  1. Fulltext Estimating prevalence of subjective cognitive decline in and across international cohort studies of aging: a COSMIC study
    Röhr S, Pabst A, Riedel-Heller SG, Jessen F, Turana Y, Handajani YS, et al.
    Alzheimers Res Ther, 2020 12 18;12(1):167.
    PMID: 33339532 DOI: 10.1186/s13195-020-00734-y
    BACKGROUND: Subjective cognitive decline (SCD) is recognized as a risk stage for Alzheimer's disease (AD) and other dementias, but its prevalence is not well known. We aimed to use uniform criteria to better estimate SCD prevalence across international cohorts.

    METHODS: We combined individual participant data for 16 cohorts from 15 countries (members of the COSMIC consortium) and used qualitative and quantitative (Item Response Theory/IRT) harmonization techniques to estimate SCD prevalence.

    RESULTS: The sample comprised 39,387 cognitively unimpaired individuals above age 60. The prevalence of SCD across studies was around one quarter with both qualitative harmonization/QH (23.8%, 95%CI = 23.3-24.4%) and IRT (25.6%, 95%CI = 25.1-26.1%); however, prevalence estimates varied largely between studies (QH 6.1%, 95%CI = 5.1-7.0%, to 52.7%, 95%CI = 47.4-58.0%; IRT: 7.8%, 95%CI = 6.8-8.9%, to 52.7%, 95%CI = 47.4-58.0%). Across studies, SCD prevalence was higher in men than women, in lower levels of education, in Asian and Black African people compared to White people, in lower- and middle-income countries compared to high-income countries, and in studies conducted in later decades.

    CONCLUSIONS: SCD is frequent in old age. Having a quarter of older individuals with SCD warrants further investigation of its significance, as a risk stage for AD and other dementias, and of ways to help individuals with SCD who seek medical advice. Moreover, a standardized instrument to measure SCD is needed to overcome the measurement variability currently dominant in the field.

  2. The HOPE Asia Network consensus on blood pressure measurements corresponding to office measurements: Automated office, home, and ambulatory blood pressures

    For adopting recently introduced hypertension phenotypes categorized using office and out of office blood pressure (BP) for the diagnosis of hypertension and antihypertension drug therapy, it is mandatory to define the corresponding out of office BP with the specific target BP recommended by the major guidelines. Such conditions include white-coat hypertension (WCH), masked hypertension (MH), white-coat uncontrolled hypertension (WUCH), and masked uncontrolled hypertension (MUCH). Here, the authors review the relevant literature and discuss the related issue to facilitate the use of corresponding BPs for proper diagnosis of WCH, MH, WUCH, and MUCH in the setting of standard target BP as well as intensive target BP. The methodology of deriving the corresponding BP has evolved from statistical methods such as standard deviation, percentile value, and regression to an outcome-based approach using pooled international cohort study data and comparative analysis in randomized clinical trials for target BPs such as the SPRINT and STEP studies. Corresponding BPs to 140/90 and 130/80 mm Hg in office BP is important for safe and strict achievement of intensive BP targets. The corresponding home, daytime, and 24-h BPs to 130/80 mm Hg in office BP are 130/80, 130/80, and 125/75 mm Hg, respectively. However, researchers have found some discrepancies among the home corresponding BPs. As tentative criterion for de-escalation of antihypertensive therapy as shown in European guidelines was 120 mm Hg in office BP, corresponding home, daytime, and 24-h systolic BPs to 120 mm Hg in office systolic BP are 120, 120, and 115 mm Hg, respectively.
  3. Fulltext The role of renal nerve stimulation in percutaneous renal denervation for hypertension: A mini-review
    Huang HC, Cheng HM, Chia YC, Li Y, Van Minh H, Siddique S, et al.
    J Clin Hypertens (Greenwich), 2022 Sep;24(9):1187-1193.
    PMID: 36196464 DOI: 10.1111/jch.14554
    Recent trials have demonstrated the efficacy and safety of percutaneous renal sympathetic denervation (RDN) for blood pressure (BP)-lowering in patients with uncontrolled hypertension. Nevertheless, major challenges exist, such as the wide variation of BP-lowering responses following RDN (from strong response to no response) and lack of feasible and reproducible peri-procedural predictors for patient response. Both animal and human studies have demonstrated different patterns of BP responses following renal nerve stimulation (RNS), possibly related to varied regional proportions of sympathetic and parasympathetic nerve tissues along the renal arteries. Animal studies of RNS have shown that rapid electrical stimulation of the renal arteries caused renal artery vasoconstriction and increased norepinephrine secretion with a concomitant increase in BP, and the responses were attenuated after RDN. Moreover, selective RDN at sites with strong RNS-induced BP increases led to a more efficient BP-lowering effect. In human, when RNS was performed before and after RDN, blunted changes in RNS-induced BP responses were noted after RDN. The systolic BP response induced by RNS before RDN and blunted systolic BP response to RNS after RDN, at the site with maximal RNS-induced systolic BP response before RDN, both correlated with the 24-h ambulatory BP reductions 3-12 months following RDN. In summary, RNS-induced BP changes, before and after RDN, could be used to assess the immediate effect of RDN and predict BP reductions months following RDN. More comprehensive, large-scale and long term trials are needed to verify these findings.
  4. Fulltext Standardized home blood pressure monitoring: Rationale behind the 722 protocol
    Lin HJ, Pan HY, Chen CH, Cheng HM, Chia YC, Sogunuru GP, et al.
    J Clin Hypertens (Greenwich), 2022 Sep;24(9):1161-1173.
    PMID: 36196472 DOI: 10.1111/jch.14549
    Home blood pressure (HBP) has been recognized as a prognostic predictor for cardiovascular events, and integrated into the diagnosis and management of hypertension. With increasing accessibility of oscillometric blood pressure devices, HBP monitoring is easy to perform, more likely to obtain reliable estimation of blood pressures, and feasible to document long-term blood pressure variations, compared to office and ambulatory blood pressures. To obtain reliable HBP estimates, a standardized HBP monitoring protocol is essential. A consensus regarding the optimal duration and frequency of HBP monitoring is yet to be established. Based on the current evidence, the "722" protocol, which stands for two measurements on one occasion, two occasions a day (morning and evening), and over a consecutive of 7 days, is most commonly used in clinical studies and recommended in relevant guidelines and consensus documents. HBP monitoring based on the "722" protocol fulfills the minimal requirement of blood pressure measurements to achieve agreement of blood pressure classifications defined by office blood pressures and to predict cardiovascular risks. In the Taiwan HBP consensus, the frequency of repeating the "722" protocol of HBP monitoring according to different scenarios of hypertension management, from every 2 weeks to 3 months, is recommended. It is reasonable to conclude that the "722" protocol for HBP monitoring is clinically justified and can serve as a basis for standardized HBP monitoring.
  5. Home blood pressure-centered approach - from digital health to medical practice: HOPE Asia Network consensus statement 2023
    Kario K, Tomitani N, Wang TD, Park S, Li Y, Shin J, et al.
    Hypertens Res, 2023 Dec;46(12):2561-2574.
    PMID: 37605071 DOI: 10.1038/s41440-023-01397-6
    Recent innovations in digital technology have enabled the simultaneous accumulation, and the linking and analysis of time-series big data relating to several factors that influence blood pressure (BP), including biological indicators, physical activity, and environmental information. Various approaches can be used to monitor BP: in the office/clinic; at home; 24-h ambulatory recording; or with wearable and cuffless devices. Of these, home BP monitoring is a reliable and convenient method, and is recommended for hypertension management by current national and international guidelines. This recommendation is based on evidence showing that home BP is an important predictor of cardiovascular, cerebrovascular and kidney disease in patients with hypertension. In addition, lifetime personalized health record (PHR)-based home BP with telemonitoring combined with co-interventions has been shown to lower BP more effectively than the traditional approach based on office BP. Thus, home BP represents a key metric for personalized anticipation medicine, from digital healthcare to digital medicine. This paper summarizes the latest evidence on home BP monitoring and proposes a Hypertension Cardiovascular Outcome Prevention and Evidence in Asia (HOPE Asia) Network consensus on a home BP-centered approach to the management of hypertension.
  6. Fulltext Expert panel consensus recommendations for ambulatory blood pressure monitoring in Asia: The HOPE Asia Network
    Kario K, Shin J, Chen CH, Buranakitjaroen P, Chia YC, Divinagracia R, et al.
    J Clin Hypertens (Greenwich), 2019 Sep;21(9):1250-1283.

    Hypertension is an important public health issue because of its association with a number of significant diseases and adverse outcomes. However, there are important ethnic differences in the pathogenesis and cardio-/cerebrovascular consequences of hypertension. Given the large populations and rapidly aging demographic in Asian regions, optimal strategies to diagnose and manage hypertension are of high importance. Ambulatory blood pressure monitoring (ABPM) is an important out-of-office blood pressure (BP) measurement tool that should play a central role in hypertension detection and management. The use of ABPM is particularly important in Asia due to the specific features of hypertension in Asian patients, including a high prevalence of masked hypertension, disrupted BP variability with marked morning BP surge, and nocturnal hypertension. This HOPE Asia Network document summarizes region-specific literature on the relationship between ABPM parameters and cardiovascular risk and target organ damage, providing a rationale for consensus-based recommendations on the use of ABPM in Asia. The aim of these recommendations is to guide and improve clinical practice to facilitate optimal BP monitoring with the goal of optimizing patient management and expediting the efficient allocation of treatment and health care resources. This should contribute to the HOPE Asia Network mission of improving the management of hypertension and organ protection toward achieving "zero" cardiovascular events in Asia.
  7. Fulltext Guidance on ambulatory blood pressure monitoring: A statement from the HOPE Asia Network
    Kario K, Hoshide S, Chia YC, Buranakitjaroen P, Siddique S, Shin J, et al.
    J Clin Hypertens (Greenwich), 2021 Mar;23(3):411-421.
    PMID: 33319412 DOI: 10.1111/jch.14128
    Hypertension is an important public health issue due to its association with a number of serious diseases, including cardiovascular disease and stroke. The importance of evaluating hypertension taking into account different blood pressure (BP) profiles and BP variability (BPV) is increasingly being recognized, and is particularly relevant in Asian populations given the specific features of hypertension in the region (including greater salt sensitivity and a high rate of nocturnal hypertension). Ambulatory BP monitoring (ABPM) is the gold standard for diagnosing hypertension and assessing 24-hour BP and provides data on several important parameters that cannot be obtained using any other form of BP measurement. In addition, ABPM parameters provide better information on cardio- and cerebrovascular risk than office BP. ABPM should be used in all patients with elevated BP, particularly those with unstable office or home BP, or who are suspected to have white-coat or masked hypertension. ABPM is also an important part of hypertension diagnosis and monitoring in high-risk patients. ABPM needs to be performed using a validated device and good practice techniques, and has a role both in hypertension diagnosis and in monitoring the response to antihypertensive therapy to ensure strict BP control throughout the 24-hour period. Use of ABPM in clinical practice may be limited by cost and accessibility, and practical education of physicians and patients is essential. The ABPM evidence and practice points in this document are based on the Hypertension Cardiovascular Outcome Prevention and Evidence (HOPE) Asia Network expert panel consensus recommendations for ABPM in Asia.
  8. Fulltext Characteristics of hypertension in obstructive sleep apnea: An Asian experience
    Hoshide S, Kario K, Chia YC, Siddique S, Buranakitjaroen P, Tsoi K, et al.
    J Clin Hypertens (Greenwich), 2021 03;23(3):489-495.
    PMID: 33705599 DOI: 10.1111/jch.14184
    Obstructive sleep apnea (OSA) is a risk of hypertension and is associated with cardiovascular disease (CVD) incidence. In Asian countries, the prevalence of OSA is high, as in Western countries. When blood pressure (BP) is evaluated in OSA individuals using ambulatory BP monitoring (ABPM), the BP phenotype often indicates abnormal BP variability, such as increased nighttime BP or abnormal diurnal BP variation, that is, non-dipper pattern, riser pattern, and morning BP surge, and all these conditions have been associated with increased CVD events. Asians have a higher prevalence of increased nighttime BP or morning BP surge than Westerners. Therefore, this review paper focused on OSA and hypertension from an Asian perspective to investigate the importance of the association between OSA and hypertension in the Asian population. Such abnormal BP variability has been shown to be associated with progression of arterial stiffness, and this association could provoke a vicious cycle between abnormal BP phenotypes and arterial stiffness, a phenomenon recognized as systemic hemodynamic atherothrombotic syndrome (SHATS). OSA may be one of the background factors that augment SHATS. An oxygen-triggered nocturnal oscillometric BP measurement device combined with a pulse oximeter for continuous SpO2 monitoring could detect BP variability caused by OSA. In addition to treating the OSA, accurate and reliable detection and treatment of any residual BP elevation and BP variability caused by OSA would be necessary to prevent CVD events. However, more detailed detection of BP variability, such as beat-by-beat BP monitoring, would further help to reduce CV events.
  9. Fulltext Guidance on home blood pressure monitoring: A statement of the HOPE Asia Network
    Kario K, Park S, Buranakitjaroen P, Chia YC, Chen CH, Divinagracia R, et al.
    J Clin Hypertens (Greenwich), 2018 03;20(3):456-461.
    PMID: 29450979 DOI: 10.1111/jch.13216
    Hypertension is an important modifiable cardiovascular risk factor and a leading cause of death throughout Asia. Effective prevention and control of hypertension in the region remain a significant challenge despite the availability of several regional and international guidelines. Out-of-office measurement of blood pressure (BP), including home BP monitoring (HBPM), is an important hypertension management tool. Home BP is better than office BP for predicting cardiovascular risk and HBPM should be considered for all patients with office BP ≥ 130/85 mm Hg. It is important that HBPM is undertaken using a validated device and patients are educated about how to perform HBPM correctly. During antihypertensive therapy, monitoring of home BP control and variability is essential, especially in the morning. This is because HBPM can facilitate the choice of individualized optimal therapy. The evidence and practice points in this document are based on the Hypertension Cardiovascular Outcome Prevention and Evidence (HOPE) Asia Network expert panel consensus recommendations for HBPM in Asia.
  10. Fulltext 2020 Consensus summary on the management of hypertension in Asia from the HOPE Asia Network
    Kario K, Park S, Chia YC, Sukonthasarn A, Turana Y, Shin J, et al.
    J Clin Hypertens (Greenwich), 2020 03;22(3):351-362.
    PMID: 31816164 DOI: 10.1111/jch.13751
    Hypertension professionals from Asia have been meeting together for the last decade to discuss how to improve the management of hypertension. Based on these education and research activities, the Hypertension, brain, cardiovascular and renal Outcome Prevention and Evidence in Asia (HOPE Asia) Network was officially established in June 2018 and includes experts from 12 countries/regions across Asia. Among the numerous research and review papers published by members of the HOPE Asia Network since 2017, publications in three key areas provide important guidance on the management of hypertension in Asia. This article highlights key consensus documents, which relate to the Asian characteristics of hypertension, home blood pressure monitoring (HBPM), and ambulatory blood pressure monitoring (ABPM). Hypertension and hypertension-related diseases are common in Asia, and their characteristics differ from those in other populations. It is essential that these are taken into consideration to provide the best opportunity for achieving "perfect 24-hour blood pressure control", guided by out-of-office (home and ambulatory) blood pressure monitoring. These region-specific consensus documents should contribute to optimizing individual and population-based hypertension management strategies in Asian country. In addition, the HOPE Asia Network model provides a good example of the local interpretation, modification, and dissemination of international best practice to benefit specific populations.
  11. Fulltext Highlights of the 2019 Japanese Society of Hypertension Guidelines and perspectives on the management of Asian hypertensive patients
    Hoshide S, Kario K, Tomitani N, Kabutoya T, Chia YC, Park S, et al.
    J Clin Hypertens (Greenwich), 2020 03;22(3):369-377.
    PMID: 31891452 DOI: 10.1111/jch.13763
    Unlike other international guidelines but in accord with the earlier Japanese Society of Hypertension (JSH) guidelines, the 2019 JSH guidelines ("JSH 2019") continue to emphasize the importance of out-of-office blood pressure (BP) measurements obtained with a home BP device. Another unique characteristic of JSH 2019 is that it sets clinical questions about the management of hypertension that are based on systematic reviews of updated evidence. JSH 2019 states that individuals with office BP

    Ambulatory blood pressure monitoring (ABPM) can measure 24-hour blood pressure (BP), including nocturnal BP and diurnal variations. This feature of ABPM could be of value in Asian populations for preventing cardiovascular events. However, no study has yet investigated regarding the use of ABPM in actual clinical settings in Asian countries/regions. In this study, 11 experts from 11 countries/regions were asked to answer questionnaires regarding the use of ABPM. We found that its use was very limited in primary care settings and almost exclusively available in referral settings. The indications of ABPM in actual clinical settings were largely similar to those of home BP monitoring (HBPM), that is, diagnosis of white-coat or masked hypertension and more accurate BP measurement for borderline clinic BP. Other interesting indications, such as nighttime BP patterns, including non-dipper BP, morning BP surge, and BP variability, were hardly adopted in daily clinical practice. The use of ABPM as treatment guidance for detecting treated but uncontrolled hypertension in the Asian countries/regions didn't seem to be common. The barrier to the use of ABPM was primarily its availability; in referral centers, patient reluctance owing to discomfort or sleep disturbance was the most frequent barrier. ABPM use was significantly more economical when it was reimbursed by public insurance. To facilitate ABPM use, more simplified indications and protocols to minimize discomfort should be sought. For the time being, HBPM could be a reasonable alternative.
  13. Fulltext Target blood pressure and control status in Asia
    Chia YC, Kario K, Turana Y, Nailes J, Tay JC, Siddique S, et al.
    J Clin Hypertens (Greenwich), 2020 Mar;22(3):344-350.
    PMID: 31742891 DOI: 10.1111/jch.13714
    It is widely accepted that hypertension constitutes a significant cardiovascular risk factor and that treating high blood pressure (BP) effectively reduces cardiovascular risk. An important issue in Asia is not just the high prevalence of hypertension, particularly in some countries, but also the low level of awareness and treatment rates in many regions. The 2017 update of the American College of Cardiology/American Heart Association hypertension guidelines raised the question about which BP threshold should be used to diagnose and treat hypertension. Although there is a theoretical rationale for a stricter BP criterion in Asia given the ethnic-specific features of hypertension in the region, the majority of countries in Asia have retained a diagnostic BP threshold of ≥140/90 mm Hg. Although lowering thresholds might make theoretical sense, this would increase the prevalence of hypertension and also markedly reduce BP control rates. In addition, there are currently no data from robust randomized clinical trials of the benefits of the lower targets in preventing cardiovascular disease and reducing cardiovascular risk, particularly in high-risk patients and especially for Asian populations. There is also no defined home BP treatment target level for an office BP treatment target of 130/80 mm Hg. However, in this regard, in the interim, lifestyle modifications, including reducing body weight and salt intake, should form an important part of hypertension management strategies in Asia, while studies on treating at lower BP threshold level in Asians and getting to lower BP targets will be helpful to inform and optimize the management of hypertension in the region.
  14. Fulltext Diversity of and initiatives for hypertension management in Asia-Why we need the HOPE Asia Network
    Kario K, Chia YC, Sukonthasarn A, Turana Y, Shin J, Chen CH, et al.
    J Clin Hypertens (Greenwich), 2020 Mar;22(3):331-343.
    PMID: 31773883 DOI: 10.1111/jch.13733
    The Hypertension Cardiovascular Outcome Prevention and Evidence in Asia (HOPE Asia) Network was set up to improve the management of hypertension in Asia with the ultimate goal of achieving "zero" cardiovascular events. Asia is a diverse continent, and the prevalence of hypertension has increased over the last 30 years. There are a number of Asia-specific features of hypertension and hypertension-related cardiovascular complications, which means that a region-specific approach is needed. White-coat hypertension will become more of an issue over time as Asian populations age, and masked hypertension is more prevalent in Asian than in Western countries. Identifying and treating masked hypertension is important to reduce cardiovascular risk. Abnormal patterns of blood pressure (BP) variability common in Asia include exaggerated early morning BP surge and nocturnal hypertension. These are also important cardiovascular risk factors that need to be managed. Home blood pressure monitoring (HBPM) is an important tool for detecting white-coat and masked hypertension, and monitoring BP variability, and practices in Asia are variable. Use of HBPM is important given the Asia-specific features of hypertension, and strategies are needed to improve and standardize HBPM usage. Development of HBPM devices capable of measuring nocturnal BP along with other information and communication technology-based strategies are key developments in the widespread implementation of anticipation medicine strategies to detect and prevent cardiovascular events in patients with hypertension. Region-wide differences in hypertension prevalence, control, and management practices in Asia highlight the importance of information sharing to facilitate best practices.
  15. Fulltext Comparison of day-to-day blood pressure variability in hypertensive patients with type 2 diabetes mellitus to those without diabetes: Asia BP@Home Study
    Chia YC, Kario K, Tomitani N, Park S, Shin J, Turana Y, et al.
    J Clin Hypertens (Greenwich), 2020 03;22(3):407-414.
    PMID: 31891447 DOI: 10.1111/jch.13731
    Blood pressure variability (BPV) has been shown to be independently associated with cardiovascular (CV) mortality and morbidity. Patients with type 2 diabetes mellitus (T2DM) have also been shown to have increased BPV. We aimed to compare BPV in hypertensive patients with diabetes with those without diabetes. A total of 1443 hypertensive patients measured their blood pressure (BP) twice in the morning and twice before bed at home for a week. Demographic data, history of T2DM, and anti-hypertensive use were captured. Clinic BP was measured twice in the clinic. Control of BP was defined as clinic systolic BP (SBP) <140 mm Hg and home SBP

    PMID: 35172037 DOI: 10.1111/jch.14440
    Asia is a large continent and there is significant diversity between countries and regions. Over the last 30 years, absolute blood pressure (BP) levels in Asia have increased to a greater extent than those in other regions. In diverse Asia-Pacific populations, for choosing an Asia-specific approach to hypertension management is important to prevent target organ damage and cardiovascular diseases. In this consensus document of HOPE Asia Network, we introduce seven action approaches for management of hypertension in Asia.

    PMID: 34981620 DOI: 10.1111/jch.14336
    Cardiovascular disease (CVD) is becoming the most important burden to health care systems in most part of the world, especially in Asia. Aiming at identifying high risk individuals and tailoring preventive treatment, many cardiovascular risk assessment tools have been established and most of them were developed in Western countries. However, these cardiovascular risk assessment tools cannot be used interchangeably without recalibration because of the different risk factor profiles (ie, greater absolute burden of hypertension and lower level of total-cholesterol in Asians and higher prevalence of metabolic disorders in South Asians) and different CVD profiles (higher ratio of stroke/coronary heart disease in Asians) between Western and Asian populations. Original risk models such as Prediction for ASCVD Risk in China (China-PAR) and Japan Arteriosclerosis Longitudinal Study (JALS) score have been developed and well validated for specific countries, while most of countries/regions in Asia are using established models. Due to higher incidence of stroke in Asians, risk factors like hypertension should weigh more in cardiovascular risk assessment comparing with Western populations, but their actual proportions should be based on CVD profiles in specific countries/regions. The authors encourage the development of new cardiovascular risk assessment tools for Asians, if possible. Still, modifying established models with native epidemiological data of risk factor as well as CVD is acceptable in regions where health care resources are insufficient.

  19. Fulltext Current status of adherence interventions in hypertension management in Asian countries: A report from the HOPE Asia Network
    Shin J, Chia YC, Heo R, Kario K, Turana Y, Chen CH, et al.
    J Clin Hypertens (Greenwich), 2020 Dec 17;23(3):584-94.
    PMID: 33350024 DOI: 10.1111/jch.14104
    Adherence continues to be the major hurdle in hypertension management. Since the early 2000s, systematic approaches have been emphasized to tackle multi-dimensional issues specific for each regional setting. However, there is little data regarding implementation of adherence interventions in Asian countries. Eleven hypertension experts from eight Asian countries answered questionnaires regarding the use of adherence interventions according to 11 theoretical domain frameworks by Allemann et al. A four-point Likert scale: Often, Sometimes, Seldom, and Never used was administered. Responses to 97 items from 11 domains excluding three irrelevant items were collected. "Often-used" interventions accounted for 5/9 for education, 1/8 for skills, 1/2 for social/professional role and identity, 1/1 for belief about capabilities, 0/3 for belief about consequences, 2/4 for intentions, 2/9 for memory, attention, and decision process, 11/20 for environmental context and resources, 0/2 for social influences, 0/2 for emotion, and 2/2 for behavioral regulation. Most of them are dependent on conventional resources. Most of "Never used" intervention were the adherence interventions related to multidisciplinary subspecialties or formal training for behavioral therapy. For adherence interventions recommended by 2018 ESC/ESH hypertension guidelines, only 1 in 7 patient level interventions was "Often used." In conclusion, conventional or physician level interventions such as education, counseling, and prescription have been well implemented but multidisciplinary interventions and patient or health system level interventions are in need of better implementation in Asian countries.
  20. Fulltext Hypertension and Dementia: A comprehensive review from the HOPE Asia Network
    Turana Y, Tengkawan J, Chia YC, Hoshide S, Shin J, Chen CH, et al.
    J Clin Hypertens (Greenwich), 2019 08;21(8):1091-1098.
    PMID: 31131972 DOI: 10.1111/jch.13558
    Approximately 365 million people in Asia were classified as elderly in 2017. This number is rising and expected to reach approximately 520 million by 2030. The risk of hypertension and cognitive impairment/dementia increases with age. Recent data also show that the prevalence of hypertension and age-related dementia are rising in Asian countries. Moreover, not many people in Asian countries are aware of the relationship between hypertension and cognitive impairment/dementia. Furthermore, hypertension control is poorer in Asia than in developed countries. Hypertension is known to be a major risk factor for damage to target organs, including the brain. Decreased cognitive function can indicate the presence of target organ damage in the brain. Twenty-four-hour blood pressure profiles and blood pressure variability have been associated with cognitive impairment and/or silent cerebral diseases, such as silent cerebral infarction or white matter lesions, which are predisposing conditions for cognitive impairment and dementia. Hypertension that occurs in midlife also affects the incidence of cognitive impairments in later life. Managing and controlling blood pressure could preserve cognitive functions, such as by reducing the risk of vascular dementia and by reducing the global burden of stroke, which also affects cognitive function.
