Abstract
In metropolitan France, estimates suggest that more than one in three adults has hypertension. Low-cost treatments are available, yet fewer than one in four hypertensive adults has a controlled level of hypertension below 140/90 mmHg. This rate is higher in other high-income countries such as Canada (65%) or Germany (52%). Using a 'cascade of care' model, that decomposes the hypertension care continuum in awareness, treatment, and control, provides a better understanding of the origins of poor control. Furthermore, the theoretical framework of intersectionality, which simultaneously considers social positions of gender, class, and ethno-racial origin, could be used to understand the complexity of the social inequalities observed in hypertension-related outcomes. In this article we conducted a critical review of the international literature to identify new lines of analyses that could be applied to examine complex inequalities in France.

Abstract
Many studies document significant causal impacts of retirement on cognitive abilities. It remains unclear if cognitive functioning could be hindered in post-retirement due to heightened physiological responses to stress. Using repeated observations of biomarkers, retirement status, and the word-recall test score from the Health and Retirement Study (n = 25,367; 15,343 among women and 10,024 among men), the study tests this pathway, separately for men and women. The study employs the two-stage least squares fixed-effects model that simultaneously fits three equations predicting the total-recall score, cardio-metabolic risk index, and retirement status. Being retired for at least a year decreases cardio-metabolic risk for men and women, and the resulting relief of cardio-metabolic risk improves cognitive functioning for women but not for men. Retirement does not lead to a downward health spiral as previously suggested; rather, it provides a much needed relief from stressors for those who are at health risks.

Abstract
PURPOSE To compare differences in prevalence rates, treatment and control of hypertension (AHT) between males and females in general medicine consultation in the area of Blida (Algeria). METHODS We included 3622 patients in the study (42% males and 58% females), with a mean age of 48.14±10.11 years, examined between January 2014 and June 2016 in general medicine consultation in the area of Blida (Algeria). Data was collected with individual questionnaires. Measurement of blood pressure was made using validated semi-automatic devices (OMRON HEM model 705CP). Individuals using antihypertensive drugs and/or blood pressure (BP) greater than or equal to 140/90mmHg were considered as hypertensives. The knowledge about the disease was identified among those who claimed to be aware of the diagnosis before the measurements. The treatment rate was calculated with those who reported using antihypertensive drugs. Controlled blood pressure was considered in individuals with values lower than 140/90mmHg. Lipid profile (total cholesterol, triglycerides, HDL and LDL cholesterol), and fasting blood sugar were measured. All calculations and statistical analyses are processed by the SPSS 20.0. RESULTS The prevalence of hypertension was higher among men (46.2%) than women (31.6%) (P<0.001), and among aged over 55 years (P< 0.05) and those that have referred hypertensive parents (P<0.05). Among hypertensive men, 55.7% knew the diagnosis, 63.6% of them were under treatment, and 22% had controlled BP. Among the hypertensive women 69.8% knew the diagnosis, 85.1% were under treatment and 35.6% were with controlled BP (P<0.001 for the three variables). The most frequent associated risk factors were diabetes mellitus in 36.8% of the patients, obesity in 35.7% of the patients, microalbuminuria in 23.6% of the patients, hypercholesterolemia>2g/L in 11.6% of the patients, smoking in 7.7% of them. Presence of controlled AHT was not found to be associated with presence of other risk factors. The likelihood of having AHT was higher among men, diabetics, older subjects and higher BMI. CONCLUSION Our study confirmed the high prevalence of AHT in general medicine consultation in Blida, which is a representative city in the north of Algeria. Although women are better treated, much remains to be done to reach BP goal, much in our countries which have the least financial resources to combat cardiovascular disabilities.

Abstract
OBJECTIVE The main objective of this study was to assess the effects of pharmaceutical care interventions in patients with essential hypertension in Lakshmi Pat Singhania Institute of Cardiology, Kanpur, India. METHODS The study was carried out from July 2010 to August 2011. Pharmaceutical care was provided for 54 patients (intervention group) which was comprised of the patient education, the prescription assistance and the life style modifications and motivation for health. Then the clinical outcome as well as health related quality of life (HRQOL) were compared with the control group (48 patients) in which the pharmaceutical care was not provided. Furthermore, the effect of pharmaceutical care intervention on HRQOL was assessed using Short Form-36 (SF-36), a general health related quality of life questionnaire used to evaluate the QOL of patients. Blood pressure (BP) measurements and QOL survey was performed at baseline and at the follow-up session. FINDINGS The difference between blood pressure readings from the baseline to the second follow-up was significant for systolic [(P = 0.0001), 12.24 mmHg] and diastolic BP [(P = 0.001), 5.17 mmHg] in the intervention group. The questionnaire used to evaluate the QOL of patients also showed improvement in the mean score for intervention group. CONCLUSION Results from our study showed that applying pharmaceutical care to hypertensive patients can help in the control of these patients' blood pressure, and consequently lower the risk that hypertension poses in cardiovascular disease. Successful implementation of pharmaceutical care has the potential to increase patients' satisfaction with their pharmacists' activities and may increase patients' expectations that pharmacists will work on their behalf to assist them with their healthcare needs.

Abstract
BACKGROUND The rate of uncontrolled hypertensives aged >80 years is not well known. The available literature on this topic has used the threshold <140/90 mmHg, whereas there is now a consensus for a different target: systolic blood pressure (SBP)<150 mmHg. AIMS This prospective observational population-based study sought to assess the frequency and management of uncontrolled hypertension in French patients aged ≥80 years. METHODS Nine hundred and seventy-one treated hypertensive outpatients were evaluable (204 recruited by cardiologists, 767 by general practitioners [GPs]; mean age 84.8 ± 3.8 years; 57.8% women). RESULTS The frequency of SBP ≥ 150 mmHg was 36.6% (44.6% in cardiologists' patients and 34.4% in GPs' patients). The frequency of satisfaction with SBP ≥ 150 mmHg was 22.0% for cardiologists (32.6% if diastolic blood pressure [DBP] <90 mmHg and 9.5% if ≥90 mmHg; P=0.008) and 30.4% for GPs (51.7% if DBP <90 mmHg and 13.2% if ≥90 mmHg; P<0.0001). Non-diabetic status (for cardiologists) and DBP <90 mmHg (for cardiologists and GPs) were independent determinants of SBP being considered acceptable. Accordingly, in patients with an SBP level ≥ 150 mmHg that was considered too high, treatment was reinforced more often if DBP was ≥90 mmHg (82.3%) than <90 mmHg (68.5%). CONCLUSION In France, hypertension is uncontrolled in more than one in three elderly hypertensives. Physicians are aware that SBP should be lowered to <150 mmHg in patients aged>80 years, but when the target is not reached they are less likely to increase treatment if DBP is <90 mmHg.

Abstract
OBJECTIVES The Arterial High blood pressure represents a consultation on 5 in general medicine. The main objective of our study was to estimate patients' proportion appearing at emergency department (ED) with a high Blood pressure and to demonstrate that it is possible to detect the patients at risk of essential and secondary hypertension as well as their cardiovascular risk there. METHODS Non-interventional forward-looking Study led over 6 weeks. After measure of the vital parameters in the reception of ED, the patients were included if the Systolic Blood Pressure (SBP) was ≥ 140 mmHg and\or Diastolic Blood Pressure (DBP) ≥ 90 mmHg. A control of Blood Pressure (BP) was made at least 40 minutes after the inclusion. If the Arterial High blood pressure persisted (BP ≥ 140/90 mmHg and age < 30 years or BP ≥ 180/110 mmHg after 30 years), the patients had to see again a cardiologist of the hospital in 7 days because they were considered as at high cardiovascular risk. RESULTS A high initial BP was discovered to 582 (8,7 %) 6685 patients having consulted in ED during the period of the study. 64 % of them (n = 372) had a persistent Arterial High Blood pressure after 40 minutes. 27 patients, defined at high cardiovascular risk had a proposition of consultation of cardiology, appeared 11 to it. 4 secondary hypertension was discovered. CONCLUSION During the period of study, 582 patients presented a High BP. To 64 % of those who had a control of BP this imbalance was confirmed. The patients (n=27) presenting a high cardiovascular risk had a proposition of fast consultation. This one allowed discovering 4 secondary hypertension. There is thus a utility to estimate the BP in a systematic way at Emergency Department.

Abstract
The authors review the present situation in epidemiology and prevention of arterial hypertension in Poland. In 2002, the NATPOL PLUS survey on representative sample of adults (n=3051, age range 18-93) was conducted. Prevalence of hypertension, diagnosed on basis of three separate visits, was 29%, awareness 67% and efficacy of treatment 12.5%. Thus, in Poland, one-third of 8.6 million hypertensives are unaware of their disease. A comparison with data from other countries should be careful due to the different methods (age range, number of readings and visits) used in the studies. The data, in concert with a decrease in awareness of one's own blood pressure (from 71% in 1994 to 59% in 2002), called for urgent preventive measures. Two large interventions were implemented under the National Programme POLKARD in 2003: the Polish 400 Cities Project aimed to increase detection and knowledge of hypertension and other risk factors among small-town and village communities, and the educational project, A Chance for the Young Heart targeted at children aged 11-14 years and using traditional teaching methods and an interactive Internet website. Also, an educational and marketing programme targeted at public opinion leaders and decision makers (trade unions, local governments, healthcare financing authorities, print media and radio, the Polish Parliament) started in 1999 and is still in process.

Abstract
BACKGROUND Arterial hypertension is managed mainly by general practitioners. The blood pressure level of most patients treated in a general practice setting is greater than or equal to 140/90 mmHg. AIMS To understand why a blood pressure level greater than or equal to 140/90 mmHg does not lead to a change of treatment. METHODS Over a 2-week period, 479 hypertensive patients were included in a cross-sectional study by 27 general practitioners. Consultation data were collected, as were reasons why patients with a blood pressure level greater than or equal to 140/90 mmHg did not have their treatment changed. RESULTS Blood pressure level was greater than or equal to 140/90 mmHg in 58% of patients; treatment was changed in 15% of these individuals. The lack of change in treatment was justified by the physicians as follows: the blood pressure measurements were not considered to be representative (about 30% of cases); the therapeutic result was considered to be satisfactory in the circumstances (about 30% of cases); change was not appropriate given the patient's specific context (the remaining third of cases). The proportion of uncontrolled hypertensive patients whose treatment remained the same was significantly higher among patients with a disease that affected their lifestyle or threatened their life expectancy. CONCLUSION The disappointing therapeutic results observed in the management of arterial hypertension do not arise only from poor application of guidelines by general practitioners. Reluctance to rely on blood pressure measurements, a perception that guidelines are revised frequently and are not always clear, and consideration of the general practitioner's activity in the patient's specific context are the main factors involved.

Abstract
INTRODUCTION Sleep is an innate and essential part of human life. Various aspects of sleep are negatively affected by beta-blockers. We compared the impact of two beta-blockers, metoprolol succinate (extended release) and nebivolol, on sleep quality in patients with stage 1 hypertension. METHODS This was a prospective, randomized, open-label, parallel-group study. Eligible patients were administered the Pittsburgh Sleep Quality Index (PSQI) questionnaire by a blinded interviewer and were randomized to receive metoprolol (starting dose 25 mg) or nebivolol (starting dose 2.5 mg) once daily for 6 weeks. The first dose was administered before patients left the clinic. Visits were scheduled for 1, 2, 4, and 6 weeks after the initiation of therapy. At the end of the study, patients were readministered the PSQI questionnaire by the same interviewer, as before blinded to treatment allocation. RESULTS A total of 22 patients in the nebivolol group and 17 patients in the metoprolol group completed the study and were included in the data analysis (mean age of patients, 40.7 years). At study entry, systolic blood pressure (BP), diastolic BP, and PSQI scores were similar in the two groups. Over 6 weeks of treatment, systolic and diastolic BP normalized in both groups. Global PSQI score improved significantly in patients in the nebivolol group, whereas it worsened in the metoprolol group. The difference in effect of two beta-blockers was statistically significant (P<0.001). CONCLUSION Nebivolol was associated with improved sleep (as assessed by the PSQI), whereas metoprolol was associated with a worsening of sleep characteristics.

Abstract
AIM To evaluate the prevalence, awareness, treatment and control of hypertension in a diabetic population of Cameroon, a sub-Saharan African country. METHODS Two hundreds and ten diabetic patients were consecutively enrolled over a 6-month period. A questionnaire was administered and physical examination done. The JNC VI and the latest WHO criteria were used to diagnose hypertension and diabetes, respectively, and control of hypertension was assessed against five different targets. RESULTS Ninety-one percent of the participants had type 2 diabetes. Prevalence and awareness rates for hypertension were 66.7% (n=140) and 87.1% (n=122), respectively. Treatment rate among those aware of their hypertension status was 80.3% (n=98). Patients with hypertension were older, more overweight/obese and had a longer duration of diabetes. ACE inhibitors and diuretics were the two most used blood pressure (BP) lowering drugs. Following the ADA/JNC 7 goal, the control rate of hypertension among treated patients was 10.2% (n=10). CONCLUSION Diabetic patients in Cameroon exhibit a very high prevalence of hypertension and are about three times more affected than the general population. Awareness and treatment rates are high, but the control rate is very low. Large scale studies with intervention component are urgently required.

Abstract
OBJECTIVE Assessment of total cardiovascular risk level is crucial for approaching hypertensive patients. Therefore, the aim of the Intensive/Initial Cardiovascular Examination regarding Blood pressure levels: Evaluation of Risk Groups (ICEBERG) study is to determine cardiovascular risk evaluation and stratification of subjects with high normal and high blood pressure (BP > or = 130/85 mmHg), and to evaluate the impact of laboratory tests on this stratification. METHODS ICEBERG was an epidemiological study conducted at 20 university hospitals and 197 primary healthcare centers. A total of 10,313 patients, who were diagnosed with high BP and under antihypertensive treatment or not antihypertensive under treatment at least for the last 3 months were selected. Besides routine clinical evaluation, microalbuminuria (MAU) and high sensitive C-reactive protein (hs-CRP) tests, echocardiography (Echo) and carotid ultrasonography (USG) were performed in selected arms. The patients were stratified into low, moderate, high and very high added risk groups as described by the European Society of Hypertension/European Society of Cardiology Guidelines Committee (2003). RESULTS Upon routine evaluation, the percentage of "high and very high added cardiovascular risk" groups was between 51.2% and 60.7% in different study arms. This percentage increased to 62.9% by subsequent serum biochemistry assessment and to 76.2% by hs-CRP test results. Switching upwards to "high and very high added risk" groups was around 6% when MAU results were used, with a 4.9% upwards switch to "high and very high added risk" groups when Echo was performed; this proportion increased by 6.8%, when carotid USG was taken into account. CONCLUSION Cardiovascular risk evaluation by intensive cardiovascular examination including Echo and carotid USG provided more accurate risk stratification. Furthermore, a simple test to demonstrate presence of MAU usable at primary healthcare level will also help to evaluate the patient's risk profile better than routine assessment methods alone.

Abstract
There is growing evidence that nitric oxide (NO)-mediated endothelial dysfunction occurs in hypertension and may represent the earliest stage of target organ damage, which ultimately leads to hypertensive heart disease and heart failure (HF). An understanding of how impaired myocardial microvascular function and flow reserve relate to early remodeling during the transition to HF in patients with hypertension may lead to new therapeutic insights. The hypertrophied heart, which is a feature of the adverse structural remodeling in hypertensive heart disease, may be accompanied by impaired coronary flow reserve (CFR). Reduced CFR could potentially cause subendocardial ischemia during conditions of high metabolic demand, such as uncontrolled hypertension and tachycardia. Such vulnerability of the subendocardium to abnormal perfusion or ischemia may accelerate the progression from compensated hypertrophy to HF. In this review, we discuss preliminary evidence that altered NO balance may contribute to cardiac hypertrophy-mediated myocardial ischemia. We also describe early results with myocardial contrast echocardiography in the postulated transition from compensated hypertrophy to cardiac failure. These data support further evaluation of NO mediators as potential targets for novel therapies in hypertensive heart disease.

Abstract
Nebivolol is a novel beta1-blocker with a greater degree of selectivity for beta1-adrenergic receptors than other agents in this class and a nitric oxide (NO)-potentiating, vasodilatory effect that is unique among beta-blockers currently available to clinicians (nebivolol is approved in Europe and is currently under review in the US). A NO-potentiating agent such as nebivolol may have an important role in hypertensive populations with reduced endothelial function such as diabetics, African-Americans and those with vascular disease. Nebivolol is a racemic mixture with beta-blocker activity residing in the d-isomer; in contrast, l-nebivolol is far more potent in facilitating NO release. Nebivolol is unique among beta-blockers in that, at doses <10 mg, it does not inhibit the increase in heart rate normally seen with exercise. The efficacy of nebivolol has been tested successfully in clinical trials against other agents including other beta-blockers, angiotensin-converting enzyme-inhibitors and calcium channel antagonists in patients with hypertension, angina, and congestive heart failure. The tolerability of nebivolol has been shown to be superior to that of atenolol and metoprolol. In controlled clinical trials, nebivolol has a side effect profile that is similar to placebo, in particular as it relates to fatigue and sexual dysfunction. This article will review published clinical data regarding this cardioselective beta-blocker.

Abstract
Despite progress in recent years in the prevention, detection, and treatment of high blood pressure (BP), hypertension remains an important public health challenge. Hypertension affects approximately 1 billion individuals worldwide. High BP is associated with an increased risk of mortality and morbidity from stroke, coronary heart disease, congestive heart failure, and end-stage renal disease; it also has a negative impact on the quality of life. Hypertension cannot be eliminated because there are no vaccines to prevent the development of hypertension, but, its incidence can be decreased by reducing the risk factors for its development, which include obesity, high dietary intake of fat and sodium and low intake of potassium, physical inactivity, smoking, and excessive alcohol intake. For established hypertension, efforts are to be directed to control BP by lifestyle modification (LSM). However, if BP cannot be adequately controlled with LSM, then pharmacotherapy can be instituted along with LSM. Normalization of BP reduces cardiovascular risk (for cardiovascular death, myocardial infarction, and cardiac arrest), provides renoprotection (prevention of the onset or slowing of proteinuria and progression of renal dysfunction to end-stage renal disease in patients with hypertension, diabetes mellitus types 1 and 2, and chronic renal disease), and decreases the risk of cerebrovascular events (stroke and cognition impairment), as has been amply demonstrated by a large number of randomized clinical trials. In spite of the availability of more than 75 antihypertensive agents in 9 classes, BP control in the general population is at best inadequate. Therefore, antihypertensive therapy in the future or near future should be directed toward improving BP control in treated hypertensive patients with the available drugs by using the right combinations at optimum doses, individually tailored gene-polymorphism directed therapy, or development of new modalities such as gene therapy and vaccines. Several studies have shown that BP can be reduced by lifestyle/behavior modification. Although, the reductions appear to be trivial, even small reductions in systolic BP (for example, 3-5 mm Hg) produce dramatic reduction in adverse cardiac events and stroke. On the basis of the results of clinical and clinical/observational studies, it has been recommended that more emphasis be placed on lifestyle/behavior modification (obesity, high dietary intake of fat and sodium, physical inactivity, smoking, excessive alcohol intake, low dietary potassium intake) to control BP and also to improve the efficacy of pharmacologic treatment of high BP. New classes of antihypertensive drugs and new compounds in the established drug classes are likely to widen the armamentarium available to combat hypertension. These include the aldosterone receptor blockers, vasodilator beta-blockers, renin inhibitors, endothelin receptor antagonists, and dual endopeptidase inhibitors. The use of fixed-dose combination drug therapy is likely to increase. There is a conceptual possibility that gene therapy may yield long-lasting antihypertensive effects by influencing the genes associated with hypertension. But, the treatment of human essential hypertension requires sustained over-expression of genes. Some of the challenging tasks for successful gene therapy that need to be mastered include identification of target genes, ideal gene transfer vector, precise delivery of genes into the required site (target), efficient transfer of genes into the cells of the target, and prompt assessment of gene expression over time. Targeting the RAS by antisense gene therapy appears to be a viable strategy for the long-term control of hypertension. Several problems that are encountered in the delivery of gene therapy include 1) low efficiency for gene transfer into vascular cells; 2) a lack of selectivity; 3) problem in determining how to prolong and control transgene expression or antisense inhibition; and 4) difficulty in minimizing the adverse effects of viral or nonviral vectors. In spite of the hurdles that face gene therapy administration in humans, studies in animals indicate that gene therapy may be feasible in treating human hypertension, albeit not in the near future. DNA testing for genetic polymorphism and determining the genotype of a patient may predict response to a certain class of antihypertensive agent and thus optimize therapy in individual patients. In this regard, there are some studies that report the effectiveness of antihypertensive therapy based upon the genotype of selected patients. Treatment of human hypertension with vaccines is feasible but is not likely to be available in the near future.

Abstract
OBJECTIVES The prescribing pattern of drugs used for treating hypertension changes over time in response to changes in recommended guidelines and innovations in drug formulations, among others. In addition, the classes of antihypertensive drugs used vary among the countries. The aim of this study was to investigate the practice of antihypertensive medications in primary care units in Turkey. METHOD TURKSAHA is a cross-sectional screening study conducted in 1000 primary care units considered to be representative of primary care in Turkey, with the purpose of defining the demographic characteristics, clinical features, rate of blood pressure control achieved and the antihypertensive drugs prescribed for the hypertensive patients treated in these centers. In this analysis, we investigated the agents used in the treatment regimen. RESULTS Of the 16,270 patients considered to be eligible for inclusion in the study, 15,187 (93.3%) were on an antihypertensive treatment, and 1083 (6.7%) were receiving no treatment. Patients who received treatment but whose antihypertensive medication was not specified (2290 patients) were subsequently excluded, and the trial was carried out with the remaining 12,897 patients. The mean age of the patients was 60 +/- 11 years (60.2% female). Of the 12,897 patients, 75.7% were receiving monotherapy, 19.7% two drugs, 4.1% three drugs and 0.5% four or more drugs. The rate of successful blood pressure control (<140/90 mmHg; for diabetics <130/80 mm Hg) in relation to the number of drugs received was 26.3, 25.9, 24.5 and 26.2%, respectively. Among the patients receiving monotherapy, the most frequently used antihypertensive drug class was angiotensin-converting enzyme inhibitors (30.1%), followed by beta-blockers (20.6%), calcium-channel blockers (17.9%), diuretics (15.4%) and angiotensin-receptor blockers (14%). CONCLUSION As in other European countries, the rate of successful blood pressure control was low among hypertensive patients receiving treatment, and despite the inadequacy of monotherapy to control blood pressure, many of the patients continued this treatment regimen. Consistent with the global trend, the most frequently prescribed anti-hypertensives were angiotensin blockers.

Abstract
Although the management and the control rates of hypertension are generally low throughout the world, there are substantial differences between the countries. The aim of this study was to determine the control rate of blood pressure and the characteristics of the patients who have been admitted to primary care units in Turkey. Our study included 16,270 patients aged above 18 years who were diagnosed as hypertensive in representative nationwide sample of 1,000 primary care units in Turkey. The mean age of the patients was 60+/-11 years (60.1% women). Of 16,270 patients, 15 187 (93.3%) were on an antihypertensive treatment, whereas 1,083 (6.7%) were receiving no treatment. The patients who were women, diabetic, smoker, obese, and those who had a concomitant cardiovascular disease (CVD) had a higher rate of antihypertensive treatment. Of 15,187 treated patients, 4,912 (30.2%) had a controlled systolic blood pressure, 7,063 (43.4%) a controlled diastolic blood pressure, and in 3,931 (24.2%), both were under control. A logistic regression analysis demonstrated that age (OR 1.33), diabetes (OR 4.96), body mass index (OR 1.41) and the presence of a CVD (OR 1.19) were predictors for blood pressure being under control. The blood pressure control rates ranged between 16.6 and 30.5% among seven geographical regions. In the primary care units in Turkey, the blood pressure control rate is consistently low in treated hypertensive patients. In addition, there are differences between the geographical regions in both the proportion of those receiving medications and the blood pressure control rates.

Abstract
BACKGROUND The aim of the SMOOTH (San Marino Observational Outlooking Trial on Hypertension) study was to explore hypertension awareness, treatment and control and the associated metabolic abnormalities and risk factors in the population of San Marino, a small state in the Mediterranean area, for which limited evidence is available. METHODS Nine general practitioners enrolled 4590 consecutive subjects (44% of the San Marino population age 40-75 years), seen in their office by collecting history, physical and laboratory data and office blood pressure (BP) measurements. RESULTS Of these subjects, 2446 were normotensive and 2144 hypertensive; 62.3% of hypertensive patients were aware of their condition, 58.6% were treated (monotherapy 31.5%, combination therapy 27.1%), and 21.7% were controlled. Hypertension awareness and treatment were more frequent above age 50 and in females; BP control was similarly low in both genders. As compared to normotensives, hypertensive subjects were less frequently smokers (20.1 versus 27.8%), had greater body mass index (28.1 +/- 4.5 versus 25.8 +/- 3.7 g/m), and a higher prevalence of diabetes mellitus (15.8 versus 6.3%), lower high-density lipoprotein (HDL) cholesterol and higher prevalence of increased blood total cholesterol (66.1 versus 51.3%), triglycerides and serum uric acid. Values of subjects with 'high-normal' blood pressure were closer to those of hypertensive subjects. The prevalence of metabolic syndrome was higher in hypertensive than in normotensive subjects, and in treated than in untreated hypertensives. CONCLUSIONS Even in a small Mediterranean country with high health-care standards, hypertension awareness, treatment and control are inadequate and hypertension clusters with metabolic abnormalities and risk factors as in non-Mediterranean areas.

Abstract
High rates of uncontrolled hypertensives have been reported in France as well as in other countries, partly owing to an inadequate management of hypertension by clinicians. The objectives of the study were (1) to describe the therapeutic decisions faced by general practitioners (GP) in hypertensives not controlled by fixed-dose combination antihypertensive therapy with a renin-angiotensin system (RAS) inhibitor and a diuretic (D) and (2) to evaluate the frequency with which ambulatory blood pressure monitoring (ABPM) is used in these patients. Each GP had to include five uncontrolled hypertensives on fixed-dose RAS inhibitor and D combination. A total of 2118 GPs included 9551 patients; 8643 patients were receiving at least one of the two drugs at a low dose (group 1) and the remaining 908 patients were receiving high doses of both drugs (group 2). The most common therapeutic choice was that of a new combination, either a fixed-dose in one pill or with separate preparations: 65% (n=5621) in group 1 and 56% (n=505) in group 2. An increase in dose was chosen in 28% of patients in group 1 (n=2467) and continuation of treatment without modification in 27% of patients in group 2 (n=242). A third active principle was only added in 2.5% of patients in group 1 (n=219) and 11% in group 2 (n=103). Ambulatory blood pressure monitoring was employed in 25% of patients (n=2413). An improvement in hypertension management should be expected from the implementation of the 2005 French guidelines.

Abstract
OBJECTIVE The aim of the present study was to identify the association between mental disorders and awareness and treatment of hypertension in a large representative community sample. METHODS The analysis was based on data from 4149 respondents, ages 18 to 65 years, from the German National Health Interview and Examination Survey, a nationally representative multistage probability survey conducted from 1997 to 1999. Mental disorders were assessed by a modified version of the Composite International Diagnostic Interview. Blood pressure was measured during the medical examination by a health examiner. RESULTS There was no general association between awareness of hypertension and affective, anxiety, and substance abuse/dependence disorders. Men with acknowledged but untreated hypertension more often experienced affective and substance abuse/dependence disorders than men with treated hypertension. These relationships were stable after adjustment for sociodemographic and clinical characteristics. CONCLUSIONS Our results suggest that it is important to distinguish between treated and acknowledged but untreated hypertension when evaluating the associations between mental disorders and hypertension.

Abstract
BACKGROUND Large clinical trials have emphasized that blood pressure control provides a major clinical benefit in reducing the risk of blindness in patients with diabetic retinopathy. METHODS This audit was carried out to assess the quality of care for hypertension in 100 consecutive type II diabetics with diabetic retinopathy. RESULTS The target blood pressure of 140/80 mmHg was achieved only in 38% of the patients. We also observed that 65% of the patients requiring diabetic macular laser treatment in this cohort had suboptimal control. The factors associated with suboptimal blood pressure control are identified and discussed. CONCLUSION Despite the unequivocal fact that lowering BP significantly reduces morbidity and mortality in diabetics, the majority of patients are not treated to a goal BP.

Abstract
OBJECTIVE To study management of hypertension in the elderly in a large population-based study and to evaluate the prevalence of hypertension and factors related to awareness, treatment, and control. DESIGN The Three City study, a population-based study among 9693 non-institutionalized individuals aged 65 years and over. METHODS Blood pressure was measured with an automated electronic device, and treatment assessed, during home interview. Hypertension was defined by a mean blood pressure of two measurements superior to or equal to 160/95 mmHg and/or the intake of antihypertensive medications. RESULTS In the final working sample of 9090 people, 62% were hypertensive. More than two-thirds were aware of their hypertension and 81% were treated with antihypertensive drugs. Among 4573 treated hypertensive participants, 35% had a blood pressure over 160/95 mmHg and 69% over 140/90 mmHg. Women were more frequently aware of their hypertension, more frequently treated, and more frequently controlled than men. A history of cardiovascular disease, high body mass index, diabetes and high frequency of visits to the general practitioner were related to higher percentages of awareness and treatment. Among treated hypertensive patients, those with a history of cardiovascular events or who visited their general practitioner more often or who more often had their blood pressure measured were more frequently controlled. Awareness was strongly associated with treatment, but was inversely related to control of hypertension among treated hypertensive patients. CONCLUSIONS Management of hypertension, and particularly its control among treated hypertensive patients, needs to be improved in people aged 65 years and over.

Abstract
OBJECTIVES The aim of this longitudinal, open-label, comparative, multicenter study was to assess cognitive function in hypertensive patients receiving mid-term treatment with lercanidipine. METHODS Hypertensive patients aged 40 years or older were treated with lercanidipine (10 mg daily) after 7-10 days washout period. The duration of the study was 6 months. Blood pressure (BP) was measured every 4 weeks (JNC 6th report). In patients with inadequate BP control, doxazosin was added and up-titrated. At baseline and after 6 months of treatment, cognitive function was evaluated using the Spanish validated version of the Mini-Mental State Examination (MMSE) and the Trail Making Test (TMT). RESULTS In the study population of 467 patients, BP decreased from 154.4/95.3 mmHg at baseline to 134.8/80.7 mmHg at 6 months. At the end of the study, 98% of patients were receiving lercanidipine, 20% an angiotensin-converting enzyme inhibitor, and 6% doxazosin. Adequate BP control was obtained in 68% of patients. The mean (standard deviation) MMSE scores improved from 32.35 (2.59) to 33.25 (2.36) (p < 0.0001). Patients with good BP control scored significantly better than those with inadequate BP control (p < 0.05), which was already observed at the first month. CONCLUSIONS The third-generation calcium channel antagonist, lercanidipine, improved cognitive function after 6 months of treatment especially in patients with good BP control, suggesting that improvements in cognitive function may be associated with a decrease in BP.

Abstract
β-blockers have been widely used for the treatment of hypertension, congestive heart failure and angina, as well as in the post-myocardial infarction population. Both β1 selective and nonselective agents are available. Nebivolol is a new highly β1 selective antagonist with a nonadrenergic, nitric oxide potentiating vasodilatory property, which is unique among β-blockers. In addition, nebviolol does not inhibit the increase in the heart rate response to exercise, which is unique among β-blockers. Nebviolol has been tested successfully in double-blind, placebo-controlled trials in both hypertension and congestive heart failure.

Abstract
UNLABELLED For some years now, the recommendations of scientific societies have significantly reduced the therapeutic targets for blood pressure, glycaemia and lipid levels in diabetic patients. However, little is known regarding the synchronization between effective risk factor management and the guidelines. To examine this issue, the Phenomen survey was conducted between January and July 2001 on 16358 patients suffering from hypertension followed by a general practitioner in France. AIM To evaluate the control of cardiovascular risk factors in patients with diabetes and hypertension according to the French guidelines. METHODS AND PATIENTS 8177 general practitioners, selected from a national database according to quotas, taking into account age, practice and area, had to include the first two hypertensive patients they came across in their practice and to collect their demographic data, cardiovascular risk factors and medications. RESULTS 2346 out of 16358 hypertensive patients presented with type 2 diabetes (14.3% of the cohort). The number of GP consultations in the last 12 months averaged 8.31. According to the French guidelines, 6.5% had a blood pressure<140/80 mmHg, a total of 38.7% patients met the goal of LDL cholesterol level and 26.6% of patients had an HbA1c<6.5%, 53.4% of patients had an HbA1c between 6.6 and 8%. 37.1% of patients continued to receive antihypertensive monotherapy but only 3% in this monotherapy group reached the target of 130/85 mmHg. 29% of the patients were on antiplatelet therapy. 64.6% of these hypertensive diabetic patients presented with more than three other cardiovascular risk factors. Based on WHO recommendations, 0.3% of the patients met all of the blood pressure, lipid and glycaemic treatment objectives. CONCLUSION Despite frequent monitoring by a general practitioner, the overall management of modifiable risk factors in this diabetic hypertensive population is clearly inadequate. The impact of the guidelines on effective management remains limited and additional information is required to understand why physicians are not more aggressive in managing modifiable risk factors in diabetic patients.

Abstract
OBJECTIVE The congruence between self-rated health and objective health was examined for associations with health factors related to hypertension (health behaviors, medication barriers, and perceived blood-pressure control). METHODS The Charlson Comorbidity Index was cross classified with self-rated health, producing four health-congruence groups: good health realists, poor health realists, health optimists, and health pessimists. Data for this study were obtained from 588 hypertensive veterans (mean age = 63) at baseline of a clinical trial to improve blood-pressure control before randomization to an intervention. RESULTS Optimists had higher perceived control of their hypertension when compared to pessimists. Additionally, optimists had higher levels of exercise and fewer medication barriers when compared to poor health realists. DISCUSSION Health congruence classification could be a useful tool to alert practitioners of patients who may be having difficulties managing their hypertension.

Abstract
This present study assessed the antihypertensive efficacy of the fixed combination of manidipine and delapril by ambulatory blood pressure monitoring in patients with hypertension inadequately controlled by monotherapy with either component. After a 2-week placebo period, 55 mild to moderate hypertensive patients were randomized to manidipine 20 mg o.d. or delapril 30 mg b.i.d. for 4 weeks. After this period, 30 patients, aged 30-76 years (18 males and 12 females) whose diastolic blood pressure was not adequately controlled (> or = 90 mmHg) by monotherapy were treated with the fixed combination of manidipine 10 mg plus delapril 30 mg o.d. for 8 weeks. A 24-h ambulatory blood pressure monitoring recording was performed at the end of the placebo washout, of the monotherapy and of the combination therapy. Blood pressure control over the 24 h was quantified by the trough-to-peak ratio and the smoothness index. As compared to placebo, the fixed combination of manidipine and delapril produced a statistically significant (p<0.01) decrease in sitting clinic (18 +/- 9/14 +/- 5 mmHg) and 24-h blood pressure (12 +/- 7/10 +/- 5 mmHg) without affecting heart rate. This reduction was greater than that observed with single components. At the end of the 8-week combination treatment period, the rate of normalilized patients was 73%. Treatment with the fixed combination was associated with a positively high smoothness index (1.2 +/- 0.7/13.8 +/- 0.8) and with a relatively good trough-to-peak ratio (0.46/0.60). The combination of manidipine and delapril produced significant and smooth reductions in blood pressure values, which persisted over the 24-h dosing interval. These results support the use of fixed manidipine-delapril combination in the treatment of mild to moderate hypertensive patients inadequately controlled by monotherapy.

Abstract
The Japan Home versus Office Blood Pressure Measurement Evaluation (J-HOME) study was conducted to measure the control of blood pressure (BP) as evaluated by home BP measurement among 3,400 patients with essential hypertension (mean age: 66 years; females: 55%) receiving antihypertensive treatment in primary care settings in Japan. The purpose of this first report was to compare characteristics of BP control as measured at home and in the clinic (office) and define their association with BP control as evaluated by physicians. Mean systolic/diastolic BP (SBP/DBP) values were 140/82 mmHg for home BP and 143/81 mmHg for office BP. BP levels were not adequately controlled among approximately 60% of the patients, according to reference values described in the national guidelines (office BP: <140/90 mmHg; home BP: <135/85 mmHg). Even among patients evaluated by physicians as having excellent or fairly good BP control, office and home SBP values were insufficiently controlled in approximately 50%. Although the tendency was more remarkable among older patients, whose recommended target BP levels are higher than those of middle-aged patients in the Japanese Hypertension Society 2000 criteria, office and home BP values were not adequately controlled in approximately 50% of the middle-aged patients whose BP control was evaluated as good. Our findings suggest that an important reason why home and office BP values are not adequately controlled is that physicians approve relatively higher BP levels under treatment, even among middle-aged patients.

Abstract
OBJECTIVE To describe characteristics of hypertension in French Caribbean regions. DESIGN A cross-sectional worksite study. SETTING AND PARTICIPANTS A random sample of 6136 workers referred for annual check-up from Martinique, French Guyana and Guadeloupe. An average of three consecutive measurements was taken as the blood pressure (BP) level. An additional visit was required in subjects not taking antihypertensive medications with an average BP over 140/90 mmHg. INTERVENTIONS None. MAIN OUTCOME MEASURES Hypertension prevalence, awareness, treatment and control. RESULTS The age-specific prevalence of hypertension, based on two visits, increased from 3.2% in men below 30 years to 46.9% in those older than 50 years. The corresponding values found in women were 1.8 and 42.6%. The overall prevalence was 19.5% in men and 18.9% in women. The rate of awareness remained low while age increased. The use of antihypertensive medications slowly increased with age, but overall the rate remained lower in men compared with women. Up to 71% of hypertensive women received antihypertensive medications. Compared with previous studies, a high proportion of adequately treated patients was found among women (44.9%). Only 30.4% of hypertensive men were treated, and as a result the control rate was lower (13.3%). CONCLUSION Major sex-related differences are found in the control of high BP, with an unexpected high rate observed among Caribbean women. Better awareness and higher treatment rates play an important role in explaining such results. This may be important, especially in developing countries, where poor control of hypertension is a major cause of cardiovascular diseases.

Abstract
BACKGROUND Persistence is a key factor for long-term blood pressure control, which is of high prognostic importance for patients at increased cardiovascular risk. Here we present the results of a post-marketing survey including 4769 hypertensive patients treated with irbesartan in 886 general practices in Switzerland. The goal of this survey was to evaluate the tolerance and the blood pressure lowering effect of irbesartan as well as the factors affecting persistence in a large unselected population. METHODS Prospective observational survey conducted in general practices in all regions of Switzerland. Previously untreated and uncontrolled pre-treated patients were started with a daily dose of 150 mg irbesartan and followed up to 6 months. RESULTS After an observation time slightly exceeding 4 months, the average reduction in systolic and diastolic blood pressure was 20 (95% confidence interval (CI) -19.6 to -20.7 mmHg) and 12 mmHg (95% CI -11.4 to -12.1 mmHg), respectively. At this time, 26% of patients had a blood pressure < 140/90 mmHg and 60% had a diastolic blood pressure < 90 mmHg. The drug was well tolerated with an incidence of adverse events (dizziness, headaches,...) of 8.0%. In this survey more than 80% of patients were still on irbesartan at 4 month. The most important factors predictive of persistence were the tolerability profile and the ability to achieve a blood pressure target < or = 140/90 mmHg before visit 2. Patients who switched from a fixed combination treatment tended to discontinue irbesartan more often whereas those who abandoned the previous treatment because of cough (a class side effect of ACE-Inhibitors) were more persistent with irbesartan. CONCLUSION The results of this survey confirm that irbesartan is effective, well tolerated and well accepted by patients, as indicated by the good persistence. This post-marketing survey also emphasizes the importance of the tolerability profile and of achieving an early control of blood pressure as positive predictors of persistence.

Abstract
The objectives of the study were to appraise the knowledge which the patients have about their hypertension, and to assess the knowledge and involvement of pharmacists in the management of the hypertensive patient. All the pharmacies in the Poitou-Charentes area were invited both to participate in a training session about arterial hypertension and asked to fill in a pharmacist's questionnaire. Furthermore, each participant was required to submit a patient's questionnaire to 20 consecutive hypertensives. A total of 104 pharmacies and 1015 hypertensive patients participated in the survey. In all, 88% of the patients (n = 893) were aware of their blood pressure (BP) figures, but 68% (349/515) considered themselves wrongly, to be normalized; 39% (n = 350) only had BP figures <140/90 mmHg. They said they had been poorly informed about recommended lifestyle changes. In all, 18% (n = 185) were equipped with an automatic device. A total of 77% (n = 779) were able to give the names of their drugs without the help of the pharmacist. Treatment-related unwanted effects were reported by 8% of the patients (n = 79). Only 18% (n = 29) of the pharmacists were able to provide a correct definition of hypertension. Most of them thought hypertension was well controlled in the general population and considered that both tolerance of and compliance with antihypertensive treatment were satisfactory. They could most often (80%, n = 135) supply a SBPM device, but 58 (36%) only were able to provide relevant advice regarding the recommended procedures. In conclusion, The BP goals and the lifestyle modifications are poorly known by the hypertensives. Pharmacists' knowledge is frequently wrong and should be improved by appropriate training programmes.

Abstract
OBJECTIVE Hypertension is often poorly controlled, despite its importance and despite the availability of very effective treatments. An under-recognized problem is the failure of consensus guidelines to acknowledge the important difference between efficacy in clinical trials and effectiveness in clinical practice. The present survey was designed to prospectively assess what is the target blood pressure (BP) goal defined by a general practitioner (GP) for an individual patient, and what are the reasons for not modifying an antihypertensive drug regimen, when pre-defined individual BP goals are not achieved. DESIGN Family practice based, open intervention survey. SUBJECTS Participating GPs enrolled 2621 hypertensive patients. At the first visit each physician was required to assess the cardiovascular risk profile of each patient and to define individual BP targets. INTERVENTIONS Treatment was started with irbesartan alone or in fixed combination with hydrochlorothiazide. Follow-up visits were suggested after 1 month, 2 months and 4 months. Physicians were asked to report BP values under the new treatment regimen and to indicate whether in their opinion pre-defined BP targets set at baseline were achieved or not and whether the antihypertensive regimen was modified or maintained in relation to whether target BP was reached or not. MAIN OUTCOME MEASURE To provide reasons for not changing the treatment even though BP goals were missed. RESULTS Average target BP values defined by the physicians at baseline were 138 +/- 8 mmHg for systolic and 84 +/- 5 mmHg for diastolic BP. Among GPs, defined target BP values did not depend on individual risk stratification, but rather depended on baseline BP values. At baseline systolic and diastolic BP averaged 165/97 +/- 17/10 mmHg, while at the last visit achieved BP averaged 140/84 +/- 14/8 mmHg. There were three main reasons for not intensifying antihypertensive treatment when BP targets were not achieved. These reasons were: (1). the assumption that the time after starting the new drug was too short to appreciate its full effect (44% at first, 14% at last follow-up), (2). that there was a clear improvement or the target BP was almost reached (24% at first, 34% at last follow-up) or (3). that self-measurements were considered satisfactorily (10% at the last visit). CONCLUSIONS Failure of physicians to follow guidelines is apparently dependent on the belief that baseline BP dictates the target, that a clear improvement in BP might be sufficient and that the full drug effect may take up to 4 months or more to be attained.

Abstract
THE AIMS OF OUR STUDY WERE (i). to estimate the yearly incidence rates based on one vs two visits in a working population and (ii). to identify incident hypertension modifiable risk factors. A total of 21566 normotensive subjects were included in a 1-year cohort study. Blood pressure (BP) levels at inclusion and at the second year screening were measured on the basis of two visits, that is, if BP was over 140/90 mmHg in untreated subjects, they were invited to a control visit 1 month later. Height and weight were measured and behavioural risk factors were collected. Among the 17465 subjects who completed the entire protocol (9691 men and 7774 women), 17026 remained normotensive at a 1-year interval and 439 (325 men and 114 women) became hypertensive. Crude yearly incidence rates based on one visit were 6.21% in men and 3.06% in women, compared with 3.04% in men and 1.34% in women when incidence rates were based on two visits, a more than twofold difference. Age and body mass index at baseline were the two major independent determinants of incident hypertension in both genders. Smoking and alcohol consumption were significant risk factors in men but not in women, and a low educational level only in women. BP measurement on separate occasions is necessary to avoid overestimation of incidence. Weight in both genders and alcohol consumption in men were the main modifiable predictors of hypertension.

Abstract
THE POSITIVE IMPACT OF TREATMENT: Antihypertensive treatments have clearly demonstrated their capacity to reduce cardiovascular mortality. The limits to the reduction in risk are imputable to insufficient early management, morbidity and poor compleance insufficiency of pharmacological treatments, absence of individualised adaptation to the causal pathology and inappropriate management of other cardiovascular risk factors. TO IMPROVE MANAGEMENT: Rather than creating more cardiovascular prevention Centres which only concern specific cases and research, it is fundamental to provide physicians, nurses and other health care workers with greater competence in hypertension and the management of cardiovascular risks. Conceptual changes are also necessary, particularly in that which concerns the end of the dichotomy between normotension and hypertension, hypercholesterolemia and normocholesterolemia and its individual and populational impact. PROMOTION OF NUTRITIONAL MEANS: Nutritional means should not be forgotten applied to accompany the whole pharmacological treatment of hypertension, they can be used for individual prevention and for reduction of the incidence of high blood pressure in the general population. NEW THERAPEUTIC STRATEGIES: Other than the search for antihypertensive drugs with greater efficacy and improved tolerance, several targets should be envisaged such as optimising the blockage of the renin-angiotensin-aldosterone system, inihibiting aldo-synthase. A CONSERVATIVE ATTITUDE: Although attractive, the individualisation of treatment based on genetic analysis will not be accessible to the majority of hypertensive patients. The attitude to be considered in 2004 consists above all in improving the use of available drugs at appropriate doses and especially in combinations at fixed-doses to allow for an easier therapeutic schedule.

Abstract
Heart failure (HF) is a progressively debilitating disorder characterized by frequent hospital admissions and high annual mortality rates. Coronary artery disease (CAD), hypertension, and aging are major risk factors for the development/progression of HF. For years, most of the attention has been focused on HF caused by reduced left ventricular (LV) systolic function, largely attributable to CAD. It is now generally accepted that nearly 50% of elderly patients with HF might have normal or preserved LV systolic function. This condition is commonly referred to as a distinct type of HF caused by LV diastolic dysfunction, and it often accompanies hypertensive heart disease. Isolated diastolic HF is increasingly recognized as the dominant cause of symptoms and hospitalizations from HF in a large proportion of individuals aged 65 and older. However, the clinicians caring for patients with diastolic HF do not fully understand its cause, how it progresses, or how it could be appropriately diagnosed and treated. Because varying degrees of systolic and diastolic dysfunction might coexist in any individual patient, and given the limitation of current diagnostic tools, the overall impact of isolated diastolic HF continues to evolve. Ongoing clinical trials are testing new strategies for treatment of diastolic HF.

Abstract
Hypertension is a major risk factor for cardiovascular morbidity and mortality. Monotherapy of hypertension is often ineffective, since it controls approximately 50% of the blood pressure of hypertensive patients. For lowering blood pressure to less than 140/90 mmHg (or <130/80 mmHg among people with diabetes or chronic renal disease) according to JNC-7 guidelines, combination therapy of two or more drugs is often necessary. The combination of a diuretic with an angiotensin-converting enzyme inhibitor (ACEI) or an angiotensin receptor blocker (ARB) is effective and provides the additional benefit of blocking the effects of angiotensin II, which is responsible for cardiovascular remodeling and its complications. ARBs may have an advantage over the ACEIs because they block the action of all angiotensin II directly, whereas ACEIs are ineffective in blocking angiotensin II generated by nonclassical ACE pathways. Valsartan (Diovan, Novartis) is one of the seven currently approved ARBs in the USA for the treatment of hypertension, and it has been shown to be very effective in controlling blood pressure given once-daily in doses of 80-160 or 320 mg. Its fixed combination with hydrochlorothiazide (HCT) is even more effective in controlling blood pressure in 70% of the cases. The most commonly used combinations are valsartan/HCT (Diovan/HCT), 80/12.5 and 160/12.5 mg given once-daily.

Abstract
Cross-sectional surveys on prevalence, treatment and control of hypertension could not satisfactorily distinguish between diastolic hypertension and isolated systolic hypertension because the definition of hypertension included patients under pharmacological treatment. We assessed the situation in the two types of hypertension in general practice in Belgium, based on current blood pressure (BP) measurements and on BP prior to the initiation of drug therapy. Participating physicians enrolled the first 15 at least 55-year-old men visiting the surgery, measured their BP and recorded data on medical history including pretreatment BP, drug utilization, cardiovascular risk factors and target organ damage. Diastolic hypertension was defined as diastolic BP> or =90 mmHg, irrespective of systolic BP, and isolated systolic hypertension as systolic BP > or =140 mmHg and diastolic BP < 90 mmHg. Among 3761 evaluable patients, 74% were hypertensive. Among the 1533 hypertensive patients in whom blood pressure was known prior to treatment (n=965) or who were untreated at the study visit (n=568), 1164 had diastolic hypertension and 369 isolated systolic hypertension. The prevalence of antihypertensive treatment was, respectively, 75 and 25% (P<0.001) in these two types of hypertension. The odds of being treated were independently determined by type of hypertension, severity of hypertension and level of risk (P<0.001). BP was controlled in 25% of all patients with diastolic hypertension and in 13% of all patients with isolated systolic hypertension (P<0.001). About half of the treated patients with systolic hypertension were on a diuretic and/or a calcium-channel blocker. In conclusion, isolated systolic hypertension is less frequently treated than diastolic hypertension, overall BP control is poor and actual drug therapy diverges from recommendations based on placebo-controlled intervention trials.

Abstract
OBJECTIVES To determine how well and to what extent blood pressure (BP) is controlled in diabetic hypertensive patients treated by primary care doctors, and to evaluate drug therapy in the backdrop of risk factors and laboratory findings. METHODS A therapeutic audit of the medical records of diabetic hypertensives from nine primary care health centres in Bahrain. RESULTS In 266 diabetic hypertensives (82 males and 184 females), the recommended target BP < 130/< 85 mmHg (WHO/ISH guidelines, 1999) was achieved in 20 (9.8%) with a BP of 119 +/- 4/76 +/- 5 mmHg. Among those who did not achieve target BP, 70 (34.5%) lacked systolic BP control (BP = 153 +/- 17/79 +/- 3 mmHg), four (2%) lacked diastolic BP control (BP = 123 +/- 3/86 +/- 3 mmHg) and 109 (53.7%) lacked both systolic and diastolic BP control (BP = 158 +/- 20/94 +/- 7 mmHg). The mean age of the group achieving target BP was significantly lower than the group which lacked systolic BP control (51.6 +/- 9 vs. 63.5 +/- 9 years; P < 0.0001). While there were no significant differences in fasting blood glucose, glycosylated haemoglobin, triglycerides, urea, creatinine, uric acid and serum electrolytes between the group achieving target BP vs. groups without target BP, a significant difference in total cholesterol was seen. PATIENTS with ischaemic heart disease and/or isolated systolic hypertension did not achieve the target BP. Antihypertensive monotherapy was prescribed in 145 (54.5%) patients, whereas two- and three-drug combinations were prescribed in 32.3 and 8.2% of patients, respectively. As monotherapy, angiotensin-converting enzyme (ACE) inhibitors were the most frequently prescribed drugs followed by beta-blockers, calcium channel blockers (CCBs) and diuretics. As two-drug combinations, an ACE inhibitor with a beta-blocker/diuretic and a beta-blocker with a CCB/diuretic were usually prescribed. CONCLUSIONS According to the WHO/ISH 1999 guidelines, approximately one out of 10 diabetic hypertensives achieved target BP control. In many instances, the drug therapy prescribed was inappropriate considering the comorbidity in patients and their laboratory findings. Improved BP control is needed in treating high-risk groups such as patients with diabetes mellitus, and efforts should be made to improve the treatment of hypertension in the primary care setting.

Abstract
OBJECTIVE Assess capacity of health-care facilities in a low-resource setting to implement the absolute risk approach for assessment of cardiovascular risk in hypertensive patients and effective management of hypertension. DESIGN AND SETTING A descriptive cross-sectional study in Egbeda and Oluyole local government areas of Oyo State in Nigeria in 56 randomly selected primary- (n = 42) and secondary-level (n = 2) health-care and private health-care (n = 12) facilities. PARTICIPANTS One thousand consecutive, known hypertensives attending the selected facilities for follow-up, and health-care providers working in the above randomly selected facilities, were interviewed. RESULTS About two-thirds of hypertensives utilized primary-care centers both for diagnosis and for follow-up. Laboratory and other investigations to exclude secondary hypertension or to assess target organ damage were not available in the majority of facilities, particularly in primary care. A considerable knowledge and awareness gap related to hypertension and its complications was found, both among patients and health-care providers. Blood pressure control rates were poor (28% with systolic blood pressure (SBP) < 140 mmHg and diastolic blood pressure (DBP) < 90 mmHg] and drug prescription patterns were not evidence based and cost effective. The majority of patients (73%) in this low socio-economic group (mean monthly income 73 US dollars) had to pay fully, out of their own pocket, for consultations and medications. CONCLUSIONS If the absolute risk approach for assessment of risk and effective management of hypertension is to be implemented in low-resource settings, appropriate policy measures need to be taken to improve the competency of health-care providers, to provide basic laboratory facilities and to develop affordable financing mechanisms.
