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.
Fulltext 2022 World Hypertension League, Resolve To Save Lives and International Society of Hypertension dietary sodium (salt) global call to action

Fulltext A profile of hypertension among rural elderly Malaysians

Srinivas P, Wong KS, Chia YC, Poi PJ, Ebrahim S

Southeast Asian J. Trop. Med. Public Health, 1998 Dec;29(4):821-6.
PMID: 10772571

The main objective of this study was to survey the prevalence of hypertension in Malaysians aged 55 years and above who responded to a public health screening campaign in Kuala Langat district, Selangor, Malaysia. The relationship between the detection, treatment and control in the study population was also examined. An epidemiological survey of the elderly was conducted in Kuala Langat, a rural district in Malaysia for a consecutive period of six weeks. The survey was conducted using a standardized questionnaire and interview by trained research assistants. The medical students and nurses were trained on the correct protocol of measuring blood pressure based on the recommendations of the British Hypertension Society. Newly detected persons with blood pressure readings 160/95 mmHg and above, were given a green card to return to the nearest health center for a further 2 visits to check his/her blood pressure. A total of 1,392 people with a mean age of 65 years and comprising of 53.1% males and 46.9% females responded to the health survey. Based on the history 335 (24.1%) of the respondents were known hypertensives and 82.1% of this hypertensive group were on regular treatment. However good control of hypertension was achieved only in 161 (48.1%) of them. Newly detected hypertension was found in 204 (14.6%) of the respondents. The overall prevalence of hypertension in our sample of respondents was 25.6%. There was no significant difference between the sexes and the races in terms of their detection, treatment and control. However there was a significant difference between the persons aged less than 65 years of age and those older than 65 years. There was a large proportion of previously known hypertensives among the survey population. Of those detected, not all were on regular medications and the majority on medications were not well controlled. Education of the public through intensive public health campaigns is vital to improve their knowledge on hypertension and the need for effective control. More community studies are needed to formulate better methods in the detection, treatment and control of hypertension.
Fulltext Accuracy of urinalysis in detection of urinary tract infection in a primary care setting

Othman S, Chia YC, Ng CJ

Asia Pac Fam Med, 2003;2(4):206-212.

Aim: To determine the accuracy of urinalysis in the detection of urinary tract infection (UTI) in symptomatic patients at primary care level. Methods: A cross sectional study was undertaken on 100 patients with symptoms of UTI presenting at the Primary Care Clinic of University Malaya Medical Center, Kuala Lumpur, Malaysia during the months of August to November 1999. Their urine samples were tested simultaneously using urine dipstick, urine microscopy and urine culture. Urine culture was used as the gold standard and UTI was diagnosed when the urine culture showed a bacteria count of >= 105 organisms per mL. The sensitivity and specificity of each test was calculated. Results: The prevalence of UTI was 25% in symptomatic patients. The urine dipstick for leukocyte esterase, nitrite and red blood cell had sensitivities of 76, 56 and 76%, respectively. Their specificities were 60, 81 and 61%, respectively. Urine microscopy for leukocytes, red blood cells and bacterial count had sensitivities of 80, 52 and 84%, while their specificities were 76, 80 and 54%, respectively. Conclusion: The prevalence of UTI in the present study was low despite reported symptoms of UTI. Urinalysis is needed to support the diagnosis of UTI. In the present study, while there is accuracy in the urinalysis (as the sensitivities and specificities of various tests are comparable with other studies); lack of precision in each test because of the wide range of 95% confidence interval make it less reliable. Caution should be made in interpreting each test.

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.
Fulltext Angiotensin receptor neprilysin inhibitor as a novel antihypertensive drug: Evidence from Asia and around the globe

Lin DS, Wang TD, Buranakitjaroen P, Chen CH, Cheng HM, Chia YC, et al.

J Clin Hypertens (Greenwich), 2021 03;23(3):556-567.
PMID: 33305531 DOI: 10.1111/jch.14120

Hypertension is a worldwide epidemic that continues to grow, with a subset of patients responding poorly to current treatment available. This is especially relevant in Asia, which constitutes 61% of the global population. Hypertension in Asia is a unique entity that is often salt-sensitive, nocturnal, and systolic predominant. Sacubitril/valsartan is a first-in-class angiotensin receptor neprilysin inhibitor that was first used in heart failure with reduced ejection fraction. Sacubitril inhibits neprilysin, a metallopeptidase that degrades natriuretic peptides (NPs). NPs exert sympatholytic, diuretic, natriuretic, vasodilatory, and insulin-sensitizing effects mostly via cyclic guanosine monophosphate (cGMP)-mediated pathways. As an antihypertensive agent, sacubitril/valsartan has outperformed angiotensin II receptor type 1 blockers (ARBs), with additional reductions of office systolic blood pressures ranging between 5 and 7 mmHg, in multiple studies in Asia and around the globe. The drug was well tolerated even in the elderly or those with chronic kidney disease. Its mechanisms of actions are particularly attractive for treatment of hypertension in Asia. Sacubitril/valsartan offers a novel, dual class, single-molecule property that may be considered as first-line antihypertensive therapy. Further investigations are needed to validate its safety for long-term use and to explore other potentials such as in the management of insulin resistance and obesity, which often coexist with hypertension in Asia.
Fulltext Antibiotic prescribing for childhood febrile illness by primary care doctors in Malaysia

Teng CL, Hanafi NS, Ng CJ, Chia YC, Atiya AS

J Paediatr Child Health, 2006 Oct;42(10):612-7.
PMID: 16972968 DOI: 10.1111/j.1440-1754.2006.00937.x

AIM: Fever in children, a mostly benign and self-limiting illness, is often viewed with consternation by the care givers. It results in early consultation and excessive use of antipyretics and antibiotics. In this study, we document the prescribing practice of doctors from three primary care settings in Malaysia and identify the predictors of antibiotic prescription.
METHODS: Interview of care givers bringing febrile children (age = 12 years) to three primary care settings: public primary care clinics, private general practice clinics and a university-based primary care clinic.
RESULTS: Data from 649 children were analysed. Mean age of children 4.1 years and 55% were boys. One-third of the children had prior consultation for the same episode of fever. About 80% of the febrile children were diagnosed to have upper respiratory tract infection, viral fever and gastroenteritis. Overall antibiotic prescribing rate was 36.6% (public primary care clinic 26.8%, private general practice clinic 70.0% and university-based primary care clinic 32.2%). Independent predictors of antibiotic prescription were: clinic setting, longer duration of fever (>7 days), higher temperature (>38 degrees C) and the diagnosis of upper respiratory tract infections. After controlling for demographic and clinical factors, antibiotic prescription in private general practice clinic was seven times higher than public primary care clinic (odds ratio 7.1, 95% confidence interval 4.0-12.7), and 1.6 times higher than university-based primary care clinic (odds ratio 1.6, 95% confidence interval 1.0-2.5).
CONCLUSION: Differences in the patients' demographic and clinical characteristics could not adequately explain the high antibiotic prescribing rate in private general practice clinics. This inappropriately high antibiotic prescribing for febrile children in private general practice clinics is a suitable target for future intervention.
Fulltext Applications of artificial intelligence for hypertension management

Tsoi K, Yiu K, Lee H, Cheng HM, Wang TD, Tay JC, et al.

J Clin Hypertens (Greenwich), 2021 03;23(3):568-574.
PMID: 33533536 DOI: 10.1111/jch.14180

The prevalence of hypertension is increasing along with an aging population, causing millions of premature deaths annually worldwide. Low awareness of blood pressure (BP) elevation and suboptimal hypertension diagnosis serve as the major hurdles in effective hypertension management. The advent of artificial intelligence (AI), however, sheds the light of new strategies for hypertension management, such as remote supports from telemedicine and big data-derived prediction. There is considerable evidence demonstrating the feasibility of AI applications in hypertension management. A foreseeable trend was observed in integrating BP measurements with various wearable sensors and smartphones, so as to permit continuous and convenient monitoring. In the meantime, further investigations are advised to validate the novel prediction and prognostic tools. These revolutionary developments have made a stride toward the future model for digital management of chronic diseases.
Fulltext Are doctors assessing patients with hypertension appropriately at their initial presentation?

Wong SL, Lee PY, Ng CJ, Hanafi NS, Chia YC, Lai PS, et al.

Singapore Med J, 2015 Sep;56(9):518-22.
PMID: 26451055 DOI: 10.11622/smedj.2015137

INTRODUCTION: The aim of this study was to determine the extent to which primary care doctors assessed patients newly diagnosed with hypertension for the risk factors of cardiovascular disease (CVD) during the patients' first clinic visit for hypertension. The study also aimed to examine the trend of assessment for CVD risk factors over a 15-year period.
METHODS: This retrospective study was conducted between January and May 2012. Data was extracted from the paper-based medical records of patients with hypertension using a 1:4 systematic random sampling method. Data collected included CVD risk factors and a history of target organ damage (TOD), which were identified during the patient's first visit to the primary care doctor for hypertension, as well as the results of the physical examinations and investigations performed during the same visit.
RESULTS: A total of 1,060 medical records were reviewed. We found that assessment of CVD risk factors during the first clinic visit for hypertension was poor (5.4%-40.8%). Assessments for a history of TOD were found in only 5.8%-11.8% of the records, and documented physical examinations and investigations for the assessment of TOD and secondary hypertension ranged from 0.1%-63.3%. Over time, there was a decreasing trend in the percentage of documented physical examinations performed, but an increasing trend in the percentage of investigations ordered.
CONCLUSION: There was poor assessment of the patients' CVD risk factors, secondary causes of hypertension and TOD at their first clinic visit for hypertension. The trends observed in the assessment suggest an over-reliance on investigations over clinical examinations.
Fulltext Asian management of hypertension: Current status, home blood pressure, and specific concerns in Malaysia

Cardiovascular disease (CVD) accounts for a third of all deaths in Malaysia. The background CV risk of Malaysia is much higher than that of developed countries in the west and in Asia. This high CV mortality is contributed by the high prevalence of CV risk factors especially hypertension which is very prevalent, coupled with low awareness and low control rates. This highlights the importance of home blood pressure measurements (HBPM). HBPM is an important adjunct in the management of hypertension, particularly to identify those unaware as well as white-coat hypertension which is high in treated hypertensive patients in Malaysia. Ownership of HBPM devices in Malaysia is high, and this is an opportunity as well as timely to encourage more use of HBPM. The Malaysian national guidelines do not require HBPM for the diagnosis of hypertension but do recommend HBPM for specific situations. The most commonly prescribed anti-hypertensives are calcium channel blockers, followed by renin-angiotensin system blockers. Despite the wide availability of anti-hypertensive agents, BP control rates remain low. It is important that strategies are in place to ensure that individuals are aware of the need to have their BP monitored regularly and this can be facilitated by the use of HBPM. Hence, there is a plan to develop a local HBPM consensus document. Strategies to reduce salt intake would also be beneficial. In summary, identification of those unaware and better control of BP with the help of HBPM would help reduce the burden of CV mortality and morbidity in Malaysia.
Assessing 10-Year Cardiovascular Disease Risk in Malaysians With Type 2 Diabetes Mellitus: Framingham Cardiovascular Versus United Kingdom Prospective Diabetes Study Equations

Yew SQ, Chia YC, Theodorakis M

Asia Pac J Public Health, 2019 10;31(7):622-632.
PMID: 31535566 DOI: 10.1177/1010539519873487

In this study, we evaluated the performance of the Framingham cardiovascular disease (CVD) and the United Kingdom Prospective Diabetes Study (UKPDS) risk equations to predict the 10-year CVD risk among type 2 diabetes mellitus (T2DM) patients in Malaysia. T2DM patients (n = 660) were randomly selected, and their 10-year CVD risk was calculated using both the Framingham CVD and UKPDS risk equations. The performance of both equations was analyzed using discrimination and calibration analyses. The Framingham CVD, UKPDS coronary heart disease (CHD), UKPDS Fatal CHD, and UKPDS Stroke equations have moderate discrimination (area under the receiver operating characteristic [aROC] curve = 0.594-0.709). The UKPDS Fatal Stroke demonstrated a good discrimination (aROC curve = 0.841). The Framingham CVD, UKPDS Stroke, and UKPDS Fatal Stroke equations showed good calibration (P = .129 to .710), while the UKPDS CHD and UKPDS Fatal CHD are poorly calibrated (P = .035; P = .036). The UKPDS is a better prediction equation of the 10-year CVD risk among T2DM patients compared with the Framingham CVD equation.

Insulin resistance (IR), a metabolic risk factor, is linked to the pathogenetic mechanism of primary hypertension. Detecting IR in the patients with hypertension will help to predict and stratify the added cardiovascular risk, institute appropriate IR management, and manage hypertension optimally. There are many methods for assessing IR, each with distinct advantages and disadvantages. The euglycemic insulin clamp and intravenous glucose tolerance test, gold standards for measuring IR, are used in research but not in clinical practice. Homeostatic model assessment (HOMA-IR), a method for assessing β-cell function and IR, is frequently applied presently, particularly in Asia. Besides, the triglyceride-glucose index (TyG) first published by South American authors showed a good correlation with the insulin clamp technique and HOMA-IR index. This simple, convenient, and low-cost TyG index is of research interest in many countries in Asia and can be used to screen for IR in the Asian hypertensive community.
Fulltext Awareness and prevalence of mammography screening and its predictors--a cross sectional study in a primary care clinic in Malaysia

Yusof A, Chia YC, Hasni YM

Asian Pac J Cancer Prev, 2014;15(19):8095-9.
PMID: 25338990

BACKGROUND: Worldwide, over half a million women died of breast cancer in 2011 alone. Mammography screening is associated with a reduction of 20 to 35% in breast cancer mortality. The aim of this study was to determine the awareness and practice of mammography screening and predictors of its uptake in Malaysian women attending a primary care clinic.

MATERIALS AND METHODS: A cross-sectional study was carried out among women aged 40 to 74 years attending a primary care clinic in Selangor, Malaysia. An assisted structured questionnaire included questions on socio-demography, source of information and level of knowledge. An adapted version of the revised Champion Health Belief Model Scale plus other associated factors for mammography screening up-take were also included as part of the questionnaire. Predictors for mammography screening uptake were only determined in those who were aware about mammography screening. Significant predictors were determined by logistic regression.

RESULTS: 447 women were recruited for this study; 99.1% of them (n: 411) were aware about breast cancer. Only 50.1% (n: 206) had knowledge about mammography screening. Prevalence of clinical breast-examination (CBE) was 23.3% (n: 104) and mammography screening up-take was 13.2% (n: 59). The predictors for the latter were those who have had clinical breast-examination (aOR=17.58, 95%CI: 7.68-39.82) and those aged between 50 to 59 years (aOR=3.94, 95%CI: 1.61-9.66) as well as those aged 60 years and above (aOR=6.91, 95%CI: 2.28-20.94). Good knowledge and positive beliefs about mammography screening were not associated with mammography screening uptake.

CONCLUSIONS: Half of our Malaysian women were aware about mammography screening. However, the uptake of mammography was low. Previous CBE and older age were significant predictors of mammography screening uptake. Increasing CBE services may increase compliance with guidelines.
Fulltext Awareness, knowledge and practice of dyslipidaemia management among postgraduate primary care trainees in Malaysia: a cross-sectional study

Said AH, Chia YC

BMJ Open, 2017 03 01;7(3):e013573.
PMID: 28249849 DOI: 10.1136/bmjopen-2016-013573

OBJECTIVES: Dyslipidaemia is one of the main risk factors for cardiovascular disease, the leading cause of death in Malaysia. This study assessed the awareness, knowledge and practice of lipid management among primary care physicians undergoing postgraduate training in Malaysia.
DESIGN: Cross sectional study.
SETTING: Postgraduate primary care trainees in Malaysia.
PARTICIPANTS: 759 postgraduate primary care trainees were approached through email or hard copy, of whom 466 responded.
METHOD: A self-administered questionnaire was used to assess their awareness, knowledge and practice of dyslipidaemia management. The total cumulative score derived from the knowledge section was categorised into good or poor knowledge based on the median score, where a score of less than the median score was categorised as poor and a score equal to or more than the median score was categorised as good. We further examined the association between knowledge score and sociodemographic data. Associations were considered significant when p<0.05.
RESULTS: The response rate achieved was 61.4%. The majority (98.1%) were aware of the national lipid guideline, and 95.6% reported that they used the lipid guideline in their practice. The median knowledge score was 7 out of 10; 70.2% of respondents scored 7 or more which was considered as good knowledge. Despite the majority (95.6%) reporting use of guidelines, there was wide variation in their clinical practice whereby some did not practise based on the guidelines. There was a positive significant association between awareness and the use of the guideline with knowledge score (p<0.001). However there was no significant association between knowledge score and sociodemographic data (p>0.05).
CONCLUSIONS: The level of awareness and use of the lipid guideline among postgraduate primary care trainees was good. However, there were still gaps in their knowledge and practice which are not in accordance with standard guidelines.
Fulltext Barriers, Enablers, and Perceptions on Dietary Salt Reduction in the Out-of-Home Sectors: A Scoping Review

Michael V, You YX, Shahar S, Manaf ZA, Haron H, Shahrir SN, et al.

Int J Environ Res Public Health, 2021 07 30;18(15).
PMID: 34360392 DOI: 10.3390/ijerph18158099

In this review, we have investigated the perceptions, barriers, and enabling factors that were responsible for a dietary salt reduction in the out-of-home sectors. For this purpose, we examined different knowledge databases such as Google Scholar, Ebscohost, MEDLINE (PubMed), Ovid, and Cochrane Library for research articles from September to December 2020. The inclusion criteria for the research articles were that they had to be published in English and had to be a qualitative or quantitative study that was conducted after 2010. These studies also had to report the various enablers, barriers, and perceptions regarding salt reduction in the out-of-home sectors. After implementing the inclusion criteria, we successfully screened a total of 440 studies, out of which 65 articles fulfilled all the criteria. The perceived barriers that hindered salt reduction among the out-of-home sectors included lack of menu and food variabilities, loss of sales due to salt reduction, lack of technical skills for implementing the salt reduction processes for cooking or reformulation, and an absence of environmental and systemic support for reducing the salt concentration. Furthermore, the enablers for salt reduction included the intervention programs, easy accessibility to salt substitutes, salt intake measurement, educational availability, and a gradual reduction in the salt levels. With regards to the behavior or perceptions, the effect of organizational and individual characteristics on their salt intake were reported. The majority of the people were not aware of their salt intake or the effect of salt on their health. These people also believed that low salt food was recognized as tasteless. In conclusion, the enablers, barriers, and perceptions regarding salt reduction in the out-of-home sectors were multifaceted. Therefore, for the implementation of the strategies, policies, and initiatives for addressing the barriers, the policymakers need to encourage a multisectoral collaboration for reducing the salt intake in the population.
Fulltext COVID-19 and hypertension-evidence and practical management: Guidance from the HOPE Asia Network

Kario K, Morisawa Y, Sukonthasarn A, Turana Y, Chia YC, Park S, et al.

There are several risk factors for worse outcomes in patients with coronavirus 2019 disease (COVID-19). Patients with hypertension appear to have a poor prognosis, but there is no direct evidence that hypertension increases the risk of new infection or adverse outcomes independent of age and other risk factors. There is also concern about use of renin-angiotensin system (RAS) inhibitors due to a key role of angiotensin-converting enzyme 2 receptors in the entry of the SARS-CoV-2 virus into cells. However, there is little evidence that use of RAS inhibitors increases the risk of SARS-CoV-2 virus infection or worsens the course of COVID-19. Therefore, antihypertensive therapy with these agents should be continued. In addition to acute respiratory distress syndrome, patients with severe COVID-19 can develop myocardial injury and cytokine storm, resulting in heart failure, arteriovenous thrombosis, and kidney injury. Troponin, N-terminal pro-B-type natriuretic peptide, D-dimer, and serum creatinine are biomarkers for these complications and can be used to monitor patients with COVID-19 and for risk stratification. Other factors that need to be incorporated into patient management strategies during the pandemic include regular exercise to maintain good health status and monitoring of psychological well-being. For the ongoing management of patients with hypertension, telemedicine-based home blood pressure monitoring strategies can facilitate maintenance of good blood pressure control while social distancing is maintained. Overall, multidisciplinary management of COVID-19 based on a rapidly growing body of evidence will help ensure the best possible outcomes for patients, including those with risk factors such as hypertension.
Fulltext Cardiovascular risk assessment tools in Asia

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.
Fulltext Central blood pressure for the management of hypertension: Is it a practical clinical tool in current practice?

Cheng HM, Chuang SY, Wang TD, Kario K, Buranakitjaroen P, Chia YC, et al.

PMID: 31841279 DOI: 10.1111/jch.13758

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.
Fulltext Characteristics and control of the 24-hour ambulatory blood pressure in patients with metabolic syndrome

Huang JF, Li Y, Shin J, Chia YC, Sukonthasarn A, Turana Y, et al.

PMID: 33629806 DOI: 10.1111/jch.14229

Asian countries are facing an increasing prevalence of metabolic syndrome (MetS), which may aggravate the burden of cardiovascular diseases in this region. MetS is closely associated with ambulatory blood pressure (BP). Patients with MetS, compared to those without, had a twofold higher risk of new-onset office, home, or ambulatory hypertension. Furthermore, the risk of new-onset MetS in patients with white-coat, masked and sustained hypertension was also doubled compared to normotensives. High-risk masked hypertension and blunted nighttime BP dipping are common in patients with MetS, suggesting perfect 24-hour BP control with long-acting antihypertensive drugs and early initiation of combination therapy might be especially important for patients with MetS.
