Hypertension is an insidious disease which predisposes to cardiovascular complications and if not treated properly can lead to various serious complications. Economic limitations, having additional benefits with few or almost no side effects have made non-pharmacological management of hypertension an attractive approach for dealing with hypertension, in developed and developing countries alike. A MEDLINE search was done for relevant references with emphasis on original studies, randomized controlled trials, and meta-analyses for this review paper. Lifestyle modifications including changes in the dietary pattern, adopting special diets with low sodium, saturated fat and high calcium, magnesium and potassium and trying the new methods like time restricted meal intake which work in tandem with the circadian rhythm are opening new vistas in the field of non-pharmacological management of hypertension. Lifestyle modifications that effectively lower blood pressure are increased physical activity, weight loss, limited alcohol consumption, relaxation techniques of Yoga, Acupuncture, Tai chi, mindfulness-based stress-reduction program, and Transcendental Meditation. Air pollution of the surrounding air is linked with poor health outcomes and is a major contributor to the global burden of disease. Fine particulate matter <2.5 μm in diameter (PM2.5) is strongly associated with cardiovascular morbidity and mortality. Short-term PM exposure (hours to weeks) increases the likelihood of adverse cardiovascular events including myocardial infarction, stroke, and heart failure, and longer-term exposure multiplies that risk. Non-pharmacological methods should be initiated early phase of disease and should be continued with medication. [ABSTRACT FROM AUTHOR]

The prevalence of hypertension varies by country and region, but it remains a leading yet modifiable risk factor of cardiovascular disease. There are many factors that contribute to the burden of hypertension in Asia, a region with diverse ethnicity. It has been shown that sociodemographic variability is related to ethnic differences, thereby emphasizing the importance of hypertension screening and educating at-risk or vulnerable groups. In this review, we describe the ethnic differences in genetic variants, dietary choice, and lifestyle habits, as well as its association with sociodemographic differences, hypertension awareness, and treatment control.

The new Chinese hypertension guideline comprehensively covers almost all major aspects in the management of hypertension. In this new guideline, hypertension remains defined as a systolic/diastolic blood pressure of at least 140/90 mm Hg. For risk assessment, a qualitative approach is used similarly as in previous Chinese guidelines according to the blood pressure level and the presence or absence of other risk factors, target organ damage, cardiovascular complications, and comorbid diseases. The therapeutic target is 140/90 mm Hg in general, and if tolerated, especially in high-risk patients, can be more stringent, that is, 130/80 mm Hg. However, a less stringent target, that is, 150/90 mm Hg, is used in the younger (65-79 years, if tolerated, 140/90 mm Hg) and older elderly (≥80 years). Five classes of antihypertensive drugs, including β-blockers, can be used either in initial monotherapy or combination. The guideline also provided information on the management of hypertension in several special groups of patients and in the presence of secondary causes of hypertension. To implement the guideline recommendations, several nationwide hypertension control initiatives are being undertaken with new technology. The new technological platforms hopefully will help improve the management of hypertension and generate scientific evidence for future hypertension guidelines, including a possible Asian hypertension guideline in the near future.

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 < 140/90 mm Hg do not have normal BP. The final decisions regarding the diagnosis and treatment of hypertension should be performed based on out-of-office BP values together with office BP measurements. For hypertensive adults with comorbidities, the office BP goal is usually <130/80 mm Hg and the home BP goal is <125/75 mm Hg. Recommendations of JSH 2019 would be valuable for not only Japanese hypertensive patients but also Asian hypertensive patients, who share the same features including higher incidence of stroke compared with that of myocardial infarction and a steeper blood pressure-vascular event relationship.

Epidemiologic studies have consistently demonstrated an increased risk of cardiovascular disease during colder temperatures. Hemodynamic changes associated with cold temperature and an increase in thrombogenicity may both account for the increase in cardiovascular risk and mortality. Studies using both in-office and out-of-office BP measurements have consistently shown an elevation in BP during the colder seasons. The large difference in BP between cold and warm months may increase the incidence of hypertension and reduce the hypertension control rate, potentially resulting in increased cardiovascular risk, especially among those at risk of cardiovascular disease. The current trends in global warming and climate change may have a profound impact on the epidemiology of hypertension and cardiovascular disease, as changes in the climate may significantly affect both BP variability and cardiovascular disease, especially in those with high cardiovascular risk and the elderly. Furthermore, climate change could have a significant influence on hypertension in Asia, considering the unique characteristics of hypertensive patients in Asia. As an increase in ambient temperature decreases the mean daytime average and morning surge in BP, but increases the nocturnal BP, it is difficult to predict how environmental changes will affect the epidemiology and prognosis of hypertension in the Asian-Pacific region. However, these seasonal variations in BP could be minimized by adjusting the housing conditions and using anticipation medicine. In this review, we discuss the impact of seasonal variation in the ambient temperature on hypertension and cardiovascular disease and discuss how this may impact the epidemiology of hypertension and cardiovascular disease.

Since noninvasive central blood pressure (BP) measuring devices are readily available, central BP has gained growing attention regarding its clinical application in the management of hypertension. The disagreement between central and peripheral BP has long been recognized. Some previous studies showed that noninvasive central BP may be better than the conventional brachial BP in association with target organ damages and long-term cardiovascular outcomes. Recent studies further suggest that the central BP strategy for confirming a diagnosis of hypertension may be more cost-effective than the conventional strategy, and guidance of hypertension management with central BP may result in less use of medications to achieve BP control. Despite the use of central BP being promising, more randomized controlled studies comparing central BP-guided therapeutic strategies with conventional care for cardiovascular events reduction are required because noninvasive central and brachial BP measures are conveniently available. In this brief review, the rationale supporting the utility of central BP in clinical practice and relating challenges are summarized. [ABSTRACT FROM AUTHOR]

Cardiovascular Disease (CVD) is the leading cause of deaths worldwide, contributing to about 30% of all deaths. Half of the cases of CVD are estimated in Asia, the world's most populous continent. Hypertension, a major modifiable risk factor for CVD, results in more deaths than any other CV risk factors in the Asian regions. The total number of patients with hypertension is likely to grow as the population ages. The proportion of the elderly population aged 65 years or more in Asia is expected to increase from 7.4% in 2015 to 10.9% in 2030. It is important to note that more than half (54%) of the world's population live in Asia. Aside of being the biggest single risk factor for global deaths, hypertension is also an important precursor and most common risk factor of heart failure (HF). An increase in HF prevalence is clearly related to the rapid epidemiological transition caused by changes in lifestyle in Asian countries. However, the availability of data on HF burden and health care delivery is limited in Asia compared with Europe and North America. This reality has driven the working group of Asian experts for example the HOPE Asia Network to concentrate on hypertension as risk factors for CVD, with the mission to improve the management of hypertension resulting in organ protection toward a goal of achieving "ZERO" CV event in Asia. This paper aims to give an overview regarding the heart problems caused by hypertension in Asia, focus on HF. [ABSTRACT FROM AUTHOR]

Hypertension is an important public health concern. The prevalence keeps increasing, and it is a risk factor for several adverse health outcomes including a decline in cognitive function. Recent data also show that the prevalence of hypertension and age-related dementia is rising in Asian countries, including in the oldest old group. This study aims to discuss possible treatments for high blood pressure in the elderly and propose an optimal target for BP relative to cognitive outcomes. This review discusses several studies on related blood pressure treatments that remain controversial and the consequences if the treatment target is too low or aggressive. Longitudinal, cross-sectional, and RCT studies were included in this review. An optimum systolic blood pressure of 120-130 mm Hg is recommended, especially in nondiabetic hypertensive patients with significant risk factors. In the oldest old group of patients, hypertension might have a protective effect. The use of calcium channel blockers (CCB) and angiotensin receptor blocker (ARB) is independently associated with a decreased risk of dementia in older people. However, personalized care for patients with hypertension, especially for patients who are frail or very old, is encouraged. [ABSTRACT FROM AUTHOR]

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.

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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

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 < 135 mm Hg. BPV was based on home SBP measurements. A total of 362(25.1%) hypertensives had diabetes and 47.4% were male. Mean age was 62.3 ± 12.1 years. There was no difference in the mean clinic SBP in both groups (139.9 mm Hg vs 138.4 mm Hg P = .188). However, the mean morning home SBP was significantly higher and control rate lower in hypertensives with diabetes than those without (132.3 ± 15 mm Hg vs 129.7 ± 14.4 mm Hg P = .005, 39.4% vs 47.6% P = .007), respectively. Masked uncontrolled morning hypertension was higher in those with diabetes versus those without (12.8% vs 8.4%, respectively). There was no statistically significant difference in BPV between those with and without diabetes. In summary, clinic SBP was similar in hypertensives with or without diabetes. However, control of BP based on both clinic and home SBP thresholds was poorer in hypertensives with diabetes compared to those without. Masked uncontrolled morning hypertension was higher in those with diabetes than those without. There was no difference in BPV between the two groups. [ABSTRACT FROM AUTHOR]

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.

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. [ABSTRACT FROM AUTHOR]

Despite reductions in hypertension prevalence and improvements in control rates in recent years, almost one-third of all deaths in Singapore are due to cardiovascular disease and that proportion is growing. Ischemic heart disease is the most common cause of cardiovascular death, ahead of stroke. Local data suggest that awareness and support for home blood pressure monitoring (HBPM) is good, but there are reservations about the accuracy of HBPM devices and physicians cited a lack of time and resources to educate patients about HBPM. In addition, there was a knowledge gap around use of HBPM for evaluating treatment response. This is consistent with the emphasis of using HBPM for the diagnosis, rather than monitoring, of hypertension in the Singapore hypertension guidelines. In the absence of specific HBPM thresholds and targets, it is suggested that HOPE Asia Network consensus documents provide the most locally relevant guidance of the use of HBPM. Calcium channel blockers and angiotensin receptor blockers are the most commonly used antihypertensive agents in Singapore, and monotherapy was relatively uncommon (24%) of patients. Overall, more needs to be done in detecting and managing hypertension in Singapore to address rates of cardiovascular disease and cardiovascular disease mortality. Use of HBPM needs to be encouraged to improve adherence to treatment and optimize BP targets according to Asian perspectives and data. [ABSTRACT FROM AUTHOR]

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.
