Kumar Roy T, Rahman M, Rahman MS, Halder N, Rashid MM. Is gender a factor in socioeconomic disparities in undiagnosed, and untreated hypertension in Bangladesh? J Clin Hypertens (Greenwich) 2024; 26:964-976. [PMID: 38953454 PMCID: PMC11301445 DOI: 10.1111/jch.14858] [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: 03/14/2024] [Revised: 05/27/2024] [Accepted: 06/06/2024] [Indexed: 07/04/2024]
Abstract
Our objectives were to ascertain the following: (1) the prevalence and socioeconomic distribution of hypertension (HTN), undiagnosed for HTN, and untreated cases of HTN-diagnosed individuals; (2) the relationship between SES and the prevalence of HTN, undiagnosed for HTN, and untreated for HTN; and (3) whether sex moderate this association. Data from the 2017-18 Bangladesh Demographic Health Survey were used. 11,776 participants who were 18 years of age or older responded to our analysis. The age-adjusted prevalence of HTN, undiagnosed for HTN, and untreated cases was 25.1%, 57.2%, and 12.3%. Compared to females, males were less likely to have HTN but more likely to have undiagnosed HTN. People in the rich SES groups had a higher odd of (adjusted odds ratio [aoR] 1.25; 95% confidence interval [CI] 1.08-3.45) of having HTN compared to those in the poor SES group. When compared to individuals in the poor SES group, those in the rich SES group had lower odds of undiagnosed (aoR 0.57; 95% CI 0.44-0.74) and untreated (aoR 0.56; 95% CI 0.31-0.98) for HTN. Sex moderated the association between SES and HTN prevalence, which showed that men from rich SES were more likely to suffer from HTN than men from poor SES. According to this study, the government and other pertinent stakeholders should concentrate more on developing suitable policy measures to reduce the risk of HTN, particularly for men in rich socioeconomic groups. They should also concentrate on screening and diagnosing HTN in socioeconomically disadvantaged populations, regardless of sex.

Abstract
The term RH describes a subgroup of hypertensive patients whose BP is uncontrolled despite the use of at least three antihypertensive drugs in an appropriate combination at optimal or best tolerated doses. True RH is considered when appropriate lifestyle measures and treatment with optimal or best tolerated doses of three or more drugs (a thiazide/thiazide-like diuretic, plus renin-angiotensin system -RAS- blocker and a calcium channel blocker -CCB-) fail to lower office BP to <140/90 mmHg; besides the inadequate BP control should be confirmed by home blood pressure monitoring (HBPM) or 24-hour ambulatory; and evidence of adherence to therapy and exclusion of secondary causes of hypertension are required. RH patients are at a high risk of cardiovascular events and death. RH is associated with a higher prevalence of end-organ damage. When stricter criteria are applied, a reasonable estimate of the prevalence of true RH is 5 % of the total hypertensive population. The predominant hemodynamic pattern appears to be increased systemic vascular resistance and plasma volume with normal or even low cardiac output. We must rule out pseudo-resistance before diagnosing true drug resistance. RH is a therapeutic challenge, and its management includes lifestyle interventions, avoiding nonadherence to treatment, avoiding inertia, appropriate use of antihypertensive drugs based on current evidence, especially long-acting diuretics, and the addition of mineralocorticoid receptor antagonists. RCTs to identify the most protective medical therapy in RH are needed. A series of drugs in different stages of investigation could significantly impact RH treatment in the future.

Abstract
Introduction The overall prevalence of hypertension is high, and many people are unaware of their condition. Screening campaigns can effectively identify this group of patients. The study aimed to determine the cost of manpower for a health campaign for detecting undiagnosed hypertension and the prevalence of hypertension. Method This cross-sectional study was conducted at two health centres. Sociodemographic characteristics, hypertension and treatment statuses were recorded. Blood pressure (BP) was measured by either doctors or nurses using automated BP machines. The cost of manpower was calculated as the average salaries of manpower during the 3-day health campaign divided by the total number of days. The final sum was the cost of detecting undiagnosed hypertension. Results A total of 2009 participants median age = 50 (IQR = 18-91) were included in the study. The overall prevalence of hypertension was 41.4% (n=832). Among the patients with hypertension, 49.2% (n=409) were unaware of their hypertension status. Conversely, 21.1% (n=423) were known to have hypertension, among whom 97.4% (n=412) were on medications. Among those who were on medications, 49% (n=202) had good BP control. The average total cost of manpower during the 3-day health campaign was RM 5019.80 (USD 1059). The cost of detecting an individual with elevated BP was RM 12.27 (USD 2.59). Conclusion The prevalence of hypertension and unawareness is high. However, the average cost of manpower to detect an individual with elevated BP is low. Therefore, regular public health campaigns aiming to detect undiagnosed hypertension are recommended.

Abstract
BACKGROUND Hypertension (high blood pressure) is a modifiable risk factor for cardiovascular disease. However, patients may lack confidence in their understanding of what constitutes normal/healthy blood pressure, potentially affecting intentions to seek necessary care. The American Heart Association defines normal/healthy blood pressure as <120/80 mm Hg, with a 130/80 mm Hg threshold for hypertension diagnosis. METHODS Our US sample (N = 6,592) included 1,342 adults with hypertension alone and 795 with hypertension and relevant comorbidities (heart disease, kidney disease, and diabetes mellitus). We assessed confidence in understanding blood pressure numbers, knowledge of thresholds for normal/healthy blood pressure ("normal or healthy blood pressure is below . . ."; counting 120-130/80 mm Hg as correct), and intentions to seek care for randomly assigned blood pressure readings of 142/91 (stage 2 hypertension), 132/69 (stage 1 hypertension), or 118/78 mm Hg (normal/healthy blood pressure). RESULTS Among nonhypertensive participants, 55% expressed confidence in their understanding of blood pressure numbers, but only 36% knew the upper thresholds for normal/healthy blood pressure. Among participants with hypertension alone, 78% were confident while 47% were knowledgeable. Among participants with hypertension and comorbidities, 81% were confident and 40% were knowledgeable. Participants who were confident (v. not) were more likely to express intentions to act on stage 2 hypertension readings but less likely to express intentions to act on stage 1 readings, even after adjustment for knowledge, hypertension diagnosis, and sociodemographics. LIMITATIONS Confidence, knowledge, and intentions were each measured with 1 question. CONCLUSIONS Independent of knowledge, confidence was associated with greater willingness to act on stage 2 hypertension readings but reduced willingness to act on stage 1 hypertension readings. Interventions aiming to improve hypertension care-seeking behavior should improve confidence in accurate knowledge. HIGHLIGHTS Hypertension or high blood pressure is a major risk factor for heart disease.Most Americans do not know that normal/healthy blood pressure levels are ≤120/80 mm Hg, yet they are confident that they know this information.Inappropriate confidence in understanding of blood pressure numbers undermines intentions to seek care for stage 1 hypertension blood pressure readings.

Abstract
Hypertension is a leading cause of cardiovascular disease and despite established strategies to lower blood pressure, the control of hypertension remains poor. This is true even in high-income countries with well-established welfare and medical systems. Among the social factors associated with hypertension (i.e., social determinants of hypertension, SDHT), individual socioeconomic status (SES), including education, income, and occupation, can be crucial for hypertension management (prevalence, awareness, treatment, and control). This article reviews the findings of recently published studies that examined the association between SES and hypertension management in high-income countries. It also discusses social prescribing, which targets social isolation and loneliness as modifiable SDHT to improve hypertension management.

Abstract
BACKGROUND Resistant hypertension is associated with cardiovascular morbidity and mortality. The objective of this study was to estimate the prevalence of apparent treatment-resistant hypertension in Canadian adults and examine the characteristics of those affected. METHODS A nationally-representative, cross-sectional study was conducted using Canadian Health Measures Survey (2007-2017) data. The frequency of respondents with uncontrolled blood pressure despite 3 or more antihypertensive medications of different drug classes (and at least one agent being a diuretic), or treatment with 4 or more agents, irrespective of blood pressure, was determined. RESULTS A total of 245,700 people were identified to have apparent treatment-resistant hypertension, representing 5.3% (95% confidence intervals [CI], 4.5% to 6.2%) of adults treated for hypertension in Canada. Respondents who had uncontrolled blood pressure with 3 or more antihypertensive drugs were more likely women (55.8% [95% CI, 41.1% to 70.4%]), 70 years of age or older (45.3% [95% CI, 32.8-57.9]), and overweight or obese (84.2% [95% CI, 72.3% to 96.1%]). Respondents with apparent treatment-resistant hypertension also had a high likelihood of chronic kidney disease (36.0% [95% CI, 21.4% to 50.6%]), diabetes (35.2% [95% CI, 21.7% to 48.7%]), dyslipidemia (68.0% [95% CI, 55.2% to 80.8%]), and previous history of heart attack (9.9% [95% CI, 4.8% to 15.1%]) or stroke (7.1% [95% CI, 0 to 14.4%]). CONCLUSIONS Despite being prescribed at least 3 antihypertensive drugs, a considerable proportion of Canadians, especially women, have difficulty achieving blood pressure control, predisposing them to a higher risk of cardiovascular complications and death.

Abstract
Globally, cardiovascular diseases (CVDs) are the leading cause of death. Viewed as a threat to the global economy, the United Nations included reducing noncommunicable diseases, including CVDs, in the 2030 sustainable development goals, and the World Health Assembly agreed to a target to reduce noncommunicable diseases 25% by the year 2025. In response, the World Health Organisation led the development of HEARTS, a technical package to guide governments in strengthening primary care to reduce CVDs. HEARTS recommends a public health and health system approach to introduce highly simplified interventions done systematically at a primary health care level and has a focus on hypertension as a clinical entry point. The HEARTS modules include healthy lifestyle counselling, evidence-based treatment protocols, access to essential medicines and technology, CVD risk-based management, team-based care, systems for monitoring, and an implementation guide. There are early positive global experiences in implementing HEARTS. Led by the Pan American Health Organisation, many national governments in the Americas are adopting HEARTS and have shown early success. Unfortunately, in Canada hypertension control is declining in women since 2010-2011 and the dramatic reductions in rates of CVD seen before 2010 have flattened when age adjusted and increased for rates that are not age adjusted, and there are marked increases in absolute numbers of Canadians with adverse CVD outcomes. Several steps that Canada could take to enhance hypertension control are outlined, the core of which is to implement a strong governmental nongovernmental collaborative strategy to prevent and control CVDs, focusing on HEARTS.

Abstract
Many unexplained sex differences have been observed in blood pressure (BP) related morbidity. However, there has been little research about the most obvious difference between men and women-body size. Given that blood vessels are organs of tubular shape, we hypothesized that correction of BP for body surface area (BSA), a two-dimensional measurement of body size, would allow comparison of BP load between men and women. We assessed the relationship of 24-h ambulatory BP measurements and BSA in 534 participants (mean age 61 ± 3 years, 51% women) from the Helsinki Birth Cohort Study. The study subjects had no previous medication affecting vasculature or BP. When BP values were adjusted for age, smoking, physical activity, and body fat percentage, males had higher ambulatory daytime mean systolic BP (131 mmHg vs. 127 mmHg, p < 0.001), diastolic BP (83 mmHg vs. 78 mmHg, p < 0.001), and mean arterial pressure (100 mmHg vs. 96 mmHg, p < 0.001) than females. However, all BP components per unit of BSA were significantly lower in males: daytime mean systolic BP (65 mmHg vs. 71 mmHg, p < 0.001), diastolic BP (41 mmHg vs. 44 mmHg, p < 0.001), pulse pressure (24 mmHg vs. 28 mmHg, p = 0.013), and mean arterial pressure (49 mmHg vs. 54 mmHg, p < 0.001). The same phenomenon was observed in night-time BP values. BP load per BSA is higher in women than in men, which may explain many reported sex differences in cardiovascular morbidity. Relatively small-sized individuals might benefit from a more aggressive therapeutic strategy.

Abstract
Background This study explored both the evolution of the information needs and the perceived relevance of different health information sources in patients with essential hypertension. It also investigated the relationships between information needs and the perceived relevance of information sources with socio-demographic and clinical variables. Methods Two hundred and two patients with essential arterial hypertension were enrolled in the study and evaluated at baseline and during three follow-ups at 6, 12 and 24 months after baseline. Patients had a mean age of 54.3 years [range 21–78; SD = 10.4], and 43% were women. Repeated measures ANOVA, Bonferroni post hoc tests, and Cochran’s Q Test were performed to test differences in variables of interest over time. Results It was observed a significant reduction in all the domains of information needs related to disease management except for pharmacological treatment and risks and complications. At baseline, patients reported receiving health information primarily from specialists, general practitioners, relatives, and television, but the use of these sources decreased over time, even if the decrease was significant only for relatives. Multiple patterns of relationships were found between information needs and the perceived relevance of sources of information and socio-demographics and clinical variables, both at baseline and over time. Conclusions The findings showed a general decrease in both the desire for information and the perceived relevance of different information sources. Hypertensive patients appeared to show little interest in health communication topics as their disease progressed. Understanding patients’ information needs and the perceived relevance of different information sources is the first step in implementing tailored communication strategies that can promote patients’ self-management skills and optimal clinical outcomes.

Abstract
OBJECTIVES To compare clinical characteristics, medical activity, and family and social characteristics of individuals with controlled and uncontrolled hypertension. METHODS This was an observational study on an alphabetically organized randomized sample of individuals suffering from hypertension in a primary care setting followed by 25 general practitioners at three clinics in the Central region of Portugal in mid-2018. Electronic medical records of individuals with an ICPC-2 classification of hypertension were analyzed. Epidemiologic, family, social and therapeutic data were gathered for descriptive and inferential analysis. RESULTS From a total population of 8750 patients classified as having hypertension, a representative sample of 387 individuals (n=369 required for a 95% confidence interval and 5% error margin) was studied. The incidence of uncontrolled hypertension was 56.1%, significantly higher among those living alone (p=00.24) or in a nuclear family (p=0.011), in lower socioeconomic classes (p=0.018), and prescribed anti-inflammatory drugs (p=0.018). The calculated cardiovascular risk was no higher for uncontrolled hypertension (p=0.116). Therapeutic inertia was not found either in number of medicines or in their association (p=0.274). No other studied variables showed a significant difference. Binary logistic regression revealed that living alone or in a nuclear family, and in a family with low socioeconomic level, were associated with uncontrolled hypertension, this model representing 9.6% of the likelihood of having uncontrolled hypertension. CONCLUSIONS Medical activity in general practice and other settings should, in the light of these findings, ally therapeutic competencies with knowledge gained from studying individual, family and social characteristics in order to improve blood pressure control.

Abstract
Resumo O objetivo deste estudo foi investigar prevalências de falhas no diagnóstico, no uso de anti-hipertensivos e na eficácia do tratamento medicamentoso da hipertensão, e a associação destes parâmetros com variáveis sociodemográficas, de saúde e acesso ao serviço de saúde em idosos não institucionalizados. O estudo foi descritivo, transversal, com 3478 idosos, analisados separadamente em regiões Norte/Nordeste e Sul/Sudeste. Utilizou-se a regressão múltipla de Poisson para estimar razões de prevalência brutas e ajustadas pelo tipo de serviço de saúde utilizado. Do total, 29,6% dos idosos apresentaram falhas no diagnóstico, 4,6% no uso de anti-hipertensivos e 65,3% na eficácia medicamentosa. A falha no diagnóstico associou-se ao sexo masculino, menos morbidades, ter um companheiro, raça/cor branca, ter acesso ao convênio ou serviço privado de saúde, possuir renda pessoal inferior/média e ainda trabalhar. A falha no uso de anti-hipertensivos esteve associada à renda pessoal inferior/média e trabalhar. As falhas no manejo da hipertensão são prevalentes em idosos não institucionalizados. Há necessidade de ações que minimizem os impactos negativos destas insuficiências em saúde, em um país com diferenças sociais, econômicas e étnicas.

Awareness of hypertension and related factors in northeastern China: a cross-sectional study. J Hum Hypertens 2019; 34:43-50. [PMID: 31548618 DOI: 10.1038/s41371-019-0263-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2019] [Revised: 06/26/2019] [Accepted: 07/17/2019] [Indexed: 12/13/2022]
Abstract
Timely awareness of hypertension is among the most crucial components in reducing the burden of hypertension. However, there is limited information about the awareness of hypertension in northern China. Therefore, in this cross-sectional study, we aimed to investigate the awareness of hypertension and its associated factors in the Jilin province in China; the study was conducted between July 2014 and December 2015 in four cities and four rural counties in the Jilin province as part of a national study. A stratified multistage random-sampling method was used to select a representative sample: a total of 15,206 participants aged ≥15 years were initially recruited, among which 14,956 were finally included in the survey. The awareness of hypertension in the Jilin province was found to be 42.3%. Moreover, the awareness of hypertension was associated with age, sex, region, marital status, body mass index, and family history of hypertension or coronary artery disease. Employment was associated with a lower awareness in rural areas, whereas high education was associated with a higher awareness in urban areas. Policies targeting specific subgroups may be helpful in increasing the awareness of hypertension in the Jilin province.

Abstract
BACKGROUND Previous studies in Nepal noted an alarming increase in prevalence of hypertension. However, these studies were geographically sparse and coverage of population, mostly limited to single site. The current study fills this gap by examining the current status of prevalence, awareness, treatment and control of hypertension, using recently collected population-based data. METHODS We used the Nepal Demographic Health Survey 2016 data. Sample selection was based on stratified two-stage cluster sampling in rural areas and three stages in urban areas. Blood pressure was measured in all women and men aged 15 and above. RESULTS A total of 13 598 participants: 5593 men and 8005 women aged 15-69 had their blood pressures measured. Overall, 18% (95% CI 16.7-19.2) of the participants aged 15-69 years were hypertensive. Prevalence of hypertension was more among men (22%; 95% CI 21.1-23.5), aged 45-69 years (34%), with no formal education (22%), richest quintile (25%), formerly/ever married (32%), urban dwellers (19%), residents of Province 4 (24%), residents of hills (21%), and obese (41.6%). Among the total hypertensive individuals, only 38% were aware of their hypertensive status and 18% were taking antihypertensive medication. Only half of the hypertensive participants on treatment (52%) had their blood pressure under control. CONCLUSION This nationally representative survey data showed that the prevalence of hypertension is high in Nepal, whereas its awareness, treatment and control rates are low at entire population level.

Abstract
OBJECTIVE Association of lifestyle modification and pharmacological adherence among patients with hypertension attending a national referral hospital in Kenya. DESIGN Descriptive, cross-sectional. SETTING Medical wards and outpatient clinic of a national referral hospital. PARTICIPANTS Patients (n=229) diagnosed with primary hypertension for at least 6 months. PRIMARY OUTCOMES Clinical makers, cholesterol levels, anthropometrics, lifestyle/dietary habits adjusted for age, gender and education; antihypertensive adherence; views on prevention of hypertension and adequacy of hypertension information. RESULTS Ageing was associated with elevated diastolic blood pressure (BP) (p<0.05), heart rate (HR) and cholesterol. Females had higher body mass index (BMI). More males reported drinking alcohol and smoking (p<0.001), especially the highly educated. Higher BPs were observed in smokers and drinkers (p<0.05). Daily vegetables and fruits intake were linked to lower BP, HR and BMI (p<0.05). Intake of foods high in saturated fat and cholesterol were associated with raised HR (p<0.05). Respondents on antihypertensive medication, those engaged in healthy lifestyle and took their prescribed medications had lower mean BPs than those on medication only (138/85 vs 140/90). Few respondents (30.8%) considered hypertension as preventable, mainly the single and highly educated (p<0.05). Respondents (53.6%) believed they should stop taking their antihypertensive medication once hypertension is controlled. CONCLUSION Missed targets for BP control and hypertension-related risks are associated with ageing, female gender, fast food and animal fat intake. Alcohol and smoking is common in males associated with poor BP control. Daily vegetables and fruits intake are associated with better BP control and overall hypertension risk reduction. Observed suboptimal BP control despite pharmacological adherence suggests lifestyle modification is needed besides antihypertensive medication. Interventions should address modifiable risk factors aggravated by age and adverse lifestyles through adopting combined lifestyle modification, pharmacological adherence and tailored expert delivered hypertension-related information.

Prevalence of treatment-resistant hypertension after considering pseudo-resistance and morbidity: a cross-sectional study in Irish primary care. Br J Gen Pract 2018; 68:e394-e400.

Abstract
BACKGROUND To confirm treatment-resistant hypertension (TRH), ambulatory blood pressure measurement (ABPM) must exclude white-coat hypertension (WCH), three or more medications should be prescribed at the optimal doses tolerated, and non-adherence and lifestyle should be examined. Most previous studies have not adequately considered pseudo-resistance and merely provide an apparent TRH (aTRH) prevalence figure. AIM To conduct a cross-sectional study of the prevalence of aTRH in general practice, and then consider pseudo-resistance and morbidity. DESIGN AND SETTING With support, 16 practices ran an anatomical therapeutic chemical (ATC) drug search, identifying patients on any possible hypertensive medications, and then a search of individual patients' electronic records took place. METHOD ABPM was used to rule out WCH. The World Health Organization-defined daily dosing guidelines determined adequate dosing. Adherence was defined as whether patients requested nine or more repeat monthly prescriptions within the past year. RESULTS Sixteen practices participated (n = 50 172), and 646 patients had aTRH. Dosing was adequate in 19% of patients, 84% were adherent to medications, as defined by prescription refill, and 43% had ever had an ABPM. Using a BP cut-off of 140/90 mmHg, the prevalence of aTRH was 9% (95% confidence interval [CI] = 9.0 to 10.0). Consideration of pseudo-resistance further reduced prevalence rates to 3% (95% CI = 3.0 to 4.0). CONCLUSION Reviewing individual patient records results in a lower estimate of prevalence of TRH than has been previously reported. Further consideration for individual patients of pseudo-resistance additionally lowers these estimates, and may be all that is required for management in the vast majority of cases.

Abstract
Objective Health literacy plays a critical role in chronic disease self-management. This study aimed to determine the relation between health literacy levels, hypertension awareness and control among primary-secondary school teachers in Turkey. Materials and Methods This descriptive and cross-sectional research was conducted among school teachers with the participation of 500 volunteer teachers of both genders. The response rate was 86.2%. To determine health literacy levels, the Newest Vital Sign Scale and Blood Pressure Concept Test were used. Results The mean scores of all individuals were 2.12 ± 1.82 over six points although this showed “limited” levels of health literacy. The mean scores obtained from the scale were 2.13 ± 1.83 in non-hypertensives, while it was 2.06 ± 1.77 in hypertensives. Nonetheless, disease knowledge and awareness were low in teachers. Adequate health literacy levels were low according to disease awareness and control. The measured health literacy levels of teachers didn't overlap with their own assessments about health literacy skills. Recommendations Limited health literacy levels in educators gave an impression that our education system was poor in terms of health education programs.

Abstract
OBJECTIVE The aim of this study was to determine Canadian workers' level of awareness about their cardiovascular disease (CVD) risk factors and the association between CVD risk awareness and health behaviors. METHODS We used cross-sectional data to compare awareness of CVD risk factors with biometric measures from a workplace screening clinic (n = 320). We assessed the association between risk factor awareness and self-reported health behaviors using logistic regression analyses. RESULTS Overall, 39.5% of workers did not know at least one of their CVD risk factors. These individuals were less likely to meet recommended physical activity levels and to consume three daily servings of fruits and vegetables, and more likely to report weekly fast food consumption. CONCLUSIONS This study highlights a lack of awareness about cholesterol levels and demonstrates a negative association between low CVD awareness and preventive health behaviors.

Abstract
Objectives: The study aimed to assess the current epidemiology of hypertension, including its prevalence, the awareness of the condition and its treatment and control, in Turkey to evaluate changes in these factors over the last 10 years by comparing the results with the prevalence, awareness, treatment, and control of hypertension in Turkey (PatenT) study data (2003), as well as to assess parameters affecting awareness and the control of hypertension. Methods: The PatenT 2 study was conducted on a representative sample of the Turkish adult population (n = 5437) in 2012. Specifically trained staff performed the data collection. Hypertension was defined as mean SBP or DBP at least 140/90 mmHg, previously diagnosed disease or the use of antihypertensive medication. Awareness and treatment were assessed by self-reporting, and control was defined as SBP/DBP less than 140/90 mmHg. Results: Although the prevalence of hypertension in the PatenT and PatenT 2 surveys was stable at approximately 30%, hypertension awareness, treatment, and control rates have improved in Turkey. Overall, 54.7% of hypertensive patients were aware of their diagnosis in 2012 compared with 40.7% in 2003. The hypertension treatment rate increased from 31.1% in 2003 to 47.4% in 2012, and the control rate in hypertensives increased from 8.1% in 2003 to 28.7% in 2012. The rate of hypertension control in treated patients improved between 2003 (20.7%) and 2012 (53.9%). Awareness of hypertension was positively associated with older age, being a woman, residing in an urban area, a history of parental hypertension, being a nonsmoker, admittance by a physician, presence of diabetes mellitus, and being obese or overweight; it was inversely associated with a higher amount of daily bread consumption. Factors associated with better control of hypertension were younger age, female sex, residing in an urban area, and higher education level in Turkey. Conclusion: Although some progress has been made in recognizing hypertension from 2003 to 2012, there is still a large population of untreated or inadequately treated hypertensives in Turkey. Strengthening of population-based efforts to improve the prevention, early detection, and treatment of hypertension is needed.

Abstract
INTRODUCTION Hypertension is highly prevalent among the elderly. Its awareness has a direct influence on control through drug adherence. Earlier studies have shown that awareness of hypertension is low among sub-Saharan African populations but only a few studies have looked at the prevalence and awareness of hypertension among the elderly. METHODS The Ibadan Study of Ageing is a longitudinal cohort study of the mental and physical health status as well as the functioning of elderly persons residing in the Yoruba-speaking areas of Nigeria. Study was conducted in multiple waves from 2003/2004 to 2009. This report is based on the sample studied in 2007 (N = 1469). Respondents, aged ≥ 65 years, were assessed for the presence of hypertension, its awareness, receipt of and adherence to medication for the condition, and effectiveness of treatment on the control of blood pressure. Blood pressure was measured with the use of digital monitors (Omron MS - 2 Basic Model). Awareness of the diagnosis of hypertension was ascertained by self-reports. We explored social, economic, demographic and clinical correlates of the presence of hypertension, its awareness and control using multiple logistic regression analyses. RESULTS The sample was composed of 809 (55.1%) females and 666 (44.9%) males. The mean age of the participants was 76.9 ± 8.4 years. Hypertension (defined as previous diagnosis by a health provider or a measured blood pressure higher than or equal to 140/90 mm Hg) was recorded in 973 (62.2%) participants, with females having a prevalence of 61.4% and males that of 70.1%. Other than female gender, residing in urban/semi urban areas and being overweight or obesity were associated with the occurrence of hypertension. Among those assessed to have hypertension, 78% were not previously aware of its presence. Factors independently associated with lack of awareness of hypertension included low socioeconomic class (OR 8.21, 95% CI 3.72-18.11, P < 0.001), and BMI >25kg/m2 (OR 3.11, 95% CI 1.36-7.09, P < 0.009). Among those who were aware of the presence of hypertension and were on treatment, 77.3% still had uncontrolled hypertension. Only obesity or overweight (OR 5.56, 95% CI 1.35 - 22.83, P < 0.016) was independently associated with poor blood pressure control. CONCLUSION The prevalence of hypertension among elderly Nigerians is high and those affected are often not aware of having the condition. Only a minority of those who receive treatment for the condition have adequate blood pressure control. The findings highlight the need for improved healthcare for the growing population of elderly persons, with particular attention to early detection and effective control of the condition.

Abstract
Background Established cardiovascular risk factors are highly prevalent and contribute substantially to cardiovascular morbidity and mortality because they remain uncontrolled in many Canadians. Worksite-based cardiovascular risk factor screening and management represent a largely untapped strategy for optimizing risk factor control. Methods In a 2-phase collaborative demonstration project between Alberta Health Services (AHS) and the Alberta Newsprint Company (ANC), ANC employees were offered cardiovascular risk factor screening and management. Screening was performed at the worksite by AHS nurses, who collected baseline history, performed automated blood pressure measurement and point-of-care testing for lipids and A1c, and calculated 10-year Framingham risk. Employees with a Framingham risk score of ≥10% and uncontrolled blood pressure, dyslipidemia, or smoking were offered 6 months of pharmacist case management to optimize their risk factor control. Results In total, 87 of 190 (46%) employees volunteered to undergo cardiovascular risk factor screening. Mean age was 44.5±11.9 years, 73 (83.9%) were male, 14 (16.1%) had hypertension, 4 (4.6%) had diabetes, 12 (13.8%) were current smokers, and 9 (10%) had dyslipidemia. Of 36 employees with an estimated Framingham risk score of ≥10%, 21 (58%) agreed to receive case management and 15 (42%) attended baseline and 6-month follow-up case management visits. Statistically significant reductions in left arm systolic blood pressure (−8.0±12.4 mmHg; p=0.03) and triglyceride levels (−0.8±1.4 mmol/L; p=0.04) occurred following case management. Conclusion These findings demonstrate the feasibility and usefulness of collaborative, worksite-based cardiovascular risk factor screening and management. Expansion of this type of partnership in a cost-effective manner is warranted.

Abstract
BACKGROUND Effective policies to control hypertension require an understanding of its distribution in the population and the barriers people face along the pathway from detection through to treatment and control. One key factor is household wealth, which may enable or limit a household's ability to access health care services and adequately control such a chronic condition. This study aims to describe the scale and patterns of wealth-related inequalities in the awareness, treatment and control of hypertension in 21 countries using baseline data from the Prospective Urban and Rural Epidemiology study. METHODS A cross-section of 163,397 adults aged 35 to 70 years were recruited from 661 urban and rural communities in selected low-, middle- and high-income countries (complete data for this analysis from 151,619 participants). Using blood pressure measurements, self-reported health and household data, concentration indices adjusted for age, sex and urban-rural location, we estimate the magnitude of wealth-related inequalities in the levels of hypertension awareness, treatment, and control in each of the 21 country samples. RESULTS Overall, the magnitude of wealth-related inequalities in hypertension awareness, treatment, and control was observed to be higher in poorer than in richer countries. In poorer countries, levels of hypertension awareness and treatment tended to be higher among wealthier households; while a similar pro-rich distribution was observed for hypertension control in countries at all levels of economic development. In some countries, hypertension awareness was greater among the poor (Sweden, Argentina, Poland), as was treatment (Sweden, Poland) and control (Sweden). CONCLUSION Inequality in hypertension management outcomes decreased as countries became richer, but the considerable variation in patterns of wealth-related inequality - even among countries at similar levels of economic development - underscores the importance of health systems in improving hypertension management for all. These findings show that some, but not all, countries, including those with limited resources, have been able to achieve more equitable management of hypertension; and strategies must be tailored to national contexts to achieve optimal impact at population level.

Abstract
The prevalence and associated factors of untreated, uncontrolled, and apparent-resistant hypertension (RH) in Germany are unknown. Based on European Society of Hypertension criteria, apparent RH was defined as blood pressure (BP) ≥140/90 mm Hg (≥140/85 mm Hg in diabetics) under treatment with three different classes of antihypertensive agents including a diuretic. Data from the German Health Examination Survey (2008-2011; n=7115, age 18-79 years) including standardized BP measurements and Anatomical Therapeutic Chemical-coded taken medications were analyzed. Among patients aware of their hypertensive status (n=2205), 37.9% were uncontrolled and, among those, 33.4% were untreated. Being aware and having untreated and uncontrolled BP was associated with male sex, young age, not having cardiovascular disease, not performing BP self-measurement, not being obese, and not smoking. Apparent RH occurred in 6.8% of treated aware hypertensive patients and was positively associated with having diabetes. The proportion of uncontrolled BP is still high. Not having "obvious risk factors" has become a risk itself for having untreated and uncontrolled hypertension.

The persisting gender gap in hypertension management and control in Germany: 1998 and 2008-2011. Hypertens Res 2016; 39:457-66.

Abstract
Hypertension is a major risk factor for cardiovascular morbidity; therefore, its control is very important. International Guidelines recommend the same hypertension management in men and women; however, studies suggest that management of hypertension differs. This study explores gender-age disparities in the management and control of hypertension in Germany in 1998 and 2008-2011. Data from the German Health Examination Surveys (GNHIES98 1998, n=7124 and DEGS1 2008-2011, n=7988, age 18-79 years), including standardized blood pressure measurements and Anatomical Therapeutic Chemical medication codes, were analyzed by gender and two age groups. For 1998 and 2008-2011 in Germany, the gender gap in hypertension management persisted without significant changes. Hypertensive men in 2008-2011 had lower awareness of their condition (78.3 vs. 86.8%), less treatment for hypertension (65.3 vs. 79.2%), less control of hypertension (45.4 vs. 57.5%) and less treatment among those aware of their condition (83.9 vs. 91.5%) than did women. These gender differences were greater in younger compared with older adults (18-54 years vs. 55-79 years). No gender differences were observed in control of hypertension among those treated in 1998; however, subsequent improvement was less in younger men compared with the other age-gender groups, leading to a new gender gap in 18-54-year olds (women 84.8%, men 63.9%). Younger women used more β-blockers and less angiotensin-converting enzyme inhibitors (ACEI) than younger men. Factors positively associated with control among those treated for hypertension in the younger group were being a woman, using β-blockers or using ACEI, or angiotensin-receptor blockers. In the older group, diabetes was negatively associated with control of hypertension, whereas having cardiovascular comorbidities was positively associated. Gender disparities in hypertension management and control still exist in Germany but may be masked because they are age-dependent.

Abstract
Increasing research into heliobiology and related fields has revealed a myriad of potential relationships between space weather factors and terrestrial biology. Additionally, many studies have indicated cyclicity in incidence of various diseases along with many aspects of cardiovascular function. The current study examined annual mortality associated with hypertensive diseases in Canada from 1979 to 2009 for periodicities and linear relationships with a range of heliophysical parameters. Analyses indicated a number of significant lagged correlations between space weather and hypertensive mortality, with solar wind plasma beta identified as the likely source of these relationships. Similar periodicities were observed for geomagnetic activity and hypertensive mortality. A significant rhythm was revealed for hypertensive mortality centered on a 9.6-year cycle length, while geomagnetic activity was fit with a 10.1-year cycle. Cross-correlograms of mortality with space weather demonstrated a 10.67-year periodicity coinciding with the average 10.6-year solar cycle length for the time period examined. Further quantification and potential implications are discussed.

Abstract
Although hypertension is common among older adults, the optimal blood pressure (BP) for survival in older adults remains unclear. We attempt to use a large cohort to assess the relationship between BP and mortality and to gain insight into what level of BP is required for optimal survival in older adults.A total of 77,389 community-dwelling adults, aged ≥65 years, were followed between 2006 and 2010. Mortality was determined using matching cohort identifications with national death files. Cox proportional hazards regression models were used to evaluate the relationship of BP with all-cause, cardiovascular disease (CVD), and expanded-CVD mortalities.The mortality risks of the stage 2-3 hypertension group were substantial (all-cause mortality: hazard ratio [HR]: 1.23; 95% confidence interval [CI]: 1.10-1.37; CVDs mortality: HR: 1.31; 95% CI: 1.05-1.64; expanded-CVDs mortality: HR: 1.40; 95% CI: 1.15-1.71). The cardiovascular and expanded-cardiovascular mortality risks were lowest when systolic blood pressures were 120 to 129 mm Hg, and increased significantly when systolic blood pressures (SBPs) were ≥160 mm Hg or diastolic BPs were ≥90 mm Hg. A J-curve phenomenon for SBP on CVD and expanded-CVD mortality was observed. The impacts of stage 2-3 hypertension on mortality risks were significantly increased among women. The mortality risks of hypertension were not attenuated with older age.This study provides insight for identifying the optimal BP for survival in older adults, and extends the knowledge of the impacts of hypertension on mortality risks among women and the older adults.

Abstract
Background A large proportion of treated hypertensive subjects do not achieve target blood pressure (BP) levels. We investigated trends in treatment and BP levels in the population, and among treated hypertensive subjects in northern Sweden. Methods The six Northern Sweden MONICA population surveys 1986 to 2009, included 6342 subjects aged 45 to 74 years of age, participation rate 79.3 %. Factors associated with lack of BP control are presented for 1106 participants in 2009. BP control was defined as a systolic BP <140 and a diastolic BP <90 mm Hg among treated hypertensive patients. Results Between 1986 and 2009, the proportion of the population that received antihypertensive treatment increased. The proportion of the whole population having BP <140/90 mm Hg increased for all (p < 0.001 for each subgroup), except for men 45–55 years old. In 2009, 62.4 % of the population had BP <140/90 mm Hg, 67.2 % in women and 58.1 % in men (p = 0.002). In the group of treated hypertensive patients, the proportion having BP control increased (p < 0.001) with no difference between sex or age groups. In 2009 52.1 % of treated hypertensives had BP control. In 2009, adequate BP control among treated hypertensive patients was 63.9 % for those with BMI <25, but only 48.8 % for those with BMI > 25 (p = 0.015). Abdominal obesity was associated with less BP control (48.1 %) than without abdominal obesity (66.2 %, p = 0.007). Women who were physically inactive had better BP control than those who were active (p = 0.03). Men treated with two or more antihypertensive drugs were 50 % more likely to reach target BP than men with monotherapy (60.4 % vs. 40.0 %, p = 0.035). Rural or urban living, level of education, diabetes mellitus or having a high cardiovascular risk were not associated with better BP control. Conclusion Antihypertensive treatment and BP control have increased in northern Sweden since 1986, although in 2009 still barely half of the treated patients achieved adequate BP levels. Intensified treatment and weight reduction may help to further improve BP control.

Abstract
Determine the effectiveness of treatment and the frequency of clinical inertia in the management of hypertension in Colombian patients. A retrospective study with prospective follow-up of individuals on antihypertensive medication who were treated on medical consultation for 1 year was conducted in 20 Colombian cities. Clinical inertia was considered when no modification of therapy occurred despite not achieving control goals. A total of 355 hypertensive patients were included. From a total of 1142 consultations, therapy was effective in 81.7% of cases. In 18.3% of the cases, the control goal was not achieved, and of these, 81.8% were considered clinical inertia. A logistic regression showed that the use of antidiabetics (odds ratio: 2.31; 95% confidence interval: 1.290-4.167; P = .008) was statistically associated with an increased risk of clinical inertia. With a determination of the frequency of inertia and the high effectiveness of antihypertensive treatment, valuable information can be provided to understand the predictors of clinical inertia.

Abstract
Purpose To determine the effect of job insecurity based on repeated measurements on ischemic heart disease (IHD) and on antihypertensive medication. Methods The study population consists of 12,559 employees aged 18–59 years of the Danish Work Environment Cohort Study. With an open cohort design, data from up to four representative waves were linked to four registers. Poisson regression with time-dependent covariates was used to estimate the rate ratio (RR) with confidence interval (CI) of perceived job insecurity associated with first-time IHD hospitalization or mortality 1991–2010 (n = 561 cases) and incident dispensing of prescribed antihypertensive medications 1996–2010 (n = 2,402 cases). Results Participants with perceived job insecurity filled more antihypertensive prescriptions (age-, gender-, and calendar year-adjusted RR 1.23, 95 % CI 1.12–1.33) and had a borderline significant higher IHD incidence (RR 1.23, 95 % CI 0.98–1.55). In a subanalysis, the risk of antihypertensive medication dispensed was only significant among employees with worries about both unemployment and poor reemployment opportunities. After explorative stratifications by age, gender, and occupational status, perceived job insecurity was associated with more dispensing of antihypertensive medications to participants less than 50 years of age. Conclusions In a country with high social security and active labor market policy, employees with the feeling of an insecure job have a modestly increased risk to fill an antihypertensive prescription. Further studies on health risks of job insecurity should consider improved exposure assessment, earlier outcomes such as medication in order to increase statistical power, and identification of vulnerable population groups.

Abstract
BACKGROUND Although treatment-resistant hypertension (RH) is a serious burden on population health, there exists uncertainty about its prevalence. Hence, the objectives of this work were to systematically review and critically appraise the literature and to conduct a meta-analysis on the prevalence of RH in treated hypertensive populations. METHODS PubMed, Cochrane Library, CRD York databases, and study bibliographies were systematically searched for observational and interventional studies that report disease frequency in adult populations. The pooled prevalence was obtained through random-effect modeling. Furthermore, quality assessment, publication bias diagnostics, meta-regression, subgroup analysis by sex, and sensitivity analysis were performed. RESULTS Out of 318 retrieved studies, 20 observational studies and 4 randomized control trials (RCTs) with a total population of 961,035 were included. The random-effect method for observational studies and RCTs yielded RH prevalence ratios of 13.72% (95% confidence interval (CI) = 11.19%-16.24%) and 16.32% (95% CI = 10.68%-21.95%), respectively. Yet, most studies were incapable of ruling out pseudo-resistance caused by white-coat effect, poor medication adherence, and suboptimal dosing. Differences in RH prevalence by sex were negligible. Meta-regression analysis showed that study-level characteristics had no statistically significant influence on RH prevalence. The inclusion of further studies in the sensitivity analysis concurred with the baseline results (13.19%; 95% CI = 10.89%-15.49%). CONCLUSIONS Researchers should enhance comparability of future empirical evidence through homogeneous methodologies and comparable baseline populations. This meta-analysis concludes that RH is a frequent phenomenon and further harmonization in terms of RH definition and measurement would be necessary to clearly distinguish true treatment resistance from pseudo-resistance.

Abstract
Objectives: Controlling blood pressure is a key step in reducing cardiovascular mortality in older adults. Gender differences in patients’ attitudes after disease diagnosis and their management of the disease have been identified. However, it is unclear whether gender differences exist in hypertension management among older adults. We hypothesized that gender differences would exist among factors associated with hypertension diagnosis and control among community-dwelling, older adults. Methods: This cross-sectional study analyzed data from 653 Koreans aged ≥60 years who participated in the Korean Social Life, Health, and Aging Project. Multiple logistic regression was used to compare several variables between undiagnosed and diagnosed hypertension, and between uncontrolled and controlled hypertension. Results: Diabetes was more prevalent in men and women who had uncontrolled hypertension than those with controlled hypertension or undiagnosed hypertension. High body mass index was significantly associated with uncontrolled hypertension only in men. Multiple logistic regression analysis indicated that in women, awareness of one’s blood pressure level (odds ratio [OR], 2.86; p=0.003) and the number of blood pressure checkups over the previous year (OR, 1.06; p=0.011) might influence the likelihood of being diagnosed with hypertension. More highly educated women were more likely to have controlled hypertension than non-educated women (OR, 5.23; p=0.013). Conclusions: This study suggests that gender differences exist among factors associated with hypertension diagnosis and control in the study population of community-dwelling, older adults. Education-based health promotion strategies for hypertension control might be more effective in elderly women than in elderly men. Gender-specific approaches may be required to effectively control hypertension among older adults.

Lotufo PA, Pereira AC, Vasconcellos PS, Santos IS, Mill JG, Bensenor IM. Resistant hypertension: risk factors, subclinical atherosclerosis, and comorbidities among adults-the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). J Clin Hypertens (Greenwich) 2015; 17:74-80. [PMID: 25338543 PMCID: PMC8031839 DOI: 10.1111/jch.12433] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2014] [Revised: 09/04/2014] [Accepted: 09/14/2014] [Indexed: 11/29/2022]
Abstract
The frequency of resistant hypertension-defined as blood pressure (BP) ≥140/90 mm Hg with proven use of three antihypertensive medications, or as the use of four antihypertensive drug classes regardless of BP-is unknown in low-middle-income countries. Using data from the Brazilian Longitudinal Study of Adult Health, a cohort of 15,105 civil servants aged 35 to 74 years, the authors identified 4116 patients taking treatment for hypertension, 11% of who had resistant hypertension. These participants were more likely to be older, black, less educated, poorer, and obese. The adjusted prevalence ratios (95% confidence intervals) were diabetes, 1.44 (1.20-1.72); glomerular filtration rate (<60 mL/min/1.72 m(2) ), 1.95 (1.60-2.38); albumin-to-creatinine ratio (>300 mg/g), 2.43 (1.70-3.50); carotid-femoral pulse-wave velocity, 1.07 m/s (1.03-1.11 m/s); common carotid intima-media thickness, 2.57 mm (1.64-4.00 mm); left ventricular hypertrophy, 2.08 (1.21-3.57); and atrial fibrillation, 3.55 (2.02-6.25). Thus, the prevalence of resistant hypertension in Brazil is high and associated with subclinical markers of end-organ cardiovascular damage.

Abstract
Life expectancy is longer in women compared to men, and cardiovascular events occur at a lower rate and at a later age in females than males. The impact of gender on the prevalence, the presentation, and the long-term outcome of cardiovascular disease has long been a topic of active research. Gender differences have been found in several studies but opposite findings also exist. The impact of gender in hypertension and antihypertensive therapy remains poorly clarified. The prevalence, awareness, treatment, and control rates of hypertension exhibit some differences between the two sexes, which are age-dependent. The female advantage in the cardiovascular risk of hypertensive patients might be attenuated by comorbidities and target organ damage. Another aspect of major clinical importance is whether gender differences exist on the effects of antihypertensive agents in blood pressure reduction and cardiovascular morbidity and mortality. The aim of this review is to critically evaluate recent data regarding gender differences in hypertension and incorporate new data into the body of existing knowledge.

Abstract
Background In general, it is assumed that patient education, by increasing knowledge, may change behavior and lifestyle and promote health. In this context, it is a surprise that knowledge and awareness about blood pressure and hypertension among elderly people is poor. We hypothesized that knowledge about blood pressure and hypertension would be better among individuals with self-reported hypertension compared with subjects without self-reported hypertension. Methods We mailed a questionnaire to a random sample of 1,000 subjects living in the municipality of Silkeborg, Denmark. The study sample was drawn from the Central Person Registry. Results The response rate was 72%. Of these, 43% of responders had self-reported hypertension. The people with self-reported hypertension were older, less educated, had higher self-reported blood cholesterol levels, had higher body weight, and more often had a family history of hypertension. More than 80% reported that overweight and obesity increases blood pressure. More than 60% reported that untreated hypertension may cause heart disease or stroke. More than half of the responders did not know their blood pressure, and only 21% knew that hypertension can occur without symptoms. Knowledge about hypertension was independent of self-reported hypertension status, but awareness about blood pressure was most prominent among those with self-reported hypertension. Conclusion General knowledge about blood pressure and hypertension was reasonable, but there is still room for improvement in elderly people’s knowledge and awareness of blood pressure.

Abstract
INTRODUCTION AND OBJECTIVES The prevalence of resistant hypertension has recently been reported, but there are no studies on its demography. This study aimed to examine the demography and clinical characteristics of resistant hypertension in a large sample of primary care patients. METHODS A cross-sectional study was performed of all computerized medical records of hypertensive patients in Health Area 6 of Madrid (Spain). Of 63 167 hypertensive patients, we selected 48 744 with prescription of antihypertensive medication; of these, we selected those who met the American Heart Association criteria for resistant hypertension. RESULTS A total of 6292 patients had resistant hypertension, representing 9.9% of all hypertensive patients and 12.9% of those treated. A total of 5.5% were < 50 years (8.5% men and 3.2% women) and 24.7% were > 80 years (15.8% men and 31.4% women) (P < .001). In patients < 50 years, resistant hypertension was associated with male sex (odds ratio female/male = 0.006; 95% confidence interval, 0.000-0.042; P < .001), systolic blood pressure, obesity, stroke, and chronic kidney disease (P < .001). In those > 80 years, resistant hypertension was associated with female sex (odds ratio female/male = 1.27; 95% confidence interval, 1.08-1,10; P = .004), systolic blood pressure, diabetes mellitus, obesity, chronic kidney disease, coronary heart disease, and atrial fibrillation (P < .001). More than 50% of patients > 80 years with resistant hypertension had cardiovascular disease. CONCLUSIONS One in 4 patients with resistant hypertension is > 80 years. Resistant hypertension is associated with cardiovascular disease, age < 50 years in men and age > 80 years in women. There is a high proportion of cardiovascular disease in elderly patients with resistant hypertension.

Abstract
Systemic hypertension affects almost a quarter of Canadian adults. Although most can achieve adequate blood pressure control using a combination of medical and lifestyle interventions, many have resistant hypertension and are unable to reach their target. Percutaneous renal sympathetic denervation has been developed to address a crucial mechanism in the pathophysiology of hypertension: renal sympathetic overactivity. In 2009, the first-in-man experience with renal denervation was published. Several studies followed, including the randomized Symplicity HTN-2 trial of 106 patients: 6-month mean blood pressure reduction was 32/12 mm Hg in those who underwent renal denervation, vs a change of +1/0 Hg in those who did not. However, all the evidence to date suffers from the same drawbacks: studies are small, and follow-up is short and largely incomplete. The future of renal denervation will be determined by 3 factors. First, there will be more and better evidence. Symplicity HTN-3 has randomized 530 patients to renal denervation vs a sham procedure; 24-hour ambulatory blood pressure monitoring will be assessed in all participants. Other quality trials will follow, including ones that will assess clinical end points. Second, other indications for this treatment will be investigated. Sympathetic overactivity is implicated in many other conditions, including heart failure and arrhythmia; sympathetic denervation might benefit these patients as well. Third, myriad devices, using different methods to achieve renal denervation, are being developed. The first renal denervation system was approved for clinical use in Canada in March 2012. Until more data are available, patients undergoing this procedure should be carefully screened and, ideally, enrolled in research protocols.

Abstract
BACKGROUND Hospitalizations for ambulatory care sensitive conditions (ACSC) represent an indirect measure of access and quality of community care. This study explored hospitalization rates for 1 ACSC, uncomplicated hypertension, and the factors associated with hospitalization. METHODS A cohort of patients with incident hypertension, and their covariates, was defined using validated case definitions applied to International Classification of Disease administrative health data in 4 Canadian provinces between fiscal years 1997 and 2004. We applied the Canadian Institute for Health Information's case definition to detect all patients who had an ACSC hospitalization for uncomplicated hypertension. We employed logistic regression to assess factors associated with an ACSC hospitalization for uncomplicated hypertension. RESULTS The overall rate of hospitalizations for uncomplicated hypertension in the 4 provinces was 3.7 per 1000 hypertensive patients. The risk-adjusted rate was lowest among those in an urban setting (2.6 per 1000; 95% confidence interval [CI], 2.3-2.7), the highest income quintile (3.4 per 1000; 95% CI, 2.8-4.2), and those with no comorbidities (3.6 per 1000; 95% CI, 3.2-3.9). Overall, Newfoundland had the highest adjusted rate (5.7 per 1000; 95% CI, 4.9-6.7), and British Columbia had the lowest (3.7 per 1000; 95% CI, 3.4-4.2). The adjusted rate declined from 5.9 per 1000 in 1997 to 3.7 per 1000 in 2004. CONCLUSIONS We found that the rate of hospitalizations for uncomplicated hypertension has decreased over time, which might reflect improvements in community care. Geographic variations in the rate of hospitalizations indicate disparity among the provinces and those residing in rural regions.

Abstract
Background Cardiovascular disease (CVD) is one of the leading causes of morbidity and mortality in Vietnam and hypertension (HTN) is an important and prevalent risk factor for CVD in the adult Vietnamese population. Despite an increasing prevalence of HTN in this country, information about the awareness, treatment, and control of HTN is limited. The objectives of this study were to describe the prevalence, awareness, treatment, and control of HTN, and factors associated with these endpoints, in residents of a mountainous province in Vietnam. Methods Data from 2,368 adults (age≥25 years) participating in a population-based survey conducted in 2011 in Thai Nguyen province were analyzed. All eligible participants completed a structured questionnaire and were examined by community health workers using a standardized protocol. Results The overall prevalence of HTN in this population was 23%. Older age, male sex, and being overweight were associated with a higher odds of having HTN, while higher educational level was associated with a lower odds of having HTN. Among those with HTN, only 34% were aware of their condition, 43% of those who were aware they had HTN received treatment and, of these, 39% had their HTN controlled. Conclusions Nearly one in four adults in Thai Nguyen is hypertensive, but far fewer are aware of this condition and even fewer have their blood pressure adequately controlled. Public health strategies increasing awareness of HTN in the community, as well as improvements in the treatment and control of HTN, remain needed to reduce the prevalence of HTN and related morbidity and mortality.

Abstract
Control rates for hypertension have dramatically improved during the past 2 decades-especially in Canada. However, hypertension remains one of the top risk factors for premature death globally. Furthermore, one-third of Canadians with hypertension have not obtained adequate blood pressure control. Most of these patients have resistant hypertension with uncontrolled blood pressure despite therapy. The etiology of resistant hypertension is multifactorial but includes both behavioural and biological factors. Among behavioural factors, nonadherence on the part of patients and especially clinical inertia on the part of health care professionals are contributing causes. An understanding of the root causes underlying the failure to control an individual's blood pressure is central to optimal subsequent management. Further advances in blood pressure control rates in this group of patients will depend on improvements in health care delivery systems and the further development of innovative therapies. Drugs combining multiple antihypertensive agents in a single pill and the development of new technologies to lower blood pressure, primarily by disruption of the sympathetic nervous system, have the potential to be useful strategies in this effort.
