The present study re-examines the 15% MVC concept, i.e. the existence of a circulatory steady-state in low intensity static contractions below 15% of maximal voluntary contraction (MVC). Mean arterial blood pressure was studied during static endurance contractions of the elbow flexor and extensor...... 0.7) min for elbow extension]. Mean arterial blood pressure exhibited a continuous and progressive increase during the 10% MVC contractions indicating that the 15% MVC concept would not appear to be valid. The terminal blood pressure value recorded at the point of exhaustion in the 10% MVC elbow...... the circulation to the muscles was arrested just prior to the cessation of the contraction, blood pressure only partly recovered and remained elevated for as long as the occlusion persisted, indicating the level of pressure-raising muscle chemoreflexes. Based on blood pressure recordings obtained...

The relation between blood pressure level and degree of global brain atrophy is equivocal. We evaluated past and present blood pressure levels and change in blood pressure over 20 years in relation to the degree of cortical atrophy on magnetic resonance imaging (MRI). In 1995-1996, we measured blood
This study investigated whether low blood-lead levels (≤10 μg/dL) were associated with blood pressure (BP) outcomes. The authors analyzed data from National Health and Nutrition Examination Survey 1999–2006 and participants aged 20 years or older. Outcome variables were systolic and diastolic BP measurements, pulse pressure, and hypertension status. Multivariable linear and logistic regressions stratified by race/ethnicity and gender were performed. Blood lead levels (BLL) were significantly correlated with higher systolic BP among black men and women, but not white or Mexican–American participants. BLLs were significantly associated with higher diastolic BPs among white men and women and black men, whereas, a negative association was observed in Mexican–American men that had, also, a wider pulse pressure. Black men in the 90th percentile of blood lead distribution (BLL≥3.50 μg/dL) compared to black men in the 10th percentile of blood lead distribution (BLL≤0.7 μg/dL) had a significant increase of risk of having hypertension (adjusted POR=2.69; 95% CI: 1.08–6.72). In addition, blood cadmium was significantly associated with hypertension and systolic and diastolic blood. This study found that, despite the continuous decline in blood lead in the U.S. population, lead exposure disparities among race and gender still exist.

In order to evaluate the antihypertensive effectiveness and interaction with ciclosporin A (CS-A) nitrendipine, a dihydropyridine derivative calcium entry blocking agent, was used in 16 (13 men, 3 women) hypertensive renal posttransplant patients followed by the Nephrology Department of Hacettepe University Hospital. The patients did not receive any antihypertensive drug for a 7-day period. They were then given 20 mg/day nitrendipine for 3 weeks. At the end of this period, mean (+/- SE) supine blood pressure fell from 163/108 +/- 3.6/1.87 to 141/87 +/- 3.8/2.2 mm Hg (p less than 0.01), while the heart rate was unchanged. 14 of 16 patients achieved full control of blood pressure levels with 20 mg/day nitrendipine, and only 2 patients needed a higher dosage of 30 mg/day (20 + 10 mg). After 3 weeks of treatment no significant variations in blood chemistry or renal functional parameters were noticed. There was also no difference between blood CS-A levels before and after treatment with nitrendipine (218.06 +/- 33 vs. 222.68 +/- 26 ng/ml, p greater than 0.05). We conclude that short-term therapy with nitrendipine in renal post-transplant patients does not appear to be harmful and longer term studies are needed to fully evaluate safety and efficacy of this drug. Because it influences neither blood chemistry nor renal functional parameters and blood CS-A level, it may be preferable to other calcium channel blocking agents in this group of patients.

Full Text Available Background: Worldwide prevalence of overweight and obesity is increasing and its consequences prompted the WHO to designate obesity as a global epidemic in 2002. Being overweight is a risk factor for significant illness, especially diabetes and hypertension in adult life. Objectives : To study the blood pressure and blood sugar levels and lifestyle parameters in adolescence and comparison with body mass index. Materials and Methods: In a prospective case control study, out of the 1000 screened, a total of 200 adolescents were considered out of which 100 were with high body mass index (BMI and the other 100 were with normal BMI. Height, weight, BMI, waist hip ratio (WHR, blood pressure (BP, BSL, and associated risk factors like physical activity, fast food consumption, and computer/television watching were measured and screened. Results and Observations: 109 (54.5% males and 91 (45.5% females were included. Maximum number [90 (45%] of adolescents screened were in the age group of 17-19 years, while 54 (27% and 56 (28% adolescents were in the age group of 10-13 years and 14-16 years, respectively. According to CDC charts 2000, prevalence of overweight was 24% which was double when compared to WHO charts 2007. There was significant difference in prevalence of obesity; according to CDC chart it was 26%, whereas according to WHO chart it was 39%. The difference in blood pressures between cases and controls as per both CDC and WHO charts was found to be statistically significant (P 0.05 with BMI. Conclusion: The adolescents seem to have become heavier owing to environmental influences on growth patterns. So, a consideration should be given to shift the cut-offs for overweight and obesity to higher BMI percentiles if recent growth charts are to be followed. Adolescents with a BMI above the 95 >th percentile (obese are most likely to have obesity-related health risks.

The problem of correlation between blood pressure levels and intraocular pressure is one of the most talked about. Both, Russian and foreign literature, reflects the heterogeneity of views on the impact of blood pressure changes into the level of intraocular. pressure. At the same time it underestimated the role of systemic cardiovascular changes in the deterioration of visual function in case of primary open-angle glaucoma. Numerous data demonstrate the role of additional factors than average blood pressure levels in advance of glaucoma. More and more researchers tend to assess not only intraocular pressure, but also perfusion pressure as a risk predictor of advance of glaucoma. Correlation between blood pressure level and intraocular pressure has a particular relevance due to the significant improvement of the range of cardiovascular drugs that can affect on intraocular pressure indictors. A number of literature data confirm the need to research variations in blood pressure levels during the day and types of therapy that patients receive. PMID:27120953

Full Text Available Purpose: To evaluate the association between calcium intake from diet, calciotropic hormones (PTH, PTH-rp, vasoactive regulators (endothelin, nitric oxide and blood pressure levels during pregnancy, birth and puerperium.Method: In a prospective study 149 healthy normotensive primigravidas were followed-up from 15 weeks of gestation to puerperium. Daily calcium intake, calciuria, PTH, PTH-rp, endothelin, nitrite-nitrate, and Holter Test were assessed. Linear regression models were performed to evaluate the association between calcium intake, blood pressure levels and the laboratory tests. Multivariate regression models were performed to control potential confounders.Results: A significant increase of calcium intake during pregnancy was observed (931±301 mg/day to 1,195±467 mg/day, p<0.001. Plasma PTH-rp, endothelin, and nitrite-nitrate levels did not change during pregnancy. Among the women 38 (25.4% had low calcium intake (<800 mg/day with a larger increase of systolic and diastolic blood pressure during pregnancy (p=0.04 birth (p=0.006 and puerperium (p=0.01. After adjusting for other factors the multivariate analyses showed statistical association between low calcium intake, high parathormone levels and high systolic blood pressure levels during pregnancy (p=0.002.Conclusion: Low calcium intake during pregnancy is associated with a larger increase of systolic blood pressure and high parathormone levels.

Community problems have been associated with higher, and community resources and social cohesion with lower, blood pressure. However, prior studies have not accounted for potential confounding by residential racial segregation. This study tested associations between community characteristics and blood pressure levels and prevalent hypertension in a racially integrated community. The Exploring Health Disparities in Integrated Communities Study measured blood pressure in residents of two contiguous racially integrated and low-income US Census Tracts. Community characteristics included a standardized community problem score and binary indicators for community social cohesion, having a community leader available, and having at least one community resource observed on the participant's block. In adjusted models, greater community problems and proximity to resources were associated with lower systolic (β = -2.020, p = 0.028; β = -4.132, p = 0.010) and diastolic (β = -1.261, p = 0.038; β = -2.290, 0.031) blood pressure, respectively, among whites (n = 548). Social cohesion was associated with higher systolic (β = 4.905, p = 0.009) and diastolic blood pressure (β = 3.379, p = 0.008) among African Americans (n = 777). In one racially integrated low-income community, community characteristics were associated with blood pressure levels, and associations differed by race. Directions of associations for two findings differed from prior studies; greater community problem was associated with lower blood pressure in whites and community social cohesion was associated with higher blood pressure in African Americans. These findings may be due to exposure to adverse environmental conditions and hypertensive risk factors in this low-income community. PMID:25665523

The effect of fish consumption on blood pressure is controversial. The authors measured blood pressure and calculated oily fish servings per week in 677 community-dwellers aged 40 years and older living in rural coastal Ecuador. Using regression models with linear splines, the authors evaluated whether dietary fish intake was related to blood pressure levels, after adjusting for relevant confounders. Mean oily fish consumption was 9.1±5.6 servings per week. There was a nonlinear relationship between systolic pressure and fish servings. In the group of individuals consuming up to five servings per week, each serving significantly reduced systolic pressure by 2.3 mm Hg (P=.020). Any extra serving provided no further effects. The study shows an inverse relationship between oily fish consumption and systolic pressure. Currently recommended amounts of dietary oily fish intake per week (1-2 servings) might be insufficient to exert beneficial effects of fish in the control of blood pressure. PMID:26395549

Full Text Available The interactions of single nucleotide polymorphisms (SNPs and cigarette smoking on blood pressure levels are limited. The present study was undertaken to detect nine lipid-related SNPs and their interactions with cigarette smoking on blood pressure levels. Genotyping of ATP-binding cassette transporter A1 (ABCA-1 V825I, acyl-CoA:cholesterol acyltransferase-1 (ACAT-1 rs1044925, low density lipoprotein receptor (LDL-R AvaⅡ, hepatic lipase gene (LIPC -250G>A, endothelial lipase gene (LIPG 584C>T, methylenetetrahydrofolate reductase (MTHFR 677C>T, proprotein convertase subtilisin-like kexin type 9 (PCSK9 E670G, peroxisome proliferator-activated receptor delta (PPARD +294T>C, and Scavenger receptor class B type 1 (SCARB1 rs5888 was performed in 935 nonsmokers and 845 smokers. The interactions were detected by factorial regression analysis. The frequencies of genotypes (ACAT-1 and LIPG, alleles (ABCA-1, and both genotypes and alleles (LDL-R, LIPC, PPARD and SCARB1 were different between nonsmokers and smokers (P < 0.05-0.001. The levels of pulse pressure (PP, ABCA-1, and systolic, diastolic blood pressure (SBP, DBP and PP (LIPC in nonsmokers were different among the genotypes (P < 0.01-0.001. The levels of SBP (ABCA-1, ACAT-1, LIPG and PCSK9, DBP (ACAT-1, LDL-R, LIPC, PCSK9 and PPARD, and PP (LIPC, LIPG, MTHFR and PCSK9 in smokers were different among the genotypes (P < 0.01-0.001. The SNPs of ABCA-1, ACAT-1 and PCSK9; ACAT-1, LDL-R, MTHFR and PCSK9; and ABCA-1, LIPC, PCSK9 and PPARD were shown interactions with cigarette smoking to influence SBP, DBP and PP levels (P < 0.05-0.001; respectively. The differences in blood pressure levels between the nonsmokers and smokers might partly result from different interactions of several SNPs and cigarette smoking.
To measure serum leptin levels and compare them in lean and obese subjects and to identify correlation between serum leptin levels, heart rate and hypertension in lean and obese subjects among adult females. Seventy female subjects with different body mass indices were selected from OPD of Jinnah Medical and Dental College Hospital (OPD), Karachi. Heart rate was counted manually; blood pressure was measured by mercury sphygmomanometer while serum leptin was measured using enzyme-linked immunoassay. The outcomes hypertension and heart rate were correlated to risk factor leptin. Mean heart rate, systolic and diastolic blood pressure and serum leptin levels of obese people were 90+-1, 142+-2, 89+-1 and 24.13+-1.7 respectively, which were significantly higher as compared to lean subjects (p<0.05). All the parameters correlated positively and significantly with increasing BMI. There was a relationship of tachycardia and hypertension with high serum leptin levels in obesity. Serum leptin levels increase with the level of obesity. Hyper-leptinemia is associated with tachycardia and increases in both systolic and diastolic blood pressure in obesity via complex mechanisms.

Full Text Available BACKGROUND: Even with anti-hypertensive therapy, it is difficult to maintain optimal systemic blood pressure values in hypertensive patients. Exercise may reduce blood pressure in untreated hypertensive, but its effect when combined with long-term anti-hypertensive therapy remains unclear. Our purpose was to evaluate the acute effects of a single session of aerobic exercise on the blood pressure of long-term-treated hypertensive patients. METHODS: Fifty treated hypertensive patients (18/32 male/female; 46.5±8.2 years; Body mass index: 27.8±4.7 kg/m² were monitored for 24 h with respect to ambulatory (A blood pressure after an aerobic exercise session (post-exercise and a control period (control in random order. Aerobic exercise consisted of 40 minutes on a cycle-ergometer, with the mean exercise intensity at 60% of the patient's reserve heart rate. RESULTS: Post-exercise ambulatory blood pressure was reduced for 24 h systolic (126±8.6 vs. 123.1±8.7 mmHg, p=0.004 and diastolic blood pressure (81.9±8 vs. 79.8±8.5 mmHg, p=0.004, daytime diastolic blood pressure (85.5±8.5 vs. 83.9±8.8 mmHg, p=0.04, and nighttime S (116.8±9.9 vs. 112.5±9.2 mmHg, p<0.001 and diastolic blood pressure (73.5±8.8 vs. 70.1±8.4 mmHg, p<0.001. Post-exercise daytime systolic blood pressure also tended to be reduced (129.8±9.3 vs. 127.8±9.4 mmHg, p=0.06. These post-exercise decreases in ambulatory blood pressure increased the percentage of patients displaying normal 24h systolic blood pressure (58% vs. 76%, p=0.007, daytime systolic blood pressure (68% vs. 82%, p=0.02, and nighttime diastolic blood pressure (56% vs. 72%, p=0.02. Nighttime systolic blood pressure also tended to increase (58% vs. 80%, p=0.058. CONCLUSION: A single bout of aerobic exercise reduced 24h ambulatory blood pressure levels in long-term-treated hypertensive patients and increased the percentage of patients reaching normal ambulatory blood pressure values. These effects suggest that

Blood pressure is the force of blood against artery walls. It is measured in millimeters of mercury (mm Hg and recorded as two numbers: systolic pressure (as the heart contracts over diastolic pressure (as the heart relaxes between beats. High blood pressure (hypertension is defined as chronically elevated high blood pressure, with systolic blood pressure (SBP of 140 mm Hg or greater, and diastolic blood pressure (DBP of 90 mm Hg or greater. High blood pressure (HBP, smoking, abnormal blood lipid levels, obesity and diabetes are risk factors for coronary heart disease, the leading cause of death in the US. Lifestyle modifications such as engaging in regular physical activity, quitting smoking and eating a healthy diet (limiting intake of saturated fat and sodium and increasing consumption of fiber, fruits and vegetables are advocated for the prevention, treatment, and control of HBP. As multiple factors influence blood pressure, the effects of each factor are typically modest, particularly in normotensive subjects, yet the combined effects can be substantial. Nutrition plays an important role in influencing blood pressure. Orange juice should be included as part of any low sodium diet and/or any blood pressure reducing eating plan, as it is sodium free, fat-free and can help meet recommended levels of potassium intake that may contribute to lower BP.

Nesfatin is a peptide secreted by peripheral tissues, central and peripheral nervous system. It is involved in the regulation of homeostasis. Although the effects of nesfatin-1 on nutrition have been studied widely in the literature, the mechanisms of nesfatin-1 action and also relations with other physiological parameters are still not clarified well. We aimed to investigate the effect of peripheral chronic nesfatin-1 application on blood pressure regulation in normal and in rats exposed to restraint immobilization stress. In our study, three month-old male Wistar rats were used. Rats were divided into 4 groups as Control, Stress, Control+Nesfatin-1, Nesfatin-1+Stress. Angiotensinogen, angiotensin converting enzyme 2, angiotensin II, endothelin-1, endothelial nitric oxide synthase, aldosterone, cortisol, nesfatin-1 levels were determined in plasma samples by ELISA. Our results have shown that chronic peripheral nesfatin-1 administration increases blood pressure in normal and in rats exposed to chronic restraint stress. Effect of nesfatin-1 on circulating level of angiotensinogen, angiotensin converting enzyme 2, angiotensin II, endothelin-1, endothelial nitric oxide synthase, aldosterone and cortisol has been identified. We can conclude that elevated high blood pressure after chronic peripheral nesfatin-1 administration in rats exposed to chronic restraint stress may be related to decreased plasma level of endothelial nitric oxide synthase concentration.

The impact of fructose, commonly consumed with sugars by humans, on blood pressure and uric acid has yet to be defined. A total of 267 weight-stable participants drank sugar-sweetened milk every day for 10 weeks as part of their usual, mixed-nutrient diet. Groups 1 and 2 had 9% estimated caloric intake from fructose or glucose, respectively, added to milk. Groups 3 and 4 had 18% of estimated caloric intake from high fructose corn syrup or sucrose, respectively, added to the milk. Blood pressure and uric acid were determined prior to and after the 10-week intervention. There was no effect of sugar type on either blood pressure or uric acid (interaction P>.05), and a significant time effect for blood pressure was noted (Pfructose at the 50th percentile level, whether consumed as pure fructose or with fructose-glucose-containing sugars, does not promote hyperuricemia or increase blood pressure.

BackgroundIn a large collaborative study (n > 50,000), common variants in the natriuretic peptide (NP) genes were found to be associated with circulating NP levels and also with blood pressure (BP) levels based on office BP measurements (OBPMs). It is unknown if determining an individual's BP by 24......-h ambulatory BP measurements (ABPMs) will influence the effect of NP gene variations on BP levels.MethodsWe used rs632793 at the NPPB (NP precursor B) locus to investigate the relationship between genetically determined serum N-terminal pro-brain NP (NT-proBNP) concentrations and BP levels...... participants with the G:G genotype (geometric mean (95% confidence interval (CI)): 34.8 (31.5-38.4) pg/ml vs. 48.1 (41.9-55.3) pg/ml, P = 0.0002), but higher 24-h ambulatory BP levels (mean difference (95% CI): 2.0 (0.1-4.1) mm Hg, P = 0.043, for systolic BP and 1.7 (0.4-3.1) mm Hg, P = 0.011, for diastolic BP...

Blood pressure is the force of blood against artery walls. It is measured in millimeters of mercury (mm Hg) and recorded as two numbers: systolic pressure (as the heart contracts) over diastolic pressure (as the heart relaxes between beats). High blood pressure (hypertension) is defined as chronically elevated high blood pressure, with systolic blood pressure (SBP) of 140 mm Hg or greater, and diastolic blood pressure (DBP) of 90 mm Hg or greater. High blood pressure ...

Full Text Available Adherence to pharmacological treatment for hypertension is considered a key factor in guaranteeing successful therapy outcomes. Knowledge of the disease, its complications, as well as the need for changes in lifestyle, call for patient motivation and continuous interactive education. The evidence regarding the beneficial effects of changes in life style by hypertensive individuals in reducing the complications of the disease, as well as in its prevention are indisputable. However, the challenges posed by patient adherence to treatment prescribed by doctors remain. The aim of this study was to assess blood pressure levels together with degree of adherence to pharmacological treatment with Enalapril Maleate by means of the Morisky-Green Test, in hypertensive patients who were users of a School Pharmacy. Of the 102 patients interviewed, 65.7% had controlled blood pressure, but only 36.3% indicated total compliance with the pharmacological treatment. The Morisky-Green test proved ineffective in associating controlled blood pressure levels and positive attitudes toward taking antihypertensive medicines.A adesão ao tratamento farmacológico da hipertensão arterial sistêmica é considerada uma das etapas essenciais para a garantia do seu sucesso. Para tanto, o conhecimento da doença, suas complicações e necessidade de mudanças em relação ao estilo de vida, requer do paciente, além da motivação, a educação contínua e de modo compartilhado. A evidência quanto aos efeitos benéficos da mudança do estilo de vida pelo portador de hipertensão na redução das complicações desta doença, bem como em sua prevenção, já não são mais questionados, porém o desafio continua residindo na adesão do indivíduo ao padrão de tratamento prescrito pelo médico. Este estudo teve como objetivo avaliar os níveis de pressão arterial, assim como o nível de adesão ao tratamento farmacológico com maleato de enalapril de pacientes portadores de

The aim of this study was to describe the dietary patterns of pregnant women in northern Puerto Rico and explore associations between diet factors with pregnancy related measurements. This analysis is based on the Puerto Rico Testsite for Exploring Contamination Threats (PROTECT), a prospective cohort that is studying environmental risk factors for preterm births in PR. Participants completed a food frequency questionnaire (FFQ) around 20-28 weeks of gestation. The following pregnancy related measures were collected from the medical records: hemoglobin, blood glucose, blood pressure and gestational age. Potential associations between diet factors and pregnancy measures were assessed using chi square analysis with SPSS. A total of 180 participants completed the FFQ; low hemoglobin levels was found in 19.2%, high blood glucose levels was found in 21.1% by fasting blood glucose test and 24.6%by 1-hour 50 g oral glucose screening test, high blood pressure was found in 2.9% (systolic) and 6.5% (diastolic), and pre-term birth was found in 10.4% of the participants. High consumption of rice, desserts and sweets was associated with higher levels of fasting blood glucose levels (p desserts, can lead to high levels of blood glucose and can be a potential predictor of other pregnancy complications during pregnancy in these study participants, such as gestational diabetes.

Uric acid is associated with cardiovascular disease and cardiovascular disease risk factors in adults, including chronic kidney disease, coronary artery disease, stroke, diabetes mellitus, preeclampsia, and hypertension. We examined the association between uric acid and elevated blood pressure in a large, nationally representative cohort of US adolescents, a population with a relatively low prevalence of cardiovascular disease and cardiovascular disease risk factors. Among 6036 adolescents 12 to 17 years of age examined in the 1999-2006 National Health and Nutrition Examination Survey, the mean age was 14.5 years, 17% were obese (body mass index: ≥95th percentile), and 3.3% had elevated blood pressure. Mean serum uric acid level was 5.0 mg/dL, and 34% had a uric acid level ≥5.5 mg/dL. In analyses adjusted for age, sex, race/ethnicity, and body mass index percentile, the odds ratio of elevated blood pressure, defined as a systolic or diastolic blood pressure ≥95th percentile for age, sex, and height, for each 0.1-mg/dL increase in uric acid level was 1.38 (95% CI: 1.16-1.65). Compared with uric acid level ≥5.5 mg/dL had a 2.03 times higher odds of having elevated blood pressure (95% CI: 1.38-3.00). In conclusion, increasing levels of serum uric acid are associated with elevated blood pressure in healthy US adolescents. Additional prospective studies and clinical trials are needed to determine whether uric acid is merely a marker in a complex metabolic pathway or causal of hypertension and, thus, a potential screening and therapeutic target.

Full Text Available Poor eating habits may represent cardiovascular risk factors since high intake of fat and saturated fatty acids contributes to dyslipidemia, obesity, diabetes mellitus, and hypertension. Thus, nutritional interventions are recognized as important strategies for primary prevention of hypertension and as adjuvants to pharmacological therapies to reduce cardiovascular risk. The DASH (Dietary Approach to Stop Hypertension plan is one of the most effective strategies for the prevention and nonpharmacological management of hypertension. The beneficial effects of DASH diet on blood pressure might be related to the high inorganic nitrate content of some food products included in this meal plan. The beetroot and other food plants considered as nitrate sources account for approximately 60–80% of the daily nitrate exposure in the western population. The increased levels of nitrite by nitrate intake seem to have beneficial effects in many of the physiological and clinical settings. Several clinical trials are being conducted to determine the broad therapeutic potential of increasing the bioavailability of nitrite in human health and disease, including studies related to vascular aging. In conclusion, the dietary inorganic nitrate seems to represent a promising complementary therapy to support hypertension treatment with benefits for cardiovascular health.

UNLABELLED: The genetics of hypertension has been scrutinized in large-scale genome-wide association studies (GWAS) with a large number of common genetic variants identified, each exerting subtle effects on disease susceptibility. An amino acid polymorphism, p.Arg82Cys, in CD300LG was recently fo...... found to be associated with fasting HDL-cholesterol and triglyceride levels. The polymorphism has not been detected in hypertension GWAS potentially due to its low frequency, but CD300LG has been linked to blood pressure as CD300LG knockout mice have changes in blood pressure. Twenty...... (122 mmHg versus 115; p = 0.01) and diastolic blood pressure (77 mmHg versus 72; p<0.01) compared with CC-carriers. There were no differences in CIMT between the two groups.

Background Controlling hypertension rates and maintaining normal blood pressure, particularly in resource-constrained settings, represent ongoing challenges of effective and affordable implementation in health care. One of the strategies being largely advocated to improve high blood pressure calls for salt reduction strategies. This study aims to estimate the impact of a population-level intervention based on sodium reduction and potassium increase – in practice, introducing a low-sodium, high-potassium salt substitute – on adult blood pressure levels. Methods/Design The proposed implementation research study includes two components: Phase 1, an exploratory component, and Phase 2, an intervention component. The exploratory component involves a triangle taste test and a formative research study designed to gain an understanding of the best implementation methods. Phase 2 involves a pragmatic stepped wedge trial design where the intervention will be progressively implemented in several clusters starting the intervention randomly at different times. In addition, we will evaluate the implementation strategy using a cost-effectiveness analysis. Discussion This is the first project in a Latin-American setting to implement a salt substitution intervention at the population level to tackle high blood pressure. Data generated and lessons learnt from this study will provide a strong platform to address potential interventions applicable to other similar low- and middle-income settings. Trial registration This study is registered in ClinicalTrials.gov NCT01960972. PMID:24667035
Full Text Available Abstract Background Systolic blood pressure (SBP decline has been reported in octogenarians. The aim was to study if it could be observed while measuring SBP with two methods: Korotkoff (K-BP and Strain-Gauge-Finger-Pletysmography (SG-BP, and which of them were more reliable in expressing vascular burden. Methods A cohort of 703 men from a population of Malmö, Sweden, were included in "Men born in 1914-study" and followed-up at ages: 68 and 81 years. 176 survivors were examined with K-BP and SG-BP at both ages, and 104 of them with Ambulatory Blood Pressure at age 81/82. Ankle Brachial Index (ABI was measured on both occasions, and Carotid Ultrasound at age 81. Results From age 68 to 81, mean K-BP decreased in the cohort with mean 8.3 mmHg, while SG-BP increased with 13.4 mmHg. K-BP decreased in 55% and SG-BP in 31% of the subjects. At age 81, K-BP was lower than SG-BP in 72% of subjects, and correlated to high K-BP at age 68 (r = --.22; p Conclusion In contrast to K-BP, values of SG-BP in octogenarians strongly correlated with Ambulatory Blood Pressure. The SG-BP decline in the last decade was rare, and increasing SG-BP better than K-BP reflected advanced atherosclerosis. It should be aware, that K-BP underdetected 46% of subjects with SG-BP equal/higher than 140 mmHg at age 81, which may lead to biased associations with risk factors due to differential misclassification by age.

Full Text Available Abstract Background We aimed to investigate if overweight and obese adults "close" to Mediterranean diet present better insulin, lipids profile and better pressure levels, compared to individuals close to a more Westernized diet. Methods The ATTICA study is a population-based cohort that has randomly enrolled 3042 adult men and women, stratified by age – gender, from the greater area of Athens, during 2001–2002. Of them, in this work were have studied 1762 participants with excess body weight, meaning overweight (BMI: 25–29.9 kg/m2 and obese (BMI>30 kg/m2. 1064 were men and 698 women (20–89 years old. Adherence to Mediterranean diet was assessed through a diet-score that was based on a validated food-frequency questionnaire. Blood pressure was measured and also fasting glucose, insulin and blood lipids. Insulin sensitivity was also assessed by the homeostasis model assessment (HOMA approach (glucose × insulin/22.5. Results Individuals with excess bodyweight in the highest tertile of diet score, were more insulin sensitive than those in the lowest tertile (11.4% lower HOMA, p = 0.06, had 13% lower levels of total cholesterol (p = 0.001 and 3 mmHg decrease of systolic blood pressure levels (p Conclusion Adherence to Mediterranean diet is modeslty associated with a better insulin sensitivity, lower levels of total cholesterol and lower levels of systolic blood pressure in overweight and obese subjects. This may suggest that compared to general population, the beneficial effect of this diet in cardiovascular system of excess body weight people is limited.

Serum cortisol and total protein levels, blood pressure, heart rate, lung volume, and reaction time were studied in 52 males 20-25 years of age practicing Dhammakaya Buddhist meditation, and in 30 males of the same age group not practicing meditation. It was found that after meditation, serum cortisol levels were significantly reduced, serum total protein level significantly increased, and systolic pressure, diastolic pressure and pulse rate significantly reduced. Vital capacity, tidal volume and maximal voluntary ventilation were significantly lower after meditation than before. There were also significant decreases in reaction time after mediation practice. The percentage decrease in reaction time during meditation was 22%, while in subjects untrained in meditation, the percentage decrease was only 7%. Results from these studies indicate that practising Dhammakaya Buddhist meditation produces biochemical and physiological changes and reduces the reaction time. PMID:1801007

Full Text Available Plasma amyloid beta (Aβ levels are being investigated as potential biomarkers for Alzheimer's disease. In AB128 cross-sectional study, a number of medical relevant correlates of blood Aβ40 or Aβ42 were analyzed in 140 subjects (51 Alzheimer's disease patients, 53 healthy controls and 36 individuals diagnosed with mild cognitive impairment. We determined the association between multiple variables with Aβ40 and Aβ42 levels measured in three different blood compartments called i Aβ directly accessible (DA in the plasma, ii Aβ recovered from the plasma matrix (RP after diluting the plasma sample in a formulated buffer, and iii associated with the remaining cellular pellet (CP. We confirmed that diastolic blood pressure (DBP is consistently correlated with blood DA Aβ40 levels (r=-0.19, P=0.032. These results were consistent in the three phenotypic groups studied. Importantly, the observation resisted covariation with age, gender or creatinine levels. Observed effect size and direction of Aβ40 levels/DBP correlation are in accordance with previous reports. Of note, DA Aβ40 and the RP Aβ40 were also strongly associated with creatinine levels (r=0.599, P<<0.001 and to a lesser extent to urea, age, hematocrit, uric acid and homocysteine (p<0.001. DBP and the rest of statistical significant correlates identified should be considered as potential confounder factors in studies investigating blood Aβ levels as potential AD biomarker. Remarkably, the factors affecting Aβ levels in plasma (DA, RP and blood cell compartments (CP seem completely different.

Full Text Available Few studies have examined Japanese with regard to the achievement rates for target blood pressure levels, or the relationship between these rates and healthy lifestyle characteristics in patients with hypertension as defined by the newly established hypertension management guidelines (JSH2014. The aim of this study was to elucidate achievement rates and examine healthy lifestyle characteristics associated with achievement status among Japanese.This cross-sectional study, conducted in January-December 2012, examined blood pressure control and healthy lifestyle characteristics in 8,001 Japanese workers with hypertension (mean age, 57.0 years; 78.8% were men who participated in a workplace health checkup. Data were collected from workplace medical checkup records and participants' self-administered questionnaires. We divided into 5 groups [G1; young, middle-aged, and early-phase elderly patients (65-74 years old without diabetes mellitus or chronic kidney disease (CKD (<140/90 mmHg, G2; late-phase elderly patients (≥75 years old without diabetes mellitus or CKD (<150/90 mmHg, G3; diabetic patients (<130/80 mmHg, G4; patients with CKD (<130/80 mmHg, and G5; patients with cerebrovascular and/or coronary artery diseases (<140/90 mmHg] according to JSH2014. And then, achievement rates were calculated in each group. Multivariate analysis identified healthy lifestyle characteristics associated with "therapeutic failure" of target blood pressure.Target blood pressures were achieved by 60.2% of young, middle-aged, and early-phase elderly patients (G1, 71.4% of late-phase elderly patients (G2, 30.5% of diabetic patients (G3, 33.4% of those with chronic kidney disease (G4, and 66.0% of those with cerebrovascular and/or coronary artery diseases (G5. A body mass index of 18.5-24.9 and non-daily alcohol consumption were protective factors, and adequate sleep was found to contribute to therapeutic success.We found low achievement rates for treatment goals

Full Text Available The aim of this study was to analyze the thickness of the intima-media complex (IMC using a noninvasive method. The carotid and femoral common arteries were evaluated by noninvasive B-mode ultrasound in 63 normotensive and in 52 hypertensive subjects and the thickness of the IMC was tested for correlation with blood pressure, cardiac structures and several clinical and biological parameters. The IMC was thicker in hypertensive than in normotensive subjects (0.67 ± 0.13 and 0.62 ± 0.16 vs 0.54 ± 0.09 and 0.52 ± 0.11 mm, respectively, P<0.0001. In normotensive patients, the simple linear regression showed significant correlations between IMC and age, body mass index and 24-h systolic blood pressure for both the carotid and femoral arteries. In hypertensives the carotid IMC was correlated with age and 24-h systolic blood pressure while femoral IMC was correlated only with 24-h diastolic blood pressure. Forward stepwise regression showed that age, body mass index and 24-h systolic blood pressure influenced the carotid IMC relationship (r2 = 0.39 in normotensives. On the other hand, the femoral IMC relationship was influenced by 24-h systolic blood pressure and age (r2 = 0.40. In hypertensives, age and 24-h systolic blood pressure were the most important determinants of carotid IMC (r2 = 0.37, while femoral IMC was influenced only by 24-h diastolic blood pressure (r2 = 0.10. There was an association between carotid IMC and echocardiographic findings in normotensives, while in hypertensives only the left posterior wall and interventricular septum were associated with femoral IMC. We conclude that age and blood pressure influence the intima-media thickness, while echocardiographic changes are associated with the IMC.

Blood pressure measurement is the cornerstone for the diagnosis, the treatment and the research on arterial hypertension, and all of the decisions about one of these single aspects may be dramatically influenced by the accuracy of the measurement. Over the past 20 years or so, the accuracy of the conventional Riva-Rocci/Korotkoff technique of blood pressure measurement has been questioned and efforts have been made to improve the technique with automated devices. In the same period, recognition of the phenomenon of white coat hypertension, whereby some individuals with an apparent increase in blood pressure have normal, or reduced, blood pressures when measurement is repeated away from the medical environment, has focused attention on methods of measurement that provide profiles of blood pressure behavior rather than relying on isolated measurements under circumstances that may in themselves influence the level of blood pressure recorded. These methodologies have included repeated measurements of blood pressure using the traditional technique, self-measurement of blood pressure in the home or work place, and ambulatory blood pressure measurement using innovative automated devices. The purpose of this review to serve as a source of practical information about the commonly used methods for blood pressure measurement: the traditional Riva-Rocci method and the automated methods.

Background: Normal kidney function is regulated by Nitric oxide (NO) and Superoxide (O/sub 2/-) in the body, and consequently controls blood pressure. Nitric Oxide promotes natriuresis and diuresis, and therefore results in reduction of blood pressure. The objective of this study was to determine the effect of L-arginine supplementation on blood pressure, urinary protein, nitrite and nitrate in addition to blood urea, serum creatinine and creatinine clearance in uremic rabbits. Methods: This study was carried out in the Department of Biochemistry Basic Medical Sciences Institute, Jinnah Postgraduate Medical Centre, Karachi. A total of 48 rabbits were included in the study. Twenty-four of the rabbits on surgical intervention were prepared as uremic and so became hypertensive as well. Two groups were uremic, one group was given L-arginine and the other was remained untreated. Systolic and diastolic blood pressure was measured on week 0, week 2, week 4, and week 6, while blood and urine was collected on week 0 and week 6. Results: On supplementation with L-arginine to uremic rabbits systolic and diastolic blood pressures were decreased significantly. Nitrite/nitrate and urinary protein were corrected to some extent while blood urea and serum creatinine were unaffected. Conclusion: L-arginine has a beneficial role as blood pressure lowering agent in uremic rabbits. It corrects NO/sub 2/NO/sub 3/ plasma level and proteinuria which is indicator of renal failure.

Full Text Available Background: Ethanolic extract of licorice root has been shown to reduce low-density lipoprotein (LDL oxidation in atherosclerotic mice and in both hypercholesterolemic and normal lipidemic humans. Objective: This study examined the effect of licorice-root extract on carotid intima-media thickness (CIMT in individuals with hypercholesterolemia. Design: Individuals with hypercholesterolemia (total cholesterol ≥6.18 mmol/L [240 mg/dL] and without significant stenosis were randomly allocated to two groups: an experimental group that consumed 0.2 g/day of ethanolic extract of licorice root for 12 months, and a control group that received a placebo. Results: Of 110 eligible participants, 94 (41–80 years old completed the study. A significant CIMT decrease from 0.92±0.25 mm to 0.84±0.21 mm was observed in the experimental group compared with an increase from 0.85±0.17 mm to 0.88±0.19 mm in the control group. Mean plasma total cholesterol levels and LDL cholesterol decreased, at the range baseline to 1 year, from 284±32 mg/dl to 262±25 mg/dl and from 183±8.5 mg/dl to 174±9.1 mg/dl, respectively, for the experimental group (p<0.001 and from 291±35 to 289±31 mg/dl and from 177.6±10.7 to 179.3±9.6 (p=0.08, respectively, for the control group. Mean high-density lipoprotein (HDL did not change significantly in either group. In the experimental group, systolic blood pressure decreased from 138±12 mmHg to 125±13 mmHg after 1 year (p=0.01 and increased from 136±15 mmHg to 137±13 mmHg in the control group. Diastolic blood pressure decreased from 92±9 mmHg to 84±10 mmHg (p=0.01 in the experimental group and increased from 89±11 mmHg to 90±8 mmHg in the control group. Conclusion: Following 1 year of licorice consumption, mean CIMT, total cholesterol, LDL levels, and blood pressure were decreased. This suggests that licorice may attenuate the development of atherosclerosis and of related cardiovascular diseases.

Arterial hypertension is associated with an increased risk of atrial fibrillation (AF), and leads to a pronounced increase in morbidity and mortality. Left atrial volume (LAV) is an important prognostic marker in the older populations. The aim of our study was to identify the clinical and echocardiographic determinants of LAV in middle-aged (<70 years old) essential hypertensive patients.We evaluated cardiac structure and function in 458 patients, 394 treated and untreated mild to moderate essential hypertensives patients (mean+/-s.d. age 48.4+/-11.1 years) with no associated clinical condition and 64 normotensive control participants (age 45.7+/-12.8 years; P=0.12). A multivariate analysis was performed to calculate the relative weight of each of the variables considered able to predict LAV. The LAV index (LAVi) was significantly increased in the essential hypertensive group vs the control group and was significantly dependent on blood pressure levels (SBP and DBP, P<0.05 for both) and body mass index (BMI) (P<0.0001). Considering the left ventricular (LV) variables, the LV mass index (LVMI) (R(2)=0.19, P<0.001) and LAV were increased in essential hypertensive patients with left ventricular hypertrophy (LVH), and patients with enlarged LAV showed lower systolic and diastolic function and an increased LVMI. The LAVi is dependent on blood pressure levels and anthropometric variables (age and BMI). Further structural (LVMI) and functional (systolic and diastolic) variables are related to the LAVi; LVMI is the most important variable associated with LAV in mild to moderate essential hypertensive adult patients. These findings highlight the importance of left atrium evaluation in adult, relatively young, essential hypertensive patients. PMID:19262581

Full Text Available Mahsa Mohammadi1, Inger Ekman2, Maria Schaufelberger31Department of Medicine; 2Institute of Health and Care Sciences; 3Departments of Emergency and Cardiovascular Medicine, The Sahlgrenska Academy at Goteborg University, Goteborg, Sweden.Objective: To investigate whether change in objective signs during up-titration of angiotensin-converting enzyme (ACE-inhibitors in patients with chronic heart failure affect perception of information about medicines and subjective activities such as self-care.Methods: Consecutive patients referred for up-titration of ACE-inhibitors were included. Patients were given the Satisfaction with Information about Medicines Scale and the European Heart Failure Self-Care Behaviour Scale at their first visit and when the target dose was reached. Blood pressure, pulse and s-creatinine were measured at each visit.Results: Relationships were found between change in systolic (r = 0.224, p = 0.044 and diastolic (r = 0.361, p = 0.001 blood pressure and change in self-care scores and were also observed at baseline (r = 0.324, 0.398, p = 0.001, 0.000 and follow-up (r = 0.317, 0.253, p = 0.004, 0.022. Diastolic blood pressure correlated with the “potential problem of medication” score (r = −0.263, p = 0.007.Conclusion: Patients with a more advanced disease usually have a lower blood pressure. Hence, the relationship between blood pressure and self-care scores might indicate that patients are more motivated to adhere to prescriptions the more advanced the stage of their disease.Keywords: blood pressure, chronic heart failure, adherence, scales

It is very important to maintain the level of mean arterial pressure (MAP).The MAP control is applied in many clinical situations,including limiting bleeding during cardiac surgery and promoting healing for patient's post-surgery.This paper presents a fuzzy controller-based multiple-model adaptive control system for postoperative blood pressure management.Multiple-model adaptive control (MMAC) algorithm is used to identify the patient model,and it is a feasible system identification method even in the presence of large noise.Fuzzy control (FC) method is used to design controller bank.Each fuzzy controller in the controller bank is in fact a nonlinear proportional-integral (PI) controller,whose proportional gain and integral gain are adjusted continuously according to error and rate of change of error of the plant output,resulting in better dynamic and stable control performance than the regular PI controller,especially when a nonlinear process is involved.For demonstration,a nonlinear,pulsatile-flow patient model is used for simulation,and the results show that the adaptive control system can effectively handle the changes in patient's dynamics and provide satisfactory performance in regulation of blood pressure of hypertension patients.

Full Text Available Better understanding is needed for antihypertensive medication initiation and lifestyle modification among younger populations with elevated blood pressure. This study aimed to assess health behavior change after receiving a report of elevated blood pressure among African Americans and Caucasians younger than 50 years old. We used the Coronary Artery Risk Development in Young Adults (CARDIA repository dataset. By examination year twenty, 424 out of 2,478 Caucasian and 2,637 African American participants had received feedback from the CARDIA study due to elevated blood pressure readings. Blood pressure was measured by trained CARDIA researchers at the participant's home and was repeatedly recorded at seven examinations over twenty years. A feedback/referral letter was sent to participants with an elevated blood pressure reading. On average, participants first had an elevated blood pressure reading at the age of 34. After receiving the feedback letter, 44% of the previously undiagnosed participants received a formal diagnosis. In addition, 23% initiated the use of antihypertensive medication if they had not received medication treatment before. Among the participants with at-risk lifestyle behaviors, 40% reduced alcohol consumption, 14% increased exercise level, 11% stopped smoking, and 8% reached normal weight. While none of the studied patient factors were associated with lifestyle modification, age had a positive impact on antihypertensive medication initiation (p<0.05. We found no evidence of differences in health behavior change between African American and Caucasian participants after receiving the feedback letter.

Objective: To observe the effect of acupuncture of Fengchi (风池 GB 20) on blood pressure,serum IL-6 and plasma endothelin (ET) contents in patients with hypertension. Methods: Thirty cases of hypertension patients were made up of treatment group and treated with acupuncture of Fengchi (GB 20); while 20 healthy subjects were made up of control group. Blood pressure was determined before and after the treatment. Fasting blood samples were taken from the cubital venous vessel for detecting serum interleukin (IL)-6 and plasma ET contents with radioimmunoassay before and after acupuncture treatment. Results: Before the treatment, in hypertension patients, serum IL-6 and plasma ET levels were significant higher than those in healthy subjects (P ＜ 0.01 ); while after the treatment, blood pressure of treatment group declined significantly ( P ＜ 0.01 ), serum IL-6 and plasma ET levels decreased considerably ( P ＜ 0.01 ). Conclusion:Acupuncture of Fengchi (GB 20) can lower blood pressure, regulate cellular immunity and secretion functions of the vascular endothelial cells in hypertension patients.

The advent of ambulatory blood pressure monitoring permitted examination of blood pressures during sleep and recognition of the associated circadian fall in pressure during this period. The fall in pressure,called the "dip",is defined as the difference between daytime mean systolic pressure and nighttime mean systolic pressure expressed as a percentage of the day value. Ten percent to 20% is considered normal. Dips less than 10%,referred to as blunted or absent,have been considered as predicting an adverse cardiovascular event. This view and the broader concept that white coat hypertension itself is a forerunner of essential hypertension is disputable. This editorial questions whether mean arterial pressures over many hours accurately represent the systolic load,whether nighttime dipping varies from measure to measure or is a fixed phenomenon,whether the abrupt morning pressure rise is a risk factor or whether none of these issues are as important as the actual night time systolic blood pressure itself. The paper discusses the difference between medicated and nonmedicated white coat hypertensives in regard to the cardiovascular risk and suggests that further work is necessary to consider whether the quality and duration of sleep are important factors.

Mean arterial pressure (MAP) is surprisingly similar across different species of mammals, and it is, in general, not known which factors determine the arterial pressure level. Mammals often have a pronounced capacity for sustained physical performance. This capacity depends on the vasculature having a flow reserve that comes into play as tissue metabolism increases. We hypothesize that microvascular properties allowing for a large vascular flow reserve is linked to the level of the arterial pressure.To study the interaction between network properties and network inlet pressure, we developed a generic and parsimonious computational model of a bifurcating microvascular network where diameter and growth of each vessel evolves in response to changes in biomechanical stresses. During a simulation, the network develops well-defined arterial and venous vessel characteristics. A change in endothelial function producing a high precapillary resistance and thus a high vascular flow reserve is associated with an increase in network inlet pressure. Assuming that network properties are independent of body mass, and that inlet pressure of the microvascular network is a proxy for arterial pressure, the study provides a conceptual explanation of why high performing animals tend to have a high MAP.

Traditional Thai massage (TTM) has been applied widely to promote relaxation. However, there is little evidence to support its efficacy on academic stress. A randomised controlled trial was performed to examine the acute effects of TTM on cortisol level, blood pressure, heart rate and stress perception in academic stress. This prospective trial included 36 physiotherapy students with a self perceived stress score of between 3 and 5. They were randomly allocated into the TTM (18 people) group or the control group (18 people). Saliva cortisol level, blood pressure, heart rate and stress perception rating were measured before and after the intervention. Both groups showed a significant reduction in cortisol level and heart rate when compared with baseline (p < 0.001). There were no significant differences in cortisol level between the two groups. The results suggest the need for further study into other possible physiological effects on stress of TTM. PMID:27210845

Left ventricular hypertrophy (LVH) is considered an independent risk factor even in the absence of systemic hypertension. Electrocardiographic (ECG) LVH with repolarisation changes has been found in some countries to carry more coronary risk than LVH alone. How far this observation is true among adult Nigerians is not known. We therefore decided to study adult Nigerians with ECG-LVH with or without ST-T waves changes and compare them with normal age matched controls (without ECG-LVH) in relation with established modifiable risk factors such as systemic hypertension (BP), body mass index (BMI), fasting blood sugar (FBS) and serum lipids such as total cholesterol (Tc), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and triglyceride (TG). Adult Nigerians who were consecutively referred to the ECG laboratory were randomly recruited. Three hundred patients were studied. Their blood pressures (BP) as well as body mass indices were recorded after recording their resting 12 read ECG using portable Seward 9953 ECG machine. Their waist-hip ratio (WHR) was also recorded. Blood samples were taken to determine their fasting blood sugar and serum lipids. Their ECG tracings were read by the cardiologists involved in the study while the blood samples were analysed by the chemical pathologist also involved in the study. At the end of the ECG reading, the patients were divided into 3 groups according to whether there was no ECG-LVH (control group A), ECG-LVH alone (group B), and ECG-LVH with ST-T waves changes (group C). One hundred and fifty (50%) patients belonged to group A, 100 (33.3%) patients to group B and 50 (16.7%) group C. Group B patients were found to have higher modifiable risk factors in form of systemic BP. Tc, LDL-C, and WHR compared to group A. However, the group C patients had increased load of these coronary risk factors in terms of BP elevation, higher BMI, FBS, and scrum cholesterol compared to group B. In addition

Full Text Available IntroductionPolicy, environmental, and systems-level interventions are part of a comprehensive approach to managing high blood pressure and high cholesterol, which are key risk factors for heart disease and stroke. In this qualitative case study, we identified clinical practices in health care organizations that used policy, environmental, or systems-level interventions to improve patient outcomes for these conditions. Our 4 objectives were to describe 1 policy, environmental, and systems-level interventions; 2 enabling factors and barriers that affected implementation; 3 methods for evaluating the success of the intervention; and 4 lessons learned from the health care practices that implemented these interventions.MethodsThrough literature review and expert guidance, we identified 34 health care practices that used policy, environmental, and systems-level interventions to manage high blood pressure and high cholesterol. In 2003, we conducted case study interviews with key informants for 9 health care practices that 1 demonstrated improved patient outcomes for blood pressure or cholesterol; 2 implemented the interventions for at least 1 year; and 3 remained committed to sustaining or institutionalizing interventions. We taped and transcribed the interviews and used Centers for Disease Control and Prevention EZ-Text software (www.cdc.gov/hiv/software/ez-text.htm to code, categorize, and analyze the responses.ResultsThe health care practices we studied implemented specialized lipid clinics, disease management programs, physician reminder systems, and participation in the Health Resources and Services Administration’s Bureau of Primary Care Health Disparities Collaboratives. All practices used comprehensive systems for patient care that were well-defined, measurable, and linked to desirable patient outcomes. Most relied on data systems to identify patients targeted for the interventions and practice areas that needed improvement, and to track the

The aim of this study was to analyze whether systolic blood pressure (SBP), heart rate (HR) and rate pressure product (RPP) during exercise in childhood can predict resting SBP levels in adolescence independent of resting SBP and conventional cardiovascular risk factors. We studied this in a sample of Danish children followed longitudinally for 6 years. The study comprised 226 children randomly sampled at age 9, who had their blood pressure and HR measured during ergometer exercise to exhaustion and was reassessed in adolescence. SBP and RPP during exercise in stage two of the test were positively associated with future resting SBP, independent of resting SBP in childhood (P=0.045 and P=0.013, respectively). After additional adjustment for conventional cardiovascular risk factors the associations with SBP and RPP during stage two on future resting SBP only slightly materially change, although only RPP remained significant (P=0.059 and P=0.012, respectively). No significant independent associations were observed for HR during exercise, but associations were in the same direction. Our results supports that measuring SBP and RPP, during a standard acute ergometer exercise test in children, improves the prediction of future SBP levels during rest in adolescence independent of resting SBP and conventional cardiovascular risk factors.

Full Text Available Primary open angle glaucoma affects more than 67 million people. Elevated intraocular pressure (IOP is a risk factor for glaucoma and may reduce nutrient availability by decreasing ocular perfusion pressure (OPP.

Here we sought to determine how acute modifications of arterial pressure will affect the susceptibility of neuronal function and blood flow to IOP challenge. Anaesthetized (ketamine:xylazine Long-Evan rats with low (∼60 mmHg, sodium nitroprusside infusion, moderate (∼100 mmHg, saline, or high levels (∼160 mmHg, angiotensin II of mean arterial pressure (MAP, n = 5-10 per group were subjected to IOP challenge (10-120 mmHg, 5 mmHg steps every 3 minutes. Electroretinograms were measured at each IOP step to assess bipolar cell (b-wave and inner retinal function (scotopic threshold response or STR. Ocular blood flow was measured using laser-Doppler flowmetry in groups with similar MAP level and the same IOP challenge protocol. Both b-wave and STR amplitudes decreased with IOP elevation. Retinal function was less susceptible to IOP challenge when MAP was high, whereas the converse was true for low MAP. Consistent with the effects on retinal function, higher IOP was needed to attenuated ocular blood flow in animals with higher MAP. The susceptibility of retinal function to IOP challenge can be ameliorated by acute high BP, and exacerbated by low BP. This is partially mediated by modifications in ocular blood flow.

Case of diabetes mellitus associated with essential hypertension are mostly type 2 diabetes mellitus(NIDDM) in elderly patients. In the JNC VI and JSH 2004, it is recommended that the therapeutic target blood pressure level should be lower then 130/80 mmHg in hypertension complicated with diabetes mellitus, and this target has recently obtained wide acceptance. On the other hand, the target blood pressure in elderly is recommended below 140/90 mmHg. Accordingly, diabetes mellitus in elderly hypertensives should be treated similarly as in the young and middle-aged. Because ACE inhibitors/ARBs or Ca blockers increase insulin sensitivity, these drugs should be used as the first choice in cases of elderly hypertensive patients complicated with diabetes mellitus.

In this thesis we have explored different aspects of blood pressure measurement and related it to the risk of cardiovascular disease. In the first part we showed that when the arm is positioned under heart level, for example when the arm is placed on a desk or a chair support, the blood pressure and the cardiovascular risk is overstimated. We demonstrated that crossing the legs at the level of the knee, but not at the level of the ankle, causes a rise of blood pressure. We proved that the phy...
Full Text Available The article is devoted to the study of systolic blood pressure features in the population of large industrial center. On the basis of measurement of blood pressure in adult population of three city regions there were revealed the following age-related changes in systolic blood pressure in men: three periods of rise and two periods of stabilization. The principal difference in women is the absence of the periods of rise and stabilization, lower level of blood pressure in young and middle aged people and authentically higher level of blood pressure - in elderly women. The increase of haemodynamical loading for one year of life in men of the middle (2 times and elder ages (3 times was revealed, that was not typical forwomen.

Indirect arterial blood pressure measurement has not changed substantially since its introduction by Riva-Rocci in 1986, Korotkoff in 1905 and Recklinghausen in 1906. Random measurements in the clinic or practice reflect only incompletely the dynamic nature of the blood pressure. Blood pressure recordings by patients themselves have provided more information through better temporal resolution, however, exact characterization of the pressure response throughout the entire day and, in particular, during physical exertion are not enabled; the latter are especially important with regard to diagnosis and treatment of hypertension. In 1966, therefore, radiotelemetric transmission of direct, continuously-measured arterial blood pressure was developed which enabled beat-to-beat registration of blood pressure, outside the laboratory, during normal daily life and sport activities. The initial results showed a marked variability of the blood pressure during the course of the day (Figure 1). Excessive blood pressure increases were observed during exposure to cold, static and dynamic exercise and to a lesser degree during automobile driving and exposure to heat (Figure 3). Recording of the pressure curves via transmission by radiotelemetry shows a high degree of accuracy and temporal resolution, spatial and situational freedom but is invasive and costly in terms of personnel. The same holds true for direct continuous blood pressure registration and storage on a portable tape recorder. Portable, automatic blood pressure measuring units for ambulatory monitoring employ indirect auscultatory or oscillometric recording with a cuff. As compared with the radiotelemetric direct continuous blood pressure measuring method, the indirect method has subordinate temporal resolution, that is, the measurements are only intermittent.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2676813

A high blood pressure level in adults is considered the single most important modifiable risk factor for global disease burden, especially those of cardiovascular (CV) origin such as stroke and ischemic heart disease. Because blood pressure levels have been shown to persist from childhood to adulthood, elevations in pediatric levels have been hypothesized to lead to increased CV burden in adulthood and, as such, might provide a window in the life course where primordial and primary prevention...

Fourteen patients with high normal (main group) and 15 subjects with optimal (control group) blood pressure (BP) were examined. Fasting and postprandial (60 and 120 min after oral intake of glucose) levels of glucose, insulin, interleukin (IL)-1β, tumor necrosis factor (TNF)-α, and C-reactive protein were measured. At the same time spectral analysis of heart rate variability (HRV) was done. Body mass index (BMI) and insulin resistance index (as HOMA-IR) were calculated. In patients with high normal BP total power of HRV was decreased (p glucose loading were blunted. In persons with optimal BP transient elevation of low frequency component and low/high ratio in 60 min after onset of glucose tolerance test (GTT) were registered; values of both parameters were higher than in the main group (p control group were accompanied by transient elevations of levels of inflammatory cytokines: IL-10 and TNF-α in 60 min, IL-6 in 120 min after GTT onset (p glucose level 60 min after glucose intake were higher in patients from the main group (p optimal and high normal BP have different variants of vegetative nervous system reactions to pulsatile hyperglycemia which is accompanied by changes of levels of inflammatory cytokines and worsening of carbohydrate metabolism in patients with high normal BP.

Results. PWPV values were found to correlate with age, functional class of RA, risk level by the Framingham model, ventricular septal thickness, left ventricular relative wall thickness, erythrocyte sedimentation rate, and the presence of C-reactive protein. After one-year follow-up, the diminished elasticity of vessels correlated with the baseline duration of morning stiffness, the number of swollen joints, and ineffective therapy for RA. The RA patients in whom BP increased to the upper normal range or who developed essential hypertension (EH had significantly higher values of vascular wall rigidity at the beginning of the follow-up. BP elevation was also associated with age, baseline clinical activity, the systemic manifestations of RA, the cardiovascular risk by the Framingham model. There was an association of vascular elastic properties in RA patients with the magnitude and uncontrolled activity of inflammation and with elevated BP. Conclusion. The findings show it important to reduce the elastic properties of vessels in the emergence of EH in RA.

Full Text Available Obesity, insulin resistance (IR, inflammation, and hyperandrogenism may lead to polycystic ovary syndrome (PCOS and hypertension. Nesfatin-1 (N1 may be related to IR, obesity, and hypertension. Furthermore, a vitamin D (VD deficiency is associated with hypertension and PCOS. We aimed to investigate N1 and VD levels in PCOS that have an effect on systolic and diastolic blood pressure (BP and heart rate (HR.This study included 54 patients with PCOS and 48 age-body mass index (BMI-matched healthy controls. PCOS was diagnosed according to clinical practice guidelines. Ferriman-Gallwey scores (FGS were calculated, while N1, VD, and other hormonal and biochemical parameters were measured for all subjects. Systolic and diastolic BP was measured as well. HR was calculated using an electrocardiogram.The levels of N1 (p < 0.001, high-sensitivity C-reactive protein (hs-CRP (p = 0.036, homeostasis model assessment as an index of insulin resistance (HOMA-IR (p < 0.001, systolic (p < 0.001 and diastolic (p < 0.001 BP and HR (p < 0.001 in the PCOS group were significantly higher than in the control group. However, the VD levels of the PCOS group were lower than the control group (p = 0.004. N1 had a strong positive correlation with BMI, HOMA-IR, hs-CRP, luteinizing hormone, systolic and diastolic BP, and HR. VD levels were negatively correlated with HOMA-IR and luteinizing hormone.Elevated N1 and decreased VD levels may be related to the presence of high-normal BP or hypertension in PCOS subjects. N1 level may be associated with an increased BP due to its relation to inflammation and IR.
Blood pressure measurement in the diagnosis and management of hypertension, including the technique required for ambulatory blood pressure monitoring and home blood pressure monitoring, will be reviewed in this article. Home and ambulatory measurements are widely used, both to confirm the diagnosis and to improve adherence to therapy. The major advantage of out-of-office blood pressure monitoring is that it provides a large number of blood pressure measurements away from the medical environment, which represents a more reliable assessment of actual blood pressure than office blood pressure. The advantage of ambulatory blood pressure monitoring is its unique ability to measure nocturnal blood pressure. Although not fully validated in large-scale clinical trials, ambulatory blood pressure monitoring appears to correlate best with prognosis. Ambulatory blood pressure monitoring and home blood pressure monitoring provide somewhat different information on the subject's blood pressure status, and the two methods should thus be regarded as complementary, rather than competitive or alternative.

If the pressure in the cuff is relieved, blood starts coming through the compressed arterial segment during systole and causes auscultatory sound and, the first sound, which, in Korotkoff’s opinion, is a measurement of systolic blood pressure. In the same BP measurement, when normal blood flow is fully restored, the auscultatory sounds disappear and, the last sound, which, in Korotkoff's opinion is a measurement of diastolic blood pressure. Listening to Korotkoff sounds (K-sounds to determine systolic and diastolic blood pressure (BP has been the standard for noninvasive BP measurement in medical practices for nearly 100 years and it is the essential tool used for evaluation and assessment of patients with hypertension and risks of cardiovascular diseases (CVD by physicians and nurses despite limited understanding of the nature of K-sounds. This article focuses particularly on the cardiovascular biomechanics of the first and last auscultatory sound and suggests two new terminologies; Highest systolic blood pressure and Baseline systolic blood pressure to represent the systolic pressure and diastolic pressure, respectively. Experimenting blood pressures on the basis of these two new suggested terminologies may reveal various additional undiscovered aspects of normal BP and abnormal BP.

Although epidemiological studies suggest that offspring of women with preeclampsia are at increased risk to higher blood pressures and cardiovascular disease, little is known about the nature of blood pressures between the mother and her offspring. As blood pressures comprise of both pulsatile (systolic blood pressure [SBP] and pulse pressure [PP]) and stable (diastolic blood pressure [DBP]) components, and they differ between central and peripheral sites, we sought to examine maternal peripheral and central blood pressure components in relation to offspring early childhood blood pressures. A prospective birth cohort of 567 Chinese, Malay, and Indian mother-offspring with complete blood pressure information were studied. Maternal brachial artery SBP, DBP, and PP were measured at 26 to 28 weeks gestation; and central SBP and PP were estimated from radial artery waveforms. Offspring brachial artery SBP, DBP, and PP were measured at 3 years of age. Associations between continuous variables of maternal blood pressures (peripheral SBP, DBP, PP, central SBP, and PP) and offspring blood pressures (peripheral SBP, DBP, and PP) were examined using multiple linear regression with adjustment for maternal characteristics (age, education level, parity, smoking status, alcohol consumption and physical activity during pregnancy, and pre-pregnancy BMI) and offspring characteristics (sex, ethnicity, BMI, and height at 3 years of age). In the multivariate models, offspring peripheral SBP increased by 0.08 (95% confidence interval 0.00-0.17, P = 0.06) mmHg with every 1-mmHg increase in maternal central SBP, and offspring peripheral PP increased by 0.10 (0.01-0.18, P = 0.03) mmHg for every 1-mmHg increase in maternal central PP. The relations of maternal-offspring peripheral blood pressures (SBP, DBP, and PP) were positive but not statistically significant, and the corresponding values were 0.05 (-0.03 to 0.13; P = 0.21), 0.03 (-0.04 to 0.10; P = 0.35), and 0.05 (-0

Full Text Available Hypertension in diabetes is a wellknown risk factor for cardiovascular diseases that should be taken seriously. Observational studies have shown a more or less linear relationship between systolic blood pressure levels and risk, but this does not correspond with the outcome results of intervention trials to lower blood pressure. In fact, tight blood pressure control has only been shown to be of general benefit in the range of 130135 mmHg systolic blood pressure, but not below except for stroke prevention. On the other hand, there might even exist an increased risk for coronary heart disease events and cardiovascular mortality at lower ranges based on data from observational studies. This fact, in combination with the increased costs and risk of serious adverse events, cautions clinicians not to lower systolic blood pressure too much in susceptible patients with longer diabetes duration, more comorbidities, and in older age groups. However, we should not lose sight of the challenge that still around half of all patients with type-2 diabetes are not even below the desired minimum goal of 140 mmHg systolic blood pressure. This calls for improved actions to control blood pressure as part of a general strategy to counteract all cardiovascular risk factors in patients with type-2 diabetes. The higher the risk, the more ambitious should be the approach to screen, detect, treat, and monitor these risk factors.

The authors tested the hypothesis that low-salt diet education by nutritionists would lower blood pressure (BP) levels in treated hypertensive patients. The amount of urinary salt excretion and clinic, home, and ambulatory BP values at baseline and at 3 months were measured in 95 patients with hypertension. After randomization to a nutritional education group (E group, n=51) or a control group (C group, n=44), the C group received conventional salt-restriction education and the E group received intensive nutritional education aimed at salt restriction to 6 g/d by nutritionists. From baseline to the end of the study, 24-hour urinary sodium excretion was significantly lowered in the E group compared with the C group (6.8±2.9 g/24 h vs 8.6±3.4 g/24 h, Pnutritionists was shown to be effective in lowering BP in treated hypertensive patients.

Full Text Available Abstract Background Automatic measurement of arterial blood pressure is important, but the available commercial automatic blood pressure meters, mostly based on oscillometry, are of low accuracy. Methods In this study, we present a cuff-based technique for automatic measurement of systolic blood pressure, based on photoplethysmographic signals measured simultaneously in fingers of both hands. After inflating the pressure cuff to a level above systolic blood pressure in a relatively slow rate, it is slowly deflated. The cuff pressure for which the photoplethysmographic signal reappeared during the deflation of the pressure-cuff was taken as the systolic blood pressure. The algorithm for the detection of the photoplethysmographic signal involves: (1 determination of the time-segments in which the photoplethysmographic signal distal to the cuff is expected to appear, utilizing the photoplethysmographic signal in the free hand, and (2 discrimination between random fluctuations and photoplethysmographic pattern. The detected pulses in the time-segments were identified as photoplethysmographic pulses if they met two criteria, based on the pulse waveform and on the correlation between the signal in each segment and the signal in the two neighboring segments. Results Comparison of the photoplethysmographic-based automatic technique to sphygmomanometry, the reference standard, shows that the standard deviation of their differences was 3.7 mmHg. For subjects with systolic blood pressure above 130 mmHg the standard deviation was even lower, 2.9 mmHg. These values are much lower than the 8 mmHg value imposed by AAMI standard for automatic blood pressure meters. Conclusion The photoplethysmographic-based technique for automatic measurement of systolic blood pressure, and the algorithm which was presented in this study, seems to be accurate.

This device provides non-invasive beat-to-beat blood pressure measurements and can be worn over the upper arm for prolonged durations. Phase and waveform analyses are performed on filtered proximal and distal photoplethysmographic (PPG) waveforms obtained from the brachial artery. The phase analysis is used primarily for the computation of the mean arterial pressure, while the waveform analysis is used primarily to obtain the pulse pressure. Real-time compliance estimate is used to refine both the mean arterial and pulse pressures to provide the beat-to-beat blood pressure measurement. This wearable physiological monitor can be used to continuously observe the beat-to-beat blood pressure (B3P). It can be used to monitor the effect of prolonged exposures to reduced gravitational environments and the effectiveness of various countermeasures. A number of researchers have used pulse wave velocity (PWV) of blood in the arteries to infer the beat-to-beat blood pressure. There has been documentation of relative success, but a device that is able to provide the required accuracy and repeatability has not yet been developed. It has been demonstrated that an accurate and repeatable blood pressure measurement can be obtained by measuring the phase change (e.g., phase velocity), amplitude change, and distortion of the PPG waveforms along the brachial artery. The approach is based on comparing the full PPG waveform between two points along the artery rather than measuring the time-of-flight. Minimizing the measurement separation and confining the measurement area to a single, well-defined artery allows the waveform to retain the general shape between the two measurement points. This allows signal processing of waveforms to determine the phase and amplitude changes.

Full Text Available Objective: The prevalence of hypertension in childhood and adolescence is gradually increasing. We aimed to investigate the blood pressure (BP values of children aged 7-18 years. Methods: This study was conducted in a total of 3375 (1777 females, 1598 males children from 27 schools. Blood pressures of children were measured using sphygmomanometer appropriate to arm circumference. Results: A positive relationship was found between systolic blood pressure (SBP and diastolic blood pressure (DBP and the body weight, height, age and body mass index (BMI in male and female children. SBP was higher in males than females after the age of 13. DBP was higher in males than the females after the age of 14. The mean annual increase of SBP was 2.06 mmHg in males and 1.54 mmHg in females. The mean annual increase of DBP was 1.52 mmHg in males and 1.38 mmHg in females. Conclusion: In this study, we identified the threshold values for blood pressure in children between the age of 7 and 18 years in Erzurum province. It is necessary to combine and evaluate data obtained from various regions for the identification of BP percentiles according to the age, gender and height percentiles of Turkish children.

Mobile phone technology using wireless monitoring tools are now widely available to help individuals monitor their blood pressure, but little is known about the conditions under which such technology can effect positive behavior changes or clinical outcomes. Objective To study the influence of wireless self-monitoring program and patient activation measures on health behaviors, medication adherence, and blood pressure levels as well as control of blood pressure in hypertensive patients. Methods We examined a subset of 95 hypertensive participants from a 6-month randomized controlled trial designed to determine the utility of a wireless self-monitoring program (n=52 monitoring program, n=43 control), which consisted of a blood pressure monitoring device connected with a mobile phone, reminders for self-monitoring, a Web-based disease management program, and a mobile app for monitoring and education, compared with the control group receiving a standard disease management program. Study participants provided measures of patient activation, health behaviors including smoking, drinking, and exercise, medication adherence, and blood pressure levels. We assessed the influence of wireless self-monitoring as a moderator of the relationship between patient activation and health behaviors, medication adherence, and control of blood pressure. Results Improvements in patient activation were associated with improvements in cigarette smoking (beta=−0.46, Pimprove their health management with an added benefit above and beyond that of motivation alone.

盐的摄入与高血压到底存在怎样的关系?多年来,人们对这个问题争论不休。现在,终于有了可靠的结论:A salty diet really does drive up bloodpressure;both in people with and without elevated pressure.本文出现了一个新的首字母缩略词DASH。《英汉大词典补编》尚未收入此词。所幸的是,本文作者对此DASH作了说明,DASH=Dietary Approaches to Stop Hypertension,我们是否可将它译成“食疗降血压法”?高血压是诱发各种心血管疾病的元凶,我们不能掉以轻心。本文的一个观点可供我们参考:An intake of sodium below thecurrent recommended daily level of 2,400 milligrams(毫克)could help Americansprevent blood pressure rises that occur especially with advancing age.
Full Text Available BACKGROUND: Blood pressure (BP measurement is a routine procedure but errors are frequently committed during BP recording. AIMS AND SETTINGS: The aim of the study was to look at the prevalent practices in the institute regarding BP recording. The study was conducted in the Medicine Department at Government Medical College, Chandigarh, a teaching institute for MBBS students. METHODS: A prospective, observational study was performed amongst the 80 doctors in a tertiary care hospital. All of them were observed by a single observer during the act of BP recording. The observer was well versed with the guidelines issued by British Hypertension Society (BHS and the deviations from the standard set of guidelines issued by BHS were noted. The errors were defined as deviations from these guidelines. STATISTICAL METHODS: The results were recorded as percentage of doctors committing these errors. RESULTS: In our study, 90% used mercury type sphygmomanometer. Zero error of the apparatus, hand dominance was not noted by any one. Every one used the standard BP cuff for recording BP. 70% of them did not let the patient rest before recording BP. 80% did not remove the clothing from the arm. None of them recorded BP in both arms. In out patient setting, 80% recorded blood pressure in sitting position and 14% in supine position. In all the patients where BP was recorded in sitting position BP apparatus was below the level of heart and 20% did not have their arm supported. 60% did not use palpatory method for noticing systolic BP and 70% did not raise pressure 30-40 mm Hg above the systolic level before checking the BP by auscultation. 80% lowered the BP at a rate of more than 2 mm/s and 60% rounded off the BP to nearest 5-10 mm Hg. 70% recorded BP only once and 90% of the rest re inflated the cuff without completely deflating and allowing rest before a second reading was obtained. CONCLUSION: The practice of recording BP in our hospital varies from the standard
Introduction: We present data on the association of manganese (Mn) level with hypertension in a representative sample of the adult Korean population who participated in the Korean National Health and Nutrition Examination Survey (KNHANES) 2008. Methods: This study was based on the data obtained by KNHANES 2008, which was conducted for three years (2007-2009) using a rolling sampling design involving a complex, stratified, multistage, probability-cluster survey of a representative sample of the noninstitutionalized civilian population of South Korea. Results: Multiple regression analysis after controlling for covariates, including gender, age, regional area, education level, smoking, drinking status, hemoglobin, and serum creatinine, showed that the beta coefficients of log blood Mn were 3.514, 1.878, and 2.517 for diastolic blood pressure, and 3.593, 2.449, and 2.440 for systolic blood pressure in female, male, and all participants, respectively. Multiple regression analysis including three other blood metals, lead, mercury, and cadmium, revealed no significant effects of the three metals on blood pressure and showed no effect on the association between blood Mn and blood pressure. In addition, doubling the blood Mn increased the risk of hypertension 1.828, 1.573, and 1.567 fold in women, men, and all participants, respectively, after adjustment for covariates. The addition of blood lead, mercury, and cadmium as covariates did not affect the association between blood Mn and the prevalence of hypertension. Conclusion: Blood Mn level was associated with an increased risk of hypertension in a representative sample of the Korean adult population. - Highlights: → We showed the association of manganese with hypertension in Korean population. → This study was based on the data obtained by KNHANES 2008. → Blood manganese level was associated with an increased risk of hypertension.

Pulse pressure in the aorta was evaluated by the measurement of pulse wave velocity (PWV) and blood flow velocity (BFV). PWV reflects the elasticity of the vessel and was determined by a time-of-flight method. BFV was measured by analyzing the change of magnetization decay due to flow in multiecho experiments. If one neglects pulse wave reflections at vascular branch points and flow resistance due to blood viscosity, pulse pressure is proportional to PWV and BFV. Noninvasive MR imaging measurements were obtained in 12 patients, all of whom underwent correlative arterial catheterization. Values varied between 35 and 100 mm Hg. The results demonstrated a high correlation between the two methods

Objective To determine the statistical characteristics of blood pressure (BP) readings from a large number of head‐injured patients. Methods The BrainIT group has collected high time‐resolution physiological and clinical data from head‐injured patients who require intracranial pressure (ICP) monitoring. The statistical features of this dataset of BP measurements with time resolution of 1 min from 200 patients is examined. The distributions of BP measurements and their relationship with simultaneous ICP measurements are described. Results The distributions of mean, systolic and diastolic readings are close to normal with modest skewing towards higher values. There is a trend towards an increase in blood pressure with advancing age, but this is not significant. Simultaneous blood pressure and ICP values suggest a triphasic relationship with a BP rising at 0.28 mm Hg/mm Hg of ICP, for ICP up to 32 mm Hg, and 0.9 mm Hg/mm Hg of ICP for ICP from 33 to 55 mm Hg, and falling sharply with rising ICP for ICP >55 mm Hg. Conclusions Patients with head injury appear to have a near normal distribution of blood pressure readings that are skewed towards higher values. The relationship between BP and ICP may be triphasic.

This study examined the role of ethnicity on the aerobic fitness, blood pressure, and selected blood chemistry values of women. One hundred twenty-four females (mean age 41.37 +/- 9.0) were medically Examined at the NASA/Johnson Space Center occupational health clinic. Ethnic groups consisted of 23 Black (B), 18 Hispanic (H) and 83 Non-minority (NM). Each woman had a maximum Bruce treadmill stress test (RER greater than or = 1.1) and a negative ECG. Indirect calorimetry, skinfolds, self-report physical activity (NASA activity scale), seated blood pressure, and blood chemistry panel determined VO2max, percent fat, level of physical activity, blood pressure and blood chemistry values. ANOVA revealed that the groups did not differ (p greater than 0.05) in age, VO2 max, weight, percent fat, level of physical activity, total cholesterol, or HDL-C. However, significant differences (p greater than 0.05) were noted in BMI, diastolic blood pressure, and blood chemistries. BMI was 3.17 higher in H than in NM; resting diastolic pressures were 5.69 and 8.05 mmHg. lower in NM and H than in B; triglycerides were 48.07 and 37.21 mg/dl higher in H than in B and NM; hemoglobin was .814 gm/dl higher in NM than B; fasting blood sugar was 15.41 mg/dl higher in H than NM; The results of this study showed that ethnic groups differed in blood pressure and blood chemistry values but not aerobic fitness or physical activity. There was an ethnic difference in BMI but not percent fat.

Objective was to assess blood pressure BP control in patients with diabetes mellitus type 2 DM type treated in primary health care. A cross-sectional study was conducted in primary health care at King Fahd Military Complex Hospital in Dhahran, Kingdom of Saudi Arabia, between August 2003 and February 2004, to assess blood control in type 2 diabetics. A sample of 403 medical records of type 2 diabetic patients was selected using systematic random sampling after ordering the medical record numbers. The data were collected through the pre-coded checklist. Hypertension was found in 57.8% of diabetic patients with no statistically significant difference between males and females. The mean age of diabetic patients was significantly highly in hypertensive than non-hypertensive p=0.001. The mean duration of hypertension was significantly higher in females p=0.02. There were only 14.2% of hypertensive diabetic patients in whom blood pressure was controlled. Poor control was significantly associated with obesity and a high rate of complications. Blood pressure control correlated positively and significantly with the age of patients and negatively with duration of diabetes and hypertension. The most commonly prescribed antihypertensive were angiotensin converting enzyme inhibitors in 29.3%, followed by angiotensin receptors blockers in 24.1%, and the least prescribed drug was thiazide diuretic. Blood pressure in diabetic patients needs to be given particular attention from all health care professionals, especially primary care family physicians, who should follow the new guideline for better control of blood pressure, and fewer complications. Patient's awareness should be increased, through continuous health education with different modalities. (author)

Full Text Available Abstract Background Prediabetes (PreDM in asymptomatic adults is associated with abnormal circadian blood pressure variability (abnormal CBPV. Hypothesis Systemic inflammation and glycemia influence circadian blood pressure variability. Methods Dahl salt-sensitive (S rats (n = 19 after weaning were fed either an American (AD or a standard (SD diet. The AD (high-glycemic-index, high-fat simulated customary human diet, provided daily overabundant calories which over time lead to body weight gain. The SD (low-glycemic-index, low-fat mirrored desirable balanced human diet for maintaining body weight. Body weight and serum concentrations for fasting glucose (FG, adipokines (leptin and adiponectin, and proinflammatory cytokines [monocyte chemoattractant protein-1 (MCP-1 and tumor necrosis factor-α (TNF-α] were measured. Rats were surgically implanted with C40 transmitters and blood pressure (BP-both systolic; SBP and diastolic; DBP and heart rate (HR were recorded by telemetry every 5 minutes during both sleep (day and active (night periods. Pulse pressure (PP was calculated (PP = SBP-DBP. Results [mean(SEM]: The AD fed group displayed significant increase in body weight (after 90 days; p Conclusion These data validate our stated hypothesis that systemic inflammation and glycemia influence circadian blood pressure variability. This study, for the first time, demonstrates a cause and effect relationship between caloric excess, enhanced systemic inflammation, dysglycemia, loss of blood pressure control and abnormal CBPV. Our results provide the fundamental basis for examining the relationship between dysglycemia and perturbation of the underlying mechanisms (adipose tissue dysfunction induced local and systemic inflammation, insulin resistance and alteration of adipose tissue precursors for the renin-aldosterone-angiotensin system which generate abnormal CBPV.

Blood pressure levels may vary in children because of genetic, ethnic and socioeconomic factors. To date, there have been no large national studies in Saudi Arabia on blood pressure in children. Therefore, we sought to establish representative blood pressure reference centiles for Saudi Arabian children and adolescents. We selected a sample of children and adolescents aged from birth to 18 years by multi-stage probability sampling of the Saudi population. The selected sample represented Saudi children from the whole country. Data were collected through a house-to-house survey of all selected households in all 13 regions in the country. Data were analyzed to study the distribution pattern of systolic (SBP) and diastolic blood pressure (DBP) and to develop reference values. The 90th percentile of SBP and DBP values for each age were compared with values from a Turkish and an American study. A total of 16 226 Saudi children and adolescents from birth to 18 years were studied. Blood pressure rose steadily with age in both boys and girls. The average annual increase in SBP was 1.66 mm Hg for boys and1.44 mm Hg for girls. The average annual increase in DBP was 0.83 mm Hg for boys and 0.77 mm Hg for girls. DBP rose sharply in boys at the age of 18 years. Values for the 90th percentile of both SBP and DBP varied in Saudi children from their Turkish and American counterparts for all age groups. Blood pressure values in this study differed from those from other studies in developing countries and in the United States, indicating that comparison across studies is difficult and from that every population should use their own normal standards to define measured blood pressure levels in children.

Full Text Available Judith A WhitworthJohn Curtin School of Medical Research, Australian National University, Canberra, ACT, AustraliaAbstract: Two key early 20th century notions, the first the primacy of diastolic pressure in determining risk, and the second that hypertension is a discrete disorder, have proved to be incorrect. We now recognize the primacy of systolic pressure as a risk factor for cardiovascular disease and that hypertension is an arbitrary definition. In the early 21st century, we are moving away from a dichotomous approach to risk classification, and away from notions of hypertension and normotension towards an appreciation that blood pressure-related risk is continuous. In parallel, there has been a paradigm shift from a single risk factor approach to comprehensive cardiovascular disease risk prevention. Accordingly, prevention of cardiovascular disease requires a focus on lowering of blood pressure and modification of associated risk factors rather than simply treatment of hypertension. This emphasis is reflected in the World Health Organization (WHO – International Society of Hypertension (ISH 2003 statement on management of hypertension.Keywords: blood pressure, hypertension, cardiovascular risk, treatment

In this paper, the oscillometric waveform measured by automatic non-invasive blood pressure meters (NIBP) is analyzed by transforming the data from the time domain to the frequency domain. The signal's spectrum of the oscillometric waveform is in current literature badly understood or explored. The only known link between the oscillometric waveform and the blood pressure is the maximum of the oscillometry's envelope equalling the mean arterial pressure (MAP). This link is established under the assumption that the oscillometry is an AM-signal. Unfortunately, computing the MAP is difficult in practice due to the non-sinusoidal nature of the actual measured signals. In this paper, we construct the best AM-signal approximation of the oscillometry and explore its use to compute the MAP.

Hypertension confers increased risk for cognitive decline, dementia, and cerebrovascular disease. These associations have been attributed, in part, to cerebral hypoperfusion. Here we posit that relations of higher blood pressure to lower levels of cerebral perfusion may be potentiated by a prior head injury. Participants were 87 community-dwelling older adults - 69% men, 90% white, mean age=66.9years, 27.6% with a history of mild traumatic brain injury (mTBI) defined as a loss of consciousness ≤30min resulting from an injury to the head, and free of major medical (other than hypertension), neurological or psychiatric comorbidities. All engaged in clinical assessment of systolic and diastolic blood pressure (SBP, DBP) and single photon emission computed tomography (SPECT). Computerized coding of the SPECT images yielded relative ratios of blood flow in left and right cortical and select subcortical regions. Cerebellum served as the denominator. Sex-stratified multiple regression analyses, adjusted for age, education, race, alcohol consumption, smoking status, and depressive symptomatology, revealed significant interactions of blood pressure and head injury to cerebral blood flow in men only. Specifically, among men with a history of head injury, higher systolic blood pressure was associated with lower levels of perfusion in the left orbital (β=-3.21, p=0.024) and left dorsolateral (β=-2.61, p=0.042) prefrontal cortex, and left temporal cortex (β=-3.36, p=0.014); higher diastolic blood pressure was marginally associated with lower levels of perfusion in the left dorsolateral prefrontal cortex (β=-2.79, p=0.051). Results indicate that men with a history of head injury may be particularly vulnerable to the impact of higher blood pressure on cerebral perfusion in left anterior cortical regions, thus potentially enhancing risk for adverse brain and neurocognitive outcomes.

Full Text Available Systemic arterial blood pressures were measured in 30 dogs with acute babesiosis, 10 each with mild uncomplicated, severe uncomplicated and complicated disease. Ten healthy dogs were used as controls. Hypotension was defined as more than 3 standard deviations below the control mean. Normal mean pressures (Â±SD were: systolic arterial pressure 151 (Â±11 mm Hg, diastolic arterial pressure 89 (Â±8 mm Hg and mean arterial pressure 107 (Â±10 mmHg. Hypotension was the most frequent abnormality, and increased strikingly in incidence as disease severity increased, with 5/10 dogs in the complicated group being hypotensive for systolic, diastolic and mean arterial pressures, compared with 2/10 in the severe uncomplicated group and 0/10 in the mild uncomplicated group. Systolic, diastolic and mean arterial pressures in the complicated group and severe uncomplicated group, and systolic pressure in the mild uncomplicated group, were significantly lower than in the controls. There were no significant relationships between arterial pressures and age, pulse rate, respiratory rate, temperature, mucous membrane colour or haematocrit. There was a significant negative correlation between arterial pressures and white cell and immature neutrophil counts. Arterial pressures differed significantly between dogs that were clinically collapsed and those that were not, but not between survivors and non-survivors. Pulse pressure (systolic - diastolic was low in 7/10 complicated, 1/10 mild uncomplicated, and 1/10 severe uncomplicated cases, and differed significantly between the complicated and control groups. The high incidence of hypotension in clinically severe babesiosis has important implications for therapy.

Full Text Available Background: More attention is being paid lately to polycystic ovary syndrome (PCOS not only in the aspect of fertility but also according to long-term metabolic and cardiovascular abnormalities. Observations of women with PCOS show that the occurrence of blood hypertension is more frequent after the menopause. There are few articles concerning the predictable symptoms of blood hypertension. It seems that twenty-four hour blood pressure monitoring and assessment of changes of diurnal rhythm could be useful in this group of patients.Aim of the study: The purpose of this study was to assess diurnal changes of blood pressure in women with polycystic ovary syndrome.Material and methods: 26 women with PCOS diagnosed according to Rotterdam consensus criteria and Androgen Excess Society (AES criteria were included in our study. The mean age of the examined women was 29.5 years and the mean BMI (body mass index was 24.7 kg/m2. The control group consisted of 12 age-matched women, without PCOS. Twenty-four hour Holter monitoring of ambulatory blood pressure was performed during normal daily activity in all patients. Halberg’s cosinor method was used to analyse daily biorhythm.Results: Results show the diurnal changes of systolic blood pressure in the preclinical phase in 30% and diastolic in 15% of PCOS women. In this group no physiological decrease of blood pressure at night time was observed.

Background: Developmental dyslexia is a neurodevelopmental learning disability characterised by unexpectedly poor reading and unknown aetiology. One hypothesis proposes excessive platelet activating factor, a potent vasodilator, as a contributor, implying that there should be a negative association between dyslexia and high blood pressure (HBP).

This article looks at the association of maternal blood pressure with the blood pressure of the offspring from birth to childhood. The Barker hypothesis states that maternal and "in utero" attributes during pregnancy affect a child's cardiovascular health throughout life. We present an analysis of a unique dataset that consists of three distinct developmental processes: maternal cardiovascular health during pregnancy; fetal development; and child's cardiovascular health from birth to 14 years. This study explored whether a mother's blood pressure reading in pregnancy predicts fetal development and determines if this in turn is related to the future cardiovascular health of the child. This article uses data that have been collected prospectively from a Jamaican cohort which involves the following three developmental processes: (1) maternal cardiovascular health during pregnancy which is the blood pressure and anthropometric measurements at seven time-points on the mother during pregnancy; (2) fetal development which consists of ultrasound measurements of the fetus taken at six time-points during pregnancy; and (3) child's cardiovascular health which consists of the child's blood pressure measurements at 24 time-points from birth to 14 years. The inter-relationship of these three processes was examined using linear mixed effects models. Our analyses indicated that attributes later in childhood development, such as child's weight, child's baseline systolic blood pressure (SBP), age and sex, predict the future cardiovascular health of children. The results also indicated that maternal attributes in pregnancy, such as mother's baseline SBP and SBP change, predicted significantly child's SBP over time. PMID:25178900

In this paper, a simulation model based on the partially pressurized collapsible tube model for reproducing noninvasive blood pressure measurement is presented. The model consists of a collapsible tube, which models the pressurized part of the artery, rigid pipes connected to the collapsible tube, which model proximal and distal region far from the pressurized part, and the Windkessel model, which represents the capacitance and the resistance of the distal part of the circulation. The blood flow is simplified to a one-dimensional system. Collapse and expansion of the tube is represented by the change in the cross-sectional area of the tube considering the force balance acting on the tube membrane in the direction normal to the tube axis. They are solved using the Runge-Kutta method. This simple model can easily reproduce the oscillation of inner fluid and corresponding tube collapse typical for the Korotkoff sounds generated by the cuff pressure. The numerical result is compared with the experiment and shows good agreement. PMID:16995754
Intrapulmonary administration of natural honey solution, hyperosmolar dextrose or hypoosmolar distill water to normal individuals and to patients with type-2 diabetes mellitus or hypertension: their effects on blood glucose level, plasma insulin and C-peptide, blood pressure and peaked expiratory flow rate.
Safety and effect intrapulmonary administration (by inhalation) of 60 % honey solution, 10% dextrose or distill water on blood sugar, plasma insulin and C-peptide, blood pressure, heart rate, and peaked expiratory flow rate (PEFR) in normal or diabetic subjects were studied. - Twenty-four healthy subjects, 16 patients with type 11 diabetes mellitus and six patients with hypertension were entered for study. They were underwent complete physical examination and laboratory investigations. Twelve healthy subjects were subjected for distill water inhalation for 10 min, and after one week they received inhalation of honey solution (60% wt/v) for 10 min. Another 12 healthy subjects received inhalation of 10% dextrose for 10 min. Blood glucose level, plasma insulin and C-peptide, blood pressure, heart rate and PEFR were estimated before inhalation and during 2-3 hrs after inhalation, at 30 min intervals. Random blood glucose level was estimated in eight patients with poorly controlled diabetes mellitus, and repeated 30 min after honey inhalation. One week later, fasting blood glucose level was estimated in each patient and blood glucose level was re-estimated during three hrs after honey inhalation, at 30 min intervals. Glucose tolerance test was performed in another eight patients with type-2 diabetes mellitus, and after one week the procedure was repeated with inhalation of honey, which was started immediately after ingestion of glucose. Six hypertensive patients received honey inhalation for 10 min; supine blood pressure and heart rate were measured before and after inhalation. - Results showed that in normal subjects distill water caused mild elevation of blood glucose level, mild lowering of plasma insulin, and significant reduction of plasma C-peptide. 10% dextrose inhalation caused mild reduction of plasma insulin and C-peptide and unremarkable changes in blood glucose level. No significant changes were obtained in blood pressure, heart rate or PEFR after distill

BACKGROUND: -Smoking is an important cardiovascular disease risk factor, but the mechanisms linking smoking to blood pressure are poorly understood. METHODS AND RESULTS: -Data on 141,317 participants (62,666 never, 40,669 former, 37,982 current smokers) from 23 population-based studies were...... included in observational and Mendelian randomisation (MR) meta-analyses of the associations of smoking status and smoking heaviness with systolic and diastolic blood pressure (SBP, DBP), hypertension, and resting heart rate. For the MR analyses, a genetic variant rs16969968/rs1051730 was used as a proxy...... association of smoking heaviness with higher level of resting heart rate, but not with blood pressure. These findings suggest that part of the cardiovascular risk of smoking may operate through increasing resting heart rate....

There is considerable interest in blood pressure reactivity to psychological stressors. Because the sympathetic nervous system and the renin-angiotensin system are so responsive to stressors and are themselves the targets of many antihypertensive medications, many investigators have wondered if such medications decrease the blood pressure response to stressful stimuli. We studied 25 normotensive and 21 hypertensive men in a double-blind crossover study during which they received either placebo for 4 days or captopril (25 mg b.i.d.) for 4 days while they were hospitalized in a clinical research center. Patients were studied at resting baseline, while performing a mathematics task, and while reading out loud a disturbing newspaper article. Although captopril lowered the resting blood pressure levels, it had no effect on the amplitude of reactivity to stressors. PMID:1639462
贵刊去年第6期曾刊登一短文,题目是:盐,迫升血压之元凶。读了该文,我开始严格控制每日的食盐摄入量,再附以药物治疗,血压果然趋于平稳。近日上网,遇一奇文,意思是人的血压与空气污染状况有涉!根据对2600个成年人的调查,得出了这样的结论:Pollution may cause changes in the part of the nervous system that controls blood pressure.文章又同时说明:Exactly how pollution might cause blood pressure to climb remains unclear.人体之奥妙由此可见一斑。

A fall in systolic blood pressure without other symptoms of anaphylactic shock has been described following the administration of drugs containing dipyrone. This adverse reaction was first observed in 4 patients by the same team in 1972-1973. Ten further cases with a fall in systolic blood pressure by at least 20 mm Hg occurring within minutes to 6 hours after intravenous administration of dipyrone are presented in this paper. In each of them this adverse reaction was considered to be probable or even definite. During the years 1976-1981 drug exposure was registered for all 15 678 patients of the two medical divisions of Comprehensive Hospital Drug Monitoring Berne. This adverse reaction was found in 7, representing 0.34% of the 2053 patients who received intravenous treatment with a dipyrone preparation. PMID:6658424

Lemon juice has commonly been used by hypertensive patients in order to lower blood pressure (BP) acutely when BP is raised or as an alternative/complementary therapy for expectation of chronic improvement. Grapefruit, a citrus fruit like lemon, causes clinically significant interactions with a variety of drugs including calcium antagonists. The aims of this study were to investigate acute and chronic effects of lemon juice on BP among hypertensive patients. Ninty-eight patients were included...

Patients requiring aortography frequently suffer from generalized arteriosclerosis. Uncontrolled hypotension is therefore clearly undesirable, especially if associated with myocardial depression. Significant hypotension was observed following the use of conventional ionic contrast media, Urografin 370 and Cardioconray, and occurred following every injection in this study. Metrizamide, a non-ionic contrast medium, was found to be associated with a smaller fall in blood pressure of a shorter du...

As our understanding of the underlying aetiology of hypertension is far from adequate, over 90% of patients with hypertension receive a diagnosis of essential hypertension. This non-specific diagnosis leads to suboptimal therapeutics and a major problem with non-compliance. Understanding the normal control of blood pressure (BP) is, hence, important for a better understanding of the disease.This review attempts to unravel the present understanding of BP control. The local mechanisms of BP con...

There is growing concern about elevated blood pressure (BP) in children. The evidence for familial aggregation of childhood BP is substantial. Twin studies have shown that a large part of the familial aggregation of childhood BP is due to genes. The first part of this review provides the latest progress in gene finding for childhood BP, focusing on the combined effects of multiple loci identified from the genome-wide association studies on adult BP. We further review the evidence on the contr...
