    Full Text Available Arterial hypertension is a major risk factor that predisposes to cardiovascular disorders and is responsible for most of the morbidity and mortality in patients. Hypertension is closely associated with the kidney, because kidney disease can be both the cause and consequence of increased blood pressure. Elevation of blood pressure is a strong independent risk factor for hypertensive nephropathy and development of ESRD. The pathogenesis of ischemic hypertensive nephropathy (IHN is multifactoral, and in addition to blood pressure other factors contribute to the development of this renal pathology and its progression to end-stage renal disease. These include obesity, smoking, male gender and other still unknown risk factors. The aim of this paper was to analyse the association between essential arterial hypertension and renal hypertensive disease and prevalence of other atherosclerotic risk factors in patients with developed hypertensive renal disease. In this prospective cross sectional study 283 patients of both genders with diagnosed essential hypertension and hypertensive renal disease were analysed. The anamnestic data related to age, duration of hypertension, history of smoking, presence of hypertensive retinopathy, hypertrophy of the left chamber and data about previous renal diseases were collected through conversation and medical documentation. The clinical examination comprise determination of blood pressure, body mass index (BMI, lipid parameters (total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides, serum urea and creatinine, urine, albumin and protein concentration. The total number of 283 patients (185 males and 98 females with HN was analyzed. The analysis revealed significantly higher proportion of males aged over 60 years with IHN. The mean age of examined hypertensive patients with IHN is 62.6±8.8 years with duration of hypertension 19.8±5.9 years. All examined patients had hypertensive retinopathy and

    Chinese populations are known to be at risk for vitamin D deficiency, with some evidence that this is due to lack of exposure to sunlight. Vitamin D deficiency and/or low sun exposure have been associated with higher incidence of hypertension in Caucasians. Thus, we investigated these associations in a Chinese population with a high rate of hypertension. From a random household survey of 1410 residents aged ≥18 years, height, weight and blood pressure were measured and demographic, exercise and dietary data were collected, as well as estimated hours of sunlight exposure on weekdays and weekends (in winter and summer). Modifiable predictors of hypertension in these data were lack of sunlight exposure and low intake of fish as well as smoking, obesity and lack of exercise. When investigated in a linear model, sunlight exposure was negatively associated with hypertension (β=-0.072, pexposure per day compared to none was associated with less hypertension (OR=0.6, 95% CI: 0.4-0.8). Similarly, consuming either oily fish or seafood more than four times per week compared to less was also associated with less hypertension (oily fish (OR=0.4, 95% CI: 0.3-0.5); seafood consumption (OR=0.8, 95% CI: 0.7-0.9)). Having daily moderate physical activity compared to none was also associated with a lower risk of hypertension (OR=0.8, 95% CI: 0.7-0.9). In contrast, being obese compared to normal weight and having more than five pack-years of smoking compared to none were associated with a higher risk of hypertension (OR=4.6, 95% CI: 3.7-5.7; OR=1.4, 95% CI: 1.0-1.8, respectively). The major new findings of this study are that more sun exposure and high weekly fish consumption (especially oily fish) may be potentially modifiable independent factors for protecting against risk of hypertension in this population.

    Full Text Available Essential hypertension is one of the most emphasized psychosomatic disorders. Age, sexuality, excessive salt and alcohol consumption, lower activity level, fatigue, personality traits, emotional factors and stress are some of the risk factors for essential hypertension. The presence of emotional factors in the etiology of the essential hypertension and the emergence of psychiatric symptoms in the course of the illness has driven considerable attention from mental health workers on the disease for a long time. Some of the personality traits that make a person vulnerable to hypertension are being over controlled, being submissive, and hardworking. Hypertension is accepted to be a reaction against suppressed emotions and an adaptive and defense mechanism of the body. Among persons who are prone to hypertension, sympathetic nerve system is affected as a response to emotional stress and hypertension appears as a result of vasoconstriction and other autonomous responses. All at once, it was also shown that vasoconstrictor response continues much longer in hypertensive individuals than in normotensive patients. Autonomic response to stress almost always displays itself as hypertension in individuals who are prone to hypertension. Moreover, normotensive children of hypertensive parents also have elevation in blood pressures as a response to emotional stress almost without exception. The increase in sympathetic stimulus, re-modulation of bar receptors by structural and functional changes are the main features of the most commonly valid hypothesis in essential hypertension, currently. According to this hypothesis: as a result of emotional stress, inhibition over vasomotor center decreases and output of stimulus increases; epigenetic changes in endothelial structure of carotid sinus and/or aortic arch and/or vasomotor centers occurs; and finally stress increases sympathetic stimulus output. This situation leads to neurohormonal excitation; increases in

    Full Text Available Background Hypertensive crisis occurs in 1-4% of the hypertensive pediatric population, mostly due to acute glomerulonephritis (AGN. Some factors have been suggested to affect blood pressure (BP in children, such as age, sex, race/ethnicity, obesity, and socioeconomic status, but little is known for risk factors for hypertensive crisis in AGN.Objective To analyze the risk factors for hypertensive crisis in children with AGN.Methods Retrospectively, we studied possible risk factors for hypertensive crisis in children with AGN at Dr. Soetomo Hospital from 2007 to 2011. Hypertensive crisis was defined as systolic BP ≥180 mmHg or diastolic BP ≥120 mmHg (for children ≥ 6 years of age; and systolic and/or diastolic BP >50% above the 95th percentile (for children aged <6 years. We evaluated the demographic and clinical characteristics as potential risk factors. Statistical analysis was done with Chi-square, Fisher’s exact, and logistic regression tests. Variables with P <0.25 in the univariable analysis were further analyzed by the multivariable logistic regression model. A P value of < 0.05 was considered statistically significant.Results There were 101 children included (mean age 9.7 (SD 2.17 years, with a male-to-female ratio of 2.7:1. Hypertensive crisis occurred in 42 (41.6% children, of whom 8 had hypertensive urgency and 34 had hypertensive emergency. Proteinuria was seen in 53 children with AGN (52.5% and was the significant risk factor for hypertensive crisis in our subjects (OR=2.75; 95%CI 1.16 to 6.52; P=0.021. Gender, clinical profiles, ethnicity, nutritional status, blood urea nitrogen (BUN, and glomerular filtration rate (GFR were not significant risk factors for hypertensive crisis.Conclusion Proteinuria is the significant risk factor for hypertensive crisis in children with AGN.

    Full Text Available Hypertension is one of the most preventable chronic conditions. Improving hypertension awareness is a critical first step to reducing morbidity and mortality from hypertension in the elderly, yet the factors associated with hypertension awareness in China are poorly understood. The objective of this paper is to examine the extent to which older Chinese adults are aware of their hypertension, and factors associated with this awareness. We included 2,404 adults aged 60 years or older clinically identified as hypertensive from panel data surveyed in 1997, 2000, 2004, and 2006 as part of the China Health and Nutrition Survey (CHNS. Comparing this data with respondents’ self-reported diagnosis of hypertension enabled us to characterize hypertension awareness. Covariates included sociodemographic, health status, functional disability, and behavioral factors. Generalized estimating equations (GEE were used to identify factors for hypertension awareness. We found 22.9% in 1997 and 42.7% in 2006 of study participants were aware of their hypertensive status. Lower awareness was found among those who lived in rural areas (odds ratio [OR]=0.64, 95% Confidence Interval [CI], 0.47-0.88. Higher awareness was noted for persons who were aware of their hypertensive status in a previous survey wave (OR=7.43, 95% CI, 5.45-10.13, had high income (OR=1.55, 95% CI, 1.05-2.28, had stage two hypertension (OR=2.28, 95% CI, 1.69-3.06, had acute condition (OR=2.54, 95% CI, 1.89-3.42, and had greater activities of daily living (ADL limitations (OR=1.24, 95% CI, 1.08-1.43. Studying dynamics of hypertension awareness can help inform both clinical and public health approaches to improve healthcare.

    Hypertension is well known to one of the risk factors to reduce cognitive function, however, it is still unclear whether anti-hypertensive therapy is effective to prevent development of dementia or Alzheimer's disease. Epidemiological studies suggested antihypertensive therapy from the middle-age could reduce risk of dementia. The meta-analysis including HYVET also suggested blood pressure lowering from the elderly might be also effective to prevent development of dementia. The network meta-analysis and the cohort study using mega-data bank suggested ARB might be effective to prevent development of dementia or Alzheimer's disease compared to administration with other anti-hypertensive drugs. Although the further major clinical investigation is required, anti-hypertensive treatment might be useful to manage hypertensive patients with dementia.

    Full Text Available Background. The goal of this cross sectional study was to determine the prevalence of hypertension among the habitants of Branik and the presence of other risk factors, connected with hypertension.Methods. Between December 1987 and December 1988 the authors examined 745 persons older than 20 years, 60% of whole population in Branik. Examination included history, clinical examination, blood pressure and other laboratory measurements.Results. 23.4% of examined persons take antihypertensive drugs or are on low salt diet. The percent of hypertensive patients rises with age: from 2.3% (age 20–29 to 60.6% (age 80– 89. Most of hypertensive patients have moderate hypertension – 44.3%. The percent of hypertensive patients with normal body weight (NBW is significantly lower than the percent of normotensive persons with NBW (p < 0.01. Among the persons with more than 130% of ideal body weight, there is significantly more hypertensive patients than normotensives (p < 0.01. The proportion of hypertensive patients, who never add salt to the food, is significantly greater than the proportion of normotensive patients of the same group (p < 0.01. There are more heavy drinkers among hypertensive patients than normotensive persons. There are less cigarette smokers among hypertensive persons than normotensive. 4% of examined persons have diabetes mellitus. 60% of diabetics have also hypertension. 10.3% of hypertensive persons have diabetes mellitus.Conclusions. The prevalence of arterial hypertension was relatively high – 23.4%. The percent of hypertensive patients, who are overweight, is also higher than the percent of normotensive participants. Surprisingly, salt intake habits are healthier in hypertensive patients than in normotensive participants

    Hypertension is a significant medical and public health issue which puts an enormous burden on health care resources and the community. It is a chronic medical condition in which the systemic arterial blood pressure (BP) is elevated. Serious complications including cardiovascular and cerebrovascular diseases would be preventable if the rise in BP with age could be prevented or diminished. The majority of hypertensive patients require long-term treatment. Oral antihypertensive drugs, lifestyle modification including exercise and dietary modification are milestones for hypertension therapy. However, the control rate of hypertension hasn't reached the expected requirements currently. "Three lows" status quo, just low awareness, low treatment, and low control, are still the major problems confronting modern medicine. Recently, uncontrolled factors of blood pressure are widely concerned, which include insomnia, constipation, mood disorders, exogenous, etc. What's more, the control strategies of hypertension should not only pay close attention to "patient's high blood pressure", but also to "hypertensive patient". Therefore, the treatment of uncontrolled factors of blood pressure plays an important role in hypertensive therapy, which could be further research priorities.

    Full Text Available Despite the possibilities of contemporary pharmacotherapy, more than 80% of hypertensive patients do not achieve target blood pressure levels. Besides the obvious reasons – poor adherence of patients to treatment and non-rational therapy, there are other objective risk factors of resistance. Three main modifiable causes of resistant hypertension, that are often underestimated, are considered: obesity, obstructive sleep apnea syndrome and primary hyperaldosteronism. Understanding these mechanisms of resistance and their diagnostic criteria can improve the results of resistant hypertension treatment.

    Full Text Available Purpose: We aimed to retrospectively evaluate the risk factors for hypertensive attack during adrenalectomy in patients with pheochromocytoma. Despite the development of newer surgical and anesthetic techniques for the management of pheochromocytoma, intraoperative hypertensive attack continues to present a challenge. Materials and Methods: Data from 53 patients diagnosed with pheochromocytoma at Kyungpook National Uriversity Medical Center between January 2000 and June 2012 were retrospectively analyzed. The subjects were divided into 2 groups depending on the presence or absence of hypertensive attack at the time of surgery. Patient demographic characteristics and preoperative evaluations were assessed for their prognostic relevance with respect to hypertensive attack. A univariate analysis was conducted, and a multivariate logistic regression analysis was also performed. Results: In the univariate analysis, systolic blood pressure at presentation, preoperative hormonal status (including epinephrine, norepinephrine, vanillylmandelic acid, and metanephrine levels in a 24-hour urine sample, tumor size, and postoperative systolic blood pressure were significantly associated with the development of hypertensive attack. In the multivariate analysis, preoperative epinephrine level and tumor size were independent factors that predicted hypertensive attack. The highest odds ratio for tumor size (2.169 was obtained at a cutoff value of 4.25 cm and the highest odds ratio for preoperative epinephrine (1.020 was obtained at a cutoff value of 166.3 μg/d. Conclusions: In this study, a large tumor size and an elevated preoperative urinary epinephrine level were risk factors for intraoperative hypertensive attack in patients with pheochromocytoma.

    Full Text Available Hypertension is a common chronic disease in the elderly. This study aimed to determine the effects of age, ethnicity, gender, education, marital status, nutritional parameters, and blood elements on the risk of high blood pressure in the Malaysian elderly. This research was conducted on a group of 2322 non-institutionalized Malaysian elderly. The hierarchy binary logistic regression analysis was applied to estimate the risk of hypertension in respondents. Approximately, 45.61% of subjects had hypertension. The findings indicated that the female gender (Odds ratio (OR = 1.54, an increase in body weight (OR = 1.61, and an increase in the blood levels of albumin (OR = 1.51, glucose (OR = 1.92, and triglycerides (OR = 1.27 significantly increased the risk of hypertension in subjects (p < 0.05. Conversely, an increase in both dietary carbohydrates (OR = 0.74, and blood cholesterol level (OR = 0.42 significantly reduced the risk of hypertension in samples (p < 0.05. Furthermore, the results showed that ethnicity was a non-relevant factor to increase the risk of hypertension in subjects. It was concluded that female gender, an increase in body weight, and an increase in the blood levels of glucose, triglycerides, and albumin enhanced the risk of high blood pressure in the Malaysian elderly. In addition, an increase in both dietary carbohydrates and blood cholesterol level decreased hypertension in subjects.

    Full Text Available Introduction/Aim: The goal of our study was to analyze the epidemiological`s characteristics of ocular hypertension, as well as the influence of chronic risk factors on glaucoma development (conversion in glaucoma. We tried to make some entries for solving this complex ophthalmological problem. Material /Methods: From 2009 to 2015, a retrospective control study was performed on 121 patient with diagnoses of bilateral ocular hypertension and without disease progression/conversion of glaucoma (by standard protocols of diagnosis and basic procedures on tertiary level at Clinic of Ophthalmology, Clinical Centre of Kragujevac, Serbia.. The authors analyzed epidemiological characteristics: sex, age groups, positive/negative family history and personal history with chronic risk factors (one and/or two of ocular hypertension. The data obtained from this study were statistically analyzed in SPSS program, version 20.00. Results: As for the patients, 69 of them (57.02% were male and 52 female (42.98%. Dominant age group was between 40-49 (42.15% and then group between 50-59 (40.50% years of age. Anamnesis data indicated the absence of family anamnesis 71 (58.68%. Risk factors for ocular hypertension were presented in 103 (85.13% patients, 18 of them (14.87% did not respond. One risk factor - cardiovascular disease was noted in 83 (68.59%, with two risk factors - cardiovascular diseases and diabetes mellitus in 20 patients (16.53% and with PEX syndroma at other respondents. Conclusion: Ocular hypertension is not a common disease, but with risk factors, such as older age, positive family history, and chronic risk factors syndicated, represents a serious clinical and social problem, so the question remains for ophthalmologists - pro or against therapy? Those in favor of therapy would state the safety and protection from conversion/progression of glaucoma; but those  against therapy would only mention adequate monitoring of patients.

    Our aim was to clarify the perinatal outcomes of and risk factors for hypertension that is first detected after labor onset (labor onset hypertension, LOH), which may be a risk factor for eclampsia and stroke during labor. A total of 1349 parturient women who did not exhibit preeclampsia or gestational hypertension prior to labor were examined. The patients were classified into four groups: the normotensive (n=1023) (whose systolic blood pressure (SBP) remained below 140 mm Hg throughout labor), mild LOH (n=241) (whose maximum SBP during labor ranged from 140 to 159 mm Hg), severe LOH (n=66) (whose maximum SBP during labor ranged from 160 to 179 mm Hg) and emergent LOH groups (n=19) (whose maximum SBP during labor was greater than 180 mm Hg). The perinatal outcomes and patient characteristics of the four groups were compared. Twenty-four percent of the pregnant women who remained normotensive throughout pregnancy developed hypertension during labor. One of the patients in the emergent LOH group developed eclampsia. The blood pressure at delivery and frequencies of hypotensor use, interventional delivery and low Apgar scores differed significantly among the four groups. The following risk factors for severe/emergent LOH were extracted: being over 35 years old, a body mass index at delivery of >30, an SBP at 36 weeks' gestation of 130-134 mm Hg, an SBP at admission of 130-139 mm Hg, proteinuria (a score of 2+ on the dipstick test) and severe edema. The risk factors for severe/emergent LOH were identified in this study. In high risk cases, repeatedly measuring maternal blood pressure during delivery might help detect critical hypertension early.

    Hypertensive disorders of pregnancy (HDP) is one of the most important lethal complications in pregnant mothers. It is also associated with the subsequent development of chronic hypertension. The objective of this study was to identify the clinical risk factors of postpartum chronic hypertension in women diagnosed with HDP.Six hundred patients as HDP, who diagnosed and followed-up at least 6 month after delivery, were included in the study. We divided the included subjects in 2 groups based on the development of postpartum chronic hypertension: presenting with the chronic hypertension, "case group" (n = 41) and without chronic hypertension, "control group" (n = 559).Clinical and demographic factors were evaluated. By multiple regression analysis, early onset hypertension with end-organ dysfunction, smoking, higher prepregnancy body mass index (BMI), and comorbidities, systemic lupus erythematosus (SLE) or antiphospholipid syndrome (APLS), were associated with progression to chronic hypertension in the postpartum period. The value of area under the curves (AUC) for the 5 models, that generated to combine the significant factors, increased from 0.645 to 0.831, which indicated improved prediction of progression to the chronic hypertension. Additional multivariate analysis revealed significant specific risk factors.This retrospective single hospital-based study demonstrated that the clinical risk factors, that is early onset hypertension with end-organ dysfunction, smoking, and higher prepregnancy BMI, were significant independent predictors of chronic hypertension in women after delivery. Identification of risk factors allowed us to narrow the subject field for monitoring and managing high blood pressure in the postpartum period.

    Stephanie Hametner

    Full Text Available Clinically significant portal hypertension (CSPH, defined as hepatic venous pressure gradient (HVPG ≥10 mmHg, causes major complications. HVPG is not always available, so a non-invasive tool to diagnose CSPH would be useful. VWF-Ag can be used to diagnose. Using the VITRO score (the VWF-Ag/platelet ratio instead of VWF-Ag itself improves the diagnostic accuracy of detecting cirrhosis/ fibrosis in HCV patients.This study tested the diagnostic accuracy of VITRO score detecting CSPH compared to HVPG measurement.All patients underwent HVPG testing and were categorised as CSPH or no CSPH. The following patient data were determined: CPS, D'Amico stage, VITRO score, APRI and transient elastography (TE.The analysis included 236 patients; 170 (72% were male, and the median age was 57.9 (35.2-76.3; 95% CI. Disease aetiology included ALD (39.4%, HCV (23.4%, NASH (12.3%, other (8.1% and unknown (11.9%. The CPS showed 140 patients (59.3% with CPS A; 56 (23.7% with CPS B; and 18 (7.6% with CPS C. 136 patients (57.6% had compensated and 100 (42.4% had decompensated cirrhosis; 83.9% had HVPG ≥10 mmHg. The VWF-Ag and the VITRO score increased significantly with worsening HVPG categories (P<0.0001. ROC analysis was performed for the detection of CSPH and showed AUC values of 0.92 for TE, 0.86 for VITRO score, 0.79 for VWF-Ag, 0.68 for ELF and 0.62 for APRI.The VITRO score is an easy way to diagnose CSPH independently of CPS in routine clinical work and may improve the management of patients with cirrhosis.

Beside characteristics of the sample and blood pressure (BP, associated factors investigated were: - weight and body mass index (BMI, tea / coffee consumption, "added salt before tasting food", sleeping less than 8 hours per day and physical activity. Each student filled out stress and tension level tests. The school health team obtained informed parental consent to include their children in this study. Statistical analysis was done with EPI using chi-square, t-test, odd ratio (OR with 95% confidence limits (Cl and logistic regression with the 5% level for tests. The ethical committee of the faculty approved the study.Results / Finding: The prevalence of systemic hypertension was 10%. Children with high BP (23 were compared to 211 subjects with normotensive BP. High stress and tension score, less sleeping hours / day, adding salt to food and higher BMI were found significantly associated (p<0.05 with high BP. Study limitation: Researchers could assess preparatory schools children. However, primary and secondary school levels are separated in other schools and administrations. We used US standards for hypertension and BMI for children as local standards are not published.Conclusions: One tenth of 12

    Full Text Available Edyta Zbroch, Dominika Musialowska, Ewa Koc-Zorawska, Jolanta Malyszko Second Department of Nephrology and Hypertension with Dialysis Centre, Medical University of Bialystok, Bialystok, Poland Background: Hypertension in elderly patients is one of the main problems in cardiovascular diseases. The sympathetic nervous system hyperactivity seen in older patients is a known risk factor for hypertension and other cardiovascular events as well as chronic kidney disease. Renalase, secreted by the kidney and circulated in blood, may regulate the sympathetic tone by catecholamine degradation and in this way has an impact on cardiovascular and renal complications.Objective: To assess the impact of age on renalase and catecholamine concentration in hypertensive patients, including those on dialyses and its possible relation to blood pressure control and cardiovascular disease.Methods: The study cohort of 211 patients was divided into two groups according to age below 65 years (range 19–64 and above 65 years (range 65–86. The older group represented 38% of the whole studied population and 75% of them were dialyzed. The two groups of different ages were also divided into dialysis and nondialysis subgroups. The serum renalase, dopamine, and norepinephrine concentration together with blood pressure value and echocardiography were assessed.Results: Patients aged 65 years and more had higher renalase (20.59 vs 13.14 µg/mL, P=0.02 and dopamine (41.71 vs 15.46 pg/mL, P<0.001 concentration as well as lower diastolic blood pressure (75.33 vs 85 mmHg, P=0.001, advanced abnormalities in echocardiography, and more often suffered from diabetes and coronary artery disease. The significant correlation between age and renalase (r=0.16; P=0.019, norepinephrine (r=0.179; P=0.013, and dopamine (r=0.21; P=0.003 was found in the whole study population. In the nondialysis subgroup, 44% had chronic kidney disease, mostly in the stage 2 (83%. There was a significantly higher

    Hypertension is a major public health problem in Malaysia. A survey was initiated to examine the association of modifiable and non-modifiable risk factors for hypertension in Perak, Malaysia. A total of 2025 respondents aged 30 years and above were recruited using a multi-stage sampling method. Hypertension was defined as self-reported hypertension and/or average of two blood pressure readings at single occasion with SBP ≥ 140mmHg or DBP ≥ 90 mmHg. Body mass index (BMI) was defined using the Asian criteria and International Physical Activity Questionnaire (IPAQ) was used to evaluate physical activity. Body weight, height and blood pressure were obtained using standard procedures. Univariate analyses were conducted to examine the associations between risk factors and hypertension. Multiple logistic regression was used to examine each significant risk factor on hypertension after adjusted for confounders. In total, 1076 (54.9%) respondents were found to be hypertensive. Significant associations (p family history of hypertension. After adjusting for age, sex, ethnicity, education background, family history, BMI, physical activity, smoking and diet, respondents who were obese and had positive family history had higher odds for hypertension (OR:2.34; 95% CI:1.84-3.17 and 1.96 (1.59-2.42) respectively. A significant increase (p <0.001) in risk for hypertension was noted for age. Those with moderate physical activities were 1.40 (1.04-1.78) times more of having hypertension than those active. Poor diet score and smoking were not significantly associated with increased risk for hypertension. In conclusion, modifiable risk factors such as BMI and physical activity are important risk factors to target in reducing the risk for hypertension.

Male population in the age groups of 35 to 60 years was screened for hypertension from February 1986 to February 1987. Out of 340 subjects examined, 44 hypertensive cases were found, who were investigated for blood viscosity profile and were compared with 45 controls. The parameters studied were plasma viscosity, whole blood viscosity, red cell aggregation, red cell deformability and haematocrit W.H.O. criteria of hypertension (HT was strictly adhered to (B.P. above 160/95 mm of Hg. When compared to control group, plasma viscosity and whole blood viscosity were elevated in freshly detected and uncontrolled hypertensives. Red cell aggregation and deformability were significantly altered in chronic hypertensives than in normal, but haematocrit was not affected in any group.

    The objective of this study was to investigate the relationship between hypertensive patients and their coping style and associated lifestyle factors. A total of 502 participants attending nine outpatient clinics completed the validated Bahasa Malaysia version of the Coping Inventory for Stressful Situations and sociodemographic questionnaires. The height, weight, pulse rate and blood pressure of all the participants were measured using standardised methods. A total of 264 (52.6 percent) participants were hypertensive, while 238 (47.4 percent) were not. Participants with a high task-oriented score showed a significantly lower risk of hypertension compared to those with a low score (odds ratio [OR] 0.546; 95 percent confidence interval [CI] 0.371-0.804). Those with a high emotion-oriented coping score were associated with an increased risk of hypertension (OR 1.691; 95 percent CI 1.107-2.582). Hypertension was also significantly associated with a higher mean body mass index, positive family history of hypertension, history of diabetes mellitus and hypercholesterolaemia. In multiple logistic regression analysis with hypertension status as the dependent variable, a high emotion-oriented coping score, a low task-oriented coping score, age, body mass index, positive family history of hypertension and history of diabetes mellitus remain significant factors in the final model. These results indicated a significant relationship between hypertension and coping styles and lifestyle factors. They underscored the importance of further study as well as the development and implementation of intervention measures to improve coping skills among hypertensive patients, which may be incorporated into the management of hypertension.

    Full Text Available Background: Hypertension is the commonest cardiovascular disorder, posing a major public health challenge to population in epidemiological transition. The prevalence of hypertension increases with age and is more common in men as compared to women. But women loose this advantage after menopause due to estrogen deficiency. Objectives: 1. To assess the prevalence of hypertension and risk factors for hypertension among postmenopausal women in an urban community in Delhi. 2. To study association of risk factors with hypertension. Methodology: A community based cross-sectional study was conducted at Palam, an urbanized village in Delhi. A total 416 postmenopausal women were interviewed, examined and investigated. Results: Majority (78% of postmenopausal women were in the age group of 45-65 years. More than three fourth 342 (82.4% of women belonged to lower middle and upper lower socio-economic status. The prevalence of hypertension in these women was 39.6%, another one third (37% were pre-hypertensive. All women had one or more than one risk factor for hypertension. The most common risk factors were high salt intake (82.7%, low vegetable and fruit intake (64.2%, stress (53.2% and truncal obesity (36.1%. Risk factors like diabetes, obesity, smoking and physical inactivity were significantly more common in hypertensive as compared to non-hypertensive. Conclusion: Burden of hypertension among postmenopausal women in the present study was found to be high. Interventions integrating promotive, preventive and curative care for postmenopausal women should be provided to them.

    Full Text Available Essential hypertension accounts for 90% of all cases of hypertension. Though it is a one of major risk factors for cardiovascular diseases, it is a condition with its own risk factors. Overall prevalence of hypertension is increasing over the years in India (from 3.57% in 1977 to 20-30% after 1995. Considering the public health importance of ‘Essential Hypertension’ the present study was conducted. The objective was to study role of certain risk factors in essential hypertension. A case control study was conducted in rural township of Tasgaon; in Sangli district of Maharashtra during 2001-2002, to study role of certain modifiable risk factors in essential hypertension in 21-60 years age group. 165 cases of essential hypertension were selected by systematic random sampling from two private hospitals & O.P.D. of RHTC, Tasgaon and 330, age & sex matched controls were selected in the ratio of 1:2. A significant association was found between essential hypertension and various risk factors including smoking, its frequency and duration, alcoholic status, leisure time physical inactivity, restless sleep, BMI, mental stress, mixed diet and salt intake. Smoking of more than 10 cigarettes or bidi had 3.23 times risk of developing hypertension than smoking up to 10 cigarettes or bidi.

    Objectives To investigate correlation between retinal microvascular signs and essential hypertension classification. Methods The retinal microvascular signs in patients with essential hypertension were assessed with the indirect biomicroscopy lens, the direct and the indirect ophthalmoscopes were used to determine the hypertensive retinopathy grades and retinal arteriosclerosis grades.The rank correlation analysis was used to analysis the correlation these grades with the risk factors concerned with hypertension. Results Of 72 cases with essential hypertension, 28 cases complicated with coronary disease, 20 cases diabetes, 41 cases stroke,17 cases renal malfunction. Varying extent retinal arterioscleroses were found in 71 cases, 1 case with retinal hemorrhage, 2 cases with retina edema, 4 cases with retinal hard exudation, 5 cases with retinal hemorrhage complicated by hard exudation, 2 cases with retinal hemorrhage complicated by hard exudation and cotton wool spot, 1 case with retinal hemorrhage complicated by hard exudation and microaneurysms,1 case with retinal edema and hard exudation, 1 case with retinal microaneurysms, 1 case with branch retinal vein occlusion. The rank correlation analysis showed that either hypertensive retinopathy grades or retinal arteriosclerosis grades were correlated with risk factor lamination of hypertension (r=0.25 or 0.31, P<0.05), other correlation factors included age and blood high density lipoprotein concerned about hypertensive retinopathy grades or retinal arteriosclerosis grades, but other parameters, namely systolic or diastolic pressure, total cholesterol, triglyceride, low density lipoprotein cholesterol, fasting blood glucose,blood urea nitrogen and blood creatinine were not confirmed in this correlation analysis (P > 0.05).Conclusions Either hypertensive retinopathy grade or retinal arteriosclerosis grade is close with the hypertension risk factor lamination, suggesting that the fundus examination of patients with

    The study aimed to estimate the prevalence of hypertension in members of quilombos (slavedescendant African-Brazilian communities) and to evaluate possible associated factors. A population-based survey included 797 individuals 18 years or older. Hypertension was defined as systolic blood pressure ≥ 140mmHg or diastolic blood pressure ≥ 90mmHg or reported use of antihypertensive medication. We used Poisson regression with robust variance and hierarchical entry of variables. Prevalence of hypertension was 45.4% (95%CI: 41.89-48.85). Factors associated with hypertension were: neighborhood security (distal), age, economic class, education, and physical inactivity (intermediate), and body mass index (proximal). Health promotion is needed in the quilombo communities through action at the individual and population levels. The high prevalence of hypertension highlights the need for broad access to health services for prevention, early diagnosis, and guidelines for adequate management.

    The prevalence of hypertensive disorders in China was much higher than that in the United States. Considering the large population with wide geographic area of China, we aimed to add more information regarding the risk factors for hypertensive disorders of pregnancy. A case-control study was performed on 373 hypertensive cases and 507 normotensive controls. Participants were recruited from 2008 to 2014 in Yichang Maternal and Child Health Care Center in Hubei province and Anyang Maternal and Child Health Care Hospital in Henan province, China. Socio-demographic factors, family- related factors, pregnancy-associated factors, factors related to daily life behaviors and psychosocial factors were investigated with respect to hypertensive disorders in pregnancy through well-designed questionnaire. Chi-square test, t-test, univariate logistic regression analysis, and multivariate logistic regression analysis were used to find the possible risk factors behind hypertensive disorders in pregnancy. The results showed that family history of cardiovascular diseases (OR=6.18, 95% CI, 2.37 to 16.14), history of pregnancy-induced hypertension (OR=16.64, 95% CI, 5.74 to 48.22), low maternal educational level (OR=2.81, 95% CI, 1.30 to 6.04), and poor relationship with their parents-in-law (OR=3.44, 95% CI, 1.55 to 7.59) had statistically significant associations with hypertensive disorders in pregnancy through multivariate logistic regression analysis. Increased maternal age, increased pre-pregnancy body mass index, living in rural area, low paternal education level, family history of hypertension, passive smoking one year before and/or in pregnancy, and poor sleeping quality were significantly associated with hypertensive disorders in pregnancy from univariate logistic regression analysis while the associations became uncertain when they were entered for multivariate logistic regression analysis. It was concluded that family history of cardiovascular diseases, history of pregnancy

    This study aimed to assess pre-hypertension and hypertension-related factors in 1,125 seven- to-14-year-old subjects enrolled in the public school system in Salvador, Bahia State, Brazil. Exposure variables, namely body mass index, waist circumference, gender, age, physical activity, environmental and housing status, family income, diet, schooling, and maternal age were analyzed by polytomous logistic regression, and the outcome variable was categorized as normal, pre-hypertensive, and hypertensive. Prevalence of high blood pressure was 14.1%, including the prevalence of both hypertension (4.8%) and pre-hypertension (9.3%). An association was shown between pre-hypertension and overweight (OR: 3.13; 95%CI: 1.75-5.57). Hypertension was associated with overweight (OR: 3.02; 95%CI: 1.45-6.28), female gender (OR: 2.49; 95%CI: 1.24-4.98), and high-risk eating patterns (OR: 1.93; 95%CI: 1.04-3.56). In short, prevalence of pre-hypertension and hypertension in children and adolescents was higher among girls and individuals with overweight and inadequate diet.

    Hypertension is the most common psychosomatic disorder affecting 972 million people worldwide being more prevalent in old age. The present survey of hypertensive patients fulfilling the standard diagnostic criteria of WHO/ISH (2004) is carried out in geriatric age group from the Saurashtra region of Gujarat in India to observe the dietary pattern and provocative factors. Total 120 patients of 50 to 80 years of age having systolic blood pressure >140 mm Hg and ≤180 mm Hg and diastolic blood pressure >90 mm Hg and ≤110 mm Hg irrespective of gender and religion were selected for the present study. They were interviewed for list of provocative factors enlisted in Ayurveda. As observed, the study supported the facts described in Ayurveda that dietary etiological factors, such as excess intake of Lavana (salty), Amla (sour), Katu (pungent), Tikshna, Ushna (hot), Vidahi (producing burning sensation), Viruddha (incompatible), Snigdha (unctuous), Abhishyandi (leading to obstruction), Madhura (sweet), Guru (heavy to digest) dietary articles, Ajirnashana (taking diet before complete digestion of previous meal), Adhyashana (repeated eating at short intervals), will vitiate Rakta dhatu as well as Pitta dosha in the body leading to disorders like hypertension. Hypertension in old age is found to be a disease of Vata-Pitta dominant vitiation with the involvement of Rasa, Rakta, Meda as main Dushya (vitiated factors) and dietary factors can contribute to worsening of the disease. The etiological factors having role in the pathogenesis can also be applied for preventive guidelines for the management of hypertension.

    A cross-sectional study was carried out to determine the prevalence of hypertension in the Chinese elderly and to examine its relationship with various behavioural and nutritional risk factors. This study involved 243 Chinese aged 55 years and older in 2 randomly selected Chinese Villages in Seberang Prai Tengah, Penang. The study included an interview, anthropometric assessment and blood pressure measurement. The prevalence of hypertension was 48.1% and out of this, 65 (55.6%) were on anti-hypertensive treatment. There was a significant rise in the prevalence with age. Hypertension was found to be inversely related to per capita income and physical activity (p < 0.05). Hypertension was significantly more common in smokers than non-smokers. Alcohol intake in the elderly was low and not related to hypertension. Obesity was significantly associated with hypertension only among the elderly aged 55-64 years. The dietary intake of sodium, potassium and calcium did not differ significantly between the hypertensive and normotensive elderly.

    Full Text Available Aim: Hypertension, obesity, insulin resistance and lipid levels are risk factors for cardiovascular disease. The association of cardiovascular risk with C-reactive protein and homocysteine has been debated for decades. Resistin and microalbuminuria are presumed to be associated with diabetes mellitus, insulin resistance and cardiovascular disease. The objective of our study was to investigate the relationship of microalbuminuria with antropometric and metabolic parameters, C-reactive protein, homocyteine and resistin in non-diabetic hypertensive females. Methods: We conducted a randomized study including 37 female non-diabetic hypertensives without microalbuminuria and 47 female non-diabetic hypertensive patients with microalbuminuria. We made comparisons of anthropometric and metabolic parameters, C-reactive protein, homocysteine, insulin resistance index and resistin between the groups. Results: C-reactive protein, homocysteine, resistin, insulin levels and homeostasis model assessment of insulin resistance were higher in hypertensives with microalbuminuria than in hypertensives without microalbuminuria (all p<0.05. Conclusion: We found that microalbuminuria may have an influence on C-reactive protein, homocysteine and resistin levels in non-diabetic hypertensives. We also think that insulin and insulin resistance may also be related with microalbuminuria in non-diabetic hypertensive female patients. (The Me­di­cal Bul­le­tin of Ha­se­ki 2014; 52: 172-6

    Full Text Available Introduction. The prevalence of hypertension in Africa ranges from 29.7% in Cameroon to 47% in South Africa. Only 10% receive treatment in Cameroon while 32% are on medications in Ghana. Control rates vary from 0.4% to 16.8%. This study was done to assess prevalence, risk factors, awareness, treatment, and control of hypertension in Mafia Island, Tanzania, which has never been documented before, so that necessary interventions can be undertaken accordingly. Methodology. Data was collected through questionnaires and anthropometric measurements were taken. Descriptive statistics were done and potential correlations were analyzed. Results. Out of 570 adults who were included in the study, 154 (27% were aged 41–50 and the male-to-female ratio was 1 : 1.05. Almost half (49.5% of the participants fit into the criteria of hypertension. Out of the 118 participants who were aware of having hypertension, 68 (57.6% were currently taking medication. From those taking medication, only 14 (20.6% had controlled hypertension. Conclusion. This study tried to show the extent of hypertension and find out risk factors which could explain the high prevalence of hypertension. This is very alarming and a dire need to raise awareness through health education, availability of screening, and treating and follow-up should be given priority.

    Full Text Available Background. Idiopathic intracranial hypertension (IIH mostly affects young obese women and can lead to permanent visual impairment. However, prognostic factors and therapeutic strategy remain unclear. Methods. We retrospectively collected data from all patients diagnosed and managed for IIH in our university center from January 2001 to December 2016. Results. Seventy-nine patients were diagnosed with IIH. Bilateral transverse sinus stenosis (TSS was found in 74% of the population. Visual outcome at 6 months was poor for 46% of patients, including all patients presenting weight gain of at least 5% since diagnosis (p<0.001, whereas mean body mass index at diagnosis was not different between patients with poor versus good outcome (32.9±7.7 versus 34.6 ± 9.4 kg·m−2. Other significant factors of poor prognosis were bilateral TSS (OR = 5.2; 95 CI: 1.24–24.9; p=0.024. Thirteen patients with poor outcome after 6-month assessment underwent unilateral TSS stenting leading to visual improvement in 11 cases. Conclusion. Weight gain, rather than initial weight, emerged as the leading factor of poor visual outcome in patients with IIH, followed by presence of bilateral TSS. Consequently, first-line treatment must include dietary measures to control weight. Unilateral stenting appears to be a safe second-line treatment option for patients with bilateral TSS.

    Preeclampsia is a pregnancy-specific disorder of new-onset hypertension. Unfortunately, the most effective treatment is early delivery of the fetus and placenta. Placental ischemia appears central to the pathogenesis of preeclampsia because placental ischemia/hypoxia induced in animals by reduced uterine perfusion pressure (RUPP) or in humans stimulates release of hypertensive placental factors into the maternal circulation. The anti-angiogenic factor soluble fms-like tyrosine kinase-1 (sFlt-1), which antagonizes and reduces bioavailable vascular endothelial growth factor and placental growth factor (PlGF), is elevated in RUPP rats and preeclampsia. Although PlGF and vascular endothelial growth factor are both natural ligands for sFlt-1, vascular endothelial growth factor also has high affinity to VEGFR2 (Flk-1) causing side effects like edema. PlGF is specific for sFlt-1. We tested the hypothesis that PlGF treatment reduces placental ischemia-induced hypertension by antagonizing sFlt-1 without adverse consequences to the mother or fetus. On gestational day 14, rats were randomized to 4 groups: normal pregnant or RUPP±infusion of recombinant human PlGF (180 μg/kg per day; AG31, a purified, recombinant human form of PlGF) for 5 days via intraperitoneal osmotic minipumps. On day 19, mean arterial blood pressure and plasma sFlt-1 were higher and glomerular filtration rate lower in RUPP than normal pregnant rats. Infusion of recombinant human PlGF abolished these changes seen with RUPP along with reducing oxidative stress. These data indicate that the increased sFlt-1 and reduced PlGF resulting from placental ischemia contribute to maternal hypertension. Our novel finding that recombinant human PlGF abolishes placental ischemia-induced hypertension, without major adverse consequences, suggests a strong therapeutic potential for this growth factor in preeclampsia.

    Objective:To study the role of diabetes, hypertension and obesity in etiology of endometrial polyps. Methods: A total of 250 patients with endometrial polyp and 256 patients normal endometrial cavity were included, who applied to our outpatient clinic. We recorded the age, fertility state, body mass index, number of polyps, hypertension and diabetes status of the patients by using SPSS Windows 16.0. All patients in polyp group were verified by post-operative pathology report. Results:No significant difference was found in patients with diabetes and obesity, but hypertension was a significant factor in patients who had endometrial polyp comparing to total patient population (n=526). Conclusions:This finding may alert the physician to consider the endometrial cavity in hypertensive patients who applied with abnormal uterine bleeding.

    Full Text Available OBJECTIVE: To assess the determinants of the lack of pharmacological treatment for hypertension. METHODS: In 2005, 3,323 Mozambicans aged 25-64 years old were evaluated. Blood pressure, weight, height and smoking status were assessed following the Stepwise Approach to Chronic Disease Risk Factor Surveillance. Hypertensives (systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg and/or antihypertensive drug therapy were evaluated for awareness of their condition, pharmacological and non-pharmacological management, as well as use of herbal or traditional remedies. Prevalence ratios (PR were calculated, adjusted for sociodemographic characteristics, cardiovascular risk factors and non-pharmacological treatment. RESULTS: Most of the hypertensive subjects (92.3%, and nearly half of those aware of their condition were not treated pharmacologically. Among the aware, the prevalence of untreated hypertension was higher in men {PR = 1.61; 95% confidence interval (95%CI 1.10;2.36} and was lower in subjects under non-pharmacological treatment (PR = 0.58; 95%CI 0.42;0.79; there was no significant association with traditional treatments (PR = 0.75; 95%CI 0.44;1.26. CONCLUSIONS: The lack of pharmacological treatment for hypertension was more frequent in men, and was not influenced by the presence of other cardiovascular risk factors; it could not be explained by the use of alternative treatments as herbal/traditional medicines or non-pharmacological management. It is important to understand the reasons behind the lack of management of diagnosed hypertension and to implement appropriate corrective actions to reduce the gap in the access to healthcare between developed and developing countries.

    Full Text Available Antiretroviral therapy scale-up in Sub-Saharan Africa has created a growing, aging HIV-positive population at risk for non-communicable diseases such as hypertension. However, the prevalence and risk factors for hypertension in this population remain incompletely understood.We measured blood pressure and collected demographic data on over 65,000 adults attending multi-disease community health campaigns in 20 rural Ugandan communities (SEARCH Study: NCT01864603. Our objectives were to determine (i whether HIV is an independent risk factor for hypertension, and (ii awareness and control of hypertension in HIV-positive adults and the overall population.Hypertension prevalence was 14% overall, and 11% among HIV-positive individuals. 79% of patients were previously undiagnosed, 85% were not taking medication, and 50% of patients on medication had uncontrolled blood pressure. Multivariate predictors of hypertension included older age, male gender, higher BMI, lack of education, alcohol use, and residence in Eastern Uganda. HIV-negative status was independently associated with higher odds of hypertension (OR 1.2, 95% CI: 1.1-1.4. Viral suppression of HIV did not significantly predict hypertension among HIV-positives.The burden of hypertension is substantial and inadequately controlled, both in HIV-positive persons and overall.

    Resistant hypertension, defined as blood pressure >140/90 mm Hg despite using ≥3 antihypertensive medications, is a well-recognized clinical entity. Patients with resistant hypertension are at an increased risk of cardiovascular disease compared with those with more easily controlled hypertension. Coronary heart disease mortality rates of younger adults are stagnating or on the rise. The purpose of our study was to characterize the phenotype and risk factors of younger patients with resistant hypertension, given the dearth of data on cardiovascular risk profile in this cohort. We conducted a cross-sectional analysis with predefined age groups of a large, ethnically diverse cohort of 2170 patients referred to the Hypertension Clinic at the University of Alabama at Birmingham. Patients (n=2068) met the inclusion criteria and were classified by age groups, that is, ≤40 years (12.7% of total cohort), 41 to 55 years (32.1%), 56 to 70 years (36.1%), and ≥71 years (19.1%). Patients aged ≤40 years compared with those aged ≥71 years had significantly earlier onset of hypertension (24.7±7.4 versus 55.0±14.1 years; Phypertension, younger individuals have a distinct phenotype characterized by overlapping risk factors and comorbidities, including obesity, high aldosterone, and high dietary sodium intake compared with elderly. © 2017 American Heart Association, Inc.

    The age at diagnosis of pulmonary arterial hypertension (PAH) and the prevalence of cardiovascular (CV) risk factors are increasing. We sought to determine whether the response to drug therapy was influenced by CV risk factors in PAH patients. We studied consecutive incident PAH patients (n = 146) between January 1, 2008, and July 15, 2011. Patients were divided into two groups: the PAH-No CV group included patients with no CV risk factors (obesity, systemic hypertension, type 2 diabetes mellitus, permanent atrial fibrillation, mitral and/or aortic valve disease, and coronary artery disease), and the PAH-CV group included patients with at least one. The response to PAH treatment was analyzed in all the patients who received PAH drug therapy. The PAH-No CV group included 43 patients, and the PAH-CV group included 69 patients. Patients in the PAH-No CV group were younger than those in the PAH-CV group (P < 0.0001). In the PAH-No CV group, 16 patients (37%) improved on treatment and 27 (63%) did not improve, compared with 11 (16%) and 58 (84%) in the PAH-CV group, respectively (P = 0.027 after adjustment for age). There was no difference in survival at 30 months (P = 0.218). In conclusion, in addition to older age, CV risk factors may predict a reduced response to PAH drug therapy in patients with PAH.

    Background. The etiology of the high prevalence of hypertension among patients with hemophilia (PWH) remains unknown. Methods. We compared 469 PWH in the United States with males from the National Health and Nutrition Examination Survey (NHANES) to determine whether differences in cardiovascular risk factors can account for the hypertension in hemophilia. Results. Median systolic and diastolic BP were higher in PWH than NHANES (P hemophilia. New investigations into the missing link between hemophilia and hypertension should include age of onset of hypertension and hemophilia-specific morbidities such as the role of inflammatory joint disease.

    2010-03-01

    Normal pregnancy is associated with significant vascular remodeling in the uterine and systemic circulation in order to meet the metabolic demands of the mother and developing fetus. The pregnancy-associated vascular changes are largely due to alterations in the amount/activity of vascular mediators released from the endothelium, vascular smooth muscle and extracellular matrix. The endothelium releases vasodilator substances such as nitric oxide, prostacyclin and hyperpolarizing factor as well as vasoconstrictor factors such as endothelin, angiotensin II and thromboxane A(2). Vascular smooth muscle contraction is mediated by intracellular free Ca(2+) concentration ([Ca(2+)](i)), and [Ca(2+)](i) sensitization pathways such as protein kinase C, Rho-kinase and mitogen-activated protein kinase. Extracellular matrix and vascular remodeling are regulated by matrix metalloproteases. Hypertension in pregnancy and preeclampsia are major complications and life threatening conditions to both the mother and fetus, precipitated by various genetic, dietary and environmental factors. The initiating mechanism of preeclampsia and hypertension in pregnancy is unclear; however, most studies have implicated inadequate invasion of cytotrophoblasts into the uterine artery, leading to reduction in the uteroplacental perfusion pressure and placental ischemia/hypoxia. This placental hypoxic state is thought to induce the release of several circulating bioactive factors such as growth factor inhibitors, anti-angiogenic proteins, inflammatory cytokines, reactive oxygen species, hypoxia-inducible factors, and vascular receptor antibodies. Increases in the plasma levels and vascular content of these factors during pregnancy could cause an imbalance in the vascular mediators released from the endothelium, smooth muscle and extracellular matrix, and lead to severe vasoconstriction and hypertension. This review will discuss the interactions between the various circulating bioactive factors and

    Disorders of carbohydrate and lipid metabolism have been reported to cluster in patients with essential hypertension and in spontaneously hypertensive rats (SHRs). A deletion in the Cd36 gene on chromosome 4 has recently been implicated in defective carbohydrate and lipid metabolism in isolated adipocytes from SHRs. However, the role of Cd36 and chromosome 4 in the control of blood pressure and systemic cardiovascular risk factors in SHRs is unknown. In the SHR. BN-Il6/Npy congenic strain, we have found that transfer of a segment of chromosome 4 (including Cd36) from the Brown Norway (BN) rat onto the SHR background induces reductions in blood pressure and ameliorates dietary-induced glucose intolerance, hyperinsulinemia, and hypertriglyceridemia. These results demonstrate that a single chromosome region can influence a broad spectrum of cardiovascular risk factors involved in the hypertension metabolic syndrome. However, analysis of Cd36 genotypes in the SHR and stroke-prone SHR strains indicates that the deletion variant of Cd36 was not critical to the initial selection for hypertension in the SHR model. Thus, the ability of chromosome 4 to influence multiple cardiovascular risk factors, including hypertension, may depend on linkage of Cd36 to other genes trapped within the differential segment of the SHR. BN-Il6/Npy strain.

    Full Text Available Almost everyone, including employees, may develop hypertension. Several risk factors, including stresses in the work environment, are related to hypertension. The aim of this study is to identify these work-related risk factors in hypertension. A nested case-control study was conducted among office employees in Jakarta during May 2004. Employees with stage 1 or stage 2 hypertension (based on the United States of America Joint National Committee on high blood pressure 2003, or those taking antihypertensive drugs were designated as cases. As controls were employees with no history of hypertension. One case was randomly matched by gender with two controls. All risk factors for cases and controls were counted as of the reference date of diagnosis for cases. There were 70 cases and 140 controls aged 25 to 65 years. Hypertension was found to be related to the qualitative and quantitative increase in the workload, career development, age, obesity, current and past smoking habits, and a family history of hypertension. However, it was noted that role of ambiguity, role of conflict, and personal responsibility did not increase the risk of hypertension. Compared to those with low qualitative job stressor, those who had moderate or high qualitative job stressor had a seven-fold risk to be hypertensive [adjusted odds ratio (ORa = 7.47; 95% confidence interval (CI = 1.40-39.76]. In addition, relative to those who had low quantitative job stressor, those with moderate or high stressors were four times at risk to be hypertensive (ORa = 4.10; 95% CI = 1.06-15.90. In conclusion moderate or high qualitative and quantitative job stressors as well as career development increased risk hypertension. Therefore these stressors need to be prevented.

    Full Text Available This study aimed to seek the evidence available in the literature regarding the factors related to adherence to treatment for systemic hypertension. It used the method of integrative review in the databases MEDLINE, CINAHL, and LILACS, using the keywords: hypertension, compliance, non-compliance, adherence, non-adherence, patient compliance, in the period 2004 – 2008, and articles in Portuguese, English and Spanish, with the use of a validated instrument and content analysis. 28 studies were selected, 64.3% of which had level of evidence VI. The following were identified as factors related to adherence to treatment: treatment costs, educational activities, sex, physician-patient relationship, physiological and behavioral aspects, drug therapy, attending checkups and lifestyle. The use of combined strategies is suggested in order to increase the individuals’ adherence to the treatment. Gaps point to the valorization of dialogic relationships for integrated and more efficacious health practices.

    Full Text Available Abstract Background The prevalence of hypertension is increasing in much of the South Asian region, including Nepal. This paper reports the prevalence and risk factors of hypertension and pre-hypertension among adult women in a rural community of Nepal. Methods Cross-sectional data on socioeconomic status (SES, lifestyle factors and blood pressure (BP were collected from a cohort of 15,934 women in rural Nepal in 2006–08. Among a subsample (n = 1679, anthropometry and biomarkers of cardiovascular risk were measured. Results The mean age of women was 34.2 years (range 16.4-71.2 years. More than three percent (3.3% had hypertension and 14.4% had pre-hypertension. In an adjusted analysis, lower SES, especially lower household farm assets and storage of food for long term consumption, was associated with increased odds of hypertension (OR = 1.14 for mid-level SES and OR = 1.40 for low SES; p for trend  Conclusions Although the prevalence of hypertension was low in this cohort, it was more prevalent among the poorer women and was strongly associated with other cardiovascular risks. These associations at a relatively young age may confer greater risk for cardiovascular disease among women in later life, indicating the need for interventions to reduce the progression from pre-hypertension to hypertension.

    Many US adults have multiple chronic conditions, and hypertension and diabetes are among the most common dyads. Diabetes and prediabetes prevalence are increasing, and both conditions negatively affect cardiovascular health. Early diagnosis and treatment of diabetes and prediabetes can benefit people with hypertension by preventing cardiovascular complications. We analyzed 2011 Minnesota Behavioral Risk Factor Surveillance System data to describe the proportion of adults with hypertension screened for diabetes according to US Preventive Services Task Force Recommendations for blood glucose testing. Covariates associated with lower odds of recent screening among adults without diabetes were determined using weighted logistic regression. Of Minnesota adults with self-reported hypertension, 19.6% had a diagnosis of diabetes and 10.7% had a diagnosis of prediabetes. Nearly one-third of adults with hypertension without diabetes had not received blood glucose screening in the past 3 years. Factors associated with greater odds of not being screened in multivariable models included being aged 18 to 44 years (adjusted odds ratio [AOR], 1.77; 95% confidence interval [CI], 1.23-2.55); being nonobese, with stronger effects for normal body mass index; having no check-up in the past 2 years (AOR, 2.49; 95% CI, 1.49-4.17); having hypertension treated with medication (AOR, 2.01; 95% CI, 1.49-2.71); and completing less than a college degree (AOR, 1.45; 95% CI, 1.14-1.84). Excluding respondents with prediabetes or those not receiving a check-up did not change the results. Failure to screen among providers and failure to understand the importance of screening among individuals with hypertension may mean missed opportunities for early detection, clinical management, and prevention of diabetes.

    Methods. Cross-sectional community-based study using the WHO stepwise approach. Saudi adults were randomly chosen from Primary Health Care Centers catchment areas. Data was collected using a questionnaire which included sociodemographic data, history of hypertension, risk factors, treatment practices, biochemical and anthropometric measurements. Collected data was cheeked, computer fed, and analysed using SPSS V17. Results. Out of 4719 subjects (99.2% response, 542 (11.5% subjects were known hypertensives or detected by health workers in the past 12 months. Hypertension was significantly associated with age, gender, geographical location, education, employment, diabetes, physical inactivity, excess body weight, and ever smoking. Multiple logistic analysis controlling for age showed that significant predictors of hypertension were diabetes mellitus, ever smoking, obesity, and hypercholesteremia. Several treatment modalities and practices were significantly associated with gender, age, education, and occupation. About 74% were under prescribed treatment by physicians, 62% on dietary modification, 37% attempted weight reduction, 27% performed physical exercise, and less than 7% used herbs, consulted traditional healers or quitted smoking. Income was not significantly associated with any treatment modality or patient practices. Conclusion. Hypertension (known and undetected is a major chronic health problem among adults in Saudi Arabia. Many patients' practices need changes. A comprehensive approach is needed to prevent, early detect, and control the disease targeting, the risk factors, and predictors identified.

    Activated proteinC resistance is a frequent prothrombotic abnormality. In most cases it is due to factorV Leiden mutation by nucleotide G1691A substitution. This recently described thrombophilic defect of activated proteinC resistance has been postulated to be implicated in the pathogenesis of idiopathic intracranial hypertension (IIH). We report a case of factorV Leiden mutation in association with IIH and their likely link and implication in the management of IIH. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Full Text Available Background: Since the data of primary hypertension (HT in children is scanty in India, this study attempted to evaluate HT by a multidimensional investigation of the various risk factors in children and adolescents. Materials and Methods: A total of 3906 subjects were recruited, all of whom lived in Chennai, an urban area of Tamil Nadu. The children and adolescents aged from 10 to 17 years were selected by random sampling. The children/adolescents were randomized into one control and further divided into two groups. The National High Blood Pressure Education Program fourth report (2004 and anthropometric body mass index (BMI, food frequency questionnaire (PURE were followed in the study. Results: Out of 3906 children, 2107 were girls and 1799 boys. On screening, we found 9.5% to be hypertensive with the prevalence rate of boys and girls 8% and 10.8%, respectively. Overall obesity was 2.7%, (boys 2%, girls 3.32%; hypertensives and normotensives were 8.4% and 2.1%, respectively. We found that overweight (odds ratio [OR]: 2.06 [1.40-3.01] 95% confidence interval [CI], obese children (OR: 1.21 [2.72-6.48] 95% CI, and those with a family history of HT (OR: 1.66 [1.20-2.30] 95% CI had increased risk of hypertension. Females were 1.39 times (OR: 1.39 [1.11-1.72] 95% CI more at risk of getting HT. Multivariate analysis showed that obese children/adolescent were four times more likely to have HT than children with normal BMI (OR: 4.67 [3.00-7.26] 95% CI]. Conclusion: Family history of HT, obesity, and female gender are associated with a high risk of HT. The prevalence of HT was higher among obese adolescents than among slender subjects. This may be related to their sedentary lifestyle, faulty eating habits, high fat content in the diet and little physical activity.

    Many hypertensive patients are not treated to target and hence do not benefit fully from the blood pressure-related improvements in cardiovascular health. Hypertensive patients who had primarily been treated to a target goal in a nurse-led hypertension clinic were re-examined to evaluate whether their target goal blood pressure was maintained after their discharge from the hypertension clinic for further control in primary care, and to evaluate potential barriers to and factors acting against continuous hypertension control. The median observation time was 3.6 years (range 3 months to 7.9 years). Only 45.2% of the patients were well controlled at the time of re-examination. No patient-related factors (age, body mass index, gender, attitudes towards medication) predicted the outcome. Two factors were significant in the reduction in continuous hypertension control: the cooperation between the patient and health personnel and the shared commitment towards the target goal were discontinued; and many patients did not make control visits to the general practitioner's office. In conclusion, maintained strict control of hypertension requires both continued close collaboration between the patient and health personnel, with an emphasis on treatment goals, and systematic control visits.

    Full Text Available Hypertension, once a rare problem in Sub-Saharan Africa (SSA, is predicted to be a major cause of death by 2020 with mortality rates as high as 75%. However, comprehensive knowledge of provider-level factors that influence optimal management is limited. The objective of the current study was to discover physicians’ perceptions of factors influencing optimal management and control of hypertension in SSA. Twelve physicians attending the Cardiovascular Research Training (CaRT Institute at the University of Ghana, College of Health Sciences, were invited to complete a concept mapping process that included brainstorming the factors influencing optimal management and control of hypertension in patients, sorting and organizing the factors into similar domains, and rating the importance and feasibility of efforts to address these factors. The highest ranked important and feasible factors include helping patients accept their condition and availability of adequate equipment to enable the provision of needed care. The findings suggest that patient self-efficacy and support, physician-related factors, policy factors, and economic factors are important aspects that must be addressed to achieve optimal hypertension management. Given the work demands identified by physicians, future research should investigate cost-effective strategies of shifting physician responsibilities to well-trained no-physician clinicians in order to improve hypertension management.

    Full Text Available Abstract Background Certain conditions characterised by blood vessel occlusion or vascular spasm have been found to cluster together in epidemiological studies. However the biological causes for these associations remain controversial. This study used a classical twin design to examine whether these conditions are linked through shared environmental exposures or by a common underlying genetic propensity to vasospasm. Methods We investigated the association between hypertension, migraine, Raynaud's phenomenon and coronary artery disease in twins from a national register. Phenotype status was determined using a questionnaire and the genetic and environmental association between phenotypes was estimated through variance components analysis. Results Responses were obtained from 2,204 individuals comprising 525 monozygotic and 577 dizygotic pairs. There was a significant genetic contribution to all four traits with heritabilities ranging from 0.34 to 0.64. Multivariate model-fitting demonstrated that a single common genetic factor underlies the four conditions. Conclusions We have confirmed an association between hypertension, migraine, Raynaud's phenomenon and coronary artery disease, and shown that a single genetic factor underlies them. The demonstration of a shared genetic factor explains the association between them and adds weight to the theory of an inherited predisposition to vasospasm.

    The association of female reproductive factors (FRFs) with cardiovascular risk factors among different population was variable and inconsistent. The objective of this study was to examine the association between FRFs and hypertension, type 2 diabetes mellitus (DM), and long heart-rate-corrected QT interval (LQTc) in Chinese post-menopausal women (Post-MW). A total of 8046 Post-MW from the China Chaoshan Biobank Cohort Study were included for analysis. Logistic regression and general linear regression models were used to estimate the association between FRFs and hypertension, DM, and LQTc. Compared with women with 0 or 1 live birth, increasing risk of hypertension (odds ratio [OR], 1.51; 95% confidence interval [CI], 1.16–1.96), DM (OR, 1.65; 95% CI, 1.22–2.22), and LQTc (OR, 1.45; 95% CI, 1.01–2.09) were observed in women who had five or more live births. Further analysis demonstrated that the association between parity and hypertension, DM, and LQTc was mediated by lifestyle and dyslipidemia. Women with more live births had increased body mass index and waist circumstance, and were inclined to consume more salty food, animal fat, and alcohol, but less meat, vegetable, fish, plant oil, and tea, compared with that had fewer live births (all P < 0.05).

    Prehypertension is associated with increased risk for hypertension and cardiovascular disease. Data are limited on the temporal changes in the prevalence of prehypertension and risk factors for hypertension and cardiovascular disease among US adults with prehypertension. We analyzed data from 30 958 US adults ≥20 years of age who participated in the National Health and Nutrition Examination Surveys between 1999 and 2012. Using the mean of 3 blood pressure (BP) measurements from a study examination, prehypertension was defined as systolic BP of 120 to 139 mm Hg and diastolic BP adults with prehypertension decreased from 31.2% to 28.2% (P trend=0.007). During this time period, the prevalence of several risk factors for cardiovascular disease and incident hypertension increased among US adults with prehypertension, including prediabetes (9.6% to 21.6%), diabetes mellitus (6.0% to 8.5%), overweight (33.5% to 37.3%), and obesity (30.6% to 35.2%). There was a nonstatistically significant increase in no weekly leisure-time physical activity (40.0% to 43.9%). Also, the prevalence of adhering to the Dietary Approaches to Stop Hypertension eating pattern decreased (18.4% to 11.9%). In contrast, there was a nonstatistically significant decline in current smoking (25.9% to 23.2%). In conclusion, the prevalence of prehypertension has decreased modestly since 1999-2000. Population-level approaches directed at adults with prehypertension are needed to improve risk factors to prevent hypertension and cardiovascular disease. © 2017 American Heart Association, Inc.

    Full Text Available Aim. Hypertension is one of the major risk factors for atherosclerosis. Adiponectin is mainly synthesized by white adipose tissue; it is known to have anti-atherogenic and anti-inflammatory effects on endothelial cells and macrophages. Methods. A total of 80 individuals including 48 hypertensive and 32 normotensive individuals were included in the study. Groups were separated as obese and non-obese. Results. It was found out that the patient group had statistically higher systolic blood pressure, diastolic blood pressure, fasting plasma glucose, total cholesterol, triglyceride, low density lipoprotein, high sensitive C reactive protein and microalbuminuria values than the control group while high density lipoprotein values were significantly lower (p<0.05. When adiponectin levels of the groups were compared, the patient group had an adiponectin level of 8.66±2.75 µg/mL and the control group had an adiponectin level of 15.01±3.99 µg/mL. There was a statistically significant difference between two groups (p<0.05. There was a negative correlation between adiponectin level and atherosclerotic risk factors. Conclusion. Adiponectin level was lower in hypertensive group when compared to the control group; there was also a significant association between adiponectin and atherosclerotic risk factors. A low adiponectin level constitutes an important risk for development of atherosclerosis.

  2. Abnormal cardiovascular response to exercise in hypertension: contribution of neural factors.

    Science.gov (United States)

    Mitchell, Jere H

    2017-06-01

    During both dynamic (e.g., endurance) and static (e.g., strength) exercise there are exaggerated cardiovascular responses in hypertension. This includes greater increases in blood pressure, heart rate, and efferent sympathetic nerve activity than in normal controls. Two of the known neural factors that contribute to this abnormal cardiovascular response are the exercise pressor reflex (EPR) and functional sympatholysis. The EPR originates in contracting skeletal muscle and reflexly increases sympathetic efferent nerve activity to the heart and blood vessels as well as decreases parasympathetic efferent nerve activity to the heart. These changes in autonomic nerve activity cause an increase in blood pressure, heart rate, left ventricular contractility, and vasoconstriction in the arterial tree. However, arterial vessels in the contracting skeletal muscle have a markedly diminished vasoconstrictor response. The markedly diminished vasoconstriction in contracting skeletal muscle has been termed functional sympatholysis. It has been shown in hypertension that there is an enhanced EPR, including both its mechanoreflex and metaboreflex components, and an impaired functional sympatholysis. These conditions set up a positive feedback or vicious cycle situation that causes a progressively greater decrease in the blood flow to the exercising muscle. Thus these two neural mechanisms contribute significantly to the abnormal cardiovascular response to exercise in hypertension. In addition, exercise training in hypertension decreases the enhanced EPR, including both mechanoreflex and metaboreflex function, and improves the impaired functional sympatholysis. These two changes, caused by exercise training, improve the muscle blood flow to exercising muscle and cause a more normal cardiovascular response to exercise in hypertension.

    Preeclampsia, a prevalent hypertensive disorder of pregnancy, is believed to be secondary to uteroplacental ischemia. Accumulating evidence indicates that hypoxia-independent mediators, including inflammatory cytokines and growth factors, are associated with preeclampsia, but it is unclear whether these signals directly contribute to placental damage and disease development in vivo. We report that LIGHT, a novel tumor necrosis factor superfamily member, is significantly elevated in the circulation and placentas of preeclamptic women compared with normotensive pregnant women. Injection of LIGHT into pregnant mice induced placental apoptosis, small fetuses, and key features of preeclampsia, hypertension and proteinuria. Mechanistically, using neutralizing antibodies specific for LIGHT receptors, we found that LIGHT receptors herpes virus entry mediator and lymphotoxin β receptor are required for LIGHT-induced placental impairment, small fetuses, and preeclampsia features in pregnant mice. Accordingly, we further revealed that LIGHT functions through these 2 receptors to induce secretion of soluble fms-like tyrosine kinase-1 and endothelin-1, 2 well-accepted pathogenic factors in preeclampsia, and thereby plays an important role in hypertension and proteinuria in pregnant mice. Lastly, we extended our animal findings to human studies and demonstrated that activation of LIGHT receptors resulted in increased apoptosis and elevation of soluble fms-like tyrosine kinase-1 secretion in human placental villous explants. Overall, our human and mouse studies show that LIGHT signaling is a previously unrecognized pathway responsible for placental apoptosis, elevated secretion of vasoactive factors, and subsequent maternal features of preeclampsia, and reveal new therapeutic opportunities for the management of the disease.

    Full Text Available PURPOSE: This study aimed to assess the prevalence, awareness, treatment, and control of hypertension and their associated factors among Bai ethnic population in the rural China. METHODS: A population-based survey was conducted in 2010 with a randomly cluster sampling in rural communities in Dali, southwest China. A total of 2133 adults aged 50 or above were interviewed, and their blood pressure, height, weight and waist circumference were measured. Hypertension was defined as a mean SBP≥140 mmHg and/or DBP≥90 mmHg, and/or current use of antihypertensive medications. RESULTS: The prevalence of hypertension was 42.1% (899/2133, and the age- and gender-adjusted prevalence was 40.0%. Among the hypertensive participants, 28.4% (255/899were aware of their condition, while 24.6% (221/899 took antihypertensive medications, with only 7.5% (67/899 of those achieving blood pressure control (<140/90 mmHg. Risk factors for hypertension were older age, smoking, alcohol drinking, family history of HBP, overweight, and obesity, while protective factors included being lean, and having finished senior high school or above. CONCLUSIONS: Hypertension prevalence is high among the population of Bai ethnic group in China, while the associated risk factors of hypertension include overweight/obesity, cigarette smoking, history of hypertension, and older age. The percentages of hypertensive participants aware of their hypertension and those taking antihypertensive medications were low with an incredibly low proportion of hypertensive patients who kept their hypertension under control. It is suggested that health education and hypertension screening programs be carried out in the area for the high blood pressure prevention and control.

    Objective: Existing literature shows considerable regional differences in terms of hypertension (HT) prevalence in Turkey. The purpose of this study was to analyze some of the known HT risk factors contributing to the variations between urban and rural areas of Turkey in HT development. Methods: We used data from the 2011 Chronic Diseases and Risk Factors Survey that was conducted by the Turkish Ministry of Health on a representative sample of the Turkish adult population aged 20 years or more (n=16.227). HT was defined as having at least one of the following: a mean systolic/diastolic blood pressure of at least 140/90 mm Hg, a previously diagnosed disease, or use of antihypertensive medication. Stepwise multiple logistic regression analysis was used to estimate HT risk factors in urban and rural settings. Results: Although the HT prevalence was higher in rural areas (28.4%) than in urban areas (23.9%), in this study, urbanization was found to be a contributing factor in multivariate regression analysis. Furthermore, separate regressions for urban and rural settings revealed that age, obesity, diabetes, hyperlipidemia, and smoking were independently and positively associated (purban areas only. Conclusion: The findings of our study demonstrate that contributory factors show some variations between urban and rural settings, and on gender within each setting. Taking into account the variations between urban and rural areas in HT development may provide greater insight into the design of prevention strategies. PMID:28430114

    Full Text Available There is increased risk of cardiovascular disease among HIV seropositive individuals. The prevalence of HIV is highest in sub-Saharan Africa; however, HIV-related cardiovascular risk research is largely derived from developed country settings. Herein, we describe the prevalence of hypertension and obesity in a large HIV treatment program in Kenya.We performed a retrospective analysis of the electronic medical records of a large HIV treatment program in Western Kenya between 2006 and 2009. We calculated the prevalence of hypertension and obesity among HIV+ adults as well as utilized multiple logistic regression analyses to examine the relationship between clinical characteristics, HIV-related characteristics, and hypertension.Our final sample size was 12,194. The median systolic/diastolic blood pressures were similar for both sexes (male: 110/70 mmHg, female: 110/70 mmHg. The prevalence of hypertension among men and women were 11.2% and 7.4%, respectively. Eleven percent of men and 22.6% of women were overweight/obese (body mass index ≥25 kg/m(2. Ordinal logistic regression analyses showed that overweight/obesity was more strongly associated with hypertension among HIV+ men (OR 2.41, 95% CI 1.88-3.09 than a higher successive age category (OR 1.62, 95% CI 1.40-1.87 comparing 16-35, 36-45 and >45 years categories. Among women, higher age category and overweight/obesity were most strongly associated with hypertension (age category: OR 2.21, 95% CI 1.95-2.50, overweight/obesity: OR 1.80, 95% CI 1.50-2.16. Length of time on protease inhibitors was not found to be related to hypertension for men (OR 1.62, 95% CI 0.42-6.20 or women (OR 1.17, 95% CI 0.37-2.65 after adjustment for CD4 count, age and BMI.In Western Kenya, there is a high prevalence of hypertension and overweight/obesity among HIV+ patients with differences observed between men and women.

    Hypertension remains uncontrolled in more than 50% of treated patients. Barriers to hypertension control include those that are patient-related, physician-related, and related to the health system. Identification of uncontrolled hypertension, pseudoresistant hyper-tension, and resistant hypertension require thoughtful attention to accurate blood pressure measurement, lifestyle factors, evaluation for secondary causes of hypertension, and proper treatment. Recent guidelines emphasize the importance of aggressive treatment and referral to hypertension specialists for patients with resistant hypertension, defined as blood pressure that remains above goal despite the use of three appropriate anti-hypertensive agents.

    Refractory hypertension is an extreme phenotype of antihypertensive treatment failure. Participants in the REasons for Geographic And Racial Differences in Stroke (REGARDS) Study, a large (n=30 239), population-based cohort were evaluated to determine the prevalence of refractory hypertension and associated cardiovascular risk factors and comorbidities. Refractory hypertension was defined as uncontrolled blood pressure (systolic/diastolic, ≥140/90 mm Hg) on ≥5 antihypertensive drug classes. Participants with resistant hypertension (systolic/diastolic, ≥140/90 mm Hg on ≥3 or hypertension served as comparator groups. Of 14 809 REGARDS participants receiving antihypertensive treatment, 78 (0.5%) had refractory hypertension. The prevalence of refractory hypertension was 3.6% among participants with resistant hypertension (n=2144) and 41.7% among participants on ≥5 antihypertensive drug classes. Among all participants with hypertension, black race, male sex, living in the stroke belt or buckle, higher body mass index, lower heart rate, reduced estimated glomerular filtration rate, albuminuria, diabetes mellitus, and history of stroke and coronary heart disease were associated with refractory hypertension. Compared with resistant hypertension, prevalence ratios for refractory hypertension were increased for blacks (3.00; 95% confidence interval, 1.68-5.37) and those with albuminuria (2.22; 95% confidence interval, 1.40-3.52) and diabetes mellitus (2.09; 95% confidence interval, 1.32-3.31). The median 10-year Framingham risk for coronary heart disease and stroke was higher among participants with refractory hypertension when compared with those with either comparator group. These data indicate that although resistant hypertension is relatively common among treated patients with hypertension, true antihypertensive treatment failure is rare.

    In scleroderma patients, isolated pulmonary hypertension (PHT) has been associated with selected HLA haplotypes, severe impairment of the diffusing capacity for carbon monoxide and the diagnosis of CREST. Most patients with CREST have a late-age onset of the disease, corresponding to the perimenopausal or postmenopausal period. We conducted a retrospective cohort study to determine the role of post-menopause and of the other known clinical and biological markers in the development of isolated pulmonary hypertension in Italian patients with systemic sclerosis. 189 female patients with scleroderma who had no ecographic signs of pulmonary hypertension (PHT) and radiographic signs of lung fibrosis at the first visit and did not develop significant pulmonary fibrosis during the observation time were included. Sixty-three out of 189 patients (33.3%) presented isolated pulmonary hypertension. A severe impairment of diffusing capacity for carbon monoxide at admission was found to be an early predictive element for its development. An increased risk was associated with postmenopausal condition (RR = 5.2, p = 0.000), CREST syndrome (RR = 2.8, p = 0.001) and haplotype HLA-B35 (RR = 2.8; p = 0.002). A significant positive interaction between postmenopausal condition and either HLA-B35 (RR = 15.2; p = 0.000) or the diagnosis of CREST (RR = 14.1; p = 0.000) was found. Postmenopausal condition alone or in combination with HLA-B35 and CREST syndrome is the main risk-factor for developing primary pulmonary hypertension in scleroderma patients. This suggests that hormonal replacement therapy could play a role in preventing isolated PHT in patients with systemic sclerosis.

    Full Text Available INTRODUCTION: Studies disagree as to whether there is a greater prevalence of hypertension among HIV/AIDS patients and the role of antiretroviral therapy. OBJECTIVE: Evaluate the prevalence of hypertension and risk factors in a cohort of HIV-infected patients, with emphasis on antiretroviral therapy. METHOD: Case-control study conducted at baseline of a cohort, between June/2007 and December/2008 in Pernambuco/Brazil. Blood pressure was classified as normal, prehypertension, and hypertension. RESULTS: Of 958 patients, 245 (25.6% had hypertension (cases, 325 (33.9% had prehypertension, and 388 (40.5% were normotensive (controls. Comparison between hypertensive and normotensive patients showed that traditional factors, such as age > 40 (OR = 3.06, CI = 1.91-4.97, male gender (OR = 1.85, CI = 1.15-3.01, BMI > 25 (OR = 5.51, CI = 3.36-9.17, and triglycerides > 150 mg/dL (OR = 1.69, CI = 1.05-2.71, were independently associated with hypertension. Duration of antiretroviral therapy and CD4 > 200 cells/mm³ were associated with hypertension in univariate analysis, but did not remain in final model. Type of antiretroviral schema and lipodystrophy showed no association with hypertension. CONCLUSION: Hypertension in HIV/AIDS patients is partially linked to invariable factors, such as age and sex. Efforts should be directed toward controlling reversible factors, particularly excessive weight gain and unsuitable diet.

    Post-transplantation hypertension is very common and is associated with cardiovascular complications and poor graft survival in kidney transplant recipients. This study aimed to identify risk factors for hypertension after living donor kidney transplantation. We retrospectively analyzed patients who underwent renal transplantation between January 2009 and April 2012. Hypertension was defined as the use of antihypertensive medications at 12 months post-transplantation. Student t test and chi-squared test were performed for univariate analysis. Logistic regression analysis was performed for multivariate analysis. Five-hundred thirty-nine patients were enrolled in the analyses. The rate of antihypertensive medication use was 67% at 12 months. In multivariate analysis, male gender (odds ratio [OR], 2.68; 95% confidence interval [CI], 1.55-4.61), pretransplantation hypertension (OR, 4.65; 95% CI, 2.14-10.11), donor hypertension (OR, 3.23; 95% CI, 1.05-9.96), high body mass index (BMI; OR, 1.21; 95% CI, 1.12-1.29), and use of cyclosporine (OR, 2.05; 95% CI, 1.28-3.27) were associated with post-transplantation hypertension. These data show that male recipient, hypertension before transplantation, donor hypertension, high BMI, and cyclosporine use were independent factors associated with hypertension. It would be useful to predict and prevention the hypertension after kidney transplantation. Copyright © 2016 Elsevier Inc. All rights reserved.

    Refractory hypertension is an extreme phenotype of antihypertensive treatment failure. Participants in the REasons for Geographic And Racial Differences in Stroke (REGARDS) Study, a large (n=30,239), population-based cohort were evaluated to determine the prevalence of refractory hypertension and associated cardiovascular risk factors and comorbidities. Refractory hypertension was defined as uncontrolled blood pressure (systolic/diastolic ≥ 140/90 mm Hg) on ≥ 5 antihypertensive drug classes. Participants with resistant hypertension (systolic/diastolic ≥140/90 mm Hg on ≥ 3 orhypertensive participants served as comparator groups. Of 14,809 REGARDS participants receiving antihypertensive treatment, 78 (0.5%) had refractory hypertension. The prevalence of refractory hypertension was 3.6% among participants with resistant hypertension(n=2,144) and 41.7% among participants on 5 or more antihypertensive drug classes. Among all hypertensive participants, African American race, male gender, living in the stroke belt or buckle, higher body mass index, lower heart rate, reduced estimated glomerular filtration rate, albuminuria, diabetes and history of stroke and coronary heart disease were associated with refractory hypertension. Compared to resistant hypertension, prevalence ratios for refractory hypertension were increased for African Americans (3.00, 95% CI 1.68 – 5.37) and those with albuminuria (2.22, 95% CI 1.40 – 3.52) and diabetes (2.09, 95% CI 1.32 – 3.31). The median 10-year Framingham risk for coronary heart disease and stroke was higher among participants with refractory hypertension compared to either comparator group. These data indicate that while resistant hypertension is relatively common among treated hypertensive patients, true antihypertensive treatment failure is rare. PMID:24324035

    Full Text Available BACKGROUND: Recent research shows that vitamin D deficiency could be a risk factor in many chronic diseases like hypertension, diabetes mellitus, dyslipidemia, cardiovascular disease, some cancers, auto immune disease and tuberculosis. AIMS AND OBJECTIVES: To determine serum 25 - hydroxy vitamin D levels in patients with primary hypertension. This study also attempts to demonstrate an inverse co - relation between vitamin D levels and primary hypertension. MATERIALS AND METHOD S: 30 patients who are primary hype rtensive were selected, their vitamin D levels measured and the vitamin D levels were compared to age and sex matched non hypertensive controls. STATISTICAL METHODS: Descriptive and inferential statistical analysis has been carried out in the present study . ANOVA test and Chi - square test was applied for quantitative and qualitative data respectively to find significant associations between two variables. RESULTS: It is seen from this study that serum vitamin D levels was lower in hypertensive patients when compared to non - hypertensive controls. Hypertensive patients had lower levels of vitamin D with vitamin D status of deficiency in 50% of the cases and insufficiency in 43.3% of the cases and normal levels in 6.7% of the cases. Non hypertensive controls sho wed vitamin D status of normal in 66.7% of controls and insufficiency in 33.3% of the controls without deficiency. Age of the cases, duration of hypertension, systolic blood pressure and diastolic blood pressure inversely correlated to vitamin D levels. Bo dy mass index, diet of the patient, alcohol consumption, number of anti - hypertensive drugs, drug compliance, family history of hypertension and fundus status did not correlate to vitamin D levels. CONCLUSIONS: Based on the observations of the study, Vitami n D is an independent risk factor that is associated with primary or essential hypertension. The level of vitamin D also correlated inversely to age, duration of

    Masked hypertension has been 'unmasked' by the use of the out-of-office measurement of blood pressure, as home BP monitoring or ambulatory blood pressure monitoring has become available. The term masked hypertension could be used more widely than the original version of masked hypertension; morning hypertension, stress-induced hypertension, and nocturnal hypertension are all classified as subtypes of masked hypertension. Masked hypertension can also be seen in patients with diabetes, that could change clinical practice in diabetes. Masked hypertension is associated with cardiovascular events, but most of the outcome studies are on antihypertensive medications. Therefore, masked hypertension includes insufficient treatment of hypertension. In Dr Pickering's latest review of masked hypertension, prehypertension or high normal blood pressure was stressed as an associating factor with masked hypertension. The biggest theme in the field of hypertension is how we can detect masked hypertension. I present two interesting cases of possible masked hypertension in this commentary.

    Full Text Available Research Question: What are the factors responsible for pregnancy induced hypertension. Objectives: To determine whether maternal, demographic, clinical and socio-economic characteristics are predictive of hypertension associated with pregnancy. Study design: Cross â€" Sectional. Participants: 728 hypertensive pregnant mothers attending the ante-natal clinic and admitted to the inpatient department of obstetric unit. Study Variables: Maternal, demographic and socio-economic characteristics. Outcome variable: Hypertension associated with pregnancy. Statistical analysis: Percentages and proportions. Results: The relative incidence of pregnancy induced hypertension was 71.29%. The critical evaluation of social and demographic characteristics of 519 cases of pregnancy induced hypertension revealed that nulliparous, young women (15-25 years belonging to low socio-economic group with lower literacy status and higher house hold work load are more vulnerable to develop pregnancy induced hypertension. Inadequate diet having low protein, rich carbohydrate and extra salt intake played a crucial role in the development of pregnancy induced hypertension. Conclusions: i since the nulliparous and younger women are vulnerable to develop pregnancy induced hypertension, the age at first pregnancy be reasonably delayed. ii Balanced diet is to be ensured through appropriate nutrition education and within t he resources of the family. iii The heavy household work is to be avoided and adequate rest and sleep be ensured in those who are at risk of developing pregnancy induced hypertension.

    Among the conditions resulting from target organ damage by arterial hypertension, hypertensive cardiopathy is the one that exhibits the highest morbidity and mortality rates. Its prevention should be a target of all high blood pressure medical care programs. To identify risk factors for the development of hypertensive cardiopathy. A prospective cohort study was carried out in hypertensive patients assisted at the specialized arterial hypertension physicians’ offices of the “Carlos Manuel de Céspedes” Specialty Policlinic attached to the General University Hospital, Bayamo Municipality, Granma Province, Cuba, from January 1st, 2000 to December 31st, 2009. Multivariate analysis done to estimate the hazard rate (HR) of developing hypertensive cardiopathy, showed significant independent statistic association for most factors. The first place was occupied by lack of blood pressure control (HR=2.022; 95% CI: 1.659-2.465; p<0.005), followed by hypertension stage 2 (HR=2.015; 95% CI: 1.715-2.366; p<0.005). Another factors with significant HRs were microalbuminuria (HR=1.9; 95% CI: 1.6-2.2) and age over 60 years (HR=1.6; 95% CI: 1.4-1.9). Several risk factors must be considered for the prevention of hypertensive heart disease in high blood pressure patients.

    Full Text Available Hypertension is the first and the most common risk factor to diseases such as cardiovascular, stroke, and renal diseases. The aim of this study was to determine the factors relevant to hypertension knowledge, treatment, and control in southern Iran. In this cross-sectional study, conducted in Kohgiluye Boyer-Ahmad province, south of Iran, a total of 1836 hypertension patients were randomly selected to participate voluntarily in the study. Hypertension treatment and its control were defined during study. In addition, knowledge about hypertension was measured by hypertension knowledge level scale (HK-LS. Treatment rates were 75.5 and 37.7 percent for female and male, respectively. Habitat, education, income, family history with hypertension, smoking, and time of diagnosis to the disease were found to be related to the treatment of the disease. Control rates were 30.7 and 31.4 for males and females, respectively. Habitat, education, and time of diagnosis to the disease were related to control. Over 50 percent of patients had average knowledge on hypertension. Considering the low rate of control and knowledge on hypertension among patients, health care providers should reinforce their services to improve appropriate knowledge level among elders and, also, plan comprehensive programs to promote health in order to encourage patients change and reform their life style.

  12. Sex, the brain and hypertension: brain oestrogen receptors and high blood pressure risk factors.

    Hypertension is a major contributor to worldwide morbidity and mortality rates related to cardiovascular disease. There are important sex differences in the onset and rate of hypertension in humans. Compared with age-matched men, premenopausal women are less likely to develop hypertension. However, after age 60, the incidence of hypertension increases in women and even surpasses that seen in older men. It is thought that changes in levels of circulating ovarian hormones as women age may be involved in the increase in hypertension in older women. One of the key mechanisms involved in the development of hypertension in both men and women is an increase in sympathetic nerve activity (SNA). Brain regions important for the regulation of SNA, such as the subfornical organ, the paraventricular nucleus and the rostral ventral lateral medulla, also express specific subtypes of oestrogen receptors. Each of these brain regions has also been implicated in mechanisms underlying risk factors for hypertension such as obesity, stress and inflammation. The present review brings together evidence that links actions of oestrogen at these receptors to modulate some of the common brain mechanisms involved in the ability of hypertensive risk factors to increase SNA and blood pressure. Understanding the mechanisms by which oestrogen acts at key sites in the brain for the regulation of SNA is important for the development of novel, sex-specific therapies for treating hypertension. © 2016 Authors; published by Portland Press Limited.

    To evaluate the possible association that age, sex, excess weight, family history of hypertension, alcoholism, and sedentary lifestyle have with hypertension in the adult population of the city of Colima, Mexico. This was a population-based analytic cross-sectional study. A structured survey was used with 280 adults older than 30 years of age who were living in the city of Colima in 2001 and 2002. The variables studied were sex, age, weight, height, family history of hypertension, engaging in physical exercise, smoking, and consuming alcohol. Blood pressure (BP) was measured with the auscultatory method. Borderline or doubtful measurements were checked again four or five days later. Hypertension was defined as systolic BP > or = 140 mm Hg and diastolic blood pressure > or = 90 mm Hg, or as the person being under antihypertensive treatment. The odds ratios (ORs) of the variables studied were calculated, along with their 95% confidence intervals (95% CIs). The association between the variables and hypertension was estimated through logistic regression, and their interaction through the coefficient of the interaction products. The overall prevalence of hypertension was 28.6%. The prevalence was higher in men than in women (42.1% vs. 19.2%; OR = 3.04, 95% CI: 1.8 to 5.2) and in people older than 49 years than in people 30 to 49 years old (36.8% vs. 21.9%; OR = 2.07, 95% CI: 1.22 to 3.50). A family history of hypertension and excess weight were associated with hypertension, while physical exercise had a protective effect (OR = 0.45; 95% CI: 0.23 to 0.86). There was interaction between hypertension and age > or = 50 years, a family history of hypertension, overweight, and physical exercise, especially among women. The prevalence of hypertension in Colima is very similar to that for Mexico as a whole. The strong association that hypertension had with male gender, regardless of the other variables, emphasizes the need for promoting prevention campaigns that focus more on

    Life stress has been related to hypertension in various studies, but well-designed research carried out in disaster settings is scarce. Moreover, most research focuses on the primary victims and disregards effects on their caregivers. In a prospective, population-based cohort study, the authors tested the hypothesis that parents of adolescents who had been involved in the Volendam, Netherlands, pub fire on January 1, 2001 (n = 418) were more at risk of developing hypertension than parents from the same community whose children had not been involved in the fire (n = 1,462). Only residents without prior evidence of hypertension were included. The follow-up period covered 4 years (2001-2004). Assessment of hypertension was based on the records of family practitioners and pharmacies. The odds of developing new hypertension were 1.48 times higher in parents of fire victims than in control parents during the follow-up period (odds ratio = 1.48, 95% confidence interval: 1.09, 2.02). All analyses controlled for age, gender, socioeconomic status, family practice, history of chronic disease, and number of contacts with the family practitioner during follow-up. Since hypertension is an important risk factor for cardiovascular morbidity, it is important to provide interventions that help people fight the negative effects of disaster-related stress.

    Full Text Available Background: Hypertension is estimated to cause4.5% of the global disease burden. The prevalence of hypertension in Malaysia is 32.2%.Objective: To determine the prevalence of hypertension and its associated risk factors in two rural communities in Penang, Malaysia.Methods: This cross sectional study was conducted among all consenting residents aged 18 years and above from two villages in Penang. Besides the baseline demographic information, blood pressure was measured using a manual sphygmomanometer according to the American Heart Association Guidelines.Results: 50 out of 168 people were hypertensive, giving a prevalence rate of 29.8%. 50.0% of those found with hypertension were undiagnosed and 48.0% of those who were diagnosed with hypertension had uncontrolled blood pressure. Logistic regression analysis showed that age, history of alcohol consumption and BMI were found to be independently associated with hypertension.Conclusions: Age, education level, alcohol consumption and BMI are important risk factors associated with the prevalence of hypertension among the villagers. These risk factors are comparable to those reported in National Health and Morbidity Survery 2006 in Malaysia.

    1987-01-01

    The effects of cigarette smoking and hypertension on hemorheological variables (blood viscosity over a wide range of shear rates, plasma viscosity, microhematocrit, and plasma protein concentration) and on arterial stiffness (pulse wave velocity) were investigated in 33 normotensive men and 81 mild to moderately hypertensive men. Of these, 22 normotensive and 24 hypertensive subjects were cigarette smokers. Cigarette smoking and hypertension were independently associated with higher blood viscosity at all studied shear rates (from 0.2 to 241 sec-1) as well as with higher plasma viscosity, hematocrit, and pulse wave velocity. At constant hematocrit levels, hypertension remained associated with a higher blood viscosity, while the association with cigarette smoking disappeared. Normotensive smokers had the same increase of blood and plasma viscosity and pulse wave velocity as hypertensive nonsmokers. No interactive effects of hypertension or cigarette smoking on blood or arterial variables were observed, suggesting that the effect of these two factors on blood and vascular rheology are cumulative. Smoking and hypertension may change the flow properties of the blood and the behavior of the arterial wall and this may explain the arterial damage observed in cigarette smokers and hypertensive patients.

    Hypertension is an important public health issue in China, but there are few studies examining hypertension in ethnic groups in Yunnan, China. This study, Yunnan Minority Eye Study (YMES), was initially designed to determine the prevalence and impact of eye diseases, including hypertension and diabetes mellitus. As a part of YMES, the prevalence, awareness, treatment, and control of hypertension and the associated risk factors among the Yi ethnic population in rural China are reported. A population-based survey was conducted in 2012 with adult participants over 50 from rural communities in Shilin Yi Autonomous County, Yunnan Province, located in southwest China. A random cluster sampling method was used to select a representative sample. The participants' blood pressure, height, weight, and waist circumference were measured. Hypertension was defined as mean systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg, and/or current use of antihypertensive medications. A total of 2208 adults were assessed. The prevalence of hypertension was 38.5%, and the age- and gender-adjusted prevalence was 37.0%. The proportion of patients who were aware of their hypertension among those diagnosed with hypertension was 24.8%. Of those aware of having hypertension, 23.6% took antihypertensive drugs. Among all hypertensive patients, only 7.2% had controlled their hypertension (ethnic group in China. The ratio of awareness, treatment, and control of hypertension were considerately low. Hypertension education and screening programs in rural China are recommended to improve the health status of this population.

    Hypertension is the most prevalent chronic medical condition and a major risk factor for cardiovascular morbidity and mortality. In the majority of hypertensive cases, the underlying cause of hypertension cannot be easily identified because of the heterogeneous, polygenic and multi-factorial nature of hypertension. Metabolomics is a relatively new field of research that has been used to evaluate metabolic perturbations associated with disease, identify disease biomarkers and to both assess and predict drug safety and efficacy. Metabolomics has been increasingly used to characterize risk factors for cardiovascular disease, including hypertension, and it appears to have significant potential for uncovering mechanisms of this complex disease. This review details the analytical techniques, pre-analytical steps and study designs used in metabolomics studies, as well as the emerging role for metabolomics in gaining mechanistic insights into the development of hypertension. Suggestions as to the future direction for metabolomics research in the field of hypertension are also proposed.

    Full Text Available BACKGROUND: Type 2 diabetes is frequently associated with co-morbidities, including hypertension. Here we investigated if hypertension is a critical factor in myocardial remodeling and the development of cardiac dysfunction in type 2 diabetic db/db mice. METHODS: Thereto, 14-wks-old male db/db mice and non-diabetic db/+ mice received vehicle or angiotensin II (AngII for 4 wks to induce mild hypertension (n = 9-10 per group. Left ventricular (LV function was assessed by serial echocardiography and during a dobutamine stress test. LV tissue was subjected to molecular and (immunohistochemical analysis to assess effects on hypertrophy, fibrosis and inflammation. RESULTS: Vehicle-treated diabetic mice neither displayed marked myocardial structural remodeling nor cardiac dysfunction. AngII-treatment did not affect body weight and fasting glucose levels, and induced a comparable increase in blood pressure in diabetic and control mice. Nonetheless, AngII-induced LV hypertrophy was significantly more pronounced in diabetic than in control mice as assessed by LV mass (increase +51% and +34%, respectively, p<0.01 and cardiomyocyte size (+53% and +31%, p<0.001. This was associated with enhanced LV mRNA expression of markers of hypertrophy and fibrosis and reduced activation of AMP-activated protein kinase (AMPK, while accumulation of Advanced Glycation End products (AGEs and the expression levels of markers of inflammation were not altered. Moreover, AngII-treatment reduced LV fractional shortening and contractility in diabetic mice, but not in control mice. CONCLUSIONS: Collectively, the present findings indicate that type 2 diabetes in its early stage is not yet associated with adverse cardiac structural changes, but already renders the heart more susceptible to hypertension-induced hypertrophic remodeling.

    Full Text Available The knowledge on the etiology of breast cancer has advanced substantially in recent years, and several etiological factors are now firmly established. However, very few new discoveries have been made in relation to occupational risk factors. The International Agency for Research on Cancer has evaluated over 900 different exposures or agents to-date to determine whether they are carcinogenic to humans. These evaluations are published as a series of Monographs (www.iarc.fr. For breast cancer the following substances have been classified as “carcinogenic to humans” (Group 1: alcoholic beverages, exposure to diethylstilbestrol, estrogen-progestogen contraceptives, estrogen-progestogen hormone replacement therapy and exposure to X-radiation and gamma-radiation (in special populations such as atomic bomb survivors, medical patients, and in-utero exposure. Ethylene oxide is also classified as a Group 1 carcinogen, although the evidence for carcinogenicity in epidemiologic studies, and specifically for the human breast, is limited. The classification “probably carcinogenic to humans” (Group 2A includes estrogen hormone replacement therapy, tobacco smoking, and shift work involving circadian disruption, including work as a flight attendant. If the association between shift work and breast cancer, the most common female cancer, is confirmed, shift work could become the leading cause of occupational cancer in women.

    Hypertension remains a major societal problem affecting 76 million, or approximately one third, of US adults. While more prevalent in the older population, an increasing incidence in the younger population, including athletes, is being observed. Active individuals, like the young and athletes, are viewed as free of diseases such as hypertension. However, the increased prevalence of traditional risk factors in the young, including obesity, diabetes mellitus, and renal disease, increase the risk of developing hypertension in younger adults. Psychosocial factors may also be contributing factors to the increasing incidence of hypertension in the younger population. Increased left ventricular wall thickness and mass are increasingly found in young adults on routine echocardiograms and predict future cardiovascular events. This increasing incidence of hypertension in the young calls for early surveillance and prompt treatment to prevent future cardiac events. In this review we present the current epidemiological data, potential mechanisms, clinical implications, and treatment of hypertension in young patients and athletes.

    To evaluate the prevalence of hypertension (HT) in prevalent hemodialysis (HD) patients in our region, and to analyze the associated clinical and biochemical variables. Observational, cross-sectional and multicentric study including a representative sample of prevalent and stable (> 6 months) HD patients from all the HD centers (in and out of Hospitals) in Catalonia, Spain. Clinical and biochemical variables were recorded and predialysis blood pressure (BP) was determined (x3) in each dialysis session during 1 month, as well as the pre/post weight weekly. HT was defined as having at least one of these criteria: a mean (12 determinations) systolic BP > or = 140 mmHg or diastolic BP > or = 90 mmHg or antihypertensive treatment for at least 3 months. The sample comprised 387 patients from 32 of the 40 centers included, 231 of whom where men, with mean age of 63 +/- 14 years. The prevalence of HT in this sample was 67.4%, varying according to the etiology of End-Stage Renal Disease: diabetic 81%, vascular 81%, glomerulonephritis 61%, PKD 52%, unknown and others 64%. The prevalence of additional CV risk factors was 83%. One of each hypertensive 4 patients were treated, of whom 58% had systolic BP > or = 140 or dyastolic > or = 90, in contrast to 28% of untreated patients. The proportion of individuals according to the number of antihypertensive agents was 21% (no agents), 48% (1 agent), 20% (2 agents), 11% (3 agents). Blood pressure was higher among patients receiving higher number of antihypertensive agents. No differences according HT were found in age (64 +/- 13 in hypertensive patients versus 60 +/- 15 in normotensives), time on dialysis (4 +/- 4 vs 4 +/- 4 years), interdialysis weight gain (2.1 +/- 0.8 vs 2.1 +/- 0.8 kg), proportion of weight gain (3.3 +/- 1.4 vs 3.1 +/- 1.4%) or proportion of patients with > 5% weight gain with respect to dry weight (32.5 vs 27.3%). While 84% of hypertensive patients had an additional CV risk factor, this value was 67% in the

    To characterize older adults in Bogotá with high blood pressure and identify factors associated to this condition within this population. Using data from the Salud, Bienestar y Envejecimiento (SABE) (Health, Well-being and Aging) Bogotá Study, we analyzed community-dwelling adults 60 years and older with hypertension. We estimated the prevalence and used logistic regression models to identify factors associated to hypertension. The overall prevalence for hypertension was 56.9%. Older age (odds ratio [OR] = 1.46, 95% confidence interval [CI] = [1.07, 1.97]), having health insurance (OR = 4.15, CI = [1.95, 8.85]), cardiovascular diseases (ORs between 1.70 and 3.65), and poor self-rated health (OR = 1.57, CI = [1.20,2.06]) significantly increased the odds of hypertension. Most individuals received pharmacologic treatment (93.5%); however, 28.4% of individuals had uncontrolled hypertension. We found a high prevalence of hypertension in our cohort and found that comorbidities and poor self-rated health increase the odds of hypertension. Future studies need to tailor interventions for hypertension management in old age. © The Author(s) 2015.

    Full Text Available Hypertensive disorders of pregnancy (HDP are a group of medical complications in pregnancy and also a risk factor for severe pregnancy outcomes, but it lacks a large-scale epidemiological investigation in recent years. This survey represents a multicenter cross-sectional retrospective study to estimate the prevalence and analyze the risk factors for HDP among the pregnant women who had referred for delivery between January 1st 2011 and December 31st 2011 in China Mainland. A total of 112,386 pregnant women were investigated from 38 secondary and tertiary specialized or general hospitals randomly selected across the country, of which 5,869 had HDP, accounting for 5.22% of all pregnancies. There were significant differences in the prevalence of HDP between geographical regions, in which the North China showed the highest (7.44% and Central China showed the lowest (1.23%. Of six subtypes of HDP, severe preeclampsia accounted for 39.96%, gestational hypertension for 31.40%, mild preeclampsia for 15.13%, chronic hypertension in pregnancy for 6.00%, preeclampsia superimposed on chronic hypertension for 3.68% and eclampsia for 0.89%. A number of risk factors for HDP were identified, including twin pregnancy, age of >35 years, overweight and obesity, primipara, history of hypertension as well as family history of hypertension and diabetes. The prevalence of pre-term birth, placental abruption and postpartum hemorrhage were significantly higher in women with HDP than those without HDP. The possible risk factors confirmed in this study may be useful for the development of early diagnosis and appropriate treatment of HDP.

    This study sought to evaluate the association between socioeconomic variables and the quality of life of elderly hypertensive patients treated under the Family Health Program in the city of Montes Claros, Minas Gerais, Brazil. An analytical cross study was conducted in a representative sample of 294 elderly hypertensive patients. Data were collected using a questionnaire on socioeconomic characteristics and quality of life (MINICHAL). The data were analyzed using the nonparametric Mann-Whitney and Kuskall-Wallis tests. The results showed that marital status, religion and education affect the quality of life of elderly hypertensive patients in a statistically significant way. Elderly hypertensive patients who were single/divorced/widowed, evangelical, spiritualist and belonging to other religious bodies, illiterate achieved lower scores in terms of quality of life. For the remaining variables, there was no statistical association. The conclusion, drawn is that socioeconomic factors such as marital status, education and religion influence the quality of life of elderly hypertensive patients.

    2013-12-01

    Full Text Available Background: Hypertension is a chronic condition of concern due to its role in the causation of coronary heart disease, stroke and other  complications. It is one of the major risk factors for cardio-vascular mortality accounting for 20-50% of all deaths. Children with higher blood pressure tend to maintain those levels during adulthood also. Objectives:  Assess the prevalence of hypertension in adolescents (11-18 years, its risk factors and their socio-demographic co-relates. Material and Method:  Prevalence of adolescent hypertension in previous studies was 7% and the sample size accordingly came to be 1314 with a relative precision of 20%. Multistage sampling technique was used. Half each of the sample size was covered in urban and rural areas . Households in the selected colonies in the urban areas and villages were randomly selected and the adolescents interviewed and examined. Their responses were recorded on a pretested questionnaire and results drawn. Data were analysed using Epi-info and SPSS and chi-square test applied. Results:   Prevalence of adolescent hypertension was found to be 5.3% (72 out of 1340; significantly associated with type of family (P<0.001, educational status (P<0.001, occupation (P<0.001, BMI (P<0.01, and smoking habit (P<0.05. However, no relationship of hypertension was found with salt intake, type of diet, exercise, alcohol consumption, stress and family history of hypertension. Conclusion: Socio-demographic factors certainly influence the prevalence and probability of occurrence of adolescent hypertension but the effect of established risk factors (for adult hypertension needs to be further evaluated for adolescent hypertension and more studies are required in this area.

    To assess the prevalence of hypertension, elevated blood pressure and cardiovascular risk factors among HIV-positive individuals in rural Rakai District, Uganda. We assessed 426 HIV-positive individuals in Rakai, Uganda from 2007 to 2010. Prevalence of hypertension and elevated blood pressure assessed by clinical measurement was compared to clinician-recorded hypertension in case report forms. Multiple logistic regression and z-tests were used to examine the association of hypertension and elevated blood pressure with age, sex, body mass index (BMI), CD4 cell count and antiretroviral treatment (ART) use. For individuals on antihypertensives, medication utilisation was reviewed. The prevalence of hypertension (two elevated blood pressure readings at different time points) was 8.0% (95% CI: 5.4-10.6%), and that of elevated blood pressure (one elevated blood pressure reading) was 26.3% (95% CI: 22.1-30.5%). Age ≥50 years and higher BMI were positively associated with elevated blood pressure. ART use, time on ART and CD4 cell count were not associated with hypertension. Eighty-three percent of subjects diagnosed with hypertension were on antihypertensive medications, most commonly beta-blockers and calcium channel blockers.

    To investigate the prevalence, awareness, treatment, and control of hypertension, and the associated risk factors among adults in Xi'an, China.From October to December 2013, participants in Xi'an, China were recruited for the study by using a multiple-stage sampling method. A self-developed questionnaire with an additional health examination was used to collect data on the history of hypertension diagnosis and antihypertensive medication. The status on prevalence, awareness, treatment, and control of hypertension were analyzed and related risk factors were identified by using logistic regression analysis.A total of 8193 participants were included with an overall prevalence of hypertension of 20.4%. Among the hypertensive participants, 63.7% were aware of their conditions, 47.3% took antihypertensive medication, and 17.8% had their blood pressure (BP) controlled within 140/90 mm Hg. More complications and less frequent BP measurements were associated with hypertension. Older participants, non-drinkers, and those with more complications and more frequent BP measurements were more aware of their hypertension. Being older, living in an urban area, and having more frequent BP measurements were all factors for better treatment. Participants who were women, living in an urban area, with a higher educational level and who were not obese were more likely to have their hypertension controlled.The prevalence of hypertension among adults in Xi'an is high with suboptimal low awareness, treatment, and control rates. Further comprehensive integrated strategies based on these risk factors should be taken into account in order to improve the prevention, awareness, treatment, and control of hypertension.

    Full Text Available Hypertension is one of the most prevalent and powerful contributor to cardiovascular diseases, the leading cause of death worldwide. The objective of the present study is to examine the relationship of the closely knit risk factors of cardiovascular diseases that can coexist along with hypertension which are likely to influence the blood pressure levels among adults with a history of hypertension. This study was conducted to examine the risk factors of hypertension among 1640 adults aged 40 to 65 years with a history of hypertension in six hospitals specializing in cardiovascular disease in Madurai city. They were categorized according to the stage of hypertension based on JNC-7 criteria (2004. Background and dietary data were recorded using a structured interview schedule. Anthropometric measurements, blood pressure and lipid profile were measured using standardized procedures. The findings of the present study revealed that vegetarianism could be more associated with normal or pre hypertension and non vegetarianism with stage I and stage II hypertension. Body weight and BMI of the adults also showed a correlating effect with the level of hypertension. Lifestyle pattern of the adults revealed that habits such as smoking, alcohol, tobacco and lack of exercise were more common among adults with higher levels of blood pressure. Adults with normal blood pressure had more favourable lipid levels when compared to the other groups. Best results in the prevention of chronic diseases can only be achieved by fully recognizing the essential role of diet, nutrition and physical activity along with managing various other principal risk factors for chronic disease, namely, tobacco use and alcohol consumption.

    There is an increasing appreciation for a series of less traditional risk factors that should not be ignored when considering type 2 diabetes, obesity, hypertension, and cardiovascular disease. These include aortic stiffness, cardiac structure, impaired endothelial function and obstructive sleep apnea. They are associated to varying degrees with each disease categorization and with each other. It is not clear whether they represent additional complications, concomitants or antecedents of disease. Starr County, Texas, with its predominantly Mexican American population has been shown previously to bear a disproportionate burden of the major disease categories, but little is known about the distribution of these less traditional factors. Type 2 diabetes, obesity and hypertension frequencies were determined through a systematic survey of Starr County conducted from 2002 to 2006. Individuals from this examination and an enriched set with type 2 diabetes were re-examined from 2010 to 2014 including assessment of cardiac structure, sleep apnea, endothelial function and aortic stiffness. Individual and combined frequencies of these inter-related (i.e., axis) conditions were estimated and associations evaluated. Household screening of 5230 individuals aged 20 years and above followed by direct physical assessment of 1610 identified 23.7 % of men and 26.7 % of women with type 2 diabetes, 46.2 and 49.5 % of men and women, respectively with obesity and 32.1 and 32.4 % with hypertension. Evaluation of pulse wave velocity, left ventricular mass, endothelial function and sleep apnea identified 22.3, 12.7, 48.6 and 45.2 % of men as having "at risk" values for each condition, respectively. Corresponding numbers in women were 16.0, 17.9, 23.6 and 28.8 %. Cumulatively, 88 % of the population has one or more of these while 50 % have three or more. The full axis of conditions is high among Mexican Americans in Starr County, Texas. Individual and joint patterns suggest a genesis well

    Background Pulmonary hypertension (PH) is common in patients with maintenance hemodialysis (MHD) and is associated with high mortality. This study analyzed clinically relevant factors for pulmonary hypertension in MHD patients and the effect of serum pentraxin3 (PTX3) in the pathogenesis of PH to provide the basis for early diagnosis and treatment of MHD patients with PH. Material/Methods This study included 60 MHD patients (group A) and 30 healthy controls (group B). Group A was further divided into PH and non-PH groups. Clinical characteristics, auxiliary examination results and serum PTX3 level of the PH and non-PH groups were compared. Binary logistic regression was used to assess the risk factors for PH in MHD patients. ROC curve was applied to evaluate the diagnostic value of PTX3 in PH. Results The incidence rate of PH in MHD patients was 50%, and most presented as mild to moderate. Compared with the non-PH group, patients in PH group presented significantly longer atrial diameter, right ventricular diameter and main pulmonary artery diameter (PMHD patients. AUC of PTX3 was 0.721 (95%CI: 0.590–0.851, P=0.003). Conclusions The prevalence of PH was higher in MHD patients and mostly presented as mild to moderate. Such patients often developed heart structural changes and cardiac ultrasound was highly recommended. Serum PTX3 level was significantly elevated and could be used as a marker of PH in MHD patients.

    Asthma and obesity-related health problems disproportionately impact low-income ethnic minority communities residing in urban areas. Environmental risk factors, particularly those related to housing and indoor air, may impact the development or exacerbation of asthma. There is increasing evidence to suggest a link between obesity-related health problems and asthma. Previous studies have also reported that immigrant status may influence myriad risk factors and health outcomes among immigrant populations. The Arab American Environmental Health Project (AAEHP) was the first study to explore environmental health problems among Arab Americans. This paper examined whether hypertensive status modified the relationship between environmental risk factors and asthma among Arab Americans in metro Detroit. An environmental risk index (ERI) was used to quantify household environmental risk factors associated with asthma. Physician diagnosed hypertension was self-reported, and asthma status was determined using responses to a validated symptoms checklist and self-reported diagnosis by a physician. Hypertension significantly modified the relationship between ERI and asthma in this study population. The positive association between household environmental risk factors and asthma was stronger among participants diagnosed with hypertension. Effect modification of the relationship between environmental risk factors and asthma could have serious implications among high-risk communities. However, further research is needed to elucidate the relationships between hypertension, environmental risk factors, and asthma.

    Imbalances in circulating angiogenic factors contribute to the pathogenesis of preeclampsia. To characterize levels of angiogenic factors in pregnant women with chronic hypertension, we prospectively followed 109 women and measured soluble fms-like tyrosine kinase 1 (sFlt1), soluble endoglin, and placental growth factor at 12, 20, 28, and 36 weeks' gestation and postpartum. Superimposed preeclampsia developed in 37 (34%) and was early onset (hypertension. We conclude that alterations in angiogenic factors are detectable before and at the time of clinical diagnosis of early onset superimposed preeclampsia, whereas alterations were observed only at the time of diagnosis in women with late-onset superimposed preeclampsia. Longitudinal measurements of angiogenic factors may help anticipate early onset superimposed preeclampsia and facilitate diagnosis of superimposed preeclampsia in women with chronic hypertension.

    Full Text Available Background. Blood pressure (BP control is poor among hypertensives in many parts of sub-Saharan Africa. A potentially modifiable factor for control of BP is medication nonadherence (MNA; our study therefore aimed to determine factors associated with MNA among hypertensives in Ghana and Nigeria. Methodology. We conducted a multicenter cross-sectional study. Patients were recruited from Korle-Bu Hospital (n=120, Ghana; and University of Port Harcourt Teaching Hospital, (n=73 Apapa General Hospital Lagos (n=79 and University College Hospital Ibadan (n=85, Nigeria. Results. 357 hypertensive patients (42.6% males participated. MNA was found in 66.7%. Adherence showed correlation with depression (r=-0.208, P<0.001, concern about medications (r=-0.0347, P=0.002, and knowledge of hypertension (r=0.14, P=0.006. MNA was associated with formal education (P=0.001 and use of herbal preparation (P=0.014. MNA was found in 61.7% of uninsured participants versus 73.1% of insured participants (P=0.032. Poor BP control was observed in 69.7% and there was significant association between MNA and poor BP control (P=0.006. Conclusion. MNA is high among hypertensives in Ghana and Nigeria and is associated with depression, concern about hypertensive medications, formal education, and use of herbal preparations. The negative association between health insurance and MNA suggests interplay of other factors and needs further investigation.

    Full Text Available Introduction: Hypertension is a global health challenge and its prevalence is increasing rapidly amongst adults in many African countries. Some studies on the prevalence and risk factors of hypertension have been conducted in Nigeria, but none within Delta State. We assessed the prevalence of hypertension and associated risk factors amongst adults in three villages in the Ibusa community in Delta State, Nigeria.Method: Homesteads were randomly selected and all consenting adults (≥ 18 years of age were recruited for this cross-sectional study (134 individuals: 48 men, 86 women. Sociodemographic data and anthropometric measurements (weight, height and abdominal circumference were recorded. Diagnosis of hypertension was based on blood pressure≥ 140/90 mmHg.Result: Hypertension prevalence in this rural community was 44%. Results from one village (Ogboli: 82% and ethnic group (Ibo: 50% were significantly higher than in others in the same variable category. Multivariate logistic regression analysis suggested increasing age, increasing body mass index and high salt intake as prominent risk factors for hypertension. Lack of funds and equipment shortage in clinics were most often reported as barriers to healthcare.Conclusion: A nutritional education programme to promote low-cholesterol and low-salt diets is recommended to specifically target people in higher-risk areas and of higher-risk ethnicity. Local barriers to accessing health care need to be addressed.

    Cardiovascular risk factors in people on antiretroviral treatment (ART) are poorly documented in resource-constrained settings. A cross-sectional study was conducted in 2009 to assess prevalence of diabetes and hypertension in a sample of 242 HIV-infected patients who had initiated ART between 1998 and 2002 in Dakar, Senegal (ANRS 1215 observational cohort). World Health Organization (WHO) criteria were applied to diagnose diabetes and hypertension. Multiple logistic regressions were used to identify factors associated with diabetes and hypertension. Patients had a median age of 46 years and had received ART for a median duration of about 9 years. 14.5% had diabetes and 28.1% had hypertension. Long duration of ART (≥119 months), older age, higher body mass index (BMI), and higher levels of total cholesterol were associated with higher risks of diabetes. Older age, higher BMI at ART initiation, and higher levels of triglycerides were associated with higher risk of hypertension. This study shows that diabetes and hypertension were frequent in these Senegalese HIV patients on ART. It confirms the association between duration of ART and diabetes and highlights the need to implement programs for prevention of cardiovascular risk factors in HIV patients from resource-constrained settings.

    Multimorbidity has become the norm worldwide as populations age. It remains, however, infrequently researched. This study evaluated factors associated with multimorbidity in a predominantly Chinese hypertensive population. We included all adult patients prescribed their first antihypertensive agents in the entire public sector in Hong Kong from a validated database. Multimorbidity was defined as having one or more medical conditions (cardiovascular diseases; respiratory diseases; diabetes or impaired fasting glucose; renal disease) in addition to hypertension. We studied the prevalence of multimorbidity and performed multinomial regression analyses to evaluate factors independently associated with multimorbidity. 223,286 hypertensive patients (average age of 59.9 years, SD 17.6) were included. The prevalence of having 0, 1 and ≥ 2 additional conditions was 59.6%, 32.8% and 7.5%, respectively. The most common conditions were cardiovascular disease (24.2%) and diabetes (23.0%), followed by respiratory disorders (14.6%) and renal disease (10.9%). Older age (>50 years), male sex, lower household income, receipt of social security allowance and suboptimal blood pressure control (>140 mmHg or >90 mmHg; >130 mmHg or >80 mmHg for diabetes patients; AOR = 3.38-4.49) were significantly associated with multimorbidity. There exists a synergistic effect among these variables as older (≥ 70 years), male patients receiving security allowance had substantially higher prevalence of multimorbidity (19.9% vs 7.5% among all patients). Multimorbidity is very common in hypertensive patients and its prevalence increased markedly with the presence of risk factors identified in this study. Hypertensive patients with multimorbidities should receive more meticulous clinical care as their blood pressure control tends to be poorer.

    The definition of hypertension has continuously evolved over the last 50 years. Hypertension is currently defined as a blood pressure greater than 140/90mmHg. One in every four people in the US has been diagnosed with hypertension. The prevalence of hypertension increases further with age, affecting 75% of people over the age of 70. Hypertension is by far the most common risk factor identified in stroke patients. Hypertension causes pathologic changes in the walls of small (diameter<300 microns) arteries and arterioles usually at short branches of major arteries, which may result in either ischemic stroke or intracerebral hemorrhage. Reduction of blood pressure with diuretics, β-blockers, calcium channel blockers, and angiotensin-converting enzyme (ACE) inhibitors have all been shown to markedly reduce the incidence of stroke. Hypertensive emergency is defined as a blood pressure greater than 180/120mmHg with end organ dysfunction, such as chest pain, shortness of breath, encephalopathy, or focal neurologic deficits. Hypertensive encephalopathy is believed to be caused by acute failure of cerebrovascular autoregulation. Hypertensive emergency is treated with intravenous antihypertensive agents to reduce blood pressure by 25% within the first hour. Selective inhibition of cerebrovascular blood vessel permeability for the treatment of hypertensive emergency is beginning early clinical trials. © 2014 Elsevier B.V. All rights reserved.

    Immune system activation contributes to the pathogenesis of hypertension and the resulting progression of chronic kidney disease. In this regard, we recently identified a role for proinflammatory Th1 T-lymphocyte responses in hypertensive kidney injury. Because Th1 cells generate interferon-γ and tumor necrosis factor-α (TNF-α), we hypothesized that interferon-γ and TNF-α propagate renal damage during hypertension induced by activation of the renin-angiotensin system. Therefore, after confirming that mice genetically deficient of Th1 immunity were protected from kidney glomerular injury despite a preserved hypertensive response, we subjected mice lacking interferon-γ or TNF-α to our model of hypertensive chronic kidney disease. Interferon deficiency had no impact on blood pressure elevation or urinary albumin excretion during chronic angiotensin II infusion. By contrast, TNF-deficient (knockout) mice had blunted hypertensive responses and reduced end-organ damage in our model. As angiotensin II-infused TNF knockout mice had exaggerated endothelial nitric oxide synthase expression in the kidney and enhanced nitric oxide bioavailability, we examined the actions of TNF-α generated from renal parenchymal cells in hypertension by transplanting wild-type or TNF knockout kidneys into wild-type recipients before the induction of hypertension. Transplant recipients lacking TNF solely in the kidney had blunted hypertensive responses to angiotensin II and augmented renal endothelial nitric oxide synthase expression, confirming a role for kidney-derived TNF-α to promote angiotensin II-induced blood pressure elevation by limiting renal nitric oxide generation.

Stimulation of RAAS also contributes to hypertension-related target organ damage. The renin–angiotensinogen reaction is the first and rate-limiting step in the generation of angiotensin II (Ang II and has been a target of antihypertensive drug development for decades. Aliskiren is the first in a new class of orally effective direct renin inhibitors (DRIs and is approved for the treatment of hypertension in humans. It effectively reduces BP in the general population of hypertensive patients and has a tolerability and safety profile similar to placebo. Aliskiren has favorable effects on vascular inflammation and remodeling, on neurohumoral mediators of various forms of cardiovascular disease, including heart failure, and on proteinuria in diabetic patients. Additional outcome trials are needed to establish the role of this novel class of antihypertensive medication in preventing cardiovascular disease morbidity and mortality.Keywords: hypertension, renin inhibitors, renin-angiotensin-aldosterone system

    To study the effect of disease duration, treatment and risk factors on QTc interval among young hypertensives. A case-control study was conducted on 142 hypertensives (60 males, 82 females) taking calcium channel blocker (CCB) or angiotensin-converting enzyme inhibitor (ACEI) as monotherapy. After blood pressure measurement, we recorded lead II electrocardiograph with minimum ten waveforms. QTc was derived from average of ten values using Bazett's formula. QTc interval >0.43 s in male and >0.45 s in female was considered abnormal. Cases had mean duration of hypertension 5 years, mean age of 40 years, and poor blood pressure control (systolic blood pressure >140 and diastolic blood pressure >90 mm of Hg). Newly diagnosed hypertensives had significantly higher QTc values than the matched known cases (0.44 vs. 0.42 s, P < 0.05). Known hypertensives did not differ significantly in QTc values by the duration of disease. CCB users showed small, insignificant disadvantage for abnormally prolonged QTc values than ACEI users. With coexisting diabetes, smoking, and positive family history of hypertension, there was odds risk of 7.69, 2.75, and 2.54, respectively for prolonged QTc. Our study showed prolonged QTc in hypertensives more so in newly diagnosed, unaffected by duration or use of ACEI, or CCB but associated with modifiable risk factors. This underscores high risk of repolarization abnormality-induced future events, suggesting early screening of hypertension, strict blood pressure control, optimum use of QTc measurement, and preventive pharmacotherapy to reduce this aftermath.

Cross-sectional study conducted in 2013 with 347 teenagers attending schools in Natal, Rio Grande do Norte, Brazil, who answered a form about the socioeconomic profile, physical activity, eating habits and family history of disease and who underwent physical examination. For analytical analysis, two groups were formed: students with the Nursing Diagnosis overweight (n=100 and students without this diagnosis (n=247. Results. the risk factors for hypertension associated with the Nursing Diagnosis were: abdominal obesity (OR=40.0, food intake rich in sugar and fat (OR=40.0, family history of hypertension (OR=6.9, obesity and diabetes (OR=2.0, abnormal systolic and diastolic blood pressure (OR=5.5. Conclusion. the risk factors for hypertension that presented association with the Nursing Diagnosis overweight were abdominal obesity, eating habits, family history of diseases and abnormal blood pressure. These findings may contribute to prevent hypertension in adolescents, in that it directs the gaze of nurses to develop effective measures to address these risk factors.

  16. Epidemiology and Pathophysiology of Chronic Thromboembolic Pulmonary Hypertension: Risk Factors and Mechanisms.

    Medrek, Sarah; Safdar, Zeenat

    2016-01-01

    Chronic thromboembolic pulmonary hypertension (CTEPH) occurs when thromboemboli travel to the pulmonary vasculature, fail to resolve, and cause elevated pulmonary arterial pressure. Untreated, this disease leads to progressive right heart failure and death. It develops in approximately 1% to 5% of patients who suffer an acute pulmonary embolism (PE) and has an overall incidence of 3 to 30 per million in the general population. While it is not entirely evident why most but not all people are able to clear this clot burden, there are known risk factors for the development of CTEPH. These include signs of right heart strain at the time of incident PE, inherited coagulopathies, inflammatory conditions, hypothyroidism, and a history of splenectomy. Since CTEPH can be treated both surgically and medically, it is critical to understand the pathophysiology of the disease so affected patients can be identified and diagnosed appropriately.

    The study gives a survey of the factors most frequently mentioned in the literature as factors likely to adversely affect a pregnancy. One essential aspect is the discussion of those factors that can be counted among the causes of malformations, as among others, prenatal radiation exposure. The study prepared within the framework of the research project `Radiobiological environmental monitoring in Bavaria` is intended to serve as a basis for a retrospective and prospective evaluation of infant mortality, perinatal conditions and occurrence of malformations in Bavaria, with the principal idea of drawing up an environment - related health survey. The study therefore, in addition to ionizing radiation also takes into account other detectable risks within the ecologic context, as e.g. industrial installations, refuse incineration plants or waste dumps, or urbanity.

    2014-01-01

    Full Text Available Established standards for first-line hypertension management include lifestyle modification and behavior change. The degree to which and how lifestyle modification is systematically integrated into studies of first-line drug management for hypertension is of methodological and clinical relevance. This study systematically reviewed the methodology of articles from a recent Cochrane review that had been designed to inform first-line medical treatment of hypertension and was representative of high quality established clinical trials in the field. Source articles (n=34 were systematically reviewed for lifestyle interventions including smoking cessation, diet, weight loss, physical activity and exercise, stress reduction, and moderate alcohol consumption. 54% of articles did not mention lifestyle modification; 46% contained nonspecific descriptions of interventions. We contend that hypertension management research trials (including drug studies need to elucidate the benefits and risks of drug-lifestyle interaction, to support the priority of lifestyle modification, and that lifestyle modification, rather than drugs, is seen by patients and the public as a priority for health professionals. The inclusion of lifestyle modification strategies in research designs for hypertension drug trials could enhance current research, from trial efficacy to clinical outcome effectiveness, and align hypertension best practices of a range of health professionals with evidence-based knowledge translation.

  19. Bioactive factors in uteroplacental and systemic circulation link placental ischemia to generalized vascular dysfunction in hypertensive pregnancy and preeclampsia.

    2015-06-15

    Preeclampsia is a pregnancy-associated disorder characterized by hypertension, and could lead to maternal and fetal morbidity and mortality; however, the pathophysiological mechanisms involved are unclear. Predisposing demographic, genetic and environmental risk factors could cause localized abnormalities in uteroplacental cytoactive factors such as integrins, matrix metalloproteinases, cytokines and major histocompatibility complex molecules leading to decreased vascular remodeling, uteroplacental vasoconstriction, trophoblast cells apoptosis, and abnormal development of the placenta. Defective placentation and decreased trophoblast invasion of the myometrium cause reduction in uteroplacental perfusion pressure (RUPP) and placental ischemia/hypoxia, an important event in preeclampsia. RUPP could stimulate the release of circulating bioactive factors such as the anti-angiogenic factors soluble fms-like tyrosine kinase-1 and soluble endoglin that cause imbalance with the pro-angiogenic factors vascular endothelial growth factor and placental growth factor, or cause the release of inflammatory cytokines, reactive oxygen species, hypoxia-induced factor-1 and AT1 angiotensin receptor agonistic autoantibodies. The circulating bioactive factors target endothelial cells causing generalized endotheliosis, endothelial dysfunction, decreased vasodilators such as nitric oxide and prostacyclin and increased vasoconstrictors such as endothelin-1 and thromboxane A2, leading to increased vasoconstriction. The bioactive factors also stimulate the mechanisms of VSM contraction including Ca(2+), protein kinase C, and Rho-kinase and induce extracellular matrix remodeling leading to further vasoconstriction and hypertension. While therapeutic options are currently limited, understanding the underlying mechanisms could help design new interventions for management of preeclampsia.

    The health of older persons has not been a major priority in many African countries. Hypertension is one of the common health problems of older persons. However, there is little information on the prevalence of hypertension in older adults in Africa. This is in spite of the fact that Africa has the highest age-standardized prevalence of hypertension in the world. We therefore present this protocol to conduct a systematic review and meta-analysis on the prevalence of hypertension and the level of its awareness among older persons living in Africa. Major databases (EMBASE, MEDLINE, Academic Search Complete, CINAHL, PsycINFO) and unpublished literature will be searched to identify population-based studies on hypertension in adults aged 50 years and older living in Africa. Eligible articles are those which use the 140/90-mmHg cutoff to diagnose hypertension and were published from 1980 to present. We will exclude subjects in restricted environments such as patients and refugees. Articles will be independently evaluated by two reviewers to determine if they meet the inclusion criteria. They will also evaluate the quality of included studies using a validated tool by Hoy and colleagues for prevalence studies. The main outcome is the prevalence of hypertension while the explanatory variables include demographic, socio-economic, dietary, lifestyle and behavioural factors. Effect sizes in bivariate and multivariate analyses will be presented as odds or prevalence ratios. We will explore for heterogeneity of the standard errors across the studies, and if appropriate, we will perform a meta-analysis using a random-effects model to present a summary estimate of the prevalence of hypertension in this population. The estimates of the prevalence, the risk factors and the level of awareness of hypertension could help in galvanizing efforts at prioritizing the cardiovascular health of older persons in Africa.

    Bach, Leon A

    2012-01-01

    The insulin-like growth factor system plays an important role in renal physiology and it is perturbed in a range of kidney diseases. Some insulin-like growth factor (IGF) actions in the kidney are mediated by nitric oxide. Growth hormone and IGF-binding proteins may contribute to renal diseases via effects on podocytes and proximal tubule cells. In contrast, growth hormone and IGF-I may counteract the catabolic consequences of end-stage renal disease. Polymorphisms in the IGF system are associated with hypertension. Further studies are needed to determine whether modulating the IGF system may have a role in treating kidney diseases and/or hypertension.

    The objective of this study was to examine the risk of female sexual orgasmic disorder among a group of women with hypertension in Malaysia. The associated factors were also examined. This cross-sectional study involved 348 hypertensive women attending the primary care or hypertension clinic in a teaching hospital in Malaysia. Female sexual orgasmic disorder was assessed using the Orgasmic subscale of the Malay Version of the Female Sexual Function Index (MVFSFI). Basic socio-demographic data of the subjects was collected using a predesigned questionnaire. Medical records were reviewed to gather patients' medical information. The risk of female sexual orgasmic disorder among hypertensive women was 14.1%. Univariate analysis found that older age, longer duration of marriage, lower educational level, and menopause were associated with higher risk of female sexual orgasmic disorder. These factors were not significant in multivariate analysis. The risk of female sexual orgasmic disorder was relatively low in Malaysian women with hypertension. No risk factors were associated with female sexual orgasmic disorder in the current study. Copyright © 2013 Wiley Publishing Asia Pty Ltd.

    The authors aimed to compare renal function by estimated glomerular filtration rate and albuminuria in 3 groups of women: nulliparous women, women with a history of normotensive pregnancies, and women with a history of at least one hypertensive pregnancy. Women who participated in the second Family Blood Pressure Program Study visit (2000-2004) and had serum creatinine and urine albumin measurements (n=3015) were categorized as having had no pregnancy lasting >6 months (n=341), having had only normotensive pregnancies (n=2199), or having had at least 1 pregnancy with hypertension (n=475) based on a standardized questionnaire. Women who reported having had at least one pregnancy with hypertension were significantly more likely to be hypertensive (75.6% vs 59.4%, Ppregnancies. There was a significantly greater risk of microalbuminuria (urine albumin-creatinine ratio >25 mg/g) in those who reported at least one pregnancy with hypertension (odds ratio, 1.37; confidence interval, 1.02-1.85; P=.04) than in those with normotensive pregnancies, after adjusting for risk factors for chronic kidney and cardiovascular disease. Hypertension in pregnancy is associated with an increased risk of future microalbuminuria.

    Literature review and original data concerning the most common cause of inherited thrombophilia - activated protein C resistance have been presented. One hundred and three patients with confirmed venous thromboembolism have been investigated for activated protein C resistance with 2 ( nd ) generation "Diagnostica Stago" test. Activated protein C resistance has been found in 22.3 % cases. In the group of 70 healthy unselected men and women, matched by sex and age, this mutation has been found in 7.1% cases. Out of 101 patients with pulmonary thromboembolism confirmed by pulmoangiography or perfusion lung scan, 78 have been investigated by Doppler echocardioscopy in order to detect pulmonary hypertension after 1.5 months.

    Objective The aim of the study is to investigate the effects of psychosocial factors on the treatment of elderly patients with hypertension. Methods Atotalof 260 elderly Chinese patients with hypertension were treated with benazepril alone or benazepril combined with amlodipine for 8 weeks. The target blood pressure (BP) (both <140 mmHg systolic, SBP, and <90 mmHg diastolic, DBP)was achieved in 180 patients, who were then assigned to the well-controlled BP group; the rest were placed in the modestly controlled BP group. The psychosocial factors present in both groups were assessed by the Hamilton depression scale, Hamilton anxiety scale, life event scale and social support evaluation list before and after anti-hypertensive treatment. Results There were no significant differences in gender, mean age, hist ory of hypertension, education and smoking habit, or in SBP and DBP between the groups before treatment.Significant differences were also not found in all psychosocial factors before and after treatment in the patients. However, significant differences were found between the groups with respect to post-treatment SBP and marital status. The patients with modestly controlled BP had significantly higher scores, as well as incidents, on the depressive, anxiety, and stressful life event scales than those with well-controlled BP. The patients with well-controlled BP had significantly higher scores in tangible support, subjective support,and social support compared to the patients with modestly controlled BP. Logistic regression analysis showed the independent contribution of psychosocial factors in reaching the goal of lowering BP at treatment endpoint in these hypertensive patients. Conclusions The results suggest that psychosocial factors stand as a main barrier to achieving the BP-lowering target in the management of elderly Chinese patients with hypertension.

    Objective In clinical practice, patient characteristics predicting resistant hypertension (RH) include higher blood pressure levels, left ventricular hypertrophy, older age, obesity, chronic kidney disease and diabetes. On the contrary little is known about the role of serum uric acid (SUA) as a risk factor for RH in subjects from general population. Material and methods 580 elderly subjects aged ≥65 years were enrolled in the Risk Of Vascular complications Impact of Genetics in Old people (ROVIGO) study. RH was defined as the failure to maintain blood pressure values below 140 mmHg (systolic) and 90 mmHg (diastolic) despite therapeutic interventions that include appropriate lifestyle measures plus adherence to treatment with full doses of at least three antihypertensive drugs, including a diuretic. RH was confirmed using 24-h ambulatory blood pressure measurement. Hyperuricemic was defined as the subjects having SUA ≥6.8 mg/dl or taking uricosuric drugs. Gender-specific odds ratio (OR) for RH was calculated by logistic regression analysis. Results The prevalence of RH was 5.7% in the cohort and was higher in women (8.3%) than in men (3.0%, p hypertension in women (odds ratio 3.11, 95% confidence intervals 1.06–9.1, p = 0.03) but not in men. Conclusions In elderly women from the general population, an SUA value of ≥6.8 mg/dl triples the risk of RH. SUA assessment should be recommended to better define the pattern of risk associated with RH. PMID:28027534

    Background T8590C polymorphism of CYP4A11 has been associated with hypertension,though with conflicting results.The aim of this study was to quantitatively summarize the evidence for CYP4A 11 T8590C polymorphism and hypertension risk.Methods Electronic search of PubMed and the Chinese Biomedicine database was conducted to select studies.Casecontrol studies containing available genotype frequencies of T8590C were chosen,and odds ratio (OR) with 95% confidence interval (CI) was used to assess the strength of this association.Results Seven case-control studies,including 3 295 cases and 3 192 controls,were identified.The meta-analysis,stratified by ethnicity,showed that individuals with the C allele carriers (CC+CT) had increased risk of hypertension in over all (OR=1.184,95% CI:1.063-1.319,P=0.002) and in others (OR=1.217,95% CI:1.045-1.419,P=0.012).The results among Asians did not suggest an association (OR=1.152,95% CI:0.990-1.342,P=0.068).A symmetric funnel plot,the Egger's test (P=0.863),and the Begg test (P=0.393) were all suggestive of the lack of publication bias.Conclusions This meta-analysis suggests the CYP4A11 T8590C polymorphism may be a risk factor for hypertension.Future well-designed large studies might be necessary to validate this association in different populations incorporated with environmental factors in the susceptibility of hypertension.

    Objective: To investigate the effects of mitochondrial DNA (mtDNA) copy number in peripheral blood and related factors on the risk of hypertension in coal miners. Methods: A case-control study was conducted in 378 coal miners with hypertension and 325 healthy coal miners recruited from Datong Coal Mine Group. A standard questionnaire was used to collect their general information, such as demographic characteristics, habits and occupational history. Fluorescence quantitative PCR was performed to detect the copy number of mtDNA. Logistic regression model was applied for identifying the related risk factors of hypertension and analyzing the interaction between mtDNA copy number and risk factors. Results: The prevalence of hypertension of high mtDNA copy number was lower than mtDNA copy numberin 0-5.67 group, but the difference was not statistically significant (P=0.414). Alcohol drinking (OR=1.80, 95% CI: 1.26-2.56), family history of hypertension (OR=1.74, 95% CI: 1.20- 2.50), work shifts (OR=0.69, 95% CI: 0.48-0.99), education level (P=0.012) and family monthly income level (P=0.001) were related to the prevalence of hypertension. There were potential interactions between mtDNA copy number and alcohol drinking, family monthly income level, family history of hypertension, respectively. Alcohol drinking was a risk factor for hypertension [1.77 (1.25-2.50)]. Potential interactions between mtDNA copy number and alcohol drinking reduced the risk of hypertension (OR=1.20, 95% CI: 1.07-1.35). Family history of hypertension was a risk factor for hypertension [1.81(1.26-2.59)]. Potential interactions between mtDNA copy number and family history of hypertension reduced the risk of hypertension (OR=1.24, 95%CI: 1.09-1.41). Family monthly income level was a protect factor for hypertension [0.55(0.46-0.66)]. Potential interactions between mtDNA copy number and family monthly income level increased the protection role of hypertension (OR=0.90, 95% CI: 0.86-0.94). Conclusion: mt

    Metabolic disorders are widely described in patients after liver transplantation (LTx). Arterial hypertension, diabetes mellitus and obesity incidence and risk factors were assessed in 144 post-LTx patients at least one year after transplantation (59% male; median age 54 y; median time since transplantation 4 y). Risk factors were assessed using logistic regression analysis according to demographic, socioeconomic, lifestyle, clinical, anthropometric and dietetic variables. The incidence of hypertension was 18.9%; diabetes, 14.0% and obesity, 15.9%. Risk factors for the incidence of hypertension were abdominal obesity (OR: 2.36; CI: 1.02-5.43), family history of hypertension (OR: 2.75; CI: 1.06-7.19) and cyclosporine use (OR: 3.92; CI: 1.05-14.70). Risk factor for incidence of diabetes were greater fasting glucose levels (mg/dL) pre-LTx (OR: 1.04; CI: 1.01-1.06) and on the diagnosis of alcoholic cirrhosis as an indication of LTx (OR: 2.54; CI: 0.84-7.72). The incidence of obesity after LTx was related to lower milk consumption (mL) (OR: 1.01; CI: 1.001-1.01; P obesity. Furthermore, the incidences of these disorders were related to immunosuppressive therapy and have risk factors that are common in the general population. Copyright © AULA MEDICA EDICIONES 2013.

    To analyze the trends in blood pressure (BP), and the prevalence, awareness, treatment and control of hypertension and associated factors in Chinese adults from 1991 to 2011. On the basis of the longitudinal data of China Health and Nutrition Survey, 75 526 records of 24 410 adults were selected according to the eligibility criteria. The age-standardized levels of SBP, DBP, prevalence, awareness, treatment and control of hypertension were calculated by sex and age group within each year. Generalized estimating equation was employed to investigate the associations between demographic factors and status of hypertension, awareness, treatment and control. From 1991 to 2011, the BP level elevated (SBP 120.0-124.5 mmHg, DBP 76.7-79.3 mmHg) and the prevalence of hypertension increased from 23.4 to 28.6%. The increasing levels of BP and hypertension prevalence were more apparent among men and older patients. The rates of hypertension awareness, treatment and control also increased while kept at low levels. Factors such as age, sex, smoking habit, drinking habit, household income, health insurance, BMI, residential region, marital status, educational level and nationality were significantly associated with the status of hypertension, awareness, treatment and control. The BP level and hypertension prevalence have increased among Chinese adults in recent years. However, levels of hypertension awareness, treatment and control were quite low. To reduce the disease burden of the hypertension, improvements in health education programs, detection and treatment strategies are warranted.

    Hypertension is the most common adverse effect of the inhibitors of vascular endothelial growth factor (VEGF) pathway-based therapy (VEGF pathway inhibitors therapy, VPI therapy) in cancer patients. VPI includes monoclonal antibodies against VEGF, tyrosine kinase inhibitors, VEGF Traps, and so-called aptamers that may become clinically relevant in the future. All of these substances inhibit the VEGF pathway, which in turn causes a decrease in nitric oxide (NO) and an increase in blood pressure, with the consequent development of hypertension and its final events (e.g., myocardial infarction or stroke). To our knowledge, there is no current study on how to provide an optimal therapy for patients on VPI therapy with hypertension. This review summarizes the roles of VEGF and NO in vessel biology, provides an overview of VPI agents, and suggests a potential treatment procedure for patients with VPI-induced hypertension.

    Pelvic organ prolapse (POP) is an important problem for women with multifactorial etiology. This study aims to determine the role of hypertension (HT) and diabetes mellitus (DM) in POP. The study included 586 women admitted to Bulent Ecevit University Hospital between September 2013 and April 2015 for hysterectomy, comprising 186 patients with POP and 400 patients without. The demographic characteristics, age, body mass index (BMI), obstetrical history, type of delivery, associated medical diseases, and benign gynecological diseases were recorded. HT, DM, or both together were particularly considered as coexisting medical diseases. Median gravida, parity, and live birth numbers were significantly higher in POP patients (4 vs. 3, 3 vs. 2, and 3 vs. 2 respectively, p0.05). There was a significant difference between groups regarding comorbid diseases (p<0.001). Logistic regression analysis for risk factors of POP revealed age, BMI, vaginal parturition, and co-morbidity with HT+DM together significantly increased POP risk (p<0.05). HT+DM together significantly increased risks with OR of 1.9 (1.1-3.16). In addition to multiple factors increasing POP risk, comorbidities as HT+DM together should be considered as risk factors. Patients with these comorbidities should be encouraged to change their lifestyles to prevent POP. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Hypertension in youth is increasing, but there is a dearth of data about the knowledge of risk factors in this age group. To assess the knowledge of risk factors of hypertension among university students and associate it with the blood pressure, physical activity, family history of cardiovascular disease (CVD), and sociodemographic variables. A cross-sectional survey among students enrolled in the first year, in the four academic programs, with the use of a validated, self-administered questionnaire on physical activity in the past 30 days and knowledge of risk factors of hypertension. A score of 6 on 11 was considered as good knowledge for modifiable risk factors. Blood pressure was also measured. The data was analyzed using PASW-17, Chi square test, and binary logistic regression analysis was done. Of the 110 participants, 69.2% were coffee consumption 35.5%, physical inactivity 47%, and oral contraceptives 13.6%. Half the group did not consider a family history of CVD as a risk factor, 60% did not consider older age as a risk factor, and 88% did not think male gender was a risk factor. Knowledge of modifiable risk factors was better than that of non-modifiable risk factors. Although nationality, course of study, raised blood pressure, and history of diabetes showed significant association with good knowledge, their net effect was not significant by the Adjusted Odd's Ratio. The study identified some gaps in knowledge regarding both modifiable and non-modifiable risk factors of hypertension among students. A larger study would enable health promotion activities tailored to the needs of this age group.

    Objective:The aim of this study is to assess the correlation between traditional cardiovascular risk factors and elevated plasma tHcy level in Nigerian hypertensive. Methods: Thirty-six hypertensive patients were recruited with 36 age and sex-matched controls. The age, sex and anthropometric measurements including height, weight and body mass index (BMI) were taken. Plasma total cholesterol, low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), tri-glycerides and tHey were analyzed. The results of the two groups were compared. Results: The mean total cholesterol and LDL-C were significantly higher in the subjects than in the controls (P=0.01 and 0.03 respectively). On the other hand, means of HDL-C and triglycerides were not significantly different between the two groups (P = 0.06 and O. 68 respectively). Mean total plasma tHey was (12. 95±4.9)μmol/L in hypertensive patients when compared with (11.29±3.6)μmol/L in the controls (P =0.09), however the mean they was significantly higher in hypertensive patients who had stroke or myocardial infarction than those without these complications (one way Anova F = 3.63, P =0.04). Significant positive correlation was seen between tHcy and systolic blood pressure, diastolic blood pressure, BMI and LDL-C. Conclusion:The study suggests that elevated plasma tH-ey may predict occurrence of cardiovascular complications in hypertensive individuals.

    Objective. The objective of the study was to assess the serum vascular endothelial growth factor (VEGF) levels in peripheral blood of patients with pregnancy-induced hypertension (PIH) and find association between serum VEGF levels and PIH. Methods. Thirty-five PIH subjects, 35 normal pregnant females, and 20 normal healthy females were included in the study. Detailed history, clinical examination, and relevant biochemical parameters were assessed; serum VEGF levels were estimated using Double-antibody enzyme-linked immunosorbent assay. Results. The study groups were found to be age matched (p = 0.38). VEGF level in the pregnancy-induced hypertensive group (median = 109.19 (3.38 ± 619)) was significantly higher than the normal pregnant (median = 20.82 (1.7–619)) and control (median = 4.92 (1.13–13.07)) group and the difference between these three groups was significant (p < 0.0001). The 3 groups are found to be significantly different in terms of RBS (p = 0.01), urea (p < 0.0001), creatinine (p = 0.0005), AST (p = 0.0032), ALT (p = 0.0007), total protein (p = 0.0004), albumin (p < 0.0001), calcium (p = 0.001), and sodium (p = 0.02), while no statistically significant difference was found between total bilirubin (p = 0.167), direct bilirubin (p = 0.07), uric acid (p = 0.16), and potassium (p = 0.14). Conclusion. Significantly higher levels of serum VEGF were noted in PIH subjects compared to normal pregnant and control subjects. PMID:28133548

    To analyze the incidence, risk factors, and time course of intraocular pressure elevation after intravitreal dexamethasone implant (Ozurdex). The medical charts of 421 consecutive eyes (361 patients) receiving one or more Ozurdex implant between October 2010 and February 2015 were reviewed retrospectively. Ocular hypertension was defined as intraocular pressure of at least 25 mmHg or an increase of at least 10 mmHg from baseline. The main indications for treatment were retinal vein occlusion (34%), diabetic macular edema (30%), postsurgical macular edema (17%), uveitis (14%), and other etiologies (5%). Among 1,000 intravitreal injections, ocular hypertension was recorded for 28.5% of injected eyes over a mean follow-up period of 16.8 months (3-55). Intraocular pressure-lowering medication was required for 31% of eyes. Only three eyes with preexisting glaucoma required filtering surgery to manage postinjection intraocular pressure elevation. Early retreatment between the third and fourth month does not increase the risk of intraocular pressure elevation. Younger age, male sex, Type 1 diabetes, preexisting glaucoma treated with dual or triple therapy, and a history of retinal vein occlusion or uveitis were significant risk factors for ocular hypertension after dexamethasone implant injection (P hypertension after Ozurdex implant were generally transient and successfully managed with topical treatment. An analysis of the risk factors may help to determine the risk-benefit ratio for individual patients treated with dexamethasone implants.

This was a single centre retrospective study in 74 adult TS patients (age 29.41 ± 8.91 years) who underwent a routine cardiac MRI. Patients were assigned to the hypertensive group (N = 31) if blood pressure exceeded 140/90 mmHg and/or if they were treated with antihypertensive medication. Aortic arch morphology was evaluated on MRI images and initially assigned as normal (N = 54) or abnormal (N = 20), based on the curve of the transverse arch and the distance between the left common carotid-left subclavian artery. We additionally used a new more objective method to describe aortic arch abnormality in TS by determination of the relative position of the highest point of the transverse arch (AoHP). Logistic regression analysis showed that hypertension is significantly and independently associated with age, BMI and abnormal arch morphology, with a larger effect size for the new AoHP method than for the classical method. TS patients with hypertension and abnormal arch morphology more often had dilatation of the ascending aorta. There is a significant association between abnormal arch morphology and hypertension in TS patients, independent of age and BMI, and not related to other structural heart disease. We suggest that aortic arch morphology should be included in the risk stratification for hypertension in TS and propose a new quantitative method to express aortic arch morphology.

    With the increasing knowledge about the antioxidant potential of many micronutrients such as zinc and vitamin C, their roles in oxidative stress related health disorders have been postulated. This study therefore investigated low micronutrient status as a predisposing factor for hypertension in a traditionally lacto-vegetarian population like Indians. Micronutrient profile was assessed in 109 hypertensives with age-gender-socio-economic status matched 115 healthy normotensives (30-58 years of age). Food intakes were estimated through a semi-quantitative food frequency questionnaire. Nutrient intakes were then evaluated by previous estimates of cooked foods from our laboratory. Systolic and diastolic blood pressure (SBP, DBP), age, weight, height, waist and hip circumference, occupation, physical activity, smoking habits were recorded. Fasting blood samples were analyzed for hemoglobin, serum level of glucose, triglycerides, total cholesterol, HDL, ceruloplasmin, plasma level of ascorbic acid, folic acid, retinol, erythrocyte glutathione reductase activity coefficient (EGRAC) and erythrocyte membrane zinc. There were no significant differences between protein, fat intakes of normal and hypertensive individuals, though intakes of men were higher than those of women (p 0.2) in these subjects. Conditional logistic regression analysis indicated that intakes of vitamin C, folic acid and zinc were associated with 18% (OR = 1.18, 95% CI:1.08, 1.26), 51% (OR = 1.51, 95% CI 0.94, 2.1) higher odds for hypertension, and 3% lower odds for hypertension (OR = 0.97, 95% CI 0.92, 1.01), respectively. Mean plasma vitamin C and folic acid were significantly higher (p < 0.01), and serum ceruloplasmin and erythrocyte membrane zinc were marginally higher (p = 0.07) in normal than hypertensive subjects. In multivariate linear regression analyses, plasma vitamin C, serum ceruloplasmin and erythrocyte membrane zinc were negatively associated with SBP (p = 0.00001) and plasma vitamin C was

    Little information is available regarding hypertension, treatment, and control in urban population of Latin America. We aimed to compare blood pressure (BP) distribution, hypertension prevalence, treatment, and control in seven Latin American cities following standard methodology. The Cardiovascular Risk Factor Multiple Evaluation in Latin America (CARMELA) study was a cross-sectional, epidemiologic study assessing cardiovascular risk factors using stratified multistage sampling of adult populations (aged 25-64 years) in seven cities: Barquisimeto (Venezuela; n = 1848); Bogotá (n = 1553); Buenos Aires (n = 1482); Lima (n = 1652); Mexico City (n = 1720); Quito (n = 1638); and Santiago (n = 1655). The prevalence of hypertension and high normal BP were determined based on 2007 European Society of Hypertension and European Society of Cardiology definitions. BP increased with age in men and women; pulse pressure increased mainly in the upper age group. The hypertension prevalence ranged from 9% in Quito to 29% in Buenos Aires. One-quarter to one-half of the hypertension cases were previously undiagnosed (24% in Mexico City to 47% in Lima); uncontrolled hypertension ranged from 12% (Lima) to 41% (Mexico City). High normal BP was also evident in a substantial number of each city participants (approximately 5-15%). Majority of population has other cardiovascular risk factors despite hypertension; only 9.19% of participants have no risk factors apart from hypertension. From 13.4 to 44.2% of the populations of seven major Latin American cities were hypertensive or had high normal BP values. Most hypertensive patients have additional risk factors. Public health programs need to target prevention, detection, treatment, and control of total cardiovascular risk in Latin America.

    Despite major advances in understanding the pathophysiology of hypertension and availability of effective and safe antihypertensive drugs, suboptimal blood pressure (BP) control is still the most important risk factor for cardiovascular mortality and is globally responsible for more than 7 million deaths annually. Short-term and long-term BP regulation involve the integrated actions of multiple cardiovascular, renal, neural, endocrine, and local tissue control systems. Clinical and experimental observations strongly support a central role for the kidneys in the long-term regulation of BP, and abnormal renal-pressure natriuresis is present in all forms of chronic hypertension. Impaired renal-pressure natriuresis and chronic hypertension can be caused by intrarenal or extrarenal factors that reduce glomerular filtration rate or increase renal tubular reabsorption of salt and water; these factors include excessive activation of the renin-angiotensin-aldosterone and sympathetic nervous systems, increased formation of reactive oxygen species, endothelin, and inflammatory cytokines, or decreased synthesis of nitric oxide and various natriuretic factors. In human primary (essential) hypertension, the precise causes of impaired renal function are not completely understood, although excessive weight gain and dietary factors appear to play a major role since hypertension is rare in nonobese hunter-gathers living in nonindustrialized societies. Recent advances in genetics offer opportunities to discover gene-environment interactions that may also contribute to hypertension, although success thus far has been limited mainly to identification of rare monogenic forms of hypertension. © 2012 American Physiological Society

    Full Text Available Members of the Police Mobile Brigade (Brimob can suffer from hypertension which is related to work stressors and other risk factors. This study aimed to identify the relationship between work stressors and other hypertensive risk factors. The subjects of this cross-sectional study were members of the Brimob undergoing their periodic medical check-up during July-October 2007. A subject was hypertensive if systolic blood pressure (SBP was 140 mmHg or higher, or diastolic (DBD 90 mmHg, or higher or taking antihypertensive drugs. Normal subjects were those who had SBP less than 120 mmHg and DBP less than 80 mmHg, and have never been diagnosed with hypertension. A number of 336 Brimobs aged 21 to 51 years participated in this study, 111 had high blood pressure and 79 had normal blood pressure. Hypertension was found to be related to excessive body weight and qualitative work overload. Age, work, lifestyle, history of diabetes, hypertension in the family, and other work stressors were not found to increase the risk of hypertension. Medium to high level qualitative work overload had a two-fold risk for hypertension [relative risk adjusted (RRa = 2.00; 95% confidence interval (CI = 0.97-4.14; p = 0.060]. Overweight subjects had 48% increased risk to hypertension (RRa = 1.48; 95% CI = 0.98-2.22. Obese subjects had a two-fold risk of being hypertensive (RRa = 2.21; 95%CI = 1.51 - 3.14. Qualitative work overload and obesity increased the risk of hypertension. These risk factors should therefore be controlled.

    Full Text Available Abstract Background In a previous study of the Hypertension Genetic Epidemiology Network (HyperGEN we have shown that metabolic syndrome (MetS risk factors were moderately and significantly associated with echocardiographic (ECHO left ventricular (LV phenotypes. Methods The study included 1,393 African Americans and 1,133 whites, stratified by type 2 diabetes mellitus (DM status. Heritabilities of seven factor scores based on the analysis of 15 traits were sufficiently high to pursue QTL discovery in this follow-up study. Results Three of the QTLs discovered relate to combined MetS-ECHO factors of "blood pressure (BP-LV wall thickness" on chromosome 3 at 225 cM with a 2.8 LOD score, on chromosome 20 at 2.1 cM with a 2.6 LOD score; and for "LV wall thickness" factor on chromosome 16 at 113.5 with a 2.6 LOD score in whites. The remaining QTLs include one for a "body mass index-insulin (BMI-INS" factor with a LOD score of 3.9 on chromosome 2 located at 64.8 cM; one for the same factor on chromosome 12 at 91.4 cM with a 3.3 LOD score; one for a "BP" factor on chromosome 19 located at 67.8 cM with a 3.0 LOD score. A suggestive linkage was also found for "Lipids-INS" with a 2.7 LOD score located on chromosome 11 at 113.1 cM in African Americans. Of the above QTLs, the one on chromosome 12 for "BMI-INS" is replicated in both ethnicities, (with highest LOD scores in African Americans. In addition, the QTL for "LV wall thickness" on chromosome 16q24.2-q24.3 reached its local maximum LOD score at marker D16S402, which is positioned within the 5th intron of the cadherin 13 gene, implicated in heart and vascular remodeling. Conclusion Our previous study and this follow-up suggest gene loci for some crucial MetS and cardiac geometry risk factors that contribute to the risk of developing heart disease.

    Cardiovascular disease (CVD) has been the number one cause of death since the last three decades in Malaysia and diabetes mellitus and hypertension are considered as major risk factors. A study to reduce risk factors for cardiovascular diseases in the community (PIKOM) through education and lifestyle changes was undertaken. The study population was from four different areas in Peninsular Malaysia - Kota Bharu and Bachok in Kelantan ; Raub in Pahang; Gunung Besout in Perak and Felda Palong in Negri Sembilan. The subjects invited to participate in this study ware aged between 30 - 65 years, did not have any debilitating illnesses and no known history of diabetes mellitus, hypertension or cardiovascular disease. Subjects were asked to come to the local clinic in a fasting state and after physical examination, blood was taken for plasma glucose and lipids. Oral glucose tolerance test (OGTT) was then performed. A total of 4,121 subjects participated in the study. The proportion of subjects with diabetes mellitus was highest in Felda Palong area (20.3%) and lowest in Raub area (7.1%). The proportion of subjects with hypertension was also highest in Felda Palong area (38.6%) and lowest in Raub area (29.1%). This could be attributable to the subjects in Felda Palong having the highest mean Body Mass Index (BMI) and Waist-to-Hip Ratio (WHR). There were significant associations between diabetes and hypertension with age and obesity. Subjects with diabetes mellitus and hypertension also had the highest mean age, BMI, WHR and plasma cholesterol.In conclusion, the proportion of patients with risk factors for CVD was high and intervention studies through education and lifestyle changes were being carried out to see their effectiveness.

    Like most countries in sub-Saharan Africa, hypertension contributes substantially to morbidity and mortality in Ghana, yet nationally representative studies that examine the odds of becoming hypertensive among Ghanaians are conspicuously missing. We aimed to fill this void in the literature. The data used for analysis came from the first wave of the Study on Global Ageing and Adult Health (SAGE), collected in Ghana from January 2007 to December 2008 by the World Health Organization (WHO). A total of 5573 respondents were sampled for the study. Random-effects C-log-log models were employed in examining socio-economic, lifestyle and psychosocial factors on the odds of becoming hypertensive in Ghana. Separate models were run for male and females. Results indicated there were strong significant associations between socio-economic, lifestyle and psychosocial factors on the likelihood of becoming hypertensive, among Ghanaian men and women. Compared with the poorest, Ghanaians from wealthy households were significantly more likely to be hypertensive. Educated women, as compared with the uneducated, were also more likely to be hypertensive. Ghanaians who engaged in vigorous or intensive activities continuously, for at least 10 minutes, were significantly less likely to be hypertensive, compared to those who did not. Happier men had lower odds of becoming hypertensive, and depressed women had increased odds of reporting they were hypertensive.

    Hypertension in children is common, and the prevalence of primary hypertension is increasing with the obesity epidemic and changing dietary choices. Careful measurement of blood pressure is important to correctly diagnose hypertension, as many factors can lead to inaccurate blood pressure measurement. Hypertension is diagnosed based on comparison of age-, sex-, and height-based norms with the average systolic and diastolic blood pressures on three separate occasions. In the absence of hypertensive target organ damage (TOD), stage I hypertension is managed first by diet and exercise, with the addition of drug therapy if this fails. First-line treatment of stage I hypertension with TOD and stage II hypertension includes both lifestyle changes and medications. First-line agents include angiotensin-converting enzyme (ACE) inhibitors, thiazide diuretics, and calcium-channel blockers. Hypertensive emergency with end-organ effects requires immediate modest blood pressure reduction to alleviate symptoms. This is usually accomplished with IV medications. Long-term reduction in blood pressure to normal levels is accomplished gradually. Specific medication choice for outpatient hypertension management is determined by the underlying cause of hypertension and the comparative adverse effect profiles, along with practical considerations such as cost and frequency of administration. Antihypertensive medication is initiated at a starting dose and can be gradually increased to effect. If ineffective at the recommended maximum dose, an additional medication with a complementary mechanism of action can be added.

    Full Text Available The objective was to evaluate the frequency of cardiovascular risk factors and hypertension in patients with rheumatoid arthritis depending on body weight. The study involved 100 patients with rheumatoid arthritis and stably selected therapy for more than 6 months at the age from 45 to 65 years (mean age 53,19 ± 5,40 years. Traditional cardiovascular risk was assessed, taking into account risk factors by SCORE scale and amended for patients with RA. The levels of total cholesterol, triglycerides, C-reactive protein, serum creatinine, body mass index, body area index were determined. Arterial hypertension was diagnosed in 41 (41% patients with rheuma¬toid arthritis and was associated with traditional risk factors (age, obesity, rheumatoid factor, hyperuricemia and the duration of glucocorticoid therapy. Obesity and excess body mass occurred in the majority of patients with rheumatoid arthritis, herewith the highest level of inflammation indicators and risk of cardiovascular events was in overweight patients. Obesity was associated with duration of rheumatoid arthritis, the activity of the inflammatory process, the duration of glucocorticoids taking. It is found that the traditional SCORE scale does not fully reflect the risk of cardiovascular events in rheumatoid arthritis. Identification of hypertension and obesity increases the information content of the risk assessment of cardiovascular events in rheumatoid arthritis.

    The purpose of this study is the evaluation of women's exposure to stress-inducing factors at work, definition of a scale of the problem, as well as assessment of the impact of professional work on the value of arterial pressure. The research was conducted on four professional groups of women: working in agriculture, working as clerks, seamstresses, as well as those working as medical representative in the period from August- September 2008 in the Lublin region. A total number of 416 women was examined, ages ranging from 30-40, who had not been previously treated due to arterial hypertension. The women under examination had their arterial blood pressure measured twice on a working day at 08:00 and at 14:00. The values of measurements were averaged. The research tool was also the standardised Questionnaire for Subjective Work Evaluation. The raw result was obtained on the basis of summing up all the points, which were afterwards transformed into 10 standard values. The general result was given in 10 standard values, whereas the results of stress factors were quoted as mean results of raw values and were referred to results defined as high for a given factor. The results obtained were statistically analysed on the basis of t-Student test. The significance level adopted was phigh general level of stress was noted among the group of women working in agriculture, in pharmaceutical companies, as well as among those who perform physical work (seamstresses). The intensification of stress at a workplace had a considerable impact on the value of arterial pressure among the group of woman medical representatives, as well as among the group of woman office workers. No significant dependencies were concluded between socio-demographic variables and the general level of exposure to intensified stress in the examined professional groups. The above research confirms the need for further examination of the working environment of women and its impact on health. Obviously, attempts

    Full Text Available Context: Hypertension in youth is increasing, but there is a dearth of data about the knowledge of risk factors in this age group. Aims: To assess the knowledge of risk factors of hypertension among university students and associate it with the blood pressure, physical activity, family history of cardiovascular disease (CVD, and sociodemographic variables. Materials and Methods: A cross-sectional survey among students enrolled in the first year, in the four academic programs, with the use of a validated, self-administered questionnaire on physical activity in the past 30 days and knowledge of risk factors of hypertension. A score of 6 on 11 was considered as good knowledge for modifiable risk factors. Blood pressure was also measured. The data was analyzed using PASW-17, Chi square test, and binary logistic regression analysis was done. Results: Of the 110 participants, 69.2% were < 20 years of age, 76.4% were females, and 40% were Arabs. Stress, high cholesterol, obesity, and smoking were identified as risk factors by 75.5, 73.6, 77.6, and 71.8%, respectively; 69.1% considered high salt intake and 62.7% considered high calorie diet as risk factors. Energy drink was considered as a risk factor by 64.5%, coffee consumption 35.5%, physical inactivity 47%, and oral contraceptives 13.6%. Half the group did not consider a family history of CVD as a risk factor, 60% did not consider older age as a risk factor, and 88% did not think male gender was a risk factor. Knowledge of modifiable risk factors was better than that of non-modifiable risk factors. Although nationality, course of study, raised blood pressure, and history of diabetes showed significant association with good knowledge, their net effect was not significant by the Adjusted Odd′s Ratio. Conclusions: The study identified some gaps in knowledge regarding both modifiable and non-modifiable risk factors of hypertension among students. A larger study would enable health promotion activities

    Hypertension is an emerging public health problem in Sub Saharan Africa (SSA) and urbanization is considered to favor its emergence. Given a paucity of information on hypertension and associated risk factors among urban slum dwellers in SSA, we aimed to characterize the distribution of risk factors for hypertension and investigate their association with hypertension in an urban slum in Kenya. We conducted a community based cross-sectional survey among adults 35 years and older living in Kibera slum Nairobi, Kenya. Trained interviewers collected data on socio demographic characteristics and self reported health behaviours using modified World Health Organization stepwise surveillance questionnaire for chronic disease risk factors. Anthropometric and blood pressure measurements were performed following standard procedures. Multiple logistic regression was used for analysis and odds ratios with 95 % confidence intervals were calculated to identify risk factors associated with hypertension. A total of 1528 adults were surveyed with a mean age of 46.7 years. The age-standardized prevalence of hypertension was 29.4 % (95 % CI 27.0-31.7). Among the 418 participants classified as hypertensive, over one third (39.0 %) were unaware they had hypertension. Prevalence of current smoking and alcohol consumption was 8.5 and 13.1 % respectively. Over one quarter 26.2 % participants were classified as overweight (Body Mass Index [BMI] ≥25 to ≤29.9 kg/m(2)), and 17 % classified as obese (BMI ≥30 kg/m(2)). Overweight, obesity, current smoking, some level of education, highest wealth index, moderate physical activity, older age and being widowed were each independently associated with hypertension. When fit in a multivariable logistic regression model, being a widow [AOR = 1.7; (95 % CI, 1.1-2.6)], belonging to the highest wealth index [AOR = 1.6; (95 % CI, 1.1-2.5)], obesity [AOR = 1.8; 95 % CI, 1.1-3.1)] and moderate physical activity [AOR = 1.9; (95 % CI

    SUMMARY Vascular endothelial growth factor inhibitors (VEGFi) are known to cause hypertension and renal injury that severely limits their use as an anticancer therapy. We hypothesized that the angiotensin-converting enzyme inhibitor captopril not only prevents hypertension, but also decreases renal injury caused by the VEGFi sorafenib.Rats were administered sorafenib (20 mg/kg per day) alone or in combination with captopril (40 mg/kg per day) for 4 weeks. Sorafenib administration increased blood pressure, which plateaued by day 10.Concurrent treatment with captopril for 4 weeks resulted in a 30 mmHg decrease in blood pressure compared with sorafenib alone (155 ± 5 vs 182 ± 6 mmHg, respectively; P captopril treatment reduced albuminuria by 50% compared with sorafenib alone (20 ± 8 vs 42 ± 9 mg/day, respectively; P captopril-treated rats administered sorafenib. Renal autoregulatory efficiency was determined by evaluating the afferent arteriolar constrictor response to ATP. Sorafenib administration attenuated the vasoconstriction to ATP, whereas concurrent captopril treatment improved ATP reactivity.In conclusion, captopril attenuated hypertension and renal injury and improved renal autoregulatory capacity in rats administered sorafenib. These findings indicate that captopril treatment, in addition to alleviating the detrimental side-effect of hypertension, decreases the renal injury associated with anticancer VEGFi therapies such as sorafenib.

    Full Text Available The study examined prevalence, awareness, treatment and control of hypertension (HTN, and associated factors and to evaluate the trend in hypertension between 2009 (period 2 and 1994–1998 (period 1. A national sample of 4117 adults aged 25 years and older was selected. Prevalence rate of HTN (SBP ≥ 140 or DBP ≥ 90 or on antihypertensive therapy was 32.3% and was higher than the 29.4% prevalence rate reported in period 1. Prevalence rate was significantly higher among males, older age groups, least educated, obese, and diabetics than their counterparts. The rate of awareness among hypertensives was 56.1% and was higher than the 38.8% rate reported form period 1 data. Awareness was positively associated with age, smoking, and diabetes for both men and women, and with level of education and body mass index for men. Rate of treatment for HTN among aware patients was 63.3% and was significantly higher than the 52.8% rate reported in period1. Control rate of HTN among treated hypertensives was 39.6%; significantly higher than the 27.9% control rate in period 1. Control of HTN was positively associated with age but only for women. In conclusion, HTN is still on the rise in Jordan, and levels of awareness and control are below the optimal levels.

Previously undiagnosed diabetes [fasting plasma glucose (FPG ≥ 7.0 mmol/l] and IFG (6.1-6.9 mmol/l were defined based on FPG concentration. Previously diagnosed diabetes was determined on the basis of self-report. Total diabetes included both previously diagnosed diabetes and previously undiagnosed diabetes. RESULTS: The prevalence of previously diagnosed diabetes, undiagnosed diabetes, and IFG were 3.4%, 9.8%, and 14.1%, respectively. About 74.2% of the participants with diabetes had not previously been diagnosed. In the multivariable logistic-regression model, older age, men, antihypertensive treatment, obesity (BMI ≥ 25 kg/m(2, abdominal obesity (waist circumference ≥ 90 cm for men and ≥ 80 cm for women, non-current smoking, a family history of diabetes, higher heart rate, lower physical activity levels, and inland residence (versus coastal were significantly associated with both total diabetes and previously undiagnosed diabetes. Furthermore, methylene- tetrahydrofolate reductase (MTHFR 677 TT genotype was an independent associated factor for total diabetes, and current alcohol drinking was an independent associated factor for previously undiagnosed diabetes. At the same time, older age, men, abdominal obesity, non-current smoking, current alcohol drinking, a family history of diabetes, higher heart rate, and inland residence (versus coastal were important independent associated factors for IFG. CONCLUSION: In conclusion, we found a high prevalence of diabetes in Chinese hypertensive adults. Furthermore, about three out of every four diabetic adults were undiagnosed. Our results suggest that population-level measures aimed at the prevention, identification (even if

    Full Text Available The clustering of cardio-metabolic risk factors, either when called metabolic syndrome (MetS or not, substantially increases the risk of cardiovascular disease (CVD and causes mortality. One of the possible mechanisms for this clustering's adverse effect is an increase in arterial stiffness (AS, and in high central aortic blood pressure (CABP, which are significant and independent CVD risk factors. Arterial hypertension was connected to AS long ago; however, other MetS components (obesity, dyslipidaemia, dysglycaemia or MetS associated abnormalities not included in MetS diagnostic criteria (renal dysfunction, hyperuricaemia, hypercoaglutability, menopause, non alcoholic fatty liver disease, and obstructive sleep apnea have been implicated too. We discuss the evidence connecting these cardio-metabolic risk factors, which negatively affect AS and finally increase CVD risk. Furthermore, we discuss the impact of possible lifestyle and pharmacological interventions on all these cardio-metabolic risk factors, in an effort to reduce CVD risk and identify features that should be taken into consideration when treating MetS patients with or without arterial hypertension.

    Full Text Available Objectives  In this study, the relationships of residue hematoma volume to brain edema and inflammation factors were studied after intracerebral hematoma was evacuated with a frameless stereotactic aspiration. Methods  Eighty-nine patients with hypertensive intracerebral hemorrhage (ICH were treated by frameless stereotactic aspiration. According to residual volume of the hematoma, the patients were divided into gross-total removal of hematoma (GTRH (≤5ml and sub-total removal of hematoma (STRH (≥10ml groups after the operation. The pre-operative and postoperative data of the patients were compared between the two groups. The pre-operative data included age, sex, hematoma volume, time interval from the ictus to the operation, and Glasgow Coma Scale (GCS scores. The post-operative information included edema grade, level of thromboxane B2 (TXB2, 6-keto-prostaglandin F1α(6-K-PGF1α, tumor necrosis factor-α(TNF-α and endothelin (ET in hematoma cavity or cerebral spinal fluid (CSF. Results  There were 46 patients in GTRH group and 43 in STRH group respectively. There was no statistical difference in the pre-operative data between the two groups. The levels of TXB2, 6-K-PGF1α, TNF-αand ET were significantly lower in the GTRH group than in the STRH group at different post-operative time points. There was a significant difference between the two groups. The post-operative CT scan at different time points showed that the brain edema grades were better in the GTRH group than in the STRH group. Conclusions  GTRH is helpful for decreasing ICH-induced injury to brain tissue, which is related to decreased perihematomal edema formation and secondary injury by coagulation end products activated inflammatory cascade.

    Evidence suggests that modifiable risk factors which can be targeted by prevention are vascular diseases, such as diabetes, midlife hypertension (HTN), midlife obesity, midlife cholesterol, mid- and late-life depression as well as lifestyle factors such as smoking, physical inactivity, and poor diet. A comprehensive search of the National Library of Medicine's PubMed database and Google Scholar was conducted. A combinations of medical subject headings and free text words that included search terms related to the exposure (e.g., prevalence, HTN, raised BP, high BP, diabetes, high blood sugar, DM, India, state), were combined with search terms related to the outcomes (e.g., prevalence, disease burden, estimate, dementia, India). The filters included were English for the language category and humans for the study category. The PubMed search initially identified 269 references, and a total of 204 abstracts were screened by inclusion criteria. Full-text assessment of 136 articles on prevalence of dementia resulted in 20 relevant articles from which the different regions of the country were identified. Based on the search conducted according to the regions; 287abstracts of the prevalence of HTN and 577 on the prevalence of diabetes mellitus were screened. There were 43 full-text articles on the prevalence of HTN and diabetes from the regions where the prevalence of dementia was available. Of these potentially relevant articles were 14 in number. Despite the uncertainty in the role, the data analysis, therefore, points to a role in the prevention of HTN and diabetes to prevent dementia.

    In a population-based case-control study of kidney cancer in New South Wales, Australia, data from structured interviews with 489 cases of renal cell cancer (RCC) and 147 cases of renal pelvic cancer (CaRP) diagnosed in 1989 and 1990, and 523 controls from the electoral rolls, confirmed the link between obesity and RCC. In addition, regular consumption of 'diet' pills independently increased the risk for this cancer. A diagnosis of hypertension at least two years before interview raised the risk for RCC, and regular use of beta-blockers, a class of antihypertensive drug, independently increased the risk for RCC and CaRP (risk ratio = 1.5-1.8). No independent effect was found for use of diuretics. Additional information provided by this study includes increased risks associated with kidney injury (RCC, CaRP)--possibly attributed to recall bias--and kidney infection (CaRP), as well as a nonsignificantly raised risk linked with kidney stones (RCC, CaRP) and a significantly reduced risk for RCC in persons giving a history of lower urinary tract infection. No significant association of RCC was found with hormonal factors (age at menarche or menopause; child-bearing; regular use of oral contraceptives or estrogens; hysterectomy or oophorectomy).

    Hypertension is a major contributor to the global non-communicable disease burden. Family history is an important non-modifiable risk factor for hypertension. The present study aims to describe the influence of family history (FH) on hypertension prevalence and associated metabolic risk factors in a large cohort of South Asian adults, from a nationally representative sample from Sri Lanka. A cross-sectional survey among 5,000 Sri Lankan adults, evaluating FH at the levels of parents, grandparents, siblings and children. A binary logistic regression analysis was performed in all patients with 'presence of hypertension' as dichotomous dependent variable and using family history in parents, grandparents, siblings and children as binary independent variables. The adjusted odds ratio controlling for confounders (age, gender, body mass index, diabetes, hyperlipidemia and physical activity) are presented below. In all adults the prevalence of hypertension was significantly higher in patients with a FH (29.3%, n = 572/1951) than those without (24.4%, n = 616/2530) (p hypertension (OR:1.29; 95% CI:1.13-1.47), obesity (OR:1.36; 95% CI: 1.27-1.45), central obesity (OR:1.30; 95% CI 1.22-1.40) and metabolic syndrome (OR:1.19; 95% CI: 1.08-1.30). In all adults presence of family history in parents (OR:1.28; 95% CI: 1.12-1.48), grandparents (OR:1.34; 95% CI: 1.20-1.50) and siblings (OR:1.27; 95% CI: 1.21-1.33) all were associated with significantly increased risk of developing hypertension. Our results show that the prevalence of hypertension was significantly higher in those with a FH of hypertension. FH of hypertension was also associated with the prevalence of obesity, central obesity and metabolic syndrome. Individuals with a FH of hypertension form an easily identifiable group who may benefit from targeted interventions.

    Full Text Available BACKGROUND An elevated arterial pressure is probably the most important public health problem in developing & developed countries. Hypertension is the commonest cardiovascular disorder and one of the major risk factor for cardiovascular mortality. MATERIALS AND METHODS The present study was conducted in rural field practice area of the Department of Community medicine Katihar Medical College, Katihar. A sample of 500 families was selected by systematic sampling technique from all the families registered at Health Centre and all the persons aged 20 years and above residing in these families were selected for the purpose of the study. RESULTS In total 1680 study subjects, 602 persons (35.8% aged 20 years & above were found to be hypertensive. It shows that hypertension increased with increasing age with peak in 60 + years category (65.6%. The prevalence was found to be 66.2% in persons with high salt intake and 31.2% and 20.3% respectively in average and low salt intake. The prevalence of hypertension was 40.3% in non-vegetarians and 34.7% among vegetarians. The prevalence was 48.4% in persons consuming saturated fats, 39.1% in those consuming unsaturated fats and 32.6% in both types of fat consumers. The prevalence of hypertension was 37.9% in those engaged in light physical activity while it was found to be 29.6% in moderate and 28.6% in heavy physical activity. It was found to be 91.2% in obese with while this was 23.4% and 18.9% respectively in normal and underweight. It showed that prevalence of hypertension was 38.3% in occasional, 40.0% in frequent and 73.1% in constant group and only 33.0% in group with no mental stress. CONCLUSION This study shows that the prevalence of hypertension was high in the subjects having low physical activity, High BMI and high saturated fat/salt intake and high level of mental stress.

    The purpose of this study was to determine cardiovascular risk factors in women with a history of hypertensive pregnancy disorders at term (HTP) 2.5 years after pregnancy. In a multicenter cohort study in The Netherlands from June 2008 through November 2010, cardiovascular risk factors were compared between women with a history of HTP (HTP cohort, n = 306) and women with a history of normotensive pregnancies at term (NTP cohort, n = 99). HTP women had participated in a randomized, longitudinal trial assessing the effectiveness of induction of labor in women with hypertensive pregnancy disorders at term. All women were assessed 2.5 years after pregnancy for blood pressure, anthropometrics, glucose, glycosylated hemoglobin, insulin, homeostatic model assessment score, total cholesterol, high-density lipoprotein cholesterol, triglycerides, high-sensitivity C-reactive protein, and microalbumin and metabolic syndrome. After a mean follow-up period of 2.5 years, hypertension (HTP, 34%; NTP, 1%; P HTP, 25%; NTP, 5%; P HTP women compared with NTP women. HTP women had significantly higher systolic and diastolic blood pressure, higher body mass index, and higher waist circumference. Glucose, glycosylated hemoglobin, insulin, homeostatic model assessment score, total cholesterol, triglycerides, and high-sensitivity C-reactive protein levels were significantly higher and high-density lipoprotein cholesterol was significantly lower in HTP women. In women with a history of HTP, hypertension and metabolic syndrome are more common, and they have higher levels of biochemical cardiovascular risk factors 2.5 years after pregnancy.

    Hypertension is a common complication of pregnancy. Preeclampsia, in particular, is associated with substantial risk to both the mother and the fetus. Several risk factors have been recognized to predict risk for preeclampsia. However, at present no biomarkers have sufficient discriminatory ability to be useful in clinical practice, and no effective preventive strategies have yet been identified. Commonly used medications for the treatment of hypertension in pregnancy include methyldopa and labetalol. Blood pressure thresholds for initiating antihypertensive therapy are higher than outside of pregnancy. Women with prior preeclampsia are at increased risk of hypertension, cardiovascular disease, and renal disease.

    Full Text Available Diabetes mellitus and the metabolic syndrome are becoming leading causes of death in the world. Identifying the etiology of diabetes is key to prevention. Despite the similarity in their structures, fructose and glucose are metabolized in different ways. Uric acid, a byproduct of uncontrolled fructose metabolism is known risk factor for hypertension. In the liver, fructose bypasses the two highly regulated steps in glycolysis, glucokinase and phosphofructokinase, both of which are inhibited by increasing concentrations of their byproducts. Fructose is metabolized by fructokinase (KHK. KHK has no negative feedback system, and ATP is used for phosphorylation. This results in intracellular phosphate depletion and the rapid generation of uric acid due to activation of AMP deaminase. Uric acid, a byproduct of this reaction, has been linked to endothelial dysfunction, insulin resistance, and hypertension. We present possible mechanisms by which fructose causes insulin resistance and suggest actions based on this association that have therapeutic implications.

    The prevalence of obesity-related hypertension is high worldwide and has become a major health issue. The mechanisms by which obesity relates to hypertensive disease are still under intense research scrutiny, and include altered hemodynamics, impaired sodium homeostasis, renal dysfunction, autonomic nervous system imbalance, endocrine alterations, oxidative stress and inflammation, and vascular injury. Most of these contributing factors interact with each other at multiple levels. Thus, as a multifactorial and complex disease, obesity-related hypertension should be recognized as a distinctive form of hypertension, and specific considerations should apply in planning therapeutic approaches to treat obese individuals with high blood pressure.

    Hypertension is the leading cause of chronic disease and premature death in the United States. To date, most risk factors for hypertension have been identified at the individual (micro) level. The association of macro-level (area) socioeconomic factors and hypertension prevalence rates in the population has not been studied extensively. We used the 2011 Behavioral Risk Factor Surveillance System to examine whether state socioeconomic status (SES) indicators predict the prevalence of self-reported hypertension. Quintiles of state median household income, unemployment rate among the population aged 16 to 64 years, and the proportion of the population under the national poverty line were used as the proxy for state SES. Hypertension status was determined by the question "Have you ever been told by a doctor, nurse, or other health professional that you have high blood pressure?" Logistic regression was used to assess the relationship between state SES and hypertension with adjustment for individual covariates (demographic and socioeconomic factors and lifestyle behaviors). States with a median household income of $43,225 or less (odds ratio [95% confidence interval] = 1.16 [1.08-1.25]) and states with 18.7% or more of residents living below the poverty line (odds ratio [95% confidence interval] = 1.14 [1.04-1.24]) had a higher prevalence of hypertension than states with the most residents in the most advantageous quintile of the indicators. The observed state SES-hypertension association indicates that area SES may contribute to the burden of hypertension in community-dwelling adults.

    Conflicting evidence exists regarding whether reduced estimated glomerular filtration rate (eGFR) and proteinuria are independent risk factors for stroke and its subtypes in hypertensive patients. This study investigated the association of these renal measures with first incident stroke in adults under treatment for hypertension in China. The study included 19 599 adults aged 45 to 75 years who participated in the China Stroke Primary Prevention Trial. Baseline eGFR was calculated using the Chronic Kidney Disease Epidemiology Collaboration creatinine equation. Proteinuria was assessed by qualitative dipstick urinalysis and in a subset by the quantitative albumin-creatinine ratio method. Cox regression analysis was used to examine the effects of eGFR and proteinuria on the risk of first incident stroke. During a median of 4.5 years of follow-up, a total of 585 first strokes (472 ischemic strokes) were identified. Compared to participants without proteinuria, participants with proteinuria (trace or more by dipstick) had a 35% increased risk of first stroke: the adjusted hazard ratio (HR) (95% CI) was 1.35 (1.09-1.66, P=0.005). The results were robust in subgroup analyses. In a subset with data on proteinuria measured by quantitative albumin-creatinine ratio, a similar association was found. In both independent and combined analyses with proteinuria, eGFR was not significantly associated with stroke. In adults under treatment for hypertension in China, baseline proteinuria measured by dipstick or quantitative albumin-creatinine ratio, but not reduced eGFR, was found to be an independent risk factor for first incident stroke and ischemic stroke. © 2015 The Authors.

    Hypertension (HPT) is the most common condition seen in primary care that can lead to health consequences and death if not detected early and treated appropriately.This study aimed to synthesize the prevalence, awareness, and control of HPT, and investigate the risk factors for HPT in Myanmar.We performed a meta-analysis of observational studies. Relevant studies were searched in electronic databases. The methodological quality of the included studies was assessed in 3 domains: selection bias, measurement bias, and bias related to data analysis. The overall prevalence and proportions was calculated using random-effect model of DerSimonian-Laird method. To identify the risk factors for HPT in Myanmar, we entered the ratio measures of the (adjusted) effect as a log odds ratio (OR) and the standard error of the log OR using generic inverse-variance weighting method. For stability of results, we performed leave-one-study-out sensitivity analysis by omitting individual studies one at a time from the meta-analysis.Seven studies (n = 20,901) were included in this analysis. Overall prevalence of HPT in Myanmar was 22% (95% confidence interval (CI): 14%-31.7%, I: 99.6%), stratified as 21.5% (95% CI: 14.1%-29.9%, I: 98.7%) in men and 22.7% (95% CI: 10.8%-34.6%, I: 99.5%) in women. Overall, prevalence of HPT increased with an advancing age of the participants. The proportions of awareness and controlled HPT were 55% (95% CI: 43%-67%, I: 97.7%) and 11% (95% CI: 6%-15%, I: 93.8%), respectively. A weak but significant association was observed between HPT and alcohol drinking (summary OR: 1.38, 95% CI: 1.14%-1.65, I: 0%) and smoking (summary OR: 1.32, 95% CI: 1.0%-1.74, I: 50%). In sensitivity analysis, when a study that made confirmation of HPT by the former World Health Organization criteria was dropped, the prevalence increased to 26% (95% CI: 20.8%-32.1%, I: 98.1%).HPT was considerably prevalent in Myanmar, while the levels of awareness and controlled HPT were low.

    The 2000 National Health Survey (ENSA 2000) was a probabilistic survey that included more than 45,000 subjects aged between 20 to 69 years old. It was directed to determine the prevalence of non-communicable chronic diseases such as hypertension, diabetes, obesity glucosa, and proteinuria. The survey was weighed with to the National Register of Population (INEGI). The prevalence for hypertension was 30.05%, for diabetes of 10.76%, for obesity 24.4%, abnormal capillary glucose 12.7% and for proteinuria of 9.2%. Using Conjunctive Consolidation Analysis the interrelationship among the non-communicable chronic diseases was demonstrated. The prevalence was directly related with age, and obesity was the most important modifier of the prevalence of non-communicable chronic disease. ENSA 2000 alerts on the urgent need of national strategies to restrain this important national public health problem.

    Normotensive subjects with family history of hypertension (FHT) have been reported to have increased left ventricular mass index and reduced ventricular compliance. Of interest is whether blood pressure variability (BPV), which has been associated with target organ damage, is then part of this complex inherited syndrome? The objectives of this study are to determine whether there are any significant differences in BPV, arterial compliance and humoral factors in subjects with FHT as compared to controls. Thirty-five subjects with self reported FHT and 35 matched controls underwent 24 hour BP monitoring (BR-102, Schiller Inc. Germany). Arterial compliance was measured using systolic pulse wave tonometry (HDI/Pulsewave Cardiovascular Profiling Instrument, Hypertension Diagnostic Inc. USA). None of the subjects were hypertensive or diabetic. Out of these numbers, 25 subjects with FHT and 26 controls had measurements of plasma catecholamines, plasma renin and serum aldosterone. Catecholamines were assayed with high performance liquid chromatography, while both renin and aldosterone measurements were by radioimmunoassay. Subjects with FHT have higher night time BPV. There was no significant difference in arterial compliances between both groups. There were increased level of norepinephrine (NE) in subjects with FHT but epinephrine (E), renin and aldosterone levels were similar in both groups. There were no correlations between NE and BPV but E was negatively associated with daytime and mean arterial systolic BPV. In conclusion subjects with FHT demonstrated a higher night time BPV and NE level as compared to controls.

    Full Text Available The research goal is to investigate the relationship between hemodynamic factors and parameters of remodeling of common carotid arteries. 102 patients with essential hypertension of l-ll stage (49 men, 53 women, average age 47,5±11,2 years, duration of hypertension 7,8±1,5 years have been examined. The study has revealed the relation between blood flow velocity in the common carotid artery (CCA and the parameters of vascular remodeling, depending on the degree of hypertension. With the increase in systolic blood pressure dilation of common carotid arteries has been observed, reducing the rate of blood flow and wall thickness of the intima-media complex, accompanied by increased stiffness of the vascular wall. The increase in systolic blood pressure is accompanied by decrease in the rate of blood flow and wall tension on the endothelium, which contributes to thickness of the intima-media complex and increases the rigidity of the vascular wall

    To evaluate whether the clustering of risk factors, both environmental and genetic, increases the risk of essential hypertension (EH) and the accumulation of risk factors influences the blood pressure level in normotensives. Methods On the basis of a prevalence survey, 501 subjects of Mongolian ethnicity (243hypertensives and 258 normotensives) who were not related to each other were selected to conduct a case-control study.All subjects were interviewed with questionnaires and their blood specimens were collected. Renin gene insertion/deletion (I/D) polymorphism, a new genetic marker, was genotyped with PCR and polyacrylamide gel electrophoresis. Results Overweight, alcohol consumption, and renin gene I/D polymorphism were significant risk factors of EH (P<0.05). The odds ratios (OR) for the number of risk factors were 2.39 (95%CI: 0.98-6.74) for one risk factor, 5.03 (95%CI: 2.06-14.18) for two, and 6.09 (95%CI: 1.85-22.38) for three respectively after adjusting for age and sex. In normotensives, age- and sex-adjusted mean blood pressures increased with more accumulation of risk factors.However, there were no significant differences among the different blood pressure levels according to the number of risk factors (P>0.05). Conclusion Overweight, alcohol consumption, and renin gene I/D polymorphism are risk factors of EH in the Mongolian ethnic population of China. The accumulation of the risk factors causes a sharp increase of the risk of EH.

    [Purpose] The aim of this study was to investigate whether hypertension negatively affects the postural balance control of elderly adults under different sensory conditions. [Subjects and Methods] Fifty-four healthy elderly adults who were residents in a Geriatric Home Care Center were recruited for this study. Height, weight, body mass index and age of the volunteers were recorded. After applying the exclusion criteria, the final study group included 16 hypertensive (HT) and the control group included 10 non-hypertensive (Non-HT) healthy elderly adults. To evaluate postural balance control objectively, the modified Clinical Test of Sensory Interaction on Balance (modified CTSIB) test was performed under four different conditions: 1) eyes open on a stable surface; 2) eyes closed on a stable surface; 3) eyes open on an unstable surface; and 4) eyes closed on an unstable surface. [Results] The postural balance scores (center of gravity sway) of the HT group were slightly higher than those of the Non-HT group under conditions 1 (HT group=0.3°/sec, Non-HT group=0.2°/sec), 2 (HT group=0.8°/sec, Non-HT group=0.4°/sec) and 4 (HT group=4.5°/sec, Non-HT group=3.5°/sec), but no statistically significant differences were found between the HT and Non-HT groups under any sensory condition. [Conclusion] The result of this study indicate that controlled hypertension in elderly adults is not a cause of worse balance performance than controls on stable or unstable surfaces with the eyes open or closed.

    Several polymorphisms in apolipoprotein A1 (APOA1) gene have been associated with metabolic diseases. Increased transcription efficiency was observed in -75A allele carriers compared to -75G allele homozygotes. +83C allele was associated with higher body mass index and waist-to-hip ratio in type II diabetes subjects. -75G/A and +83C/T polymorphisms were analyzed by RFLP-PCR in 334 individuals from a Brazilian elderly cohort. APOA1 polymorphisms were associated with age-related morbidities, as well as with triglycerides, total cholesterol, HDL, VLDL, LDL, creatinine, urea, albumin, glycated hemoglobin and fasting glucose serum levels. Allele frequencies were 0.102 and 0.21, respectively, for -75A and +83T. -75G allele showed significant association with hypertension (P = 0.001). An association between +83C allele and obesity was observed (P = 0.040) and this allele also showed an association with hypertension in the presence of cardiovascular disease (P = 0.047). Moreover, +83T allele was associated with lower glycated hemoglobin values (P = 0.026). To our knowledge, there is no data associating this polymorphism with glycated hemoglobin. Furthermore, individuals carrying AT haplotype have lower risk for developing hypertension (P = 0.0002), while GT haplotype carriers present decreased risk to develop obesity comparing to GC haplotype (P = 0.025). APOA1 polymorphisms analysis may be a useful tool to identify risk factors for subjects and families and clarify the physiopathological role of these polymorphisms in age-related diseases, such as hypertension and obesity.

    Background This is a prospective clinical study based on a large sample gathered from multiple centers in China,subordinating to 10th Five-Year Plan of National Science & Technology Progression. We analyzed the high-risk factors inducing hypertensive disorders in pregnancy (HDP) and estimated the potential effect of anti-oxidants administration,including vitamin C (VC), vitamin E (VE) and Salvia Miltiorrhiza L (SML), a Chinese herb medicine, in amelioration of the high-risk factors in pregnancy.Methods From April 2005 to July 2006, 4814 pregnant women from 24 national wide cooperative hospitals were involved in this prospective research. The participants were randomly divided into two groups: 1607 cases were in anti-oxidants group with administration of vitamins and SML; 3207 cases were in control group without any medicine given. Every participant was under monitoring for the morbidity of HDP and the high-risk factors were investigated in HDP cases in each group.Results (1)The morbidity of HDP was 3.55% in anti-oxidants group vs. 4.18% in control group. No statistical difference existed between the two groups (P>0.05). (2) In anti-oxidants group, the HDP morbidities among three subgroups: VC +VE + SML, VC + VE and SML only, were 5.51%, 3.05% and 5% respectively. It showed no statistical difference among three remedies (P>0.05). (3) The related index of factors affecting HDP showed in intensity sequence as follows: family HDP history > profession > education level > age > body weight. The incidence of HDP in normal population was 3.51%,and the incidence of HDP in high-risk pregnant women (family HDP history, heavy physical labor, low education level (middle school and below), age >40, body mass index ≥24) was 5.84%, which was obviously higher than that in normal population (P <0.01). In anti-oxidants group, the probability of HDP in women with high-risk factors was 3.81%, which was obviously lower than that in control group with high-risk factors at 7.14% (P<0

    Full Text Available Background: Hypertensive disorders are common complication occurring during pregnancy responsible for maternal & fetal mortality & morbidity. Though the condition is on decline, still stands a public health problem. Objectives: To determine risk factors of perinatal death in women with pregnancy induced hypertension. Materials & Method: A cross-sectional study was conducted over period of one year in the department of Obstetrics & Gynecology in NHL municipal college, Ahmadabad. A total of 100 pregnant women with PIH were enrolled in the study. A pre-tested structured Performa was prepared & women were interviewed to collect necessary information such as detailed history, clinical examination findings & investigations performed. Results were analyzed using MS Excel & Epi Info. Results: In the present study, 29%, 21% & 50 % were of mild PIH, moderate PIH & severe PIH respectively. The incidence of PIH was found more among teenage pregnancy, among primigravidas, those from low socio-economic status, those with history of PIH in previous pregnancy, having family history of PIH & those who were found obese. Emergency delivery, having diastolic blood pressure > 90 mm Hg, higher degree of proteinuria & low birth weight among PIH cases had an adverse perinatal outcome in terms of higher perinatal death. The findings were statistically significant On Univariate analysis; diastolic blood pressure & degree of proteinuria were found to be significant risk factors responsible for perinatal mortality among PIH women. Conclusion: Pregnancy induced hypertension is a common medical disorder associated with pregnancy. In the present study, PIH cases who delivered in emergency, with raised diastolic blood pressure & more proteinuria & neonate with low birth weight were found risk factors for perinatal death. Fetal morbidity & mortality can be reduced by early recognition & institutional management.

    Observational studies have shown an increased lifetime risk of cardiovascular disease (CVD) in women who experienced a hypertensive disorder in pregnancy. This risk is related to the severity of the pregnancy-related hypertensive disease and gestational age at onset. However, it has not been investigated whether these differences in CVD risk factors are already present at postpartum cardiovascular screening. We evaluated postpartum differences in CVD risk factors in 3 subgroups of patients with a history of hypertensive pregnancy. We compared the prevalence of common CVD risk factors postpartum among 448 women with previous early-onset preeclampsia, 76 women with previous late-onset preeclampsia, and 224 women with previous pregnancy-induced hypertension. Women with previous early-onset preeclampsia were compared with women with late-onset preeclampsia and pregnancy-induced hypertension and had significantly higher fasting blood glucose (5.29 versus 4.80 and 4.83 mmol/L), insulin (9.12 versus 6.31 and 6.7 uIU/L), triglycerides (1.32 versus 1.02 and 0.97 mmol/L), and total cholesterol (5.14 versus 4.73 and 4.73 mmol/L). Almost half of the early-onset preeclampsia women had developed hypertension, as opposed to 39% and 25% of women in the pregnancy-induced hypertension and late-onset preeclampsia groups, respectively. Our data show differences in the prevalence of common modifiable CVD risk factors postpartum and suggest that prevention strategies should be stratified according to severity and gestational age of onset for the hypertensive disorders of pregnancy.

    Background Hypertension is a common medical condition worldwide. It is an important public health challenge because of the associated morbidity, mortality, and the cost to the society. The objective of this study was to determine the prevalence of hypertension and its risk factors among attendants of adult outpatient departments at Jimma University Specialized Hospital in southwest Ethiopia. Materials and methods A hospital-based cross-sectional study was conducted on 734 participants aged 15 years or older from May 2012 to June 2012. A pretested structured questionnaire consisting of characteristics related to sociodemographic profiles and risk factors for hypertension was used for data collection. Three separate measurements of blood pressure and relevant anthropometric evaluation were taken according to current recommended standards. Chi-square test and other statistical analyses were done to employ appropriate interpretations of the findings. P-values of <0.05 were considered statistically significant. Results The mean age of the participants was 42.3 ± 13.2 years and 71.7% of them were 35 years and older; 58% of them were females. Overall prevalence of hypertension – defined by systolic blood pressure ≥140 and/or diastolic blood pressure ≥90 or reporting history of hypertension – was found to be 13.2%. Only 35.1% of them were aware of their hypertension and only 23.7% were on treatment. The overall control rate was 15.5%. Family history of hypertension, having diabetes mellitus, being overweight, and oral contraceptive use were associated with high blood pressure. Conclusion Hypertension was found to be prevalent; morbidity, awareness, treatment, and control in those with hypertension were low. Hence, intervention measures should be undertaken at the community level; particular emphasis should be placed on prevention by introducing lifestyle modifications and creating awareness about the problem so that early detection and intervention is possible

    Full Text Available OBJECTIVE: To study the associations between physically demanding work and occupational exposure to chemicals and hypertensive disorders during pregnancy within a large birth cohort study, the Generation R Study. METHODS: Associations between occupational characteristics and hypertensive disorders during pregnancy were studied in 4465 pregnant woman participating in a population-based prospective cohort study from early pregnancy onwards in the Netherlands (2002-2006. Mothers who filled out a questionnaire during mid-pregnancy (response 77% of enrolment, were included if they conducted paid employment, had a spontaneously conceived singleton live born pregnancy, and did not suffer from pre-existing hypertension (n = 4465. Questions on physical demanding work were obtained from the Dutch Musculoskeletal Questionnaire and concerned questions on manually handling loads of 25 kg or more, long periods of standing or walking, night shifts, and working hours. To assess occupational exposure to chemicals, job titles and task descriptions were linked to a job-exposure-matrix (JEM, an expert judgment on exposure to chemicals at the workplace. Information on hypertensive disorders during pregnancy was obtained from medical records. RESULTS: We observed no consistent associations between any of the work related risk factors, such as long periods of standing or walking, heavy lifting, night shifts, and working hours, nor exposure to chemicals with hypertensive disorders during pregnancy. CONCLUSION: This prospective birth cohort study suggests that there is no association of hypertensive disorders during pregnancy with physically demanding work or exposure to chemicals. However, the low prevalence of PIH and PE, combined with the low prevalence of occupational risk factors limit the power for inference and larger studies are needed to corroborate or refute these findings.

    Renin-angiotensin and kallikrein-kinin systems are interconnected, regulating blood pressure homeostasis. We have demonstrated the interactions among polymorphisms of the angiotensinogen (AGT) and endothelial nitric oxide synthase (NOS3) genes and conventional risk factors affecting the hypertension occurrence. Individuals were recruited (n=192) and classified into hypertensive (HG; n=140) and normotensive (NG; n=52) groups. The genotypic distribution of the Met235Thr (AGT) and Glu298Asp (NOS3) polymorphisms demonstrated that both are independent risk factors of hypertension (p=0.02 and p=0.008, respectively). The concomitant presence of these polymorphisms in the HG group was significantly different (p=0.001) from the NG. Both gene polymorphisms presented an additive effect for the unfavourable alleles T and A, respectively, and 95% of the double mutant homozygotes were classified into the HG. Specific interactions among certain conventional factors and the presence of at least one unfavourable allele presented significant odds towards hypertension. Blood pressure homeostasis was affected by genetic polymorphisms conditioned by the T and A alleles of the AGT and NOS3 genes, respectively, which acted independently. However, their interaction with smoking, sedentariness, age and total cholesterol may have increased the predisposition to hypertension, which may explain most of the hypertension cases.

    Abstract Fibroblast growth factor 23 (FGF-23) rises progressively in chronic kidney disease and is associated with adverse cardiovascular outcomes. FGF-23 putatively induces volume retention by upregulating the sodium-chloride cotransporter (NCC). We studied whether, conversely, interventions in volume status affect FGF-23 concentrations. We performed a post hoc analysis of 1) a prospective saline infusion study with 12 patients with arterial hypertension who received 2 L of isotonic saline over 4 hours, and 2) a randomized controlled trial with 45 diabetic nephropathy (DN) patients on background angiotensin-converting enzyme -inhibition (ACEi), who underwent 4 6-week treatment periods with add-on hydrochlorothiazide (HCT) or placebo, combined with regular sodium (RS) or low sodium (LS) diet in a cross-over design. Plasma C-terminal FGF-23 was measured by ELISA (Immutopics) after each treatment period in DN and before and after saline infusion in hypertensives. The patients with arterial hypertension were 45 ± 13 (mean ± SD) years old with an estimated glomerular filtration rate (eGFR) of 101 ± 18 mL/min/1.73 m2. Isotonic saline infusion did not affect FGF-23 (before infusion: 68 median [first to third quartile: 58–97] relative unit (RU)/mL, after infusion: 67 [57–77] RU/mL, P = 0.37). DN patients were 65 ± 9 years old. During ACEi + RS treatment, eGFR was 65 ± 25 mL/min/1.73 m2 and albuminuria 649 mg/d (230–2008 mg/d). FGF23 level was 94 (73–141) RU/mL during ACEi therapy. FGF-23 did not change significantly by add-on HCT (99 [74–148] RU/mL), LS diet (99 [75–135] RU/mL), or their combination (111 [81–160] RU/mL, P = 0.15). Acute and chronic changes in volume status did not materially change FGF-23 in hypertensive patients and DN, respectively. Our data do not support a direct feedback loop between volume status and FGF-23 in hypertension or DN. PMID:27861335

Methods. 121 persons have been investigated, 91 out — patients of both sexes, aged 33-55, with the diagnosis of arterial hypertension of stage II risk III, who have been taking Perindopril, Telmisartan and Bisoprolol for3 months. The control of arterial pressure level, biochemical analysis of metabolic indices and morning urine portion test for microalbuminuria has been carried out. Results. MAU has been revealed in 17,6% patients, occurring more frequently in men than in women. Microalbuminuria is accompanied by reliable decrease of total and ionized calcium and magnesium concentrations, an increase of potassium level in blood plasma, increase of cholesterol, triglycerides, glucose and levels. Patients with AH and renal dysfunction reliably demonstrate higher levels of systolic and diastolic arterial pressure in the morning and evening hours, their normalization effect after APs intake is significantly interconnected with MAU presence. Conclusion. In patients with AH and MAU the main risk factors of cardio-vascular diseases development are more expressed. Microalbuminuria is a risk factor in patients with arterial hypertension and may influence on the basic blood electrolyte balance. While carrying out antihypertensive therapy the presence of MAU should be taken into consideration

    Background Hypertension is associated with considerable morbidity and mortality. Improvement of its management to reduce adverse cardiovascular outcomes will require an understanding of the patient characteristics and treatment factors associated with uncontrolled blood pressure. Factors that affect blood pressure control have not been sufficiently described in Cameroon. The main goal of our study was to determine the predictors of blood pressure control in patients with hypertension in an urban city in Cameroon. Methods This was descriptive cross-sectional study from five outpatient hypertension consultation units in Hospitals in Yaoundé. Controlled hypertension was defined as blood pressure ≤140/90 mmHg. Logistic regression was used to determine factors associated with blood pressure control. Results Among the 440 patients enrolled in the survey, 280 (63.6%) were females. The mean age was 61 (SD ±11) years. Mean systolic blood pressure (SBP) was 147 mmHg and mean diastolic blood pressure (DBP) was 88 mmHg. Only 36.8% of patients had their mean blood pressure controlled (BP ≤140/90 mmHg). Multivariable logistic regression analysis revealed good adherence to anti-hypertensive medications (OR= 3.99; 95% CI: 2.20–7.23; Plifestyle changes (OR =1.5; 95% CI: 0.53–2.49; P=0.031) to be factors independently associated with controlled hypertension. Conclusions Only one out of three patients has their blood pressure controlled. The results of our study suggest that good adherence to treatment are important factors for tight blood pressure control in primary care. Further identification of patients at risk of non-adherence to treatment and poor blood pressure control can lead to targeted interventions to reduce hypertension related morbidity and mortality in this setting.

    Background Portacaval shunt (PCS) prevent hepatotrophic factors from flowing into the liver, but they enter directly the systemic circulation and worsen liver injury. This study was designed to investigate the effects of hepatotrophic factors through the portal vein on the liver in rats with portal hypertension after portacaval shunt.Methods Intrahepatic portal hypertension (IHPH) was induced by intragastric administration of carbon tetrachloride, and end-to-side PCS was performed. Eight normal rats served as controls, and eight rats with IHPH served as IHPH model (IHPH group). Another 32 rats with IHPH-PCS were randomly subdivided into 4 groups:normal saline (NS) given to 8 rats, hepatocyte growth factor (HGF) 8, insulin (INS) 8, hepatocyte growth factor and insulin (HGF+INS) 8. Hepatotrophic factors were infused into the portal vein through an intravenous catheter.Portal venous pressure (PVP) was measured. The levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were tested biochemically and those of hyaluronic acid (HA) and laminin (LN) were measured by radioimmunoassay. Hepatic fibrosis was assessed histologically and the expression of collagens type Ⅰ and Ⅲ were detected immunohistochemically. Ultrastructural change of hepatocytes and the number of mitochondria were observed under an electron microscope. The data were compared between groups and subgroups by Student-Newman-Keuls procedure with SPSS 10.0.Results PVP was significantly higher in the IHPH rats than in the control rats (P<0.05). The levels of serum ALT, AST, HA, and LN, hepatic fibrosis score, the amount of collagen deposition, collagens type Ⅰ and Ⅲ increased more significantly in the IHPH group than in the control rats (P<0.05).

    1. Pre-eclampsia is a human disease of pregnancy characterized by high blood pressure, proteinuria and end-organ damage, if severe. Pre-eclampsia is thought to be related to changes in early placental development, with the formation of a shallower than normal placental bed. 2. Transforming growth factor (TGF)-beta1 is a multifunctional fibrogenic growth factor involved in immune regulation that is elevated in some populations with a high risk of hypertensive end-organ disease related to increases in endothelin release. Transforming growth factor-beta1 is also an important factor in placental implantation. Alterations in TGF-beta1 may be related to abnormal placental development in early pregnancy and, thus, are a candidate for the development of hypertension in pre-eclampsia. 3. The aim of the present study was to examine the placental distribution and serum concentration of TGF-beta1 in patients with pre-eclampsia compared with normal pregnancy. 4. Patients with pre-eclampsia (n = 12) were compared with patients with normal pregnancy (n = 14). Transforming growth factor-beta1 was determined by TGF-beta1 Max ELISA (Promega, Madsion, WI, USA) after serum dilution (1/150) and acid activation. Placental distribution was determined by immunostaining with TGF-beta1 (Santa Cruz, Santa Cruz, CA, USA; 20 ng/mL) and the villi and decidual trophoblast were scored for intensity and extent of staining. 5. Patients with pre-eclampsia had a mean gestational age of 36 weeks, whereas those with a normal pregnancy had a mean gestational age of 39.0 +/- 0.4 weeks. There was no difference in TGF-beta1 concentration between the two groups (mean (+/-SEM) 27.1 +/- 1.0 vs 26.4 +/- 0.7 pg/mL for normal pregnancy and pre-eclampsia, respectively; P = 0.73, Mann-Whitney U-test). There was no correlation between systolic or diastolic blood pressure and TGF-beta1 concentration (regression analysis P = 0.4 and 0.2). Immunostaining was absent in the villous trophoblast cells and endovascular and

    Health-related quality of life (HRQOL) is poorly understood in patients with chronic kidney disease (CKD) prior to end-stage renal disease. The association between psychosocial measures and HRQOL has not been fully explored in CKD, especially in African Americans. We performed a cross-sectional analysis of HRQOL and its association with sociodemographic and psychosocial factors in African Americans with hypertensive CKD. There were 639 participants in the African American Study of Kidney Disease and Hypertension Cohort Study. The Short Form-36 was used to measure HRQOL. The Diener Satisfaction with Life Scale measured life satisfaction, the Beck Depression Inventory-II assessed depression, the Coping Skills Inventory-Short Form measured coping, and the Interpersonal Support Evaluation List-16 was used to measure social support. Mean participant age was 60 years at enrollment, and 61% were male. Forty-two percent reported a household income below $15,000/year. Higher levels of social support, coping skills, and life satisfaction were associated with higher HRQOL, while unemployment and depression were associated with lower HRQOL (p<0.05). There was a significant positive association between higher estimated glomerular filtration rate (eGFR) with the Physical Health Composite (PHC) score (p=0.004) but not the Mental Health Composite (MHC) score (p=0.24). Unemployment was associated with lower HRQOL, and lower eGFR was associated with lower PHC. African Americans with hypertensive CKD with better social support and coping skills had higher HRQOL. This study demonstrates an association between CKD and low HRQOL and highlights the need for longitudinal studies to further examine this association. PMID:22153804

    Few reports have examined tissue factor (TF) and forkhead box transcription factor O-1 (FoxO1) expression in chronic thromboembolic pulmonary hypertension (CTEPH) animal models. To investigate the role of TF and FoxO1 and their interactions during CTEPH pathogenesis in a rat model. Autologous blood clots were repeatedly injected into the pulmonary arteries through right jugular vein to induce a rat model of CTEPH. Hemodynamic parameters, histopathology, and TF and FoxO1expression levels were detected. The mean pulmonary arterial pressure (mPAP), pulmonary vascular resistance and vessel wall area/total area (WA/TA) ratio in the experiment group increased significantly than sham group (P model of CTEPH can be successfully established by the injection of autologous blood clots into the pulmonary artery. TF and FoxO1 may play a key role in vascular remodeling during CTEPH pathogenesis.

    To delineate the constitutive pulmonary vascular phenotype of the TβRIIΔk-fib mouse model of scleroderma, and to selectively induce pulmonary endothelial cell injury using vascular endothelial growth factor (VEGF) inhibition to develop a model with features characteristic of pulmonary arterial hypertension (PAH). The TβRIIΔk-fib mouse strain expresses a kinase-deficient transforming growth factor β (TGFβ) receptor type II driven by a fibroblast-specific promoter, leading to ligand-dependent up-regulation of TGFβ signaling, and replicates key fibrotic features of scleroderma. Structural, biochemical, and functional assessments of pulmonary vessels, including in vivo hemodynamic studies, were performed before and following VEGF inhibition, which induced pulmonary endothelial cell apoptosis. These assessments included biochemical analysis of the TGFβ and VEGF signaling axes in tissue sections and explanted smooth muscle cells. In the TβRIIΔk-fib mouse strain, a constitutive pulmonary vasculopathy with medial thickening, a perivascular proliferating chronic inflammatory cell infiltrate, and mildly elevated pulmonary artery pressure resembled the well-described chronic hypoxia model of pulmonary hypertension. Following administration of SU5416, the pulmonary vascular phenotype was more florid, with pulmonary arteriolar luminal obliteration by apoptosis-resistant proliferating endothelial cells. These changes resulted in right ventricular hypertrophy, confirming hemodynamically significant PAH. Altered expression of TGFβ and VEGF ligand and receptor was consistent with a scleroderma phenotype. In this study, we replicated key features of systemic sclerosis-related PAH in a mouse model. Our results suggest that pulmonary endothelial cell injury in a genetically susceptible mouse strain triggers this complication and support the underlying role of functional interplay between TGFβ and VEGF, which provides insight into the pathogenesis of this disease.

    The present study aimed to evaluate the hypertension status of community residents, analyze environmental and epigenetic factors, and propose prevention measures for hypertension. In our study, different methylation levels were distinguished utilizing melting temperature (Tm) values in both the case and the control group. Multiple logistic regression analysis was used to estimate the risk of having essential hypertension (EH) between hypertensive and nonhypertensive participants. A receiver-operating characteristic curve was used to analyze Tm cutoff levels of methylation. The average DNA Tm was 71.784 with a standard deviation of 0.210. The Tm value of community residents (Fujian, China) was inversely correlated with systolic and diastolic blood pressure. Student t test analysis showed a clear separation in Tm expression levels between the hypertensive and the control group (p < 0.05). The Tm value was lower in the hypertension group than in the normotensive group. Multivariate regression analysis showed that high levels of DNA methylation were a protective factor in hypertension with adjustment of demographic and environmental factors, whereas when the Tm value increased by 0.1 units, the risk of hypertension was reduced by 0.652 times. Patients that smoked and consumed an irregular diet demonstrated a lower degree of methylation in the presence of hypertension. DNA methylation affects the risk for the development of hypertension; therefore, epigenetic markers could be used to measure hypertension levels to help elucidate the pathogenesis of EH. © 2017 S.

    Background The mechanisms responsible for the pathogeneses of gestational hypertension and preeclampsia are unclear. Tumor necrosis factor-α (TNF-α) is a pro-inflammatory Th1-type cytokine. TNFA gene is located in the human leukocyte antigen (HLA) class III region of the major histocompatibility complex (MHC) on chromosome 6. The high TNF-α mRNA expression may be associated with the TNF2 (A) allele, which is the polymorphism of TNF-α at position -308 in promoter region. This study assessed whether the TNF2 (A) allele at position -308 plays a role in the alteration of blood pressure (BP) and urinary protein excretion during pregnancy.Methods The original prospective cohort study comprised 1623 pregnant women from January 2000 to October 2001. The G/A polymorphism was done by restriction fragment length polymorphism (RFLP) analysis with Nco I enzyme.Results The distributions of the G/A polymorphism of TNF-α in the promoter region at position -308 were wild-type 72.4% and variant 27.6%, respectively. The frequency of TNF2 (A) allele was approximately 0.15 for Caucasian pregnant women in the study. It was not significantly different in the distributions of genotypes and G/A allele frequencies among the three groups of pregnant women with gestational hypertension, preexisting hypertension and normal blood pressure (P>0.05). The maternal blood pressure in the third trimester was significantly higher in the group of women possessing the TNF2 (A) allele compared to homozygous for the TNF1 (G) allele (systolic BP, P<0.01 and diastolic BP, P<0.05). The elevated blood pressure in the TNF2 (A)group was accompanied by higher urinary protein excretion in the third trimester (P<0.05). The blood pressure and urinary protein excretion did not change apparently between the two groups in the first and second trimesters (P>0.05).Conclusions Maternal TNF2 (A) allele of TNF-α promoter region at position -308 could play a role in the alteration of blood pressures and

    Resistant hypertension is defined as blood pressure that remains above 140/90 mmHg in spite of the continuous use of three antihypertensive agents in optimal dose, including diuretic, and lifestyle changes. According to data from United States of America and Europe, the prevalence ranges from 10 up to 30% in patients with hypertension. Numerous biological and lifestyle factors can contribute to the development of resistant hypertension: medications, volume overload, obesity, diabetes mellitus, older age, renal parenchymal and renovascular disease, primary aldosteronism, obstructive sleep apnea, pheochormocytoma, Cushing’s syndrome, thyroid diseases, aortic coarctation. For diagnosing patient’s history is important, assessing compliance, regular blood pressure measurement, physical examination, biochemical evaluation and noninvasive imaging. The evaluation including 24h ambulatory monitoring of blood pressure (ABPM) in the identification of “non-dipper” hypertension. Non-dipper has particular importance and the prevalence of abnormally high sleep blood pressure is very often in chronic kidney patients. Therapeutic restoration of normal physiologic blood pressure reduction during night-time sleep (circadial variation) is the most significant independent predictor of decreased risk and the basis for the chronotherapy. The resistant hypertension treatment is achieved with nonpharmacological and pharmacological approach, treating secondary hypertension causes and invasive procedures. PMID:26005390

    Hypertension is a very prevalent risk factor for cardiovascular disease. The prevalence of resistant hypertension, i.e., uncontrolled hypertension with 3 or more antihypertensive agents including 1 diuretic, is between 5% and 30% in the hypertensive population. The causes of resistant hypertension are multifactorial and include behavioral and biological factors, such as nonadherence to pharmacological treatment. All current treatment guidelines highlight the positive role of physical exercise as a non-pharmacological tool in the treatment of hypertension. This paper draws attention to the possible role of physical exercise as an adjunct non-pharmacological tool in the management of resistant hypertension. A few studies have investigated it, employing different methodologies, and taken together they have shown promising results. In summary, the available evidence suggests that aerobic physical exercise could be a valuable addition to the optimal pharmacological treatment of patients with resistant hypertension.

    Full Text Available Objective: to determine the frequency of exposure to four cardiovascular risk factors in patients from a hypertension control program. This program belongs to a second level hospital located in Risaralda, Colombia. Methodology: a total of 133 patients from a hypertension control program were assessed. The Martin-Bayarre-Grau test (MBG test, the body mass index, and the blood pressure measurements were used as instruments for measuring adherence to treatment. Results: 80% of the patients were female. The average systolic and diastolic arterial pressure values were 141 and 86 mm Hg respectively. 74% of the patients exhibited overweight and obesity, and only 42.1% of the patients showed complete adherence to the antihypertensive therapy. Additionally, 100% of the patients had at least one of the assessed cardiovascular risks. Conclusions: high frequency of exposure to cardiovascular risks is an indicator of the lack of treatment adherence. An interdisciplinary team is needed to ensure that patients understand their disease and to develop strategies to improve adherence

    Full Text Available Background and Objective. Cardiovascular diseases are primary causes of death worldwide with well documented risk factors whose varying impacts added to the complexity in CVD management dictate the need for region-specific studies. We aimed at investigating the interactions between CVD risk factors and hypertension in Ngaoundéré. Methods. A cross-sectional survey was carried out from March to August 2014. Sociodemographic, fasting blood glucose, blood pressure, and anthropometric data were recorded. Statistical analyses were carried out using SAS software version 9.1. Results. 700 adults resident in Ngaoundéré for at least two years consented and were included in the survey. Abdominal obesity, physical inactivity, and hypertension were the dominant risk factors recording 51.1%, 35.4%, and 20.4%, respectively. The prevalence of hyperglycaemia, tobacco consumption, obesity, and alcohol consumption was 5.6%, 8.3%, 9.6%, and 18.1%, respectively. Advanced age, hyperglycaemia, a divorced marital status, and alcohol consumption were independent determinants of high blood pressure. Conclusion. Physical inactivity, abdominal obesity, and hypertension were the most prevalent CVD risk factors, and the role of advanced age and hyperglycaemia in the occurrence of high blood pressure was reiterated. Health programs need to focus on effective screening, prevention, and control of CVDs in the Adamawa Region and Cameroon at large.

    The use of blood pressure measurements have become a routine part of physical exam for the evacuation of cardiovascular health adults and, more recently, children. The most widely used definition of hypertension is delineate as greater than 90 % BP according to age, sex, and height by the National High Blood Pressure Education Program. Current research suggests that pediatric hypertension is influenced by multitude of factors including birth weight, maturity during birth, heredity, and diet leading to primary hypertension. Factors influencing secondary hypertension include renal abnormalities, coarctation of the aorta, medications, neoplasm, etc. The treatment for pediatric hypertension is carried out with diet and exercise as the first line of defense. Only under non-compliance with diet and exercise is pharmaceutical intervention appropriate. This paper outlines a concise summary of the current understanding and research for scientists, clinicians, as well as for the general population to better understand pediatric hypertension.

    Diana Zabini

    Full Text Available Chronic thromboembolic pulmonary hypertension (CTEPH is a rare disease with persistent thrombotic occlusion or stenosis of the large pulmonary arteries resulting in pulmonary hypertension. Surgical removal of the neointimal layer of these vessels together with the non-resolved thrombus consisting of organized collagen-rich fibrotic areas with partly recanalized regions is the treatment of choice (pulmonary endarterectomy, PEA. The present study investigates endothelial cells isolated from such material as well as factors present in the surgical PEA material, which may contribute to impairment of recanalization and thrombus non-resolution. We observed muscularized vessels and non-muscularized vessels in the PEA material. The isolated endothelial cells from the PEA material showed significantly different calcium homeostasis as compared to pulmonary artery endothelial cells (hPAECs from normal controls. In the supernatant (ELISA as well as on the tissue level (histochemical staining of the PEA material, platelet factor 4 (PF4, collagen type I and interferon-gamma-inducible 10 kD protein (IP-10 were detected. CXCR3, the receptor for PF4 and IP-10, was particularly elevated in the distal parts of the PEA material as compared to human control lung (RT-PCR. PF4, collagen type I and IP-10 caused significant changes in calcium homeostasis and affected the cell proliferation, migration and vessel formation in hPAECs. The presence of angiostatic factors like PF4, collagen type I and IP-10, as recovered from the surgical PEA material from CTEPH patients, may lead to changes in calcium homeostasis and endothelial dysfunction.

    To analyze incident hypertension and its risk factors based on 11.9 years follow-up of a recent National Examination Survey cohort in Germany. Out of 7124 participants of the German National Health Interview and Examination Survey 1998 (GNHIES98), 640 had died at follow-up 2008-2011 and 3045 were reexamined as part of the German Health Interview and Examination Survey for Adults 2008-2011 (DEGS1). Baseline and follow-up included standardized blood pressure (BP) measurements. Hypertension was defined as BP of at least 140/90 mmHg or intake of antihypertensive medication in participants with known hypertension. Out of 2231 GNHIES98-DEGS1 participants aged 18-79 years without hypertension in 1998, 26.2% developed hypertension within a mean of 11.9 (range 10.0-14.1) years (men 29.0%, women 23.4%). In univariate analysis, hypertension incidence was positively associated with age, BMI, initial BP levels, pulse pressure, and alcohol consumption. Comorbidities such as diabetes and hyperlipidemia increased the chance to develop hypertension. In the multivariate model, initial SBP and DBP levels had the strongest influence on the development of future hypertension (7% increase in men and 5% in women per mmHg SBP). The percentage of aware, treated, and controlled hypertensive patients were 75.8, 62.1, and 50.3% in men and 83.8, 73.3, and 59.0% in women. The high 11.9-year incidence in all age groups points to the lifelong potential for prevention of hypertension.

    Hypertension, one of the major treatable cardiovascular (CV) risk factors, usually occurs in association with other major risk factors. As well as providing rapid blood pressure (BP) goal attainment, antihypertensive therapy should also provide reductions in CV events and mortality in a wide range of patients. For this, higher dosages and combinations of antihypertensive agents are often required. ACE inhibitors are recommended as first-line agents for control of hypertension in patients with additional CV risk factors. The PEACH (Perindopril's Effect At Controlling Hypertension) study was a community-based study performed to evaluate the effectiveness and safety of high-dose perindopril in patients with mild-to-moderate hypertension and additional risk factors for CV disease. This was an open-label, multicentre observational study conducted in Canadian general practice clinics. The study assessed the efficacy and tolerability of perindopril given once daily for 10 weeks uptitrated to the maximal recommended dose of perindopril as required for BP control in newly diagnosed or previously treated patients with uncontrolled mild to moderate hypertension and >or=1 additional risk factor. Patients not achieving target BP after 2 weeks of therapy were uptitrated from perindopril 4 mg to perindopril 8 mg once daily. Efficacy endpoints included reduction in systolic (SBP) and diastolic (DBP) BP and BP control. Tolerability assessments included adverse effects and physicians' assessment of tolerability. The number of missed doses was also recorded. Overall, 2220 patients with hypertension and >or=1 other risk factor were prescribed perindopril at 291 centres; 51.9% were male, 78.3% Caucasian, 12.8% Asian, 36.2%>or=65 years of age and 34.5% had uncontrolled BP despite previous antihypertensive treatment. Compared with previously treated patients, treatment-naive patients had fewer risk factors, and a higher proportion were Asian (prisk factors. Perindopril produced

    Full Text Available Esayas Kebede Gudina,1 Yadani Michael,1 Sahilu Assegid2 1Department of Internal Medicine, Jimma University, Jimma, Ethiopia; 2Department of Epidemiology, Jimma University, Jimma, Ethiopia Background: Hypertension is a common medical condition worldwide. It is an important public health challenge because of the associated morbidity, mortality, and the cost to the society. The objective of this study was to determine the prevalence of hypertension and its risk factors among attendants of adult outpatient departments at Jimma University Specialized Hospital in southwest Ethiopia. Materials and methods: A hospital-based cross-sectional study was conducted on 734 participants aged 15 years or older from May 2012 to June 2012. A pretested structured questionnaire consisting of characteristics related to sociodemographic profiles and risk factors for hypertension was used for data collection. Three separate measurements of blood pressure and relevant anthropometric evaluation were taken according to current recommended standards. Chi-square test and other statistical analyses were done to employ appropriate interpretations of the findings. P-values of <0.05 were considered statistically significant. Results: The mean age of the participants was 42.3 ± 13.2 years and 71.7% of them were 35 years and older; 58% of them were females. Overall prevalence of hypertension – defined by systolic blood pressure ≥140 and/or diastolic blood pressure ≥90 or reporting history of hypertension – was found to be 13.2%. Only 35.1% of them were aware of their hypertension and only 23.7% were on treatment. The overall control rate was 15.5%. Family history of hypertension, having diabetes mellitus, being overweight, and oral contraceptive use were associated with high blood pressure. Conclusion: Hypertension was found to be prevalent; morbidity, awareness, treatment, and control in those with hypertension were low. Hence, intervention measures should be undertaken

    This prospective, randomized, open-label multicenter trial evaluated the efficacy of catheter-based renal denervation (Symplicity, Medtronic) versus intensified pharmacological treatment including spironolactone (if tolerated) in patients with true-resistant hypertension. This was confirmed by 24-hour ambulatory blood pressure monitoring after excluding secondary hypertension and confirmation of adherence to therapy by measurement of plasma antihypertensive drug levels before enrollment. One-hundred six patients were randomized to renal denervation (n=52), or intensified pharmacological treatment (n=54) with baseline systolic blood pressure of 159±17 and 155±17 mm Hg and average number of drugs 5.1 and 5.4, respectively. A significant reduction in 24-hour average systolic blood pressure after 6 months (-8.6 [95% cofidence interval: -11.8, -5.3] mm Hg; P<0.001 in renal denervation versus -8.1 [95% cofidence interval: -12.7, -3.4] mm Hg; P=0.001 in pharmacological group) was observed, which was comparable in both groups. Similarly, a significant reduction in systolic office blood pressure (-12.4 [95% cofidence interval: -17.0, -7.8] mm Hg; P<0.001 in renal denervation versus -14.3 [95% cofidence interval: -19.7, -8.9] mm Hg; P<0.001 in pharmacological group) was present. Between-group differences in change were not significant. The average number of antihypertensive drugs used after 6 months was significantly higher in the pharmacological group (+0.3 drugs; P<0.001). A significant increase in serum creatinine and a parallel decrease of creatinine clearance were observed in the pharmacological group; between-group difference were borderline significant. The 6-month results of this study confirmed the safety of renal denervation. In conclusion, renal denervation achieved reduction of blood pressure comparable with intensified pharmacotherapy.

    This article examined the association between dietary patterns and cardiovascular risk factors in Chinese older adults. For this study, older adults with one or more cardiovascular risk factors or a history of cardiovascular disease were randomly selected using health check medical records from the Changshu and Beijing Fangshan Centers for Disease Control and Prevention. Exploratory factor analysis and cluster analysis was used to extract dietary pattern factors. Log binomial regression analysis was used to analyse the association between dietary patterns and chronic disease related risk factors. Four factors were found through factor analysis. A high level of internal consistency was obtained, with a high Cronbach's alpha coefficient of 0.83. Cluster analysis identified three dietary patterns: healthy diet, Western diet, and balanced diet. Findings in this sample of Chinese adults correspond to those reported in previous studies, indicating that a Western diet is significantly related to likelihood of having obesity, hypertension and the metabolic syndrome. The identification of distinct dietary patterns among Chinese older adults and the nutritional status of people with chronic diseases suggest that the three dietary patterns have a reasonable level of discriminant validity. This study provides evidence that a FFQ is a valid and reliable tool to assess the dietary patterns of individuals with chronic diseases in small- to medium-size urban and rural settings in China. It also validates the significant association between dietary pattern and cardiovascular disease risk factors, including body mass index, blood pressure, triglycerides, and metabolic conditions. Clinical diagnosis of chronic disease further confirmed this relationship in Chinese older adults.

    2014-03-19

    In a recent issue of Critical Care, Cheng and colleagues conducted a rabbit model study that demonstrated that intra-abdominal hypertension (IAH) may damage both gut anatomy and function. With only 6 hours of IAH at 25 mmHg, these authors observed an 80% reduction in mucosal blood flow, an exponential increase in mucosal permeability, and erosion and necrosis of the jejunal villi. Such dramatic findings should remind all caring for the critically ill that IAH may severely damage the normal gut barrier functions and thus may be reasonably expected to facilitate bacterial and mediator translocation. The potential contribution of IAH as a confounding factor in the efficacy of selective decontamination of the digestive tract should be considered.

    Full Text Available The objective of this study was to investigate the self-care behaviors among hypertensive patients in primary care. A cross-sectional survey, with 318 hypertensive patients, was conducted in a rural area in Beijing, China, in 2012. Participants were mainly recruited from a community health clinic and completed questionnaires assessing their self-care behaviors, including data on adherence to a prescribed medication regimen, low-salt diet intake, smoking habits, alcohol consumption, blood pressure monitoring, and physical exercise. The logistic regression model was used for the analysis of any association between self-care behaviors and age, gender, duration of hypertension, self-rated health, marital status, education level, diabetes status, or body mass index. Subjects that adhered to their medication schedule were more likely to have hypertension for a long duration (OR, 3.44; 95% CI 1.99–5.97. Older participants (OR, 1.80; 95% CI 1.08–2.99 were more likely to monitor their blood pressure. Subjects who did not partake in physical exercise were more likely to be men, although the difference between genders was not significant (OR, 0.60; 95% CI 0.36–1.01. Patients with shorter history of hypertension, younger and being males have lower self-care behaviors. Primary care providers and public health practitioner should pay more attention to patients recently diagnosed with hypertension as well as younger male patients.

All residents (n = 1,742 of Bambuí, Minas Gerais State, Brazil (15,000 inhabitants aged superscript three 60 years were selected, and 1494 (85.8% were interviewed and examined. Of these, 919 (61.5% were hypertensive, 704 were aware of their condition (study population, and 578 were under treatment. Only 38.8% of the individuals under treatment presented controlled systolic and diastolic pressures (< 140 and < 90mmHg, respectively. Independent associations with treatment of hypertension were found for, in decreasing order of magnitude: less time elapsed since the last blood pressure measurement, greater number of physician visits in the past 12 months, higher body mass index, female gender, history of coronary disease, changes in diet due to arterial hypertension, and higher family income. Our results show that the factors most strongly associated with treatment of hypertension (use of health services could be modified through adequate health policies for older adults.

    Full Text Available Abstract:In large populations, individuals born in France have significantly different levels of blood pressure (BP and cardiovascular (CV risk factors than African and Asian populations born in their own country but living in France. Our objective was to investigate the impact of country of birth on BP and CV risk factors in a subpopulation selected on the basis of hypertension, either alone or associated with type 2 diabetes. In the individuals with hypertension alone, brachial systolic, diastolic, mean and pulse pressure (PP, heart rate, augmentation index and PP amplification were significantly higher in African-born than French- and Asian-born populations. In the individuals with hypertension and diabetes both, only augmentation index, PP amplification and brachial and central PP, but not brachial systolic, diastolic, mean BP and heart rate, were elevated when the African-born subgroup was compared to the French- and Asian-born populations. Increased body mass index and deprivation scores were consistently associated with the African-born population. The combination of diabetes and hypertension in African populations was associated with increased aortic stiffness and PP and greater body weight. In individuals with systolic hypertension, increased PP requires systolic BP to be reduced whereas notable reductions in diastolic BP may have deleterious consequences.

    Full Text Available The main purpose of the present study was to assess the role of motivation in the effective cognitive activity of elderly hypertension (HTN patients provided with antihypertensive treatment; 25 patients with HTN took part in the study, stage 1-2; their mean age was 67.6±6.1. The psychological examination program embraced a quantitative measurement of intelligence quotient (IQ with the Wechsler Adult Intelligence Scale, and an investigation into the qualitative features of their cognitive processes, applying a pathopsychological study procedure (Zeigarnik, 1962, 1972 and the principles of psychological syndrome analysis (Vygotsky-Luria-Zeigarnik school. The results showed that within the psychological syndrome structure of cognitive disorders in HTN patients, the leading part is played by two syndrome-generating factors: a neurodynamic factor and a motivational factor. The patients with reduced motivation would achieve poor general test results, if compared with the group of highly motivated participants. A correlation analysis of the data revealed the interconnection between frequency disturbances in motivation and the frequency in occurrence of various signs of cognitive decline, such as low efficiency in memorization and delayed recall, as well as lower IQ test results. The data provide a strong argument to support the hypothesis that motivation is of particular importance as a factor in the generation of cognitive disorders in HTN patients.

    Full Text Available Abstract Hyperlipidemia is a major risk factor in etiology of cardiovascular disease. Previous studies have shown association between vegetarian diet and low total serum cholesterol as well as LDL-cholesterol which is a pointer to low risk of cardiovascular disease. Dietary fiber, antioxidants and other classes of nutrients have been reported to ameliorate cardiovascular risk factors. Fruits and vegetables being rich sources of fiber and antioxidants have been the focus in intervention studies. The current work reports the effect local fruits and vegetables on cardiovascular risk factors in African hypertensive subjects in an 8 week study. Though there was no significant difference in the Body Mass Index and HDL-cholesterol at the end of the eighth week, there were significant reductions (P -1; total serum cholesterol (226.60 ± 6.15 to 179.20 ± 5.78 and LDL-cholesterol (135.69 ± 5.56 to 93.07 ± 7.18 mgdL-1. We concluded that consumption of combination of local fruits and vegetables may reduce the incidence of cardiovascular risk factors in Africans.

    The frequency of hypertension and obesity is gradually growing in Hungary. At present 68.5% of men and 78% of women are obese. Hypertension and obesity are the most important risk factors of morbidity and mortality from cardiovascular disease. The relationship between increased sympathetic activity and hypertension is well known. Waist circumference and body fat mass correlate significantly with sympathetic activity, in which hyperlipidemia plays also a role. The increased activity of renin-angiotensin-aldosterone system via its vascular and renal effects also contributes to an increase of blood pressure. Increased sympathetic activity with decreasing vagal tone accompanying the imbalance of the autonomous nervous system is independent and significant risk factor of cardiovascular events including sudden cardiac death.

    Cardiovascular diseases and related risk factors suppose a challenge to public health due to the mortality and health costs involved. This study has aimed to assess the blood pressure control in a population cohort and to identify the factors associated with poor control. A cardiovascular health examination was carried out in a random sample of 4013 individuals aged 15 years and above who were living in Castilla y Leon in 2004. The study included the medical history, physical exam and blood tests. A new health study was performed in 2009, including 2954 people from the initial sample, 1306 of whom were patients with hypertension. Strict blood pressure control was defined as <140/90 mm Hg. Bivariate analysis was performed and odds ratio was calculated by a regression logistic model. Blood pressure levels were above the established levels in 55.9%, without differences between men and women. The regression model showed that diabetes, obesity, smoking habit and previous systolic blood pressure values, with odds ratio of 3.87, 1.58, 1.49 and 1.13 per 5 mm Hg, respectively, are independently associated with uncontrolled blood pressure. Age did not show statistical significance. More than half of the patients with hypertension are not well controlled. This study provides information about the characteristics of the patients with poor control of hypertension in Castilla y León, which will allow policy makers to develop new primary and secondary prevention activities.

Materials and Methods: A total of 803, randomly selected students aged 17 to 23 years (346 male, 457 female from different colleges in Kuwait, were included in the study between 2009 and 2010. Systolic and diastolic blood pressure measurements were taken by trained personnel. Pre-hypertension was defined as systolic pressure between 120 and 139 mm Hg or diastolic pressure between 80 and 89 mm Hg. Risk factor measurements that were determined, included smoking, body mass index (BMI, and family history of hypertension. Blood samples were collected and impaired glucose tolerance (IGT and lipid profile levels were determined. Results: There were no hypotensive students. Normotensives constituted 53.5% (n = 430, pre-hypertensives formed 39.5% (n = 317, and hypertensive students comprised of 7% (n = 56. The overall proportions of hypertension and pre-hypertension were higher among male students (85.7 and 64.4% than female students (14.3 and 35.6%, respectively. Hypertensive and pre-hypertensive students versus normotensive students had significantly higher levels of BMI-based obesity, smoking, glycated hemoglobin (HbA1c, and IGT. Also, hypertensive and pre-hypertensive, compared to normotensive students, had significantly higher proportions (21.4, 18.3, and 4.0%, respectively of risky high-density lipoprotein (HDL level (< 1 mg / dL, cholesterol (7.1, 3.8, and 1.4%, respectively, and triglycerides (TG (17.9, 9.1, and 7.9%, respectively where p was< 0.001, 0.016, and 0.051, respectively. Conclusion: Hypertensive and pre-hypertensive students showed elevated levels of lipids and BMI-based obesity more than normotensive students. TG, HDL, HbA1c, and cholesterol appeared to influence pre-hypertension.

    This study is a continuation of (Report I) identification of the occupational risk of arterial hypertension (AH) in 13 occupational groups (3842 workers, men). In previous work there was eliminated the influence of traditional factors of the cardiovascular risk, in this study there was implemented the identification of the components of a healthy worker effect (HWE) and the elimination of their influence on the occupational risks of hypertension. Identification and removal of components HWE--the effect of a healthy recruitment (EHR) and the effect of the healthy worker persisting to work (EHWPW--was carried out by the analytic rearranging of the standardized for age and obesity prevalence rate of arterial hypertension with the use of own methodological approaches. For the determination of the presence and severity of EHR there was performed an analysis of the initial prevalence rate of arterial hypertension in the youngest age groups (under 31 years). To overcome HER standardized for age and obesity indices of the arterial hypertension prevalence rate were adjusted by the ratio of the frequency of arterial hypertension in the most young occupational and reference comparable groups. Identification of HWPW was executed by comparing the frequency of AH among workers retiring within 3 years from the occupational groups when compared to the whole sample. Then on the additional risk value there was adjusted the overall prevalence rate of AH in the occupation profession to overcome EHWPW. As a result of the consistent correction and elimination of the influence of HWE components on the prevalence rate of AH, there were obtained risks values, primarily reflecting the impact of occupational factors which can be considered as true occupational risks. Factors of the cardiovascular risk and HWE significantly modified true occupational risks for AH in a number of occupational groups up to inversion. At the same time, the pronouncement of EHR has a paramount importance in the

    To determine which specific groups of occupational stress factors influence the duration of temporary work disability related to arterial hypertension and joint complications/co-morbidities. Workers (n = 1398; 1009 in the exposed group, 389 in the control group) with arterial hypertension who worked at one workplace for a minimum of 10 years were divided into 10 subgroups, depending on the presence of joint complications/co-morbidities. The intensity of seven groups of occupational stress factors, the total score of Occupational Stress Index (OSI) and the average number of lost working days during 1 year were analysed. The number of lost working days due to arterial hypertension and joint complications/co-morbidities was significantly higher in the exposed group. In all subgroups of the exposed group there was a high correlation between the number of lost working days and the total OSI score. Specific occupational stress factors were associated with specific complications: High Demands with chronic myocardial infarction, Strictness with cerebral haemorrhage, Conflict/Uncertainty with cerebral infarction, Extrinsic Time Pressure with acute myocardial infarction, and Avoidance/Symbolic Aversiveness with non-insulin-dependent diabetes. There are specific groups of occupational stress factors which can influence the duration of work disability associated with certain complications and co-morbidities of arterial hypertension.

    Tinnitus is considered a multi-factorial symptom. Arterial hypertension has been cited as a tinnitus etiological factor. To assess the scientific evidence on the associations between arterial hypertension and tinnitus. A systematic review was performed using PubMed, ISI Web, Lilacs and SciELO scientific databases. This review included articles published in Portuguese, Spanish, French and English correlating tinnitus with hypertension. Letters to editors and case reports were excluded. A total of 424 articles were identified, of which only 20 met the inclusion criteria. Studies that analyzed the incidence of hypertension in tinnitus patients tended to show an association, while those that evaluated the incidence of tinnitus in hypertensive patients did not. There is evidence of an association between tinnitus and hypertension, although a cause and effect relationship is uncertain. Changes in the cochlear microcirculation, resulting in hearing loss, may be an adjuvant factor in tinnitus pathophysiology.

    To establish the prevalence of microalbuminuria in a group of patients with systemic arterial hypertension (SAH) to analyze the association between this parameter and cardiovascular risk factors as well as with SAH treatment. This is a sub-analysis of 564 patients of Mexico, extracted from an international, observational, and cross-sectional study followed by specialists, The study included patients with SAH without any other causes of microalbuminuria. Microalbuminuria in these patients had a prevalence of 63.8% (95% IC 58.4, 69,3) and correlated with a wide variety of risk factors and concomitant cardiovascular diseases Most patients with microalbuminuria already received treatment with angiotensin II receptor antagonists (50%), without pretending to establish the impact of the drugs on the microalbuminuria values. The prevalence of patients with SAH and high cardiovascular risk is high in this study and justifies their management and care with multifactorial strategies aimed to adequately control their blood pressure and to modify other current cardiovascular risk factors.

    Personality is an important epidemiological factor for understanding health outcomes. This study investigated the associations of trait procrastination with hypertension and cardiovascular disease (HT/CVD) and maladaptive coping by testing an extension of the procrastination-health model among individuals with and without HT/CVD. Individuals with self-reported HT/CVD (N = 182) and healthy controls (N = 564), from a community sample, completed an online survey including measures of personality, coping, and health outcomes. Logistic regression analysis controlling for demographic and higher order personality factors found that older age, lower education level and higher procrastination scores were associated with HT/CVD. Moderated mediation analyses with bootstrapping revealed that procrastination was more strongly associated with maladaptive coping behaviours in participants with HT/CVD than the healthy controls, and the indirect effects on stress through maladaptive coping were larger for the HT/CVD sample. Results suggest procrastination is a vulnerability factor for poor adjustment to and management of HT/CVD.

Aims: To evaluate factors affecting the efficacy of telmisartan in daily clinical practice. Setting and Design: Prospective practice-based 12-week uncontrolled cohort study. Materials and Methods: Consecutive incident/prevalent outpatients with mild to moderate essential hypertension were started on telmisartan 40 mg/day with optional up-titration to 80 mg/day in order to achieve seated systolic (SSBP and diastolic (SDBP blood pressure < 140/90 mm Hg. Intent-to-treat (ITT, N=282 and per protocol (PP, N=275 efficacy assessment was based on SSBP/SDBP reduction and delivered doses. Results: SSBP/SDBP decreased (165.2±13.1 / 98.3±6.7 mm Hg to 137.9±13.2 / 82.6±7.3 mm Hg, whilst telmisartan was up-titrated in 40.5% of patients during the study. Multivariate (practically identical ITT and PP analysis indicated poorer response in obese vs. non-obese patients: lesser SDBP reduction (by around 2.2-2.3 mm Hg, P < 0.05 with higher odds of dose up-titration (odds ratio, OR around 1.90, P < 0.05; and better response in: a patients started on telmisartan monotherapy than when added to a preexisting treatment: greater SSBP/SDBP reduction (by around 4.0 and 3.0 mm Hg, respectively, P < 0.05 with comparable odds of up-titration; b diabetics vs. non-diabetics: greater SDBP reduction (by around 3.6-3.7 mm Hg, P < 0.05 with comparable odds of up-titration; c men vs. women: slightly greater SDBP reduction (by around 1.2 mm Hg, 0.05 P < 0.1 with lower odds of up-titration (OR around 0.51, P < 0.05. Conclusion: Previous unsuccessful treatment, obesity, diabetes and gender should be considered in order to optimize the use of telmisartan for mild to moderate essential hypertension in daily clinical practice.

    Hypertension (HT) is the common adverse event associated with vascular endothelial growth factor receptor-tyrosine kinase inhibitors (VEGFR-TKI). The present study was performed to identify the predictive factors of TKI-induced HT and to determine the classes of antihypertensive agents (AHTA) that demonstrate optimal efficacy against this type of HT. The charts of 50 cases of patients that had received VEGFR-TKI treatment were retrospectively examined. The association between patient background and TKI-induced HT, and the effect of administering AHTA were analyzed. High systolic blood pressure at baseline was identified to be a predictive factor for HT. In addition, there was no difference observed between calcium channel blockers (CCBs) and angiotensin receptor II blockers (ARBs) as first-line AHTA for the control of HT. The findings of the present study may aid with predicting the onset of TKI-induced HT, as well as for its management via the primary use of either CCBs or ARBs. PMID:24959266

    The aim of this study was to investigate the expression of hepatocyte growth factor(HGF)and Fas in placentas of uncomplicated pregnant women and those with hypertensive disorder complicating pregnancy(HDCP),and elucidate the possible relationship between HGF and apoptosis of trophoblasts.Reverse transcription-polymerase chain reaction(RT-PCR)was undertaken to examine the concentration of HGF mRNA and Fas mRNA obtained from 34 cases of HDCP and 30 cases of uncomplicated pregnancy.The expression of HGF mRNA in mild preeclampsia,severe preeclampsia and eclampsia cases was significantly lower than that in the uncomplicated cases(0.43±0.12,0.38±0.09,0.19±0.17 versus 0.67±0.19,P<0.05),while the expression of Fas mRNA in mild preeclampsia,severe preeclampsia and eclampisa cases was significantly higher than that in the uncomplicated cases(1.58±0.26,2.96±0.14,5.98±1.17versus 1.01±0.36,P<0.05).For HGF mRNA and Fas mRNA,there was no difference between gestational hypertension cases and control cases.Decreased HGF mRNA or increased Fas mRNA was found along with the progress of HDCP.Negative correlation was found between the expressions of HGF and Fas.These results indicate that HGF inhibits the apoptosis mediated by Fas,and the reduced expression of HGF in HDCP may be responsible for the apoptosis of trophoblasts.

    Background Tumor necrosis factor-induced protein 3 (TNFAIP3) gene has been shown important in cardiac remodeling. The aim of the present study was to investigate whether the variants of TNFAIP3 gene are associated with left ventricular hypertrophy (LVH) in hypertensive patients.Methods Four representatives of all the other single nucleotide polymorphisms (SNPs) in TNFAIP3 gene were tested for association with hypertrophy in two independent hypertensive populations (n=2120 and n=324).Results We found that only the tag SNP (rs5029939) was consistently lower in the hypertensives with cardiac hypertrophy than in those without cardiac hypertrophy in the two study populations, indicating a protective effect on LVH (odds ratio (OR) (95% confidence interval (CI))0.58 (0.358-0.863), P=0.035; OR (95% CI)=0.477 (0.225-0.815), P<0.05,respectively). Multiple regression analyses confirmed that the patients with G allele of rs5029939 had less thickness in inter-ventricular septum, left ventricular posterior wall, relative wall thickness and left ventricular mass index than did those with CC allele in the hypertensive patients in both study populations (all P<0.01).Conclusion These findings indicate that the SNP (rs5029939) in the TNFAIP3 gene may serve as a novel protective genetic marker for the development of LVH in patients with hypertension.

Approximately 40%–60% of patients with HT do not follow the prescribed treatment. The aim of the study was to analyze the relationship between selected variables and adherence to hypotensive pharmacological treatment. Besides socioclinical variables, the study focused on the role of illness acceptance.Participants and methods: The study included 602 patients with HT. Adherence and acceptance of illness were assessed using the following validated instruments: the Acceptance of Illness Scale (AIS and the Morisky Medication Adherence Scale (MMAS.Results: The high-adherence group comprised a significantly higher percentage of patients with high illness acceptance scale scores than that of patients with low-to-moderate scores (42.4 vs 31.8%; P=0.008<0.01. The odds ratio (OR showed that high adherence to pharmacological treatment was >1.5 times as likely to occur in the high acceptance group as in the low-to-moderate acceptance group (OR =1.58, 95% CI 1.14–2.19.

PE is now considered as a cardiovascular disease risk factor and a number of studies have shown that experiencing PE increases the prevalence of various cardiovascular risk factors, such as metabolic syndrome and HT. In this study, we aimed to investigate any possible relationship between the ABO/Rh blood group system and PE in Turkey. In the second part of the study, we examined the relationship between the ABO blood group system and development of HT after PE. Patients and methods: A total of 250 patients with PE from Kayseri Training and Research Hospital between 2002 and 2012 were included in the study. Patients were classified according to blood groups (A, B, AB, and O and Rh status (+/-. Results: There was a significant difference between the patients with PE and the control group in terms of distribution of ABO blood groups and the percentage of group AB was found to be higher in patients with PE compared to the control group (P=0.029. The risk of developing PE was significantly higher in group AB than other blood groups (P=0.006. The risk of developing HT after PE was significantly higher in group O than other blood groups (P=0.004. Discussion: In this study, we found that the patients with blood group AB have a higher risk for PE. The patients with PE of blood group O are at high risk of developing HT, and Rh factor was identified as another risk at this point and these patients should be closely followed postpartum.

    Background Chronic respiratory disease-associated pulmonary hypertension (PH) is an important subtype of PH, which lacks clinical epidemiological data in China. Methods Six hundred and ninety three patients hospitalized from 2010 to 2013 were classified by echocardiography according to pulmonary arterial systolic pressure (PASP): mild (36≤ PASP 20 mm) were associated with moderate-to-severe PH, while RV [odds ratio (OR) =3.53, 95% CI, 2.17–5.74], NT-proBNP (OR=2.44, 95% CI, 1.51–3.95), HCT (OR=1.03, 95% CI, 1.00–1.07) and PaCO2 (OR=1.01, 95% CI, 1.00–1.03) were independent risk factors. Conclusions PH related to respiratory diseases is mostly mild to moderate, and the severity is associated with the category of respiratory disease. Increased HCT can be an independent risk factor for PH related to chronic respiratory diseases. PMID:27076929

The concept of renin inhibition for managing hypertension by blocking the RAAS pathway at its point of activation is very attractive since the renin-angiotensinogen reaction is the first and rate-limiting step in the generation of angiotensin II (Ang II. Aliskiren, the first in a new class of orally effective direct renin inhibitors (DRIs, is approved for the treatment of hypertension. It is effective in reducing BP in the general population of hypertensive patients and in special patient groups such as obese persons, and has a tolerability and safety profile similar to placebo. Aliskiren has renoprotective, cardioprotective and anti-atherosclerotic effects in animal models that appear to be independent of BP lowering. It reduces proteinuria in diabetic patients and has favorable neurohumoral effects in patients with symptomatic heart failure. Additional outcome trials are needed to establish the role of this novel class of antihypertensive medication in the therapeutic armamentarium.Keywords: hypertension, renin inhibitors, renin-angiotensin-aldosterone system

Methods Each participating practice identified a random sample of 150-300 adults aged ≥ 18 years diagnosed with hypertension. The primary outcome variable was BP control (BP Results Overall, 6,527 hypertensive patients were identified for study inclusion. More than half (54.3% were female, and mean age was 64.7 years. Almost half (48.7% were obese (BMI ≥ 30 kg/m2. About 1 in every 4 patients (25.3% had diabetes, and 60.7% had dyslipidemia. Mean blood pressure was 132.5/77.9 mmHg, and 55.0% of all patients had controlled BP; 62.4% of non-diabetic patients, and 33.3% of diabetic hypertensive patients, had BP controlled to recommended levels. Most (81.7% hypertensive patients had ≥ 1 cardiometabolic risk factor, and 12.2% had all 3 risk factors. As compared to hypertensive patients without additional risk factors, adjusted odds ratios for BP control were significantly lower for all combinations of CMRFCs (ORs 0.15-0.83, all p Conclusions Across 28 US practices, only 18% of hypertensive patients did not have any additional cardiometabolic risk factors. The high prevalence of CMRFCs presents a challenge to effective hypertension management.

    Hypertension in pregnancy is a risk factor for future hypertension and cardiovascular disease. This may reflect an underlying familial predisposition or persistent damage caused by the hypertensive pregnancy. We sought to isolate the effect of hypertension in pregnancy by comparing the risk of hypertension and cardiovascular disease in women who had hypertension in pregnancy and their sisters who did not using the dataset from the Genetic Epidemiology Network of Arteriopathy study, which examined the genetics of hypertension in white, black, and Hispanic siblings. This analysis included all sibships with at least one parous woman and at least one other sibling. After gathering demographic and pregnancy data, BP and serum analytes were measured. Disease-free survival was examined using Kaplan-Meier curves and Cox proportional hazards regression. Compared with their sisters who did not have hypertension in pregnancy, women who had hypertension in pregnancy were more likely to develop new onset hypertension later in life, after adjusting for body mass index and diabetes (hazard ratio 1.75, 95% confidence interval 1.27-2.42). A sibling history of hypertension in pregnancy was also associated with an increased risk of hypertension in brothers and unaffected sisters, whereas an increased risk of cardiovascular events was observed in brothers only. These results suggest familial factors contribute to the increased risk of future hypertension in women who had hypertension in pregnancy. Further studies are needed to clarify the potential role of nonfamilial factors. Furthermore, a sibling history of hypertension in pregnancy may be a novel familial risk factor for future hypertension.

    The hippocampus of spontaneously hypertensive rats (SHR) and deoxycorticosterone (DOCA)-salt hypertensive rats shows decreased cell proliferation and astrogliosis as well as a reduced number of hilar cells. These defects are corrected after administration of 17β-oestradiol (E(2) ) for 2 weeks. The present work investigated whether E(2) treatment of SHR and of hypertensive DOCA-salt male rats modulated the expression of brain-derived neurotrophic factor (BDNF), a neurotrophin involved in hippocampal neurogenesis. The neurogenic response to E(2) was simultaneously determined by counting the number of doublecortin-immunopositive immature neurones in the subgranular zone of the dentate gyrus. Both hypertensive models showed decreased expression of BDNF mRNA in the granular zone of the dentate gyrus, without changes in CA1 or CA3 pyramidal cell layers, decreased BDNF protein levels in whole hippocampal tissue, low density of doublecortin (DCX)-positive immature neurones in the subgranule zone and decreased length of DCX+ neurites in the dentate gyrus. After s.c. implantation of a single E(2) pellet for 2 weeks, BDNF mRNA in the dentate gyrus, BDNF protein in whole hippocampus, DCX immunopositive cells and the length of DCX+ neurites were significantly raised in both SHR and DOCA-salt-treated rats. These results indicate that: (i) low BDNF expression and deficient neurogenesis distinguished the hippocampus of SHR and DOCA-salt hypertensive rats and (ii) E(2) was able to normalise these biologically important functions in the hippocampus of hypertensive animals.

    Full Text Available Abstract Background Hypertensive disease in pregnancy remains the leading cause of maternal mortality in the Netherlands. Seventeen percent of the clinical pregnancies are complicated by hypertension and 2% by preeclampsia. The Dutch Society of Obstetrics and Gynaecology (NVOG has developed evidence-based guidelines on the management of hypertension in pregnancy and chronic hypertension. Previous studies showed a low adherence rate to other NVOG guidelines and a large variation in usual care in the different hospitals. An explanation is that the NVOG has no general strategy of practical implementation and evaluation of its guidelines. The development of an effective and cost effective implementation strategy to improve adherence to the guidelines on hypertension in pregnancy is needed. Methods/Design The objective of this study is to assess the cost effectiveness of an innovative implementation strategy of the NVOG guidelines on hypertension including a computerised decision support system (BOS compared to a common strategy of professional audit and feedback. A cluster randomised controlled trial with an economic evaluation alongside will be performed. Both pregnant women who develop severe hypertension or pre-eclampsia and professionals involved in the care for these women will participate. The main outcome measures are a combined rate of major maternal complications and process indicators extracted from the guidelines. A total of 472 patients will be included in both groups. For analysis, descriptive as well as regression techniques will be used. A cost effectiveness and cost utility analysis will be performed according to the intention-to-treat principle and from a societal perspective. Cost effectiveness ratios will be calculated using bootstrapping techniques.

    The majority of cardiovascular disease (CVD) is caused by risk factors that can be controlled, treated or modified. In terms of attributable deaths, the leading cardiovascular disease risk factor is hypertension. The Australian Health Survey results showed some startling figures-4.6 million adult Australians are hypertensive (>140/90 mmHg). Further, a fifth of the adult population experience hypertension, with more than two out of three not attaining blood pressure target levels. This is despite an estimated cost of $1 billion per annum spent on managing hypertension. It is now well recognised that the level of risk for coronary heart disease is linked to an individual's risk profile. Results indicate that many Australians have multiple risk factors, including hypertension. It could be considered that these numbers provide a proxy indicator of secondary prevention failure. Considerable attention needs to be given to the assessment of the combined risk of those with hypertension enabling effective management of identified, modifiable risk factors. We look forward to presenting the absolute risk profiles when the Australian Health Survey biometric results are released.

    This study was conducted to determine factors that promote success in an introductory college computer science course and to determine what, if any, differences appear between genders on those factors. The model included math background, attribution for success/failure, self-efficacy, encouragement, comfort level in the course, work style preference, previous programming experience, previous non-programming computer experience, and gender as possible predictive factors for success in the computer science course. Subjects included 105 students enrolled in an introductory computer science course. The study revealed three predictive factors in the following order of importance: comfort level (with a positive influence), math background (with a positive influence), and attribution to luck (with a negative influence). No significant gender differences were found in these three factors. The study also revealed that both a formal class in programming (which had a positive correlation) and game playing (which had a negative correlation) were predictive of success. The study revealed a significant gender difference in game playing with males reporting more experience with playing games on the computer than females reported.

    This study has been designed to evaluate the impact of adiponectin levels on left ventricular geometry and function in visceral obesity-associated hypertension. 94 consecutive subjects, 53 of them were hypertensives and 41 normotensives with age ≤ 65 years, subgrouped according to the presence or absence of visceral obesity, were studied. Total adiponectin levels were measured by a validated competitive radioimmunoassay. Left ventricular telediastolic internal diameter, interventricular septum, posterior wall thickness, total left ventricular mass (LVM) and normalized for height to the 2.7 power (LVM/h(2.7)), relative wall thickness, left ventricular ejection fraction by echocardiography and isovolumic relaxation time, E/A ratio and deceleration time of E velocity, by pulsed-wave Doppler, were calculated. Plasma adiponectin levels were significantly lower in visceral obesity-associated hypertensives than lean hypertensives (p hypertensive groups, and in visceral obesity-associated normotensives in comparison with lean normotensives. Adiponectin levels correlated inversely with LVM/h(2.7) but only in normotensives (adjusted R squared 0.77, p hypertensives (0.67, p obesity. Multiple regression analysis indicated that adiponectin levels remain significantly associated (p obesity-associated normotensive and hypertensive subjects. In this last group, adiponectin, more than blood pressure, may be able to explain the development of cardiac damage.

    Transcription factor E26 transformation-specific sequence-1 (ETS-1) is a transcription factor that regulates the expression of a variety of genes, including growth factors, chemokines, and adhesion molecules. We recently demonstrated that angiotensin II increases the glomerular expression of ETS-1 and that blockade of ETS-1 ameliorates the profibrotic and proinflammatory effects of angiotensin II. The Dahl salt-sensitive rat is a paradigm of salt-sensitive hypertension associated with local activation of the renin-angiotensin system. In these studies, we determined whether: (1) salt-sensitive hypertension is associated with renal expression of ETS-1 and (2) ETS-1 participates in the development of end-organ injury in salt-sensitive hypertension. Dahl salt-sensitive rats were fed a normal-salt diet (0.5% NaCl diet) or a high-salt diet (4% NaCl) for 4 weeks. Separate groups on high-salt diet received an ETS-1 dominant-negative peptide (10 mg/kg/d), an inactive ETS-1 mutant peptide (10 mg/kg/d), the angiotensin II type 1 receptor blocker candesartan (10 mg/kg/d), or the combination high-salt diet/dominant-negative peptide/angiotensin II type 1 receptor blocker for 4 weeks. High-salt diet rats had a significant increase in the glomerular expression of the phosphorylated ETS-1 that was prevented by angiotensin II type 1 receptor blocker. ETS-1 blockade reduced proteinuria, glomerular injury score, fibronectin expression, urinary transforming growth factor-β excretion, and macrophage infiltration. Angiotensin II type 1 receptor blocker reduced proteinuria, glomerular injury score, and macrophage infiltration, whereas concomitant ETS-1 blockade and angiotensin II type 1 receptor blocker had additive effects and reduced interstitial fibrosis. Our studies demonstrated that salt-sensitive hypertension results in increased glomerular expression of phosphorylated ETS-1 and suggested that ETS-1 plays an important role in the pathogenesis of end-organ injury in salt

    Portal hypertension, one of the vascular diseases, not only has lesions in liver, but also changes in vascular structures and functions of extrahepatic portal system, systemic system and pulmonary circulation. The pathological changes of vasculopathy in portal hypertension include remodeling of arterialized visceral veins, intimal injury of visceral veins and destruction of contractile structure in visceral arterial wall. The mechanisms of vasculopathy in portal hypertension may be attributed to the changes of hemodynamics in portal system, immune response, gene modulation, vasoactive substances, and intrahepatic blood flow resistance. Portal hypertension can cause visceral hyperdynamic circulation, and the development and progression of visceral vasculopathy,while visceral vasculopathy can promote the development and progression of portal hypertension and visceral hyperdynamic circulation in turn. The aforementioned three factors interact in the pathogenesis of hepatic cirrhosisinduced portal hypertension and are involved in hemorrhage due to varicose vein rupture.

    Full Text Available BACKGROUND Perioperative hypertension is a situation whose management is suggested by the clinical judgement much more than clinical evidences. JNC 7 guidelines give a classification of blood pressure (BP, without any mention specifically dedicated to patients undergoing surgery. The ACC/AHA guidelines recommend deferring surgery if diastolic BP is above 110 mmHg and systolic BP is above 180 mmHg. AIM OF THE STUDY In this review we considered pathogenetic, clinical and therapeutic factors related to perioperative management of hypertensive patients. DISCUSSION In actual trend of the preoperative evaluation, alone hypertension is considered as a minor risk factor. BP values ≤ 180/110 mmHg do not influence the outcomes in patients who underwent noncardiac surgery. Therefore, in these conditions it’s not necessary to delay surgery. Hypertensive picks are possible during the operation, mostly because of the intubation, but, much more dangerous, falls of pressure are possible. The intraoperative arterial pressure should be maintained within 20% of the best estimated preoperative arterial pressure, especially in patients with markedly elevated preoperative pressures. After surgery the arterial BP can increase for stress factors, pain, hypoxia and hypercapnia, hypothermia and infusional liquids overload. For all these reasons a careful monitoring is mandatory. Anti-hypertensive medication should be continued during the postoperative period in patients with known and treated hypertension, as unplanned withdrawal of treatment can result in rebounded hypertension. The decision to give anti-hypertensive drugs must be made for each patient, taking into account their normal BP and their postoperative BP. With regard to the optimal treatment of the patient with poorly or uncontrolled hypertension in the perioperative evaluation, recent guidelines suggest that the best treatment may consider cardioselective β-blockers therapy, but also clonidin by

    Characteristics of hotel housekeeping work increase the risk for hypertension development. Little is known about the influences of such work on hypertension management. For this qualitative study, 27 Haitian immigrant hotel housekeepers from Miami-Dade County, FL were interviewed. Interview transcripts were analyzed with the assistance of the Atlas.ti software for code and theme identification. Influences of hotel housekeeping work on hypertension management arose both at the individual and system levels. Factors at the individual level included co-worker dynamics and maintenance of transmigrant life. Factors at the system level included supervisory support, workload, work pace, and work hiring practices. No positive influences were reported for workload and hiring practices. Workplace interventions may be beneficial for effective hypertension management among hotel housekeepers. These work influences must be considered when determining effective methods for hypertension management among hotel housekeepers. © 2013 Wiley Periodicals, Inc.

    Background Characteristics of hotel housekeeping work increase the risk for hypertension development. Little is known about the influences of such work on hypertension management. Methods For this qualitative study, 27 Haitian immigrant hotel housekeepers from Miami-Dade County, FL were interviewed. Interview transcripts were analyzed with the assistance of the Atlas. ti software for code and theme identification. Results Influences of hotel housekeeping work on hypertension management arose both at the individual and system levels. Factors at the individual level included co-worker dynamics and maintenance of transmigrant life. Factors at the system level included supervisory support, workload, work pace, and work hiring practices. No positive influences were reported for workload and hiring practices. Conclusions Workplace interventions may be beneficial for effective hypertension management among hotel housekeepers. These work influences must be considered when determining effective methods for hypertension management among hotel housekeepers. PMID:23775918

    Background Glaucoma is mainly characterized by the loss of retinal ganglion cells. Ciliary neurotrophic factor (CNTF) is believed to stimulate the regeneration of axons of retinal ganglion cells. The objective of our study was to detect the expression of CNTF in the retina of a rat glaucoma model with increased intraocular pressure (lOP).Methods The rat glaucoma model was set up by electrocoagulating at least three episcleral and limbal veins. The location and the expression level of CNTF were detected at 1, 3, 7, 14, and 28 days post-surgery by immunohistochemistry, semiquantitative reverse-transcription polymerase chain reaction (RT-PCR), and Western blot analysis.Results The rat glaucoma model with chronic, moderately elevated lOP was successfully produced. A minimum expression of CNTF was found in the ganglion cell layer of the retinas of the control group, and temporally increased expression and intensity of CNTF were found in the experimental retinas.Conclusion The expression of endogenous CNTF in the rat retina was found altered after the induction of ocular hypertension.

    To assess adherence of Palestinian hypertensive patients to therapy and to investigate the effect of a range of demographic and psychosocial variables on medication adherence. A questionnaire-based, cross-sectional descriptive study was undertaken at a group of outpatient clinics of the Ministry of Health, in addition to a group of private clinics and pharmacies in the West Bank. Social and demographic variables and self-reported drug adherence (Morisky scale) were determined for each patient. Low adherence with medications was present in 244 (54.2%) of the patients. The multivariate logistic regression showed that younger age (risk of poor adherence who should be targeted for interventions to achieve better blood pressure control and hence prevent complications. This study should encourage the health policy makers in Palestine to implement strategies to reduce non-compliance, and thus contribute toward reducing national health care expenditures. Better patient education and communication with healthcare professionals could improve some factors that decrease adherence such as forgetfulness and dissatisfaction with treatment.

    Full Text Available ObjectiveTo investigate the possible risk factors for rebleeding after splenectomy and pericardial devascularization in the treatment of portal hypertension due to liver cirrhosis, and to provide a certain basis for reducing the incidence of digestive tract re-hemorrhage for these patients. MethodsA retrospective analysis was performed on 238 cirrhotic patients with portal hypertension who underwent splenectomy and pericardial devascularization in the First Hospital of Lanzhou University from December 2003 to December 2013. These patients were divided into postoperative rebleeding group (n=32 and non-bleeding group (n=206. Univariate analysis (t test or chi-square test and multivariate logistic regression analysis were performed to investigate the risk factors for rebleeding after splenectomy and pericardial devascularization. ResultsOf the 32 patients with postoperative rebleeding, 17 had esophagogastric variceal bleeding, 11 had bleeding due to portal hypertensive gastropathy, and 4 had stress ulcer bleeding. The univariate analysis showed that there were significant differences between the two groups in the following factors: Child-Pugh classification of liver function, degree of liver cirrhosis evaluated intraoperatively, pathological changes of the gastric mucosa, platelet count, prothrombin time (PT, activated partial thromboplastin time (APTT, and presence of diabetes (all P<0.05. The multivariate logistic regression analysis suggested that the significant independent influential factors for postoperative rebleeding were presence of diabetes, Child-Pugh classification of liver function, degree of liver cirrhosis evaluated intraoperatively, diffuse lesion of the gastric mucosa, PT, and APTT. ConclusionFor cirrhotic patients with portal hypertension, the appropriate methods for managing these risk factors are of great clinical significance for preventing rebleeding after splenectomy and pericardial devascularization.

    Low-sodium Dietary Approaches to Stop Hypertension (DASH) diets are base producing but restrict red meat without clear justification. We hypothesized that a vitality diet (VD), a low-sodium DASH-type diet with a low dietary acid load containing 6 servings of 100 g cooked lean red meat per week, would be more effective in reducing blood pressure (BP) compared with a higher acid load reference healthy diet (RHD) based on general dietary guidelines to reduce fat intake and increase intake of breads and cereals. A randomized, parallel dietary intervention study was conducted to compare the BP-lowering effect of these 2 diets in postmenopausal women with high/normal BP. Women were randomly assigned to follow either VD or RHD for 14 weeks. Home BP was measured daily with an automated BP monitor under standard conditions. Of 111 women commencing the study, 95 completed (46 VD, 49 RHD). Systolic BP (SBP) throughout the intervention was lower in the VD group compared to the RHD group (repeated-measures analysis of variance time by diet, P = .04), such that at the end of the study, the VD had a fall of SBP by 5.6 +/- 1.3 mm Hg (mean +/- SEM) compared with a fall of 2.7 +/- 1.0 mm Hg in the RHD (group difference, P = .08). When only those taking antihypertensive medications were assessed, the VD (n = 17) had a significant fall of 6.5 +/- 2.5 mm Hg SBP (P = .02) and 4.6 +/- 1.4 mm Hg diastolic BP (P = .005) after 14 weeks, and their BP was lower than that of the RHD group (n = 18) throughout the study (P dietary acid load, which also included lean red meat on most days of the week, was effective in reducing BP in older women, particularly in those taking antihypertensive medications.

    Pre-hypertension is a major risk factor for hypertension. African Americans (blacks) have more prevalent and severe hypertension than whites, but it is unknown whether progression from pre-hypertension is accelerated in blacks. We examined this question in a prospective cohort study of 18,865 non-hypertensive persons (5,733 [30.4% black, 13,132 [69.6%]) white) 18–85 years old. Electronic health record data were obtained from 197 community-based outpatient clinics in the Southeast U.S. Days elapsing from study entry to hypertension diagnosis, mainly blood pressure [BP] ≥140 systolic and/or ≥90 mmHg diastolic on two consecutive visits established conversion time within a maximum observation period of 2550 days. Cox regression modeling was used to examine conversion to hypertension as a function of race, while controlling for age, sex, baseline systolic and diastolic BP, body mass index [BMI], diabetes mellitus and chronic kidney disease. The covariable adjusted median conversion time when 50% became hypertensive was 365 days earlier for blacks than whites (626 vs 991 days, phypertension. Additional predictors included age 35–54 years, diastolic BP 80–89 mmHg, overweight and obesity, and diabetes mellitus (all phypertension to hypertension is accelerated in blacks, which suggests that effective interventions in pre-hypertension could reduce racial disparities in prevalent hypertension.

    The development of pulmonary hypertension (PH) involves the uncontrolled proliferation of pulmonary smooth muscle cells via increased growth factor receptor signaling. However, the role of epidermal growth factor receptor (EGFR) signaling is controversial, as humans with advanced PH exhibit no changes in EGFR protein levels and purpose of the present study was to determine whether there are post-translational mechanisms that enhance EGFR signaling in PH. The EGFR inhibitor, gefinitib, significantly attenuated EGFR signaling and prevented the development of PH in monocrotaline (MCT)-exposed rats, confirming the contribution of EGFR activation in MCT induced PH. There was an early MCT-mediated increase in hydrogen peroxide, which correlated with the binding of the active metabolite of MCT, monocrotaline pyrrole, to catalase Cys377, disrupting its multimeric structure. This early oxidative stress was responsible for the oxidation of EGFR and the formation of sodium dodecyl sulfate (SDS) stable EGFR dimers through dityrosine cross-linking. These cross-linked dimers exhibited increased EGFR autophosphorylation and signaling. The activation of EGFR signaling did not correlate with pp60(src) dependent Y845 phosphorylation or EGFR ligand expression. Importantly, the analysis of patients with advanced PH revealed the same enhancement of EGFR autophosphorylation and covalent dimer formation in pulmonary arteries, while total EGFR protein levels were unchanged. As in the MCT exposed rat model, the activation of EGFR in human samples was independent of pp60(src) phosphorylation site and ligand expression. This study provides a novel molecular mechanism of oxidative stress stimulated covalent EGFR dimerization via tyrosine dimerization that contributes into development of PH.

    Silent myocardial ischemia (SMI) is frequently observed in patients with essential hypertension (EH). The major risk factor for SMI is uncontrolled blood pressure (BP), but SMI is also observed in patients with well-controlled BP. To evaluate the prevalence of SMI and the factors associated with SMI in EH patients with well-controlled BP. The medical records of 859 EH patients who underwent simultaneous 24-h ambulatory blood pressure monitoring (ABPM) and 24-h ambulatory electrocardiogram recording (AECG) were retrospectively evaluated. Each SMI episode was characterized by: (a) ST segment depression ≥0.5 mm; (b) duration of ST segment depression >60 s; and (c) reversibility of the ST segment depression. Overall 126 EH patients (14.7 %) had at least one episode of SMI. The SMI events were more frequent among patients with poorly controlled compared to those with well-controlled BP [86/479 (17.95 %) vs. 40/380 (10.52 %), p < 0.01]. Among EH patients with well-controlled BP, current and past smoking as well as the presence of an additional metabolic syndrome (MetS) constitutive element (obesity, impaired fasting glucose level or dyslipidemia) were significantly associated with the occurrence of SMI. In all EH patients with well-controlled BP and AECG evidence of SMI, there were one or more coronary artery stenotic lesions greater than 50 % found at coronary angiography. In EH patients who are current smokers, or have one or more additional components of a MetS there is markedly reduced benefit associated with good BP control with regard to the occurrence of myocardial ischemia: in this patient category, an AECG may help detect this condition.

    130 breast cancer patients were retrospectively evaluated for side-effects to estimate the influence of arterial hypertension. All were treated with mastecomy and irradiation (telecobalt). 79 patients had normal blood pressure, 51 showed arterial hypertension. Hypertension proved to be the strongest endogeneous factor for the development of side-effects. In contrast to the patients with normal blood pressure those with hypertension showed significant more arm lymphedema (p < 0.005) and teleangiectasia (p < 0.0001). Other endogeneous factors, like cardiovascular diseases or obesity, taken together led only to a higher rate of subcutaneous fibrosis (p < 0.002). Patients with arterial hypertension should receive axillary radiation only for strict indications and perhaps with a reduced dosage. (orig./MG).

  9. KCNA5 gene is not confirmed as a systemic sclerosis-related pulmonary arterial hypertension genetic susceptibility factor

    Science.gov (United States)

    2012-01-01

    Introduction Potassium voltage-gated channel shaker-related subfamily member 5 (KCNA5) is implicated in vascular tone regulation, and its inhibition during hypoxia produces pulmonary vasoconstriction. Recently, a protective association of the KCNA5 locus with systemic sclerosis (SSc) patients with pulmonary arterial hypertension (PAH) was reported. Hence, the aim of this study was to replicate these findings in an independent multicenter Caucasian SSc cohort. Methods The 2,343 SSc cases (179 PAH positive, confirmed by right-heart catheterization) and 2,690 matched healthy controls from five European countries were included in this study. Rs10744676 single-nucleotide polymorphism (SNP) was genotyped by using a TaqMan SNP genotyping assay. Results Individual population analyses of the selected KCNA5 genetic variant did not show significant association with SSc or any of the defined subsets (for example, limited cutaneous SSc, diffuse cutaneous SSc, anti-centromere autoantibody positive and anti-topoisomerase autoantibody positive). Furthermore, pooled analyses revealed no significant evidence of association with the disease or any of the subsets, not even the PAH-positive group. The comparison of PAH-positive patients with PAH-negative patients showed no significant differences among patients. Conclusions Our data do not support an important role of KCNA5 as an SSc-susceptibility factor or as a PAH-development genetic marker for SSc patients. PMID:23270786

    To determine the proportion of pre-hypertension and hypertension in college students in Kuwait and their related risk factors. A total of 803, randomly selected students aged 17 to 23 years (346 male, 457 female) from different colleges in Kuwait, were included in the study between 2009 and 2010. Systolic and diastolic blood pressure measurements were taken by trained personnel. Pre-hypertension was defined as systolic pressure between 120 and 139 mm Hg or diastolic pressure between 80 and 89 mm Hg. Risk factor measurements that were determined, included smoking, body mass index (BMI), and family history of hypertension. Blood samples were collected and impaired glucose tolerance (IGT) and lipid profile levels were determined. There were no hypotensive students. Normotensives constituted 53.5% (n = 430), pre-hypertensives formed 39.5% (n = 317), and hypertensive students comprised of 7% (n = 56). The overall proportions of hypertension and pre-hypertension were higher among male students (85.7 and 64.4%) than female students (14.3 and 35.6%), respectively. Hypertensive and pre-hypertensive students versus normotensive students had significantly higher levels of BMI-based obesity, smoking, glycated hemoglobin (HbA1c), and IGT. Also, hypertensive and pre-hypertensive, compared to normotensive students, had significantly higher proportions (21.4, 18.3, and 4.0%, respectively) of risky high-density lipoprotein (HDL) level (students showed elevated levels of lipids and BMI-based obesity more than normotensive students. TG, HDL, HbA1c, and cholesterol appeared to influence pre-hypertension.

    It is known that the metabolic syndrome (MS), which includes hypertension, dislipidemia, glucose intolerance, and obesity leads to cardiovascular diseases. The MS risk is growing catastrophically. Molecular mechanisms allowing to understand the reason of integrated dysfunctions, taking place at MS cases, have remained almost unstudied. The chronical stress plays a crucial role in MS development; therefore in the present work a hypertensive rat strain with Inherited Stress-Induced Arterial Hypertension (ISIAH) was used as a model. It was shown that ISIAH rat strain as compared with the control WAG rat strain is characterized by increased content of triglyceride, VLDL and LDL cholesterols, a decreased content of HDL cholesterol, a high level of apolipoprotein B-100, and decreased level of apolipoprotein A-I. The ISIAH rats body weight was higher as compared with WAG rats; ISIAH rats blood glucose content was higher too. Thus, strain hypertension for ISIAH rat is accompanied by dislipidemia, increased glucose content, and increased body weight, representing a whole set of MS signs. Since at MS cases the systemic abnormalities in lipid and carbohydrate metabolism take place, the functional activity of transcription factors (TFs) participating in integral regulation of lipid and carbohydrate metabolism genes in liver was measured. PPAR, LXR, PXR, CAR DNA-binding activity was increased in ISIAH rats, suggesting involvement of these TFs in MS development. Integrated investigation of PPAR, LXR, PXR, CAR regulatory mechanisms, signal transduction and transcriptional targets will provide insights into the pathogenesis of MS and offer valuable information for designing of drugs for MS treatment.

    Hypertension affects 30% of adults worldwide. Garlic supplements have shown promise in the treatment of uncontrolled hypertension, and the mechanism of action is biologically plausible. Our trial is the first to assess the effect of aged garlic extract on central blood pressure and arterial stiffness, regarded as important risk factors for cardiovascular morbidity. A total of 88 general practice patients and community members with uncontrolled hypertension completed a double-blind randomized placebo-controlled trial of 12 weeks investigating the effect of daily intake of aged garlic extract (1.2 g containing 1.2 mg S-allylcysteine) or placebo on blood pressure, and secondary outcome measures of central-hemodynamics and other cardiovascular markers, including cholesterol, homocysteine, platelet function, and inflammatory markers. Mean blood pressure was significantly reduced by 5.0±2.1 mmHg (P=0.016) systolic, and in responders by 11.5±1.9 mmHg systolic and 6.3±1.1 mmHg diastolic compared to placebo (Pblood pressure, central pulse pressure, mean arterial pressure, augmentation pressure, pulse-wave velocity, and arterial stiffness. While changes in other cardiovascular markers did not reach significance due to small numbers in subgroups with elevated levels, trends in beneficial effects of garlic on the inflammatory markers TNFα, total cholesterol, low-density lipid cholesterol, and apolipoproteins were observed. Aged garlic extract was highly tolerable and acceptable, and did not increase the risk of bleeding in patients on blood-thinning medication. Our trial suggests that aged garlic extract is effective in reducing peripheral and central blood pressure in a large proportion of patients with uncontrolled hypertension, and has the potential to improve arterial stiffness, inflammation, and other cardiovascular markers in patients with elevated levels. Aged garlic extract was highly tolerable with a high safety profile as a stand-alone or adjunctive

    RNA interference (RNAi) high-content screening (HCS) enables massive parallel gene silencing and is increasingly being used to reveal novel connections between genes and disease-relevant phenotypes. The application of genome-scale RNAi relies on the development of high quality HCS assays. The Z' factor statistic provides a way to evaluate whether or not screening run conditions (reagents, protocols, instrumentation, kinetics, and other conditions not directly related to the test compounds) are optimized. Z' factor, introduced by Zhang et al., ( 1) is a dimensionless value that represents both the variability and the dynamic range between two sets of sample control data. This paper describe a new extension of the Z' factor, which integrates bioinformatics RNAi non-target compounds for screening quality assessment. Currently presented Z' factor is based on positive and negative control, which may not be sufficient for RNAi experiments including oligonucleotides (oligo) with lack of knock-down. This paper proposes an algorithm which extends existing algorithm by using additional controls generetaed from on-target analysis.

    Full Text Available Background. Elevated blood pressure has been reported among treatment naïve HIV-infected patients. We investigated prevalence of hypertension and its associated risk factors in a HAART naïve HIV-infected population in Dar es Salaam, Tanzania. Methods. A cross-sectional analysis was conducted among HAART naïve HIV-infected patients. Hypertension was defined as systolic blood pressure (SBP ≥ 140 mmHg and/or diastolic blood pressure (DBP ≥ 90 mmHg. Overweight and obesity were defined as body mass index (BMI between 25.0–29.9 kg/m2 and ≥30 kg/m2, respectively. We used relative risks to examine factors associated with hypertension. Results. Prevalence of hypertension was found to be 12.5%. After adjusting for possible confounders, risk of hypertension was 10% more in male than female patients. Patients aged ≥50 years had more than 2-fold increased risk for hypertension compared to 30–39-years-old patients. Overweight and obesity were associated with 51% and 94% increased risk for hypertension compared to normal weight patients. Low CD4+ T-cell count, advanced WHO clinical disease stage, and history of TB were associated with 10%, 42%, and 14% decreased risk for hypertension. Conclusions. Older age, male gender, and overweight/obesity were associated with hypertension. Immune suppression and history of TB were associated with lower risk for hypertension. HIV treatment programs should screen and manage hypertension even in HAART naïve individuals.

    Full Text Available Abstract Background The aim of this study was to determine which behavioral factors to include in guidelines for the Japanese public to achieve an acceptable level of oral healthiness. The objective was to determine the relationship between oral health related behaviors and symptoms related to oral disease and tooth loss in a Japanese adult community. Methods Oral health status and lifestyle were investigated in 777 people aged 20 years and older (390 men and 387 women. Subjects were asked to complete a postal questionnaire concerning past diet and lifestyle. The completed questionnaires were collected when they had health examinations. The 15 questions included their preference for sweets, how many between-meal snacks they usually had per day, smoking and drinking habits, presence of oral symptoms, and attitudes towards dental visits. Participants were asked about their behaviors at different stages of their life. The oral health examinations included examination of the oral cavity and teeth performed by dentists using WHO criteria. Odds ratios were calculated for all subjects, all 10 year age groups, and for subjects 30 years or older, 40 years or older, 50 years or older, and 60 years or older. Results Frequency of tooth brushing (OR = 3.98, having your own toothbrush (OR = 2.11, smoking (OR = 2.71 and bleeding gums (OR = 2.03 were significantly associated with number of retained teeth in males. Frequency of between-meal snacks was strongly associated with number of retained teeth in females (OR = 4.67. Having some hobbies (OR = 2.97, having a family dentist (OR = 2.34 and consulting a dentist as soon as symptoms occurred (OR = 1.74 were significantly associated with number of retained teeth in females. Factors that were significantly associated with tooth loss in both males and females included alcohol consumption (OR = 11.96, males, OR = 3.83, females, swollen gums (OR = 1.93, males, OR = 3.04, females and toothache (OR = 3.39, males, OR

    Introduction Hypertension (HT) has its origin in childhood and adolescent period but it goes undetected due to absence of sign and symptoms, unless specifically looked for during this period. It has been seen that one with raised blood pressure level in this period will also have raised Blood Pressure (BP) level in their adulthood and elderly period. Aim The present study was conducted to estimate the prevalence of HT and its risk factor among apparently healthy school going adolescents of Patna district. Materials and Methods A cross-sectional study among 2913 school going adolescents of eighth to 10th standard was conducted from April 2014 to August 2015 by adopting a two stage cluster sampling technique. The questions pertaining to risk behavior in relation to cardiovascular diseases from WHO’s Global School based Student Health Survey were used for this study. Results The mean systolic and diastolic blood pressure of study population was 107.4 mm of Hg (95% C.I. 106.93-107.77) and 67.4 mm of Hg (95% C.I. 67.26-67.54), respectively. Prevalence of pre-HT and HT was 10.9% and 4.6% in school going adolescents while prevalence of overweight/obesity was 1.5%. Both systolic and diastolic blood pressures had positive and significant correlation with age, height and body mass index. The proportion of children who had ever taken tobacco was 5.3%, cigarette smoking 4.3%, alcohol consumption 2.1%, and excess salt intake 22.3%. Only 49.1% children were doing physical activity at least one hour a day in past seven days for maintenance of good health. Conclusion The present study recommends that regular screening of blood pressure level must be initiated in adolescents so that remedial measure can be initiated as early as possible.

    Liberalisation of the electricity market has led to Danish gas engine plants increasingly converting to the spot and regulating power markets. In order to offer regulating power, plants need to be able to start and stop the engines at the plants quickly. The liberalisation causes a considerable change of operation practice of the engines e.g. less full load operation hours /year. The project provides an inventory determining the scale of the emissions during the start and stop sequence as well as proposals for engine modifications aimed at reducing start/stop emissions. This report includes calculation of emission factors as well as an inventory of total emissions and reduction potentials. (au)

    Hypertension is a major risk factor for non-communicable diseases. Yet, Nation-wide prevalence and trend reports in developing countries are sparsely available. Data from three cycles of Survey of Risk Factors of Non-communicable Diseases (SuRFNCD) 2005 - 2011 were aggregated. In 2011, 8218 adults aged 25 - 70 years were enrolled. For trend analysis 68850, 4184, and 7416 adults aged 25 - 64 years were included from 2005, 2007, and 2011 surveys, respectively. Hypertension was defined as systolic blood pressure (SBP) ≥ 140 mmHg, diastolic blood pressure (DBP) ≥ 90 mmHg, or receiving anti-hypertensive medication. Pre-hypertension was defined as SBP between 120 - 139 or DBP between 80 - 89 mmHg. The status of awareness, non-pharmacologic treatment (management), pharmacologic treatment, and control (SBP hypertensive individuals were also determined. 25.6% (95%CI: 23.5 - 27.5) of the adults aged 25 - 70 years had hypertension and 39.8% (95%CI: 37.8 - 41.9) had pre-hypertension. The prevalence of hypertension was greater among older adults (P adults with hypertension (25.7% to 24.1%) and pre-hypertension (45.5% to 40.4%) significantly decreased. In 2011, rates for awareness, management, treatment, and control among hypertensives were 43.2% (95%CI: 40.0 - 46.4), 40.3% (95%CI: 37.0 - 43.6), 34.8% (95%CI: 31.5 - 38.2), and 38.6% (95%CI: 33.1 - 44.2), respectively. Over time, status of awareness, management, treatment and control was significantly improved and was more salient among men (P hypertension and pre-hypertension is gradually declining. Despite improvements in awareness, management, treatment and control, these decline rates are still low and initiative strategies need to be implemented to further improve the current status.

    Background Low adherence to hypertension (HT) management is one of the major contributors to poor blood pressure (BP) control. Approximately 40%–60% of patients with HT do not follow the prescribed treatment. The aim of the study was to analyze the relationship between selected variables and adherence to hypotensive pharmacological treatment. Besides socioclinical variables, the study focused on the role of illness acceptance. Participants and methods The study included 602 patients with HT. Adherence and acceptance of illness were assessed using the following validated instruments: the Acceptance of Illness Scale (AIS) and the Morisky Medication Adherence Scale (MMAS). Results The high-adherence group comprised a significantly higher percentage of patients with high illness acceptance scale scores than that of patients with low-to-moderate scores (42.4 vs 31.8%; P=0.0081.5 times as likely to occur in the high acceptance group as in the low-to-moderate acceptance group (OR =1.58, 95% CI 1.14–2.19). Spearman’s rank correlation coefficients showed statistically significant correlations between adherence and sex (men ρ=−0.101; P=0.012), age >45–66 years (ρ=0.098; P=0.015), higher education level (ρ=0.132; P=0.001), grade ESC of HT (ρ=−0.037; P=0.057), receiving one-tablet polytherapy (ρ=0.131; P=0.015), and illness acceptance (ρ=0.090; P=0.024). Conclusion Acceptance of illness is correlated with adherence to pharmacological treatment, and consideration should be given to more widespread assessment of illness acceptance in daily practice. Male sex, age >45–66 years, duration of illness grade ESC of HT, and receiving one-tablet polytherapy are significant determinants of adherence to pharmacological treatment in HT. PMID:28280309

    The aim of this study was to estimate prevalence and severity of renal insufficiency in systemic sclerosis (SSc) and to assess risk factors associated with reduced glomerular filtration rate (GFR) in SSc patients. Seventy-three consecutive patients with SSc (67 women and 6 men), mean age 56.2 years, mean disease duration 6.7 years, were included in this cross-sectional study. GFR was measured by creatinine clearance (CCr) in all patients, as well as 24-h proteinuria. We assessed frequency and severity of renal insufficiency in our patients with SSc and estimated the association of renal insufficiency with age, disease duration, subtype of the disease, earlier diagnosed arterial hypertension, and medications for which we assumed to affect renal function-cytostatics, nonsteroidal anti-inflammatory drugs, glucocorticoids, ACE inhibitors, diuretics, and calcium channel blockers (CCB). Fifty-six out of 73 patients with SSc (76.7%) had reduced GFR (CCr lower than 90 ml/min), compared to 17/73 (23.3%) of patients with normal renal function. Mild renal insufficiency was noticed in 28/73 (38.4%), moderate in 21/73 (28.8%) and severe renal insufficiency in 5/73 (6.8%). End-stage renal disease (CCr arterial hypertension and treatment with glucocorticoids are independent risk factors for reduced GFR. On the other hand, age, disease duration, disease form, as well as antibodies (anticentromere antibodies-ACA and anti-topoisomerase I antibodies-ATA) were excluded as independent risk factors. Patients with SSc and arterial hypertension treated with CCB had significantly higher mean CCr than patients treated with diuretics (90.4 vs 53.5 ml/min, p = 0.03), or patients treated with ACE inhibitors (90.4 vs 41.7 ml/min, p = 0.001). Decreased GFR is common in SSc. Most of patients have mild or moderate renal insufficiency. Previously diagnosed arterial hypertension, especially when treated with ACE inhibitors or diuretics, and glucocorticoids are independent risk factors

    High blood pressure is increasing worldwide, disproportionately so in developing countries. Inadequate health care systems and adoption of unhealthy lifestyles have been linked to this emergent pattern. To better understand this trend, it is imperative we measure prevalence of hypertension, and examine specific risk factors, at a local level. This study provides a cross-sectional view of urban residents of Arusha City to determine prevalence and associated risk factors. Blood pressure was measured using a digital sphygmomanometer. Interviews were conducted using the WHO STEPwise survey questionnaire to assess lifestyle factors. Dietary intake information was collected by a standardized Food Frequency Questionnaire (FFQ). Descriptive statistics were used to analyze demographic characteristics. Means and standard deviations were calculated for continuous variables and percentages for categorical variables. Pearson's Chi Square (χ (2)) tests were used to determine significant risk factors for hypertension, and multivariate log binomial regression was used to reveal potential predictors of hypertension. Dietary patterns were analyzed by principal component analysis. Approximately 45% of the study population was found to be hypertensive. The mean arterial blood pressure (MABP) of the sample was 102.3 mmHg (SD = 18.3). Mean systolic and diastolic blood pressure were 136.3 (SD = 30.5) and 85.3 (SD = 16.1) mmHg, respectively. Through multivariate analysis, age and body mass index were found to be independently, positively, associated with hypertension. Adherence to 'healthy' dietary pattern was negatively independently associated with hypertension. With nearly half of participants being hypertensive, this study suggests that hypertension is a significant health risk in Arusha, Tanzania. Obesity, healthy diet, and age were found to be positively associated with hypertension risk. This study did not establish any significant association between increased blood

    Full Text Available Maria Czarina AcelajadoVascular Biology and Hypertension Program, Division of Cardiovascular Disease, University of Alabama at Birmingham, Birmingham, AL, USAAbstract: Hypertension is a common and important modifiable risk factor for cardiovascular and kidney diseases. The prevalence of hypertension, particularly isolated systolic hypertension, increases with advancing age, and this is partly due to the age-related changes in the arterial tree, leading to an increase in arterial stiffness. Therapeutic lifestyle changes, such as reduced dietary sodium intake, weight loss, regular aerobic activity, and moderation of alcohol consumption, have been shown to benefit elderly patients with hypertension. Lowering blood pressure (BP using pharmacological agents reduces the risk for cardiovascular morbidity and mortality, with no difference in risk reduction in elderly patients compared to younger hypertensives. Guidelines recommend a BP goal of <140/90 in hypertensive patients regardless of age and <130/80 in patients with concomitant diabetes or kidney disease, and lowering the BP further has not been shown to confer any additional benefit. Moreover, the choice of antihypertensive does not seem to be as important as the degree of BP lowering. Special considerations in the treatment of elderly hypertensive patients include cognitive impairment, dementia, orthostatic ­hypotension, and polypharmacy.Keywords: hypertension, elderly, treatment, blood pressure

    Previous assessments of the prevalence of resistant hypertension (RH) in uncontrolled blood pressure (BP) have ranged from 3% to 30%. Using real-world data, our aim was to estimate the prevalence of RH in patients belonging to the Maccabi Healthcare Services, a 2-million-member health organization in Israel. From 2010 to 2011, all hypertensive patients with ≥2 recorded BP measurements during a minimum period of 6 months were identified. Patients were considered uncontrolled if their most recent BP during the study period and their mean systolic BP or diastolic BP during a preceding period of ≥6months were systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg, or systolic BP ≥130 mm Hg or diastolic BP ≥80 mm Hg in chronic kidney disease or diabetes mellitus. Uncontrolled patients taking diuretics and ≥2 antihypertensive therapy classes at their maximal recommended dose were regarded as resistant hypertensives. A total of 172 432 patients were eligible for the study. Uncontrolled BP was found in 35.9% (n=65 710). Overall, 2.2% of the uncontrolled patients (n=1487) were resistant hypertensives. Patients with RH were characterized by a significantly (Phypertension receiving equivalent treatment. The results of this large population-based study indicate a substantially lower prevalence of RH than previously reported. Most patients with uncontrolled BP took less than the maximal recommended antihypertensive treatment.

    The aim of this study was to provide additional evidences on prognostic factors for infantile spasms and the possible role of a ketogenic diet. A retrospective analysis was performed for patients with infantile spasms who had been followed up for more than 6months between January 2000 and July 2012 at Samsung Medical Center (Seoul, Republic of Korea). We analyzed the association between possible prognostic factors and seizure/developmental outcomes. Sixty-nine patients were included in this study and their mean follow-up duration was 52.5 (9-147) months. In the patients who had been followed up for more than 2years, 53.6% (n=30/57) remained seizure-free at the last visit. Sixty patients (86.9%) showed developmental delay at last follow-up. Forty-two patients (60.9%) became spasm-free with one or two antiepileptic drugs, one patient with epilepsy surgery for a tumor, and seven patients with a ketogenic diet after the failure of two or more antiepileptic drugs. The etiology and age of seizure onset were the significant prognostic factors. In this study, about 60% of the patients became spasm-free with vigabatrin and topiramate. Ketogenic diet increased the rate by 10% in the remaining antiepileptic drug resistant patients. However, 86.9% of the patients showed developmental delay, mostly a severe degree. Early diagnosis and prompt application of treatment options such as antiepileptic drugs, a ketogenic diet or epilepsy surgery can improve outcomes in patients with infantile spasms.

    Socioeconomic inequalities in physical activity at the individual level are well reported. Whether inequalities in economic development and other macroenvironmental variables between countries are also related to physical activity at the country level is comparatively unstudied. We examined the relationship between country-level data on macroenvironmental factors (gross domestic product (GDP) per capita, public sector expenditure on health, percentage living in urban areas, and cars per 1000 population) with country-level physical activity prevalence obtained from previous pan-European studies. Studies that assessed leisuretime physical activity (n = 3 studies including 27 countries in adults, n = 2 studies including 28 countries in children) and total physical activity (n = 3 studies in adults including 16 countries) were analyzed separately as were studies among adults and children. Strong and consistent positive correlations were observed between country prevalence of leisure-time physical activity and country GDP per capita in adults (average r = 0.70; all studies, P G 0.05). In multivariate analysis, country prevalence of leisure-time physical activity among adults remained associated with country GDP per capita (two of three studies) but not urbanization or educational attainment. Among school-age populations, no association was found between country GDP per capita and country prevalence of leisure-time physical activity. In those studies that assessed total physical activity (which also includes occupational and transport physical activity), no association with country GDP per capita was observed. Clear differences in national leisure-time physical activity levels throughout Europe may be a consequence of economic development. Lack of economic development of some countries in Europe may make increasing leisure-time physical activity more difficult.

    Arterial Hypertension (AH) is a disease with multiple risk factors (RF), and it is one of the most important risk factor for cardiovascular diseases. The objective of this study was to determine the prevalence of AH in Sobremonte area and its correlation to other risk factors. The study was done in an special programme called "Solidarity in Health" (SIH) supported by the College of Medicine at the National University of Córdoba, which provided primary care to residents of Cachi Yaco (Sobremonte Department). It is an small village near Santiago del Estero province located in 226 km from Córdoba city. They went to the city and they examined the patients at the the "French and Berutti" school for nine consecutive years (2000-2008). Sobremonte area is the poorest deparment in the province of Córdoba and it has the highest rate of lowest socio-economic development, and a very deficient health care system.. The only hospital providing primary care is in San Francisco del Chañar, and the access is not free. The study involved the determination of the arterial pressure (AP) according to the seventh "JNC"criteria, body mass index (BMI), levels of alcohol consumption, exercise, salt consumption, diabetes and smoking in all the patients. Additionally, three water samples from different representative zones were collected and tested for sodium concentration. 471 patients were included. The incidence of AH was 43.5% of the patients. (51% men and 36% women). Higher incidence of AH was found in patients between 50 and 59 years old. There was a stadistical difference in the BMI, diabetes, and alcohol consumption between healthy patients and patients with AH. There was not any correlation between AH and exercise. We found higher levels of sodium in the water of this area and it was between 13-35 higher than in C6rdoba city and it was correlated with AH. We conclude that the increased sodium consumption is one of the most important risk factor of AH in this population.

    Full Text Available Resistant hypertension in adolescents is increasing in frequency and is increasingly recognized as having significant short- and long-term health consequences. It may be seen in up to 30% of all hypertensive patients cared for. Adolescents with resistant hypertension are at higher cardiovascular (CV risk due to a long history of severe hypertension complicated by other CV risk factors such as obesity. Common causes of resistant hypertension include primary aldosteronism, sleep apnea, diabetes and chronic kidney disease. Careful blood pressure (BP measurement and thorough evaluation of patients with sustained BP elevation should make a possible early diagnosis of resistant hypertension. Successful treatment requires identification and reversal of life-style factors contributing to treatment resistant and diagnosis and appropriate treatment of causes of hypertension. Improved pharmacologic therapies may offer the potential for preventing or at least ameliorating early CV disease. This review highlights these and other important issues in the evaluation and management of adolescents with resistant hypertension and provides practical guidance to the practitioners involved in caring for such patients.

    Few data exist on whether healthy lifestyle factors are associated with better prognosis among individuals with apparent treatment-resistant hypertension, a high-risk phenotype of hypertension. The purpose of this study was to assess the association of healthy lifestyle factors with cardiovascular events, all-cause mortality, and cardiovascular mortality among individuals with apparent treatment-resistant hypertension. We studied participants (n=2043) from the population-based Reasons for Geographic and Racial Differences in Stroke (REGARDS) study with apparent treatment-resistant hypertension (blood pressure ≥140/90 mm Hg despite the use of 3 antihypertensive medication classes or the use of ≥4 classes of antihypertensive medication regardless of blood pressure control). Six healthy lifestyle factors adapted from guidelines for the management of hypertension (normal waist circumference, physical activity ≥4 times/week, nonsmoking, moderate alcohol consumption, high Dietary Approaches to Stop Hypertension diet score, and low sodium-to-potassium intake ratio) were examined. A greater number of healthy lifestyle factors were associated with lower risk for cardiovascular events (n=360) during a mean follow-up of 4.5 years. Multivariable-adjusted hazard ratios [HR (95% confidence interval)] for cardiovascular events comparing individuals with 2, 3, and 4 to 6 versus 0 to 1 healthy lifestyle factors were 0.91 (0.68-1.21), 0.80 (0.57-1.14), and 0.63 (0.41-0.95), respectively (P-trend=0.020). Physical activity and nonsmoking were individual healthy lifestyle factors significantly associated with lower risk for cardiovascular events. Similar associations were observed between healthy lifestyle factors and risk for all-cause and cardiovascular mortality. In conclusion, healthy lifestyle factors, particularly physical activity and nonsmoking, are associated with a lower risk for cardiovascular events and mortality among individuals with apparent treatment

    Small reductions in blood pressure reduce the risk of cardiovascular events. Here, we report 2 post hoc pooled analyses assessing the antihypertensive effect of amlodipine in patients who had not responded to 5 mg and were uptitrated to 10 mg. The first analysis assessed subgroups of patients aged either younger than 55 years or 55 years or older and the second analysis pooled all patients irrespective of age. Of 706 patients in the age-related analysis, a statistically significant decrease in blood pressure from baseline was observed {for younger than 55 years [N = 253]: systolic blood pressure = -12.8 [standard error (SE) = 0.90] mm Hg, diastolic blood pressure = -8.0 [SE = 0.55] mm Hg; for 55 years or older [N = 453]: systolic blood pressure = -12.1 [SE = 0.66] mm Hg, diastolic blood pressure = -6.7 [SE = 0.39] mm Hg; all P 55 and 55 years or older, respectively, achieved their blood pressure goals. Adverse events were experienced by 62 (24.5%) patients aged younger than 55 years and 136 (30.0%) patients aged 55 years or older. Similar efficacy and safety results were seen in the all patient pooled analysis. Titration of amlodipine from 5 mg to 10 mg significantly decreased blood pressure in older hypertensive patients, which is clinically relevant because increased age is associated with hypertension and cardiovascular events.

    The role of fever in trauma patients remains unclear. Fever occurs as a response to release of cytokines and prostaglandins by white blood cells. Many factors, including trauma, can trigger release of these factors. To determine whether (1) fever in the first 48 hours is related to a favorable outcome in trauma patients and (2) fever is more common in patients with head trauma. Retrospective study of trauma patients admitted to the intensive care unit for at least 2 days. Data were analyzed by using multivariate analysis. Of 162 patients studied, 40% had fever during the first 48 hours. Febrile patients had higher mortality rates than did afebrile patients. When adjusted for severity of injuries, fever did not correlate with mortality. Neither the incidence of fever in the first 48 hours after admission to the intensive care unit nor the number of days febrile in the unit differed between patients with and patients without head trauma (traumatic brain injury). About 70% of febrile patients did not have a source found for their fever. Febrile patients without an identified source of infection had lower peak white blood cell counts, lower maximum body temperature, and higher minimum platelet counts than did febrile patients who had an infectious source identified. The most common infection was pneumonia. No relationship was found between the presence of fever during the first 48 hours and mortality. Patients with traumatic brain injury did not have a higher incidence of fever than did patients without traumatic brain injury. About 30% of febrile patients had an identifiable source of infection. Further studies are needed to understand the origin and role of fever in trauma patients. ©2015 American Association of Critical-Care Nurses.

    Patients with hypertension and type 2 diabetes are at increased risk of cardiovascular and chronic renal disease. Factors involved in the pathogenesis of both hypertension and type 2 diabetes include inappropriate activation of the renin-angiotensin-aldosterone system, oxidative stress, inflammation, impaired insulin-mediated vasodilatation, augmented sympathetic nervous system activation, altered innate and adaptive immunity, and abnormal sodium processing by the kidney. The renin-angiotensin-aldosterone system blockade is a key therapeutic strategy in the treatment of hypertension in type 2 diabetes. Emerging therapies for resistant hypertension as often exists in patients with diabetes, include renal denervation and carotid body denervation. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Studies from Sweden have reported association between immigrant status and incidence of cardiovascular diseases. The nature of this relationship is unclear. We investigated the relationship between immigrant status and risk of heart failure (HF hospitalization in a population-based cohort, and to what extent this is mediated by hypertension and life-style risk factors. We also explored whether immigrant status was related to case-fatality after HF. Methods 26,559 subjects without history of myocardial infarction (MI, stroke or HF from the community-based Malmö Diet and Cancer (MDC cohort underwent a baseline examination during 1991-1996. Incidence of HF hospitalizations was monitored during a mean follow-up of 15 years. Results 3,129 (11.8% subjects were born outside Sweden. During follow-up, 764 subjects were hospitalized with HF as primary diagnosis, of whom 166 had an MI before or concurrent with the HF.

    The purpose of this study was to explain the health promotion behavior of Chinese international students in Korea using a structural equation model including acculturation factors. A survey using self-administered questionnaires was employed. Data were collected from 272 Chinese students who have resided in Korea for longer than 6 months. The data were analyzed using structural equation modeling. The p value of final model is .31. The fitness parameters of the final model such as goodness of fit index, adjusted goodness of fit index, normed fit index, non-normed fit index, and comparative fit index were more than .95. Root mean square of residual and root mean square error of approximation also met the criteria. Self-esteem, perceived health status, acculturative stress and acculturation level had direct effects on health promotion behavior of the participants and the model explained 30.0% of variance. The Chinese students in Korea with higher self-esteem, perceived health status, acculturation level, and lower acculturative stress reported higher health promotion behavior. The findings can be applied to develop health promotion strategies for this population. Copyright © 2016. Published by Elsevier B.V.

    To assess the prevalence of hypertension, diabetes, and dyslipidaemia in subjects with subclinical hypothyroidism (SH) in comparison with an age- and sex-matched control group. Case-control study with 240 subjects with SH and 480 controls carried out on patients aged 35-75 years admitted to a Primary Care Centre. The prevalence of hypertension, diabetes and dyslipidaemia, as well as blood pressure, plasma glucose, and lipid profilses, were evaluated in both groups. No differences were observed neither in the prevalence of hypertension (34.2% vs. 29.6%) or diabetes (12.1% vs. 10%) nor in mean values of blood pressure or plasma fasting glucose. Subjects with SH had an increased prevalence of lipid abnormalities (72.1% vs. 57.7%; P<.001), and increased mean values of total cholesterol (205±34 vs. 193±35mg/dL; P<.001), compared to the control group. Patients with SH have an increased prevalence of lipid abnormalities. This can be responsible for an increased cardiovascular risk in such patients. Copyright © 2016 Elsevier España, S.L.U.

    Essential hypertension (EH) is a major public health problem world over and in India. Recent data on EH in the population of Chandigarh (Union Territory and capital of Punjab and Haryana States of India) revealed that the prevalence of EH has become double in the last 30 years in the residents of Chandigarh (26.9 to 45.80% in the year 1968 and 2002). Zinc (Zn), copper (Cu), magnesium (Mg), and manganese (Mn) in the serum are considered important in maintaining the human hypertension. The high Zn intake was considered to increase the blood pressure (BP) and to affect the other mineral status in the body. Recent survey on the trace metal status of different vegetables in the State of Punjab around Chandigarh (India) revealed that Zn level is significantly higher (40 mg/kg or more in above ground vegetables and 120 mg/kg or above in underground vegetables) in underground water-irrigated vegetables, but the levels of Cu and Mg are within prescribed limit. The present study was conducted on Chandigarh population to evaluate the levels of Zn, Cu, Mg, and Mn in the blood and urine of normotensive (NT) control and hypertensive (HT) subjects matched with number, age and sex. Atomic absorption spectrophotometer studies reevaluated that the levels of serum Zn, Mg, and Mn were significantly higher (p < 0.001), but the level of Cu was low in the HT subjects (BP = 160/93) compared to NT control (BP = 140/83). Higher levels of urinary Zn, Cu, Mg, and Mn were observed in the HT subject vs NT control (p < 0.001). Positive correlations were evaluated between the levels of serum Zn, Mg, and Mn vs systolic and diastolic pressures (DP and SP), respectively (r = 0.928, 0.863, 0.876, 0.808, 0.404, 0.326, p < 0.01), but negative and positive nonsignificant correlations between the serum Cu with SP and DP were recorded (r = -0.032, r = 0.024). Positive correlations were also evaluated between urinary levels of Zn, Cu, Mg, and Mn vs SP and DP (r = 0.718, 0.657, 0.750, 0.681, 0.630, 0.578, 0

    The past 2 decades have seen a considerable global increase in cardiovascular disease, with hypertension remaining by far the most common. More than one-third of adults in Africa are hypertensive; as in the urban populations of most developing countries. Being a condition that occurs with relatively few symptoms, hypertension remains underdetected in many countries; especially in developing countries where routine screening at any point of health care is grossly underutilized. Because hypertension is directly related to cardiovascular disease, this has led to hypertension being the leading cause of adverse cardiovascular outcomes, as a result of patients living, often unknowingly, with uncontrolled hypertension for prolonged periods of time. In Africa, hypertension is the leading cause of heart failure; whereas at global levels, hypertension is responsible for more than half of deaths from stroke, just less than half of deaths from coronary artery disease, and for more than one-tenth of all global deaths. In this review, we discuss the escalating occurrence of hypertension in developing countries, before exploring the strengths and weaknesses of different measures to control hypertension, and the challenges of adopting these measures in developing countries. On a broad level, these include steps to curb the ripple effect of urbanization on the health and disease profile of developing societies, and suggestions to improve loopholes in various aspects of health care delivery that affect surveillance and management of hypertension. Furthermore, we consider how the industrial sectors' contributions toward the burden of hypertension can also be the source of the solution.

    Han and Mongolian populations constitute approximately 96% of the population of Inner Mongolia Autonomous Region, and the two ethnic groups have different genetic backgrounds and lifestyle. We aim to assess the prevalence, awareness, treatment, control, and related risk factors of hypertension among urban adults in Inner Mongolia, with the comparison of the differences between Mongolian and Han populations in this respect. Three thousand two hundred fifty-one individuals aged 20-80 years (2326 Han and 925 Mongolian) were selected using a multistage cluster sampling method from Inner Mongolia in 2014. The adjusted prevalence, awareness, treatment and control of hypertension were evaluated by the Logistic regression. In addition, possible interactions were also tested. When interactions were found significant, strata-specific analysis were performed. Multivariate logistic regression was used for estimating independent associations between risk factors and hypertension. The prevalence of hypertension was 27.47% for Han population, 31.46% for Mongolian population. The adjusted prevalence, awareness, treatment and control of hypertension were 26.45, 65.43, 78.24 and 48.28% in Han, and 31.30, 68.22, 85.57 and 50.55% in Mongolian, respectively. There was no significant difference in the adjusted awareness, treatment and control of hypertension among Mongolian and Han adult residents (all P >0.05). Lower prevalence of hypertension was associated with younger age and healthy weight in both Mongolian and Han adults. Within Han adults, high education, moderate physical activity and non-alcohol drinkers were additionally associated with lower prevalence of hypertension, whereas within Mongolian adults, lower prevalence was associated with being female. Among residents with medium education level, nondrinkers had 0.60 times lower odds of having hypertension than current drinkers (OR = 0.60, 95% CI: 0.44-0.82); among residents with high education level, nondrinkers has 0

    Full Text Available OBJECTIVE:The aim of the study was to identify the frequency of risk factors for hypertensive disorders in pregnancy in Southern Brazil. METHODS: The study included 161 patients with hypertensive disorders and 169 control subjects matched by age and ethnicity. The frequency of the risk factors was compared by Fisher's exact test, chi-square and Student's t test. A multivariate logistic regression analysis assessed the independent role of clinical, social and demographic factors which were associated with occurrence of the hypertensive disease in pregnancy in the univariate analysis. RESULTS: Patients enrolled in the study were predominantly Caucasian (73% and the mean age was 29. In the multivariate analysis, the variables associated were: family history of preeclampsia (p = 0.001; OR = 3.88; 95% CI = 1.77-8.46, diabetes (p = 0.021; OR = 3.87; 95% CI = 1.22-12.27 and chronic hypertension (p = 0.002; OR = 7.05; 95% CI = 1.99-24.93. CONCLUSION: The risk factors associated with hypertensive disorders in pregnancy appear to be similar to those reported in other countries. The knowledge of the risk factors could be helpful in a prenatal care.OBJETIVO: Identificar a frequência dos fatores de risco para distúrbios hipertensivos durante a gravidez na região Sul do Brasil.

    the prevalence of all types of cognitive impairment, including dementia, is increasing but knowledge of aetiological factors is still evolving. this study aimed to evaluate the association between cardiovascular risk factors and cognitive function in older persons. a population-based cohort design involving 2,312 men and women (aged 50-75) enrolled in the University of Edinburgh Aspirin for Asymptomatic Atherosclerosis trial. cognitive tests included the Mill Hill Vocabulary Scale, auditory verbal learning test (AVLT), digit symbol test, verbal fluency test (VFT), Raven's Progressive Matrices and the trail making test. A 'g' score (measure of general intelligence) was computed for each subject. Regression analysis was used to evaluate the association between relevant variables. higher diastolic BP was negatively associated with AVLT (β = -0.153, P < 0.01), and with an estimated decline on AVLT (β = -0.125, P < 0.01). Smoking was negatively associated with all the cognitive variables except VFT. The total cholesterol level was not associated with cognitive function or estimated decline. smoking and elevated blood pressure may be risk factors for cognitive decline, and thus potential targets for preventive and therapeutic interventions.

    Hypertension and related cardiovascular diseases are the leading causes of death in many countries. The etiology of human essential hypertension is largely unknown. It is highly likely that hypertension is a complex and multifactorial disease resulting from the interaction of multiple genetic and environmental factors.Animal models of hypertension have been proved to be useful to study the pathogenesis of, and to find a new therapy for, hypertension. The aim of this article is to briefly review the most widely used rodent models of experimental hypertension,including history and recent advances. These models are classified as genetically-induced, environmentally-induced, pharmacologically-induced, and renalinduced hypertension according to the way of induction; the typical representatives of each of these major types of experimental hypertension are spontaneous hypertension, cold-induced hypertension, DOCA-salt-induced hypertension, and renal-induced hypertension, respectively. The processes of induction of hypertension, possible pathogenesis, characteristics, advantages, and limitations of these animal models are reviewed. In addition, the clinical implications of the above experimental models of hypertension are addressed.

    The Dietary Approach to Stop Hypertension (DASH) is recommended to lower blood pressure (BP), but its effects on cardiometabolic biomarkers are unclear. A systematic review and meta-analysis of randomised controlled trials (RCT) was conducted to determine the effects of the DASH diet on cardiovascular risk factors. Medline, Embase and Scopus databases were searched from inception to December 2013. Inclusion criteria were as follows: (1) DASH diet; (2) RCT; (3) risk factors including systolic and diastolic BP and glucose, HDL, LDL, TAG and total cholesterol concentrations; (4) control group. Random-effects models were used to determine the pooled effect sizes. Meta-regression analyses were carried out to examine the association between effect sizes, baseline values of the risk factors, BMI, age, quality of trials, salt intake and study duration. A total of twenty articles reporting data for 1917 participants were included in the meta-analysis. The duration of interventions ranged from 2 to 24 weeks. The DASH diet was found to result in significant decreases in systolic BP ( - 5·2 mmHg, 95% CI - 7·0, - 3·4; PFramingham risk score for CVD. The DASH diet improved cardiovascular risk factors and appeared to have greater beneficial effects in subjects with an increased cardiometabolic risk. The DASH diet is an effective nutritional strategy to prevent CVD.

    Apigenin is a natural flavonoid compound that can inhibit hypoxia-inducible factor (HIF)-1α expression in cultured tumor cells under hypoxic conditions. Hypertension-induced cardiac hypertrophy is always accompanied by abnormal myocardial glucolipid metabolism due to an increase of HIF-1α. However, whether or not apigenin may ameliorate the cardiac hypertrophy and abnormal myocardial glucolipid metabolism remains unknown. This study aimed to examine the effects of apigenin. Rats with cardiac hypertrophy induced by renovascular hypertension were treated with apigenin 50-100 mg kg(-1) (the doses can be achieved by pharmacological or dietary supplementation for an adult person) by gavage for 4 weeks. The results showed that after treatment with apigenin, the blood pressure, heart weight, heart weight index, cardiomyocyte cross-sectional area, serum angiotensin II, and serum and myocardial free fatty acids were reduced. It is important to note that apigenin decreased the expression level of myocardial HIF-1α protein. Moreover, apigenin simultaneously increased the expression levels of myocardial peroxisome proliferator-activated receptor (PPAR) α, carnitine palmitoyltransferase (CPT)-1, and pyruvate dehydrogenase kinase (PDK)-4 proteins and decreased the expression levels of myocardial PPARγ, glycerol-3-phosphate acyltransferase genes (GPAT), and glucose transporter (GLUT)-4 proteins. These findings demonstrated that apigenin could improve hypertensive cardiac hypertrophy and abnormal myocardial glucolipid metabolism in rats, and its mechanisms might be associated with the down-regulation of myocardial HIF-1α expression and, subsequently increasing the expressions of myocardial PPARα and its target genes CPT-1 and PDK-4, and decreasing the expressions of myocardial PPARγ and its target genes GPAT and GLUT-4.

  20. Analysis of Placental Growth Factor in Placentas of Normal Pregnant Women and Women with Hypertensive Disorders of Pregnancy

    2006-01-01

    To investigate the expressions of placental growth factor (PLGF) in placenta with hypertensive disorders of pregnancy (HDP), 45 women with HDP and 20 normally pregnant women were studied. Among 45 women with HDP, there were 23 cases of severe preeclampsia and one case of eclampsia. The location and level of PLGF proteins was determined by immunohistochemistry and Western blot. The expression of PLGF mRNA in placenta was assessed by reverse transcriptionalpolymerase chain reaction (RT-PCR). The results showed that: (1) The distribution of PLGF in placenta with HDP was similar to normal one, which was mainly in the cytoplasm of villous syncytiotrophoblast and villous stroma; (2) The expression of PLGF protein was significantly decreased in placentas with mild and severe preeclampsia compared to the normal ones (0.3±0.4 vs 0.6± 0.4, 0.2±0.5 vs 0.6±0. 4, P<0.01). There were no differences between the gestational hypertension placenta and normal one (0.5±0.6 vs 0.6±0.4, P>0. 05); (3) The transcription levels of the PLGF mRNA in placentas with preeclampsia were significantly lower than in normal groups (3.33±0.39 vs4.87±0.60, 1.97±0.29 vs 4.87±0. 60, P<0.01), and no differences were found between the gestational hypertension placenta and normal groups. These findings suggest that the abnormal expression of PLGF in placentas is related to the pathogenesis of HDP.

    To explore the role of the atrial natriuretic factor (ANF) system in the pathophysiology of hypertension we examined the binding kinetics of synthetic ANF to cultured vascular smooth muscle cells (VSMCs) derived from the spontaneously hypertensive rat (SHR) and two normotensive controls-the Wistar Kyoto (WKY) and American Wistar (W). The number of maximal binding sites (Bmax) per cell (mean +/- SEM; X10(3) were: SHR = 278.0 +/- 33.0, WKY = 28.3 +/- 7.1 and W = 26.6 +/- 4.2. The differences between the SHR and normotensive strains were significant at p less than 0.001. The equilibrium dissociation constant (Kd; X 10(-9)M) was higher in SHR VSMCs (0.94 +/- 0.14) than in WKY (0.22 +/- 0.09; p less than 0.01) and W (0.39 +/- 0.14; p less than 0.02) cells. The plasma levels of the immunoreactive ANF were higher in SHR than the normotensive controls. We suggest that the relatively greater ANF receptor density in cultured VSMCs of the SHR represents a response to the in vitro environment which is relatively more deficient in ANF for VSMCs of the SHR as compared with the normotensive rats. Thus, the capacity of the SHR VSMC to regulate ANF receptor density appears to be independent of the blood pressure level.

    Starting from the existence of some autoimmune diseases (i.e. bronchial asthma or miastenia gravis) we asked ourselves if some plasmatic factors do exist, influencing the receptor--mediator relations in cardiovascular system during some illnesses having unknown etiology, as arterial hypertension. For this reason, in this work was tested the hypothesis that, in some chronic cardiovascular diseases would exist factors circulating and affecting the functions of the cellular membranes of the arterial wall, particularly of the smooth muscle cells and myocardial cells. Our results show a significant modification of the calcium fluxes and of some neuromediators uptake at the hypertensive patients.

  9. Reactive oxygen species and vascular biology: implications in human hypertension.

    Increased vascular production of reactive oxygen species (ROS; termed oxidative stress) has been implicated in various chronic diseases, including hypertension. Oxidative stress is both a cause and a consequence of hypertension. Although oxidative injury may not be the sole etiology, it amplifies blood pressure elevation in the presence of other pro-hypertensive factors. Oxidative stress is a multisystem phenomenon in hypertension and involves the heart, kidneys, nervous system, vessels and possibly the immune system. Compelling experimental and clinical evidence indicates the importance of the vasculature in the pathophysiology of hypertension and as such much emphasis has been placed on the (patho)biology of ROS in the vascular system. A major source for cardiovascular, renal and neural ROS is a family of non-phagocytic nicotinamide adenine dinucleotide phosphate (NADPH) oxidases (Nox), including the prototypic Nox2 homolog-based NADPH oxidase, as well as other Noxes, such as Nox1 and Nox4. Nox-derived ROS is important in regulating endothelial function and vascular tone. Oxidative stress is implicated in endothelial dysfunction, inflammation, hypertrophy, apoptosis, migration, fibrosis, angiogenesis and rarefaction, important processes involved in vascular remodeling in hypertension. Despite a plethora of data implicating oxidative stress as a causative factor in experimental hypertension, findings in human hypertension are less conclusive. This review highlights the importance of ROS in vascular biology and focuses on the potential role of oxidative stress in human hypertension.

    Full Text Available BACKGROUND: Antihypertensive drugs are believed to lower blood pressure in pre-eclampsia by direct or central vasodilatory mechanisms. However, they could also act by decreasing production of anti-angiogenic proteins involved in the pathophysiology of hypertension and proteinuria in pre-eclampsia (PE. The aim of our study was to evaluate the impact of antihypertensive therapy with alpha methyldopa on maternal circulating levels and placental production of soluble fms-like tyrosine kinase 1 (sFlt-1, soluble endoglin (sEng, vascular endothelial growth factor (VEGF and placental growth factor (PlGF in hypertensive disorders of pregnancy. METHODOLOGY/PRINCIPAL FINDINGS: In a study conducted at University College Hospital and the Homerton University Hospital in London, we recruited 51 women with PE, 29 with gestational hypertension (GH, and 80 matched normotensive controls. Eight (16% of the women with PE had severe disease. Placental samples were obtained from a further 48 women (14 PE, 10 GH and 24 matched controls. Serum levels of angiogenic factors were measured before and 24-48 hours after commencing antihypertensive therapy with alpha methyldopa for clinical indications. The same parameters were measured in placental extracts. In both PE (P<0.0001 and GH (P<0.05, serum sFlt-1 was increased and PlGF reduced at all gestations (P<0.001 compared to controls. Serum sEng levels were also increased in PE. Placental concentration of sFlt-1 and sEng was significantly higher in women with PE compared to controls and women with GH (P<0.0001. The concentration of PlGF was significantly lower in the placental tissue of women with PE compared to GH (P = 0.008. Antihypertensive treatment was associated with a significant fall in serum and placental content of sFlt1 and sEng in PE only. CONCLUSIONS: Our data suggest that alpha methyldopa may have a specific effect on placental and/or endothelial cell function in pre-eclampsia patients, altering angiogenic

    Full Text Available Aims. To evaluate the prognostic significance of serum interleukin-6 (IL-6 in colorectal cancer (CRC. Patients and Methods. Preoperative serum IL-6 was measured in 233 CRC patients and 13 healthy controls. Relationships between IL-6 and various clinicopathological factors were evaluated, and the overall survival (OS and disease-free survival (DFS rates according to IL-6 status were calculated for all patients and according to disease stage. Results. The mean IL-6 level was 6.6 pg/mL in CRC patients and 2.6 pg/mL in healthy controls. Using a cutoff of 6.3 pg/mL, obtained using receiver operating characteristic curve analysis, 57 patients had a high IL-6 level. The mean value was higher for stage II disease than for stage III disease. IL-6 status correlated with C-reactive protein (CRP and carcinoembryonic antigen levels, obstruction, and pT4 disease. The OS differed according to the IL-6 status for all patients, whereas the DFS differed for all patients and for those with stage II disease. The Cox proportional hazards model showed that pT4 disease was an independent risk factor for recurrence in all CRC patients; IL-6, CRP, and pT4 were significant risk factors in stage II patients. Conclusions. The preoperative IL-6 level influences the risk of CRC recurrence.

    The aim of this chapter is to revise some common views on changes in pubertal timing. This revision is based on recent epidemiological findings on the clinical indicators of pubertal timing and data on environmental factor effects and underlying mechanisms. A current advancement in timing of female puberty is usually emphasized. It appears, however, that timing is also changing in males. Moreover, the changes are towards earliness for initial pubertal stages and towards lateness for final stages in both sexes. Such observations indicate the complexity of environmental influences on pubertal timing. The mechanisms of changes in pubertal timing may involve both the central neuroendocrine control and peripheral effects at tissues targeted by gonadal steroids. While sufficient energy availability is a clue to the mechanism of pubertal development, changes in the control of both energy balance and reproduction may vary under the influence of common determinants such as endocrine-disrupting chemicals (EDCs). These effects can take place right before puberty as well as much earlier, during fetal and neonatal life. Finally, environmental factors can interact with genetic factors in determining changes in pubertal timing. Therefore, the variance in pubertal timing is no longer to be considered under absolutely separate control by environmental and genetic determinants. Some recommendations are provided for evaluation of EDC impact in the management of pubertal disorders and for possible reduction of EDC exposure along the precautionary principle.

    Hypertension is a common problem in the diabetic population with estimates suggesting a prevalence exceeding 60%. Comorbid hypertension and diabetes mellitus are associated with high rates of macrovascular and microvascular complications. These two pathologies share overlapping risk factors, importantly central obesity. Treatment of hypertension is unequivocally beneficial and improves all-cause mortality, cardiovascular mortality, major cardiovascular events, and microvascular outcomes including nephropathy and retinopathy. Although controversial, current guidelines recommend a target blood pressure in the diabetic population of diabetes. Management of blood pressure in patients with diabetes includes both lifestyle modifications and pharmacological therapies. This article reviews the evidence for management of hypertension in patients with type 2 diabetes mellitus, and provides a recommended treatment strategy based on the available data.

    To investigate whether a proactive multifactorial risk factor intervention strategy using single-pill amlodipine/atorvastatin (5/10, 10/10 mg) in addition to other antihypertensive and lipid-lowering therapy, as required, resulted in greater reduction in calculated Framingham 10-year coronary heart disease (CHD) risk compared with usual care (UC) after 52-weeks treatment. Prospective, multinational, open-label, cluster randomized trial, with the investigator as the unit of randomization. Eligible hypertensive patients were 35-79 years of age, with ≥3 additional cardiovascular risk factors, but no history of CHD and baseline total cholesterol (TC) ≤6.5 mmol/l. www.ClinicalTrials.gov ; trial identifier NCT00407537. The primary endpoint was calculated Framingham 10-year CHD risk at 52 weeks. Of the 140 randomized sites, 136 sites contributed 1461 patients. Mean baseline age and low-density lipoprotein cholesterol (LDL-C) were comparable between treatment arms. Mean baseline BP (150.3/89.7 vs. 144.3/86.5 mmHg) and Framingham CHD risk (20.0 vs. 18.1%) were higher in the proactive intervention versus the UC arm (p risk was 12.5% in the proactive intervention arm and 16.3% in the UC arm (p safety experience for this medication. A proactive multifactorial risk factor intervention strategy that simultaneously treated both BP and cholesterol regardless of individual risk factors per se, is more effective in reducing calculated Framingham 10-year CHD risk than UC in patients with hypertension and additional risk factors.

    Arterial hypertension is the most common chronic disease in developed countries and it is the leading risk factor for stroke, ischemic heart disease, congestive heart failure, chronic renal failure and peripheral artery disease. Its prevalence appears to be about 30-45% of the general population. Recent European guidelines estimate that up to 15-20% of the hypertensive patients are not controlled on a dual antihypertensive combination and they require three or more different antihypertensive drug classes to achieve adequate blood pressure control. The guidelines confirmed that diuretics, beta-blockers, calcium-channel blockers, angiotensin-converting enzyme inhibitors and angiotensin receptor blockers are suitable for the initiation and maintenance of antihypertensive treatment, either as monotherapy or in combination therapy. Very few antihypertensive agents have reached the market over the last few years, but no new therapeutic class has really emerged. The long-term adherence to cardiovascular drugs is still low in both primary and secondary prevention of cardiovascular diseases. In particular, the issue of compliance is persistently high in hypertension, despite the fixed-dose combination therapy. As a consequence, a cohort of high-risk hypertensive population, represented by patients affected by refractory and resistant hypertension, can be identified. Therefore, the need of controlling BP in high-risk patients may be addressed, in part, by the development of new drugs, devices and procedures that are designed to treat hypertension and comorbidities. In this review we will comprehensively discuss the current literature on recent therapeutic advances in hypertension, including both medical therapy and interventional procedures.

  2. Hypoxia-inducible factor-1 alpha regulates the role of vascular endothelial growth factor on pulmonary arteries of rats with hypoxia-induced pulmonary hypertension

    2004-01-01

    Background Hypoxia-inducible factor-1α (HIF-1α) is one of the pivotal mediators in the response of lungs to decreased oxygen availability, and increasingly has been implicated in the pathogenesis of pulmonary hypertension. Vascular endothelial growth factor (VEGF), a downstream target gene of HIF-1α, plays an important role in the pathogenesis of hypoxic pulmonary hypertension and hypoxic pulmonary artery remodelling. In this study, we investigated the dynamic expression of HIF-1α and VEGF in pulmonary artery of rats with hypoxia-induced pulmonary hypertension. Methods Forty male Wistar rats were exposed to hypoxia for 0, 3, 7, 14 or 21 days. Mean pulmonary arterial pressure (mPAP), vessel morphometry and right ventricle hypertrophy index (RVHI) were estimated. Lungs were inflated and fixed for in situ hybridisation and immunohistochemistry. Results mPAP values were significantly higher than the control values after 7days of hypoxia [(18.4±0.4) mmHg, P<0.05]. RVHI developed significantly after 14 days of hypoxia. Expression of HIF-1α protein increased in pulmonary arterial tunica intima of all hypoxic rats. In pulmonary arterial tunica media, HIF-1α protein was markedly increased by day 3 (0.20±0.02, P<0.05), reached the peak by day 7, then declined after day 14 of hypoxia. HIF-1α mRNA increased significantly after day 14 of hypoxia (0.20±0.02, P<0.05). VEGF protein began to increase markedly after day 7 of hypoxia, reaching its peak around day 14 of hypoxia (0.15±0.02, P<0.05). VEGF mRNA began to increase after day 7 of hypoxia, then remained more or less stable from day 7 onwards. VEGF mRNA is located mainly in tunica intima and tunica media, whereas VEGF protein is located predominantly in tunica intima. Linear analysis showed that HIF-1α mRNA, VEGF and mPAP were correlated with hypoxic pulmonary artery remodelling. HIF-1α mRNA was positively correlated with VEGF mRNA and protein (P<0.01). Conclusion HIF-1α and VEGF are both involved in the

    Relativistic models for finite nuclei contain spurious center-of-mass motion in most applications for the nuclear many-body problem, where the nuclear wave function is taken as a single Slater determinant within a space-fixed frame description. We use the Peierls-Yoccoz projection method, previously developed for relativistic approaches together with a reparametrization of the coupling constants that fits binding energies and charge radius and apply our results to calculate elastic electron scattering monopole charge form factors for light nuclei.

    Full Text Available Problem statement. For planning and organization of urban construction is necessary to analyze the use of areas. Territorial resources of the city, being used for construction and other urban purposes, consists of plots of land: disposable, reserved and undeveloped in previous years of construction in progress; residential districts and blocks of obsolete housing fund; industrial and municipal and warehouse enterprises being used irrationally or stopped to work; the defence department, where the amortized warehouses and other main funds are that are not used by purpose; agricultural enterprises where the obsolete industrial funds, haying, nurseries, greenhouses. The number of free areas suitable for future urban development is extremely limited. However a considerable part of the territories of almost all functional zones is used inefficiently. Purpose. Formalization of a factor of investment attractiveness of territories for the further identification and research of the connection between it and the cost of housing construction is necessary. Conclusion. The identification of regularities of influence of the factor of investment attractiveness of territories on the cost of construction of high-rise buildings allow to obtain a quantitative estimate of this effect and can be used in the development of the methodology of substantiation of the expediency and effectiveness of the implementation of highrise construction projects, based on organizational and technological aspects.

    Full Text Available Resistant hypertension (RH is characterized by blood pressure above 140 × 90 mm Hg, despite the use, in appropriate doses, of three antihypertensive drug classes, including a diuretic, or the need of four classes to control blood pressure. Resistant hypertension patients are under a greater risk of presenting secondary causes of hypertension and may be benefited by therapeutical approach for this diagnosis. However, the RH is currently little studied, and more knowledge of this clinical condition is necessary. In addition, few studies had evaluated this issue in emergent countries. Therefore, we proposed the analysis of specific causes of RH by using a standardized protocol in Brazilian patients diagnosed in a center for the evaluation and treatment of hypertension. The management of these patients was conducted with the application of a preformulated protocol which aimed at the identification of the causes of resistant hypertension in each patient through management standardization. The data obtained suggest that among patients with resistant hypertension there is a higher prevalence of secondary hypertension, than that observed in general hypertensive ones and a higher prevalence of sleep apnea as well. But there are a predominance of obesity, noncompliance with diet, and frequent use of hypertensive drugs. These latter factors are likely approachable at primary level health care, since that detailed anamneses directed to the causes of resistant hypertension are applied.

In order to make this paradigm operational, safety management and in particular risk assessment tools need to be refined....... A valuable approach is the inclusion of human and organisational factors into the simulation of the reliability of the technical system using event trees and fault trees and the concept of safety barriers. This has been demonstrated e.g. in the former European research project ARAMIS (Accidental Risk...... Assessment Methodology for IndustrieS, see Salvi et al 2006).

Patients who receive insufficient doses of antihypertensive agents or who are poorly adherent to multidrug treatment regimens often fail to achieve adequate blood pressure (BP control. The aim of this study was to determine the efficacy of an angiotensin II receptor blocker (ARB and calcium channel blocker (CCB combination tablet containing a regular dose of irbesartan (100 mg and a high dose of amlodipine (10 mg with regard to lowering BP and other risk factors for cardiovascular disease.Methods: We retrospectively evaluated data from 68 patients with essential hypertension whose treatment regimen was changed either from combination treatment with an independent ARB and a low-dose or regular-dose CCB or from a combination tablet of ARB and a low-dose or regular-dose CCB to a combination tablet containing amlodipine 10 mg and irbesartan 100 mg, because of incomplete BP control. Previous treatments did not include irbesartan as the ARB.Results: The combination tablet decreased systolic and diastolic BP. In addition, it significantly decreased serum uric acid, low-density lipoprotein cholesterol, and increased high

  10. Endothelial cell processing and alternatively spliced transcripts of factor VIII: potential implications for coagulation cascades and pulmonary hypertension.

    Full Text Available BACKGROUND: Coagulation factor VIII (FVIII deficiency leads to haemophilia A. Conversely, elevated plasma levels are a strong predictor of recurrent venous thromboemboli and pulmonary hypertension phenotypes in which in situ thromboses are implicated. Extrahepatic sources of plasma FVIII are implicated, but have remained elusive. METHODOLOGY/PRINCIPAL FINDINGS: Immunohistochemistry of normal human lung tissue, and confocal microscopy, flow cytometry, and ELISA quantification of conditioned media from normal primary endothelial cells were used to examine endothelial expression of FVIII and coexpression with von Willebrand Factor (vWF, which protects secreted FVIII heavy chain from rapid proteloysis. FVIII transcripts predicted from database mining were identified by RT-PCR and sequencing. FVIII mAb-reactive material was demonstrated in CD31+ endothelial cells in normal human lung tissue, and in primary pulmonary artery, pulmonary microvascular, and dermal microvascular endothelial cells. In pulmonary endothelial cells, this protein occasionally colocalized with vWF, centered on Weibel Palade bodies. Pulmonary artery and pulmonary microvascular endothelial cells secreted low levels of FVIII and vWF to conditioned media, and demonstrated cell surface expression of FVIII and vWF Ab-reacting proteins compared to an isotype control. Four endothelial splice isoforms were identified. Two utilize transcription start sites in alternate 5' exons within the int22h-1 repeat responsible for intron 22 inversions in 40% of severe haemophiliacs. A reciprocal relationship between the presence of short isoforms and full-length FVIII transcript suggested potential splice-switching mechanisms. CONCLUSIONS/SIGNIFICANCE: The pulmonary endothelium is confirmed as a site of FVIII secretion, with evidence of synthesis, cell surface expression, and coexpression with vWF. There is complex alternate transcription initiation from the FVIII gene. These findings provide a

    Full Text Available Biomarkers have been identified for pulmonary arterial hypertension, but are less well defined for specific etiologies such as congenital heart disease-associated pulmonary arterial hypertension (CHDPAH. We measured plasma levels of eight microvascular dysfunction markers in CHDPAH, and tested for associations with survival. A cohort of 46 inoperable CHDPAH patients (age 15.0 to 60.2 years, median 33.5 years, female:male 29:17 was prospectively followed for 0.7 to 4.0 years (median 3.6 years. Plasma levels of von Willebrand factor antigen (VWF:Ag, tissue plasminogen activator (t-PA and its inhibitor (PAI-1, P-selectin, reactive C-protein, tumor necrosis factor alpha, and interleukin-6 and -10 were measured at baseline, and at 30, 90, and 180 days in all subjects. Levels of six of the eight proteins were significantly increased in patients versus controls (13 to 106% increase, P < 0.003. Interleukin-10 level was 2.06 times normal (P = 0.0003; Th2 cytokine response. Increased levels of four proteins (t-PA, PAI-1, P-selectin, and interleukin-6 correlated with disease severity indices (P < 0.05. Seven patients died during follow-up. An average VWF:Ag (mean of four determinations above the level corresponding to the 95th percentile of controls (139 U/dL was independently associated with a high risk of death (hazard ratio = 6.56, 95%CI = 1.46 to 29.4, P = 0.014. Thus, in CHDPAH, microvascular dysfunction appears to involve Th2 inflammatory response. Of the biomarkers studied, plasma vWF:Ag was independently associated with survival.

    In Russia, blood pressure (BP) control is below the optimal. The little is known about regional features and barriers to adequate BP control in Russian primary care. To evaluate the impact of clinical factors on achieving the target BP in hypertensive patients in one region of Russia. Retrospective medical data of 2015 on 11,129 patients (31.4% male) with hypertension (Htn) from Ivanovo region of Russia were examined. Achievement of target BP was assessed in all patients. We study association between BP control and clinical factors. 45.9% of studied patients with Htn had controlled BP. The frequency of achieving the target BP in subsets of hypertensive patients was 37.8% in patients with diabetes, 39.5% in patients with coronary artery disease, and 29.9% in patients with chronic heart failure. The main clinical factors associated with achieving the target BP in studied hypertensive patients were the advice on alcohol consumption, advice on smoking cessation, and advice on weight reduction. Therapy with main antihypertensive drugs (in particular, beta-blockers and thiazide diuretics) were also factors of optimal BP control in these patients. Comorbidities (chronic heart failure and cardiovascular diseases requiring the prescription of aspirin and statins) and family history of coronary artery disease were associated with inadequate BP control. A negative effect of some antihypertensive drugs (potassium sparing diuretics, ARBs, ACE-Is, and dihydropyridine CCBs) on BP control that was found out in our study requires further investigation. Other studied factors had no influence on BP control in patients with Htn from Ivanovo region. We identified regional factors of BP control in hypertensive patients from Ivanovo region of Russia. It is shown that individual medical education (in particular, medical advices) is the most important factor of optimal BP control. The intervention with antihypertensive therapy (beta-blockers and thiazide diuretics) facilitates the

    An altered hormonal or chronic systemic inflammatory milieu characterizing endometriosis may result in a higher risk of hypercholesterolemia and hypertension. Conversely, elevated low-density lipoprotein in hypercholesterolemia and chronic systemic inflammation resulting from hypertension may increase the risk of endometriosis. We assessed the association of laparoscopically confirmed endometriosis with hypercholesterolemia and hypertension in a large prospective cohort study. In 1989, 116 430 registered female nurses aged 25 to 42 completed the baseline questionnaire and were followed for 20 years. Multivariable Cox proportional hazards models were applied. In 1989, there were 4244 women with laparoscopically confirmed endometriosis and 91 554 women without. After adjusting for demographic, anthropometric, family history, reproductive, dietary, and lifestyle risk factors prospectively, comparing women with laparoscopically confirmed endometriosis to women without, the relative risks were 1.25 (95% confidence interval, 1.21-1.30) for development of hypercholesterolemia and 1.14 (95% confidence interval, 1.09-1.18) for hypertension. Conversely, the relative risks of developing laparoscopically confirmed endometriosis were 1.22 (95% confidence interval, 1.15-1.31) comparing women with hypercholesterolemia to women without and 1.29 (95% confidence interval, 1.18-1.41) comparing women with hypertension to women without. The strength of associations of laparoscopically confirmed endometriosis with hypercholesterolemia or hypertension was strongest among women aged ≤40 and weakened as age increased (P values for interaction hypercholesterolemia and hypertension could be accounted for by treatment factors after endometriosis diagnosis, including greater frequency of hysterectomy/oophorectomy and earlier age for this surgery. In this large cohort study, laparoscopically confirmed endometriosis was prospectively associated with increased risk of hypercholesterolemia

    Full Text Available Health inequalities: differences in health status or in the distribution of health determinants between different population groups. Some health inequalities are attributable to biological variations or free choice and others are attributable to the external environment and conditions mainly outside the control of the individuals concerned. 347 million people worldwide have diabetes. In 2012 an estimated 1.5 million deaths were directly caused by diabetes. More than 80% of diabetes deaths occur in low- and middle-income countries. WHO projects that diabetes will be the 7th leading cause of death in 2030. Healthy diet, regular physical activity and maintaining a normal body weight can prevent or delay the onset of type 2 diabetes. Risk factors: 1. Age- the prevalence of diabetes rises steeply with age: *one in twenty people over the age of 65 have diabetes, *and this rises to one in five people over the age of 85 years. The diagnosis of diabetes may be delayed in older people, with symptoms of diabetes being wrongly attributed to ageing. 2. Ethnic: type 2 diabetes is up to six times more common in people of South Asian descent and up to three times more common in those of African and African-Caribbean descent then in the white population. It is also more common in people of Chinese descent and other non-Caucasian groups. 3. Gender: the frequency of diabetes usually is higher in men than in women. This may be because gender compounds other aspects of inequality- women often bear the brunt of poverty, and socio-economic differences in the prevalence of diabetes are more marked for women, probably because of differences in smoking rates, food choices and the prevalence of obesity. 4. Overweight/Obesity: every 1 kg/m2 more causes increase risk: cardiovascular diseases 2%, coronary artery disease- 3% , myocardial infarction- 5% , heart failure- 5% , peripheral vascular disease- 5%.

    Hypertension is one of the major risk factors of cardiovascular diseases, but despite a century of clinical and basic research, the discrete etiology of this disease is still not fully understood. The same is true for obesity, which is recognized as a major global epidemic health problem nowadays. Obesity is associated with an increasing prevalence of the metabolic syndrome, a cluster of risk factors including hypertension, abdominal obesity, dyslipidemia, and hyperglycemia. Epidemiological studies have shown that excess weight gain predicts future development of hypertension, and the relationship between BMI and blood pressure (BP) appears to be almost linear in different populations. There is no doubt that obesity-related hypertension is a multifactorial and polygenic trait, and multiple potential pathogenetic mechanisms probably contribute to the development of higher BP in obese humans. These include hyperinsulinemia, activation of the renin-angiotensin-aldosterone system, sympathetic nervous system stimulation, abnormal levels of certain adipokines such as leptin, or cytokines acting at the vascular endothelial level. Moreover, some genetic and epigenetic mechanisms are also in play. Although the full manifestation of both hypertension and obesity occurs predominantly in adulthood, their roots can be traced back to early ontogeny. The detailed knowledge of alterations occurring in the organism of experimental animals during particular critical periods (developmental windows) could help to solve this phenomenon in humans and might facilitate the age-specific prevention of human obesity-related hypertension. In addition, better understanding of particular pathophysiological mechanisms might be useful in so-called personalized medicine.

    Abstract Gestational hypertension (GH) and preeclampsia (PE) are characterized by an imbalance in angiogenic factors. However, the relationship among these factors with the severity of hypertensive disorders of pregnancy (HDP) and adverse outcomes are not fully elucidated. We examined whether these biomarkers are related with the severity of HDP and adverse outcomes. Using a cross-sectional design, serum concentrations of placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFlt-1), and soluble endoglin were determined in 764 pregnant women: 75 healthy pregnant, 83 with mild GH (mGH), 105 with severe GH (sGH), 122 with mild PE (mPE), and 379 with severe PE (sPE). All angiogenic factors’ concentrations were significantly different (P ≤ 0.041) in HDP than in healthy pregnancy. In addition, these factors were markedly different in sPE than in mPE, sGH, or mGH (P ≤ 0.027) and in patients with sGH that in those with mPE or mGH (P < 0.05). As compared to mGH and mPE, patients with sGH and sPE had higher rates of both preterm delivery at <34 weeks of gestation and small-for-gestational age infants. Moreover, patients with sPE had higher rates of adverse maternal outcomes (P < 0.001) when compared to patients with mGH, sGH, or mPE. In all cases, levels of sFlt-1/PlGF ratio were significantly higher in patients with sGH and sPE who had adverse perinatal and maternal outcomes than in those with sGH and sPE who did not (P ≤ 0.016). Circulating concentrations of angiogenic factors appear to be suitable markers to assess the severity of GH and PE, and adverse outcomes. PMID:28121958

    The present study analyzed the relationship between obesity and high blood pressure among nursing professionals of a philanthropic institution, with a view to the early detection of possible cases of hypertension. The study population consisted of 147 nursing professionals of ages between 20-70 years. The researcher performed structured, individual, interviews at the work site of those professionals, 91.8% of which were women; 29.2% were older than 40 years; 11.6% had a SBP > or = 140 mmHg and 6.8% DBP > or = 90 mmHg; 12.2% had obesity class I-II; 38.1% of women with a WHP > or = 0.85, 12.2% in the age range of 40-49 years; 2.1% of men with a WHR > or = 1.0, 1.4% in the age range of 40-49 years. It was found that, though nursing professionals know the severity of the disease and the importance of changing their life habits, they still find it difficult to adopt that behavior, which suggests the need to implement educational programs at the work site to help them to change their behaviors.

    This report shows the antioxidant effects of a hemp seed meal protein hydrolysate (HMH) in spontaneously hypertensive rats (SHR). Defatted hemp seed meal was hydrolyzed consecutively with pepsin and pancreatin to yield HMH, which was incorporated into rat feed as a source of antioxidant peptides. Young (8-week old) SHRs were divided into three groups (8 rats/group) and fed diets that contained 0.0%, 0.5% or 1.0% (w/w) HMH for eight weeks; half of the rats were sacrificed for blood collection. After a 4-week washout period, the remaining 20-week old SHRs were fed for an additional four weeks and sacrificed for blood collection. Plasma total antioxidant capacity (TAC) and superoxide dismutase (SOD), catalase (CAT) and total peroxides (TPx) levels were determined. Results showed that plasma TAC, CAT and SOD levels decreased in the older 20-week old SHRs when compared to the young SHRs. The presence of HMH in the diets led to significant (p < 0.05) increases in plasma SOD and CAT levels in both young and adult SHR groups; these increases were accompanied by decreases in TPx levels. The results suggest that HMH contained antioxidant peptides that reduced the rate of lipid peroxidation in SHRs with enhanced antioxidant enzyme levels and total antioxidant capacity.

    Hypertension is increasingly common in overweight and obese children. The mechanisms behind the development of hypertension in obesity are complex, and evidence is limited. In order to effectively treat obese children for hypertension, it is important to have a deeper understanding of the pathophysiology of hypertension in obese children. The present review summarizes the main factors associated with hypertension in obese children and discusses their potential role in its pathophysiology. Systematic searches were conducted in PubMed and EMBASE for articles published up to October 2014. In total, 60 relevant studies were included. The methodological quality of the included studies ranged from weak to strong. Several factors important in the development of hypertension in obese children have been suggested, including endocrine determinants, such as corticosteroids and adipokines, sympathetic nervous system activity, disturbed sodium homeostasis, as well as oxidative stress, inflammation and endothelial dysfunction. Understanding the pathophysiology of hypertension in overweight and obese children is important and could have implications for its screening and treatment. Based on solely cross-sectional observational studies, it is impossible to infer causality. Longitudinal studies of high methodological quality are needed to gain more insight into the complex mechanisms behind the development of hypertension in obese children.

    Hypertension is a known risk factor for arteriosclerosis, and causes both atherosclero= sis of medium-large arteries and arteriolosclerosis of the arterioles. Elevated blood pressure causes damage to the endothelium and vascular wall through both mechanical and humoral factors. We and others have shown that inhibition of the renin-angiotensin system at a 'critical period' during the development of hypertension results in a permanent suppression of hypertension in animal models. We have also reported that high-dose renin-angiotensin inhibition results in regression of hypertension, possibly by regression of renal arteriolar hypertrophy. These results suggest that understanding the process of arterial remodeling may play a key role in the development of new strategies for prevention and regression of hypertension and arteriosclerosis.

    Imbalanced matrix metalloproteinase (MMP) activity is involved in hypertensive cardiac hypertrophy. Pharmacological inhibition of nuclear factor kappaB (NF-кB) with pyrrolidine dithiocarbamate (PDTC) can prevent MMP up-regulation. We suggested that treatment with PDTC could prevent 2-kidney, 1-clip (2K1C) hypertension-induced left ventricular remodelling. Sham-operated controls or 2K1C rats with hypertension received either vehicle or PDTC (100 mg/kg/day) by gavage for 8 weeks. Systolic blood pressure was monitored every week. Histological assessment of left ventricles was carried out with haematoxylin/eosin sections, and fibrosis was quantified in picrosirius red-stained sections. Oxidative stress was evaluated in heart samples with the dihydroethidium probe. Cardiac MMP activity was determined by in situ zymography, and cardiac MMP-2 was assessed by immunofluorescence. 2K1C surgery significantly increased systolic blood pressure in the 2K1C vehicle. PDTC exerted antihypertensive effects after 2 weeks of treatment. Histology revealed increased left ventricular and septum wall thickness associated with augmented myocyte diameter in hypertensive rats, which were reversed by treatment with PDTC. Hypertensive rats developed pronounced cardiac fibrosis with increased interstitial collagen area, increased cardiac reactive oxygen species levels, gelatinase activity and MMP-2 expression. PDTC treatment decreased these alterations. These findings show that PDTC modulates myocardial MMP-2 expression and ameliorates cardiac remodelling in renovascular hypertension. These results suggest that interfering with MMP expression at transcriptional level may be an interesting strategy in the therapy of organ damage associated with hypertension.

    Full Text Available Analysis of the clinical-and-epidemiological parameters of the stroke was carried out and the prevalence of arterial hypertension was studied as one of the leading factors of stroke development among the residents of the small regional settlement of the Moscow Region. The epidemiological data obtained are indicative of the high stroke morbidity. A significant prevalence of the arterial hypertension was found in the population studied as well as an insufficient control and low understanding by patients of the necessity of regular taking antihypertensive drugs.

    In Switzerland, as in other Occidental countries, the prevalence of arterial hypertension (AHT) in the adult population is around 30-40%. Among the causes of secondary AHT, drug induced hypertension is sometimes omitted. Many molecules can induce AHT or worsen it due to an interaction with anti hypertensive drugs. Among these, NSAIDs and anti depressants, widely prescribed, should be used with caution, particularly in patients at risk, namely: those with preexisting AHT, the elderly, or patients suffering from kidney disease, diabetes, and/or heart failure. Increases in blood pressure have also been described with anti-vascular endothelial growth factor (VEGF) drugs, used in the treatment of (metastatic) cancer. A thorough anamnesis of drugs, including over the counter ones, should be performed in every hypertensive patient, and can avoid cumbersome and unnecessary investigations and therapy.

  9. Extracellular Matrix Remodeling of the Umbilical Cord in Pre-eclampsia as a Risk Factor for Fetal Hypertension

    Directory of Open Access Journals (Sweden)

    Lech Romanowicz

    2011-01-01

    Full Text Available The human umbilical cord forms a connection between the placenta and the foetus. It is composed of two arteries and one vein surrounded by Wharton's jelly. Pre-eclampsia is accompanied by extensive remodeling of extracellular matrix of umbilical cord. Matrix metalloproteinases (MMPs are engaged in degradation of extracellular matrix proteins and activation/inactivation of certain cytokines and enzymes. These enzymes will probably play a central role in the release of matrix-embedded cytokines and growth factors. MMP-2 (gelatinase A is the main collagenolytic enzyme of both umbilical artery and vein. Other metalloproteinases are present in several times lower amounts. Reduced activity of collagen-degrading enzymes may be a factor, which enhances the accumulation of collagen and some other proteins in the pre-eclamptic umbilical cord tissues. It seems to be possible that similar alterations occur in other fetal blood vessels. It may result in an increase in peripheral resistance as well as an increase in the blood pressure in the fetal vascular system. Some observations suggest that the raised pressure may persist after birth. Pre-eclampsia may be a factor that evokes an initiation of hypertension in utero and its amplification through childhood and adulthood.

    Full Text Available Background: Hypertensive disorders during pregnancy occur in women with preexisting primary or secondary chronic hypertension, and in women who develop new-onset hypertension in the second half of pregnancy. The present study was undertaken to study the prevalence and correlates of hypertension in pregnancy in a rural block of Haryana. Materials and Methods: This cross-sectional study was carried out in the all 20 subcenters under Community Health Center (CHC Chiri, Block Lakhanmajra. All the pregnant women registered at the particular subcenter at a point of time of visit were included in the study. Appropriate statistical tests were used for analysis. Results: A total of 931 pregnant women were included in the present study. Prevalence of hypertension in pregnancy was found to be 6.9%. Maternal age ΃25 years, gestational period ͳ20 weeks, history of cesarean section, history of preterm delivery, and history of hypertension in previous pregnancy were found to be significantly associated with prevalence of hypertension in pregnancy. Conclusion: Nearly one in 14 pregnant women in rural areas of Haryana suffers from a hypertensive disorder of pregnancy. Early diagnosis and treatment through regular antenatal checkup is a key factor to prevent hypertensive disorders of pregnancy and its complications.

    2013-02-01

    The present review examines the types of hypertension that women may suffer throughout life, their physiopathological characteristics and management. In early life, the currently used low-dose oral contraceptives seldom cause hypertension. Pregnancy provokes preeclampsia, its main medical complication, secondary to inadequate transformation of the spiral arteries and the subsequent multisystem endothelial damage caused by deportation of placental factors and microparticles. Hypertension in preeclampsia is an epiphenomenon which needs to be controlled at levels that reduce maternal risk without impairing placental perfusion. The hemodynamic changes of pregnancy may unmask a hypertensive phenotype, may exacerbate a chronic hypertension, or may complicate hypertension secondary to lupus, renovascular lesions, and pheochromocytoma. On the other hand a primary aldosteronism may benefit from the effect of progesterone and present as a postpartum hypertension. A hypertensive pregnancy, especially preeclampsia, represents a risk for cardiac, vascular and renal disease in later life. Menopause may mimic a pheochromocytoma, and is associated to endothelial dysfunction and salt-sensitivity. Among women, non-pharmacological treatment should be forcefully advocated, except for sodium restriction during pregnancy. The blockade of the renin-angiotensin system should be avoided in women at risk of pregnancy; betablockers could be used with precautions during pregnancy; diuretics, ACE inhibitors and angiotensin receptor antagonists should not be used during breast feeding. Collateral effects of antihypertensives, such as hyponatremia, cough and edema are more common in women. Thus, hypertension in women should be managed according to the different life stages.

    It is inexorable that a proportion of patients with systemic arterial hypertension will develop a hypertensive crisis at some point in their lives. The hypertensive crises can be divided in hypertensive patients with emergency or hypertensive emergency, according to the presence or absence of acute end-organ damage. In this review, we discuss the cardiovascular hypertensive emergencies, including acute coronary syndrome, congestive heart failure, aortic dissection and sympathomimetic hypertensive crises (those caused by cocaine use included). Each is presented in a unique way, although some patients with hypertensive emergency report non-specific symptoms. Treatment includes multiple medications for quick and effective action with security to reduce blood pressure, protect the function of organs remaining, relieve symptoms, minimize the risk of complications and improve patient outcomes.

    Studies have shown alarming levels of hypertension among adults in the Middle East. The aim of our study is to measure the prevalence rate of hypertension among adults in Cairo (Egypt), identify possible risk factors for the development of hypertension and assess the rates of undiagnosed and uncontrolled hypertension. Cluster sampling was utilized and the fieldwork was conducted by 12 teams; each team consisted of a house officer, community worker and senior epidemiologist. A formulated questionnaire that addresses risk factors for hypertension was filled by all participants. Also, weight and height measurements were done to calculate the body mass index. Blood pressure measurement was done by calibrated sphygmomanometers. Blood pressure measurement was done twice, and a mean recording was calculated. A case which recorded both systolic blood pressure of ≥140 and diastolic blood pressure of ≥90 was considered hypertensive. The study included 774 adult residents of Al-Waily District (Western Zone of Cairo) in late 2011 and early 2012. The mean age of the study participants was 46.5 (SD 17.9) years. Female subjects constituted 67.1% of the studied sample. The prevalence rate of hypertension in our study was 16.5% (95% confidence interval (CI): 13.9-19.3). The rate of hypertension was higher among females and three times higher among obese compared with normal or overweight adults. The prevalence of undiagnosed hypertension was 11% (95% CI: 8.4-13.9), and uncontrolled hypertension was 30% (95% CI: 24.2-37). Community outreach campaigns should be conducted regularly in the future for early detection of hypertension cases and proper health education about hypertension and its dangerous consequences. © The Author 2014.

    Full Text Available This study was a prospective cross-sectional cohort study of 125 patients with sickle cell anemia (SS between the ages of 16 to 60 years. Enrolled patients were followed-up prospectively for 15 months. Demographic, clinical, hematological and routine biochemical data were obtained on all patients. Six-minute walk test and Doppler Echocardiography were performed on all patients. A tricuspid regurgitant jet velocity (TRJV 3.0 m/sec, severe. Patients with abnormal TRJV were significantly older and more anemic, had significantly higher lactate dehydrogenase (LDH levels, reticulocyte count and incidence of death. The logistic multimodal model implemented for the 125 patients indicated that age was the covariate that influenced the outcome of normal or abnormal TRJV with a cutoff age of thirty-two years. The survival rate for the group of patients with creatinine (Cr > 1.0 mg/dL was lower than the group with Cr ≤ 1 and normal TRJV. A coefficient matrix showed that the LDH values were weakly correlated with the reticulocyte count but strongly correlated with hemoglobin suggesting that the TRJV values were not correlated with the hemolytic rate but with anemia. Ten patients died during the follow-up of whom 7 had TRJV > 2.5 m/sec. Acute chest syndrome was the most common cause of death followed by sepsis. In conclusion, this study shows that patients with SS older than thirty-two years with high LDH, elevated TRJV, severe anemia and Cr > 1 have poor prognosis and may be at risk of having pulmonary hypertension and should undergo RHC.

    During fertile life women are usually normo or hypotensive. Hypertension may appear during pregnancy and this represents a peculiar phenomenon increasing nowadays for delay time of pregnancy. Gestational hypertension appears partially similar to hypertension in the context of metabolic syndrome for a similar condition of increased waste circumference. Parity, for the same pathogenesis, has been reported to be associated to peri and postmenopausal hypertension, not confirmed by our study of parous women with transitional non persistent perimenopausal hypertension. Estrogen's deficiency inducing endothelial dysfunction and increased body mass index are the main cause for hypertension in this phase of life. For these reasons lifestyle modification, diet and endothelial active drugs represent the ideal treatment. Antioxidant agents may have a role in prevention and treatment of hypertension. In conclusion, hypertension in women represents a peculiar constellation of different biological and pathogenic factors, which need a specific gender related approach, independent from the male model.

    Hypertension is the most common chronic disease in industrialized countries and represents the most common major cardiovascular risk factor after the fifth decade of life in both men and women. The prevalence of hypertension is lower in premenopausal women than men, whereas in postmenopausal women it is higher than in men. Mechanisms responsible for the increase in blood pressure are complex and multifactorial, including loss of estrogen, oxidative stress, endothelial dysfunction, modification in renin-angiotensin system spillover and sympathetic activation. In addition, postmenopausal hypertension can be considered an isolated disease, more typical of elderly women, or part of the metabolic syndrome, which is indeed more common in early postmenopausal women. In particular, metabolic syndrome may be considered a potentially unfavourable prognostic factor in hypertensive postmenopausal women, because it seems to worsen the severity of hypertension and reduce the capacity to respond to specific treatments. This article summarizes the different causes of postmenopausal hypertension and the specific treatment recommended by guidelines for this condition.

    Full Text Available Essential Hypertension is considered as an important independent risk factor for decline cognitive function leading to dementia and stroke. We assess cognitive function of essential hypertension over 60 years of age and its association with various socio-demographic in Indian setting. This cross sectional study includes 62 hypertensives (stage 1 and 2 as cases and 21 normotensives and 41 prehypertensives as comparison group. Cases and comparison group were age and sex matched. Data was collected through interview and investigations. Cognitive function was measured by minimental status examination scale. In hypertensives, total mean MMSE score as well as the score for orientation, attention-calculation, immediate recall and language (except registration was significantly less compared to normotensives (p<0.001 and prehypertensives (p<0.001. Similar trend was observed for hypertensives with age, gender, education, smoking and alcohol (p<0.001. The overall MMSE scores in prehypertensives and normotensives were almost similar. SBP, DBP and age shows independently statistically significant inverse relationship with cognitive function. Measuring the cognitive function in essential hypertensive patients may have important health implication, as cognitive function along with WML are considered as a prognostic factor for stroke and early marker of brain damage.

Secular trends in adolescent prehypertension and hypertension have risen in congruence with increasing trends in the prevalence of overweight and obesity. The correlation between body mass index and blood pressure in adolescence is moderate to strong in most studies and strongest in those classified as overweight or obese. The mechanisms relating to the development of hypertension in overweight adolescents are unclear; however, a number of nonmodifiable and modifiable factors have been implicated. Importantly, certain clinical and biochemical markers in overweight adolescents are indicative of high risk for hypertension, including family history of hypertension and hyperinsulinemia. These characteristics may prove useful in stratifying overweight adolescents as high or low risk of comorbid hypertension. The treatment of overweight and obesity related hypertension in this population focuses on two key modalities: lifestyle change and pharmacotherapy. These approaches focus almost exclusively on weight reduction; however, a number of emerging strategies target hypertension more specifically. Among adolescents with overt hypertension there are also several factors that indicate higher risk of concurrent subclinical disease, persistent adult hypertension, and adult cardiovascular disease. This group may benefit substantially from more

    Full Text Available Background The belief that an individual can influence and control the course of events is a factor which enables a person to overcome difficulties. Some studies, however, have questioned the universality of this statement. This study aims to investigate and explore the relationship between the self-health locus of control and the effectiveness of cooperation in the treatment process in adolescents with chronic diseases. Participants and procedure One hundred and sixty-four adolescent patients suffering from chronic diseases (61 girls and 103 boys ranging from 11 to 17 years old participated in the study. Eighty-seven had primary hypertension and 77 had type 1 diabetes. To investigate their sense of health control we used the Health Locus of Control Scale (HLC. Cooperation in the treatment process was assessed using a 4-item scale completed by a doctor. Results Better results in the treatment were positively correlated with a better internal health locus of control. A negative correlation between the chance health locus of control and results in the treatment was found. Differences in the health locus of control proved to be dependent on gender, age and different clinical groups. Conclusions Health locus of control in patients with chronic diseases seems to be a crucial factor in determining the results of the treatment process in such patients.

    Full Text Available Pulmonary arterial hypertension (PAH is a progressive disease with high morbidity and mortality rates. Research has shown that PAH has a prevalence rate of 10-79% in thalassemia major patients. This cross-sectional study was carried out in 2014 to determine the prevalence and risk factors of PAH in all thalassemia major patients of over 18 years of age in Ilam, Iran. A cardiologist measured systolic pulmonary artery pressure (SPAP by using Doppler echocardiography. SPAP of higher than 25 mm Hg was defined as PAH criterion. The obtained data was analyzed using SPSS, version 17. Of the 36 studied patients, 17 (47.2% were male and 19 (52.8% were female. The mean age of the patients was 26.0±5.6 years. The prevalence of PAH in the thalassemia major patients was estimated to be 47.2% and the mean SPAP was determined to be 26.2±14.6 mm Hg. Among the examined PAH risk factors, only the history of pulmonary disease (0.02 and transfusion (0.03 was found to be significant.

Material and methods. Patients with HT (n=285 and CIHD (n=223 were studied. Questioning of all patients was performed to assess the characteristics of their PB. Differentiated multivariate analysis of activity and efficacy of PB determinants was performed in HT and CIHD patients by the method of step-by-step backward logistic regression. Results. Awareness of the cardiovascular diseases (CVD and its prevention (odds ratio [OR] 6.08 as well as high level of general education (OR=2.29 were the most significant determinants of active PB in HT patients. Sufficient social support (OR=3.77, awareness of CVD and its prevention (OR=3.16 were the most significant determinants of active PB in patients with CIHD. Efficacy of PB in patients with HT and CIHD mostly depends on satisfaction of medical service (OR=10.2 and 6.63, respectively, social support (OR=6.25 and 10.5, respectively, adequate awareness of CVD and its prevention (OR, 6.92 and 6.64, respectively. Conclusion. PB activity and efficacy in patients with HT and CIHD depends on many contributing and impeding factors. Disregarding these factors can result in failure in preventive efforts at both individual and population levels.

    Grading of essential hypertension according to blood pressure (BP) level may not adequately reflect clinical heterogeneity of hypertensive patients. This study was carried out to explore clinical phenotypes in essential hypertensive patients using cluster analysis. This study recruited 513 hypertensive patients and evaluated BP variations with ambulatory blood pressure monitoring. Four distinct hypertension groups were identified using cluster analysis: (1) younger male smokers with relatively high BP had the most severe carotid plaque thickness but no coronary artery disease (CAD); (2) older women with relatively low diastolic BP had more diabetes; (3) non-smokers with a low systolic BP level had neither diabetes nor CAD; (4) hypertensive patients with BP reverse dipping were most likely to have CAD but had least severe carotid plaque thickness. In binary logistic analysis, reverse dipping was significantly associated with prevalence of CAD. Cluster analysis was shown to be a feasible approach for investigating the heterogeneity of essential hypertension in clinical studies. BP reverse dipping might be valuable for prediction of CAD in hypertensive patients when compared with carotid plaque thickness. However, large-scale prospective trials with more information of plaque morphology are necessary to further compare the predicative power between BP dipping pattern and carotid plaque.

Hypertensive crises are classically distinguished into hypertensive urgency and hypertensive emergency depending on end-organ involvement including central nervous system (CNS, heart, eye, and kidney. A severe elevation in blood pressure without evidence of acute target organ damage describes hypertensive urgency. Hypertensive emergency is defined as severe hypertension complicated with severe symptoms or acute target organ dysfunction. (Journal of Current Pediatrics 2011; 9: 133-6

    Hypertension complicates 5% to 7% of all pregnancies. A subset of preeclampsia, characterized by new-onset hypertension, proteinuria, and multisystem involvement, is responsible for substantial maternal and fetal morbidity and is a marker for future cardiac and metabolic disease. This American Society of Hypertension (ASH) position paper summarizes the clinical spectrum of hypertension in pregnancy, focusing on preeclampsia. Recent research breakthroughs relating to etiology are briefly reviewed. Topics include classification of the different forms of hypertension during pregnancy, and status of the tests available to predict preeclampsia, and strategies to prevent preeclampsia and to manage this serious disease. The use of antihypertensive drugs in pregnancy, and the prevention and treatment of the convulsive phase of preeclampsia, eclampsia, with intravenous MgSO(4) is also highlighted. Of special note, this guideline article, specifically requested, reviewed, and accepted by ASH, includes solicited review advice from the American College of Obstetricians and Gynecologists.

    Full Text Available Background. The incidence of hypertension in the Western countries is continuously increasing in the elderly population and remains the leading cause of cardiovascular and morbidity. Methods. we analysed some significant clinical trials in order to present the relevant findings on those hypertensive population. Results. Several studies (SYST-EUR, HYVET, CONVINCE, VALUE, etc. have demonstrated the benefits of treatment (nitrendipine, hydrochrotiazyde, perindopril, indapamide, verapamil, or valsartan in aged hypertensive patients not only concerning blood pressure values but also the other important risk factors. Conclusion. Hypertension is the most prevalent cardiovascular disorder in the Western countries, and the relevance of receiving pharmacological treatment of hypertension in aged patients is crucial; in addition, the results suggest that combination therapy—nitrendipine plus enalapril—could have more benefits than those observed with the use of nitrendipine alone.

    To evaluate plasma levels of angiogenic factors and their association with preeclampsia. Twenty-three women with preeclampsia and nine normotensive pregnant women from the Maternity of Hospital das Clínicas of Belo Horizonte/MG-Brazil were assessed by National High Blood Pressure Education Program Working Group Creteria (NHBPEPWG). The plasma levels of vascular endothelial growth factor (VEGF) and Placental growth factor (PlGF) were determined by ELISA assay. Plasma concentration of PlGF was 12-fold lower in preeclampsia versus non preeclampsia pregnancies. An inverse correlation was observed between PlGF plasma levels and mean arterial pressure (MAP); a decrease in 1pg/mL of PlGF resulted in 6.18 mm Hg increase in MAP. These results indicate that PlGF is related to MAP in pregnant women.

    Pulmonary hypertension is a progressive disease of various origins that is associated with right ventricular dysfunction. In the present study, the protective effect of diosgenin was investigated in monocrotaline-induced pulmonary hypertension in rats. Pulmonary hypertension was induced by a single subcutaneous injection of monocrotaline (60 mg/kg). Diosgenin (100 mg/kg) was given by oral administration once daily for 3 weeks. At the end of the experiment, mean arterial blood pressure, electrocardiography and echocardiography were recorded. Rats were then sacrificed and serum was separated for determination of total nitrate/nitrite level. Right ventricles and lungs were isolated for estimation of oxidative stress markers, tumor necrosis factor-alpha, total nitrate/nitrite and transforming growth factor-beta contents. Myeloperoxidase and caspase-3 activities in addition to endothelial and inducible nitric oxide synthase protein expression were also determined. Moreover, histological analysis of pulmonary arteries and cardiomyocyte cross-sectional area was performed. Diosgenin treatment provided a significant improvement toward preserving hemodynamic changes and alleviating oxidative stress, inflammatory and apoptotic markers induced by monocrotaline in rats. Furthermore, diosgenin therapy prevented monocrotaline-induced changes in nitric oxide production, endothelial and inducible nitric oxide synthase protein expression as well as histological analysis. These findings support the beneficial effect of diosgenin in pulmonary hypertension induced by monocrotaline in rats. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available High blood pressure (BP is considered as a strong predisposing factor for cardiovascular diseases (CVD Environmental and genetic factors may have a role in high blood pressures. Nutrition has a potential role in the prevention of hypertension and its sequelae. Effect of lowering blood pressure by modification of complex dietary patterns may be the result of synergism between the various components of certain foods or food combinations rather than of the specific effect of a particular nutrient. Vegetarian Diet, Mediterranean Diet, and Dash Diet are three food patterns which have been associated with lowering BP. Vegetarian Diet are characterized by high intake of legumes, nuts, vegetables, and fruits. A relatively high polyunsaturated to saturated fat ratio will make by this kind of diet. Low fat content and high potassium, magnesium, and fiber content of this diet, all factors possibly cooperating to the reduction of blood pressure. Mediterranean Diet has low animal and dairy products as well as saturated fatty acids and cholesterol; it is rich in plant food, legumes, fiber, and antioxidant vitamins with olive oil as the main source of fat. The dietary approaches to stop hypertension (DASH is a success process in control of hypertension, which emphasizes vegetables and fruits and dairy foods with low-fat, it also includes more nuts, poultry, fish, and, whole grains and lower amounts of red meat, fats, sweets, and sugar-containing beverages. DASH diet is poorer in total and saturated fat and cholesterol and richer in potassium, magnesium, calcium, and fiber in comparison to the habitual Western diet. In conclusion, although multiple dietary factors can influence on BP and each factor has a modest effect; the combined effects of those factors can be substantial. In the current study, we review food patterns, lifestyle, and their relationship with hypertension and the possible mechanisms involved.

    Hypertension and diabetes prevalence is high in Africans. Data from HIV infected populations are limited, especially from Malawi. Integrating care for chronic non-communicable co-morbidities in well-established HIV services may provide benefit for patients by preventing multiple hospital visits but will increase the burden of care for busy HIV clinics. Cross-sectional study of adults (≥18 years) at an urban and a rural HIV clinic in Zomba district, Malawi, during 2014. Hypertension and diabetes were diagnosed according to stringent criteria. Proteinuria, non-fasting lipids and cardio/cerebro-vascular disease (CVD) risk scores (Framingham and World Health Organization/International Society for Hypertension) were determined. The association of patient characteristics with diagnoses of hypertension and diabetes was studied using multivariable analyses. We explored the additional burden of care for integrated drug treatment of hypertension and diabetes in HIV clinics. We defined that burden as patients with diabetes and/or stage II and III hypertension, but not with stage I hypertension unless they had proteinuria, previous stroke or high Framingham CVD risk. Nine hundred fifty-two patients were enrolled, 71.7% female, median age 43.0 years, 95.9% on antiretroviral therapy (ART), median duration 47.7 months. Rural and urban patients' characteristics differed substantially. Hypertension prevalence was 23.7% (95%-confidence interval 21.1-26.6; rural 21.0% vs. urban 26.5%; p = 0.047), of whom 59.9% had stage I (mild) hypertension. Diabetes prevalence was 4.1% (95%-confidence interval 3.0-5.6) without significant difference between rural and urban settings. Prevalence of proteinuria, elevated total/high-density lipoprotein-cholesterol ratio and high CVD risk score was low. Hypertension diagnosis was associated with increasing age, higher body mass index, presence of proteinuria, being on regimen zidovudine/lamivudine/nevirapine and inversely with World Health

    To date, accurate reports about the prevalence of high normal blood pressure (BP) and hypertension among Chinese adolescents have been rare. We examine the sex-specific and age-specific prevalence of high normal BP and hypertension, and the associated risk factors among multi-ethnic Chinese adolescents from a large and representative sample. 29,997 adolescents aged 8-18 years old received blood pressure measurement on one clinical visit. The overall prevalence was 4.15% for hypertension (4.73% for boys and 3.62% for girls) and 29.85% for high normal BP (33.40% for boys and 26.65% for girls). The odds ratios (ORs) increased with age, but the absolute changes of ORs were significantly different between boys and girls. Compared with that of the Han counterparts, the risk of high normal BP was 1.960-fold, 1.283-fold and 1.618-fold for Yi boys, Mongolian boys and Yi girls, respectively, whereas the OR was 0.440 for Tibetan boys, 0.492 for Tibetan girls and 0.794 for Korean girls. Compared with those of normal weight, overweight and obese adolescents had significantly increased risk of high normal BP (OR = 3.377 for obese boys and OR = 2.009 for overweight boys; OR = 2.865 for obese girls and OR = 1.738 for overweight girls). Rural adolescents had a higher risk of hypertension than those living in urban areas. The prevalence of high normal BP and hypertension was high
