [Accepted: 11/05/2021] [Indexed: 11/24/2022] Open
Abstract
Background and Objectives: This study aims to determine prevalence of masked uncontrolled hypertension (MUH) in frail geriatric patients with arterial hypertension and thus show the role of ambulatory blood pressure monitoring (ABPM) since hypertension occurs in more than 80% of people 60+ years and cardiovascular diseases are the main cause of death worldwide. Despite modern pharmacotherapy, use of combination therapy and normal office blood pressure (BP), patients’ prognoses might worsen due to inadequate therapy (never-detected MUH). Materials and Methods: 118 frail geriatric patients (84.2 ± 4.4 years) treated for arterial hypertension with office BP < 140/90 mmHg participated in the study. 24-h ABPM and clinical examination were performed. Results: Although patients were normotensive in the office, 24-h measurements showed that BP values in 72% of hypertensives were not in the target range: MUH was identified in 47 (40%) patients during 24 h, in 48 (41%) patients during daytime and nocturnal hypertension in 60 (51%) patients. Conclusions: ABPM is essential for frail geriatric patients due to high prevalence of MUH, which cannot be detected based on office BP measurements. ABPM also helps to detect exaggerated morning surge, isolated systolic hypertension, dipping/non-dipping, and set and properly manage adequate treatment, which reduces incidence of cardiovascular events and contributes to decreasing the financial burden of society.

Abstract
Hypertension and heart failure are common conditions in older people. Comorbidity, together with aging, is commonly associated with frailty, which is a cause of a worse prognosis, more hospitalizations, increased dependency, and mortality. Despite being increasingly common conditions, data on the prevalence and influence of frailty in hypertensive older patients with HF are lacking. This may be due to the multidimensional aspects of frailty and the differing tools used to evaluate it. Nevertheless, in clinical practice, it is common to see frail hypertensive patients with HF but the specific characteristics of this group of patients, including multimorbidity and frailty, and the lack of data from registries or randomized clinical trials make the diagnosis and management of these patients more difficult than in those of other ages. This review focuses on what is known and on where future investigations should focus in this common but unclear situation.

Abstract
Hypertension is an important factor affecting the health of older adults. Antihypertensives can reduce stroke, cardiovascular events, and mortality in older hypertensive patients. Blood pressure management is difficult in older adults since geriatric syndromes such as frailty and comorbidities often coexist with hypertension. Recent guidelines propose taking functional status into account when targeting blood pressure in older people. Therefore, a better understanding and control of frailty risk factors could improve the prognosis of older adults with hypertension. However, there are relatively few studies on hypertension and frailty in older adults, especially studies focused on antihypertensive treatment. The goals, target values, and choice of antihypertensive treatment for frail older adults are still disputed. We reviewed the recent literature focusing on frailty and hypertension in older adults and propose a management process for screening and assessing frailty and hypertension before the use of antihypertensives. The process can support older adults with lifestyle interventions and frailty management and help them begin taking a single antihypertensive medication.

Abstract
Accurate office blood pressure measurement remains crucial in the diagnosis and management of hypertension worldwide, including Latin America (LA). Office blood pressure (OBP) measurement is still the leading technique in LA for screening and diagnosis of hypertension, monitoring of treatment, and long-term follow-up. Despite this, due to the increasing awareness of the limitations affecting OBP and to the accumulating evidence on the importance of ambulatory BP monitoring (ABPM), as a complement of OBP in the clinical approach to the hypertensive patient, a progressively greater attention has been paid worldwide to the information on daytime and nighttime BP patterns offered by 24-h ABPM in the diagnostic, prognostic, and therapeutic management of hypertension. In LA countries, most of the Scientific Societies of Hypertension and/or Cardiology have issued guidelines for hypertension care, and most of them include a special section on ABPM. Also, full guidelines on ABPM are available. However, despite the available evidence on the advantages of ABPM for the diagnosis and management of hypertension in LA, availability of ABPM is often restricted to cities with large population, and access to this technology by lower-income patients is sometimes limited by its excessive cost. The authors hope that this document might stimulate health authorities in each LA Country, as well as in other countries in the world, to regulate ABPM access and to widen the range of patients able to access the benefits of this technique.

Abstract
BACKGROUND This cross-sectional study was designed to examine the association between home blood pressure and cognitive impairment in elderly patients with type 2 diabetes. METHODS Home blood pressure was measured in the morning and evening for 14 consecutive days in 749 patients with type 2 diabetes. A total of 231 patients were included in the study population. Cognitive function was evaluated using the Mini-Cog test, which is used as a screening for cognitive impairment in elderly patients. We performed a logistic regression analysis and measured the area under the receiver operating characteristic curve and estimated home blood pressure as a marker of cognitive impairment. RESULTS The adjusted odds ratio (95% confidence interval) of evening systolic blood pressure for cognitive impairment was 1.24 (1.02-1.53). Evening systolic blood pressure showed the highest area under the receiver operating characteristic curve for cognitive impairment in both unadjusted and adjusted models. In all subgroup analyses except gender, home blood pressure showed higher area under the receiver operating characteristic curve than clinic blood pressure. CONCLUSION Home blood pressure was associated with cognitive impairment in elderly patients with type 2 diabetes.

OBJECTIVE This study compared the processing speed, static and dynamic balance, functional mobility and fear of falling between individuals with hypertension (HT group) and normotensive individuals (NT group). METHODS One-hundred and twenty-eight individuals were included: NT group (n = 64) and HT group (n = 64). The Choice Stepping Reaction Time Test was used for the evaluation of processing speed, Single Leg Stance test for static balance evaluation, "Y" Balance Test for dynamic balance evaluation, Timed Up and Go test with single and dual tasking for the evaluation of functional mobility and Falls Efficacy Scale for assessing fear of falling. RESULTS The processing speed of the HT group was slower than that of the NT group; the total response time (RsT) in Stepping Reaction Test (SRT) (mean difference [MD] = -0.2, 95% CI = -0.3, 0), and Stroop Test (ST) [ST-A (MD = -0.4, 95% CI = -0.5, -0.2), ST-B (MD = -0.5, 95% CI = -0.7, -0.2) and ST-C (MD = -0.6, 95% CI = -0.8, -0.3). Additionally, the static [single leg stance, eyes open, right side (MD = 12.7, 95% CI = 6.3, 19.0) and left side (MD = 13.6, 95% CI = 7.2, 19.9)] and dynamic balance [Y balance test, composite score, right lower extremity (MD = 8.5, 95% CI = 4.4, 12.5) and left lower extremity (MD = 5.2, 95% CI = 1.5, 8.8) scores of the HT group were lower than those of the NT group. The HT group required a longer time to complete the functional mobility test measured with Timed Up And Go Test during both single task (MD = -0.8, 95% CI = -1.1, -0.4), cognitive dual task (MD = -1.5, 95% CI = -2.4, -0.5) and manual dual task (MD = -0.9, 95% CI = -1.3, -0.4) in comparison to the NT group. Also, the HT group had higher levels of fear of falling (MD = -7.6, 95% CI = -10.9, -4.2). CONCLUSION Hypertensive individuals present slower processing speed, reduced static and dynamic balance, decreased functional mobility and higher fear of falling in comparison to normotensive individuals.

Abstract
According to the established validation protocols, a typical validation study of a blood pressure (BP) monitor includes general population adults with normal or elevated BP. It is recognized, however, that the automated (oscillometric) BP monitors may have different accuracy or uses in some special populations compared with adults in the general population. Thus, an automated BP monitor with proven accuracy in a general population of adults may not be accurate in a special population, and therefore separate validation is needed. Recognized special populations deserving separate validation are those for which there is theoretical, and also clinical evidence, that the accuracy of BP monitors in these groups differs from that in the general population. Young children, pregnant women (including those with preeclampsia), individuals with arm circumference >42 cm, and patients with atrial fibrillation are regarded as special populations. Adolescents, individuals older than 80 years, and patients with end-stage renal disease or diabetes mellitus have also been considered as possible special groups, but there is still inadequate evidence of altered accuracy of BP monitors in these subjects. Validation studies should be performed in special populations and evaluated separately after the BP-measuring device has successfully undergone a validation study in a general population (unless the test device is intended only for a special population). This article discusses issues relating to the measurement of BP and the diagnosis of hypertension in selected special populations, as well as in low-resource settings, where a simplified yet efficient evaluation strategy is necessary.

Abstract
BACKGROUND AND OBJECTIVE Frailty and disability are associated with cardiovascular risk factors, including hypertension, in older people; however, little is known about their association with ambulatory blood pressure (BP). Thus, we assessed the relationship of frailty and disability with ambulatory BP in older adults. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional study of 1047 community-living individuals aged ≥60 years in Spain. MEASUREMENTS BP was determined with validated devices under standardized conditions during 24 hours. Frailty was defined as having 3 or more of the following criteria: weight loss, low grip strength, low energy, slow gait speed, and low physical activity. Disability was assessed with the Lawton-Brodýs questionnaire on instrumental activities of daily living. Associations with systolic BP (SBP) and dipping (nocturnal SBP decline) were modeled and adjusted for sociodemographic variables, body mass index, lifestyles, antihypertensive drug treatment, comorbidities, 24-hour heart rate, and conventional or ambulatory SBP as appropriate. RESULTS Participants' mean age was 71.7 years (50.8% men); 6% were frail and 8.1% had disability. Compared with nonfrail participants, those with frailty had 3.5 mm Hg lower daytime SBP (P = .001), 3.3% less SBP dipping (P = .003), and 3.6 mmHg higher nighttime SBP (P = .016). Compared with participants who are not disabled, those who are disabled had 2.5 mmHg lower daytime SBP (P = .002), 2.5% less SBP dipping (P = .003), and 2.7 mmHg higher nighttime SBP (P = .011). CONCLUSIONS In community-dwelling older adults, frailty and disability were independently associated with lower diurnal SBP, blunted nocturnal decline of SBP, and higher nocturnal SBP. These findings may help explain the higher mortality associated with low clinic SBP in frail older subjects observed in epidemiologic studies.

Abstract
BACKGROUND Whether the association of blood pressure (BP) during sleep (nocturnal BP) with cognition differs by race is unknown. METHODS AND RESULTS Participants in the GENOA (Genetic Epidemiology Network of Arteriopathy) Study underwent ambulatory BP measurements, brain magnetic resonance imaging, and cognitive function testing (the Rey Auditory Verbal Learning Test, the Digit Symbol Substitution Task, and the Trail Making Test Part B) between 2000 and 2007. We examined multivariable linear regression models of the nocturnal BP-cognition association. Among 755 participants (mean age, 63 years; 64% women; 42% self-identified black race; 76% taking antihypertensive medication), mean nocturnal systolic BP (SBP)/diastolic BP was 126/69 mm Hg, daytime SBP/diastolic BP level was 139/82 mm Hg, and mean reduction in SBP from day to night (dipping) was 9%. Among the entire sample, a race interaction was observed in Digit Symbol Substitution Task and Trail Making Test Part B (both P<0.15). Race-stratified analyses showed that a 1-SD increase in nocturnal SBP levels was associated with poorer Digit Symbol Substitution Task and log-transformed Trail Making Test Part B scores (unstandardized regression coefficient [95% confidence interval]: -1.98 [-3.28 to -0.69] and 0.06 [0.004-0.12]; both P<0.05) in black but not white individuals. Additional adjustments for white matter hyperintensity volumes or brain atrophy, measured via brain magnetic resonance imaging, did not change the results. Results were similar when nocturnal SBP dipping was assessed as the exposure, yet daytime SBP levels yielded no association with cognition. CONCLUSIONS Nocturnal SBP measurements may be useful in assessing the potential risk for lower cognitive function in middle-aged and older adults, particularly in black individuals.

Abstract
Out-of-office blood pressure (BP) measured by home BP monitoring, or ambulatory BP monitoring, was demonstrated to be superior to office BP for the prediction of cardiovascular events. The J-HOP study of a nationwide Japanese cohort demonstrated that morning home BP is the best stroke predictor. In the prospective HONEST study of >21 000 hypertensives, on-treatment morning home BP was shown to be a strong predictor both of future coronary artery disease and stroke events. In subjects whose office BP was maintained at ⩾150 mm Hg, there was no increase in cardiovascular events when their morning systolic BP was well-controlled at <125 mm Hg. Since Asians show greater morning BP surges, it is particularly important for Asians to achieve 'perfect 24-hr BP control,' that is, the 24-h BP level, nocturnal BP dipping and BP variability including morning surge. The morning BP surge and the extremes of disrupted circadian rhythm (riser and extreme dipper patterns) are independent risks for stroke in hypertensives. A morning BP-guided approach is thus the first step toward perfect 24-h BP control, followed by the control of nocturnal hypertension. In the resonance hypothesis, the synergistic resonance of BP variability phenotypes would produce an extraordinary large 'dynamic BP surge' that can trigger a cardiovascular event, especially in high-risk patients with systemic hemodynamic atherothrombotic syndrome, a vicious cycle of exaggerated BP variability and vascular disease. In the future, information and communications technology and artificial intelligence technology with the innovation of wearable continuous surge BP monitoring will contribute to 'anticipation medicine' with the goal of zero cardiovascular events.

Abstract
Evidence on the association of nocturnal hypertension (NH) with subclinical cardiac and vascular damage is scanty. The authors performed a meta-analysis to provide comprehensive information on this clinically relevant issue. Full articles providing data on subclinical cardiac and carotid damage as assessed by ultrasonographic methods in patients with NH as compared with patients with nocturnal normotension (NN) were considered. A total of 3657 patients (NH=2083, NN=1574) of both sexes were included in seven studies. Left ventricular mass index was higher in individuals with NH than in those with NN (112±4.7 g/m(2) vs 98±4.8 g/m(2) ; standard mean difference [SMD], 0.54±0.16; confidence interval [CI], 0.23-0.85; P<.01). Similarly, common carotid intima-media thickness was greater in patients with NH than in those with NN (751±34 μm vs 653±14 μm; SMD, 0.44±0.08; CI, 0.29-0.59; P<.01). The present meta-analysis shows an association between NH pattern and increased likelihood of cardiac and carotid structural alterations.

Abstract
OBJECTIVES A reverse dipping pattern, characterized by higher night-time blood pressure (BP) than daytime BP, is associated with the increased risk for cerebrovascular disease, cardiovascular events and all-cause mortality. However, little has known about the association between white matter change (WMC) and reverse dipping pattern, particularly in normotensive adults. We aimed to examine whether WMC is associated with BP dipping patterns as measured with a 24-h ambulatory BP monitoring and whether obstructive sleep apnoea (OSA) is involved in this relationship METHODS : A total of 703 normotensive adults were from an ongoing longitudinal study in a general population. WMC was measured with brain MRI. BP dipping patterns were defined as the ratio of the change in night-time and daytime SBP. OSA was categorized with the apnoea-hypopnea index, as measured with polysomnography. To avoid the influence of hypertensive medications, we only included normotensive adults for the final analysis. To examine the associations between WMC and dipping patterns, we built logistic models. To elucidate the role of OSA, we also conducted both modification and mediation tests. RESULTS Reverse dipping pattern was significantly associated with WMC (odds ratio 1.49, 95% confidence interval 1.02-2.18). Further, OSA modified the association between dipping patterns and WMC (P = 0.0118). No mediation effect of OSA was assessed. CONCLUSION In 703 normotensive adults, the reverse dipping pattern showed a significant association with WMC, after adjusting for covariates. Further, according to the presence of OSA, the association between reverse dipping and WMC was varied.

Abstract
BACKGROUND Nocturnal blood pressure (BP) is associated with risk for cardiovascular events. However, the relationship between nocturnal BP in young adults and cognitive function in midlife remains unclear. METHODS We used data from the ambulatory BP monitoring substudy of the Coronary Artery Risk Development in Young Adults Study, including 224 participants (mean age 30 years, 45% men, 63% African Americans). At the 20-year follow-up, the Stroop test (executive function), Digit Symbol Substitution Test (psychomotor speed), and Rey Auditory Verbal Learning Test (verbal memory) were assessed. RESULTS Baseline mean office, daytime, and nocturnal BP were 109/73, 120/74, and 107/59 mm Hg, respectively. Nocturnal BP dipping, calculated as (nocturnal systolic BP [SBP]--daytime SBP) × 100/daytime SBP, was divided into quartiles (Q1: -39.3% to -16.9%; Q2: -16.8% to -13.2%, Q3 [reference]: -13.1% to -7.8%, and Q4: -7.7% to +56.4%). In multiple regression analyses, the least nocturnal SBP dipping (Q4 vs. reference) and higher nocturnal diastolic BP level were associated with worse Stroop scores, with adjustments for demographic and clinical characteristics, and cumulative exposure to office BP during follow-up (β [standard error]: 0.37 [0.18] and 0.19 [0.07], respectively; all P < 0.05). Digit Symbol Substitution Test and Rey Auditory Verbal Learning Test were not significantly associated with nocturnal SBP dipping or nocturnal SBP/diastolic BP levels. CONCLUSIONS Among healthy young adults, less nocturnal SBP dipping and higher nocturnal diastolic BP levels were associated with lower executive function in midlife, independent of multiple measures of office BP during long-term follow-up.

Abstract
In addition to hypertension, dyslipidemia, atherosclerosis, and diabetes, a sedentary lifestyle plays a pivotal role in cerebro- and cardiovascular disease and progressive cognitive decline, including vascular dementia and Alzheimer's disease. The present study investigated whether controlling the key risks and participating in physical activity have a beneficial impact on these disorders. Elderly volunteers were enrolled in a 3-month program that consisted of structured exercise three times per week. The daily routine, medical treatment, and vital parameters were evaluated and correlated with the subjects' neuropsychiatric status. High blood pressure was found in 40% of the participants, with no significant differences between the sexes. A higher proportion of females (55%) than males (18%) forgot to take their medication during the observation period. Significant negative correlations were found between Mini-Mental State Examination (MMSE) scores and age, lack of a caregiver, and increased pulse rate before or after exercise. These results suggest that the presence of home assistance and subsequent improvement in medication compliance, vital parameter optimization, and regular physical activity may yield better MMSE results and a lower risk for cerebro- and cardiovascular disease.

Methods: One hundred and twenty intracranial trauma patients enrolled in our hospital from February 2011 to July 2013 were selected, including 40 hypertension and 80 non-hypertension cases. They were investigated by MiniMental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) scales, and the clinical data were retrospectively analyzed. Results: Compared with the control group, the MoCA, visuospatial executive function, attention, language, delayed recall, MMSE, orientation and memory scores of the hypertension group were significantly lower. Unconditional Logistic regression analysis showed that age, history of cerebrovascular disease and triglyceride level were the independent risk factors of cognitive function. Conclusion: The blood pressure levels of intracranial trauma patients were associated with cognitive function, with age, history of cerebrovascular disease and triglyceride level as the independent risk factors. Therefore, it is necessary to control blood pressure level to improve prognosis.

Abstract
Ambulatory blood pressure monitoring (ABPM) is being used increasingly in both clinical practice and hypertension research. Although there are many guidelines that emphasize the indications for ABPM, there is no comprehensive guideline dealing with all aspects of the technique. It was agreed at a consensus meeting on ABPM in Milan in 2011 that the 34 attendees should prepare a comprehensive position paper on the scientific evidence for ABPM.This position paper considers the historical background, the advantages and limitations of ABPM, the threshold levels for practice, and the cost-effectiveness of the technique. It examines the need for selecting an appropriate device, the accuracy of devices, the additional information and indices that ABPM devices may provide, and the software requirements.At a practical level, the paper details the requirements for using ABPM in clinical practice, editing considerations, the number of measurements required, and the circumstances, such as obesity and arrhythmias, when particular care needs to be taken when using ABPM.The clinical indications for ABPM, among which white-coat phenomena, masked hypertension, and nocturnal hypertension appear to be prominent, are outlined in detail along with special considerations that apply in certain clinical circumstances, such as childhood, the elderly and pregnancy, and in cardiovascular illness, examples being stroke and chronic renal disease, and the place of home measurement of blood pressure in relation to ABPM is appraised.The role of ABPM in research circumstances, such as pharmacological trials and in the prediction of outcome in epidemiological studies is examined and finally the implementation of ABPM in practice is considered in relation to the issue of reimbursement in different countries, the provision of the technique by primary care practices, hospital clinics and pharmacies, and the growing role of registries of ABPM in many countries.

Abstract
PURPOSE To compare neurovascular coupling in the posterior cerebral artery (PCA) between those with spinal cord injury (SCI) and able bodied (AB) individuals. METHODS A total of seven SCI and seven AB were matched for age and sex. Measures included PCA velocity (PCAv), beat-by-beat blood pressure and end-tidal carbon dioxide. Posterior cerebral cortex activation was achieved by 10 cycles of (1) 30 s eyes closed (pre-stimulation), (2) 30 s reading (stimulation). RESULTS Blood pressure was significantly reduced in those with SCI (SBP: 100 ± 13 mmHg; DBP: 58 ± 13 mmHg) vs. AB (SBP 121 ± 12 mmHg; DBP: 74 ± 9 mmHg) during both pre-stimulation and stimulation, but the relative increase was similar during the stimulation period. Changes in PCAv during stimulation were mitigated in the SCI group (6% ± 6%) vs. AB (29% ± 12%, P < 0.001). Heart rate and end-tidal carbon dioxide responded similarly between groups. CONCLUSIONS Clearly, NVC is impaired in those with SCI. This study may provide a link between poor perfusion of the posterior cerebral region (containing the medullary autonomic centres) and autonomic dysfunction after SCI.

Abstract
Cardiovascular autonomic failure is the second most common dysautonomic feature of α-synucleinopathies and has significant impact on daily activities and quality of life. Here we provide a systematic review of cardiovascular autonomic failure in α-synucleinopathies, emphasizing its impact on cognitive functions and disease outcomes. Articles spanning the period between January 1985 and April 2012 were identified from the PubMed database using a keyword-based search. Epidemiological studies highlight the negative prognostic effect of cardiovascular autonomic failure on cardiovascular and cerebrovascular outcomes and overall mortality in all α-synucleinopathies. Altered cerebral perfusion, vascular pressure stress, and related disruption of the blood-brain barrier may also contribute to the white matter hyperintensities and cognitive dysfunction frequently found in patients affected by neurocardiovascular instability. These findings support the hypothesis that cardiovascular autonomic failure may play a negative prognostic role in α-synucleinopathies and suggest that precocious screening and therapeutic management of cardiovascular autonomic failure may positively impact disease course.

Abstract
Most definitions of frailty utilize US populations in their development. The concept of frailty has not been well studied in Japan, which has the largest percentage of older patients (per capita) in the world. We created a 5-year prospective cohort study of community-dwelling older Japanese adults. Participants were not frail at baseline, based on our definition adapted from the Canadian Study for Health and Aging Clinical Frailty Scale. Participants underwent a comprehensive geriatric assessment (CGA) at baseline, and final assessments were either in person or via mailed survey. We enrolled 407 individuals (184 men, mean age 78 ± 4 years; 223 women, mean age 77 ± 4 years). Sixty-five participants met criteria for frailty by the end of the study. In univariate analyses, eighteen separate parameters were associated with frailty, some of which included: age, gender, handgrip, timed walk, systolic blood pressure, pulse pressure, cognitive status, living alone, and hearing deficits. In multivariate analyses, the following elements remained associated with frailty: timed walk, pulse pressure, cognition deficits and hearing deficits. We established cut-off points for timed walk (5m/3s) and pulse pressure (60 mmHg). We then created a simple additive score for these four factors (present = 1; absent = 0). A score of 0 had a 93% negative predictive value for frailty while a score of 4 had a 70% positive predictive value. While further study is needed, this work creates an easy-to-administer tool that may be generalizable to other populations.

Abstract
BACKGROUND Our aim was to assess whether cardiac hypertrophy is associated with cognitive function independently of office, 24-h, or sleep blood pressure (BP) levels in older hypertensive patients treated with antihypertensive medications. METHODS In this cross-sectional study, we recruited 443 hypertensive patients aged over 60 years (mean age: 73.0 years; 41% men) who were ambulatory, lived independently, and were without clinically overt dementia. They underwent measurements of 24-h BP monitoring, echocardiographic left ventricular mass index (LVMI), and cognitive function (mini-mental state examination, MMSE). RESULTS MMSE score was inversely associated with office, 24-h, awake, and sleep systolic BP (SBP) (each, P < 0.05). There was a close association between MMSE score and LVMI (ρ = -0.32; P < 0.001). Using multiple logistic regression analysis including numerous covariates (i.e., age, sex, obesity, current smoking, educational level, duration of antihypertensive medications, renal dysfunction, statin use, and previous history of cardiovascular disease), the odds ratio (OR) for the presence of cognitive dysfunction, defined as the lowest quartile of MMSE score (median MMSE score: 23 points; n = 115), was estimated; the presence of cardiac hypertrophy (LVMI ≥125 kg/m(2) in men and ≥110 kg/m(2) in women) as well as uncontrolled 24-h BP (mean 24-h SBP/diastolic BP (DBP) ≥130/80 mm Hg) or sleep BP (mean sleep SBP/DBP ≥120/70 mm Hg), but not uncontrolled office BP (mean office SBP/DBP ≥140/90 mm Hg), were independently associated with cognitive dysfunction (all P < 0.05). CONCLUSIONS Among older hypertensive patients with antihypertensive medications, those who had echocardiographically determined cardiac hypertrophy may be at high risk for cognitive dysfunction, irrespective of their office BP and 24-h BP levels.

Abstract
The accurate measurement, prediction and treatment of high blood pressure (BP) are essential issues in the management of hypertension. Ambulatory blood pressure monitoring (ABPM) has been shown to be superior to clinic BP measurements as ABPM can provide the following important information: (i) the mean BP levels, (ii) the diurnal variation in BP and (iii) the short-term BP variability. Among these parameters, there is increasing evidence that the mean nocturnal BP level is the most sensitive predictor of cardiovascular morbidity and mortality. Furthermore, several studies have shown that less nocturnal BP dipping, defined as less nocturnal BP decline relative to daytime BP, or a high night-day BP ratio was associated with poor prognosis irrespective of the 24-hour BP levels. These findings can be interpreted in at least two ways: namely, high nocturnal BP or less nocturnal BP dipping might be not only a potent risk factor for cardiovascular disease (CVD), but also a marker of pre-existing or concurrent diseases that can lead to nocturnal BP elevation. In this review, we consider the clinical utility of ABPM and in particular focus on the nocturnal BP levels or nocturnal BP dipping as a potent risk factor for CVD. In addition, the clinical management of high nocturnal BP and blunted nocturnal BP dipping with antihypertensive medications is discussed.

Abstract
AIM. Prevalence, correlates and reproducibility of nocturnal hypertension (NH) as defined by fixed cut-off limits in uncomplicated essential hypertension are poorly defined. Therefore, we assessed such issue in a cohort of 658 untreated hypertensives. METHODS. All subjects underwent procedures including cardiac and carotid ultrasonography, 24-h urine collection for microalbuminuria, ambulatory blood pressure monitoring (ABPM), over two 24-h periods within 4 weeks. NH was defined according to current guidelines (i.e. night-time blood pressure, BP ? 120/70 mmHg) and non-dipping status as a reduction in average systolic (SBP) and diastolic BP (DBP) at night lower than 10% compared with daytime values. RESULTS. A total of 477 subjects showed NH during the first and second ABPM period; 62 subjects had normal nocturnal BP (NN) in both ABPM sessions. Finally, 119 subjects changed their pattern from one ABPM session to the other. Overall, 72.5% of subjects had reproducible NH, 18% variable pattern (VP) and 9.5% reproducible NN. In the same group, figures of reproducible non-dipping, variable dipping and reproducible dipping pattern were 24%, 24% and 52%, respectively. Among NH patients, 56% of whom were dippers, subclinical cardiac organ damage was more pronounced than in their NN counterparts. CONCLUSIONS. In uncomplicated essential hypertensives, NH is a more frequent pattern than non-dipping; NH is associated with organ damage, independently of dipping/non-dipping status. This suggests that options aimed at restoring a blunted nocturnal BP fall may be insufficient to prevent cardiovascular complications unless night-time BP values are fully normalized.
