Effects of Intensive Antihypertensive Treatment on Chinese Hypertensive Patients Older Than 70 Years

This study was performed to investigate whether intensive antihypertensive treatment with achieved blood pressure (BP) ≤140/90 mm Hg, as compared with standard treatment with achieved BP ≤150/90 mm Hg, could further improve cardiovascular outcomes in Chinese hypertensive patients older than 70 years. A total of 724 participants were randomly assigned to intensive or standard antihypertensive treatment. After a mean follow‐up of 4 years, the mean achieved BP was 135.7/76.2 mm Hg in the intensive treatment group and 149.7/82.1 mm Hg in the standard treatment group. The visit‐to‐visit variability in systolic BP and diastolic BP was lower in the intensive group than that in the standard group. Intensive antihypertensive treatment, compared with the standard treatment, decreased total and cardiovascular mortality by 41.7% and 50.3%, respectively, and reduced fatal/nonfatal stroke by 42.0% and heart failure death by 62.7%. Cox regression analysis indicated that the mean systolic BP (P=.020; 95% confidence interval, 1.006–1.069) and the standard deviation of systolic BP (P=.033; 95% confidence interval, 1.006–1.151) were risk factors for cardiovascular endpoint events. Intensive antihypertensive treatment with achieved 136/76 mm Hg was beneficial for Chinese hypertensive patients older than 70 years. Long‐term visit‐to‐visit variability in systolic BP was positively associated with the incidence of cardiovascular events.     

Prevalence, awareness, treatment and control of hypertension in Vietnam-results from a national survey

The objective of this study was to estimate mean blood pressure (BP), prevalence of hypertension (defined as BP ≥140/90?mm?Hg) and its awareness, treatment and control in the Vietnamese adult population. This cross-sectional survey took place in eight Vietnamese provinces and cities. Multi-stage stratified sampling was used to select 9832 participants from the general population aged 25 years and over. Trained observers obtained two or three BP measurements from each person, using an automatic sphygmomanometer. Information on socio-geographical factors and anti-hypertensive medications was obtained using a standard questionnaire. The overall prevalence of hypertension was 25.1%, 28.3% in men and 23.1% in women. Among hypertensives, 48.4% were aware of their elevated BP, 29.6% had treatment and 10.7% achieved targeted BP control (<140/90?mm?Hg). Among hypertensive aware, 61.1% had treatment, and among hypertensive treated, 36.3% had well control. Hypertension increased with age in both men and women. The hypertension was significantly higher in urban than in rural areas (32.7 vs 17.3%, P<0.001). Hypertension is a major and increasing public health problem in Vietnam. Prevalence among adults is high, whereas the proportions of hypertensives aware, treated and controlled were unacceptably low. These results imply an urgent need to develop national strategies to improve prevention and control of hypertension in Vietnam.     

The epidemiology of elevated blood pressure as an estimate for hypertension in Aydin, Turkey.

BACKGROUND: Hypertension is an important public health problem, with some variability of its epidemiological properties in different populations. OBJECTIVES: The purpose of this study was to estimate the prevalence of hypertension and to determine the hypertension awareness, treatment and control rates in Aydin, a Turkish province. METHODS: Of 1600 coincidentally selected people aged over 18 years in Aydin, 1480 (92.5%) had their blood pressure (BP) measured and answered a standard questionnaire in 1995. RESULTS: Estimates of the prevalence of hypertension and its control were computed using two different criteria to define hypertension: BP > or =140/90 mm Hg or on treatment and BP > or =160/95 mm Hg or on treatment. Overall, the estimated prevalence of hypertension was 29.6% (for BP > or =140/90 mm Hg or on treatment). Hypertension prevalence increased progressively with age, from 9% in 18- to 29-year-olds to 70.6% in those 70-79 years of age. Women had a significantly higher prevalence than men (34.1% vs 26.0% respectively). Overall, 57.9% of hypertensive individuals were aware that they had high BP, and 82.1% of aware hypertensives were being treated with antihypertensive medications, but only 19.8% of treated hypertensives were under control (systolic pressure <140 mm Hg and diastolic pressure <90 mm Hg). In addition, housewives, unemployed, and the less educated individuals had greater mean systolic and diastolic BP. CONCLUSIONS: Our results indicate that hypertension is highly prevalent in Aydin, Turkey, and the detection and control of hypertension is unsatisfactory.     

The association of nocturnal hypertension and nondipping blood pressure with treatment‐resistant hypertension: The Jackson Heart Study

Apparent treatment‐resistant hypertension (aTRH), nocturnal hypertension, and nondipping blood pressure (BP) have shared risk factors. The authors studied the association between aTRH and nocturnal hypertension and aTRH and nondipping BP among 524 black Jackson Heart Study participants treated for hypertension. Nocturnal hypertension was defined by mean nighttime systolic BP ≥120 mm Hg or diastolic BP ≥70 mm Hg. Nondipping BP was defined by mean nighttime to daytime systolic BP ratio >0.90. aTRH was defined by mean clinic systolic BP ≥140 mm Hg and/or diastolic BP ≥90 mm Hg with three medication classes or treatment with four or more classes. The risk for developing aTRH associated with nondipping BP and nocturnal hypertension was estimated. After multivariable adjustment, participants with aTRH were more likely to have nocturnal hypertension (prevalence ratio, 1.20; 95% confidence interval, 1.03–1.39) and nondipping (prevalence ratio, 1.25; 95% confidence interval, 1.09–1.43). Over a median 7.3 years of follow‐up, nocturnal hypertension and nondipping BP at baseline were not associated with developing aTRH after adjustment.     

Hypertension burden and challenges across the hypertension treatment cascade among adults enrolled in HIV care in northern Tanzania

Failure to address hypertension among people living with HIV (PLWH) may undermine the significant progress made toward reducing mortality among this high‐risk population in sub‐Saharan Africa (SSA). Here, the authors report hypertension prevalence, diagnosis, and treatment among patients enrolled in HIV care in Tanzania. Patients attending an HIV clinic were consecutively screened for hypertension. Hypertension was defined as follows: a single blood pressure measurement ≥160 mm Hg systolic or ≥100 mm Hg diastolic, two measurements at separate visits ≥140 mm Hg systolic or ≥90 mm Hg diastolic, or self‐reported hypertension diagnosis. The authors screened 555 patients, and 19.6% met hypertension criteria. Among a subset of 91 hypertensive participants, 44 (48.4%) reported previous blood pressure measurements, 32 (35.2%) were aware of diagnosis, 10 (11.0%) reported current antihypertensive use, and none had controlled blood pressure. Addressing barriers along the hypertension treatment cascade must be a top priority to improve cardiovascular outcomes among PLWH in SSA.     

Changes in Hypertension Treatment in the Yaroslavl Region of Russia: Improvements Observed Between 2 Cross‐Sectional Surveys

This prospective before‐and‐after survey of hypertensive patients visiting government‐run outpatient health facilities in the Yaroslavl Region of Russia assessed blood pressure (BP)–related endpoints following initiation of a comprehensive health system improvement program for hypertension. Two cross‐sectional surveys, one at baseline and the other approximately 1 year after program initiation, evaluated the primary measure of BP control rate. Secondary measures included mean BP levels and distribution, cardiovascular risk factors, and associated conditions, heart rate levels, and antihypertensive therapy. From the 2011 survey (n=1794) to the 2012 survey (n=2992), BP control rate (<140/90 mm Hg) significantly increased from 16.8% to 23.0%, reflecting a 37% relative improvement (P<.0001). Mean BP level was significantly reduced from 151/90 mm Hg to 147/88 mm Hg (P<.0001). Severe uncontrolled hypertension (systolic BP ≥180 mm Hg) was reduced from 9.7% to 6.4% (P<.0001). Implementing a guidelines‐based treatment protocol with medical and patient education programs resulted in physician behavior change and improved patient BP control.     

Prevalence, awareness, treatment, and risk factors associated with hypertension in the Iranian population: the national survey of risk factors for noncommunicable diseases of Iran

BACKGROUND: The prevalence of hypertension in the Middle East is not well defined. We examined the prevalence, awareness, treatment, and control of hypertension in Iran. METHODS: The Survey of Risk Factors of Noncommunicable Diseases was conducted in 2005 and contains a representative sample of the Iranian adult population. Of 70,981 participants, the data of 68,250 adults aged 25-64 years who had two valid blood pressure (BP) readings were analyzed to estimate the total prevalence of hypertension (systolic BP >or= 140 mm Hg, diastolic BP >or= 90 mm Hg, or the concurrent use of antihypertensive agents) in the Iranian adult population. RESULTS: Approximately 25% or 6.6 million Iranians aged 25-64 years had hypertension; additionally 46% or 12 million Iranians aged 25-64 years had prehypertension. Among hypertensive patients, 34% were aware of their elevated BP; 25% were taking antihypertensive medications; and of these treated subjects, only 24% had BP values <140/90 mm Hg. Hypertension and prehypertension were associated with age, male gender, obesity, central obesity, hypercholesterolemia, and diabetes. CONCLUSIONS: The prevalence of hypertension and prehypertension is high, and the rates of awareness, treatment, and control are unacceptably low. These results underscore the urgent need to develop national strategies to improve prevention, detection, and treatment of hypertension in Iran.     

Characteristics of inner-city African-Americans with uncontrolled hypertension

Hypertension control rates are low in inner-city African-Americans. This article describes the demographic and clinical characteristics of uncontrolled hypertension in this population. During a single outpatient visit, normotensive and hypertensive African-American volunteers (age 18 to 55) completed a questionnaire, and the following measurements were obtained: blood pressure (BP), anthropometric measures, and blood chemistries. Volunteers received a gift for participating. Of the 3,943 volunteers, 52% were hypertensive. Among the hypertensives, 75% were aware of hypertension, and of those aware, 76% were on antihypertensive drug therapy. BP was uncontrolled in 78% of all hypertensives and in 60% of those on drug therapy. Males were two times more likely than females to have uncontrolled hypertension. Compared to participants with controlled hypertension, those with uncontrolled hypertension were younger, had lower body mass index, and were more likely to report smoking cigarettes, drinking alcohol, and less likely to report restricting dietary salt. Lack of hypertension control was primarily related to the lack of antihypertensive drug therapy rather than to inadequate drug therapy. Uncontrolled hypertension was associated with several self-reported aversive health behaviors, including not taking antihypertensive medications. Strategies to improve hypertension control should be directed to patients and to health care providers.     

Independent predictors of effective blood pressure control in patients with hypertension on drug treatment in Brazil

Population assessment of effective blood pressure (BP) control is fundamental for reducing the global burden of hypertension, especially in low‐ and middle‐income countries. The authors evaluated the effectiveness of BP control and determined independent predictors associated with effective control among patients with hypertension on drug treatment in a large cross‐sectional study performed in two metropolitan areas in Brazil's southeast region. A total of 43 647 patients taking antihypertensive treatment were identified. Less than half of the patients (40.9%) had controlled BP (systolic BP <140 mm Hg and diastolic BP <90 mm Hg). Independent predictors of BP control were age, eating fruit daily, physical activity, previous cardiovascular disease, male sex, diabetes mellitus, ethnicity, and obesity. Simple variables associated with BP control may be utilized for knowledge translation strategies aiming to reduce the burden of hypertension.     

Guidelines for management of hypertension: report of the third working party of the British Hypertension Society.

Use non-pharmacological measures in all hypertensive and borderline hypertensive people. Initiate antihypertensive drug therapy in people with sustained systolic blood pressures (BP) >/=160 mm Hg or sustained diastolic BP >/=100 mm Hg. Decide on treatment in people with sustained systolic BP between 140 and 159 mm Hg or sustained diastolic BP between 90 and 99 mm Hg according to the presence or absence of target organ damage, cardiovascular disease or a 10-year coronary heart disease (CHD) risk of >/=15% according to the Joint British Societies CHD risk assessment programme/risk chart. In people with diabetes mellitus, initiate antihypertensive drug therapy if systolic BP is sustained >/=140 mm Hg or diastolic BP is sustained >/=90 mm Hg. In non-diabetic hypertensive people, optimal BP treatment targets are: systolic BP <140 mm Hg and diastolic BP <85 mm Hg. The minimum acceptable level of control (Audit Standard) recommended is <150/<90 mm Hg. Despite best practice, these levels will be difficult to achieve in some hypertensive people. In diabetic hypertensive people, optimal BP targets are; systolic BP <140 mm Hg and diastolic BP <80 mm Hg. The minimum acceptable level of control (Audit Standard) recommended is <140/<90 mm Hg. Despite best practice, these levels will be difficult to achieve in some people with diabetes and hypertension. In the absence of contraindications or compelling indications for other antihypertensive agents, low dose thiazide diuretics or beta-blockers are preferred as first-line therapy for the majority of hypertensive people. In the absence of compelling indications for beta-blockade, diuretics or long acting dihydropyridine calcium antagonists are preferred to beta-blockers in older subjects. Compelling indications and contraindications for all antihypertensive drug classes are specified. For most hypertensives, a combination of antihypertensive drugs will be required to achieve the recommended targets for blood pressure control. Other drugs that reduce cardiovascular risk must also be considered. These include aspirin for secondary prevention of cardiovascular disease, and primary prevention in treated hypertensive subjects over the age of 50 years who have a 10-year CHD risk >/=15% and in whom blood pressure is controlled to the audit standard. In accordance with existing British recommendations, statin therapy is recommended for hypertensive people with a total cholesterol >/=5 mmol/L and established vascular disease, or 10-year CHD risk >/=30% estimated from the Joint British Societies CHD risk chart. Glycaemic control should also be optimised in diabetic subjects. Specific advice is given on the management of hypertension in specific patient groups, ie, the elderly, ethnic subgroups, diabetes mellitus, chronic renal disease and in women (pregnancy, oral contraceptive use and hormone replacement therapy). Suggestions for the implementation and audit of these guidelines in primary care are provided.     

Metabolic syndrome and masked hypertension among African Americans: The Jackson Heart Study

The metabolic syndrome is associated with higher ambulatory blood pressure. The authors studied the association of metabolic syndrome and masked hypertension (MHT) among African Americans with clinic‐measured systolic/diastolic blood pressure (SBP/DBP) <140/90 mm Hg in the Jackson Heart Study. MHT was defined as daytime, nighttime, or 24‐hour hypertension on ambulatory blood pressure monitoring. Among 359 participants not taking antihypertensive medication, the metabolic syndrome was associated with MHT (prevalence ratio, 1.38; 95% confidence interval, 1.10–1.74]). When metabolic syndrome components (clinic SBP/DBP 130–139/85–89 mm Hg, abdominal obesity, impaired glucose, low high‐density lipoprotein cholesterol, high triglycerides) were analyzed separately, only clinic SBP/DBP 130–139/85–89 mm Hg was associated with MHT (prevalence ratio, 1.90; 95% confidence interval, 1.56–2.32]). The metabolic syndrome was not associated with MHT among participants not taking antihypertensive medication with SBP/DBP 130–139/85–89 and <130/85 mm Hg, separately, or among participants taking antihypertensive medication (n=393). Ambulatory blood pressure monitoring screening for MHT among African Americans should be considered based on clinic BP, not metabolic syndrome.     

Prevalence and therapeutic control of hypertension in 30,000 subjects in the workplace

-To assess blood pressure (BP) control in a French working population through the use of a careful assessment of BP based on 2 different visits in 1 month, 17 359 men and 12 267 women were evaluated from January 1997 to April 1998. The initial phase was a cross-sectional analysis of a cohort study designed to assess the incidence of arterial hypertension in a French working population. Information was collected by the work-site physician during the annual examination. BP was measured with a validated automatic device. Among subjects with BP >/= mm Hg, patients not treated with antihypertensive drugs were invited to have an additional BP measurement taken 1 month later. The prevalence of hypertension (BP >/= mm Hg) based on 2 visits was 16.2% in men and 9.4% in women. When the diagnosis of hypertension was based on 2 visits, its prevalence was 41% lower in men and 36% lower in women compared with that of a diagnosis based on a single visit. Accordingly, the awareness of hypertension was 49% higher in men and 40% higher in women. Overall, 12.5% of hypertensive men and 33.2% of hypertensive women taking antihypertensive medication had their BP levels lowered to < mm Hg by treatment. Although the percentage of hypertensive men and women under current treatment who were aware of their hypertension increased with age, BP control among treated subjects decreased with age. Ineffective BP control with treatment accounted for 33% of BP levels >/= mm Hg in men and 40% of those observed in women. In this large French working population, estimates of hypertension therapeutic control depend heavily on the number of BP measurements. Despite these methodological precautions, insufficient awareness of BP and insufficient BP control through treatment remain 2 major public health problems.     

Prevalence, Treatment, and Control of Hypertension in the French Population: Data From a Survey on High Blood Pressure in General Practice, 1994

A survey was conducted in a cohort of 235 general practitioners (GP) selected by Sofres Médical who were representative of the French medical population, to measure the percentage of patients with hypertension, treated hypertensives and patients with controlled hypertension. Data were collected over 1 week of office consultation. Practitioners were initially instructed to use the same type of mercury sphygmomanometer, equipped with pneumatic cuffs of different sizes. Three consecutive blood pressure (BP) measurements were made and the last two were recorded. Practitioners had to carry out their own survey over a period of 1 week on all patients > 18 years of age who visited their offices. Patients were considered as hypertensive (HP) if the mean of the two recorded BP measurements was ≥ 140/90 mm Hg or if they were taking antihypertensive drug treatment. Three cutoff points were used to define controlled hypertension: < 140/90 mm Hg (overall population of HP), < 160/95 mm Hg (HP < 65 years of age), and < 160/90 mm Hg (HP ≥ 65 years of age).Among 12,351 patients (mean age, 48.6 years; women, 58%), 5020 were HP, (41%) of whom 2035 were without treatment (41%) and 2985 were receiving antihypertensive drug treatment (59%).Two hundred-thirty patients (4.6%) remained at high risk with moderate or severe hypertension (BP ≥ 180 [systolic] or 105 [diastolic] mm Hg), ie, 1 patient/week/GP.The study confirms the high prevalence of hypertension in general practice and shows that 7 of 10 patients have an acceptable control of their BP (< 160/95 or < 160/90 mm Hg according to age) but only 24% of treated HP achieved the target of a BP level < 140/90 mm Hg, representing 28% of the 18 to 64 year old group and 21% of the elderly group.French GP did not choose an optimal control, and the medical community is waiting for answers to crucial questions, ie, does optimal BP control significantly improve the absolute cardiovascular risk? How far should blood pressure be lowered?     

Untreated,Uncontrolled, and Apparent Resistant Hypertension: Results of the German Health Examination Survey 2008–2011

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.     

Blood pressure in relation to frailty in older adults: A population‐based study

In frail older adults, low blood pressure (BP) might be associated with worse health outcomes and hypertension management in this population is highly debated. Using data from a population‐based study of older adults, we assessed the association between frailty and BP. We used data collected between 2014 and 2016 from 3157 participants aged between 67 and 80 years in the Lausanne cohort Lc65+. BP was measured three times at one visit, and frailty status was assessed based on Fried's phenotype model. We analyzed the cross‐sectional association between BP and frailty by computing mean systolic and diastolic BP stratified by sex, age, and frailty and by fitting regression models. The average age of the participants was 73.3 (standard deviation [SD]: 4.1) years, and 59.1% were women. 34.1% were pre‐frail, and 3.3% were frail. Mean BP was 135.1/76.3 mm Hg (SD 18.5/11.0). Age‐ and sex‐adjusted systolic BP was on average lower by 2.8 mm Hg (95% confidence interval [CI]: 1.4‐4.2) and 6.7 mm Hg (95% CI: 3.2‐10.3) among pre‐frail and frail compared to non‐frail participants. Similar differences in mean diastolic BP across frailty status were found. Upon adjustment for antihypertensive treatment, the associations between frailty status and BP did not change substantially. Frail individuals had a substantially lower BP compared with non‐frail older adults. Because low BP could be detrimental among frail older patients, our findings raise questions about hypertension management in this population and stress the need for additional evidence.     

Barriers to blood pressure control in China in a large opportunistic screening

We investigated the prevalence, awareness, treatment, and control of hypertension in a large opportunistic screening study in China. Our study participants had to be ≥18 years of age and had ideally not taken blood pressure (BP) for ≥1 year. BP was measured three times consecutively in the sitting position with a 1‐minute interval, using a validated electronic BP monitor or mercury sphygmomanometer. Trained volunteer investigators administered a questionnaire to collect information on medical history, lifestyle, and use of medications. The 364 000 participants (52.6% women, and mean age 53.4 years) had a mean systolic/diastolic BP of 124.2/76.4 mm Hg. The proportion of hypertension was 24.7%. In all hypertensive subjects (n = 89 925), the awareness, treatment, and control rates of hypertension were 60.1%, 42.5%, and 25.4%, respectively. In multiple stepwise logistic regression analyses, the odds for unawareness vs awareness of hypertension was higher in men and lower with age advancing, current smoking, and the presence of diabetes mellitus, coronary heart disease, and stroke or transient ischemic attack (P < .0001). The odds for uncontrolled vs controlled hypertension was higher with age advancing and current smoking, and lower with the presence of diabetes mellitus and coronary heart disease (P ≤ .03) in 38 207 treated hypertensive patients, and it was also higher with the use of antihypertensive monotherapy (odds ratio 1.13, P = .0003) in 19 523 treated hypertensive patients with specific antihypertensive drugs. Our study identified several factors as barriers to BP control in China, such as male gender, younger age, current smoking, and the under‐use of combination therapy.     

Trend of Blood Pressure Control Status in Hypertensive Outpatients: With Special Reference to Elderly Hypertensives

Blood pressure (BP) control in hypertensives has improved; however, it still remains to be insufficient. We have investigated the trend in BP control status of the hypertensive patients followed for 10 years in hypertension clinic. Subjects included 133 patients who have been followed from the first visit during 1998–2000 to the last visit during 2008–2010. During the mean follow-up period of 10.5 years, average BP and body weight significantly (P < .01) decreased from 143 ± 12/85 ± 8 mm Hg to 129 ± 14/68 ± 11 mm Hg, and from 59.8 ± 9.9 kg to 58.7 ± 10.6 kg, respectively. The achievement rate of good BP control defined as <140/90 mm Hg and the number of antihypertensive drugs also increased significantly during this period (39.1%–77.5% and 1.3 ± 1.0–2.2 ± 1.1, respectively, P < .01). Blood pressure control improved and the number of antihypertensive drugs also increased in 45 patients who were older than 65 years at the last visit. The use of Ca channel blockers (CCBs), angiotensin II receptor antagonists, and diuretics increased significantly during this period. Results suggest that lifestyle modification including body weight reduction as well as intensive antihypertensive treatment contributed to the improved BP control in hypertensive patients including the elderly.     

Resistant Hypertension: Risk Factors,Subclinical Atherosclerosis,and Comorbidities Among Adults—The Brazilian Longitudinal Study of Adult Health (ELSA‐Brasil)

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 m²), 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.     

Prevalence,awareness, treatment,and control of hypertension in Greece: The Didima study

To assess the prevalence and the levels of awareness, treatment, and control of hypertension in the rural population of Greece, a cross-sectional survey of the total population age ≥18 years of the village Didima was conducted. The survey included an interview and blood pressure (BP) measurement on two clinic visits. Hypertension was defined as systolic BP ≥ 140 mm Hg and or diastolic BP ≥ 90 mm Hg or current treatment with antihypertensive drugs. The same BP threshold was used for the assessment of hypertension control.A total of 694 inhabitants participated (response rate 76.4%), and 665 were analyzed. The prevalence of hypertension was 28.4% (men 30.2%, women 27.1%). Of the subjects age ≥65 years, 50% had hypertension. Although 73% of participants were measuring their BP at least once a year, overall, 39.2% of hypertensives were unaware of the diagnosis (men 50%, women 30.5%), 6.3% were aware but not treated (men 4.8%, women 7.6%), 27.5% were treated but not controlled (men 22.6%, women 31.4%), and 27% were treated and controlled (men 22.6%, women 30.5%). These results suggest that, in the rural population of Greece, hypertension is a common risk factor with considerable potential for improvement in levels of control.     

Comparison of day‐to‐day blood pressure variability in hypertensive patients with type 2 diabetes mellitus to those without diabetes: Asia BP@Home Study

Blood pressure variability (BPV) has been shown to be independently associated with cardiovascular (CV) mortality and morbidity. Patients with type 2 diabetes mellitus (T2DM) have also been shown to have increased BPV. We aimed to compare BPV in hypertensive patients with diabetes with those without diabetes. A total of 1443 hypertensive patients measured their blood pressure (BP) twice in the morning and twice before bed at home for a week. Demographic data, history of T2DM, and anti‐hypertensive use were captured. Clinic BP was measured twice in the clinic. Control of BP was defined as clinic systolic BP (SBP) <140 mm Hg and home SBP < 135 mm Hg. BPV was based on home SBP measurements. A total of 362(25.1%) hypertensives had diabetes and 47.4% were male. Mean age was 62.3 ± 12.1 years. There was no difference in the mean clinic SBP in both groups (139.9 mm Hg vs 138.4 mm Hg P = .188). However, the mean morning home SBP was significantly higher and control rate lower in hypertensives with diabetes than those without (132.3 ± 15 mm Hg vs 129.7 ± 14.4 mm Hg P = .005, 39.4% vs 47.6% P = .007), respectively. Masked uncontrolled morning hypertension was higher in those with diabetes versus those without (12.8% vs 8.4%, respectively). There was no statistically significant difference in BPV between those with and without diabetes. In summary, clinic SBP was similar in hypertensives with or without diabetes. However, control of BP based on both clinic and home SBP thresholds was poorer in hypertensives with diabetes compared to those without. Masked uncontrolled morning hypertension was higher in those with diabetes than those without. There was no difference in BPV between the two groups.
