    Full Text Available Ambulatory blood pressure monitoring (ABPM is a modern method of blood pressure (BP investigation recommended by international scientific associations for diagnostics of essential hypertension (EH. However, there are some methodological aspects which are not regulated. Particularly, ABPM parameters have not yet established for those patients in different age groups and pathologies. The aim of the study was to determine peculiarities of ABPM parameters in treated controlled hypertensive and normotensive patients. Materials and methods. 71 patients were included into the study and divided into two groups according to the level of 24-h systolic BP (SBP and 24-h diastolic BP (DBP. There were 50 controlled patients with EH in the first group and 21 normotensive individuals without EH in the second group. Results. In EH patients and normotensive individuals we had statistician difference of such parameters, like the hypertension time index (TI of day SBP parameters (20 (8–31 % vs. 8 (4–18 %; р=0.040; of the square index (SI of hypertension (24 (11–41 mm2/h vs. 8 (2–23 mm2/h; р=0.021; of the square index normalized (SIN of hypertension (1.4 (0.6–2.4 U vs. 0.4 (0.1–1.2 U; р=0.018, and the morning surge of SBP (45±14 mm Hg vs. 37±14 mm Hg; р=0.028, respectively. There is no different in other ABPM parameters. Conclusion. The present data shows that treated controlled hypertensive patients and individuals without EH have statistician difference only in daily SBP of hypertensive indexes (TI, SI, SIN and the morning surge of SBP. The other ABPM parameters, included new one, such as the arterial stiffness index, did not represent statistical difference between groups.

    The aim was to determine the proportions and correlates of essential hypertension among children in a tertiary pediatric hypertension clinic. We evaluated 423 consecutive children and collected demographic and clinical history by retrospective chart review. We identified 275 (65%) hypertensive children (blood pressure >95th percentile per the "Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents") from 423 children referred to the clinic for history of elevated blood pressure. The remainder of the patients had normotension (11%), white coat hypertension (11%), prehypertension (10%), and pending diagnosis (3%). Among the 275 hypertensive children, 43% (n = 119; boys = 56%; median age = 12 years; range = 3-17 years) had essential hypertension and 57% (n = 156; boys = 66%; median age = 9 years; range = 0.08-19 years) had secondary hypertension. When compared with those with secondary hypertension, those with essential hypertension had a significantly older age at diagnosis (P = 0.0002), stronger family history of hypertension (94% vs. 68%; P secondary hypertension. The phenotype of essential hypertension can present as early as 3 years of age and is the predominant form of hypertension in children after age of 6 years. Among children with hypertension, those with essential hypertension present at an older age, have a stronger family history of hypertension, and have lower prevalence of preterm birth. © American Journal of Hypertension, Ltd 2014.

    High blood pressure causes left ventricular hypertrophy, which is a negative prognostic factor among hypertensive patients. To assess left ventricular geometric remodeling patterns in patients with essential hypertension or with hypertension secondary to parenchymal renal disease. We analyzed data from echocardiograms performed in 250 patients with essential hypertension (150 females) and 100 patients with secondary hypertension (60 females). The interventricular septum and the left ventricular posterior wall thickness were measured in the parasternal long-axis. Left ventricular mass was calculated using the Devereaux formula. The most common remodeling type in females and males with essential hypertension were eccentric and concentric left ventricular hypertrophy (cLVH), respectively. Among patients with secondary arterial hypertension, cLVH was most commonly observed in both genders. The prevalence of left ventricular hypertrophy was higher among patients with secondary hypertension. The left ventricular mass index and the relative left ventricular wall thickness were higher in males and also in the secondary hypertension group. Age, blood pressure values and the duration of hypertension, influenced remodeling patterns. We documented a higher prevalence of LVH among patients with secondary hypertension. The type of ventricular remodeling depends on gender, age, type of hypertension, blood pressure values and the duration of hypertension.

    This study was to evaluate the effects of foot reflexology on blood pressure, serum lipids level and life satisfaction in essential hypertension patients. The research design used was a nonequivalent control group pretest-posttest design. Foot Reflexology was used as the experimental treatment from June 23rd, 2003 until August 31st, 2003. Thirty-four subjects were assigned to an experimental group(18) and control group(16). Foot Reflexology was administered twice a week for 6 weeks and self foot Reflexology was administered twice a week for 4 weeks on the experimental group. There was a significant decrease in systolic blood pressure but no significant decrease in diastolic pressure in the experimental group compared to the control group. The total cholesterol level in the experimental group compared to the control group was not significantly decreased after foot reflexology. However, the triglyceride level in the experimental group compared to the control group was significantly decreased after foot reflexology. On the other hand, high density lipoprotein and low density lipoprotein levels in the experimental group compared to the control group was not significantly decreased after foot reflexology. Life satisfaction in the experimental group compared to the control group was significantly improved after foot reflexology. The results proved that foot reflexology was an effective nursing intervention to decrease systolic pressure, and triglyceride but not for the blood cholesterol and to improve life satisfaction. Therefore, blood cholesterol should be further evaluated in a larger group of subjects and for a longer period. Further research is regarded as necessary to evaluate and to compare effects of self-foot reflexology and foot reflexology.

    Objective: To investigate the change of serum insulin level in essential hypertension patients and its relationship with age and sex. Methods: The levels of serum insulin were determined with radioimmunoassay in 980 essential hypertension patients and 120 controls. Results: The levels of serum insulin in the essential hypertension patients were significantly higher than those in the controls (t=4.280, P<0.01). However, there were no significant differences among the levels in different sex and age groups. The same held true for women before and after menopause as well as different stages of hypertension. Conclusion: The average serum insulin level in EH patients was significantly higher than the level in controls, and had positive correlation to mean arterial pressure. But no significant differences were found among different sex and age groups, so serum insulin could be a new independent risk factor of essential hypertension

    Objective: To investigate the relationship between serum tumor necrosis factor-α (TNF-α) levels and insulin resistance (IR) in patients with essential by pertension. Methods: Serum TNF-α and free insulin (fINS)levels were measured with RIA in 41 patients with essential hypertension and 38 controls. Insulin resistance was calculated with insulin resistance index (HOMA-IR). Results: The serum TNF-α levels were significantly higher in patients with essential hypertension than those in the controls (P<0.001). The HOMA-IR was also significantly higher in hypertension group than that in controls (P<0.001). Serum TNF-α levels was positively correlated with BMI, HOMA-IR and SBP both in hypertension group and control group (P<0.05). Conclusion: Serum TNF-α level was increased in hypertensive patients and positively correlated with obesity and IR. (authors)

    Objective: To investigate the changes of plasma contents of TXB 2 after aspirin treatment in patients with essential hypertension. Methods: Plasma TXB 2 contents were measured with RIA in 105 patients with essential hypertension and 42 controls. Fifteen patients were given aspirin 100 mg/d x 15 days and plasma TXB 2 were measured again after completion of the treatment. Results: Plasma TXB 2 contents in patients with essential hypertension were significantly higher than those in controls (P<0. 01) with no sex differences. After a course of treatment with aspirin, the levels were significantly lowered (vs before treatment, P < 0.01 ). Conclusion: Hypercoagulability was present in patients with essential hypertension and could be corrected with aspirin treatment. (authors)

    Objective: To study the changes of plasma neuropeptide Y(NPY) and neurotension (NT) levels in patients with essential hypertension after treatment with carvedilol. Methods: Blood pressure and plasma NPY and NT concentrations (with RIA) were measured in 56 patients with essential hypertension both before and after carvedilol therapy (5-10 mg bid) for 3 months as well as 30 controls. Results: Before treatment plasma NPY levels were significantly higher in hypertensive patients than those in controls (P<0.01), but plasma NT levels were significantly lower (P also <0.01). After carvedilol treatment, blood pressure and plasma NPY levels were reduced significantly and plasma NT levels were increased significantly. Conclusion: Treatment with carvedilol results in the correction of plasma concentrations of NPY and NT in patients with essential hypertension, the effect may be related to blood pressure decrease.

    2011-10-01

    To compare effects of valsartan and benazepril on erythropoietin (EPO) levels in essential hypertensive patients with normal renal function. Sixty essential hypertensive patients were randomly divided into valsartan group (n=30, valsartan 80 mg/day) and benazepril group (n=30, benazepril 10 mg/day). Plasma EPO and hemoglobin (Hb) levels were measured at the start of and at 4 and 8 weeks during the treatments. EPO and Hb levels were all in normal range in the two groups. Valsartan decreased EPO levels from 14.179∓3.214 U/L (baseline) to 12.138∓2.926 U/L (PBenazepril treatment did not resulted in any obvious changes in EPO or Hb levels (P>0.05). Valsartan may lower EPO and Hb levels in patients with essential hypertension, while benazepril does not have such effects. The safety of valsartan in anemic hypertensive patients should be further investigated.

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

    Full Text Available Background. To simplify traditional Chinese medicine syndrome differentiation and allow researchers to master syndrome differentiation for hypertension, this paper retrospectively studied the literature and analyzed syndrome elements corresponding to hypertension syndromes. Methods. Six databases including PubMed, EMBASE, Chinese Bio-Medical Literature Database, Chinese National Knowledge Infrastructure, Chinese Scientific Journal Database, and Wan-fang Data were searched from 1/January/2003 to 30/October/2013. We included all clinical literature testing hypertension syndromes and retrospectively studied the hypertension literature published from 2003 to 2013. Descriptive statistics calculated frequencies and percentages. Results. 13,272 patients with essential hypertension were included. Clinical features of hypertension could be attributed to 11 kinds of syndrome factors. Among them, seven syndrome factors were excess, while four syndrome factors were deficient. Syndrome targets were mainly in the liver and related to the kidney and spleen. There were 33 combination syndromes. Frequency of single-factor syndromes was 31.77% and frequency of two-factor syndromes was 62.26%. Conclusions. Excess syndrome factors of hypertension patients include yang hyperactivity, blood stasis, phlegm turbidity, internal dampness, and internal fire. Deficient syndrome factors of hypertension patients are yin deficiency and yang deficiency. Yin deficiency with yang hyperactivity, phlegm-dampness retention, and deficiency of both yin and yang were the three most common syndromes in clinical combination.

    In the development of hypertensive microvascular remodeling, a relevant role may be played by changes in extracellular matrix proteins. Aim of this study was the to evaluate some extracellular matrix components within the tunica media of subcutaneous small arteries in 9 normotensive subjects and 12 essential hypertensive patients, submitted to a biopsy of subcutaneous fat from the gluteal or the anterior abdominal region. Subcutaneous small resistance arteries were dissected and mounted on an isometric myograph, and the tunica media to internal lumen ratio was measured. In addition, fibronectin, laminin, transforming growth factor-beta-1 (TGF-β1) and emilin-1 contents within the tunica media were evaluated by immunofluorescence and relative immunomorphometrical analysis (immunopositivity % of area). The total collagen content and collagen subtypes within the tunica media were evaluated using both Sirius red staining (under polarized light) and immunofluorescence assay. Normotensive controls had less total and type III collagen in respect with hypertensive patients. Fibronectin and TGF-β1 tunica media content was significantly greater in essential hypertensive patients, compared with normotensive controls, while laminin and emilin-1 tunica media content was lesser in essential hypertensive patients, compared with normotensive controls. A significant correlation was observed between fibronectin tunica media content and media to lumen ratio. Our results indicate that, in small resistance arteries of patients with essential hypertension, a relevant fibrosis may be detected; fibronectin and TGF-β1 tunica media content is increased, while laminin and emilin-1 content is decreased; these changes might be involved in the development of small resistance artery remodeling in humans.

    The elimination rate (percent per day) of injected 22 Na using a whole body measurement technique was significantly lower (26%, 5.8 +- 1.5) in normotensive of borderline hypertensive offspring of essential hypertensive patients than in 15 age- and sex-matched, normotensive controls (7.3 +- 1.0). There were no significant differences in exchangeable sodium, whole body potassium or in the urinary exeretion of sodium, potassium and creatinine. The basis for the difference in turnover rate during weck 1 is probably an alteration in the cellular handling of sodium (i.e. increased intracellular sodium) in the still normotensive offspring of patients with essential hypertension. The long-term (more than 100 days) whole body retention of 22 Na was found to be only 0.1% of that injected, which justifies the use of the method on larger population groups. (orig.)

    Oxidative stress seems to play an important role in the pathophysiology of essential hypertension. We aimed to examine serum MDA, NO, 8-OHdG, ADMA, NT, CoQ10 and TAC as biomarkers of oxidative stress in dipper and non-dipper hypertensive patients. Eighteen dipper hypertensives, 20 non-dipper hypertensives and 22 healthy control subjects were included in the study. Clinical assessment and ambulatory blood pressure monitoring were performed in patients. Serum MDA, TAC and NO levels were measured by using spectrophotometric methods. CoQ10 levels were measured by HPLC method. 8-OHdG, ADMA and NT were quantitated by ELISA methods. MDA levels were significantly higher in dipper and non-dipper groups compared to controls (pstres compared with dipper hypertensive patients, which plays an important role in the development of cardiovascular diseases. Increased MDA and reduced TAC levels might be considered as prospective prognostic markers of the development of cardiovascular diseases in dipper and non-dipper hypertensive patients.

    Full Text Available PURPOSE - To evaluate diastolic dysfunction (DD in essential hypertension and the influence of age and cardiac geometry on this parameter. METHODS - Four hundred sixty essential hypertensive patients (HT underwent Doppler echocardiography to obtain E/A wave ratio (E/A, atrial deceleration time (ADT, and isovolumetric relaxation time (IRT. All patients were grouped according to cardiac geometric patterns (NG - normal geometry; CR - concentric remodeling; CH- concentric hypertrophy; EH - eccentric hypertrophy and to age (60 years. One hundred six normotensives (NT persons were also evaluated. RESULTS - A worsening of diastolic function in the HT compared with the NT, including HT with NG (E/A: NT - 1.38±0.03 vs HT - 1.27±0.02, p<0.01, was observed. A higher prevalence of DD occurred parallel to age and cardiac geometry also in the prehypertrophic groups (CR. Multiple regression analysis identified age as the most important predictor of DD (r²=0.30, p<0.01. CONCLUSION - DD was prevalent in this hypertensive population, being highly affected by age and less by heart structural parameters. DD is observed in incipient stages of hypertensive heart disease, and thus its early detection may help in the risk stratification of hypertensive patients.

    An impaired ability to experience and express emotions, known as alexithymia, has previously been associated with hypertension. Alexithymia and related emotion-processing variables, however, have never been examined as a function of the type of hypertension, essential (EH) or secondary (SH). Our working hypothesis was that if dysregulated emotional processes play a key neurobiological role in EH, they would be less present in hypertension due to specific medical causes or SH. A total of 98 consecutive hypertensive patients (73 EH, 25 SH) with similar blood pressure levels completed two complementary measures of emotion processing: the 20-item Toronto Alexithymia Scale (TAS-20) and the Levels of Emotional Awareness Scale (LEAS). After controlling for confounding variables, LEAS score was lower in EH than SH (estimated means: 46.4 vs. 52.0; P = 0.028; effect size 0.52). TAS-20 scores did not differentiate EH from SH, but the differences were in the expected direction, with an effect size of 0.34 for TAS-20 total score. Neither psychometric measure was associated with the duration of hypertension or the presence of cardiovascular (CV) complications. These results are consistent with a contribution of an emotional or psychosomatic component in EH and may have practical implications for the nonpharmacological management of hypertension. They also demonstrate the utility of complementary measures of emotion processing in medically ill patients.

    Aldosterone (ALD) secretion is regulated mainly by angiotensin II, K(+), and adrenocorticotropic hormone (ACTH). Mineralocorticoid receptor antagonists (MRAs) have effectively been used for the treatment of patients with hypertension who do not have primary aldosteronism (PA). We tested whether chronic stress-related ACTH-mediated ALD hypersecretion and/or zona glomerulosa hypersensitivity could be implicated in the pathogenesis of essential hypertension (ESHT). One hundred thirteen hypertensives without PA and 61 normotensive controls underwent an ultralow-dose (0.03-μg) ACTH stimulation and a treadmill test. Patients with ALD hyper-response according to the cutoffs obtained from controls received treatment with MRAs and underwent genomic DNA testing for the presence of the CYP11B1/CYP11B2 chimeric gene and KCNJ5 gene mutations. A control group of 22 patients with simple ESHT received treatment with MRAs. Based on the cutoffs of ALD and aldosterone-to-renin ratio (ARR) post-ACTH stimulation obtained from controls, 30 patients (27%) exhibited an ALD but not cortisol (F) hyper-response (HYPER group). This group had no difference in basal ACTH/renin (REN) concentrations compared with controls and the 83 patients with hypertension (73%) without an ALD hyper-response to ACTH stimulation. Patients in the HYPER group demonstrated significantly higher ALD concentrations, ARR, and ALD/ACTH ratio (AAR) in the treadmill test. Treatment with MRAs alone produced normalization of blood pressure in these patients whereas patients with hypertension with neither PA nor ALD hyper-response to ACTH stimulation who served as a control group failed to lower blood pressure. Also, two novel germline heterozygous KCNJ5 mutations were detected in the HYPER group. A number of patients with hypertension without PA show ACTH-dependent ALD hyper-secretion and benefit from treatment with MRAs. This could be related to chronic stress via ACTH hyper secretion and/or gene-mutations increasing the

    The arteries calcification index is a quantitative, mathematically estimated parameter characterizing the total amount of calcium within atherosclerotic plaques in the walls of arteries. The objective is to determine a relationship between exposure to cigarette smoke and the carotid arteries calcification index in patients with essential hypertension. The tested group included 66 patients with essential hypertension: 19 active smokers (subgroup A), 20 non-smokers, environmentally exposed to cigarette smoke (subgroup B) and 27 persons without exposure to cigarette smoke (subgroup C). The tested group was subjected to computed tomography angiography of carotid arteries. Evaluation of the carotid arteries calcification indexes was conducted. The average value of the total calcification index of the carotid arteries (CAci) amounted to 368.28 ± 384.21. In subgroup A and B in relation to subgroup C, CAci was significantly higher. In summary, active and passive smoking in patients with essential hypertension may be associated with a higher calcification index of carotid arteries.

    Angiotensin converting enzyme (ACE) inhibiting drugs are able to reduce urinary protein excretion in experimental hypertension and in hypertensive patients with diabetes. Fifteen essential (group I) and six renal parenchymal (group II) mild or moderate hypertensive patients were treated with the ACE inhibitor Enalapril in monotherapy or in combination with a diuretic. Twenty-four hour urinary protein excretion was measured by means of colorimetric and RIA methods. All patients of group I had a significant decrease of arterial pressure with Enalapril alone and this reduction was dosage dependent. Three out of six patients of group II required the addition of diuretic to achieve a good pressure control. Serum creatinine values were stable in group I, while one patient of group II, who already had high baseline creatinine levels, showed an impairment of renal function requiring discontinuation of therapy. Twenty-four hour urinary protein excretion did not change in group I, while after two months of therapy a significant decrease was observed in group II (P<0.05), which was even more evident after 4 months (P<0.03). In this group a good correlation between MAP and proteinuria was observed. Finally, compared to the colorimetric method, RIA method seems to be more sensitive to assess the variations under Enalapril treatment. In conclusion, Enalapril is an effective drug in patients with moderate or mild hypertension. Caution must be exercised in administering Enalapril to patients with severe renal failure. Also in hypertensive patients with mild renal failure ACE inhibition appears to induce an antiproteinuric effect during long term therapy. This fact could be related to an improved hemodynamic intraglomerular status due to the renal effects of the drug. Finally urinary albumin RIA method seems to be more sensitive than colorimetric evaluation to follow-up the variations of proteinuria under Enalapril treatment

    To investigate the effect of benazepril on plasma homocysteine (Hcy) levels and to analyze the correlation between the methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and changes in Hcy levels in response to benazepril. A total of 231 patients with mild to moderate essential hypertension were enrolled, and benazepril was orally administered at a dose of 10 mg/d for 2 weeks. Plasma Hcy levels were measured by high-performance liquid chromatography at baseline and after 2 weeks of treatment. Genotyping of the MTHFR C677T polymorphism was performed by TaqMan probe technique. There was no significant change in Hcy level after benazepril treatment for 2 weeks (P = .97). However, stratified by baseline Hcy levels, the patients with baseline Hcy benazepril treatment. There were also no statistically significant interactions of gene and environment factors (ie, gene smoking and drinking) on the changes in Hcy levels after benazepril treatment. Benazepril may cause an increase in plasma Hcy levels among patients with hypertension with low baseline Hcy levels, while effect modification by MTHFR C677T genotypes on the changes in Hcy levels in response to benazepril was not significant among patients with essential hypertension. © The Author(s) 2015.

    Adiponectin is an adipocyte-derived protein with insulin-sensitizing and antiatherogenic properties. Failure to decrease blood pressure (BP) normally during night in hypertensive patients has been independently associated with left ventricular hypertrophy. We examined the relationship between adiponectin levels, insulin sensitivity, and left ventricular structure in 40 newly diagnosed never-treated patients with essential hypertension, including 20 patients with a normal night-time pressure decrease (ie, dippers) and 20 patients with BP persistently elevated throughout the 24-h period (ie, nondippers). All subjects had grade 1-2 hypertension, aged 18 to 65 years, no diabetes mellitus, no obesity, no hyperlipidemia, and no cardiopulmonary, renal, or hepatic disease. The two groups of patients were similar for age, sex, body mass index, and had no differences for clinic, 24-h, and diurnal BP, and 24-h, diurnal, and nocturnal heart rate, as well as glucose, total cholesterol, and triglyceride levels. Plasma insulin and homeostasis model assessment (HOMA index) were higher (P < .01), and adiponectin levels were lower (P < .005) in nondippers than in dippers. Adiponectin correlated inversely with HOMA index and insulin levels (r = -0.58, and r = -0.62, respectively, P < .001) in the entire population. Nondippers showed left ventricular mass, relative wall thickness, and measure of early and late diastolic peak flow velocity ratio similar to those of dippers. In the absence of major cardiovascular risk factors, nondipper essential hypertensive patients show more prominent insulin resistance and lower adiponectin compared to dippers. Therapeutic modulation of adiponectin or insulin resistance might provide additional benefit to the conventional antihypertensive treatment.

    Hypertension is common a health problem and its prevalence in Indonesia is quite high (31.7%). Catgut embedding—an acupuncture technique—is known to reduce blood pressure; however, no study has confirmed the underlying mechanism. This study examines the effect of catgut embedding on serum nitric oxide (NO) concentration and blood pressure in patients with essential hypertension. Forty hypertension patients were randomly assigned to two groups: the control group received anti-hypertensive drugs whereas the case group received anti-hypertensive drugs and catgut embedding. Results showed a statistically significant mean difference in NO concentration (p < 0.05) and statistically and clinically significant mean difference in systolic and diastolic blood pressure between the two groups (p < 0.05). The results confirm that catgut embedding can influence serum NO concentration and blood pressure in essential hypertension patients.

    Specific antiserum was raised in white New Zealand rabbits using 18-hydroxydeoxycorticosterone-3-oxime-BSA complex as antigen. The urinary free 18-OH-DOC was estimated after dichloromethane extraction and separation in one paper chromatographic system (propylene glycol/toluene). The mean 18-OH-DOC excretion value (+-S.D.) in normal subjects was 0.861+-0.527 μg/24 h (n=23). ACTH produced a 25-fold increase in the excretion of free 18-OH-DOC. Dexamethasone suppressed the values to the lower range of sensitivity. 32% of patients of essential hypertension showed a moderate increase in the free urinary 18-OH-DOC values. The mean value (+-S.D.) in the low renin hypertension group was 2.50 +- 1.49 μg/24 h (n=19), in the normal renin patient group 1.84 +- 1.32 μg/24 h (n=38), and in the group with elevated plasma renin 1.61 +- 1.22 μg/24 h (n=8). The difference between controls and the hypertensive groups was statistically significant. Among the different hypertensive groups significant differences could not be calculated. (Auth.)

    Full Text Available Research objective was investigating arterial wall stiffness in patients with hypertension at young age and assessing the relationship between subclinical target organs damage and ambulatory blood pressure monitoring (ABPM parameters. 30 male patients aged 18-35 years with essential hypertension stage I and II, hypertension 1 and 2nd grade were surveyed. The examination included general clinical methods, echocardiography, ABPM and suprasystolic sfigmography. It was found that the pulse wave velocity (PWVao (r = 0,557 p <0,01, central aortic blood pressure (SBPao (r = 0,492 p <0,01 and augmentation index (AIxao (r = 0,489 p <0.01 significantly increased with the pa¬tients’ age. Abdominal obesity (r = 0,566 p <0,01 and BMI (r = 0,599 p <0,01 impacted on the PWVao acceleration. Increasing of the left ventricular mass index (LVMI is highly associated with SBPao (r = 0,506 p <0,05 and PWVao (r = 0,434 p <0,05. According to ABPM the most significant correlation with arterial wall stiffness parameters demon¬strated diastolic blood pressure (DBP daytime level (AIxao (r = 0,418 p <0,01, with PWVao (r = 0,699 p <0.01 and SBPao (r = 0,695 p <0,01. Thus, age, excessive body weight and obesity should be considered as unfavorable factors that worsen arterial wall stiffness in patients with hypertension at the age before 35 years. Increase of DBP levels especially during the day causes maximum negative impact on the arterial wall stiffness parameters according to ABPM. Increased SBPao and PWVao in patients with hypertension at a young age are associated with increased left ventricular mass index.

    Full Text Available Hypertension is the major risk factor for stroke, and genetic factors contribute to its development. Inflammation has been hypothesized to be the key link between blood pressure elevation and stroke. We performed an analysis of the association between inflammatory mediator gene polymorphisms and the incidence of stroke in patients with essential hypertension (EH. The study group consisted of 625 individuals (296 patients with noncomplicated EH, 71 hypertensive patients with ischemic stroke, and 258 control subjects. Both patients and controls were ethnic Tatars originating from the Republic of Bashkortostan (Russian Federation. The analysis has shown that the risk of ischemic stroke was associated with the CXCR2 rs1126579 polymorphism. Our results indicate that among patients with EH, the heterozygous genotype carriers had a higher risk of stroke (OR = 1.72, 95% CI 1.01-2.92, whereas the CXCR2*C/C genotype was protective against stroke (OR = 0.32, 95% CI 0.12-0.83. As shown by the gene-gene interaction analysis, the CXCR2 rs1126579 polymorphism was also present in all genotype/allele combinations associated with the risk of stroke. Genetic patterns associated with stroke also included polymorphisms in the CCL2, CCL18, CX3CR1, CCR5, and CXCL8(IL8 genes, although no association between these loci and stroke was detected by individual analysis.

    Full Text Available Blood pressure (BP has been identified as a risk factor for various health disorders, including stroke onsets. Hypertension is one of the crucial health problem among adult Ukrainian. Due to the importance of elevated BP in stroke causality, BP measurement remains critical. However, it is limited information about value in clinical practice of ambulatory blood pressure monitoring (ABPM data in hypertensive patients with inadequately controlled BP with acute stroke compared with those individuals who has no vascular onset. The aim of the study was to determine ABPM parameters in essential hypertensive patients with ischaemic hemisphere stroke. Materials and methods. A total of 114 study participants were analyzed (mean age 62 (56;72 years, 40 % women. We divided them into two groups according to the level of 24-h systolic BP (SBP and diastolic BP (DBP, and the results of clinical examination. The first group (n=83 were inadequately controlled essential hypertensive individuals with high systolic or/and diastolic BP level according to the ABMP results, and the second one (n=31 were EH patients with an acute hemispheric ischaemic stroke (IS. Diagnosis of stroke was confirmed with clinical examination and computed tomography scan or magnetic resonance imaging results, and ABPM was conducted in 4.2±2.3 days after the stroke onset. Results. We had statistician difference (p<0.001 between groups of such parameters, as average SBP (diurnal, daytime, nighttime; diurnal pulse BP; SBP load (p<0.05; the diurnal AASI (p<0.05; circadian rhythm of DBP (p<0.05. No differences were found between the groups in morning surge calculated as speed and amplitude of the BP climbed in morning hours both for SBP (P=0.422 and P=0.395, respectively and DBP (P=0.860 and P=0.337, respectively. Conclusion. In the present study, we evaluated the ABPM parameters in inadequately controlled essential hypertensive individuals with and without acute ischaemic hemispheric stroke

    Full Text Available The objective of the present study was to identify disturbances of nitric oxide radical (·NO metabolism and the formation of cholesterol oxidation products in human essential hypertension. The concentrations of·NO derivatives (nitrite, nitrate, S-nitrosothiols and nitrotyrosine, water and lipid-soluble antioxidants and cholesterol oxides were measured in plasma of 11 patients with mild essential hypertension (H: 57.8 ± 9.7 years; blood pressure, 148.3 ± 24.8/90.8 ± 10.2 mmHg and in 11 healthy subjects (N: 48.4 ± 7.0 years; blood pressure, 119.4 ± 9.4/75.0 ± 8.0 mmHg.Nitrite, nitrate and S-nitrosothiols were measured by chemiluminescence and nitrotyrosine was determined by ELISA. Antioxidants were determined by reverse-phase HPLC and cholesterol oxides by gas chromatography. Hypertensive patients had reduced endothelium-dependent vasodilation in response to reactive hyperemia (H: 9.3 and N: 15.1% increase of diameter 90 s after hyperemia, and lower levels of ascorbate (H: 29.2 ± 26.0, N: 54.2 ± 24.9 µM, urate (H: 108.5 ± 18.9, N: 156.4 ± 26.3 µM, ß-carotene (H: 1.1 ± 0.8, N: 2.5 ± 1.2 nmol/mg cholesterol, and lycopene (H: 0.4 ± 0.2, N: 0.7 ± 0.2 nmol/mg cholesterol, in plasma, compared to normotensive subjects. The content of 7-ketocholesterol, 5alpha-cholestane-3ß,5,6ß-triol and 5,6alpha-epoxy-5alpha-cholestan-3alpha-ol in LDL, and the concentration of endothelin-1 (H: 0.9 ± 0.2, N: 0.7 ± 0.1 ng/ml in plasma were increased in hypertensive patients. No differences were found for ·NO derivatives between groups. These data suggest that an increase in cholesterol oxidation is associated with endothelium dysfunction in essential hypertension and oxidative stress, although ·NO metabolite levels in plasma are not modified in the presence of elevated cholesterol oxides.

    The aim of the study was to evaluate the vasomotor activity of skin precapillary arterioles, depending on the condition of blood outflow from the capillary bed in patients with essential arterial hypertension (AH). The study included 30 normotensive subjects (NT) and 63 patients with AH, who were tested with a laser Doppler flowmetry with wavelet analysis of blood flow oscillations on the right forearm and ambulatory blood pressure monitoring (ABPM) on the left shoulder. Antihypertensive therapy was stopped for all patients 14 days prior to the experiment or AH was diagnosed for the first time. The hypertensive patients were divided into 2 groups, depending on the amplitude of the respiratory blood flow oscillations in skin microvessels. The first group included 30 patients without blood outflow violations of the capillary bed (AHVN), the second group consisted of 33 patients with various intensity of functional disorders in venular sector of microvasculature (AHVS). If the value of the amplitude of blood flow oscillations can be related to the tone" definition, then AHVN patients have a significant increase in neurogenic component of vascular tone (phypertensive patients can have significant differences in the functional state of microvessels. The assessment of the initial skin microvasculatory regulatory mechanism status could potentially be useful for individual choice of antihypertensive therapy. Copyright © 2014 Elsevier Inc.

    To investigate the significance of the electrocardiographic (ECG) pattern of left ventricular hypertrophy and strain, two groups of asymptomatic patients with essential hypertension were compared. The patients were similar in terms of age, smoking habit, serum cholesterol and blood pressure levels, but differed in the presence (Group I, n = 23) or absence (Group II, n = 23) of the ECG pattern of left ventricular hypertrophy and strain. Group I patients had significantly more episodes of exercise-induced ST segment depression (14 versus 4, p less than 0.05) and reversible thallium perfusion abnormalities (11 of 23 versus 3 of 23, p less than 0.05) despite similar exercise capacity and absence of chest pain. Nonsustained ventricular tachycardia was detected on 24 h ambulatory ECG monitoring in two patients in Group I, but no patient in Group II. Coronary arteriography performed in 20 Group I patients demonstrated significant coronary artery disease in 8 patients. This study has shown that there is a subgroup of hypertensive patients with ECG left ventricular hypertrophy and strain who have covert coronary artery disease. This can be detected by thallium perfusion scintigraphy, and may contribute to the increased risk known to be associated with this ECG abnormality

While a combination of telmisartan and a calcium channel blocker is often used to achieve a target BP level, the metabolic effects of this drug combination remain unclear. Therefore, this study evaluated the metabolic effects of telmisartan plus nifedipine controlled release (CR therapy, in hypertensive patients without metabolic disease.Methods: Sixteen patients with essential hypertension, who had not undergone antihypertensive therapy in the previous 6 months, were studied. Patients were initiated on telmisartan (40 mg/day. If their office BP was not reduced to 140/90 mmHg after 6 weeks, nifedipine CR (20–40 mg per day was added for 18 weeks. The other patients whose BP had achieved the target of 140/90 mmHg, continued only telmisartan.Results: Telmisartan reduced BP (174 ± 13/92 ± 10 to 143 ± 22/78 ± 11 mmHg; P < 0.01 at 6 weeks in 16 patients, but eight patients did not achieve target BP levels and required addition of nifedipine. Telmisartan also resulted in a reduction in the homeostatic model assessment of insulin resistance (HOMA-IR (1.30 ± 0.65 to 1.10 ± 0.42; P < 0.05 at 6 weeks, but did not affect adiponectin or leptin levels.

    Full Text Available Vascular disorders play a significant role in the development of dystrophic inflammatory process. There is a direct correlation between the degree of damage to blood vessels in the jaw and a depth of the destructive process in periodontal tissue. A certain role is played by endogenous factors, such as: age, vitamin deficiency, diabetes mellitus, essential hypertension and others. Clinical and epidemiological studies using pathological techniques showed significant changes in vascular wall of the artery in the periodontium, the interdental artery in particular.  Atherosclerosis, essential hypertension and periodontal pathology were proven to occur in individuals older than 40 years. The objective of the research was to determine periodontal tissue status in patients with stage II hypertension and generalized periodontitis of II degree of severity. Materials and methods. The study involved 36 patients with stage II hypertension and generalized periodontitis of II degree of severity (the main group. The patients’ age ranged from 35 to 54 years. The control group included 10 patients of corresponding age without generalized periodontitis and somatic pathology. To assess the status of periodontal tissues, we applied the Papillary-Marginal-Attached Index and the Community Periodontal Index of Treatment Needs. When diagnosing periodontal disease, the classification of M.F. Danilevskyi was used. Results. The analysis of the indicators of the Community Periodontal Index of Treatment Needs index showed the following results: in patients of the main group, the index was 2.38±0.07 points (p<0.001 pointing out a need for a course of professional oral hygiene. In patients of the control group, the index was 0.5±0.17 points indicating that there was no need for treatment, however, there was a need for improving oral hygiene.

    Objective: To explore the relationship of vascular endothelial marker and endothelium-dependent vasodilatation in patients with essential hypertension (EH). Methods: Plasma endothlium (ET-1) (with RIA) and von Willber factor (vWF)(with ELISA) levels were measured both before and after 12 wks' treatment in 56 patients with essential hypertension and 32 controls. The brachial artery endothelium-dependent vasodilatation function was examined with high resolving color doppler ultra-sonography. The 56 patients with EH were of two groups A. high and very high risk, n=26 B. low and moderate risk, n=30. Results: Plasma levels of ET-1, vWF in patients with EH as a whole were significantly higher than those in controls group [(53.3±16.2)pg/ml vs(42.5±8.5)pg/ml, (158.2±28.6)% vs(130.6±35.2)%], endothelium-dependent vasodilatation function wasmuch reduced in patients with EH(7.5±4.2)% vs controls(12.3±4.3)%. Among the patients, values in Group A were significantly different from those in Group B. After treatment for 12 weeks, plasma ET-1 and vWF and endothelium-dependent vasodilatation function were significantly improved. There was negative correlation between vascular endothelial marker levels and endothelium-dependent vasodilatation function. Conclusion: The endothelium-dependent vasodilatation function was impaired and plasma ET-1 and vWF levels were increased in patients with EH, the endothelial dysfunction was closely associated with the risk level of EH. Vascular endothelial markers were useful indicators for evaluation of the endothelium-dependent vasodilatation function. (authors)

  5. Effects of acute and chronic exercise in patients with essential hypertension: benefits and risks.

    The importance of regular physical activity in essential hypertension has been extensively investigated over the last decades and has emerged as a major modifiable factor contributing to optimal blood pressure control. Aerobic exercise exerts its beneficial effects on the cardiovascular system by promoting traditional cardiovascular risk factor regulation, as well as by favorably regulating sympathetic nervous system (SNS) activity, molecular effects, cardiac, and vascular function. Benefits of resistance exercise need further validation. On the other hand, acute exercise is now an established trigger of acute cardiac events. A number of possible pathophysiological links have been proposed, including SNS, vascular function, coagulation, fibrinolysis, and platelet function. In order to fully interpret this knowledge into clinical practice, we need to better understand the role of exercise intensity and duration in this pathophysiological cascade and in special populations. Further studies in hypertensive patients are also warranted in order to clarify the possibly favorable effect of antihypertensive treatment on exercise-induced effects. © American Journal of Hypertension, Ltd 2014.

    To find out a convenient and reliable method of detecting low renin status, we employed intravenous furosemine injection as a stimulatory maneuver. The results thus obtained were compared with those from the postural stimuli and basal plasma renin activity (PRA) in relation to sodium excretion. Intravenous furosemide test was performed in 66 control subjects and 44 patients with essential hypertension. The results were as follow; 1) Mean PRA in control subjects rose from 2.5+-1.95 ng/ml/hr (basal) to 4.5+-2.51, 5.2+-2.49 and 4.2+-2.44 ng/ml/hr at 1, 2 and 3hrs after IV injection. One-hour response is more convenient in clinical practice. 2) Postural stimuli by assuming an upright posture for 3hrs gave rise to considerable increase in PRA (4.0+-2.92 from 2.4+-1.85), but we found it less convenient than stimulation with furosemide. 3) The increase in PRA was much less marked in patients with essential hypertension as a whole (2.9+-2.75). Hyporesponsiveness to furosemide stimuli was found in 34.1%. Of these hyporesponders, a third had a normal basal PRA, indicating the need for this kind stimulatory procedure. 4) Younger age group showed greater renin responsiveness than older age group after furosemide stimuli. Likewise mean age of low renin patients (52.9+-5.38 years old) was significantly higher than that of high and normal renin patients (44.1+-13.78 years old). (author)

    To study the circulating humoral factor modifying transmembrane sodium transport, plasma was obtained from 12 patients with essential hypertension (EH) fed a high sodium diet (NaCl 15 to 17 g/d) for seven days and thereafter a low sodium diet (NaCl 2 to 3 g/d) for seven days. Ouabain-sensitive 86 Rb+ influx into the red blood cells (RBC) obtained from a healthy subject, and incubated with the plasma obtained during the high sodium diet was significantly lower than that incubated with the plasma obtained during the low sodium diet (3.74 +/- 0.26 v 3.97 +/- 0.30 nmol/10(8) cells, P less than .05). The changes in mean blood pressure from the high to low sodium diet showed a significant positive correlation with the changes in the ouabain-sensitive Rb influx into RBC in the plasma from the high to low sodium diet. These results suggest that a humoral factor modifying the sodium pump might be altered by sodium balance in EH, especially in salt-sensitive hypertension

    To evaluate the relationship between blood pressure control and the progression of brain atrophy in the elderly, patients with essential hypertension and brain atrophy were longitudinally evaluated using computerized tomography (CT). The study evaluated 48 patients with essential hypertension aged 46-78 years, and 30 sex- and age-matched normotensive control subjects. The extent of brain atrophy as determined by caudate head index (CHI), the inverse cella media index (iCMI), and Evans` ratio (ER) was estimated twice at an interval of 5-9 years (mean, 6.9 years). The mean annual increases in CHI ({Delta}CHI), iCMI ({Delta}iCMI), and ER ({Delta}ER) were evaluated. Mean blood volume in the common carotid artery (BF) and the decrease in BF per year ({Delta}BF) were also determined. The {Delta}CHI, {Delta}iCMI, and {Delta}ER increased with age in the hypertensive subjects as well as the control group across all age groups evaluated. The {Delta}CHI, {Delta}iCMI, and {Delta}ER were significantly greater in the patients with essential hypertension in their 50s as compared with the controls. In patients with essential hypertension aged 65 years or older, the {Delta}CHI, {Delta}iCMI, and {Delta}ER were significantly lower in the group in whom the blood pressure was controlled within the range of borderline hypertension than the groups in which it was controlled in the range of normal or mild hypertension. In the younger patients under the age of 65 with essential hypertension, blood pressure control did not affect the {Delta}CHI, {Delta}iCMI, and {Delta}ER. The {Delta}CHI, {Delta}iCMI, and {Delta}ER were significantly correlated with {Delta}BF in both groups. These findings indicate that control of systolic blood pressure within the range of borderline hypertension may delay the progression of brain atrophy in elderly patients with essential hypertension.

    While exercise therapy is established as an appropriate treatment for essential hypertension, its economic profile has not been fully evaluated. The purpose of this study is to evaluate cost and effectiveness in comparison with drug therapy. The study subjects were hypertensive patients under treatment at an outpatient clinic. Fifty-seven were selected on a non-randomized manner for exercise therapy and the same number of patients was chosen for drug therapy after matching age, sex, medication and complications. The following data were collected during three months of intervention. 1) Effectiveness: Change of systolic blood pressure before and after the intervention. 2) Cost: equipment, personnel expenses for exercise therapy and fees for health check-ups (exercise therapy); fees for consultation, laboratory examination and medications (drug therapy), 3) Cost-effectiveness: cost per 1 mmHg systolic blood pressure reduction. We evaluated the variance of cost-effectiveness by controlling the number of program participants, personnel expenses, and equipment expenses of exercise therapy. We also simulated how the cost-effectiveness of exercise therapy would improve by modifying the number of exercise participants, personnel and equipment expenses. The cost-effectiveness per 1 mmHg systolic blood pressure reduction was yen 11,268 for exercise therapy and yen 2,441 for drug therapy. Extending program facilities and increasing the number of participants would improve the cost-effectiveness of exercise therapy, but there were limitations to how far this could be achieved in the hospital setting. Differences in cost-effectiveness between exercise and drug therapies are attributed to differences in personnel expenses. Although they could be reduced by managerial effort of the hospital to some extent, outsourcing of exercise therapy to community-based facilities should be considered.

    To evaluate whether endothelium-dependent (nitric oxide-mediated) dilation of the brachial artery (BA) is impaired in patients being treated for essential hypertension (EH), and whether this abnormality can be detected in normotensive offspring of subjects with EH (familial trait, FT); and to investigate the interrelationship between flow-mediated vasodilation (FMD) and hyperinsulinaemia/insulin resistance. Cross-sectional study. Angiology department at a teaching hospital. The study encompassed 172 subjects, of whom 46 were treated hypertonics aged 40-55 (49) years, and 44 age-matched, normotensive volunteers as controls. We also investigated 41 normotonics with FT aged 20-30 (25) years and 41 age-and sex-matched controls without FT. Using high-resolution ultrasound, BA diameters at rest, during reactive hyperaemia (endothelium-dependent dilation) and after sublingual glyceryl trinitrate (GTN) application (endothelium-independent dilation) were measured. In hypertonics FMD was significantly lower than in controls [2.4 (2.9) vs. 7.4 (2.5)%; P < 0.00005], as was GTN-induced dilation [12.1 (4.3) vs. 16.1 (4.6)%; P=0.0007]. In subjects with FT, FMD was also decreased compared with the control group [5.8 (4.1) vs. 10.0 (3.0)%; P < 0.00005]. The response to GTN was comparable in both groups of young subjects. FMD was negatively related to insulin concentration in all subjects studied (P < 0.00005). In treated patients with EH, flow-mediated dilation of the BA as well as endothelium-independent dilation are decreased. In individuals with FT the endothelial function of the peripheral arteries is also altered in the absence of elevated blood pressure. Endothelial dysfunction is related to hyperinsulinaemia/insulin resistance, which could be one of the pathogenetic determinants of EH and its complications.

    Leptin is a product of the ob gene and is secreted by the adipose tissue. It takes part in regulation of nervous, cardiovascular, endocrine system and renal functions. The aim of this study was to assess the influence of short term moderate exercise on serum leptin levels in patients with arterial hypertension. The study group consisted of 34 patients with essential hypertension: 15 women (48.9 +/- 12.1 years old) and 19 men (43.5 +/- 14.6 years old). There were 7 patients with stage I of hypertension, 17 patients with stage II of hypertension and 10 patients with stage III of hypertension. The blood samples were taken before and after the exercise test. Serum leptin levels were assessed by radioimmunoassay. Serum leptin levels were significantly higher in women then in men. The logarithm of serum leptin levels after the exercise was significantly lower than before (0.8 +/- 0.4 and 0.9 +/- 0.5 respectively). The moderate, short term exercise decreases serum leptin levels in the hypertensive patients.

    Aim: To assess the relationship between the volume of the carotid bodies (V rCB+lCB ) examined by means of computed tomography angiography (CTA) and blood pressure variability and pulse pressure (PP) in 24-hour ambulatory blood pressure monitoring (ABPM) in patients with essential hypertension. Materials and methods: A group of 52 patients with essential hypertension was examined (mean age: 68.32±12.31 years), the sizes of carotid bodies were measured by means of carotid artery CTA, and 24-hour ABPM was carried out. The 24-hour ABPM established systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), PP, SBP variability (SBPV), and DBP variability (DBPV). Results: SBP, MAP, and SBPV were significantly higher in the group of hypertension patients with V rCB+lCB equal to or above the median than in the group of hypertension patients with V rCB+lCB less than the median, as well as in the group of hypertension patients with oversized carotid bodies, than in the group of hypertension patients with normal V rCB+lCB . Moreover, the PP was statistically significantly higher in the group of hypertension patients with V rCB+lCB equal to or above the median than in the group of hypertension patients with V rCB+lCB less than the median. The existence of statistically significant positive linear relationships was revealed between V rCB+lCB and SBP, PP, and SBPV. A higher body mass index, older age, smoking, and higher V rCB+lCB are independent risk factors increasing SBPV in the research group. Conclusion: A positive relationship between the size of the carotid bodies and variability of the SBP and PP is observed in patients with essential hypertension. - Highlights: • Purpose. Determination of the relationships: V rCB+lCB vs. BPV and V rCB+lCB vs. PP. • Positive linear correlations were documented between V rCB+lCB and SBP, PP and SBPV. • Higher BMI, age, V rCB+lCB and smoking are independent risk factor of increased SBPV.

    This study aimed to assess the cognitive functions and cerebral blood flow measured with arterial spin labeling (ASL) and their possible correlations with vascular age in untreated middle-aged patients with grade 1-2 essential arterial hypertension (EAH). We examined 73 subjects aged 40-59 years (33 with EAH and 40 healthy volunteers [controls]). Neuropsychological assessment included Montreal Cognitive Assessment (MoCA), Trail Making test (part A and part B), Stroop Color and Word Test, verbal fluency test (phonemic verbal fluency and semantic verbal fluency), 10‑item word list learning task. All subjects underwent brain MRI. MRI protocol included ASL. Vascular age was calculated by two techniques - using Framingham Heart Study risk tables and SCORE project scales. Patients with EAH had lower performance on phonemic verbal fluency test and lower mean MoCA score (29.2±1.4 vs. 28.1±1.7 points) compared to controls (13.4±3.2, р=0.002; 29.2±1.4, p=0.001, respectively). White matter hyperintensities (WMH) were present in 7.5 % controls and in 51.5 % EAH patients (р=0.0002). Cerebral blood flow (CBF) in EAH patients was lower in both right (39.1±5.6 vs. 45.8±3.2 ml / 100 g / min) and left frontal lobes of the brain (39.2±6.2 и 45.2±3.6 ml / 100 g / min, respectively) compared to controls (р.

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

    It has been suggested that in animal models, red wine may have a protective effect on the vascular endothelium. However, it is not known whether this effect is also present in human small vessels and whether it is specific for certain wines. The objective of this study is to compare the vasodilator effects in subcutaneous small resistance arteries of wines with different flavonoid content as well as of ethanol vs. wines in normotensive (NT) subjects and in patients with essential hypertension (EH). Twenty-six EH and 27 NT were included in the study. Subcutaneous small resistance arteries were dissected and mounted on a micromyograph. Then we evaluated vasodilator responses as concentration-response curves (20, 30, and 50 microl) to the following items: (i) a red wine produced in small oak barrels ("en barrique": EB) (Barolo Oberto 1994), (ii) a red wine produced in large wood barrels (LB) (Barolo Scarzello 1989), (iii) a red wine produced in steel tanks (Albarello Rosso del Salento 1997), and (iv) a white wine produced in steel tanks in the presence or absence of an inhibitor of the nitric oxide (NO) synthase (L-NMMA 100 micromol/l). A dose-dependent vasodilator effect of red wines (particularly EB and LB) was detected in both NT and HT. The observed response was not reduced after preincubation with L-NMMA. Our results suggest red wines are more potent vasodilator than ethanol alone, possibly depending on the content of polyphenols or tannic acid. HT show similar responses compared with NT, indicating that red wine is not harmful in this population.

    Left ventricular hypertrophy (LVH) is one of the more important risk factors for sudden death. There are multiple factors for development of LVH in patients with hypertension. Sympathetic nervous system may play a key role causing afterload increase and neurohumoral mechanisms activation. The aim of the study was to determine beta-adrenergic receptors density and its relations to left ventricular mass in hypertensive subjects. The study was carried out in 63 patients (23 women and 40 men), mean age 43.3 +/- 11.6 yrs with primary hypertension: stage I--42 pts and stage II--21 pts. The control group consisted of 26 healthy persons matched for age and sex. We evaluated the density of beta-adrenergic receptors using 125I-cyanopindolol radioligand labeling method. Left ventricular dimensions were assessed by echocardiography (Hewlett-Packard 77010 CF) and left ventricular mass index (LVMI) was calculated. Systolic and diastolic blood pressure and LVMI was significantly higher in hypertension group 156.7 +/- 12.5 vs. 119.8 +/- 8.8 mmHg, p < 0.0001, 95.9/5.5 vs. 78.8 +/- 6.5 mmHg, p < 0.0001, 126.5 +/- 41.9 vs. 93.1 +/- 19.9 g/m2, p < 0.001 respectively. Beta-adrenergic receptors density was 40.7 +/- 29.9 fmol/ml in the hypertensive vs. 37.2 +/- 17.8 fmol/ml in control group (p = NS). There was no correlation between beta-adrenergic receptors density and LVMI. There was a statistically significant positive correlation between LVMI and systolic and diastolic blood pressure (r = 0.44, p < 0.05; r = 0.60, p < 0.01 respectively). 1. Beta-adrenergic receptors density was unchanged in patients with hypertension and did not correlate with LVMI. 2. A high positive correlation between blood pressure values and LVMI, but only in stage II hypertension was revealed.

    To evaluate fundus autofluorescence (FAF) changes in patients with chronic essential hypertension (HTN). In this case-control study, 35 eyes of 35 patients with chronic essential HTN (lasting >5 years) and 31 eyes of 31 volunteers without history of HTN were included. FAF pictures were taken from right eyes of all cases with the Heidelberg retina angiography and then were assessed by two masked retinal specialists. In total, FAF images including 35 images of hypertensive patients and 31 pictures of volunteers, three apparently abnormal patterns were detected. A ring of hyper-autofluorescence in the central macula (doughnut-shaped) was observed in 9 (25.7%) eyes of the hypertensive group but only in 2 (6.5%) eyes of the control group. This difference was statistically significant (P = 0.036) between two groups. Hypo- and/or hyper-autofluorescence patches outside the fovea were the other sign found more in the hypertensive group (22.9%) than in the control group (6.5%); however, the difference was not statistically significant (P = 0.089). The third feature was hypo-autofluorescence around the disk noticed in 11 (31.4%) eyes of hypertensive patients compared to 8 (25.8%) eyes of the controls (P = 0.615). A ring of hyper-autofluorescence in the central macula forming a doughnut-shaped feature may be a FAF sign in patients with chronic essential HTN.

    Objective: To investigate the changes of serum levels of insulin-like growth factor II (IGF II) and adrenomedullin (ADM) in patients with essential hypertension. Methods: Serum IGF II and ADM levels were measured in 62 cases of hypertension and 40 controls with RIA. Results: Serum IGF II and ADM levels were significantly bigger in hypertensive patients than those in the controls (t = 4.454, p < 0.01; t = 3.992, p < 0.01). The serum IGF II level was significantly positively correlated to the serum ADM levels (r = 0.379, p < 0.05) and both were significantly positively correlated to the mean arterial pressure (r = 0.346, r = 0.353, p < 0.05) but not with BMI. Serum ADM levels increased gradually as the disease progressed from stage I to stage III (p < 0.05) with levels in stage III markedly higher than those in stage I (p < 0.01). In EH patients with heart and/or brain and/or renal complications the serum ADM levels were significantly higher than those in EH patients without complications (t = 2.050, p < 0.05). Such differences did not exist in the case of IGF II. Conclusion: Serum IGF II and ADM levels were increased markedly in hypertensive patients. These two factors were mutually positively correlated and both were positively correlated to mean arterial pressure. ADM levels increased gradually as the disease progressing but IGF II levels remained stable

    The aim of the study was to assess the association of serum uric acid levels with microalbuminuria -urinary albumin excretion (UAE)> or = 30mg/24h-. Cross-sectional study in 429 (220 women) hypertensive, non diabetic, never treated patients (mean age: 47 years) with glomerular filtration rate > or =60ml/min/1.73m(2). The prevalence of microalbuminuria was 20.5%; 18% had hyperuricemia and 47% fulfilled the criteria for metabolic syndrome (MS). Baseline UAE correlated in the unvaried analysis to diastolic blood pressure, waist circumference, high-density lipoprotein cholesterol and uric acid. In multiple linear regression models, only MS (beta=0.113; p=0.03), and serum uric acid values (beta=0.04; p=0.05) were independently associated with logUAE, after adjustment for age and sex. Hyperuricemia (serum uric acid level > or =7.0mg/dl for men and > or =6.5mg/dl for women; odds ratio=2.18; 95% confidence interval, 1.21-3.92; p=0.010), and MS (odds ratio=2.16; 95% confidence interval, 1.32-3.53; p=0.002) were independently associated with a higher risk of microalbuminuria in multiple logistic regression analyses. The prevalence of microalbuminuria was 45.8% in patients with coexistent MS and hyperuricemia, as compared to 13.6% in hypertensive patients without it (p<0.001). In patients with concomitant MS and hyperuricemia the probability of being microalbuminuric was 3.7 times higher than in patients without those factors. Serum uric acid level is associated with microalbuminuria. Coexistence of MS and hyperuricemia in hypertensive patients increases almost 4 times the odds of being microalbuminuric.

    Objectives Thiazide diuretics are one of the first choice antihypertensives but not optimally utilised because of concerns regarding their adverse effects on glucose metabolism. The Diuretics In the Management of Essential hypertension (DIME) study was designed, for the first time, to assess the risk for type 2 diabetes mellitus in patients with essential hypertension during antihypertensive treatment with low-dose thiazide diuretics compared to those not treated with diuretics. Design Multicentre, unblinded, pragmatic, randomised, controlled trial with blinded assessment of end points and intention-to-treat analysis that was started in 2004 and finished in 2012. Setting Hypertension clinics at 106 sites in Japan, including general practitioners’ offices and teaching hospitals. Participants Non-diabetic patients with essential hypertension. Interventions Antihypertensive treatment with low-dose thiazide diuretics at 12.5 mg/day of hydrochlorothiazide or equivalent (Diuretics group) or that without thiazide diuretics (No-diuretics group). Main outcome The primary outcome was new onset of type 2 diabetes diagnosed according to WHO criteria and the criteria of Japanese Society of Diabetes. Results 1130 patients were allocated to Diuretics (n=544) or No-diuretics group (n=586). Complete end point information was collected for 1049 participants after a median follow-up of 4.4 years. Diabetes developed in 25 (4.6%) participants in the Diuretics group, as compared with 29 (4.9%) in the No-diuretics group (HR 0.93; 95% CI 0.55 to 1.58; p=0.800). Conclusions Antihypertensive treatment with thiazide diuretics at low doses may not be associated with an increased risk for new onset of type 2 diabetes. This result might suggest safety of use of low doses of thiazide diuretics. Trial registration number ClinicalTrials.gov NCT00131846. PMID:25031188

    To estimate the possibility of predicting the presence and severity of coronary atherosclerosis from arterial stiffness characteristics and augmentation index (AIx) in patients with essential hypertension (EH) obtained under outpatient conditions. The general clinical examination of 15 patients aged 30-70 yr with EH was supplemented by measuring blood glucose and creatinine levels, the lipid status (LWLP, HDLP, TG), duplex scanning of carotid arteries, and evaluation of arterial stiffness by pulsed wave contour analysis. AIx and age were independent risk factors of coronary atherosclerosis in patients with EH and severity of its manifestations. AIx values over 25% were with high specificity (over 85%) associated with atherosclerotic lesions.

    Objective: To study the effects of changes of neuropeptide Y (NPY) and neurotensin (NT) concentrations in plasma and their ratio imbalance on the incidence of essential hypertension (EH). Methods: NPY and NT in plasma in 176 patients with EH were measured with radioimmunoassay (RIA). Results: NPY in the EH patients was higher than that in the normal subjects (P<0.01), and went up with the aggravation of the patients' condition (P<0.01). NT in the EH patients was lower compared with the normal subjects (P<0.01), and went down with the aggravation of the patients' condition (P<0.01). NPY/NT in the EH patients was higher than that in the normal subjects (P<0.01), and was accordant with patients' condition. Conclusion: NPY and NT are involved in the incidence of EH. The ratio imbalance of NPY/NT may be one of the factors causing EH. (authors)

    To evaluate efficacy and safety of 60mg and 120mg Fimasartan (FMS) alone or combined with 12.5mg hydrochlorothiazide (HCTZ) in a Mexican population. A six month, treat-to-target, open study was conducted on subjects with grade 1-2 hypertension. The subjects were initially treated with 60mg FMS once daily. In week 8, those with Diastolic Blood Pressure (DBP) <90mmHg continued on the same FMS dose during the rest of the study, while those with DBP ≥90mmHg were randomised to either 120mg FMS or 60mg FMS + 12.5mg HCTZ once daily. In week 12, randomised subjects with DBP ≥90mmHg received 120mg FMS+12.5mg HCTZ, while those achieving target continued with their assigned treatment until the end of the study. FMS 60mg (n=272) decreased both DBP and Systolic Blood Pressure (SBP) by 11.3±8.9 (p<.0001) and 16.0±14.1 (p<.0001)mmHg, respectively, with 75.4% of subjects reaching the treatment target. Subjects assigned to FMS 120mg, FMS 60mg+HCTZ 12.5mg, or FMS 120mg+HCTZ 12.5mg once daily, showed significant reductions in DBP and SBP with their assigned treatment. At the end of the study, 237/272 subjects (87.1%) achieved a DBP<90mmHg and an SBP<140mmHg. The most frequently reported adverse reactions included headache (3.7%), dry mouth (1.1%), transient liver enzyme increase (1.1%), and dizziness (0.7%). Fimasartan is safe and effective in Mexican subjects with grade 1-2 essential hypertension. Copyright © 2017 Instituto Nacional de Cardiología Ignacio Chávez. Publicado por Masson Doyma México S.A.

    The aim of the study was to determine whether epicardial adipose tissue volume (EATV), a new cardiometabolic risk factor, is associated with circadian changes of blood pressure (BP) in patients with newly diagnosed essential hypertension. Ninety patients with newly diagnosed essential hypertension underwent ambulatory blood pressure monitoring for 24 h. EATV was measured using cardiac computed tomography. These patients were categorized into three groups according to their BP patterns (group 1, n=46, dipper hypertension, also called normal pattern; group 2, n=24, non-dipper hypertension; group 3, n=20, anti-dipper hypertension; group 2 and 3 are also called abnormal pattern). Data were collected retrospectively and compared between hypertensive patients with normal pattern and abnormal pattern. The normal pattern hypertensive patient had significant lower mean EATV and BP ((EATV, 91.3±29.4 cm3) than those of abnormal pattern patients including group 2 (EATV, 116.2±31.06cm3, EATV, 124.8±28.5cm3, PEATV with abnormal blood pressure mode was 0.500 (pEATV was elevated in newly diagnosed and untreated patients with non-dipper hypertension and anti-dipper hypertension. EATV measured by cardiac computed tomography can be used to indicate the increased risk of circadian rhythm of blood pressure.

    Blood pressure (BP) reduction is the major determinant of benefit provided by antihypertensive treatment. Although different drugs reduce peripheral BP to some extent, there may be a significant difference in their effect on central BP reduction. It has been shown that beta-blockers are efficient in reducing peripheral, but not central BP. This study was done to assess the effect of beta-1-blocker, nebivolol, in patients with essential hypertension on central aortic pressures and arterial stiffness. In this single arm, open-labeled study, 13 patients were given nebivolol, 5 mg orally once daily for 15 days. Primary outcome was change in central aortic pressure, and other measures of efficacy included changes in brachial BP, augmentation index (AIx%), AIx%@75 HR, augmentation pressure (AP), heart rate (HR), and carotid femoral pulse wave velocity (PWVcf). Nebivolol 5 mg significantly reduced central aortic pressures [systolic BP, 131.5-111.6 mmHg; diastolic BP, 96.3-81.7 mmHg; Mean Arterial Pressure (MAP), 111.3-94.0 mmHg (all PPressure (PP), 35.2-29.7 mmHg (Plost to followup. Nebivolol 5 mg demonstrated antihypertensive efficacy in patients with essential hypertension by reducing not only peripheral brachial pressures, but also significantly reducing central aortic pressures, augmentation index, and carotid femoral pulse wave velocity, which is the marker of arterial stiffness.

    Full Text Available Background. Atrial natriuretic peptide (ANP considerably influences blood pressure regulation through water and sodium homoeostasis. Several of the studies have utilized anonymous genetic polymorphic markers and made inconsequent claims about the ANP relevant disorders. Thus, we screened Insertion/Deletion (ID and G191A polymorphisms of ANP to discover sequence variations with potential functional significance and to specify the linkage disequilibrium pattern between polymorphisms. The relationships of detected polymorphisms with EH with or without Type 2 Diabetes Mellitus (T2DM status were tested subsequently. Method. ANP gene polymorphisms (I/D and A191G were specified utilizing mutagenically separated Polymerase Chain Reaction (PCR in 320 subjects including 163 EH case subjects and 157 controls. Result. This case-control study discovered a significant association between I/D polymorphisms of ANP gene in EH patient without T2DM. However, the study determined no association between G191A polymorphisms of ANP in EH with or without T2DM. In addition, sociodemographic factors in the case and healthy subjects exhibited strong differences (P<0.05. Conclusion. As a risk factor, ANP gene polymorphisms may affect hypertension. Despite the small sample size in this study, it is the first research assessing the ANP gene polymorphisms in both EH and T2DM patients among Malaysian population.

    Objective: To explore the use of cystatin C for analysing the results of renal function tests and renal blood flow study in patients with essential hypertension. Methods: The following tests were performed in 62 patients with essential hypertension and 32 controls: plasma cystatin C (with LPET), plasma ET (with RIA), four urinary sensitive parameters for detecting early renal injury i.e. urinary Alb/Cr, NAG/Cr and {alpha}-mG/Cr (with ELISA) and renal blood flow study (with Doppler). Results: The patients could be divided into two groups: Cystatin C positive (above normal value, n=23) and cystamin C negative (n=39). Plasma ET levels in cystamin C positive group were significantly higher than those in the 32 controls. Values of the four urinary parameters in the two patient groups were very significantly higher than those in the controls (p<0.01), the difference between the two patient groups was also very significant (p<0.01). Renal arterial blood flow in the two patient groups was much different from that was no significant difference between the two groups themselves. In the patients, with the decrease of GFR, Serum creatinine levels were elevated but urea nitrogen levels remained within normal limit. Conclusion: In the cystamin C negative patients, there was already marked alteration of the renal blood flow through auto-regulation. Although GFR, serum creatinine and urea nitrogen levels remained within normal range, early renal injury, especially tubular ones had been present. As the disease worsened and cystatin levels increased, there was no progressive alteration of renal blood flow. Marked deterioration of renal glomeruli and tubular functions could be detected.

    To explore healthcare disparities in rural China two years after the implementation of the Essential Public Health Service (EPHS) reform in 2009. A cross-sectional study was conducted by surveying 930 hypertension patients (HPs) from different regions in rural China in 2011. The percentages of patients using recommended four or more follow-up visits in a year were calculated by patient socio-demographic characteristics and statistically examined using chi-square and logistic regression to uncover disparities and correlated factors in EPHS use. The rates were not significantly different by age, gender, education, insurance status or income, but significantly different by region and hypertension history (p<0.01). Higher rates were also observed on patients who sought actively follow-up service at clinics, making appointment for the next follow-up with doctors, awareness of the need of follow-up, more satisfied with the follow-up services, and better medication adherence (p<0.01). There were no disparities observed among HPs in the use of follow-up services, suggesting that the reform has to some extent achieved its goal in ensuring equal access to EPHS. In this regard, regional implementation of the national policies and improvement of EPHS management at local level should be further improved.

    Full Text Available The oxidative stress state is characterized by an increase in oxygen reactive species that overwhelms the antioxidant defense; we do not know if these pathological changes are correlated with alterations in left ventricular mechanics. The aim was correlating the oxidative stress state with the left ventricular global longitudinal strain (GLS and the left ventricular end diastolic pressure (LVEDP. Twenty-five patients with essential hypertension and 25 controls paired by age and gender were studied. All of the participants were subjected to echocardiography and biochemical determination of oxidative stress markers. The hypertensive patients, compared with control subjects, had significantly (p<0.05 higher levels of oxidized proteins (5.03±1.05 versus 4.06±0.63 nmol/mg, lower levels of extracellular superoxide dismutase (EC-SOD activity (0.045±0.02 versus 0.082±0.02 U/mg, higher LVEDP (16.2±4.5 versus 11.3±1.6 mm Hg, and lower GLS (−12% versus −16%. Both groups had preserved ejection fraction and the results showed a positive correlation of oxidized proteins with GLS (r=0.386, p=0.006 and LVEDP (r=0.389, p=0.005; we also found a negative correlation of EC-SOD activity with GLS (r=-0.404, p=0.004 and LVEDP (r=-0.347, p=0.014.

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

    A study was made of the influence of the constant MKM2-1 magnets on patients suffering from essential hypertension. Continuous action of the magnetic field, created by such magnets, on the patients with stage II essential hypertension was noted to result in a decrease of arterial pressure without the occurrence of any side effects and in a simultaneous reduction of the scope of drug administration. Apart from that fact, magnetotherapy was discovered to produce a beneficial effect on the central hemodynamics and microcirculation. The use of the MKM2-1 magnets may be regarded as a feasible method of the treatment of essential hypertension patients at any medical institution.

    There is a frequent association between renal insufficiency and cardiovascular disease in patients with essential hypertension (HTN). The aim of this study was to analyze the relationship between ECG parameters and the progress of renal damage in patients with treated HTN. 109 patients with HTN had their microalbuminuria monitored over a 3-year time frame. During the last 3 months of follow-up, an ECG was recorded. Patients were divided into 3 groups according to the deterioration of their renal function: normoalbuminuria during the study period (normo-normo; n = 51); normoalbuminuria developing microalbuminuria (normo-micro; n = 29); and microalbuminuria at baseline (micro-micro; n = 29). There were no differences in presence of left ventricular hypertrophy between the 3 groups. RV6/RV5 >1 was observed more frequently as renal function declined ( p = 0.025). The 12-lead QRS-complex voltage-duration product was significantly increased in patients without microalbuminuria at baseline who went on to develop microalbuminuria ( p = 0.006). Patients who developed microalbuminuria during follow-up, with positive Cornell voltage criteria, showed a lesser degree of progression of microalbuminuria when compared with the rest of the subgroups ( p = 0.044). Furthermore, patients with microalbuminuria at baseline treated with angiotensin receptor blockers and diuretics, and positive Cornell voltage criteria, showed a higher degree of microalbuminuria compared to those with negative Cornell voltage criteria ( p = 0.016). In patients with HTN, we identified some ECG parameters, which predict renal disease progression in patients with HTN, which may permit the identification of patients who are at risk of renal disease progression, despite optimal antihypertensive pharmacotherapy.

    Sympathetic nervous system may play an important role in development and maintenance of hypertension. Its activity can be assessed by plasma levels of catecholamines, neuropeptide Y (NPY) and adrenergic receptor density. Hypertensive subjects may be more prone to reveal overactivity of sympathetic nervous system, for instance as a result of physical stress. The aim of the study was to determine the activity of sympathetic nervous system in young patients with newly recognized, untreated mild hypertension. The study was carried out in 22 patients (age 38.5 +/- 10.3 years) and 20 normotensive volunteers (age 38.5 +/- 8.6 years) as a control group, matched for sex. Density of alpha 2- and beta-adrenergic receptors using 3H-yohimbine and 125I-cyanopindolol respectively, total catecholamines and plasma renin activity using radioenzymatic assay, neuropeptide Y and aldosterone using radioimmunoassay were assessed in the blood taken in the supine position and after moderate bicycle ergometer exercise. Plasma concentration of NPY at rest did not differ between the groups, but increased significantly after exercise and was greater in hypertensive patients (p < 0.05). The density of alpha 2- and beta-adrenergic receptors at rest and after exercise in hypertensive subjects was unchanged when comparing to healthy individuals. The plasma concentrations of endogenous catecholamines, plasma renin activity and aldosterone level increase during exercise in both studied groups (p < 0.05). Aldosterone level was higher in hypertensive patients at rest (p < 0.05). There was a negative correlation between baseline aldosterone and NPY levels in hypertensive patients (r = -0.44, p < 0.05). Moderate exercise in hypertensive subjects causes the hyperactivity of sympathetic nervous system expressed as increase of NPY plasma level.

    In this multicentre, prospective, randomized, open-label, blinded-endpoint (PROBE) study, the efficacy of 12 weeks' treatment with once-daily telmisartan 40-80 mg and enalapril 10-20 mg was evaluated using ambulatory blood pressure monitoring (ABPM) in 522 patients with mild-to-moderate essential hypertension. Patients were titrated to the higher dose of study drug at week 6 if mean seated diastolic blood pressure (DBP) was > or = 90 mmHg. The primary endpoint was the change from baseline in ambulatory DBP in the last 6 h of the 24-h dosing interval after 12 weeks' treatment. Telmisartan and enalapril produced similar reductions from baseline in DBP and systolic blood pressure (SBP) over all ABPM periods evaluated (last 6 h, 24-h, daytime and night-time). Telmisartan produced a significantly greater reduction in mean seated trough DBP, measured unblinded with an automated ABPM device in the clinic, amounting to a difference of -2.02 mmHg (P ABPM device. Both treatments were well tolerated. Compared with telmisartan, enalapril was associated with a higher incidence of cough (8.9% versus 0.8%) and hypotension (3.9% versus 1.1%). Therefore, telmisartan may provide better long-term compliance and, consequently, better blood pressure control than enalapril.

    Abnormal erythrocyte Na+ transport has been reported in patients with essential hypertension and some first-degree relatives. The two major techniques now employed for estimating Na+ transport--Na+/Li+ countertransport and Na+/K+ cotransport--are rather intricate and time consuming. Furthermore, the precise nature of the transport processes being measured is not clear. We have developed a simpler, more direct technique based on measurement of 22Na+ accumulation by erythrocytes. 22Na+ uptake by red cells from patients with essential hypertension averages twice normal. Indeed, of 21 patients with essential hypertension, only 2 patients had values within the upper end of the normal range. In 12 patients with secondary hypertension and no family history of essential hypertension, erythrocyte 22Na+ accumulation was within normal limits. Control experiments indicate that our technique for estimating red cell 22Na+ uptake is highly reproducible and shows little day-to-day variation. This procedure for the assessment of erythrocyte Na+ transport should be useful in differential diagnosis and the presymptomatic identification of individuals genetically prone to essential hypertension

    Patient with arterial hypertension and no definable cause are said to have essential, primary or idiopathic hypertension. A total of 100 patients suffering from essential hypertension and 100 control subjects with almost same mean age and sex distribution were enrolled in this study. Levels of serum uric acid, total cholesterol, TG, and HDL-c were determined by enzymatic colorimetric method. Serum LDL-c and VLDL-c was calculated by using Friedewald and Wilson's formulae. The study was aimed to find out the levels of serum uric acid and lipid profile in patients with essential hypertension and to compare them with levels of normal healthy individuals. Results show increased level of serum uric acid and lipid parameters except for HDL-c, which was significantly, decreased in patients with essential hypertension as compared to the control subjects. Variations in aforementioned parameters were also observed on comparing the obese and the non-obese patients. It can be concluded from the present study that the essential hypertension is associated with abnormalities in the levels of serum uric acid and lipid profile. (author)

    To compare antihypertensive effect of fixed dose combination Hydrochlorothiazide-Amiloride and Amlodipine in patients of mild essential hypertension. After fulfilling the inclusion criteria of mild essential hypertension, defined as per recommendations of Seventh Joint National Committee (JNC 7) for treatment of Hypertension as stage 1 hypertension, systolic blood pressure (SBP) amlodipine and hydrochlorthiazide-amiloride 140-159-mmHg and Diastolic blood pressure(DBP) greater or equal to 90-99-mmHg, 100 patients were randomized into two study groups using a table of random numbers. Group 1 received tab amlodipine (5 mg) and Group 2 received tab hydrocholrthiazide-amiloride (25 mg-2.5mg). Informed written consent was taken. The patients were followed on subsequent visits (6 in total) for five months and systolic and diastolic blood pressure was recorded carefully. All the data thus obtained were processed and analyzed using SPSS version 10.0. Mean and standard deviation (SD) were calculated for age, diastolic and systolic blood pressure. In group 1 the drop in mean SBP between first and last visit was 15.42 mm Hg. In group 2 the drop in mean SBP between first and last visit was 18.34 mm Hg. In group 1, the drop in mean DBP between first and last visit was 10.08 mm Hg. In group 2 the drop in mean DBP between first and last visit was 14.65 mmHg. Mean drop in SBP of both the groups were compared with each other and found to be significantly different (P=0.003). Similarly mean drop in DBP of both the groups were compared with each other and found to be significant statistically (P=0.001). Hydrochlorothiazide-Amiloride had significantly better antihypertensive effect than Amlodipine in patients of mild essential hypertension at the end of five months therapy. (author)

    Full Text Available Background: In present study, we tried to determine significant palmar dermatoglyphic parameters in case of essential hypertensive’s in age group between 20-50 years and whether the parameters can be used for screening purpose i.e., early detection of hypertension. Method: With the use of modified Purvis Smith method, Black duplicating ink (Kores, Bombay was smeared on both hands one by one and prints will be taken by rolling the hands from wrist creases to finger tips on the roller covered with bond paper. While crystal bond paper, applied firmly over a wooden pad, was used for recording the inked epidermal ridge patterns. Rolled finger prints were recorded after applying uniform pressure on white bond paper from ulnar to radial side. Complete palm impression, including the hollow or the palm was obtained over paper. Thus one set of finger prints and palm prints was obtained. The prints obtained were immediately examined with hand-lens. Result: Right hand and left hand of the both male and female study group showed more number of arches than controls. Right hand and left hand of the both male and female study group showed more number of Radial loops than controls. The right hand and left hand of both male and female control group showed more number of ulnar loops than study group. The right hand and left hand of the male control group showed more number of Whorls than study, while in females, the right hand study group showed more number of whorls than control group and the left hand study group showed less number of Whorls as compared to control group. Conclusion: The present study indicates that there are some genetic factors which are involved in the causation of essential hypertension and it is possible to certain extent to predict from dermatoglyphics individual’s chance of acquiring essential hypertension. Like clinical history, examination and investigations, the dermatoglyphics will play an important role revealing the genetic

    Sympathetic fibers connect sphenopalatine ganglion (SPG) with the central nervous system. We aimed to study the effect of SPG block in blood pressure (BP) in never treated patients with stage I-II essential hypertension. We performed bilateral SPG block with lidocaine 2% in 33 hypertensive patients (mean age 48±12years, 24 men) and a sham operation with water for injection in 11 patients who served as the control group (mean age 51±12years, 8 men). All patients have been subjected to 24h ambulatory blood pressure monitoring prior and a month after the SBG block in order to estimate any differences in blood pressure parameters. We defined as responders to SBG block those patients with a 24h SBP decrease ≥5mmHg. We found that 24h and daytime DBP (p=0.02) as well as daytime DBP load (p=0.03) were decreased in the study group a month after SPG block. In addition, a significant response was noted in 12/33 responders (36%) regarding: a.

    Full Text Available Context: Nonadherence to therapeutic plans has been reported among hypertensive patients. Researchers have also shown that adherence to therapeutic plans improves if motivation in the form of social support is provided. There is a dearth of local studies that explore the influence of family support on treatment outcomes of hypertensive patients. Aims: The aim of the study was to determine the relationship between BP control and perceived family support in patients with essential hypertension seen at a primary care setting in Western Nigeria. Settings and Design: This was a cross-sectional hospital-based study. Subjects and Methods: Systematic random sampling technique was used in selecting 360 hypertensive respondents between April and July 2013. Data were collected through a pretested interviewer-administered questionnaire and a standardized tool, Perceived Social Support Family Scale, which measured the respondents′ level of perceived family support. Statistical Analysis Used: Statistical Package for Social Sciences (SPSS version 17.0 was used to analyze data. Results: The majority of the respondents were middle-aged (61.1% and female (59.4%. Blood pressure (BP was controlled in 46.4% of the respondents. Most of the respondents (79.4% had "strong" perceived family support. Strong perceived family support (odds ratio [OR] 4.778, 95% confidence interval [CI] =2.569-8.887 and female gender (OR 1.838, 95% CI = 1.177-2.869 were independent predictors of controlled BP. Conclusions: The proportion of hypertensive patients with optimal BP control is low in this practice setting. The positive association between BP control and perceived family support emphasizes the need for physicians to reflect on the available family support when managing hypertensive patients.

    Felodipine, a recently developed calcium channel antagonist, was administered twice daily (10 mg/day) for 1 month to 5 patients with mild to moderate essential hypertension. Its antihypertensive effect, as well as its effect on cerebral and renal blood flow, was investigated. After 1 month of therapy, sitting systolic and diastolic blood pressure were significantly decreased. The antihypertensive effect was well tolerated and sustained during the administration period. Total cerebral blood flow, as assessed by 99m Tc-hexamethyl-propyleneamine oxime, increased to 46.8±6.4 ml/100 g/min from a pretreatment level of 43.6±6.4 ml/100 g/min (P 99m Tc-diethylenetriamine pentaacetic acid, unchanged: 70.2±19.9 ml/ min before and 71.8±13.6 ml/min after. Blood viscosity and the number of blood platelet tended to decrease during treatment. There were essentially no significant changes in biochemical parameters, and no severe side effects were encountered during the administration. These results not only confirmed the safety and usefulness of felodipine as an antihypertensive agent for the treatment of essential hypertension, but also suggested that this new calcium channel antagonist may exert beneficial effects on central as well as renal hemodynamics in essential hypertensives.

    Full Text Available Background. Certain hypertension subtypes have been shown to increase the risk for cardiovascular morbidity and mortality and may be related to specific underlying genetic determinants. Inappropriate characterization of subtypes of hypertension makes efforts at elucidating the genetic contributions to the etiology of hypertension largely vapid. We report the hypertension subtypes among patients with hypertension from South-Western Nigeria. Methods. A total of 1858 subjects comprising 76% female, hypertensive, aged 18 and above were recruited into the study from two centers in Ibadan, Nigeria. Hypertension was identified using JNCVII definition and was further grouped into four subtypes: controlled hypertension (CH, isolated systolic hypertension (ISH, isolated diastolic hypertension (IDH, and systolic-diastolic hypertension (SDH. Results. Systolic-diastolic hypertension was the most prevalent. Whereas SDH (77.6% versus 73.5% and IDH (4.9% versus 4.7% were more prevalent among females, ISH (10.1% versus 6.2% was higher among males (P=0.048. Female subjects were more obese (P<0.0001 and SDH was prevalent among the obese group. Conclusion. Gender and obesity significantly influenced the distribution of the hypertension subtypes. Characterization of hypertension by subtypes in genetic association studies could lead to identification of previously unknown genetic variants involved in the etiology of hypertension. Large-scale studies among various ethnic groups may be needed to confirm these observations.

Conclusion. High frequency of BP self-measurement was identified together with low compliance of patients to antihypertensive therapy, good knowledge on non-pharmacologic treatment interventions.

  7. Revisiting essential hypertension--a "mechanism-based" approach may argue for a better definition of hypertension.

    Calò, L A

    2009-08-01

    Several major overarching themes have recently emerged in our understanding of the pathophysiology of hypertension which may allow to revisit essential hypertension with an eye towards the possibility of adopting a more rational "mechanistic-based" definition of hypertension and moving away from the unsatisfactory "essential" label for hypertension from unknown cause. As our understanding of the biochemical and physiological mechanisms that control blood pressure rapidly evolves, the "essential" label of hypertension is losing both value as well as utility as it will describe an increasingly small number of hypertensive patients. This paper uses some recently identified pathways central to hypertension and uses this understanding of pathophysiology to argue for a better definition of hypertension.

    A majority of patients with hypertension fail to achieve blood pressure (BP) control despite treatment with commonly prescribed drugs. This randomized, double-blind phase III trial assessed the superiority of sacubitril/valsartan 200 mg (97/103 mg) to continued olmesartan 20 mg in reducing ambulatory systolic BP after 8-week treatment in patients with mild to moderate essential hypertension uncontrolled with olmesartan 20 mg alone. A total of 376 patients were randomized to receive either sacubitril/valsartan (n = 188) or olmesartan (n = 188). Superior reductions in 24-hour mean ambulatory systolic BP were observed in the sacubitril/valsartan group vs the olmesartan group (-4.3 mm Hg vs -1.1 mm Hg, P sacubitril/valsartan vs olmesartan (P sacubitril/valsartan vs olmesartan. The overall incidence of adverse events was comparable between the groups. Compared with continued olmesartan, sacubitril/valsartan was more effective and generally safe in patients with hypertension uncontrolled with olmesartan 20 mg. ©2018 Wiley Periodicals, Inc.

    The aim of this study was to determine and compare cardiovascular risks by assessing arterial stiffness in children with essential hypertension and white coat hypertension. Paediatric patients followed up with essential hypertension and white coat hypertension diagnoses and with no established end organ damage were involved in the study. Arterial stiffness in children included in the study was evaluated and compared by using the oscillometric device (Mobil-O-Graph) method. A total of 62 essential hypertension (34 male, 28 female), 38 white coat hypertension (21 male, 17 female), and 60 healthy controls (33 male, 27 female) were assessed in the present study. Pulse wave velocity of the essential hypertension, white coat hypertension, and control group was, respectively, as follows: 5.3±0.6 (m/s), 5.1±0.4 (m/s), 4.3±0.4 (m/s) (pcoat hypertension were found to be higher compared with the control group. This level was identified as correlated with the duration of hypertension in both patient groups (pcoat hypertension was impaired compared with healthy children. This finding has made us think that white coat hypertension is not an innocent clinical situation. This information should be taken into consideration in the follow-up and treatment approaches of the patients.

    Full Text Available OBJECTIVE: The angiotensin-converting enzyme gene is one of the most studied candidate genes related to atrial fibrillation. Among the polymorphisms of the angiotensin-converting enzyme gene, the 2350 G/A polymorphism (rs4343 is known to have the most significant effects on the plasma angiotensin-converting enzyme concentration. The aim of the present study was to investigate the association of the angiotensin-converting enzyme 2350 G/A polymorphism with atrial fibrillation in Han Chinese patients with essential hypertension. METHODS: A total of 169 hypertensive patients were eligible for this study. Patients with atrial fibrillation (n = 75 were allocated to the atrial fibrillation group, and 94 subjects without atrial fibrillation were allocated to the control group. The PCR-based restriction fragment length polymorphism technique was used to assess the genotype frequencies. RESULTS: The distributions of the angiotensin-converting enzyme 2350 G/A genotypes (GG, GA, and AA, respectively were 40.43%, 41.49%, and 18.08% in the controls and 18.67%, 46.67%, and 34.66% in the atrial fibrillation subjects (p = 0.037. The frequency of the A allele in the atrial fibrillation group was significantly greater than in the control group (58.00% vs. 38.83%, p = 0.0007. Compared with the wild-type GG genotype, the GA and AA genotypes had an increased risk for atrial fibrillation. Additionally, atrial fibrillation patients with the AA genotype had greater left atrial dimensions than the patients with the GG or GA genotypes (p<0.01 and p<0.05, respectively. CONCLUSIONS: The results obtained in this study indicate that the angiotensin-converting enzyme 2350 G/A polymorphism is associated with atrial fibrillation and that the A allele shows an increased risk for atrial fibrillation in Han Chinese patients with essential hypertension.

    To investigate whether red blood cell distribution width (RDW) is associated with the blood pressure (BP) reverse-dipper pattern in patients with hypertension. Cross-sectional study. Single centre. Patients with essential hypertension were included in our study (n=708). The exclusion criteria included age 90 years, incomplete clinical data, night workers, diagnosis of secondary hypertension, under antihypertensive treatment, intolerance for the 24 h ambulatory BP monitoring (ABPM) and BP reading success rate hypertension among different circadian BP pattern groups was analyzed using analysis of variance (ANOVA). Multinomial logistic regression was applied to explore the associations of RDW and other relevant variables with ABPM results. There was significantly increased RDW in reverse dippers (13.52 ± 1.05) than dippers (13.25 ± 0.85) of hypertension (p=0.012). Moreover, multinomial logistic regression analysis showed that RDW (OR 1.325, 95% CI 1.037 to 1.692, p=0.024) and diabetes mellitus (OR 2.286, 95% CI 1.380 to 3.788, p=0.001) were significantly different when comparing the reverse-dipper BP pattern with the dipper pattern. However, there was no difference of RDW between the non-dipper pattern and the reverse-dipper pattern (OR 1.036, 95% CI 0.867 to 1.238, p=0.693). In addition to this, RDW was negatively correlated with the decline rate of nocturnal systolic BP (r=-0.113; p=0.003) and diastolic BP (r=-0.101; p=0.007). Our results suggested that RDW might associate with the abnormal dipper BP patterns of either reverse dipping or non-dipping homogeneously examined with 24 h ABPM.

    A new approach is proposed for the choice of low-frequency magnetic therapy on an individual basis using the results of analysis of heart rhythm variability. The clinical efficiency of low-frequency magnetic therapy incorporated in the combined treatment of 65 patients aged between 25 and 45 years with essential arterial hypertension was estimated. The statistically significant positive effects of the treatment included normalization of blood pressure and characteristics of heart rhythm variability as well as resolution of clinical symptoms of vegetative dysregulation.

  13. Renal Tissue Oxygenation in Essential Hypertension and Chronic Kidney Disease

    Full Text Available Animal studies suggest that renal tissue hypoxia plays an important role in the development of renal damage in hypertension and renal diseases, yet human data were scarce due to the lack of noninvasive methods. Over the last decade, blood oxygenation level-dependent magnetic resonance imaging (BOLD-MRI, detecting deoxyhemoglobin in hypoxic renal tissue, has become a powerful tool to assess kidney oxygenation noninvasively in humans. This paper provides an overview of BOLD-MRI studies performed in patients suffering from essential hypertension or chronic kidney disease (CKD. In line with animal studies, acute changes in cortical and medullary oxygenation have been observed after the administration of medication (furosemide, blockers of the renin-angiotensin system or alterations in sodium intake in these patient groups, underlining the important role of renal sodium handling in kidney oxygenation. In contrast, no BOLD-MRI studies have convincingly demonstrated that renal oxygenation is chronically reduced in essential hypertension or in CKD or chronically altered after long-term medication intake. More studies are required to clarify this discrepancy and to further unravel the role of renal oxygenation in the development and progression of essential hypertension and CKD in humans.

    Objective was to investigate the effects of Tai Chi exercise on nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2S) levels, and blood pressure (BP) in patients with essential hypertension (EH). EH patients were assigned to the Tai Chi exercise group (HTC, n = 24), and hypertension group (HP, n = 16) by patients' willingness. Healthy volunteers matched for age and gender were recruited as control (NP, n = 16). HTC group performed Tai Chi (60 min/d, 6 d/week) for 12 weeks. Measurements (blood glucose, cholesterol, NO, CO, H2S and BP) were obtained at week 0, 6, and 12. SBP, MAP, and low-density lipoprotein cholesterol levels decreased, and high-density lipoprotein cholesterol levels increased by week 12 in the HTC group (all p exercise seems to have beneficial effects on BP and gaseous signaling molecules in EH patients. However, further investigation is required to understand the exact mechanisms underlying these observations, and to confirm these results in a larger cohort.

    Renovascular hypertension occurs in nearly 5 per cent of patients with high blood pressure but nevertheless its diagnosis has important practical implication insofar as a complete cure is possible by resorting to percutaneous transluminal angioplasty or surgery. It is the purpose of this work to develop a radionuclide method for differential diagnosis of the two conditions using 99m Tc-DTPA which contributes to overall functional assessment of the kidneys, and introduces an objective indicator for estimating the extent of renal response to Captopril (C). A total of thirty patients, 25 of them with essential hypertension (EH) and 5 with renovascular hypertension (RVH), are studied. From the obtained data on transit time of kidneys, T max and their perceptual contribution to total renal function in EH patients, it becomes evident that the effect of C on the listed indicators is insignificant (p>0.05). In RVH patients, following drug intake, there is prolongation of the transit time, T max as well as reduced contribution of the kidney affected to total renal function (by over 6 per cent). In conclusion it is stressed that using the noninvasive radionuclide method and quantitative indicators proposed, it is possible to differentiate RVH from EH and renoparenchymal hypertension with a high-degree certainty. 6 refs., 1 tab., 2 figs.

    To compare the efficacy and safety of the angiotensin II antagonist olmesartan medoxomil (O) and the ACE inhibitor ramipril (R) in elderly patients with essential arterial hypertension. After a 2-week placebo wash-out 1102 treated or untreated elderly hypertensive patients aged 65-89 years (office sitting diastolic blood pressure, DBP, 90-109 mmHg and/or office sitting systolic blood pressure, SBP, 140-179 mmHg) were randomized double-blind to 12-week treatment with O 10 mg or R 2.5 mg once-daily. After the first 2 and 6 weeks doses could be doubled in non-normalized [blood pressure (BP) < 140/90 mmHg for nondiabetic and < 130/80 mmHg for diabetic) individuals, up to 40 mg for O and 10 mg for R. Office BPs were assessed at randomization, after 2, 6 and 12 weeks of treatment, whereas 24-h ambulatory BP was recorded at randomization and after 12 weeks. In the intention-to-treat population (542 patients O and 539 R) after 12 weeks of treatment baseline-adjusted office SBP and DBP reductions were greater (P < 0.01) with O [17.8 (95% confidence interval: 16.8/18.9) and 9.2 (8.6/9.8) mmHg] than with R [15.7 (14.7/16.8) and 7.7 (7.1/8.3) mmHg]. BP normalization rate was also greater under O (52.6 vs. 46.0% R, P < 0.05). In the subgroup of patients with valid ambulatory BP recording (318 O and 312 R) the reduction in 24-h average BP was larger (P < 0.05) with O [SBP: 11.0 (12.2/9.9) and DBP: 6.5 (7.2/5.8) mmHg] than with R [9.0 (10.2/7.9) and 5.4 (6.1/4.7) mmHg]. The larger blood pressure reduction obtained with O was particularly evident in the last 6 h from the dosing interval; a better homogeneity of the 24-h BP control with O was confirmed by higher smoothness indices. The proportion of patients with drug-related adverse events was comparable in the two groups (3.6 O vs. 3.6% R), as well as the number of patients discontinuing study drug because of a side effect (14 O vs. 19 R). In elderly patients with essential arterial hypertension O provides an effective, prolonged

    Exercise renography using {sup 99m}Tc-mercaptoacetyltriglycine ({sup 99m}Tc-MAG{sub 3}) permits recognition of a disease specific renal functional disturbance of essential hypertension. This disturbance can be visualized scintigraphically as pronounced bilateral parenchymal/tissue tracer retention. Clearance determinations during light ergometric exercise demonstrated that transitory bilateral tissue tracer retention results from a selective and prominent reduction of glomerular filtration, while effective renal plasma flow (ERPF) remains comparatively stable. Results obtained with exercise renography and with clearance determinations suggest that the physiological relationship between glomerular filtration rate (GFR) and ERPF, i.e. a filtration fraction (FF) of 0.2, is severely disrupted (FF << 0.2) in about 60% of patient with essential hypertension. This functional disturbance must result in the activation of the renin-angiotensin axis. A particularly exciting consequence of this research was the recognition that {sup 99m}Tc-MAG{sub 3}-scintigraphy can visualize a reduced FF. This opens the door to a broad area of research unrelated to essential hypertension. Initial results in renovascular disease and in urinary tract obstruction demonstrated that a reduced FF puts the involved organs at risk. (orig.)

    The incidence of vascular complications in 224 patients with aldosterone-producing adenoma (APA) which was proven on adrenal surgery, was compared to that in 224 sex- and age-matched patients with essential hypertension (EHT). The incidence of cerebral hemorrhage was significantly higher (p < 0.05) in the patients with APA when compared to the EHT group. On the other hand, the incidence of myocardial infarction and/or congestive heart failure in the APA group was lower, although this difference did not reach statistical significance. Diastolic blood pressure in the APA group was significantly higher (p < 0.001) in the EHT group. However, a significant difference in diastolic blood pressure was not detected between the APA groups with and without vascular complications, whereas in the EHT group diastolic blood pressure was significantly higher (p < 0.001) in cases with vascular complications as compared to those without complications. As a possible factor contributing to the higher incidence of cerebral hemorrhage in the APA group, proteinuria was suggested. It was recommended that patients with primary aldosteronism should undergo operation when localization of the APA is established.

Most of them (78%) could be reassessed after 3 month of treatment (beta-blocking drugs or diuretics). The authors also investigated a few numbers (n=10) of patients presenting a hypertensive crisis treated with vasodilatant drugs and diuretics during 1 week of period. The hormonal status of all of them was assessed at the same time. The body composition was determined by multiple-isotope method

    Many studies have focused on Type A and Type D personality types in the context of cardiovascular diseases (CVDs), but nothing is known about how these personality types combine to create new profiles. The present study aimed to develop a typology of Type A and Type D personality in two groups of patients affected by and at risk for coronary disease. The study involved 711 patients: 51.6% with acute coronary syndrome, 48.4% with essential hypertension (mean age = 56.4 years; SD = 9.7 years; 70.7% men). Cluster analysis was applied. External variables, such as socio-demographic, psychological, lifestyle, and clinical parameters, were assessed. Six groups, each with its own unique combined personality profile scores, were identified: Type D, Type A-Negatively Affected, Not Type A-Negatively Affected, Socially Inhibited-Positively Affected, Not Socially Inhibited, and Not Type A-Not Type D. The Type A-Negatively Affected cluster and, to a lesser extent, the Type D cluster, displayed the worst profile: namely higher total cardiovascular risk index, physical inactivity, higher anxiety and depression, and lower self-esteem, optimism, and health status. Identifying combined personality profiles is important in clinical research and practice in cardiovascular diseases. Practical implications are discussed. PMID:27589065

    The authors prospectively observed 373 severe hypertensives with either diastolic blood pressure (BP) ≥ 105 and age ≤ 40, or BP with three drugs ≥ 105 (regardless of age). Excluded were patients who were older than 75 or who had creatinine >400. History, physical examination, and laboratory data were used to identify high-yield criteria for arteriography. All patients underwent angiography as the gold standard; angiography showed 127 unilateral renal artery stenoses, 73 bilateral renal artery stenoses, and 173 (nonstenosed) essential hypertensives. The authors constructed a logistic regression model of height, weight, age, smoking, and hypertension duration, which could be used to identify 90% of stenosed patients with 50% fewer angiographies in the essential hypertensives

    1. In hypertension, the beta-adrenoreceptor-blocker-withdrawal syndrome comprises tachycardia, sweating, tremor and general malaise, symptoms resembling thyrotoxicosis. 2. The effect of abrupt cessation of propranolol on serum concentrations of thyroxine (T4) and triiodothyronine (T3) was therefore investigated in five patients with uncomplicated essential hypertension, treated with propranolol in doses from 160 to 480 mg/day. 3. Four of the five patients developed one or more of the above-mentioned symptoms within 2-6 days after withdrawal of propranolol. 4. A mean relative increase in serum free T3 of 51% (range 22-74%) was found in these four patients on the day of onset of symptoms. 5. The increase in free T3 in the five patients correlated positively with total serum propranolol on the last day the drug was given (r = 0.91, 2P = 0.03). 6. As an increase in T3 was found only in patients suffering the withdrawal syndrome, and was maximal the day the symptoms appeared, despite a variation in time of onset from 2 to 6 days, it is suggested that the beta-adrenoreceptor-blocker-withdrawal syndrome, at least partially, is caused by rebound increased production of T3, induced by the well-known inhibition of the monodeiodination of T4 to T3 during beta-adrenoreceptor blockade. 7. This assumption may explain the clinical symptoms and the reported transient increased beta-adrenoreceptor sensitivity with unchanged serum concentrations of catecholamines.

    Objective: To observe whether there is potential renal function decline in normotensive young offspring of essential hypertensives and to probe into the possible mechanism giving rise to it, providing some clues to the study of the pathogenic and hereditary mechanism of essential hypertension. Methods: Using 99 Tc m -DTPA as the imaging agent, authors performed rest and exercise scintirenography in normotensive young offspring of essential hypertensives [NOH, 31 cases, 14 males, 17 females; mean age: (23.2 ± 4.1) years], normotensive young off-spring of non-hypertensives [NON, 31 cases, 20 males, 11 females; mean age: (23.1±3.6) years], some of the hypertensive parents [21 cases, 5 males, 16 females; mean age: (53.0 ± 5.61) years] and old non-hypertensive subjects [10 cases, 6 males, 4 females; mean age: (53.7 ± 5.2) years]. The results were analyzed with the software of SPSS 10.0 for Windows. Results: Though all of the rest renal function indexes from NOH were within the normal range, there were significant differences between most of those indexes from NOH and those from NON, e. g., t p and MTT from NOH were significantly delayed than those from NON; exercise made these differences more significant, and after exercise, glomerular filtration rate (GFR) and RI were significantly lower, and 20/P was significantly higher. There were 4, 5, 2 cases showing abnormal exercise scintirenography in NOH, hypertensive parents and old non-hypertensive subjects, respectively, but none in NON group. Conclusions: There is potential renal function decline in normotensive young offspring of essential hypertensives. The kidney may play an important role in the pathogenic and hereditary mechanism of essential hypertension

    Radioimmunoassay for the measurement of plasma renin activity (PRA) was performed in 43 normal Koreans and 45 patients with essential hypertension. Plasma samples were drawn in supine position in the morning and after upright posture for 4 hours. Urinary sodium excretion rates were measured in the concurrent 24 hour urine samples, an index of their sodium balance. The results were as follows: 1) There was an inverse correlation between 24 hr sodium excretion and PRA. The normal values of PRA in supine position ranged from 1.0 to 7.0 ng/ml/hr. when 24 hour sodium excretion were between 50 to 150 mEq. PRA in elderly tended to be low. 2) When stimulated by 4 hour upright posture, PRA increased by 2.6 times from the baseline value. 3) Of the 45 patients with essential hypertension, PRA was low in 10 cases (22.2%), normal in 28 cases (62.2%), and high in 7 cases (15.6%). 4) In the normal and high renin groups, who tended to be younger in ages, mean diastolic blood pressure and BUN were higher than in low renin group. Though hypertensive retinopathy and left ventricular hypertrophy in ECG were more prevalent in the former, no significant differences were noted as in the case of serum cholesterol. 5) There were 8 cases of cardiovascular complications (7 with cerebral vascular accident, 1 with myocardial infarction); 3 in low renin group (30%), 2 in normal renin (7.1%) and 3 in higher renin group (42.9%). This figure indicated higher rate of cardiovascular complications in higher renin groups, and lower rate in normal renin group. But the incidence of the complication was not significantly low in low renin group.

  12. Neurological disorders in hypertensive patients

    Full Text Available Hypertension is one of the most common vascular diseases. The brain as target organs in hypertension is damaged more often and earlier. Neurological complications due to hypertension are frequently hyperdiagnosed in Russian neurological practice. Thus, headache, dizziness, impaired recall of recent events, nocturnal sleep disorders, and many other complaints in a hypertensive patient are usually regarded as a manifestation of dyscirculatory encephalopathy. At the same time headaches (tension headache and migraine in hypertensive patients are predominantly primary; headache associated with dramatic marked elevations in blood pressure is encountered in only a small number of patients. The role of cerebrovascular diseases in the development of dizziness in hypertensive patients is also overestimated. The vast majority of cases, patients with this complaint are in fact identified to have benign paroxysmal postural vertigo, Mеniеre’s disease, vestibular neuronitis, or vestibular migraine. Psychogenic disorders or multisensory insufficiency are generally responsible for non-systemic vertigo in hypertensive patients. Chronic cerebral circulatory insufficiency may cause non-systemic vertigo as a subjective equivalent of postural instability.Cognitive impairments (CIs are the most common and earliest manifestation of cerebrovascular lesion in hypertension. In most cases, CIs in hypertension were vascular and associated with cerebrovascular lesion due to lacunar infarcts and leukoaraiosis. However, mixed CIs frequently occur when hypertensive patients are also found to have signs of a degenerative disease, most commonly in Alzheimer’s disease.

    Massage, an ancient Chinese healing art, is widely practiced for symptom relief in hypertensive patients with anxiety, depression, headache, vertigo, chronic pain in neck, shoulder and back. A large number of case series and clinical trials have been published. However, it is still unclear whether massage can be recommended as an effective therapy for essential hypertension (EH). We estimated the current clinical evidence of massage for EH. Articles published before 10 December 2013 were searched using Cochrane Library, PubMed, EMBASE, Chinese Scientific Journal Database (VIP), Chinese Biomedical Literature Database, Wanfang data and Chinese National Knowledge Infrastructure. Randomized controlled trials comparing massage with any type of control intervention were included. Trials testing massage combined with antihypertensive drugs versus antihypertensive drugs were included as well. Meta-analysis was performed on the effects on blood pressure (BP). Twenty-four articles involving 1962 patients with EH were selected. Methodological quality of most trials was evaluated as generally low. Meta-analyses demonstrated that massage combined with antihypertensive drugs may be more effective than antihypertensive drugs alone in lowering both systolic BP (SBP; mean difference (MD): -6.92 (-10.05, -3.80); Phypertensive patients as compared with antihypertensive drugs. Safety of massage is still unclear. There is some encouraging evidence of massage for EH. However, because of poor methodological quality, the evidence remains weak. Rigorously designed trials are needed to validate the use of massage in future.

    1984-01-01

    To assess the frequency and magnitude of phasic renal blood flow changes in essential hypertension, we applied an analytical method based on the estimation of power spectral density to xenon transit through the kidney. Despite similar age and gender distribution of the patients and exclusion of those with accelerated hypertension, mean renal blood flow was significantly lower in 100 patients with essential hypertension (299 +/- 8 ml/100 g/min) than in the 144 normal subjects (335 +/- 6 ml/100 g/min; p less than 0.001). Normalized power, the index of oscillatory behavior, was more than twice normal in patients with essential hypertension (p less than 0.001), but there was no difference in the frequency or cycle length of the oscillation. Two maneuvers that induced renal vasoconstriction, the application of cuffs to the thighs which were then inflated to diastolic blood pressure and an emotional provocation, reduced renal blood flow much more in patients with essential hypertension (p less than 0.01) in association with a striking increase in normalized power (p less than 0.001). The oscillations, which reflected not the phasic blood pressure change but rather the phasic change in renal perfusion, provided additional evidence that renal vasoconstriction plays an active role in the pathogenesis of essential hypertension

    Preeclampsia is a hypertensive complication of pregnancy characterized by novel onset of hypertension after 20 weeks gestation, accompanied by proteinuria. Epidemiological evidence suggests that genetic susceptibility exists for preeclampsia; however, whether preeclampsia is the result of underlying genetic risk for essential hypertension has yet to be investigated. Based on the hypertensive state that is characteristic of preeclampsia, we aimed to determine if established genetic risk scores (GRSs) for hypertension and blood pressure are associated with preeclampsia. Subjects consisted of 162 preeclamptic cases and 108 normotensive pregnant controls, all of Iowa residence. Subjects' DNA was extracted from buccal swab samples and genotyped on the Affymetrix Genome-wide Human SNP Array 6.0 (Affymetrix, Santa Clara, CA). Missing genotypes were imputed using MaCH and Minimac software. GRSs were calculated for hypertension, systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) using established genetic risk loci for each outcome. Regression analyses were performed to determine the association between GRS and risk of preeclampsia. These analyses were replicated in an independent US population of 516 cases and 1,097 controls of European ancestry. GRSs for hypertension, SBP, DBP, and MAP were not significantly associated with risk for preeclampsia (P > 0.189). The results of the replication analysis also yielded nonsignificant associations. GRSs for hypertension and blood pressure are not associated with preeclampsia, suggesting that an underlying predisposition to essential hypertension is not on the causal pathway of preeclampsia. © American Journal of Hypertension, Ltd 2015.

    A radioimmunoassay was developed to measure endothelin-like immunoreactivity in human plasma using antibody raised against endothelin-1 which also cross-reacts with big endothelin-1 and endothelin-2 but not endothelin-3. The sensitivity was 1 fmol/tube with inter- and intra-assay coefficients of variation of 13% and 9%, respectively. Cross-reactivity with endothelin-3 and non-endothelin peptides was less than 1%. Endothelin-like immunoreactivity was present in plasma of hypertensive patients (n = 25) at 5.7±0.5 pmol/1 (mean±SEM), not significantly different from that of age-matched control subjects (5.1±0.5 pmol/1). At these levels, endothelin-1 is unlikely to function as a circulating hormone. In the normotensive group, the concentration of endothelin-like immunoreactivity in plasma was positively correlated with mean arterial blood pressure, but in hypertensive patients it showed significant negative correlation.

    This study is to investigate the effects of slow breathing on heart rate variability (HRV) and arterial baroreflex sensitivity in essential hypertension.We studied 60 patients with essential hypertension and 60 healthy controls. All subjects underwent controlled breathing at 8 and 16 breaths per minute. Electrocardiogram, respiratory, and blood pressure signals were recorded simultaneously. We studied effects of slow breathing on heart rate, blood pressure and respiratory peak, high-frequency (HF) power, low-frequency (LF) power, and LF/HF ratio of HRV with traditional and corrected spectral analysis. Besides, we tested whether slow breathing was capable of modifying baroreflex sensitivity in hypertensive subjects.Slow breathing, compared with 16 breaths per minute, decreased the heart rate and blood pressure (all P hypertensive subjects. Slow breathing increased baroreflex sensitivity in hypertensive subjects (from 59.48 ± 6.39 to 78.93 ± 5.04 ms/mm Hg, P hypertension. Besides, slow breathing increased baroreflex sensitivity in hypertensive subjects. These demonstrate slow breathing is indeed capable of shifting sympatho-vagal balance toward vagal activities and increasing baroreflex sensitivity, suggesting a safe, therapeutic approach for essential hypertension.

    Full Text Available Objectives- To study the prescription pattern of antihypertensive drugs and analyze the medication adherence to antihypertensive drugs at rural tertiary care teaching hospital.Materials and Methods- Prospective, observational, 12 weeks, questionnaire based study, conducted in rural tertiary care teaching hospital of central India. 214 antihypertensive prescriptions were analyzed by Morisky medication adherence scale. Statistical analysis was done by MS Excel and Graph pad prism 6.0.Results- 28.03% patients were not aware about the medicines taken, 29.90% patients were unacquainted about dose and route of administration whereas 32.71% patients were unfamiliar about frequency of administration of medicines. 53.27% patients were unaware about precautions to be taken while consuming medicines.  58.68% & 12.67% patients consumed amlodipine & atenolol respectively. In 16.43% patients, atenolol + amlodipine combination therapy was prescribed.  Amongst 214 patients 12, 58 & 144 showed high, medium & low adherence respectively.  No significant difference was found on gender basis at any level of adherence.Conclusion- In this study, physicians given preference to amlodipine than other antihypertensive drugs. However, thiazide is a first line drug in stage 1 hypertension, recommended by JNC VII guideline. This indicates that there is need of creating awareness about current management of hypertension to clinicians by organizing various workshops. We observed only 5.60% patients showed high adherence to antihypertensive therapy. Therefore educational strategies must be carried out for physicians focusing on causes for nonadherence to antihypertensive medications. Also raising patient trust in their physicians may improve patient motivation to prescribed medication.

    To assess whether an association between sodium-sensitive hypertension and metabolic syndrome exists; and whether, in patients with metabolic syndrome, the nocturnal fall of blood pressure decreases and salt restriction affects the circadian blood pressure rhythm. Japanese patients with essential hypertension, who were treated without any antihypertensive agent, were maintained on a high-sodium diet and a low-sodium diet for 1 week each. On the last day of each diet, the 24-h blood pressures were measured. A diagnosis of metabolic syndrome was made according to the International Diabetes Foundation definition Among the 56 patients with essential hypertension, 15 patients were complicated with metabolic syndrome while 41 patients were not. The nocturnal blood pressure fall was significant in patients without metabolic syndrome, while it was not so in patients with metabolic syndrome. Only in patients with metabolic syndrome was the nocturnal blood pressure fall enhanced by sodium restriction. The prevalence of sodium-sensitive hypertension in patients with metabolic syndrome was significantly higher than in those without metabolic syndrome (70.6 versus 36.0%, respectively; P = 0.017). A multiple logistic regression analysis revealed central obesity to be an independent risk factor for sodium-sensitive hypertension (odds ratio, 1.41; 95% confidence interval, 1.04-1.91). In patients with essential hypertension, an inter-relationship exists among metabolic syndrome, enhanced sodium sensitivity of the blood pressure and non-dipping. The elevated risk of cardiovascular diseases in patients with metabolic syndrome may be related to sodium-sensitive hypertension and non-dipping.

    There is a known association between chemotherapy and radiotherapy for treatment of cancer patients and development or worsening of hypertension. The aim of this article is to review this association. A literature search was conducted for articles reporting this association on the databases PubMed, SciELO and LILACS between 1993 and 2013. There was a high coprevalence of hypertension and cancer, since both diseases share the same risk factors, such as sedentary lifestyle, obesity, smoking, unhealthy diet and alcohol abuse. The use of chemotherapy and adjuvant drugs effective in the treatment of cancer increased the survival rate of these patients and, consequently, increased the incidence of hypertension. We described the association between the use of angiogenesis inhibitors (bevacizumab, sorafenib and sunitinib), corticosteroids, erythropoietin and non-steroidal anti-inflammatory drugs with the development of hypertension. We also described the relationship between hypertension and carotid baroreceptor injury secondary to cervical radiotherapy. Morbidity and mortality increased in patients with cancer and hypertension without proper antihypertensive treatment. We concluded that there is need for early diagnosis, effective monitoring and treatment strategies for hypertension in cancer patients in order to reduce cardiovascular morbidity and mortality.

    BACKGROUND: In Nigeria, systemic hypertension is the commonest noncommunicable disease, and public awareness about hypertension and its determinants is poor. This study aims to assess the knowledge and level of awareness of the disease among hypertensive patients attending the medical outpatient clinic of Olabisi Onabanjo University Teaching Hospital (OOUTH). METHODOLOGY: Hypertensive patients who attended the medical outpatient clinic during the one-year study period and gave their consent were recruited into the study. Response to a questionnaire on various aspects of hypertension was analyzed using the STATA for Windows software. RESULTS: There were 254 hypertensive patients, of which 111 were males and 143 were females, giving a male: female ratio of 1:1.3. The mean age (SD) of the patients was 51 years +/- 12.2; 52.4% of the participants were aware that hypertension was the commonest noncommunicable disease in Nigeria. About one in 10 patients (11.4%) was aware that "nil symptom" is the commonest symptom of hypertension, while 37% were not aware that hypertension could cause renal failure. Only about one-third (35.4%) of the patients knew that hypertension should ideally be treated for life, while 58.3% believed that antihypertensive drugs should be used only when there are symptoms. The remaining 6.3% believed that the treatment of hypertension should be for periods ranging from two weeks to five years but not for life. CONCLUSION: This study has demonstrated inadequate knowledge of hypertension in patients with hypertension in our study population. Conscious efforts should be made and time set aside to health educate hypertensive patients. Organization of "hypertensive club or society" could be encouraged. These will reduce dissemination of false or inaccurate information by hypertensive patients to the public and its attendant dangers. PMID:15160976

    In a previous work we studied, non-invasively, autonomic nervous system control of circulation in healthy subjects, observing the hemodynamic reaction to active standing. We now propose to extend this analysis to essential hypertension (EH), investigating possible autonomic dysfunction. The cardiovascular response to postural change from the supine position to active standing of 48 EH patients, of both sexes, with and without medication, was compared with that obtained for healthy subjects. We evaluated arterial systolic (SBP) and diastolic (DBP) blood pressure, stroke volume (SV), inotropic index (INOI), total vascular resistance (TVR), cardiac work (W), stroke work (SW), arterial compliance (AC) and heart rate (HR), using the entirely non-invasive BoMed NCCOM3 thoracic electrical bioimpedance monitor and sphygmomanometry. We found two patient groups characterized by different linear relationships between values of cardiovascular variables in active standing and in supine positions. Except for HR, in both groups these regression lines differed from normal. Compared to the supine position, in active standing, one group (EH-I) presented increased TVR, diminished SV, INOI, W, SW, and AC, and normal HR; the other group (EH-II) presented diminished TVR and HR and increased SV, INOI, W, SW and AC. The two patient groups could be separated on the basis of their age, but not on the basis of their systolic, diastolic and mean arterial blood pressures, gender or medication. The younger patient group (EH-I) included 28 subjects aged 24 to 69 years (50+/-10), of whom 11 were unmedicated, and the older patient group (EH-II) included 20 subjects aged 35 to 75 years (62+/-11), of whom 7 were unmedicated. Our results show a depressed response in postural change for older patients, which in the autonomic control of circulation expresses carotid baroreflex impairment, and conversely an enhanced response for younger patients, which can be caused by a maladjustment of the influence

    Full Text Available INTRODUCTION: Thrombocytopenia poses a significant problem in the elderly. Not only are there varied causes, but it is also associated with significant morbidity and mortality. We carried out a study to learn the causes of isolated thrombocytopenia in elderly patients and to correlate the severity of thrombocytopenia and bleeding manifestations with various etiologic factors and comorbidities. METHODS: A total of 108 patients above 50 years of age presenting with isolated thrombocytopenia (platelet counts of <100x109/L with normal hemoglobin and total leukocyte counts were enrolled in the study. Detailed history and clinical examinations were carried out for each patient. Complete blood counts were analyzed by automated cell counter. Peripheral smears were examined in all cases. HbsAg, anti-HCV, and anti-HIV testing by enzyme-linked immunosorbent assay was done in all patients. Wherever clinically indicated, bone marrow aspiration biopsy and cytogenetic studies were done. RESULTS: Out of 108 patients, 102 (94.4% presented with bleeding tendencies. Twenty-nine (26.8% presented with serious (World Health Organization grade 3/4 bleedings. Major findings were immune thrombocytopenic purpura in 79 (73.1%, myelodysplastic syndrome in 7 (6.5%, drug-induced thrombocytopenia in 7 (6.5%, and connective tissue disorder in 4 (3.7% cases. Ten patients presented with intracranial bleedings. Upon logistic regression analysis, comorbidities in the form of essential hypertension and diabetes mellitus were significantly associated with occurrence of intracranial bleeding. There was no correlation of serious bleedings with platelet counts. DISCUSSION AND CONCLUSION: Isolated thrombocytopenia in the elderly is associated with significant morbidity. Diligent clinical and laboratory evaluation is required to elucidate the cause of thrombocytopenia in the elderly. Comorbidities in this population are associated with serious bleedings and not low platelet counts as is

    2018-05-01

    The goal of this study was to investigate genes associated with essential hypertension from a system perspective, making use of bioinformatic tools to gain insights that are not evident when focusing at a detail-based resolution. Using various databases (pathways, Genome Wide Association Studies, knockouts etc.), we compiled a set of about 200 genes that play a major role in hypertension and identified the interactions between them. This enabled us to create a protein-protein interaction network graph, from which we identified key elements, based on graph centrality analysis. Enriched gene regulatory elements (transcription factors and microRNAs) were extracted by motif finding techniques and knowledge-based tools. We found that the network is composed of modules associated with functions such as water retention, endothelial vasoconstriction, sympathetic activity and others. We identified the transcription factor SP1 and the two microRNAs miR27 (a and b) and miR548c-3p that seem to play a major role in regulating the network as they exert their control over several modules and are not restricted to specific functions. We also noticed that genes involved in metabolic diseases (e.g. insulin) are central to the network. We view the blood-pressure regulation mechanism as a system-of-systems, composed of several contributing subsystems and pathways rather than a single module. The system is regulated by distributed elements. Understanding this mode of action can lead to a more precise treatment and drug target discovery. Our analysis suggests that insulin plays a primary role in hypertension, highlighting the tight link between essential hypertension and diseases associated with the metabolic syndrome.

    Renovascular hypertension superimposed on essential hypertension, a condition encountered in the elderly, was studied. An experimental animal model consisting of a two-kidney one-clip Goldblatt preparation in the spontaneous hypertensive (SHR) rat, that would simulate this condition, was designed. A 0.25 mm silver clip was placed on the left renal artery of SHR male rats. The same procedure performed on WKY rats served as control. All experiments were performed on low, normal, and rich sodium diet. Systolic blood pressure (BP) was measured by tail-cuff method. Plasma renin concentration (PRC) was determined before and after clipping of the renal artery. Results were as follows: Mean systolic BP increased significantly in clipped rats fed with normal and rich sodium diets. SHR showed an increase from 144 +/- 3 (mean + s.e.m.) to 168 +/- 3 mmHg, and WKY rats showed an increase from 120 +/- 2 to 139 +/- 5 mmHg. There was a two- to threefold rise in PRC. A low-salt diet given prior to clipping prevented the appearance of renovascular hypertension despite a significant rise in PRC. We concluded that renal artery narrowing plays a significant role in the rise of BP in the basically essential type of hypertension.

    Full Text Available Essential hypertension is a major health problem causing excess cardiovascular morbidity and mortality. Management of essential hypertension consists of pharmacological and nonpharmacological interventions. In order to prevent and/or treat hypertension, parameters like nutrition, body weight, and physical exercise should be evaluated and taken under consideration for improvement. A large body of evidence clearly support that the role of salt, alcohol, fruits, and vegetables is important for high blood pressure. Furthermore, maintaining a normal body weight should be succeeded along with physical activity few times per week if not daily. Nonpharmacological intervention is rather a dynamic procedure that takes a multilevel approach with repeated training of the hypertensives by a team of expert physicians, rather than a single based guidance. Additionally, it should be based on a profile customization and personalized approach. Intensive interventions aiming at lifestyle changes through educational meetings are considered more effective in lowering high blood pressure. This consists of a lifestyle modification with a permanent basis for patient’s daily schedule and eventually should become a philosophy for a better quality of life through improvement of nutritional and exercise behavior. Further studies are needed so intervention guideline models can be even more effective for patients with essential hypertension.

    Insulin resistance is recognized as the pathophysiological hallmark of non-alcoholic fatty liver disease (NAFLD). A relation between insulin sensitivity and left ventricular morphology and function has been reported in essential hypertension, where a high prevalence of NAFLD has been recently found. We investigated the inter-relationship between left ventricular morphology/function, metabolic parameters and NAFLD in 86 never-treated essential hypertensive patients subdivided in two subgroups according to the presence (n = 48) or absence (n = 38) of NAFLD at ultrasonography. The two groups were similar as to sex, age and blood pressure levels. No patient had diabetes mellitus, obesity, hyperlipidemia, or other risk factors for liver disease. Body mass index, waist circumference, triglycerides, glucose, insulin, homeostasis model of assessment index for insulin resistance (HOMA-IR), aspartate aminotransferase and alanine aminotransferase were higher and adiponectin levels were lower in patients with NAFLD than in patients without NAFLD, and were associated with NAFLD at univariate analysis. Patients with NAFLD had similar prevalence of left ventricular hypertrophy compared to patients without NAFLD, but a higher prevalence of diastolic dysfunction (62.5 vs 21.1%, P 220 ms. Diastolic dysfunction (P = 0.040) and HOMA-IR (P = 0.012) remained independently associated with NAFLD at backward multivariate analysis. Non-alcoholic fatty liver disease was associated with insulin resistance and abnormalities of left ventricular diastolic function in a cohort of patients with essential hypertension, suggesting a concomitant increase of metabolic and cardiac risk in this condition.

    to evaluate morphological changes (intima-media thickness, IMT) of the carotid arteries in patients being treated for essential hypertension (EH), and to discover whether this abnormality can be detected in normotensive offspring of subjects with EH (familial trait, FT); and to investigate the interrelationship between IMT and accompanying risk factors. cross-sectional study. angiology department, university teaching hospital. the study encompassed 172 subjects, of whom 46 were treated hypertonics aged 40-55 (49) years, and 44 age matched, normotensive volunteers as controls. We also investigated 41 normotensives with FT for essential hypertension aged 20-30 (25) years and 41 age- and sex-matched controls without FT. the hypertensive subjects were being treated either with long-acting calcium-channel antagonists or ACE-inhibitors. using high resolution ultrasound, IMT of the carotid bifurcation and of the common carotid artery was measured. In the hypertensives, the mean IMT was greater than that in the controls (0.92 (0.10) mm vs 0.72 (0.07) mm; p<0.00005). The IMT was independently related to accompanying risk factors: a positive family history of hypertension, age of the patient, duration of EH and the level of systolic/diastolic blood pressure (BP), body mass index and total/LDL-cholesterol. In subjects with FT, IMT was also greater compared to the control group (0.60 (0.05) mm vs 0.55 (0.04) mm; p<0.00005). IMT was not related to BP values. In treated essential patients with the EH, the IMT was increased. Individuals with FT also had greater IMT in the absence of elevated BP. The IMT in hypertensives was related to accompanying risk factors, which could be pathogenetic determinants of EH and/or its complications.

    Full Text Available Introduction: Hypertension is a chronic asymptomatic disease, often goes unnoticed for decades before it presents to the medical fraternity with devastating consequences. Low patient adherence is amenable for modification for better control of hypertension, if factors contributing to it are understood. Study was undertaken with the aims of assessing the factors responsible and their relative contributions toward nonadherence among hypertensives. Materials and Methods: We conducted a prospective observational study from August 2013 to August 2014. We included those, who attended the medicine outpatient department with a diagnosis of essential hypertension of more than 1 year duration. Results: A total of 516 patients were enrolled in the study, of which 132 (25.58% were nonadherent. Marital status (P = 0.017, socioeconomic status (P = 0.000, level of education (P = 0.034, such as, illiteracy was associated with highest level of nonadherence compared with those with pre-matric and undergraduate education, whereas those with post graduate level of education showed absolute adherence to drugs and domiciliary status (P = 0.045 had statistically significant association with nonadherence. Other factors like younger age and male sex were associated with a higher degree of nonadherence, however statistical significance could not be obtained.

    The renal and intrarenal haemodynamic pattern in 17 patients with essential hypertension of different severity and duration was studied by means of the 133-Xenon washout technique and the selective renal angiography. The mean and the cortical renal blood flows were on average significantly decreased as compared to the controls. A good agreement was found between the reduction in renal perfusion and the degree of vascular abnormalities as shown by angiography; on the contrary no correlation was found between the impairment in renal blood flow and the degree and/or duration of hypertension

    Ketanserin, an antagonist highly selective for 5-hydroxytryptamine (serotonin) type 2 (S2) receptors, was given as monotherapy in a dose of 40 mg b.i.d. to 24 subjects with mild to moderate essential hypertension. Its effects were evaluated in a placebo-controlled double-blind crossover study. The effect on blood pressure in 18 subjects was monitored by 24-hour ambulatory intra-arterial measurements. Systolic and diastolic intra-arterial pressures were significantly lowered by ketanserin both during the day and at night, whereas heart rate was unchanged. Cuff pressure readings (triplicate measurements) with the London School of Hygiene sphygmomanometer and an automatic device (12 measurements in 1 hour) in the outpatient clinic also showed a significant effect on both supine and standing pressures. No postural hypotension was noted. Ketanserin had no effect on endogenous creatinine clearance, serum cholesterol levels, and the plasma levels of norepinephrine, renin, and aldosterone. The only side effect that was significantly more common with ketanserin than with placebo treatment was an increase in body weight. Ketanserin may have a place in the treatment of mild to moderate essential hypertension.

    As a global measure of ventricular systolic and diastolic function, the myocardial performance index (MPI) can be an early indicator of hypertensive cardiomyopathy in children with essential hypertension (EH). Children with untreated newly diagnosed EH and white coat hypertension (WCH) by a 24-hour ambulatory blood pressure monitoring (ABPM), both groups without any identifiable etiology for the hypertension, were enrolled for the study. Echocardiograms and vascular ultrasounds for carotid artery intimal medial thickness were performed on all children prior to therapy. Diastolic function (peak E and A velocities, E/A ratio, isovolumic relaxation time, and deceleration times) and MPI were evaluated by simultaneous transmitral and transaortic spectral Doppler flow velocities. Systolic function was evaluated by shortening fraction and ejection fraction. A cohort of 66 children (24 with EH, 42 with WCH, males 61%, median age of 13 years, range 10-17 years) were enrolled in the study. The demographic, anthropometric, laboratory tests, vascular ultrasound, and conventional echocardiographic parameters were similar between the 2 groups. There was a very small difference in MPI between the EH and WCH children (0.28 SD: 0.07 vs. 0.31 SD: 0.08, P = 0.045). However, in EH children, MPI increased by 0.14 units for every 10 unit increase in mean ABPM systolic BP (95% confidence interval: 0.03-0.25). We found the increasing MPI was associated with increasing 24-hour mean systolic BP in children with EH. Therefore, MPI may have utility as a single, quick, noninvasive method of detection and tracking of subclinical hypertensive heart disease. © American Journal of Hypertension, Ltd 2015.

    Thiazide diuretics are associated with increased risk of diabetes mellitus. This risk may arise from K(+)-depletion. We hypothesised that a K(+)-sparing diuretic will improve glucose tolerance, and that combination of low-dose thiazide with K(+)-sparing diuretic will improve both blood pressure reduction and glucose tolerance, compared to a high-dose thiazide. This is a parallel-group, randomised, double-blind, multicentre trial, comparing hydrochlorothiazide 25-50 mg, amiloride 10-20 mg and combination of both diuretics at half these doses. A single-blind placebo run-in of 1 month is followed by 24 weeks of blinded active treatment. There is forced dose-doubling after 3 months. The Primary end point is the blood glucose 2 h after oral ingestion of a 75 g glucose drink (OGTT), following overnight fasting. The primary outcome is the difference between 2 h glucose at weeks 0, 12 and 24. Secondary outcomes include the changes in home systolic blood pressure (BP) and glycated haemoglobin and prediction of response by baseline plasma renin. Eligibility criteria are: age 18-79, systolic BP on permitted background treatment ≥ 140 mm Hg and home BP ≥ 130 mm Hg and one component of the metabolic syndrome additional to hypertension. Principal exclusions are diabetes, estimated-glomerular filtration rate 200 mm Hg or DBP >120 mm Hg (box 2). The sample size calculation indicates that 486 patients will give 80% power at α=0.01 to detect a difference in means of 1 mmol/L (SD=2.2) between 2 h glucose on hydrochlorothiazide and comparators. PATHWAY-3 was approved by Cambridge South Ethics Committee, number 09/H035/19. The trial results will be published in a peer-reviewed scientific journal.

    Among people with essential hypertension, ambulatory BP measurement is superior to BP obtained in the clinic in predicting cardiovascular outcomes. In part, this is because it can detect white-coat hypertension and masked hypertension. Whether the same is true for hemodialysis patients is not known. Using a threshold of 140/80 mmHg for median midweek dialysis-unit BP and 135/85 mmHg for 44-hour ambulatory BP, we defined four categories of BP: sustained normotension (SN), white-coat hypertension (WCH), masked hypertension (MHTN), and sustained hypertension (SHTN). Among 355 long-term hemodialysis patients, the prevalence of SN was 35%, WCH 15%, MHTN 15%, and SHTN 35%. Over a mean follow-up of 29.6 (SD 21.7) months, 102 patients died (29%), yielding a crude mortality rate of 121/1000 patient-years. Unadjusted and multivariate-adjusted analyses showed increasing all-cause mortality with increasing severity of hypertension (unadjusted hazard ratios from SN, WCH, MHTN, SHTN: 1, 1.12, 1.70, 1.80, respectively [P for trend hypertension population, MHTN and WCH have prognostic significance. The prognostic value of BP obtained in the dialysis unit can be refined with ambulatory BP monitoring.

    The prevalence and effect of single-parent families in childhood-onset essential hypertension (EH) is unknown. Children with EH and age-, sex-, and ethnicity-matched controls were enrolled. Family structure data were obtained by in-person interview. A total of 148 families (76 hypertension probands, 72 control probands; median 14 years) were prospective-ly enrolled in the study. Single-parent status was seen in 42% of the families--with and without EH (38% vs 46%, P=.41; odds ratio, 0.7; 95% confidence interval, 0.4-1.4). After multivariable analysis, a statistically significant sociofamilial contributor to the development of childhood-onset EH was not identified. A significant number of single-parent families (42%), the majority with single mothers, were found in our pedigree study. Sociofamilial factors are known to contribute to the expression of adult-onset EH, but findings in our study suggest that they appear to contribute less in the expression of childhood-onset EH. ©2015 Wiley Periodicals, Inc.

    Full Text Available Objective. This study aimed to investigate the association between three polymorphisms of renin-angiotensin system and the essential hypertension in the population of Burkina Faso. Methodology. This was a case-control study including 202 cases and 204 matched controls subjects. The polymorphisms were identified by a classical and a real-time PCR. Results. The AGT 235M/T and AT1R 1166A/C polymorphisms were not associated with the hypertension while the genotype frequencies of the ACE I/D polymorphism between patients and controls (DD: 66.83% and 35.78%, ID: 28.22% and 50.98%, II: 4.95% and 13.24%, resp. were significantly different (p < 10−4. The genotype DD of ACE gene (OR = 3.40, p < 0.0001, the increasing age (OR = 3.83, p < 0.0001, obesity (OR = 4.84, p < 0.0001, dyslipidemia (OR = 3.43, p = 0.021, and alcohol intake (OR = 2.76, p < 0.0001 were identified as the independent risk factors for hypertension by multinomial logistic regression. Conclusion. The DD genotype of the ACE gene is involved in susceptibility to hypertension. Further investigations are needed to better monitor and provide individualized care for hypertensive patients.

    Globally essential hypertension and cardiovascular diseases are associated with high morbidity and mortality due to unhealthy life styles and lack of preventative measures. In some ethnicities these factors are insignificant due to genetic makeup favoring protection against these diseases. To study the prevalence of risk factors for essential hypertension in the Pakistani population of a desert area of Thar. A random cross sectional study was done from 2002 to 2008 on 276 subjects (126 males, 150 females) in Islamkot-Thar, the desert area of Sindh. Data for anthropometric, demographic, socioeconomic, dietary pattern, basal metabolic index, body fat content, antihypertensive use and psychosocial factors were recorded. Three consecutive readings for blood pressure were taken in 15 minutes. Any systolic blood pressure of over 140mm Hg and diastolic of over 90mm Hg in all 3 readings was taken as hypertension. Study population was divided in hypertensives (patients) and non hypertensives (controls). Data were analyzed in two steps clinically, descriptively and inferentially using SPSS version 14, first for entire population and second by breaking this population into two sub ethnicities having no consanguinity in them. Hypertension was seen in (10.9%) cases while 88.4 % were normotensive. Hypertensive group showed increased association of risk factors e.g. male gender, old age, marriage, moderately high monthly income, lack of exercise, low leisure time activity, prolonged tobacco exposure, parental history, high basal metabolic index profile, intermediate body fat content and stressful job. However, this group showed lack of association of factors like alcohol, extra salt, scarce education and stress. Decrease association with saturated fat was seen as compared to oil (20.7% versus 79.3%). Subethnicity analysis of the two communities, both having no consanguinity showed one group to be suffering from essential hypertension (17%) and its comorbids like diabetes mellitus

    Plasma from black male patients with essential hypertension was bioassayed for vascular Na+-K+ pump inhibitory activity. Halves of the same rat tail artery were incubated for two hours in boiled plasma supernates from a hypertensive patient and a paired age-, sex-, and race-matched normotensive subject and then ouabain-sensitive 86 Rb uptake was measured. Ouabain-sensitive 86 Rb uptake by their leukocytes was also measured. Eighteen pairs of subjects were studied. The uptakes were not significantly different in the hypertensive patients and control subjects. However, when we selected from the eighteen hypertensive patients, nine with low plasma renin activity on the day of the study, uptakes were reduced in the hypertensive patients relative to the paired control subjects. We also assayed plasma supernates from normotensive black and white male subjects before and after acute volume expansion (2.5 L saline IV + 1.5 L distilled water orally over a three-hour period) and from paired normotensive subjects before and after sham volume expansion and obtained a positive bioassay in the expanded subjects both on intraindividual and interindividual comparisons. These studies demonstrate increased vascular Na+-K+ pump inhibitory activity in the plasma of black male patients with low renin essential hypertension and in the plasma of normotensive subjects after acute volume expansion. The findings suggest that the inhibitory activity in the hypertensive subjects' plasma is related to volume expansion, relative or absolute

    The association between apo E isoforms and insulin output during the oral glucose test (OGTT) in 60 non-diabetic, non-obese patients with essential hypertension and in control subjects (non-obese, non-diabetic normotensive subjects) was estimated. According to low or high insulin output during OGTT, the subjects were divided into the following groups: normotensive subjects with low (NLI) and high (NHI) and hypertensive subjects with low (HLI) and high (HHI) insulin output. The apo E 4/2 phenotype was detected in 32% of hypertensive subjects but not in control subjects. The frequency of apo E 3/2 phenotype in hypertensive subjects was 5% and in normotensive subjects 15%. An increased frequency of phenotype apo E 4/3 was noticed both in HHI (46%) and in NHI (50%) compared with HLI (22%) and NLI (17%) groups. The results suggest that the determination of phenotypes apo E and insulin output may contribute to an early detection of individuals at high risk of hypertension development.

    To assess the potential effect of hypertension on the results of thallium-201 stress imaging in patients with chest pain, 272 thallium-201 stress tests performed in 133 hypertensive patients and 139 normotensive patients over a 1-year period were reviewed. Normotensive and hypertensive patients were similar in age, gender distribution, prevalence of cardiac risk factors (tobacco smoking, hyperlipidemia, and diabetes mellitus), medications, and clinical symptoms of coronary disease. Electrocardiographic criteria for left ventricular hypertrophy were present in 16 hypertensive patients. Stepwise probability analysis was used to determine the likelihood of coronary artery disease for each patient. In patients with mid to high likelihood of coronary disease (greater than 25% probability), abnormal thallium-201 stress images were present in 54 of 60 (90%) hypertensive patients compared with 51 of 64 (80%) normotensive patients. However, in 73 patients with a low likelihood of coronary disease (less than or equal to 25% probability), abnormal thallium-201 stress images were present in 21 patients (29%) of the hypertensive group compared with only 5 of 75 (7%) of the normotensive patients (p less than 0.001). These findings suggest that in patients with a mid to high likelihood of coronary artery disease, coexistent hypertension does not affect the results of thallium-201 exercise stress testing. However, in patients with a low likelihood of coronary artery disease, abnormal thallium-201 stress images are obtained more frequently in hypertensive patients than in normotensive patients

    An association between anxiety and depression and increased blood pressure (BP) and cardiovascular disease risk has not been firmly established. We examined the hypothesis that anxiety and depression lead to increased plasma catecholamines and to production of reactive oxygen species (ROS) by mononuclear cells (MNC) in hypertensive individuals. We also studied the role of BP in this effect. In Protocol 1, a cross-sectional study was performed in 146 hypertensive patients to evaluate whether anxiety and depression affect BP and ROS formation by MNC through increasing plasma catecholamines. In Protocol 2, a 6-month randomized controlled trial using a subtherapeutic dose of the alpha(1)-adrenergic receptor antagonist doxazosin (1 mg/day) versus placebo in 86 patients with essential hypertension was performed to determine whether the increase in ROS formation by MNC was independent of BP. In Protocol 1, a significant relationship was observed between the following: trait anxiety and plasma norepinephrine (r = 0.32, P anxiety may increase plasma norepinephrine and increase ROS formation by MNC independent of BP in hypertensive patients.

    Objective: To investigate the possible relationship existing between serum sex hormones levels and development of essential hypertension. Methods: Serum sex hormones (LH, FSH, E 2 , P, T) levels were determined with RIA in 87 males and 81 post-menopausal women with essential hypertension as well as in 44 normotensive males and 40 normotensive post-menopausal women serving as controls. Results: The serum E 2 , progesterone and testosterone levels in the hypertensives were significantly higher than those in the respective controls (P 0.05). Sex hormones levels were not much different among hypertensives of various stages (I , II, III). The serum E 2 levels in male hypertensives and progesterone levels in female hypertensives were not correlated with the respective FSH and LH levels. Conclusion: The authors suggested that the changes of serum sex hormones levels might be a risk factor rather than a consequence of the development of essential hypertension. (authors)

    Low serum 25-hydroxyvitamin D [25(OH)D] levels may have an important role in predisposing to hypertension and myocardial disease. We investigated the relationship between 25(OH)D and left ventricular (LV) structure and function, assessed by echocardiography, in a series of patients with essential hypertension (EH). Sixty-two newly diagnosed never-treated patients (32 male/30 female), aged 18-65 years, with grade 1-2 hypertension, no diabetes, no obesity, no hyperlipidemia, and no cardiopulmonary, renal, or hepatic disease, were studied. Twenty-four healthy normotensive sex-, age-, BMI-matched subjects served as controls. Hypertensive patients with 25(OH)D deficiency, defined as serum 25(OH)D levels <50 nmol/L, had higher prevalence of LV hypertrophy (LVH) than their 25(OH)D-sufficient counterparts (57.1 vs 17.6%, P = 0.02); no differences between the two groups were found in blood pressure levels as well as in other biochemical and hormone parameters. There was an inverse correlation between LV mass index and 25(OH)D levels (r = -0.366, P < 0.003) and a direct correlation between LV mass index and BMI (r = 0.333, P < 0.006) in the entire hypertensive population. The two variables remained independently associated with LVH at multivariable logistic regression analysis (OR 1.05, P < 0.005 and OR 1.25, P = 0.03, respectively). Prevalence of 25(OH)D deficiency was similar in EH patients and controls (45.1 vs 41.6%, P = 0.89), whereas no correlation between echocardiographic parameters and hormone levels was found. In the absence of major cardiovascular risk factors, 25(OH)D deficiency is a frequent finding in EH patients and is independently associated with LVH. Copyright © 2011 Elsevier B.V.

    Full Text Available Essential hypertension in children is a very important biological aspect in child pathology, caused by the synergic action of multiple risk factors, with an increasing prevalence. Since there is not much knowledge about juvenile essential hypertension in childhood, in this paper we will clarify the existing data about this pathology and its management, mainly by referring to the correlations during different stages. We found significant correlations between hypertension and the individual values of birth weight and gestational age, which suggest that there is an important relationship between birth weight and gestational age, as important biological markers vs. the different stages of essential hypertension.

    Whether changes over time of urinary albumin excretion have prognostic value is a matter of discussion. The objective was to assess the prognostic value of changes in urinary albumin excretion over time in cardiovascular risk during antihypertensive treatment. Follow-up study of 2835 hypertensives in the absence of previous cardiovascular disease (mean age 55 years, 47% men, BP 138/80 mm Hg, 19.1% diabetics, and calibrated systemic coronary risk estimation 5 or >10.6%). Usual-care of antihypertensive treatment was implemented to maintain blood pressure<140/90 mm Hg. Urinary albumin excretion was assessed yearly, and the values were expressed as the creatinine ratio. Incidence of cardiovascular events, fatal and nonfatal, was recorded during the follow-up. During a median follow-up of 4.7 years (17 028 patients-year), 294 fatal and first nonfatal cardiovascular events were recorded (1.73 CVD per 100 patients/year). Independently of blood pressure, estimated glomerular filtration rate, level of cardiovascular risk, and antihypertensive treatment, microalbuminuria at baseline and at any time during the follow-up resulted in higher risk for events, hazard ratio (HR) 1.35 (95% confidence interval [CI], 1.08-1.79) and HR 1.49 (95% CI, 1.14-1.94), respectively. Likewise, development of microalbuminuria (HR 1.60; 95% CI, 1.04-2.46) or persistence from the beginning (1.53; 95% CI, 1.13-2.06) had a significantly higher rate of events than if remained normoalbuminuric (HR 1) or regress to normoalbuminuria (HR 1.37; 95% CI, 0.92-2.06) with an 18%, 18%, 8%, and 11% events, respectively, P<0.001. The study supports the value of urinary albumin excretion assessment as a prognostic factor for cardiovascular risk, but also opens the way to consider it as an intermediate objective in hypertension. © 2014 American Heart Association, Inc.

  18. Intracellular sodium concentration and transport in red cells in essential hypertension, hyperthyroidism, pregnancy and hypokalemia.

    Intracellular sodium content ([Nai]), ouabain-sensitive ('Na-K ATPase') and ouabain-insensitive ('passive permeability') sodium efflux, Na-K cotransport and Na-Li ('Na-Na') countertransport were estimated in erythrocytes in 39 control subjects, 20 patients with essential hypertension, 14 patients with hypokalemia of renal or unknown etiology, 13 hyperthyroid patients and 19 pregnant women. In normokalemic essential hypertension there was only a moderate, but significant elevation of the activity of the Na-Li countertransport system. In the group of patients with hypokalemia, there was a significant increase of [Nai], ouabain-insensitive sodium efflux and Na-Li countertransport. In hyperthyroidism, a marked decrease of Na-Li countertransport was associated with a marked elevation of [Nai], in pregnancy an elevation of the Na-Li countertransport with a [Nai] 43% lower than the control values. The ouabain-sensitive sodium efflux was elevated in hyperthyroidism and hypokalemia, in which [Nai] was increased. In the control subjects there was a positive linear correlation between ouabain-sensitive sodium efflux and [Nai]. The sodium component of the Na-K cotransport was decreased to about one third of the unchanged furosemide-sensitive potassium component during pregnancy. The changes of cellular sodium metabolism in essential hypertension are of minor degree as compared to those in the other conditions studied. Cellular sodium metabolism in blood cells is influenced by thyroid hormones and metabolic disorders. Na-Li countertransport, i.e. Na-Na countertransport, seems to be involved in the regulation of [Nai]: an increase of its activity diminishes [Nai] (pregnancy); a decrease elevates [Nai] (hyperthyroidism). Ouabain-sensitive sodium efflux, i.e. 'Na-K ATPase', is mainly regulated by its substrate, [Nai].

  19. The Impact of Vitamin D in the Treatment of Essential Hypertension

    Directory of Open Access Journals (Sweden)

    Christian Legarth

    2018-02-01

    Full Text Available The aim of this review is to investigate, whether there is a possible link between vitamin D supplementation and the reduction of blood pressure in hypertensive patients. The renin-angiotensin-aldosterone system is known for being deeply involved in cardiovascular tonus and blood pressure regulation. Hence, many of the pharmaceutical antihypertensive drugs inhibit this system. Interestingly, experimental studies in mice have indicated that vitamin D supplementation significantly lowers renin synthesis and blood pressure. It is conceivable that similar mechanisms may be found in the human organism. Regarding this, large-scale cross-sectional studies suggest the serum 25(OHD-level to be inversely correlated to the prevalence of hypertension. However, randomized controlled trials (RCTs have not found a clear association between vitamin D supplementation and improvements in hypertension. Nevertheless, the missing association of vitamin D and hypertension in clinical trials can be due to suboptimal study designs. There are hints that restoration of serum 25(OHD levels during vitamin D therapy is essential to achieve possible beneficial cardiovascular effects. It is important to perform long-term trials with a short dose interval and a high bioavailability of supplementation. Taken together, more RCTs are required to further investigate if vitamin D can be beneficial for the reduction of blood pressure.

    A number of studies show that atrial natriuretic peptide (ANP) raises renal sodium excretion with a concomitant increase in glomerular filtration rate (GFR) in both experimental animals and normal humans. Studies using indirect evaluation of GFR have provided less consistent results in hypertensive patients. We studied the effects of intravenously administered (iv) {alpha}-human ANP on GFR in patients with hypertension by a radionuclide technique using technetium 99m diethylenetriaminepenta-acetic acid. In six patients (ANP group), GFR was determined under control conditions, during iv ANP (initial bolus of 0.5 {mu}g/kg followed by a 21-min maintenance infusion at 0.05 {mu}g.kg{sup -1}.min{sup -1}) and during a recovery phase. In six other patients (control group), GFR was determined under control conditions, during saline iv infusion and during recovery. The two groups did not differ with respect to age, sex, basal blood pressure, heart rate or GFR. In the ANP group, the infusion of the peptide induced a significant decrease of mean blood pressure (from 133+-5 to 120+-5 mmHg, P<0.01), no change in heart rate and a significant increase in GFR (from 104+-4 to 125+-5 ml/min, P<0.01). During recovery, blood pressure, heart rate and GFR were not different from the values recorded under control conditions. No changes in blood pressure, heart rate or GFR (from 106+-5 to 108+-5 ml/min, n.s.) were detected during saline infusion in the control group. Our results demonstrated that in patients with essential hypertension, ANP induces an augmentation in GFR in spite of a decrease in blood pressure; this suggests a unique role for atrial peptide-related drugs in the treatment of human hypertension.

    AimIn essential hypertension (EH), the regulation of renal sodium excretion is aberrant. We hypothesized that in mild EH, (i) abnormal dynamics of plasma renin concentration (PRC) and atrial natriuretic peptide (ANP) are responsible for the exaggerated natriuresis, and (ii) exosomic protein...... patterns reflect the renal tubular abnormality involved in the dysregulation of sodium excretion. MethodsAfter 2-week drug washout and 4-day diet, systemic and renal hemodynamics, cardio-renal hormones, glomerular filtration and renal excretion were studied in male patients during saline loading (SL...

    Clinicians generally agree on the association between depression and hypertension. Less clear is if the nature of the link is direct or indirect and if this should be considered confined only to syndromal forms or if it concerns also subsyndromal affective presentations. This study investigated the nature of the association between hypertension and subsyndromal depression in hospitalized hypertensive patients. 196 hypertensive and 96 non hypertensive inpatients underwent a SCID interview, to exclude patients positive for any Axis I or Axis II diagnosis. Symptomatic Subsyndromal Depression (SSD) was identified according to criteria proposed by Judd. Psychopathological assessment was performed with Anxiety Sensitivity Index (ASI) and Hopkins Symptom Checklist-90 (SCL-90). Clinical assessments included blood pressure measurement, evaluation of general health conditions and screening cardiovascular risk factors (smoke, alcohol, body weight, sedentary life style). Hypertensives met more frequently criteria for SSD. They also scored higher on ASI and SCL-90. However, those with more severe physical conditions, if compared with more healthy patients, did not show increased psychopathological severity. Similarly, psychopathological symptom severity did not differ among hypertensives positive for other cardiovascular risk factors, commonly more frequent among depressed subjects. Further analyses are needed to explore the potential advantage obtained on blood pressure control by treating SSD. Hospitalized hypertensives, more frequently satisfied criteria for Symptomatic Subsyndromal Depression. These milder affective forms are probably directly linked to the presence of hypertension, rather than being indirectly associated to physical impairment or to higher prevalence of other cardiovascular risk factors.

Endothelial function is altered in patients with coronary artery disease, stroke, and peripheral artery disease, and endothelial dysfunction correlates with the risk factor profile for a patient. Hypertension and type 2 diabetes are risk factors for vascular disease, and are both pathologies characterized by loss of NO activity. Indeed, endothelial dysfunction is usually present in diabetic and/or hypertensive patients. Tetrahydrobiopterin is an essential cofactor for the NO synthase enzyme, and insufficiency of this cofactor leads to uncoupling of the enzyme, release of superoxide, endothelial dysfunction, progression of hypertension, and finally, proatherogenic effects. Tetrahydrobiopterin is also an important mediator of NO synthase regulation in type 2 diabetes and hypertension, and may be a rational therapeutic target to restore endothelial function and prevent vascular disease in these patients. The aim of this paper is to review the rationale for therapeutic strategies directed to biopterins as a target for vascular disease in type 2 diabetic hypertensive patients.Keywords: tetrahydrobiopterin, endothelial dysfunction, diabetes, hypertension, oxidative stress, nitric oxide, eNOS synthase uncoupling

    Severe arterial hypertension gathers relatively different clinical situations explained by the heterogeneity of the definitions of this clinical setting. From a medical point of view, severe hypertension is a short course situation defined by very high values of blood pressure corresponding to grade 3 hypertension. In France, until 2011, the social security also included in the definition of severe HTA chronic situations characterized by moderate blood pressure values requiring at least triple anthihypertensive therapies associated with a clinical or infraclinical target organ damages. These clinical profiles, much more frequent than grade 3 hypertension, allowed the full reimbursement of care costs for these patients. In France, it is estimated that 10% of hypertensive patients present a severe form with an annual incidence of 50,000 patients. The patients with severe hypertension have an increased cardiovascular morbidity justifying a closer clinical monitoring. From an economic point of view, these severe forms of hypertension have a higher cost of care, explained primarily by a more frequent need of specialized referrals, radiological exams and hospitalizations. This excess cost justified the existence of a full coverage of induced costs by the social security, since the incidence of severe hypertension is more frequent in the low social categories, and in patients with economic fragility.

    Full Text Available The pathogenesis of essential hypertension (EH is affected by genetic and environmental factors. Mutations in hypertension-related genes can affect blood pressure (BP via alteration of salt and water reabsorption by the nephron. The genes of the renin-angiotensin system (RAS have been extensively studied because of the well documented role of this system in the control of BP. It has been previously shown that Angiotensin II type 1 receptor (ATR1 gene polymorphism could be associated with increased risk of EH. So, in the current study, we evaluated the frequency of ATR1 (A1166C polymorphism in relation to EH in a group of Egyptian population. The study population included 83 hypertensive patients and 60 age and sex matched healthy control subjects. Restriction fragment length polymorphism – Polymerase chain reaction (RFLP – PCR was used for the analysis of A1166C polymorphism of ATR1 genes in peripheral blood samples of all patients and controls. The results revealed that there was a positive risk of developing EH when having the T allele whether in homozygous or heterozygous state. From this work, it was concluded that there was an association between ATR1 (A1166C gene polymorphism and the risk of developing EH.

    Nowadays, not only endurance training but also power training is recommended for patients with hypertension. In appropriately doses programs (no forced respiration), a number of studies have documented a blood pressure lowering effect. In the elderly hypertensive in particular, positive effects of power training that go beyond the simple lowering of elevated blood pressure may be expected.

  12. Essential hypertension in adolescents and children: Recent advances in causative mechanisms

    2011-01-01

    Full Text Available Essential hypertension is the most common form of hypertension in adults, and it is recognized more often in adolescents than in younger children. It is well known that the probability of a diagnosis of essential hypertension increases with age from birth onward. The initiation of high blood pressure burden starts in childhood and continues through adolescence to persist in the remaining phases of life. The genesis of essential hypertension is likely to be multifactorial. Obesity, insulin resistance, activation of sympathetic nervous system, sodium homeostasis, renin-angiotensin system, vascular smooth muscle structure and reactivity, serum uric acid levels, genetic factors and fetal programming have been implicated in this disorder. In addition, erythrocyte sodium transport, the free calcium concentration in platelets and leukocytes, urine kallikrein excretion, and sympathetic nervous system receptors have also been investigated as other possible mechanisms. Obesity in children appears to be the lead contributor of essential hypertension prevalence in children and adolescents. Suggested mechanisms of obesity-related hypertension include insulin resistance, sodium retention, increased sympathetic nervous system activity, activation of renin-angiotensin-aldosterone, and altered vascular function. The etiopathogenesis of essential hypertension in children and adolescents appears to closely resemble that of adults. The minor variations seen could probably be due to the evolving nature of this condition. Many of the established mechanisms that are confirmed in adult population need to be replicated in the pediatric age group by means of definitive research for a better understanding of this condition in future.

    Among patients with resistant hypertension (RHTN), there are those whose blood pressure (BP) remains uncontrolled in spite of maximal medical therapy. This retrospective analysis aims to characterize these patients with refractory hypertension. Refractory hypertension was defined as BP that remained uncontrolled after ≥3 visits to a hypertension clinic within a minimum 6-month follow-up period. Of the 304 patients referred for RHTN, 29 (9.5%) remained refractory to treatment. Patients with refractory hypertension and those with controlled RHTN had similar aldosterone levels and plasma renin activity (PRA). Patients with refractory hypertension had higher baseline BP (175±23/97±15 mm Hg vs 158±25/89±15 mm Hg; P=.001/.005) and heart rate, and higher rates of prior stroke and congestive heart failure. During follow-up, the BP of patients with refractory hypertension remained uncontrolled (168.4±14.8/93.8±17.7 mm Hg) in spite of use of an average of 6 antihypertensive medications, while those of patients with controlled RHTN decreased to 129.3±11.2/77.6±10.8 mm Hg. Spironolactone reduced the BP by 12.9±17.8/6.6±13.7 mm Hg in patients with refractory hypertension and by 24.1±16.7/9.2±12.0 mm Hg in patients with controlled RHTN. In patients with RHTN, approximately 10% remain refractory to treatment. Similar aldosterone and PRA levels and a diminished response to spironolactone suggest that aldosterone excess does not explain the treatment failure. © 2011 Wiley Periodicals, Inc.

    BAG3 is a member of human BAG (Bcl-2-associated athanogene) proteins and plays a role in apoptosis, cell adhesion, cytoskeleton remodeling, and autophagy. The aim of this study was to evaluate BAG3 levels in healthy subjects, hypertensive patients, and hypertensive diabetic patients. We enrolled 209 Caucasian adults, of both sex, 18-75 years of age, 77 were healthy controls, 62 were affected by hypertension, and 70 were affected by hypertension and type 2 diabetes. All patients underwent an assessment that included medical history, physical examination, vital signs, a 12-lead electrocardiogram, measurements of systolic (SBP), and diastolic blood pressure (DBP), heart rate (HR), fasting plasma glucose (FPG), glycated hemoglobin (HbA 1c ), triglycerides (TG), transaminases, high sensitivity C-reactive protein (Hs-CRP), and BAG3. We observed higher blood pressure values in hypertensive, and hypertensive diabetic patients compared to controls. As expected, FPG and HbA 1c were higher in diabetic hypertensive patients, compared to the other two groups. No Tg levels differences were recorded among the three groups. Hs-CRP was higher in diabetic hypertensive patients compared to healthy subjects. Finally, BAG3 levels were higher in hypertensives, and hypertensive diabetic patients compared to controls. We observed higher levels of BAG3 in hypertensive patients compared to healthy controls, and even higher levels in hypertensive diabetic patients compared to healthy subjects. This paper could be the first of a long way to identify potential involvement of deregulated BAG3 levels in cardiometabolic diseases. © 2017 Wiley Periodicals, Inc.

    Cerebral hemodynamics in 15 patients with hypertensive intracerebral hemorrhage (HICH) were evaluated by measuring cerebral blood flow (CBF) and cerebrovascular reserve capacity, using stable xenon-enhanced computed tomography. Their hematomas were removed by stereotactic aqua stream aspiration. The hemispheric and thalamic CBFs of patients with HICH were lower than those of hypertensive patients without hematomas. However, the hemispheric CBF increased according to how much of the hematoma was removed surgically. Thus, hemodynamics in patients with HICH can be improved by surgical hematoma removal, although some adjunct therapies are necessary in order to prevent secondary edema and the delayed neuronal death.

    The elemental concentrations in the blood of fully mature spontaneously hypertensive rats [SHR] were compared with that of normotensive Wistar Kyoto rats [WKy] with an energy- dispersive XRF-system using a Rhodium X-ray tube. A number of elements, Na, Mg, P, Cl, S, K, Ca, Fe, Cu, Zn, Rb and Br, ranging in concentrations from a few ppm to around 1 % were measured in all the blood samples. It has been observed that the concentrations of elements Na, Cu, Zn and Br in whole blood of SHR are about 5%, 17%, 7% and 21% higher respectively than in the WKy- group

    Masked hypertension (MH) is defined as a normal blood pressure in the physician's office and an elevated blood pressure when measured out-of-office. The cause of MH may be termed the masked hypertension effect (MHE), and is not restricted to blood-pressure (BP) values around the thresholds for normal BP. We investigated the prevalence and persistence of MH and MHE in patients who were being treated for high BP and who had been followed for a period of 1 year. One hundred and sixty-one treated hypertensive patients underwent office blood-pressure measurements (OBPMs) at seven visits and self-performed blood-pressure measurements (SBPMs) for 1 week before each visit over a period of 1 year. All measurements were performed with the same type of automatic device. At each visit, MH was determined according to the European Society of Hypertension definition (OBPM, /=135 mm Hg or 85 mm Hg). In addition, we determined prevalences of MHE at 5/3 mm Hg (SBPM exceeds OBPM by 5 mm Hg systolic and 3 mm Hg diastolic), and MHE at 10/6 mm Hg (SBPM exceeds OBPM by 10 mm Hg systolic and 6 mm Hg diastolic), respectively. During the entire study, 50% of the patients had MH, and 40% had MHE at 5/3 mm Hg at least once. At four sequential OBPM visits, 2% consistently had MH, and 3% had MHE at 5/3 mm Hg or MHE at 10/6 mm Hg. The prevalence of MH increased with lower OBPM levels but remained rather constant for MHE at 5/3 mm Hg and MHE at 10/6 mm Hg. The persistence of MH and the MHE over time in individual patients was low. We conclude that MH and MHE at 5/3 mm Hg and MHE at 10/6 mm Hg commonly occur in treated patients, but are not persistent phenomena and probably result from an accidentally low OBPM value on one particular occasion.

    Full Text Available Hypertension is China's leading cardiovascular disease risk factor. Improved hypertension control in China would result in result in enormous health gains in the world's largest population. A computer simulation model projected the cost-effectiveness of hypertension treatment in Chinese adults, assuming a range of essential medicines list drug costs.The Cardiovascular Disease Policy Model-China, a Markov-style computer simulation model, simulated hypertension screening, essential medicines program implementation, hypertension control program administration, drug treatment and monitoring costs, disease-related costs, and quality-adjusted life years (QALYs gained by preventing cardiovascular disease or lost because of drug side effects in untreated hypertensive adults aged 35-84 y over 2015-2025. Cost-effectiveness was assessed in cardiovascular disease patients (secondary prevention and for two blood pressure ranges in primary prevention (stage one, 140-159/90-99 mm Hg; stage two, ≥160/≥100 mm Hg. Treatment of isolated systolic hypertension and combined systolic and diastolic hypertension were modeled as a reduction in systolic blood pressure; treatment of isolated diastolic hypertension was modeled as a reduction in diastolic blood pressure. One-way and probabilistic sensitivity analyses explored ranges of antihypertensive drug effectiveness and costs, monitoring frequency, medication adherence, side effect severity, background hypertension prevalence, antihypertensive medication treatment, case fatality, incidence and prevalence, and cardiovascular disease treatment costs. Median antihypertensive costs from Shanghai and Yunnan province were entered into the model in order to estimate the effects of very low and high drug prices. Incremental cost-effectiveness ratios less than the per capita gross domestic product of China (11,900 international dollars [Int$] in 2015 were considered cost-effective.

    In order to investigate the relationship of different morbid states of the hypertrophied myocardium to the appearance of ventricular premature contraction (VPC), we compared the VPC findings from Holter ECG with those of UCG and stress thallium-201 myocardial SPECT scintigraphy (stress scinti) in 31 patients with hypertrophic cardiomyopathy (HCM) and 20 with essential hypertension (HT). The HCM patients consisted of 21 with asymmetric hypertrophy (ASH), 3 with symmetric hypertrophy (SH), and 7 with apical hypertrophy (APH). We recognized positive findings on the stress scinti such as fixed perfusion defect (FD) or reversible perfusion defect (RD) in 11 patients (ASH 10, APH 1) out of 31 patients with HCM (35%). Positive findings were observed in only one patient out of 20 with HT (5%). We recognized a high grade VPC (grade 4a and 4b of Lown's criteria) in 8 of 11 scinti positive patients with HCM (ASH 7, APH 1)(73%), while high grade VPC appeared in 5 (all of them are ASH) out of 20 scinti negative patients with HCM (25%). Therefore, these findings suggest that high grade VPCs in HCM occur in relation to a myocardial perfusion defect. (author)

    Red cell cation transport has been studied in normotensive and essential hypertensive groups of white and black (West Indian) subjects. In vitro uptake of the potassium analogue 86Rb was measured during short-term incubation of erythrocytes in the presence and absence of ouabain. Sodium pump activity was significantly greater (p less than 0.0005) in white hypertensives than in white normotensives. No such difference was observed between black hypertensive and normotensives. 86Rb uptake was significantly lower in black than in white normotensive individuals; this racial differences was not due to a difference in sodium pump activity

    Based on the western medication, to evaluate the advantages in the morning blood pressure treated with acupuncture at Fengchi (GB 20) and Neck-Jiaji (EX-B 2) combined with acupuncture technique for activating blood circulation, eliminating wind and regulating the liver and spleen in the patients with essential hypertension. A total of 90 patients of essential hypertension of the mild and moderate degrees were randomized into a medication group (30 cases, 3 dropping), No.1 acupuncture group (30 cases, 2 dropping) and No.2 acupuncture group (30 cases, 1 dropping). In the medication group, adalat was prescribed for oral administration, 30 mg at 7 am every day, continuously for 6 weeks. In the No.1 acupuncture group, on the basis of the treatment as the medication group, the acupuncture technique for activating blood circulation, eliminating wind and regulating the liver and spleen was applied and the acupoints were Renying (ST 9), Hegu (LI 4), Taichong (LR 3), Quchi (LI 11) and Zusanli (ST 36). In the No.2 acupuncture group, on the basis of the treatment as the No.1 acupuncture group, Fengchi (GB 20) and Neck-Jiaji (EX-B 2) were added in acupuncture. Acupuncture was given in the time zone from 8 am through 10 am every day, once a day, 5 times a week, totally for 6 weeks. Separately, before treatment and in 2, 4 and 6 weeks of treatment, the morning blood pressure, the control rate and the symptom score were observed in the patients of the three groups. The morning blood pressure was followed up in 3 and 6 months separately. Compared with those before treatment, in 2, 4 and 6 weeks of treatment, the levels of blood pressure reduced in the patients of the three groups ( P blood pressure and its control rate in the patients of the three groups (all P >0.05). In 4 and 6 weeks of treatment, the levels of the morning blood pressure in the No.2 acupuncture group were lower than those in the No.1 acupuncture group, and the results in the No.1 and No.2 acupuncture groups were

    Emerging evidence suggests that the soluble receptor for advanced glycation end-products (sRAGE) is implicated in the development of vascular disease. We investigated the interrelationships of sRAGE with albumin to creatinine ratio (ACR) and arterial stiffness in essential hypertension. In 309 untreated non-diabetic hypertensives, ACR values were determined as the mean of three non-consecutive morning spot urine samples and aortic stiffness was evaluated on the basis of carotid to femoral pulse wave velocity (c-f PWV). In all subjects, venous blood sampling was performed for the estimation of sRAGE levels. Patients with low (n = 155) compared to those with high sRAGE values (n = 154) had greater 24-h systolic BP (140 ± 8 vs. 134 ± 7 mmHg, p involvement of sRAGE in the progression of hypertensive vascular damage.

    To assess the knowledge of the hypertensive patients about their hypertension and their relation to its control. Cross-sectional study among 400 hypertensive patients, all over 18 years, selected from 50 primary-care centres, who responded to an hypertension-related survey. Included variables were survey items, age, gender, educational level, professional occupation, blood pressure data and antihypertensive treatment. The obtained differences were analyzed using the chi-square test, Kruskal-Wallis, Wilcoxon, Anova and Bonferroni methods. There were 323 valid surveys. 52.9% of respondents were women, the average age: 65.4 years (SD: 11.2), 54.8% of them had primary education. 39.6% were aware of the objectives of systolic BP control. Only 19.6% having knowledge of those for diastolic BP control, with no differences between controlled and uncontrolled (systolic BP: 39% vs 38.1%, P=.887; diastolic BP: 19.2% vs 21%, P=.721). Over 70% knew about lifestyle changes, without significant differences between controlled and uncontrolled respondents. 82% of controlled respondents, and 79% of those uncontrolled, recognized the chronical nature of the treatment (P=.548), but 15.1% of the controlled respondents and 12.4% of uncontrolled respondents did not see the relation between the treatment and hypertension control (P=.525). 31.1% believed to be well-controlled, but in fact was not. Our patients doesn't know blood pressure targets of control. There isn't relationship between this knowledge and control of hypertension. Copyright © 2014 SEHLELHA. Published by Elsevier Espana.

    Is continuous positive airway pressure (CPAP) therapy better than no therapy in reducing the incidence of hypertension or cardiovascular (CV) events in a cohort of nonsleepy patients with obstructive sleep apnea (OSA)? Randomized, controlled trial; no placebo CPAP used. ClinicalTrials.gov Identifier: NCT00127348. Randomization was performed using a computer generated list of random numbers in the coordinating center and results were mailed to participating centers in numbered opaque envelopes. Primary outcome was evaluated by individuals not involved in the study and who were blinded to patient allocation. Patients, investigators, and the statistician were not blinded. median 4 (interquartile range, 2.7-4.4) years. 14 academic medical centers in Spain. 725 adults (mean age 51.8 y, 14% women) who were diagnosed with OSA with apnea hypopnea index (AHI) ≥ 20 events per hour and Epworth sleepiness score (ESS) ≤ 10 were randomized. Subjects with previous CV events were excluded. However, patients with a history of hypertension were not excluded (50% of the sample were hypertensive at baseline). Patients were randomized to receive CPAP treatment or no active intervention. All participants received dietary counseling and advice about sleep hygiene. The primary outcome was the incidence of either systemic hypertension (among participants who were normotensive at baseline) or CV events (among all participants). The secondary outcome was the association between the incidence of hypertension or CV events (nonfatal myocardial infarction, nonfatal stroke, transient ischemic attack, hospitalization for unstable angina or arrhythmia, heart failure, and CV death) and the severity of OSA assessed by the AHI and oxygen saturation. The sample size was calculated assuming that the incidence of hypertension or new CV event in this population over a period of 3 years would be 10% annually; 345 patients per group were needed to detect a 60% reduction in incidence of new hypertension

    Exertional dyspnoea is a leading symptom in patients with pulmonary arterial hypertension (PAH). Patients suffering from PAH report poor quality of life, have skeletal muscle dysfunction and in the absence of advanced medical therapy deteriorate progressively due to right heart failure which can lead to death. For decades, patients with PAH were advised to avoid exercise in fear of exacerbated right heart failure. Recently, it has been shown that a highly supervised rehabilitation programme in expert centres leads to significant improvements in symptoms, quality of life, exercise capacity and may even enhance haemodynamics in selected stable patients treated with advanced regimens of PAH-targeted drugs. As a consequence of these promising results, pulmonary rehabilitation performed in an expert centre has been included in recent guidelines. The underlying mechanisms are not completely understood, but positive effects can be measured in different organ systems such as skeletal muscles, the cardiopulmonary system and immune system (inflammation), and also on the psychological level. Thus, improvements in 6-minute walking distance (6MWD), peak oxygen uptake (VO2 peak), muscle strength and muscle endurance, as well as physical and mental quality of life scores (SF-36 questionnaire) have been shown. Different training protocols have been used. Essential are qualified patient selection in expert centres, a low workload endurance and dumbbell (weight lifting) training avoiding strenuous exercise and exhaustion, thorough patient education and close supervision by experts especially during the first weeks. Adverse events may occur (e.g., pre-/syncope, arrhythmia, respiratory infections). PAH patients tend to overestimate their physical capacity, not perceiving their own limits properly, which makes education and expert advice even more important as exercise training can also worsen the right heart failure. Therefore, a core issue of the multidisciplinary rehabilitation is

    Most optimally treated hypertensive patients still have an around 50% increased risk of any cardiovascular event, suggesting the possible existence of unidentified risk factors. In the last years there has been evidence of the essential role of circulating endothelial progenitor cells (EPCs) in the maintenance of endothelial integrity and function, increasing the interest in their involvement in cardiovascular disease. In this study, the circulating levels of EPCs and vascular endothelial growth factor (VEGF) are investigated in treated hypertensive patients with adequate control of blood pressure (BP). Blood samples were collected from treated hypertensive patients with controlled BP. Plasma levels of EPCs CD34+/KDR+ and CD34+/VE-cadherin+ were quantified by flow cytometry. Plasma concentration of VEGF was determined by ELISA. A group of healthy subjects without cardiovascular risk factors was included as controls. A total of 108 hypertensive patients were included (61±12 years, 47.2% men) of which 82.4% showed BP<140/90 mmHg, 91.7% and 81.5% controlled diabetes (HbA1c <7%) and cLDL (<130 or 100 mg/dL), respectively, and 85.2% were non-smokers. Around 45% of them were obese. Although patients had cardiovascular parameters within normal ranges, they showed significantly lower levels of CD34+/KDR+ and CD34+/VE-cadherin+ compared with healthy control group, although plasma VEGF concentration was higher in patients than in controls. Despite an optimal treatment, hypertensive patients show a decreased number of circulating EPCs that could be, at least in part, responsible for their residual cardiovascular risk, suggesting that these cells could be a therapeutic target.

    Autonomic failure (AF) is characterized by orthostatic hypotension, supine hypertension, and increased blood pressure (BP) variability. AF patients develop cardiac organ damage, similarly to essential hypertension (EH), and have higher arterial stiffness than healthy controls. Determinants of cardiovascular organ damage in AF are not well known: both BP variability and mean BP values may be involved. The aim of the study was to evaluate cardiac organ damage, arterial stiffness, and central hemodynamics in AF, compared with EH subjects with similar 24-hour BP and a group of healthy controls, and to evaluate determinants of target organ damage in patients with AF. Twenty-seven patients with primary AF were studied (mean age, 65.7±11.2 years) using transthoracic echocardiography, carotid-femoral pulse wave velocity, central hemodynamics, and 24-hour ambulatory BP monitoring. They were compared with 27 EH subjects matched for age, sex, and 24-hour mean BP and with 27 healthy controls. AF and EH had similar left ventricular mass (101.6±33.3 versus 97.7±28.1 g/m(2), P=0.59) and carotid-femoral pulse wave velocity (9.3±1.8 versus 9.2±3.0 m/s, P=0.93); both parameters were significantly lower in healthy controls (Phypertensive heart disease and increased arterial stiffness, similar to EH with comparable mean BP values. Twenty-four-hour and nighttime systolic BP were determinants of cardiovascular damage, independent of BP variability. © 2015 American Heart Association, Inc.

    Circulating microRNAs (miRNAs) are promising biomarkers for many diseases. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) is a gold standard for miRNA expression profiling that requires proper data normalization. Since there is no universal normalizer, it is recommended to evaluate normalizers under every experimental condition. This study describes the identification of suitable endogenous normalizer(s) (ENs) for plasma miRNA expression in essential hypertension. Expression levels of 5 candidate ENs and 2 plasma quality markers were determined by qRT-PCR in plasma samples from 18 hypertensive patients and 10 healthy controls. NormFinder, GeNorm, and DataAssist software programs were used to select the best EN(s). Expression levels of the 5 candidate ENs were also analyzed in urine samples from hypertensive patients and compared to the plasma samples of the hypertensive patients. Among the analyzed candidates, hsa-miR-92a-3p was identified as the best EN, and hsa-miR-21-5p and hsa-miR-16-5p as next best. Moreover, hsa-miR-92a-3p showed the most consistent expression between plasma and urine In conclusion, this study showed that hsa-miR-92a-3p, hsa-miR-21-5p, and hsa-miR-16-5p may be used as normalizers for plasma miRNA expression data in essential hypertension studies.

    The aim of our study was to estimate brain perfusion and cognitive function (CF) in patients with arterial hypertension (AH) before and after hypotensive therapy. The study included 15 patients (mean age, 53.0±5.7 years) with previously untreated or ineffectively treated essential hypertension of the second degree. All patients underwent brain single photon emission computed tomography (SPECT) scanning with 99m Tc-hexamethylpropylene amine oxime ( 99m Tc-HMPAO) and comprehensive neuropsychological testing before and after 24 weeks of hypotensive therapy (angiotensin-converting enzyme [ACE] inhibitor or diuretics). The brain perfusion was significantly lower (15-22%) in all regions of AH patients. These patients showed a 25% decrease in attention and psychomotor speed as well as a 14% decrease in mentation. Six months of hypotensive therapy led to an increase in brain perfusion by an average of 7-11% in all brain regions. After treatment these patients demonstrated an average 11-18% improvements in attention and psychomotor speed, as well as an average 10% improvement in abstract mentation. Marked signs of brain hypoperfusion and impaired CF: decrease in attention, slowing psychomotor speed and mentation was found in hypertensive patients even without focal neurological symptomatology. Twenty-four weeks of hypotensive treatment with ACE inhibitors or diuretics had a positive effect on cerebral perfusion and led to CF improvement. (author)

    Now a day, hypertension is more increasing in frequency and ranked the top of the causes of death in Korea and other nations. Most of cerebrovascular accidents in hypertensive patients are composed of vascular occlusive changes and hemorrhages. In cerebral angiogram, we can only detect occlusion of large artery and large mass effect from hematoma or cerebral infarction without identification of its entity. The computed tomogram, however, is the best way for evaluation of cerebrovascular diseases including detection of nature, location, amount, and associated changes. This study includes evaluation of computed tomograms of 106 patients with hypertension during the period of 17 months from Feb. 1979 to June 1980 in the department of radiology, college of Medicine, Hanyang University. The results were as follows. 1. Age distribution of the total 106 patients was broad ranging from 25 years to 76 years. 67.9% of patients were over the age of 50. The male and female sex ratio was 3:2. 2. 28 out of 106 patients were normal and 78 patients revealed abnormal on C. T. findings; those were intracranial hemorrhage (35 patients), cerebral infarction (32 patients) and brain atrophy (11 patients). 3. All of the intracranial hemorrhage except one were intracerebral hemorrhage; those were located in the cerebral hemisphere (19 patients), basal ganglia (15 patients) and brain stem (1 patient). The except one case of intracranial hemorrhage was subdural hematoma. 7 patients of intraventricular hemorrhage and 1 patient of subarachnoid hemorrhage were combined with intracerebral hemorrhage. 2/3 of patients who had hemorrhage in cerebral hemisphere revealed lesions in the parietal and temporal lobes. 4. In cases of cerebral infarction, the cerebral hemisphere was most common site of lesion (20 cases), and the next was basal ganglia (11 cases). Most of the infarcts in cerebral hemisphere were located in the parietal and temporal lobes. The left basal ganglia was more commonly involved

    The aim of the study is to determine the frequency of pulmonary hypertension in patients with hepatic cirrhosis and portal hypertension, to determine the possibility of an accurate ultrasound diagnosis of the characteristics of this complication. 347 patients with liver cirrhosis consecutively hospitalized at Coltea Clinical Hospital were screened. 61 were excluded because of other possible causes of portal or pulmonary hypertension. All patients were investigated clinically and by abdominal and cardiac ultrasonography. Of the remaining 286 patients, 116 had portal hypertension, 27 of them (23%) having pulmonary hypertension. In this group we found a higher cardiac index and right atrial volume, higher pressures in the right atrium, suggesting a hyperdynamic state. Porto-pulmonary hypertension was found in only one patient. Echocardiography permits characterization of patients with cirrhosis and portal hypertension.

    In order to explore the clinical value of insulin (INS) and C - peptide (C-P) in essential hypertension patients (EH), concentrations of blood glucose, serum INS and serum C - P both during fasting and 2 - hour postprandial time were measured in 32 non-diabetic patients with EH and 40 healthy persons, and the ISI of each group was calculated and compared. The results showed that with the exception of fasting blood glucose level being of no difference between two groups, all the other parameters observed, including concentrations of 2 hour postprandial glucose, both fasting and 2 hour postprandial INS and C - P were significantly higher than those of healthy control group (P < 0.01). The proportions of patients with insulin resistance and hyperinsulinemia in EH group were both significantly higher than those of control group (P < 0.01). These results suggest that EH patients may coexist with some metabolic disorders at the same time, thus INS and C - P detection may have other wider applications in non-diabetic diseases

    Radio-isotopic splenoportography was performed by injecting 99m TcO 4 - into the spleens of 46 patients with portal hypertension and 14 patients with various disorders not having portal hypertension. No collateral circulation was demonstrated in the 14 patients without portal hypertension whereas some RI-images of portosystemic collaterals were found in 40 (87.0 per cent) of the 46 patients with portal hypertension. Collaterals were divided into an ascending group and a descending group, the appearance rate of ascending collaterals being 80.4 per cent and that of descending collaterals, 41.3 per cent. There were 3 image patterns in the ascending group, namely, an AZ-pattern in which the azygos vein was demonstrated; a SC-pattern in which the RI-bolus ascended along the esophagus to the neck and the subclavian vein; and an EG-pattern which showed stagnation of the RI-bolus in the esophagogastric region. There were 4 patterns in the descending group, namely; a pattern of gastro-renal caval shunt (GR-pattern); reverse flow patterns into the umbilical or paraumbilical veins (UV-pattern); into the superior mesenteric vein (SMV-pattern); and into the inferior mesenteric vein (IMV-pattern). The appearance of the EG-pattern was seen most frequently (74.4 per cent). The usefulness of this method for surveying the collateral circulation in portal hypertension, estimating the risk of esophageal variceal bleeding and evaluating its treatments, was suggested by the results of this study.

    Hypertension has a multi-factorial background based on genetic and environmental interactive factors. ACE, FABP2 and GST genes have been suggested to be involved in the development of hypertension. However, the results have been inconsistent. The present study was carried out to investigate the association of ACE (rs4646994), FABP2 (rs1799883) and GST (GSTM1 null or positive genotype and GSTT1 null or positive genotype) genes polymorphism with essential HTN cases and controls. This study includes 138 essential hypertension (HTN) patients and 116 age-, sex- and ethnicity-matched control subjects. GST (GSTM1 null or positive genotype and GSTT1 null or positive genotype) genes polymorphisms were evaluated by multiplex PCR, ACE (rs4646994) gene polymorphisms by PCR and FABP2 (rs1799883) gene polymorphisms by PCR-RFLP method. Significant differences were obtained in the frequencies of ACE DD, II genotype (p = 0.006, 0.003), GSTT1 null, GSTM1 positive genotype (p = 0.048, 0.010) and FABP2 Ala54/Ala54 genotype (p = 0.049) between essential HTN cases and controls. It is concluded that ACE (rs 4646994), FABP2 (rs1799883) and GST (GSTM1 null or positive genotype and GSTT1 null or positive genotype) genes polymorphism are associated with HTN. Further investigation with a larger sample size may be required to validate this study.

    Considering high prevalence and the need to look for alternative medicine, essential hypertension was screened in light of Vata-Pitta Pradhana Rakta Pradoshaja Vikara as mentioned by Acharya Charaka. Comparing the etiological factors, symptomatology, and complications with Rakta Pradoshaja Vikara with that of essential hypertension, a striking similarity was revealed. To prove the practical approach of management of Vata-Pitta Pradhana Rakta Pradoshaja Vikara, a randomized open clinical trial on 33 uncomplicated subjects of essential hypertension was conducted. The subjects were allotted in two groups, viz. (Group A) Virechana group having 16 cases who underwent Virechana Karma by Trivrita, Aragvadha, Eranda Taila, and Draksha Kwatha as Sahapana; and (Group B) Basti group consisting of 17 cases who were administered Dashmoola Kala Basti in which Niruha with Dashmoola Kwatha and Anuvasana with Dashmoola Taila was done. Patients of both the groups were followed by Shamana Chikitsa (Arjunadi Ghanavati). The overall effect of the therapies on systolic and diastolic blood pressure showed that Virechana proved better relief (43.75%) as compared to Basti (29.41%). The response was encouraging and has created scope for further studies.

    Psychosocial factors play an important role in the development and course of essential hypertension, although "stress" can account for only 10% of blood pressure variance. A variety of psychotherapeutic interventions, such as relaxation techniques (autogenic training or progressive muscular relaxation), behavioral therapy or biofeedback techniques, can lower elevated blood pressure by an average of 10 mmHg (systolic) and 5 mmHg (diastolic). As a "secondary effect", such measures may also prompt the hypertensive to adopt a more health-conscious lifestyle.

    Full Text Available Thorsten Reffelmann, Robert A KlonerUniversity of Southern California, The Heart Institute, Good Samaritan Hospital, Division of Cardiovascular Medicine, Keck School of Medicine, Los Angeles, CA, USAAbstract: In many forms of erectile dysfunction (ED, cardiovascular risk factors, in particular arterial hypertension, seem to be extremely common. While causes for ED are related to a broad spectrum of diseases, a generalized vascular process seems to be the underlying mechanism in many patients, which in a large portion of clinical cases involves endothelial dysfunction, ie, inadequate vasodilation in response to endothelium-dependent stimuli, both in the systemic vasculature and the penile arteries. Due to this close association of cardiovascular disease and ED, patients with ED should be evaluated as to whether they may suffer from cardiovascular risk factors including hypertension, cardiovascular disease or silent myocardial ischemia. On the other hand, cardiovascular patients, seeking treatment of ED, must be evaluated in order to decide whether treatment of ED or sexual activity can be recommended without significantly increased cardiac risk. The guideline from the first and second Princeton Consensus Conference may be applied in this context. While consequent treatment of cardiovascular risk factors should be accomplished in these patients, many antihypertensive drugs may worsen sexual function as a drug specific side-effect. Importantly, effective treatment for arterial hypertension should not be discontinued as hypertension itself may contribute to altered sexual functioning; to the contrary, alternative antihypertensive regimes should be administered with individually tailored drug regimes with minimal side-effects on sexual function. When phosphodiesterase-5 inhibitors, such as sildenafil, tadalafil and vardenafil, are prescribed to hypertensive patients on antihypertensive drugs, these combinations of antihypertensive drugs and

    Scintiphotosplenoportograpy (SSP) was performed in five normals and 25 patients with portal hypertension using Tc-99m tin colloid. 12 patients were cirrhotic and 13 had idiopathic portal hypertension (IPH). Analogue and fast frame dynamic studies were performed and subsequently processed. Intra hepatic shunt index in cirrhotics was significantly different from the IPH group. Extra hepatic shunt index, however, was not significantly different in the two groups but was related more to the severity of the disease process. Spleno hepatic and spleno cardiac transit times were significantly lower cirrhotics as compared to the IPH group. We conclude that SSP is a technically simple, rapid and a much less invasive method of visualizing the portal circulatory system and assessing the portal haemo dynamics. it also provides clinically important measure of shunted blood nd allows for the quantification of circulatory time from spleen to liver and heart.

    Full Text Available Hypertension is a common disease associated with important cardiovascular complications. Persistent blood pressure of 140/90 or higher despite combined use of a reninangiotensin system blocker, calcium channel blocker and a diuretic at highest tolerated doses constitutes resistant hypertension. Excess sympathetic activity plays an important pathogenic role in resistant hypertension in addition to contributing to the development of metabolic problems, in particular diabetes. Reduction of renal sympathetic activity by percutaneous catheter-based radiofrequency ablation via the renal arteries has been shown in several studies to decrease blood pressure in patients with resistant hypertension, and importantly is largely free of significant complications. However, longer term follow-up is required to confirm both long-term safety and efficacy.

    We sought to understand barriers to hypertension self-management in patients with hypertension and comorbidities. We conducted semi-structured, qualitative interviews with 48 patients with uncontrolled hypertension and at least one comorbidity to learn about beliefs and behaviors that might affect hypertension self-management. Using a grounded theory strategy, we analyzed interview transcripts detailing patients' hypertension self-management behaviors vis-à-vis a framework including Explanatory Models-a patient's understanding of the pathophysiology, cause, course, treatment, and severity of an illness, such as hypertension. We identified four factors that interfered with hypertension self-management. (1) Interdependence: Participants saw hypertension as interconnected to their comorbidities and subsequently had difficulty separating information about their illnesses. (2) Low priority: Compared to other conditions, participants assigned hypertension a lower priority. (3) Conflicts: Participants struggled with conflicts between hypertension self-management practices and those for comorbidities. (4) Managing multiple medications: Polypharmacy led to patients' confusion and concern about taking medications as prescribed. Participants did not experience hypertension as a discreet clinical condition; rather, they self-managed hypertension concurrently with other conditions, leading to a breakdown in hypertension self-management. We provide strategies to address each of the four barriers to better equip providers in addressing their clinically salient concerns.

    Pulmonary arterial hypertension (PAH) is a disorder defined by elevated mean pulmonary arterial pressure. PAH can be idiopathic or associated with a variety of medical conditions such as scleroderma, congenital heart disease, left heart failure, lung disease or chronic pulmonary thromboembolism. This progressive disease can cause severe right heart failure and death. Normal physiologic changes that occur during pregnancy may produce fatal consequences in PAH patients. Current guidelines recommend that pregnancy be avoided or terminated early in women with PAH. During the past decade, new advanced therapies for PAH have emerged gathering reports of successful pregnancies in patients with pulmonary hypertension. Substantial risk still exists and current recommendations have not changed. Nevertheless, in selected cases, if a patient insists on continuing the pregnancy, being fully aware of the risks involved, an intensive treatment approach should be implemented in experienced centers. This is necessary in order to control pulmonary hypertension during pregnancy and reduce the risk so as to improve outcomes. This review will focus on the pathophysiology of PAH in pregnancy and appropriate management during pregnancy, delivery and the post-partum period.

    The renal circulation of patients with essential hypertension and renovascular hypertension was evaluated using 99m Tc-DTPA. The first renal peak count (the first C max ; FC max ), time phase distribution (the first T max ; FT max ), and blood velocity (the FC max /FT max ) were calculated by digital imaging. This yields a visual image of the renal circulation. We consider that the increase in the renal first pass blood flow in patients with essential hypertension is best observed pixel by pixel. The FC max and FC max /FT max images before and after treatment by percutaneous transluminal renal angioplasty in patients with renovascular hypertension clearly show its therapeutic effect. The FI technique, therefore, has the advantage that it can be performed at the same time as the conventional routine examinations of renal function. This makes it very useful clinically. (orig.)

    Full Text Available With-no-lysine (K Kinase-4 (WNK4 consisted of unique serine and threonine protein kinases, genetically associated with an autosomal dominant form of hypertension. Argumentative consequences have lately arisen on the association of specific single nucleotide polymorphisms of WNK4 gene and essential hypertension (EHT. The aim of this study was to determine the association of Ala589Ser polymorphism of WNK4 gene with essential hypertensive patients in Malaysia. WNK4 gene polymorphism was specified utilizing mutagenically separated polymerase chain reaction (PCR and restriction fragment length polymorphism (RFLP method in 320 subjects including 163 cases and 157 controls. Close relation between Ala589Ser polymorphism and elevated systolic and diastolic blood pressure (SBP and DBP was recognized. Sociodemographic factors including body mass index (BMI, age, the level of fasting blood sugar (FBS, low density lipoprotein (LDL, and triglyceride (TG in the cases and healthy subjects exhibited strong differences (p<0.05. The distribution of allele frequency and genotype of WNK4 gene Ala589Ser polymorphism showed significant differences (p<0.05 between EHT subjects with or without type 2 diabetes mellitus (T2DM and normotensive subjects, statistically. The WNK4 gene variation influences significantly blood pressure increase. Ala589Ser probably has effects on the enzymic activity leading to enhanced predisposition to the disorder.

    Essential hypertension (EH) is a common disease with a clear genetic component. Inflammation and endothelial dysfunction play a prominent role in the development of persistent blood pressure elevation. The aim of the current study was to detect an association between EH and polymorphic markers in genes encoding for molecules involved in the control of intercellular interactions during the inflammation process. We analysed SNPs in SELE, SELP, SELL, ICAM1, VEGFA, IL1B, IL6, IL10 and IL12B genes in a group of 534 men of Tatar ethnicity (217 patients with EH and 317 controls). Using a Markov chain Monte-Carlo-based approach (APSampler), we found genotype and allelic combinations associated with EH. The most significant associations were observed for SELE rs2076059*C-SELP rs6131*A-VEGFA -2549*I-IL1B rs16944*C (p = 3.42 × 10(-5), FDR q = 0.035) and SELE rs2076059*C-SELP rs6131*A-IL12B rs3212227*C-IL1B rs16944*C (p = 323 × 10(-4), FDR q = 0.035).

Part 1 of this study was the randomized, multicenter, double-blind, parallel group, Phase III, 8-week clinical trial to compare superiority of lercanidipine 10 mg/valsartan 80 mg (L10/V80) and lercanidipine 10 mg/valsartan 160 mg (L10/V160) combinations with lercanidipine 10 mg (L10) monotherapy. At screening, hypertensive patients, whose diastolic blood pressure (DBP) was >90 mm Hg after 4 weeks with L10, were randomized to 3 groups of L10, L10/V80, and L10/V160. The primary end point was the change in the mean sitting DBP from baseline (week 0) after 8 weeks of therapy. Patients who were randomly assigned to L10/V160 and whose mean DBP was still ≥ 90 mm Hg in part 1 were enrolled to the up-titration extension study with lercanidipine 20 mg/valsartan 160 mg (L20/V160) (part 2). Of 772 patients screened, 497 were randomized to 3 groups (166 in the L10 group, 168 in the L10/V80 group, and 163 in the L10/V160 group). Mean (SD) age was 55 (9.9) years, and male patients comprised 69%. The mean (SD) baseline systolic blood pressure (SBP)/DBP were 148.4 (15.1)/94.3 (9.5) mm Hg. No significant differences were found between groups in baseline characteristics except the percentages of previous history of antihypertensive medication. The primary end points, the changes of mean (SD) DBP at week 8 from the baseline were -2.0 (8.8) mm Hg in the L10 group, -6.7 (8.5) mm Hg in L10/V80 group, and -8.1 (8.4) mm Hg in L10/V160 group. The adjusted mean difference between the combination groups and the L10 monotherapy group was -4.6 mm Hg (95% CI, -6.5 to -2.6; P < 0.001) in the L10/V80 group and -5.9 mm Hg (95% CI, -7.9 to -4.0, P < 0.001) in the L10/V160 group, which had significantly greater efficacy in BP lowering. A total of 74 patients were enrolled in the part 2 extension study. Changes of mean

    This double-blind, double-dummy clinical trial evaluated the efficacy and safety of two strengths of fixed-dose combination of amlodipine/benazepril in Chinese hypertensive patients not adequately controlled with benazepril. Of 442 patients who received treatment with benazepril 10 mg for 4 weeks, 341 patients failed to achieve to diastolic blood pressure (DBP) benazepril 2.5/10 mg, or amlodipine/benazepril 5/10 mg, or benazepril 10 mg for 8 weeks. BP reductions with amodipinel/benazepril 2.5/10 mg (15.2/11.8 mmHg) or amlodipine/benazepril 5/10 mg (15.4/12.4 mmHg) were significantly greater than that with benazepril 10 mg (9.88/9.46 mmHg) at study end (p benazepril). BP control rate was 83.8% with amlodipine/benazepril 2.5/10 mg, 80.2% with amlodipine/benazepril 5/10 mg, 64.9% with benazepril 10 mg at study end (p benazepril). Three groups were generally well tolerated. Our study indicated that amlodipine/benazepril fixed-dose combination offered significant additional BP reductions and BP control rate compared with the continuation of benazepril monotherapy. No significant differences were observed in both BP reductions and BP control rate between amlodipine/benazepril 2.5/10 mg and amlodipine/benazepril 5/10 mg.

    Memory impairment, headaches and vertigo are considered as initial appearances of chronic cerebral vascular disorder in patients with arterial hypertension (AH). The complex analysis of complaints, cognitive functioning, emotional state and MRI data was conducted in 60 patients with AH, mean age 58,4+/-7,8 years, without a history of stroke and 30 controls matched for age, sex and education. Impairment of cognitive functioning was assessed by the Psychiatric Status Scale (a short version), the Clock Drawing Test, tests of auditory and verbal memory, attention concentration, speed of test performance, speech fluency and spatial orientation. The deterioration effect of systolic arterial pressure on cognitive functioning was found. The lesions of white matter (subcortical and/or periventricular leucoaraiosis) were observed in 76% of patients and single asymptomatic lacunar infarctions--in 20%. Cerebral vascular lesions were correlated with cognitive impairment. Anxiety and anxiety-depressive disorders which were not associated with the cerebral vascular lesion but related in large to the patient's complaints on headaches and vertigo were revealed in 62% of cases. The results of the study suggest that cognitive dysfunction proves to be the early and reliable predictor of chronic cerebral vascular disorder in patients with arterial hypertension.

    Chronic thromboembolic pulmonary hypertension (CTEPH) is thought to be a rare complication of pulmonary embolism. However, it was recently demonstrated that CTEPH is more common than previously thought after pulmonary embolism. Without treatment, CTEPH is associated with a very high mortality rate. Making the correct diagnosis early is essential, because there is a potential curative treatment in the form of pulmonary thromboendarterectomy (PTE). Because of the unspecific clinical symptoms of CTEPH, the different imaging modalities play a crucial role in diagnosis making. Since the introduction of the multi-detector CT technology, CT has become an important part in the diagnostic work up of pulmonary embolism and CTEPH and is often used as a first-line diagnostic tool. CT is not only a reliable tool for the diagnosis of CTEPH, but also is helpful in estimating the operability of these patients. PTE is still associated with a mortality rate of about 10%. Particularly an insufficient decrease of the pulmonary vascular resistance after PTE leads to a very high mortality rate. Therefore, it is crucial to correlate the degree of the surgical accessible obstruction of the pulmonary vasculature with the degree of pulmonary hypertension in deciding for or against PTE. The aim of this review is to describe the CT findings in patients with CTEPH and their use in differentiating CTEPH from other diseases like acute pulmonary embolism and primary pulmonary hypertension. Moreover, the correlation of different CT imaging features with surgical success after PTE will be discussed. (orig.)

    The objective was to assess the impact of weight changes on blood pressure (BP), lipids and glucose goals in a cohort of hypertensive subjects. Prospective follow-up. Hypertension clinic. 326 hypertensive non-diabetic subjects, 46% with metabolic syndrome (MS). Usual care treatment, which included diet, physical exercise and drugs prescribed when indicated. All patients were observed for up to 1 year. BP and low-density lipoprotein-cholesterol (LDL-C) goal were those in ESH/ESC and ATP III recommendations, respectively. The glucose goal was to delay progression to type 2 diabetes mellitus, or to achieve blood glucose <100 mg/dl for non-diabetics. According to body weight changes, patients were categorized using adjusted ROC curves models. Overall, there was a significant weight increment of 0.5 kg (95% CI 0.1-0.9 kg); 28 patients (8.6%) lost more than 5 kg, and only four (1.2%) lost more than 10 kg. BP, LDL-C and glucose goals were achieved in 56%, 78% and 61% of patients, respectively. To lose or not gain weight was an independent prognostic factor to achieve the BP goal in all the patients and the LDL goal in the presence of MS. For glucose control, being treated with beta-blockers and/or diuretics was a negative factor. In hypertensive subjects, even small changes in weight may have an important impact on achieving cardiovascular goals, mainly in those with MS.

    Abnormalities in serum lipid and lipoprotein levels are recognized major modifiable cardiovascular disease and essential hypertension risk factors. The objective of this study was to examine the serum lipid patterns of newly diagnosed hypertensive patients attending a tertiary healthcare centre in South East Nigeria. Methods. Two hundred and fifty newly diagnosed adult hypertensive patients and an equal number of age- and sex-matched controls without hypertension were consecutively recruited from the Medical and General Outpatient Clinics of Nnamdi Azikiwe University Teaching Hospital, Nnewi. Result. 126 males and 124 females were in each of the two groups. Mean age was comparable in both groups. Hypertensives had significantly higher mean systolic blood pressure, diastolic blood pressure, body mass index, waist circumference, waist-hip ratio, and fasting blood sugar than the controls. The mean TC, TG, and LDL-C were significantly higher among the hypertensives. The mean HDL-C was comparable; P = 0.8. Among the hypertensive subjects, there was statistically significant positive correlation between BMI and TC; LDL-C and TG; WC and TG; FBS and TC; LDL-C and TG. HDL-C showed a statistically significant inverse correlation with WHR in hypertensives. Conclusion. This study showed that lipid abnormalities are highly prevalent among newly diagnosed hypertensives in South-East Nigeria.

    Seven young patients with newly diagnosed severe hypertension were studied for one week. The mean age was 34.9 years (range 28-44). The mean initial values +/- s.d. for systolic and diastolic pressures were 223 +/- 27 and 141 +/- 8 mmHg, respectively. Secondary hypertension was excluded...... with ensuing fall in blood pressure was rapidly and almost completely reversible in all but one patient during conventional treatment and the increased beta 2-microglobulin excretion was totally reversible in all but one patient. Both albumin and beta 2-microglobulin excretion rate were positively correlated...... to arterial pressures in all patients. Thus glomerular and to some extent tubular protein handling were both affected in untreated patients, but rapidly reversible during initial antihypertensive treatment. The data indicate that the beta 2-microglobulin hyperexcretion is secondary to enhanced filtration...

    Full Text Available Abstract Background Non-dipping pattern in hypertensive patients has been shown to be associated with an excess of target organ damage and with an adverse outcome. The aim of our study was to assess whether a reduced nocturnal fall in blood pressure (BP, established on the basis of a single 24-h BP monitoring, in treated essential hypertensives is related to more prominent cardiac alterations. Methods We enrrolled 229 treated hypertensive patients attending the out-patient clinic of our hypertension centre; each patient was subjected to the following procedures : 1 clinic BP measurement; 2 blood and urine sampling for routine blood chemistry and urine examination; 3 standard 12-lead electrocardiogram; 4 echocardiography; 5 ambulatory BP monitoring (ABPM. For the purpose of this study ABPM was carried-out in three subgroups with different clinic BP profile : 1 patients with satisfactory BP control (BP 2 in men and 110 g/m2 in women, ≥51/gm2.7 in men and 47/g/m2.7 in women. Results Of the 229 study participants 119 (51.9% showed a fall in SBP/DBP Conclusions In treated essential hypertensives with or without BP control the extent of nocturnal BP decrease is not associated with an increase in LV mass or LVH prevalence; therefore, the non-dipping profile, diagnosed on the basis of a single ABPM, does not identify hypertensive patients with greater cardiac damage.

    Full Text Available Background: Depression and obesity are common disorders. Obesity is also predictive of several chronic diseases like hypertension and diabetes. The aim of this study was to evaluate and compare depression frequency of obese patients with hypertension or diabetes. Methods: Weight, height and body mass index (BMI were measured. The definition of obesity was a body mass index (weight (kg/height (m2 ≥30 kg/m2. Obese patients with hypertension or diabetes were documented. All participants had a Beck Depression Inventory (BDI evaluation. Results: A total of 389 subjects were included, of whom 100, 101, 92, 96 participants were healthy, obese, obese with hypertension, obese with diabetes, respectively. Beck Depression Inventory scores of obese patients, obese patients with hypertension or diabetes were higher compared to the control group. BDI scores of obese patients with diabetes were higher compared to obese and obese with hypertension subjects.

    An interaction between homocyst(e)ine and the endothelium in hypertensive patients may promote thrombogenesis and atherogenesis, leading to adverse cardiovascular events. We hypothesized that homocyst(e)ine levels are abnormal in patients with essential hypertension, and that this may be related to an adverse effect on the vascular endothelium. Accordingly, we compared plasma levels of homocyst(e)ine and von Willebrand factor (marking endothelial damage) in 83 patients (43 men; mean age 54 +/- standard deviation 15.9 years) with essential hypertension (> 160/90 mm Hg), with levels in 25 healthy normotensive controls (13 men; mean age 56+/-11.8 years). Baseline levels of the markers and other clinical indices were then related to adverse cardiovascular events at follow-up. Plasma homocyst(e)ine (P = .0001) and von Willebrand factor (P = .031) levels were significantly higher in hypertensives compared to controls. After a mean follow-up of 76 patients for 45 months (range, 1 to 66 months), 17 subjects experienced an end point of either cardiovascular death (n = 10) or adverse cardiovascular event (n = 7). Comparing these 17 with the 59 free of an end point, the former were older (P = .0002) and had a longer duration of known hypertension (P = .018). There was a nonsignificant trend toward higher median plasma homocyst(e)ine levels in the patients sustaining a vascular end point (P = .07). In this pilot study, we suggest that essential hypertension may be associated with increased plasma homocyst(e)ine levels, but that this amino acid is unrelated to endothelial damage (von Willebrand factor), clinical indices, or prognosis.

    The uptake and content of serotonin in blood platelets were studied in patients with essential hypertension and in five families in which at least one member was hypertensive. Blood was obtained from male and female normotensive volunteers and hypertensive patients who were free of medication. Lineweaver-Burk plots of 3H-serotonin uptake from both control subjects and hypertensive patients were linear, which suggested simple Michaelis-Menten uptake kinetics. The maximal uptake velocity (Vmax) in hypertensive patients was significantly lower than in control subjects (control . 41.7 +/- 3.3 pmol/min/10(8) platelets, n . 17; hypertensive . 26.6 +/- 3.0 pmol/min/10(8) platelets, n . 16; p less than 0.005). The affinity constant (Km) was slightly but significantly lower in hypertensive patients (control . 0.70 +/- 0.08 microM; hypertensive . 0.46 +/- 0.08 microM; p less than 0.05). The serotonin content in blood platelets determined by high pressure liquid chromatography with electrochemical detection was significantly lower in hypertensive patients (control . 165.0 +/- 12.9 nmol/10(11) platelets, n . 29; hypertensive . 105.9 +/- 10.4 nmol/10(11) platelets, n . 27; p less than 0.001). In the five families investigated, the lowered serotonin content was observed in some normotensive members. The reduced number of carriers of serotonin uptake and the slight decrease in the affinity constant observed in platelets of patients with essential hypertension suggest that serotonin metabolism is altered in essential hypertension and that blood platelets may be a useful model in studying the serotonergic modifications at the molecular level

    The objective was to assess the temporal impact of factors related to the development of microalbuminuria during the follow-up of young adult normoalbuminurics with high-normal blood pressure or at stage 1 of essential hypertension. Prospective follow-up was conducted on 245 normoalbuminuric hypertensive subjects (mean age 40.9 years; 134 men; blood pressure 139.7/88.6 mm Hg; body mass index 28.5 kg/m2) never treated previously with antihypertensive drugs, with yearly urinary albumin excretion measurements, until the development of microalbuminuria. After enrollment, patients were placed on usual care including nonpharmacological treatment or with an antihypertensive drug regime to achieve a blood pressure of 15 mg per 24-hour systolic blood pressure >139 mm Hg and a positive trend in fasting glucose were observed in the univariate analyses. However, in the multivariate analysis, only the baseline urinary albumin excretion and the trend of fasting glucose were independently related to the risk of developing microalbuminuria. In mild hypertensives, the development of microalbuminuria was linked to insufficient blood pressure control and to a progressive increment of glucose values.

    Background The prevalence, determinants and prognosis of pulmonary hypertension among long-term hemodialysis patients in the USA are poorly understood. Methods A cross-sectional survey of prevalence and determinants of pulmonary hypertension was performed, followed by longitudinal follow-up for all-cause mortality. Pulmonary hypertension was defined as an estimated systolic pulmonary artery pressure of >35 mmHg using echocardiograms performed within an hour after the end of dialysis. Results Prevalent in 110/288 patients (38%), the independent determinants of pulmonary hypertension were the following: left atrial diameter (odds ratio 10.1 per cm/m2, P pulmonary hypertension (53%, CMR 168.9/1000 patient-years) and 39 among 178 without pulmonary hypertension (22%, CMR 52.5/1000 patient-years) [unadjusted hazard ratio (HR) for death 2.12 (95% confidence interval 1.41–3.19), P pulmonary hypertension remained an independent predictor for all-cause mortality [HR 2.17 (95% confidence interval 1.31–3.61), P pulmonary hypertension is common and is strongly associated with an enlarged left atrium and poor long-term survival. Reducing left atrial size such as through volume control may be an attractive target to improve pulmonary hypertension. Improving pulmonary hypertension in this group of patients may improve the dismal outcomes. PMID:22290987

APA was divided into 2 types with renin-Ang II-responsive APA (n = 26) and unresponsive APA (n = 92). The plasma aldosterone concentration was lower in supine position but higher in upright position in renin-Ang II-responsive APA than in unresponsive APA patients. ARR in upright was higher in PA group (P < 0.01) but lower in PHEO group (P < 0.05) compared with EH. ARR was higher in APA than in IHA (P < 0.01).

    Leptin seems to play a role in the pathogenesis of arterial hypertension by activation of the sympathetic nervous system, influencing water - electrolyte balance and vascular remodeling. It is not known whether leptin is a factor participating in the pathogenesis of primary arterial hypertension or its higher concentration in patients with arterial hypertension reflects only the presence of other factors leading to increased blood pressure. The aim of the study was to try to estimate the leptin participation in the development of the arterial hypertension, to evaluate the concentration of leptin in blood serum of patients with mild, moderate and severe arterial hypertension and to determine the relationships between the observed leptin concentration, arterial hypertension degree according to WHO criteria and body mass. The investigations were performed on 74 untreated patients aged 19-74 years (mean 47 +/- 12 years ). In this group there were 33 women aged 35-74 years (mean 51 +/- 10 years) and 41 men aged 19-73 years (mean 45 +/- 14 years). The mild arterial hypertension was observed in 24 patients, moderate hypertension in 34 patients and severe hypertension in 16. The obesity, identified when BMI was equal or higher than 30 kg/m2, was observed in 4 patients with mild hypertension, in 9 with moderate hypertension and in 6 with severe hypertension. All patients had normal renal function. The leptin concentration was determined by the radioimmunological method using the Human Leptin RIA Kit by LINCO Research, Inc. (Cat# HL-81 K). The analysis of the obtained results was performed using Statistica for Windows PL.V5.0. The concentration of leptin in patients with mild hypertension was 3.61 +/- 2.22 ng/ml, in patients with moderate hypertension was 12.65 +/- 8.48 and in patients with severe hypertension 33.51 +/- 28.45 ng/ml. The concentration of leptin in obese patients was 24.83 +/- 26.60 and in patients without obesity was 10.57 +/- 11.99 ng/ml. 1. In patients with

    To study causes of vertigo in hypertensive patients and specify approaches to its treatment. Material and methods. Prevalence and causes of vertigo were analysed in 285 patients with arterial hypertension (AH). The examination included 24-h monitoring of arterial pressure (APM) and MR-tomography of the head. The majority of patients (78%) hospitalized with the diagnosis "hypertensive crisis" were diagnosed to have other diseases (headaches of tension, stroke, Meniere's syndrome and disease, etc.) the development of which was accompanied with hypertension and simulated a hypertensive crisis. Vertigo occurs in 20% hypertensive patients and is unrelated to elevated blood pressure. It is rather due to associated neurological, peripheral vestibular and other diseases. APM shows that vertigo occurs in hypotension after intake of hypotensive drugs. In hypertensive patients treatment of vertigo should not be directed only to management of elevated pressure but demands treatment of underlying disease. Vertigo plus mnestic disorders are effectively corrected with tanakan in a dose 120-160 mg/day. Vertigo in hypertensive patients is not caused by elevated pressure but related with concomitant neurological or peripheral vestibular diseases as well as hypotension. Hypertensive patients with vertigo need correction of the condition causing it.

    Full Text Available OBJECTIVE: to assess cardiovascular risk by means of the traditional Framingham score and the version modified through the incorporation of emerging risk factors, such as family history of acute myocardial infarction, metabolic syndrome and chronic kidney disease. METHOD: participants were 50 hypertensive patients under outpatient treatment. The clinical data were collected through a semi-structured interview and the laboratory data from patients' histories. RESULTS: it was verified that the traditional Framingham score was predominantly low (74%, with 14% showing medium risk and 12% high risk. After the inclusion of emerging risk factors, the chance of a coronary event was low in 22% of the cases, medium in 56% and high in 22%. CONCLUSIONS: the comparison between the traditional Framingham risk score and the modified version demonstrated a significant difference in the cardiovascular risk classification, whose correlation shows discreet agreement between the two scales. Lifestyle elements seem to play a determinant role in the increase in cardiovascular risk levels.

    Intradialytic hypertension with a prevalence of 15% among hemodialysis patients is with unknown pathophysiology, demographic, laboratoiy and clinical characteristic of patients, and it's influence on longtenn clinical effects (cardiovascular morbidity and mortality, rate of hospitalization). The aim of the study is to present the clinical, laboratoiy and demographic characteristics of patients with intradialytic hypertension in our dialysis center. Out of 110 hemodialysis patients, 17 patients (15,45%) had intradialytic hypertension - started at a systolic pressure greater than 140 nun Hg or had an increase in systolic pressure more than 10 mm Hg during the session, and 17 patients were nonnotensive or had a drop in blood pressure dining the dialysis. HD were performed 3 times per week with a duration of 4-5 hours, on machines with controlled ultrafiltration and high flux syntetic membrane (polyetersulfon) sterilized with gamma rays. A dialysate with standard electrolytes content was used (Na(+) 138 mmol/L, K(+) 2,0 mmol/L, Ca(++) 1,5 mmol/L, Mg (+)1,0 mmol/L, CH(3)COO(-) 3,0 mmol/L, Cl -110 mmol/1, HCO(3)(-) 35 mmol/L). We analysed the following demographic and clinical characteristics: gender, age, BMI, dialysis vintage, vascular acces, cardiovascular comorbidity (cardiomyopathy, ischemic cardiac disease, peripheral artery disease, heart valve disease), number and type of antihypertensive drugs, weekly dose of erythropoesis - stimulating agent, standard monthly, three and six months laboratoiy analyzes, and sp Kt/V and PCR. Statistical analysis was performed using the statistical software SPSS 17.0. hi both groups men were predominant (IDH group 88.23%, control group 64.07%). The IDH group was older (59.00 ± 7.64 versus 49.00 ± 13.91, p = 0.314) and with lower BMI (p = 0.246) compared to the control group. The DDH patients had significantly lower serum sodium and higher sodium gradient (135.75 ± 2.03 versus 137.33 ± 1.97, p = 0.042; 2.25 ± 1.98 versus 0.66

    Hypertension is considered a risk factor of cognitive impairments and could result in white matter changes. Current studies on hypertension-related white matter (WM) changes focus only on regional changes, and the information about global changes in WM structure network is limited. We assessed the cognitive function in 39 hypertensive patients and 37 healthy controls with a battery of neuropsychological tests. The WM structural networks were constructed by utilizing diffusion tensor tractography and calculated topological properties of the networks using a graph theoretical method. The direct and indirect correlations among cognitive impairments, brain WM network disruptions and hypertension were analyzed with structural equation modelling (SEM). Hypertensive patients showed deficits in executive function, memory and attention compared with controls. An aberrant connectivity of WM networks was found in the hypertensive patients (P Eglob = 0.005, P Lp = 0.005), especially in the frontal and parietal regions. Importantly, SEM analysis showed that the decline of executive function resulted from aberrant WM networks in hypertensive patients (p = 0.3788, CFI = 0.99). These results suggest that the cognitive decline in hypertensive patients was due to frontal and parietal WM disconnections. Our findings highlight the importance of brain protection in hypertension patients. (orig.)

    After measurement of office blood pressure (BP) and ambulatory BP monitoring (ABPM), 4 groups of patients were identified namely: (i) sustained normotensive patients (BPs are normal both clinically and by ABPM); (ii) white coat hypertensive patients (clinical BP were above limits, but ABPM were normal); (iii) masked hypertensive patients (clinical BP were normal, but ABPM were high); (iv) sustained hypertensive patients (both office and ABPM were high). The exact pathophysiologic mechanisms of these conditions are not exactly known. Besides in the literature there are only few studies that compare the 4 groups of patients together. Thus the study was carried out to compare patients with sustained normotension (SNT), white coat hypertension (WCHT), masked hypertension (MHT), and sustained hypertension (SHT). All patients underwent history taking, physical examination, laboratory analysis, and ABPM. They were referred to the cardiology department for echocardiographic evaluation. In total 85 patients with SNT, 112 patients with WCHT, 31 patients with MHT, and 81 patients with SHT were included. Going from SNT to SHT, body mass index (p<0.0001), waist circumference (p<0.0001), fasting blood glucose (p=0.002), and uric acid (p=0.029) rose progressively. Presence of metabolic syndrome was also highest in SHT and lowest in SNT (p<0.0001). Most of the metabolic risk factors were higher in patients with MHT and SHT when compared to SNT and WCHT. Studies are needed to determine whether metabolic risk factors play a causative role for the development of MHT and SHT. Copyright © 2012 Japanese College of Cardiology. Published by Elsevier Ltd.

    Full Text Available Abstract Background The low rates of hypertension treatment and control, partly due to its unawareness, are the main causes of the high stroke incidence in China. The purpose of this study was to evaluate hypertension unawareness amongst patients with first-ever stroke and to detect factors associated with its unawareness. Methods We selected those diagnosed with hypertension from patients with first-ever stroke registered in the Nanjing Stroke Registry Program between 2004 and 2014. These hypertensives were divided as being aware or unaware of their hypertension by using a brief questionnaire conducted shortly after the stroke. Multivariate logistic regression analysis was performed to identify potential factors associated with hypertension unawareness. Results Of the 5309 patients with first-ever stroke, 3732 (70.3 % were diagnosed with hypertension. Among which, 593 (15.9 % were unaware of their hypertension at the time of stroke onset. Lower-level of education (primary school or illiteracy and smoking were associated positively with hypertension unawareness; while advanced age, overweight, diabetes mellitus, heart diseases and family history of stroke were associated negatively with hypertension unawareness. Annual data analyzed indicated that the rate of hypertension awareness increased during the past 11 years (r = 0.613, P = 0.045 for trends. Conclusions A substantial proportion (15.9 % of Chinese patients with hypertension had not been aware of this covert risk until an overt stroke occurred. Hypertension unawareness was associated with lower educational levels and smoking, which address the importance of health education especially in these individuals.

  4. Pulmonary hypertension in patients with Martorell hypertensive leg ulcer: a case control study

    Science.gov (United States)

    2012-01-01

    Background Martorell hypertensive ischemic leg ulcer (Martorell ulcer) is characterized by distinct alterations in the arteriolar wall of subcutaneous vessels, leading to progressive narrowing of the vascular lumen and increase of vascular resistance. These changes are similar to the alterations observed in pulmonary arterioles in patients with chronic pulmonary hypertension (PH). This study was aimed to assess an association between the two disorders. Methods In this case–control study, 14 patients with Martorell ulcer were clinically assessed for the presence of pulmonary hypertension using transthoracic Doppler echocardiography. Data from patients were compared to 28 matched hypertensive controls. Results Systolic pulmonary arterial pressure (sPAP) in patients with Martorell ulcer was significantly higher than in the control group (33.8 ± 16.9 vs 25.3 ± 6.5 mmHg, p = 0.023); the prevalence of pulmonary hypertension was 31% (5/14) in patients and 7% (2/28) in controls (p = 0.031). No differences were seen in left heart size and function between patients and controls. Conclusion This study provides first evidence that subcutaneous arteriolosclerosis, the hallmark of Martorell ulcer, is associated with PH. These findings suggest that patients with Martorell leg ulcer might be at significant risk to develop elevated pulmonary arterial pressure. Patients with leg ulcers who present with dyspnea should be evaluated by echocardiography for the presence of pulmonary hypertension. PMID:22686459

Plasma from normotensive persons exhibits a complete lack of correlation between these factors. The consequences of the hypertension-associated COMT-inhibiting factor for the assays' specifications are discussed and data are presented for comparison with a recently-described uremia-associated COMT-inhibitor (Demassieux et al, Clin Chim Acta 115, 377-391; 1981).

    It is accepted that patient education can be beneficial in the treatment of chronic diseases. We conducted an educational intervention (EI) in hypertensive patients seen at Primary Care centres (PCC) and specialised Hypertension Units (SHU). To assess patient's knowledge of hypertension and to verify the impact of this educational initiative. A multicentre quasi-experimental study with the participation of 120 patients with hypertension. EI consisted of oral and written information which included the definition of hypertension, causes, cardiovascular risk factors and means of control. A self-administered questionnaire was used to assess patient's knowledge before and after EI. Sixty-two (52%) patients were from PCC and 58 (48%) from SHU (mean age: 61 ± 13.3 years, 59% were women). There were no differences in baseline characteristics between patients attending at PCC and SHU. The definition of hypertension (blood pressure ≥140 mmHg and/or ≥90 mmHg was known by 48% and 99% of the participants before and after EI, respectively (p hypertension was related to kidneys (54%) and eyes (58%). After EI this knowledge increased to 100% (p hypertension. However, further studies are needed to assess if EI produces behaviour changes in the long term, as this might enhance optimal blood pressure control to prevent kidney disease or delay its progression. © 2016 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Physical exercise is of paramount therapeutic importance in nonpharmacological interventions of arterial hypertension. The extent and the effects of exercise on blood pressure lowering are analyzed according to the actual literature. Suitable and nonsuitable activities are considered. Dynamic isotonic endurance training is more effective than static isometric exercise. A rather low or moderate extent of endurance training lowers the systolic and diastolic blood pressure by approximately 5-11 mmHg and 3-8 mmHg, respectively. This effect of exercise can be achieved besides the favorable effects on other cardiovascular risk factors. Intensity of exercise should be monitored by the heart rate. The mean intensity should not exceed 70% of the maximal heart rate. An initial ergometry might be suitable for the planning of training recommendations.

    The aim of the study was to assess the effect of adding spironolactone to hypertensive resistant (HTR) patients and characterize those who respond effectively. Observational retrospective study on outpatients with HTR (being treated with at least 3 drugs at full doses, one of these being a diuretic) not achieving blood pressure (BP) goals, with normal creatinine values (< 1.6 mg/dl for males and < 1.4 mg/dl in women). A total of 95 patients (70% male), average (standard deviation) age of 66 (12) years (40% diabetics), were treated with spironolactone during 4 months (range: 2-13). Mean systolic and diastolic BP fell from 170/86 (20/14) mmHg, by 29/12 mmHg (95% confidence interval [CI], 25 to 33/10 to 14 mmHg; p = 0.001). At the end of follow-up, 38% of all patients achieved the goal of BP control. Initial systolic BP < 165 mmHg (odds ratio [OR] = 3,97; 95% CI, 1.52-10.37; p = 0.005), and diabetes (OR = 0.33; 95% CI, 0.13-0.86; p = 0.02) were the only independent factors related to BP control in a logistic regression analysis. The addition of spironolactone effectively lowers BP in patients with HTR treated with 3 drugs. BP control is more difficult to achieve in diabetics.

    Full Text Available Arterial chronic hypertension (HTN is a well-known cardiovascular risk factor for development of atherosclerosis. In order to explain the relation between HTN and acute coronary syndromes the following factors should be considered: (1 risk factors are shared by the diseases, such as genetic risk, insulin resistance, sympathetic hyperactivity, and vasoactive substances (i.e., angiotensin II; (2 hypertension is associated with the development of atherosclerosis (which in turn contributes to progression of myocardial infarction. From all the registries and the data available up to now, hypertensive patients with ACS are more likely to be older, female, of nonwhite ethnicity, and having a higher prevalence of comorbidities. Data on the prognostic role of a preexisting hypertensive state in ACS patients are so far contrasting. The aim of the present paper is to focus on hypertensive patients with ACS, in order to better elucidate whether these patients are at higher risk and deserve a tailored approach for management and followup.

    Low-frequency variants showed that there is more power to detect risk variants than to detect protective variants in complex diseases. Aldosterone plays an important role in the renin-angiotensin-aldosterone system, and aldosterone synthase catalyzes the speed-controlled steps of aldosterone biosynthesis. Polymorphisms of the aldosterone synthase gene (CYP11B2) have been reported to be associated with essential hypertension (EH). CYP11B2 polymorphisms such as -344T/C, have been extensively reported, but others are less well known. This study aimed to assess the association between human CYP11B2 and EH using a haplotype-based case-control study. A total of 1024 EH patients and 956 normotensive controls, which consist of north Han population peasants, were enrolled. Seven single nucleotide polymorphisms (SNPs) (rs28659182, rs10087214, rs73715282, rs542092383, rs4543, rs28491316, and rs7463212) covering the entire human CYP11B2 gene were genotyped as markers using the MassARRAY system. The major allele G frequency of rs542092383 was found to be risk against hypertension [odds ratio (OR) 3.478, 95% confidence interval (95% CI) 1.407-8.597, P = .004]. The AG genotype frequency of SNP rs542092383 was significantly associated with an increased risk of hypertension (OR 4.513, 95% CI 1.426-14.287, P = .010). In the haplotype-based case-control analysis, the frequency of the T-G-T haplotype was higher for EH patients than for controls (OR 5.729, 95% CI 1.889-17.371, P = .000495). All |D'| values of the seven SNPs were >0.9, and r values for rs28659182- rs10087214-rs28491316-rs7463212 SNPs were >0.8 and showed strong linkage intensity. Haplotype T-G-T may therefore be a useful genetic marker for EH.

    In patients with essential hypertension under permanent propanolol treatment the muscular blood supply and the decreasing blood pressure was determined after sauna treatment using the 133 Xe muscle clearance method. Significant decrease of the blood pressure was reached already after 2 weeks sauna treatment twice a week. Continuation of sauna therapy led to permanently decreased blood pressure. The half-life period of the 133 Xe muscle clearance was significantly shortened and the functional vascular cross-section was increased. The blood pressure increased again after sauna treatment only once a week and became manifest in the prolongation of the half-life period as well as in the reduction of the functional vascular cross-section

    The appearance of the right ventricular myocardium on thallium 201 myocardial perfusion images was evaluated in patients with chronic pulmonary hypertension and compared to patients without pulmonary hypertension. Four groups of patients were studied: (1) eight normals, (2) five patients with angiographically documented coronary artery disease and normal pulmonary artery pressures, (3) ten patients with moderate to severe pulmonary parenchymal or vascular disease and documented pulmonary hypertension and (4) eight patients with chronic left ventricular dysfunction and pulmonary hypertension discovered during cardiac catheterization. The right ventricular free wall was visualized on the thallium 201 myocardial perfusion image in only one of eight normals (group 1) and in only one of the five patients with coronary artery disease (group 2) and measured 0.5 cm and 0.9 cm in thickness, respectively. In patients with documented pulmonary hypertension the right ventricle was visualized on low contrast thallium 201 myocardial perfusion image in all patients. The apparent right ventricular free wall thickness measured from the ungated thallium 201 myocardial perfusion images was 1.7 +- 0.3 cm in group 3 and 1.5 +- 0.2 cm in group 4. Right ventricular hypertrophy was detected by electrocardiography in only five of ten patients in group 3 and only one of eight patients in group 4. Thallium 201 myocardial perfusion imaging appears to be a useful technique for assessing the effects of chronic pulmonary hypertension on the right ventricular myocardium

    To prevent recurrence of cerebrovascular disease (CVD), adequate control of blood pressure (BP) is extremely important for the treatment of hypertensive CVD patients. As absence of the nocturnal fall of BP by the expected 10-20% from daytime levels is reported to exaggerate target organ injury, 24-h ambulatory blood pressure monitoring (ABPM) was conducted, especially to obtain data during nighttime sleep. Forty-eight elderly bedridden chronic phase CVD hypertensive patients (assessed 1-3 mo after CVD accident) participated. As a group, nocturnal BP was higher than diurnal BP, whereas nocturnal pulse rate was lower than diurnal pulse rate. The nocturnal BP fall was blunted in most (∼90%) of the patients. These results suggest that to perform a rational drug treatment, it is essential to do 24-h ABPM before initiation of antihypertensive therapy in elderly bedridden hypertensive CVD patients.

    Tinnitus is hearing a sound without any external acoustic stimulus. There are some clues of hypertension can cause tinnitus in different ways. The aim of the study was to evaluate the relationship between tinnitus and masked hypertension including echocardiographic parameters and severity of tinnitus. This study included 88 patients with tinnitus of at least 3 months duration and 85 age and gender-matched control subjects. Tinnitus severity index was used to classify the patients with tinnitus. After a complete medical history, all subjects underwent routine laboratory examination, office blood pressure measurement, hearing tests and ambulatory blood pressure monitoring. Masked hypertension is defined as normal office blood pressure measurement and high ambulatory blood pressure level. Baseline characteristics in patients and controls were similar. Prevalence of masked hypertension was significantly higher in patients with tinnitus than controls (18.2% vs 3.5%, p = 0.002). Office diastolic BP (76 ± 8.1 vs. 72.74 ± 8.68, p = 0.01), ambulatory 24-H diastolic BP (70.2 ± 9.6 vs. 66.9 ± 6.1, p = 0.07) and ambulatory daytime diastolic BP (73.7 ± 9.5 vs. 71.1 ± 6.2, p = 0.03) was significantly higher in patients with tinnitus than control group. Tinnitus severity index in patients without masked hypertension was 0 and tinnitus severity index in patients with masked hypertension were 2 (1-5). This study demonstrated that masked hypertension must be kept in mind if there is a complaint of tinnitus without any other obvious reason.

    Obstructive sleep apnea and hypopnea syndrome (OSAHS) is one of the developmental factors of high blood pressure (HBP), a relevant global public health problem. OSAHS is characterized by the reduction or complete cessation of respiratory airflow due to intermittent airway collapse. Additionally, significant changes in sleep rhythm and pattern are observed in these patients. To evaluate the association between OSAHS and sleep quality in essential and resistant hypertensives. A cross-sectional, observational study evaluated 43 hypertensive patients treated at the outpatient clinics of the Faculdade de Medicina do ABC (FMABC) who were medicated with two or more antihypertensive drugs and divided into nonresistant or resistant to treatment. Group I (using up to two antihypertensive agents - 60.47% of the sample) presented mean systolic blood pressure (SBP) of 127.5±6.4 mmHg, mean diastolic blood pressure (DBP) of 79.6±5.2 mmHg, mean body mass index (BMI) of 27.2±5.3 kg/m2 and mean age of 51.2±15.1 years. Group II (using more than two antihypertensive drugs - 37.2% of the sample) presented mean SBP of 132.1±9.3 mmHg, mean DBP of 84.5±5.8 mmHg, mean BMI of 27.2±7.2 kg/m2 and mean age of 55.5±13.4 years. The patients presented low quality of sleep/sleep disorder evaluated by the Pittsburgh Sleep Quality Index (PSQI), which represents a preponderant factor for OSAHS. Patients at high risk for OSAHS had poor sleep quality and high levels of DBP, suggesting a causal relation between these parameters. However, they did not present a higher prevalence of resistant high blood pressure (RHBP).

    Secondary endocrine hypertension accounts for 5-12% of hypertension's causes. In selected patients (type 2 diabetes mellitus, sleep apnea syndrome with resistant hypertension, sudden deterioration in hypertension control), prevalence could be higher. To present etiology of endocrine secondary hypertension in a series of patients younger than 40 years at hypertension's onset. Medical records of 80 patients (39M/41F), aged 30.1 ± 8.2 years (range: 12-40 years), with maximum systolic blood pressure=190.4 ± 29.2 mm Hg, range: 145-300 mm Hg, maximum diastolic blood pressure=107.7 ± 16.9 mm Hg, range: 80-170 mm Hg) referred by cardiologists for endocrine hypertension screening were retrospectively reviewed. Cardiac and renal causes of secondary hypertension were previously excluded. In all patients, plasma catecholamines were measured by ELISA and plasma cortisol by immunochemiluminescence. Orthostatic aldosterone (ELISA) and direct renin (chemiluminescence) were measured in 48 patients. Secondary endocrine hypertension was confirmed in 16 out of 80 patients (20%). Primary hyperaldosteronism was diagnosed in 7 (4M/3F) out of 48 screened patients (14.6%). i.e. 8.75% from whole group: 5 patients with adrenal tumors (3 left/2 right), 2 patients with bilateral adrenal hyperplasia; all patients were hypokalemic at diagnostic (average nadir K+ levels = 2.5 ± 0.5 mmol/L); four patients were hypokalaemic on diuretic therapy (indapamidum); other 3 patients were hypokalaemic in the absence of diuretic therapy. Cushing's syndrome was diagnosed in 6 patients (7.5%): subclinical Cushing due to 4 cm right adrenal tumour - n = 1, overt ACTH-independent Cushing's syndrome due to: macronodular adrenal hyperplasia associated with primary hyperparathyroidism - n = 1; due to adrenal carcinoma - n = 1; due to adrenal adenomas - n = 2; Cushing's disease - n = 1). Pheochromocytomas were diagnosed in 3 patients (3.75%). Primary hyperaldosteronism was the most frequent cause of secondary

    To explore the relationship between plasma endothelin and hypertension insulin resistance, and the improvement of insulin resistance in hypertension patients treated with captopril and l-amlodipine, 25 patients with primary hypertension and impaired glucose tolerance were selected and treated by captopril and l-amlodipine. Systolic pressure, diastolic pressure, fasting blood glucose, insulin and insulin antibody were measured before and after treatment and compared with healthy controls. The results showed that the plasma ET-1 level in hypertension group was significantly higher than that of healthy controls (P<0.01), and he plasma ET-1 level was positively correlated with FPG, FINS, Anti-INS, HOMA-IR. The systolic pressure, diastolic pressure, fasting blood glucose, insulin, insulin antibody and insulin resistance index in hypertension patients were decreased significantly after treatment (P<0.05). There is a good correlation between endothelin and insulin resistance index in hypertension patients. Captopril and l-amlodipine had obvious improvement effect on insulin resistance in hypertension patients. (authors)

    A recent study revealed that global overexpression of ET-1 causes a slight reduction in systemic blood pressure. Moreover, heterozygous ET-1 knockout mice are hypertensive. The role of ET-1 in human hypertension was so far not addressed by a strict meta-analysis of published human clinical studies. We included studies published between January 1, 1990 and February 28, 2017. We included case control studies analyzing untreated essential hypertension or hypertensive patients where antihypertensive medication was discontinued for at least two weeks. Based on the principle of Cochrane systematic reviews, case control studies (CCSs) in PubMed (Medline) and Google Scholar designed to identify the role of endothelin-1 (ET-1) in the pathophysiological of hypertension were screened. Review Manager Version 5.0 (Rev-Man 5.0) was applied for statistical analysis. Mean difference and 95% confidence interval (CI) were shown in inverse variance (IV) fixed-effects model or IV random-effects models. Eleven studies fulfilling our in- and exclusion criteria were eligible for this meta-analysis. These studies included 450 hypertensive patients and 328 controls. Our meta-analysis revealed that ET-1 plasma concentrations were higher in hypertensive patients as compared to the control patients [mean difference between groups 1.57 pg/mL, 95%CI [0.47∼2.68, P = 0.005]. These finding were driven by patients having systolic blood pressure higher than 160 mmHg and diastolic blood pressure higher than 100 mmHg. This meta-analysis showed that hypertensive patients do have elevated plasma ET-1 concentrations. This finding is driven by those patients with high systolic/diastolic blood pressure. Given that the ET-1 gene did not appear in any of the whole genome association studies searching for hypertension associated gene loci, it is very likely that the elevated plasma ET-1 concentrations in hypertensive patients are secondary to hypertension and may reflect endothelial cell damage. © 2017 The

    The present research investigated the effects of two different types of music on cardiovascular responses in essential hypertensive men in comparison with healthy men based on introversion and extraversion. One hundred and thirteen hypertensive men referred to Madani Heart Hospital in Tabriz completed the NEO-FFI Questionnaire and after obtaining acceptable scores were classified in four groups: introvert patients, extravert patients, introvert healthy subjects, and extravert healthy subjects (each group with 25 samples with age range 31-50). Baseline blood pressure and heart rate of each subject was recorded without any stimulus. Then subjects were exposed to slow-beat music and blood pressure and heart rate were recorded. After15 minute break, and a little cognitive task for distraction, subjects were exposed to fast-beat music and blood pressure and heart rate were recorded again. Multivariate analysis of covariance (MANCOVA) test showed that extravert patient subjects obtained greater reduction in systolic blood pressure and heart rate after presenting slow-beat music compared with introvert patients (P= 0.035, and P= 0.033 respectively). And extravert healthy subjects obtained greater reduction in heart rate after presenting slow-beat music compared with introvert healthy subjects (P= 0.036). However, there are no significant differences between introvert and extravert groups in systolic and diastolic blood pressure and heart rate after presenting fast-beat music. Based on our results, introvert subjects experience negative emotions more than extravert subjects and negative emotions cause less change in blood pressure in these subjects compared with extravert subjects.

    Full Text Available Abstract Background The renin-angiotensin aldosterone system (RAAS plays an important role in regulating the blood pressure and the genetic polymorphisms of RAAS genes has been extensively studied in relation to the cardiovascular diseases in various populations with conflicting results. The aim of this study was to determine the association of five genetic polymorphisms (A6G and A20C of angiotensinogen (AGT, MboI of renin, Gly460Trp of aldosterone synthase and Lys173Arg of adducin of RAAS genes in Malaysian essential hypertensive and type 2 diabetic subjects. Methods RAAS gene polymorphisms were determined using mutagenically separated PCR and PCR-RFLP method in a total of 270 subjects consisting of 70 hypertensive subjects without type 2 diabetes mellitus (T2DM, 60 T2DM, 65 hypertensive subjects with T2DM and 75 control subjects. Results There was significant difference found in age, body mass index, systolic/diastolic blood pressure, fasting plasma glucose and high density lipoprotein cholesterol levels between the hypertensive subjects with or without T2DM and control subjects. No statistically significant differences between groups were found in the allele frequency and genotype distribution for A20C variant of AGT gene, MboI of renin, Gly460Trp of aldosterone and Lys173Arg of adducin (p > 0.05. However, the results for A6G of AGT gene revealed significant differences in allele and genotype frequencies in essential hypertension with or without T2DM (p Conclusion Among the five polymorphisms of RAAS genes only A6G variant of AGT gene was significantly associated in Malaysian essential hypertensive and type 2 diabetic subjects. Therefore, A6G polymorphism of the AGT gene could be a potential genetic marker for increased susceptibility to essential hypertension with or without T2DMin Malaysian subjects.

    Lifestyle, habits, diet, and genetics are all important factors associated with the prevalence of hypertension. Many association studies have been performed in the Chinese Han population, whereas data explaining the high prevalence of hypertension in the Mongolian population remain scarce. In the present study, we aimed to determine the factors associated with the development of essential hypertension in Mongolians. A total of 194 hypertensive cases and 201 controls from Dongwu County were enrolled in the study. Demographics, anthropometric and blood biochemical parameters, food intake, lifestyle, habits, education, occupation, and family history were recorded for each subject. Genotype and allele frequencies of six single nucleotide polymorphisms (SNPs) of the kallikrein 1 (KLK1) gene were also examined. Mean body mass index, waistline, hipline, blood sugar, blood urea nitrogen, creatinine, uric acid, total cholesterol, triglyceride, and low-density lipoprotein levels were all significantly higher in the hypertensive group (Pcontrols (Pcontrol groups (P>0.05). These results suggest that dietary history and habits have the most important influence on the development of essential hypertension in the Mongolian population.

    To characterize the effects of regular Roselle ingestion on blood pressure and left ventricular hypertrophy (LVH) in patients with established moderate essential hypertension. This non-randomized quasi-experimental study was conducted in Kafr El-Shaikh, Egypt, for 8 weeks, from September 2012 to November 2012. The effects of a 4-week period of regular Roselle ingestion followed by a 4-week recovery period on systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), and heart rates (HR) was studied in 2 equal, gender- and age-matched groups (n=50 each; average age - 50+/-5 years) of normotensive subjects, and patients with moderate essential hypertension. Electrocardiographic assessments of LVH were also made prior to, and at the end of both treatment and recovery periods. Pulse pressure (PP) significantly fell from baseline values by 10.9% (normotensive group [NG]), 21.2% (hypertensive group [HG]); SBP by 10% (NG), 19.6% (HG); DBP by 9.5% (NG), 18.7% (HG), and HR by 14.6% (NG), 17.1% (HG) by the end of week 4 of treatment. Following treatment cessation, SBP, DBP, PP, and HR returned to pretreatment levels over 4 weeks. Before intervention, none of the normotensive subjects, but 14 hypertensive patients showed LVH. However, Roselle treatment was associated with regression of LVH in 10 patients with only 4 patients showing LVH after 4 weeks of treatment. This became 10 patients 4 weeks after ceasing treatment. These findings empirically suggest favorable cardiovascular effects of Roselle in patients with established moderate essential hypertension.

    Attenuation of the effectiveness of antihypertensive therapy by non-steroidal anti-inflammatory (NSAI) drugs has been attributed to inhibition of systemic or renal vasodilator prostaglandin synthesis, or a combination of both. Indomethacin is a NSAI drug with both renal and extrarenal cyclo-oxygenase inhibition properties. Sulindac is a relatively selective cyclo-oxygenase inhibitor said not to affect urinary prostaglandin excretion. This study examines the relative effect on blood pressure of 4 weeks' treatment, with indomethacin 25 mg three times daily and sulindac 200 mg twice daily, in a randomized placebo controlled trial in 26 hypertensive subjects. In nine patients treated with indomethacin, supine blood pressure rose 11 mmHg systolic and 4 mmHg diastolic by the end of the first week, whereas nine subjects treated with sulindac showed a fall in blood pressure similar to the trend seen in placebo-treated subjects. Indomethacin treatment inhibited renal cyclo-oxygenase with a 78% reduction in urinary prostaglandin E2 excretion and 89% suppression of plasma renin activity. Neither measurement was affected by sulindac. Extrarenal cyclo-oxygenase activity was inhibited by both indomethacin and sulindac with serum thromboxane B2 decreasing by 96% and 69% respectively. The results suggest that the pressor effect of NSAI drugs is predominantly related to renal cyclo-oxygenase inhibition. the lack of effect of sulindac on blood pressure may make it a safer therapeutic option if NSAI drug therapy is necessary in the hypertensive patient.

    To study associations of C825T (rs5443) and G272S (rs16932941) polymorphisms of GNB3 gene in Russian population of the Central Chernozem region with essential hypertension (EH) risk; to elicit the role of environmental risk factors in realization of EH predisposition in this gene genotypes carriers. We studied DNA samples obtained from 205 EH patients and 207 healthy individuals. EH patients were treated in Kursk hospitals. Genotyping of GNB3 gene polymorphisms was conducted by polymerase chain reaction and restriction analysis. Prevalence of 82ST allele of GNB3 gene in EH patients and healthy individual was 0.334 and 0.295, respectively, of 272S allele--0.037 and 0.058, respectively. We found no significant differences by prevalence of genotypes of gene GNB3 polymorphisms C825T and G272S in EH patients and healthy individuals. Non-smoking carriers of 272GS genotype had a low risk of EH (OR 0.42 in 95% CI from 0.18 to 0.97; p = 0.04). Smokers had no protective effect of this genotype. The protective effect of 272GS genotype was also found in individuals with low or moderate alcohol drinking habits (OR 0.29 in 95% CI from 0.11 to 0.77, p = 0.02) and in individuals without chronic exposure to stress (OR 0.29 in 95% CI from 0.09 to 0.91, p = 0.04). In contrast, hard drinkers and patients exposed to chronic stress had no protective effect of heterozygous genotype 272GS of gene GNB3. G272S polymorphism of GNB3 gene can be considered as a new genetic marker of predisposition to EH. The protective effect depends of environmental factors associated with high risk to develop EH.

    Full Text Available Ramadan is a holy month for Muslims and fasting in this month is the rule for any healthy matured person. Nutritional and behavioral changes occurred during Ramadan fasting may lead to several physiological change, such as blood pressure (2. Studies evaluated the effects of Ramadan fasting on blood pressure in hypertensive patients, are scarce and reported inadequate results. In this paper a systematic review was performed to accumulate the results of published literature designed to evaluate blood pressure changes in hypertensive patients due to Ramadan fasting. All prospective, English studies which evaluated the effects of Ramadan fasting on blood pressure in hypertensive patients and measured systolic and diastolic blood pressure twice at least ( before Ramadan and during last week of Ramadan or after Ramadan fasting were included in systematic review . Five studies reported the effect of Ramadan fasting on blood pressure in hypertensive patients in full text. Although significant reduction in systolic blood pressure during Ramadan fasting were seen in 3 studies (3-5, other 3 studies reported no significant difference between systolic blood pressure before and after Ramadan fasting (6, 7. Among 6 studies that reviewed in this paper, 4 studies reported no significant changes in diastolic blood pressure (4, 6, 7. While 2 other studies reported significant reduction in systolic blood pressure after Ramadan fasting (3, 5. This systematic review suggested that Ramadan fasting can be safe in treated essential hypertensive patients with continuation of previous medications. Also it can improve systolic and diastolic blood pressures.

    AIM: To determine the age-specific prevalence of breast arterial calcifications in patients with systemic hypertension. METHODS: The mammograms and patient records of 2406 women who underwent screening or diagnostic mammography were reviewed retrospectively. Mammograms were evaluated for the presence of arterial calcification and results were coded. Hypertension was defined as use of anti-hypertensive agents and diabetes was defined as use of oral hypoglycaemic agents or insulin. RESULTS: The prevalence of breast arterial calcification among hypertensives (17.6%) was lower than among diabetics (25.4%). The prevalence in the non-diabetic, non-hypertensive group was lowest (7.3%). The prevalence increased with age in all three groups. The highest prevalence was found in diabetics older than 60 years (81.8%). Breast arterial calcification was not found among women younger than 40 years. CONCLUSION: Breast arterial calcification is associated with hypertension and prevalence increases with age. Breast arterial calcification on mammograms may indicate unsuspected hypertension especially in non-diabetic patients

    To determine the serum and intraerythrocyte concentrations of vasoactive ions in patients of diabetes mellitus of either gender with hypertension. The study was conducted on 48 volunteers. Out of 48, 24(12 men and 12 women) were hypertensive patients with diabetes mellitus. Remaining (12 men and 12 women) were normal healthy subjects. Biochemical estimations were done by flame photometry and spectrophotometry. Data were analyzed by Two-way ANOVA followed by Newman-Keuls test. A decrease in serum concentrations of sodium, calcium, magnesium, phosphorus, chloride and intraerythrocyte potassium and an increase in the levels of glucose, haematocrit and intraerythrocyte sodium was observed in both male and female patients with diabetes mellitus and hypertension. No significant changes were observed in serum potassium levels. The results suggest that dysregulations of electrolyte balance caused by hyperinsulinemia or altered glucose metabolism may lead to hypertension. (author)

    Since the control rate of blood pressure is lower in mainland China, the aim of this study is to investigate the proportion of secondary causes and coexisting diseases of hypertension in hypertensive patients. Data on consecutive patients with hypertension who visited the Hypertension Center. Diseases were detected using an established strict screening protocol. Detection rate of secondary causes and coexisting diseases of hypertension was 39.5% among 3003 hypertensive patients. Obstructive sleep apnea (OSA) was the most common, accounting for 24.7% of patients, followed by primary aldosteronism (PA) (5.8%) and PA + OSA (4.9%). Endocrine hypertension accounted for 12.1% of patients, including 10.7% of patients with PA, 1.1% with hypothyroidism, 0.1% with pheochromocytoma, 0.1% with Cushing's syndrome, and 0.1% with hyperthyroidism, respectively. Those who smoke, those who are obese, and those who have diabetes accounted for 31.3%, 27.5%, and 16.6% of total patients, respectively. There were overlapping conditions in secondary causes and coexisting diseases of hypertension. OSA was the most common in each age- and BMI-stratified group. Findings from the current study suggest an increasing frequency of secondary forms of hypertension, highlighting the burden of OSA and PA in hypertensive patients.

    The effectiveness of exercise-treadmill testing in diagnosing coronary-artery disease in hypertensive patients is limited by a high rate of false positivity. Exercise radionuclide ventriculography, however, relies on different criteria (ejection fraction and wall motion), and we have evaluated this procedure in 37 hypertensive and 109 normotensive patients with chest pain, using coronary arteriography as an indicator of coronary disease. In the hypertensive cohort there was no difference in the ejection fraction at rest between the 17 patients with coronary disease and the 20 without it. Neither group had a significant mean (+/- S.E.M.) change in ejection fraction from rest to exercise (-1.9 +/- 2 and 1.4 +/- 1%, respectively). A wall-motion abnormality developed during exercise in 5 of the 17 hypertensive patients with coronary disease (29%) and in 4 of the 20 without it (20%) (P = not significant). In the normotensive cohort, however, the peak-exercise ejection fractions were significantly different. The 71 patients with coronary disease had a mean decrease of 3.6 +/- 1%, in contrast to the patients without coronary disease, who had an increase of +/- 1% (P < 0.001). An exercise-induced wall-motion abnormality was seen in 35 of the 71 patients with coronary disease (48%), as compared with 3 of the 38 without it (8%) (P < 0.001). We conclude that exercise radionuclide ventriculography is inadequate as a screening test for coronary atherosclerosis in hypertensive patients with chest pain. 28 references, 2 figures, 3 tables

    BACKGROUND: Existing data on gastric emptying and small-intestinal transit rates in portal-hypertensive patients are scarce and contradictory, and so far, the motor function of the colon has not been assessed in these patients. In this study we evaluated the propulsive effect of all main segments...... of the gastrointestinal tract in patients with well-characterized portal hypertension. METHODS: Eight patients with a postsinusoidal hepatic pressure gradient of at least 13 mmHg and eight age- and sex-matched healthy controls participated in the study. Gastric emptying, small-intestinal transit, and colonic transit...... the test meal between patients and controls. CONCLUSIONS: These data suggest that the colonic transit is often accelerated in patients with portal hypertension, whereas the motor function of the stomach and the small intestine is unaffected....

  10. Special management needs of the elderly hypertensive patient

    Full Text Available Cardiovascular (CV disease will progressively assume greater importance as the number of elderly individuals in the population of the world increases with a parallel increase in the incidence of hypertension. Elderly patients with hypertension are often difficult to manage. Pathophysiological changes associated with ageing are also associated with long-standing, uncontrolled hypertension. Diagnosis may not be straightforward and the incidence of concomitant disease will be higher than in younger patients. The preventative benefits of antihypertensive therapy in the elderly is well established and treatment of hypertension is of greatest value in older patients who, because of additional risk factors or prevalent CV disease, are at a higher risk of developing a CV event. However, established benefits are based upon the evidence from randomised, controlled trials in selected patient groups, which may not be universally applicable to many elderly hypertensives. Thus, the treatment of hypertension in the elderly should be based upon an individualised approach which inevitably cannot be strictly evidence-based. However, there is a compelling case for an approach based upon a recognition that high blood pressure (BP in the elderly should be treated early and vigorously whilst at the same time exercising some caution to avoid the development of hypotensive BP levels.

    Hypertension is more prevalent in the elderly (age>65 years) diabetic population than in the general population and shows an increasing prevalence with advancing age. Both diabetes mellitus (DM) and hypertension are independent risk factors for cardiovascular (CV) related morbidity and mortality. Optimal BP targets were not identified in elderly patients with DM and hypertension. Areas covered: In this review article, the authors briefly discuss the pathophysiology of hypertension in elderly diabetics, present evidence with various antihypertensive drug classes supporting the treatment of hypertension to reduce CV events in older diabetics, and then discuss the optimal target BP goals in these patients. Expert opinion: Clinicians should have a BP goal of less than 130/80 mm in all elderly patients with hypertension and DM, especially in those with high CV-risk. When medications are required for optimal BP control in addition to lifestyle measures, either thiazide diuretics, angiotensin-converting-enzyme inhibitors, angiotensin receptor blockers, or calcium channel blockers should be considered as initial therapy. Combinations of medications are usually required in these patients because BP control is more difficult to achieve in diabetics than those without DM.

    Pulmonary hypertension is a disease of poor prognosis when is associated with pregnancy. A maternal mortality of 30-56% and a neonatal survival of approximately 85% is reported. Surveillance of patients with severe pulmonary hypertension during pregnancy must be multidisciplinary, to provide information and optimal treatment during and after gestation. Targeted therapy for pulmonary arterial hypertension during pregnancy significantly reduces mortality. The critical period with respect to mortality, is the first month after birth. Propose an algorithm for management during pregnancy for patients with severe pulmonary hypertension who want to continue with it. The recommendations established with clinical evidence for patients with severe pulmonary hypertension and pregnancy are presented: diagnosis, treatment, obstetrics and cardiology management, preoperative recommendations for termination of pregnancy, post-partum care and contraception. The maternal mortality remains significantly higher in patients with severe pulmonary hypertension and pregnancy, in these cases should be performed multidisciplinary management in hospitals that have experience in the management of this disease and its complications.

    Full Text Available Background/Aim. Beside arterial hypertension as the most important factor of a myocardial hypertension development, very important risk factors are obesity, hypercholesterolemia, insulin resistance, etc. The aim of the study was to examine the influence of metabolic syndrome (MetS on left ventricular hypertrophy in patients with arterial hypertension. Methods. We checked medical records for 138 patients with arterial hypertension, and compared them with the control group of 44 normotensive subjects. The patients with arterial hypertension were divided into two groups considering the presence of MetS: with MetS (59 patients, and without MetS (79 patients. We defined MetS as presence of three (or more within five criteria: central obesity (> 102 cm male, > 88 cm female, raised triglycerides (> 1.7 mmol/L, or drug treatment for elevated triglycerides, reduced high density lipoprotein (HDL cholesterol (< 1.03 mmol/L male, < 1.3 mmol/L female, raised blood pressure (> 130 mmHg systolic, > 90 mmHg diastolic, raised fasting glucose (> 6.11 mmol/L, or drug treatment for elevated glucose level. In each group routine laboratory, echocardiography and 24-hour ambulatory blood pressure monitoring were performed. Results. We found statisticaly significant higher left ventricular mass in both subgroups hypertensive patients in comparison with the control group (p < 0.05. We did not find statistically significant difference (227.31±63.44 vs 219±59.5, p > 0.05 in left ventricular mass between these two groups of patients. In the patients with arterial hypertension and MetS we found hypertrophy more frequently than in the subgroup without MetS (43/57 vs 34/69, p < 0.001. Conclusion. Our results suggest that associated cardiometabolic risks increase the prevalence of myocardial hypertrophy, but do not influence left ventricular mass.

    Full Text Available We evaluate in this study the factors associated with the effect of age on blood pressure in more than 4800 patients. Their physicians referred them to evaluate for secondary causes for their hypertension. Factors studied included history and physical examination, serum sodium, potassium and creatinine, a stimulated plasma renin and catecholamine. We also studied the blood pressure response to infusion of either saralasin (an angiotensin II analogue or enalapril (an angiotensin converting enzyme inhibitor, and plasma aldosterone and cortisol after infusion of saline. We measured serum thyroxin and thyroid stimulating hormone concentrations on 1061 consecutive patients in this series. The results of our study show that increased age is associated with a significant increase in the prevalence of hypertension and especially of systolic hypertension after age 60 years. Increased obesity between age 30-50 years is associated with significant increases in diastolic blood pressure and this trend is also seen in African-Americans who are heavier than whites. Increased age is associated with an increased prevalence of secondary forms of hypertension including atherosclerotic renovascular hypertension, renal insufficiency and primary hypothyroidism.

    Full Text Available OBJECTIVE: A double-blind, placebo-controlled multicenter study involving 34 centers from different Brazilian regions was performed to evaluate the antihypertensive efficacy and tolerability of trandolapril, an angiotensin I converting enzyme inhibitor, in the treatment of mild-to-moderate systemic arterial hypertension. METHODS: Of 262 patients enrolled in this study, 127 were treated with trandolapril 2 mg/day for 8 consecutive weeks, and the remaining 135 patients received placebo for the same period of time. Reduction in blood pressure (BP and the occurrence of adverse events during this period were evaluated in both groups. RESULTS: Significant reductions in both systolic and diastolic pressures were observed in patients treated with trandolapril when compared with those on placebo. Antihypertensive efficacy was achieved in 57.5% of the patients on trandolapril and in 42% of these normal values of BP were obtained. The efficacy of trandolapril was similar in all centers, regardless of the area of the country. In a subset of 30 patients who underwent ABPM, responders showed a significant hypotensive effect to trandolapril throughout the 24 hour day. The adverse event profile was similar in both trandolapril and placebo groups. CONCLUSION: Our results demonstrate, for the first time in a large group of hypertensive patients from different regions in Brazil, good efficacy and tolerability of trandolapril during treatment of mild-to-moderate essential systemic hypertension.

    Racial variations are reported in the natural history of hypertension. For example, hypertension is significantly more prevalent in blacks than whites. Endothelial cells are important regulators of vascular tone and homeostasis, in part through secretions of vasoactive substances including endothelin-1 (ET-1), a small peptide with potent vasopressor actions. In black hypertensives, ET-1 levels are higher than in normotensive blacks and in both hypertensive and normotensive whites. Since ET-1 might play a significant role in the development and severity of hypertension in the indigenous Arab population of the United Arab Emirates, we investigated the circulating levels of ET-1 in this homogenous population. ET-1 levels were measured in plasma samples from 60 untreated hypertensive Arabs and compared with 60 age- and sex-matched normotensive controls. ET-1 levels were significantly higher in hypertensives (mean 10.1 +/- 1 pmol/L) than normotensives (mean 2.2 +/- 0.5 pmol/L). Body mass index (BMI) was slightly higher among the hypertensives. For all subjects these levels significantly (P Arabs as compared with reported levels in white hypertensives and ET-1 could be a risk factor for cardiovascular diseases in this population. The endothelial system might be particularly important with respect to hypertension in this racial group and merits further study.

    Full Text Available Abstract Background Despite the availability of a wide selection of effective antihypertensive treatments and the existence of clear treatment guidelines, many patients with hypertension do not have controlled blood pressure. We conducted a qualitative study to explore beliefs and perceptions regarding hypertension and gain an understanding of barriers to treatment among patients with and without diabetes. Methods Ten focus groups were held for patients with hypertension in three age ranges, with and without diabetes. The topic guides for the groups were: What will determine your future health status? What do you understand by "raised blood pressure"? How should one go about treating raised blood pressure? Results People with hypertension tend to see hypertension not as a disease but as a risk factor for myocardial infarction or stroke. They do not view it as a continuous, degenerative process of damage to the vascular system, but rather as a binary risk process, within which you can either be a winner (not become ill or a loser. This makes non-adherence to treatment a gamble with a potential positive outcome. Patients with diabetes are more likely to accept hypertension as a chronic illness with minor impact on their routine, and less important than their diabetes. Most participants overestimated the effect of stress as a causative factor believing that a reduction in levels of stress is the most important treatment modality. Many believe they "know their bodies" and are able to control their blood pressure. Patients without diabetes were most likely to adopt a treatment which is a compromise between their physician's suggestions and their own understanding of hypertension. Conclusion Patient denial and non-adherence to hypertension treatment is a prevalent phenomenon reflecting a conscious choice made by the patient, based on his knowledge and perceptions regarding the medical condition and its treatment.

    There is strong correlation among hypertension, obesity, hyperlipidemia and hyperuricemia which are important risk factor for the cardiovascular disease. Objective of this study was to assess and compare the prevalence of obesity, hyperlipidemia and hyperuricemia among young and old hypertensive patients in the local setting. This cross-sectional study was conducted at medical Out-patient Department at Shahina Jamil Teaching Hospital, Abbottabad, from September 2007 to February 2008. Eighty-six patients seen in the medical outpatient department were enrolled in the study. Patients with age 15 years or above and diagnosed as case of systemic hypertension were included. Patients with endocrine disease, pregnancy, coarctation of aorta, and renal disease leading to hypertension were excluded from the study. Total eighty-six patients with mean age of 53.7+- 12.9 years were included in the study. Patients were divided into younger age group (age <46 years) and older age group (age greater or equal to 46 years). Mean Body Mass Index (BMI) was 29.7 +- 5.2 in the younger age group and 26.9 +- 4.7 in the older age group, mean serum cholesterol level was 192.2 +- 14.2 mg/dL in younger age group and 190.9 +- 18.3 mg/dL in the older age group, mean serum triglyceride level was 170.5 +- 13.7 mg/dL in younger age group and 166.6 +-21.4 mg/dL in the older age group and mean serum uric acid levels were 5.6 +- 0.7 mg/dL in younger age group and 5.7 +- 1.2 mg/dL in the older age group. Overweight and obese patients were 70.9% with its higher prevalence in younger (86.2%) as compared to older patients (63.2%). Hypercholesterolemia was found in 27.9% of the patients, with a frequency of 24.1% in younger patients and 29.8% in the older patients. Hypertriglyceridemia was seen in 66.3% of the patients, with a frequency of 69.0% in younger patients and 64.9% in the older patients.

    Full Text Available Hypertension is a common health problems that can increase the mortality and mobility rate in the community. As a silent killer, the prevalence of this disease is increasing worldwide. The prevalence of hypertension in Indonesia is 25.8% and West Java is ranked at top four with prevalence of 29.4%. This study aimed to measure the level of knowledge of hypertensive patients about their disease. This study was an observational study using cross-sectional design in June–October 2017 at Apotek Pendidikan Universitas Padjadjaran, Bandung City. A total of one hundred and fifty respondents completed a validated questionnaire after signing informed consent. The results showed that 56.7% of respondents have “good” level of knowledge, 40% of respondents have “moderate” level of knowledge, and 3.3% of respondents have “poor” level of knowledge. Data were analyzed statistically, the results showed that there was no significant difference (p>0.05 between each group of respondents to sociodemographic and clinical characteristics of the patients. Only fifty percent of respondents have “good” level of knowledge, patients who have “moderate” and “poor” level of knowledge generally are patients with low levels of education and suffer from hypertension less than five years.

Aim of the study was to investigate in a large cohort of hypertensive patients the prevalence of RHT, and to identify in these patients the secondary forms of arterial hypertension (SH. We enrolled a series of 3685 consecutive hypertensive patients. All patients underwent complete physical examination, laboratory tests, screening for SH. Ambulatory blood pressure monitoring (ABPM was performed to exclude white-coat hypertension. Further, we investigated for any obstructive sleep apnea syndrome (OSA. Only 232 (5.8% hypertensive patients fulfilled criteria for RHT. 91 (39% had a SH; 56 (61% hypertensive patients had a primary aldosteronism, 22 (24% had OSA, 7 (7.7% had a hypercortisolism, and 5 (5.5% had a renovascular hypertension (RVH. Only one patient had adrenal pheochromocytoma. An accurate definition and investigation into RHT is needed. We recommend ABPM to all patients at diagnosis. Finally, all patients must be screened for SH, such as adrenal hypertension, OSA and RVH, especially those who are apparently resistant to polypharmacological treatment.

    Essential hypertension (EH) is a complex disease in which physiological, environmental, and genetic factors are involved in its genesis. The genetic variant of the alpha-adducin gene (ADD1) has been described as a risk factor for EH, but with controversial results.The objective of this study was to evaluate the association of ADD1 (Gly460Trp) gene polymorphism with the EH risk in a population from Madeira Island.A case-control study with 1614 individuals of Caucasian origin was performed, including 817 individuals with EH and 797 controls. Cases and controls were matched for sex and age, by frequency-matching method. All participants collected blood for biochemical and genotypic analysis for the Gly460Trp polymorphism. We further investigated which variables were independently associated to EH, and, consequently, analyzed their interactions.In our study, we found a significant association between the ADD1 gene polymorphism and EH (odds ratio 2.484, P = .01). This association remained statistically significant after the multivariate analysis (odds ratio 2.548, P = .02).The ADD1 Gly460Trp gene polymorphism is significantly and independently associated with EH risk in our population. The knowledge of genetic polymorphisms associated with EH is of paramount importance because it leads to a better understanding of the etiology and pathophysiology of this pathology.

    Masked hypertension is associated with an increased risk for cardiovascular conditions. The aim of the study was to evaluate the relationship obesity parameters, including body weight, waist circumference, and body mass index. The study group consisted of 251 consecutive outpatient subjects without overt hypertension. Subjects were classified according to BMI. After a complete medical history and laboratory examination, patients' height, weight, waist circumference heart rate, and office blood pressure were recorded. All subjects underwent ambulatory blood pressure monitoring. Masked hypertension is defined as normal office blood pressure measurement and high ambulatory blood pressure level. Baseline characteristics in patients and controls were similar. Prevalence of Masked hypertension was significantly higher in patients with obesity than controls (30.9% vs 5.7%, p < 0.001). Body mass index (33.2 ± 4.3 vs 25.1 ± 2.7 p < 0.001), waist circumference (98.5 ± 11.7 vs 86.8 ± 8.8, p < 0.001), and weight (86.5 ± 11.8 vs. 69 ± 9.1, p < 0.001) in patients with obesity were significantly higher than in patients with normal weight. Office Systolic BP (121.8 ± 4.4 vs 120.5 ± 4.78, p = 0.035), ambulatory daytime systolic BP (128.8 ± 8.9 vs 124.5 ± 7.4, p < 0.001), ambulatory daytime diastolic BP (73.9 ± 9.5 vs 71.5 ± 7.0, p = 0.019), ambulatory night-time systolic BP in patients with obesity was significantly higher than in patients with normal weight. This study demonstrated that masked hypertension prevalence is higher in patients with obesity than control patients. It can be suggested that predefining obesity might be helpful in early detection of masked hypertension.

    PurposeTo classify the renal artery (RA) anatomy based on specific requirements for endovascular renal artery denervation (RDN) in patients with drug-resistant hypertension (RH).Materials and MethodsThe RA anatomy of 122 consecutive RH patients was evaluated by computed tomography angiography and classified as two types: A (main RA ≥20 mm in length and ≥4.0 mm in diameter) or B (main RA <20 mm in length or main RA <4.0 mm in diameter). The A type included three subtypes: A1 (without accessory RAs), A2 (with accessory RAs <3.0 mm in diameter), and A3 (with accessory RAs ≥3.0 mm in diameter]. A1 and A2 types were eligible for RDN with the Simplicity Flex catheter. Type B included twi subtypes based on the main RA length and diameter. Patients were accordingly classified into three eligibility categories: complete (CE; both RAs were eligible), partial (PE; one eligible RA), and noneligibility (NE; no eligible RA).ResultsBilateral A1 type was the most prevalent and was observed in 48.4 % of the patients followed by the A1/A2 type (18 %). CE, PE, and NE were observed in 69.7, 22.9, and 7.4 % of patients, respectively. The prevalence of accessory RAs was 41 %.ConclusionsOf RH patients, 30.3 % were not eligible for bilateral RDN with the current Simplicity Flex catheter. This classification provides the basis for standardized reporting to allow for pooling of results of larger patient cohorts in the future

    The cause of hyperalbuminuria in hypertonic patients can be functional or irreversible structural changes. The objective of the present investigation was an attempt to differentiate these two possibilities by comparing data of hypertonic patients with normal albuminuria (albumin excretion value for microalbuminuria. The results suggest that microalbuminuria in hypertensive patients is as a rule a manifestation of structural renal changes, while also functional and reversible changes participate. The asset of treatment of hypertension by angioplasty of the renal arteries was manifested not only in the renal haemodynamics but also by reduced albuminuria.

  13. Morning pressor surge, blood pressure variability, and arterial stiffness in essential hypertension.

    2017-02-01

    An excess morning blood pressure surge (MBPS) may portend an increased cardiovascular risk, but the mechanisms thereof have been little investigated. The link between MBPS, short-term blood pressure (BP) variability, and arterial stiffness has not been entirely defined. In 602 consecutive untreated hypertensive patients (48 ± 12 years, 61% men, office BP 149/93 ± 17/10 mmHg), we measured carotid-femoral pulse wave velocity (cf-PWV, SphygmoCor) and 24-h ambulatory BP. Using self-reported sleep and wake times, MBPS was defined as sleep-trough (ST-MBPS), prewaking, rising. Short-term BP variability was calculated as weighted 24-h SBP SD and average real variability of 24-h SBP (ARV), that is, average of absolute differences between consecutive SBP readings. ST-MBPS (r = 0.16, P < 0.001) and rising MBPS (r = 0.12, P = 0.003) showed a direct correlation with cf-PWV, whereas prewaking MBPS had no such relation (r = 0.06, P = 0.14). Only ST-MBPS was independently associated with cf-PWV (t = 1.96, P = 0.04) after adjustment for age, sex, height, office mean arterial pressure, heart rate, and renal function. This association was lost after further adjustment for weighted 24-h SBP SD (P = 0.13) or ARV (P = 0.24). ARV was a significant mediator of the relationship between ST-MBPS and cf-PWV (P = 0.003). In untreated hypertension, ST-MBPS has a direct relation with aortic stiffness, which is mediated by an increased ARV. The adverse effects of MBPS may be partly explained by its link with arterial stiffness, mediated by short-term SBP variability.

    Full Text Available Nilay Kumar,1 David A Calhoun,2 Tanja Dudenbostel21Department of Medicine, 2Division of Cardiovascular Disease, Hypertension and Vascular Biology Program, University of Alabama at Birmingham, Birmingham, AL, USAAbstract: Resistant hypertension (RHTN is an increasingly common clinical problem that is often heterogeneous in etiology, risk factors, and comorbidities. It is defined as uncontrolled blood pressure on optimal doses of three antihypertensive agents, ideally one being a diuretic. The definition also includes controlled hypertension with use of four or more antihypertensive agents. Recent observational studies have advanced the characterization of patients with RHTN. Patients with RHTN have higher rates of cardiovascular events and mortality compared with patients with more easily controlled hypertension. Secondary causes of hypertension, including obstructive sleep apnea, primary aldosteronism, renovascular disease, are common in patients with RHTN and often coexist in the same patient. In addition, RHTN is often complicated by metabolic abnormalities. Patients with RHTN require a thorough evaluation to confirm the diagnosis and optimize treatment, which typically includes a combination of lifestyle adjustments, and pharmacologic and interventional treatment. Combination therapy including a diuretic, a long-acting calcium channel blocker, an angiotensin-converting enzyme inhibitor, a beta blocker, and a mineralocorticoid receptor antagonist where warranted is the classic regimen for patients with treatment-resistant hypertension. Mineralocorticoid receptor antagonists like spironolactone or eplerenone have been shown to be efficacious in patients with RHTN, heart failure, chronic kidney disease, and primary aldosteronism. Novel interventional therapies, including baroreflex activation and renal denervation, have shown that both of these methods may be used to lower blood pressure safely, thereby providing exciting and promising new

    High blood pressure is very prevalent worldwide, as well as vitamin D deficiency. There are several observation data that support the concept that vitamin D is involved in the pathogenesis of hypertension. Also some clinical data demonstrate positive effect of vitamin D therapy on hypertension. We studied serum levels of vitamin D and its association with blood pressure in 30 hypertensive patients and 20 age and socioeconomic status matched healthy controls. There was no statistically significant difference in serum vitamin D levels in the group of patients compared with controls. In patients group, patients with body mass index (BMI) > 30 kg/m 2 showed statistically significant decrease in serum vitamin D levels as compared to those with BMI ≤ 30 kg/m 2 (P = 0.021). There was no significant association between serum vitamin D levels and age, systolic and diastolic blood pressure in the group of patients. A negative correlation between serum vitamin D levels and BMI was found in patients group (P = 0.045). In conclusion, no association between serum levels of vitamin D and blood pressure in hypertensive patients, but it is statistically associated with BMI. Further large scale studies are needed putting in consideration the effect of genetic factor

    The minor alleles of 3 FOXO3 single nucleotide polymorphisms (SNPs)- rs2802292 , rs2253310 , and rs2802288 -are associated with human longevity. The aim of the present study was to test these SNPs for association with blood pressure (BP) and essential hypertension (EHT). In a primary study involving Americans of Japanese ancestry drawn from the Family Blood Pressure Program II we genotyped 411 female and 432 male subjects aged 40-79 years and tested for statistical association by contingency table analysis and generalized linear models that included logistic regression adjusting for sibling correlation in the data set. Replication of rs2802292 with EHT was attempted in Japanese SONIC study subjects and of each SNP in a meta-analysis of genome-wide association studies of BP in individuals of European ancestry. In Americans of Japanese ancestry, women homozygous for the longevity-associated (minor) allele of each FOXO3 SNP had 6mm Hg lower systolic BP and 3mm Hg lower diastolic BP compared with major allele homozygotes (Bonferroni corrected P 0.05, respectively). Frequencies of minor allele homozygotes were 3.3-3.9% in women with EHT compared with 9.5-9.6% in normotensive women ( P = 0.03-0.04; haplotype analysis P = 0.0002). No association with BP or EHT was evident in males. An association with EHT was seen for the minor allele of rs2802292 in the Japanese SONIC cohort ( P = 0.03), while in European subjects the minor allele of each SNP was associated with higher systolic and diastolic BP. Longevity-associated FOXO3 variants may be associated with lower BP and EHT in Japanese women.

    Objective: To identify the factors that predispose to ischemic versus hemorrhagic stroke in hypertensive patients. Materials and Methods: All the hypertensive patients, who were registered in AKUH acute stroke outcome data base, over a period of 22 months, were identified and from this cohort the patients with first ever stroke were selected. The data regarding demographics, stroke type (ischemic vs. hemorrhagic), pre-existing medical problems, laboratory and radiological investigations was recorded and analyzed. Results: Five hundred and nineteen patients with either ischemic stroke or parenchymal hemorrhage were registered over a period of 22 months. Three hundred and forty-eight patients (67%) had hypertension and of these, 250 had first ever stroke at the time of admission. Presence of diabetes mellitus (OR: 3.76; Cl:1.67-8.46) and ischemic heart disease (OR: 6.97; Cl:1.57-30.98) were found to be independent predictors of ischemic strokes. Conclusion: Presence of diabetes mellitus and ischemic heart disease predict ischemic stroke in a patient with hypertension. (author)

    To study the prevalence and significance of left ventricular (LV) diastolic dysfunction in mild to moderate systemic hypertension (HT), cardiac blood pool imagings with Tc-99 m were obtained in 10 normal subjects and 27 patients with HT. The patients with HT did not show any evidence of coronary heart disease, renal insufficiency, cerebrovascular accident or diabetes mellitus. They were divided into 3 groups; (1) HT-1 (n=10): without evidence of echocardiographic (UCG) and electrocardiographic (ECG) left ventricular hypertrophy (LVH), (2) HT-2 (n=8): with evidence of ECG-LVH without UCG-LVH, (3) HT-3 (n=9): with evidence of UCG-LVH. UCG-LVH was defined when posterior or interventricular septal tall thickness exceeded 13 mm at end-diastole. From UCG findings LV mass was calculated and from UCG findings and auscultating brachial systolic pressure LV peak-systolic wall stress (WS) was obtained. Cardiac blood pool imagings were performed at modified LAO at rest and during exercise stress. Indices of LV systolic function (rest ejection fraction, mean ejection rate during the first third of ejection and exercise ejection fraction response) were essentially similar in normal subjects and all HT groups. In contrast, LV diastolic filling rate during the first third of diastole (1/3 FR mean) decreased significantly in any group of HT, and it was prominent in HT-3. In patients with HT, 1/3 FR mean did not correlate with blood pressure, LV peak-systolic WS, LV systolic functions and LV end-diastolic volume. But it correlated inversely with LV mass (r=-0.84). These results suggest that impairment of early diastolic LV filling can be detected before systolic cardiac impairment and LVH develop, and it is, at least in part, relate to the LV mass. (author)

    Rectal variations are reported in the natural history of high-tension. For example hypertension is significantly more prevalent in blacks than whites. Endothelial cells are important regulators of vasculars tone and homeostasis, in part through secretions of vasoactive substances including endothelin-I (ET-1), a small peptide with potent vaspressor actions in black hypertensive and normotensive whites. Since ET-I might play a significant role to the development and severity of hypertension in the indigenous Arab population of United Arab Emirates; we investigated the circulatory levels of ET-1 in the homogenous population. ET-I levels were measured in plasma samples from 60 unteated hypertensive Arabs and compared with 60 age and sex matched normotensive controls. ET-I levels were significantly higher in hypertensive (10.1+-pmol/L) than normtensives (mean 2.2+-0.5 pmol/L). Body mass index (BMI) was slightly higher among the hypertensive. For all subjects these levels significantly (P<0.001) correlated with systolic blood pressure and less significantly (P<0.05) with diastolic blood pressure and body weight. The correlation with ET-1 and both systolic and diastolic blood pressure with persistently significant after adjusting for BMI. Plasma concentration of ET-I are significantly higher in hypertensive Gulf Arabs as compared with reported levels in which hypertensives and ET-I could be a risk factor for cardiovascular diseases in this population. The endothelial sate might be particularly important with respect to hypertension in this racial group and merits further study. (author)

    An exaggerated accumulation of type I and type III fibrillar collagens occurs throughout the free wall and interventricular septum of patients with primary hypertension and left ventricular hypertrophy (LVH). In the present study the serum concentration of procollagen type III amino terminal peptide (PIIIP) was measured to determine the value of this peptide as a potential marker of ventricular fibrosis in hypertensive patients, particularly those with LVH. The study population consisted of patients with never-treated mild to moderate essential hypertension and 30 normotensive control subjects. Clinical, echocardiographic, electrocardiographic and biochemical parameters were assessed in all patients. Heart rate, body mass index and levels of blood pressure were increased in hypertensives, particularly those with LVH, compared to normotensive controls. Posterior wall thickness, left ventricular (LV) mass and LV mass index, and serum PIIIP concentration were also increased in hypertensives, with significant differences between the two hypertensive groups. The ratio between maximal early and late transmitral flow velocity measured during diastole was lower in hypertensives, particularly those with LVH, than in normotensive controls. The increase in PIIIP indicates that type III collagen synthesis increases in hypertensives, particularly those with LVH, implying that alterations in the heart in hypertension are the result not solely of hypertrophied LV muscle, but also of increased collagen deposition within the ventricular wall and around the coronary vessels. Thus, measurement of serum PIIIP could be a practical and useful tool in the non-invasive assessment of myocardial remodeling in hypertension. Copyright © 2014 Sociedade Portuguesa de Cardiologia.

    Management of arterial hypertension in the hyperacute period immediately after stroke ictus remains controversial. Extremes of blood pressure (BP) are associated with poor outcomes in all stroke subtypes. Severely hypertensive patients likely benefit from modest BP reductions, but aggressive BP reduction may worsen outcome. Although little evidence is currently available to definitively establish guideline recommendations for optimal BP goals at stroke presentation, recently published research is shedding some light on how to approach management of BP after stroke. Antihypertensive treatment should probably be deferred in ischemic stroke patients except in cases of severe hypertension or when thrombolytic therapy is warranted and the patient's BP is above acceptable levels. Hypertensive hemorrhagic stroke patients may benefit from modest BP reductions. Relative hypotension causing regional hypoperfusion is an increasingly understood concept immediately following ischemic or hemorrhagic stroke, emphasizing the need for careful titration of appropriate medications to minimize fluctuations in BP for treated patients. Ongoing trials will improve our current knowledge regarding BP management after ischemic and hemorrhagic stroke.

    The progression of hypertensive heart disease leads to the left ventricular diastolic dysfunction (LVDD), which is associated with increased cardiovascular morbidity and mortality. The purpose of this analysis is to explore the determinants for LVDD in patients with hypertension. This is a secondary analysis of data of Impedance Cardiography in the Evaluation of Left Ventricular Diastolic Dysfunction in Patients with Arterial Hypertension (IMPEDDANS) Study. Mann-Whitney and Chi-square tests were used for univariable analysis. Multiple logistic regression was used to model for LVDD occurrence and discriminative capacity of the model assessed by the value of the area under the curve given by the receiver-operating characteristic curve. Older age (65 vs. 58 years, p<0.001), longer duration of hypertension (160 vs. 48 months, p<0.001), uncontrolled hypertension (59.8 vs. 15.9%, p<0.001), tobacco smoking (17.8 vs. 3.8%, p=0.016), higher systolic blood pressure (133 vs. 124mmHg, p=0.001) and slower heart rate (62 vs. 66bpm, p=0.023) were associated with LVDD. Multivariate model identified uncontrolled hypertension (AdjOR 36.90; 95% CI 7.94-171.58; p<0.001), smoking (AdjOR 6.66; 95% CI 1.63-27.26; p=0.008), eccentric hypertrophy (AdjOR 3.59; 95% CI 0.89-14.39; p=0.072), duration of hypertension (AdjOR 1.03; 95% CI 1.02-1.05; p<0.001) and concentric remodeling (AdjOR 0.19; 95% CI 0.04-0.93; p=0.041) as the more determinant for occurrence of LVDD. The discriminative capacity of the model was AUC=0.95 (95% CI 0.91-0.98). The occurrence of LVDD in hypertensive patients was strongly associated to long-lasting, uncontrolled hypertension, tobacco smoking, concentric remodeling and eccentric hypertrophy.

    The aim of this study was to analyze frequency of restless legs syndrome (RLS) in patients with hypertension and diabetes mellitus. It was analyzed 120 subjects (from Health Center Živinice/Family Medicine Department) through a survey conducted in the period from March to June 2015, of which 30 (8 men/22 women). Subjects were 30 patients with longtime hypertension (HT)(18 men/12 women), 30 patients with diabetes mellitus (DM) type I or II (9 men/21 women), 30 patients with long standing DM type I or II and HT (12 men /18 women), and 30 control subjects (12 men/18 women). RLS were evaluated by questionnaire - International RLS Study Group Criteria. The average age of patients in the group with HT was 58.70 ± 9.07, in the group with DM 48.43 ± 15.37, and in the group of patients with HT and DM 63.90 ± 7.49 years. In the control group mean age was 52.76 ± 14.83 years. Statistical data were analyzed in Excel and SSPS statistical program. RLS was identified in 10 (30%) of those with HT; 7 (21%) in patients with DM, and 10 (30%) in patients with HT+DM. In the control group RLS was verified in 4 (12%) patients. Comparing the results, it was observed significant difference between the HT and the control group (p=0.0012) and HT+ DM and control group (p=0.0012). The frequency of RLS between DM and the control group was not significantly significant (p=0.107). RLS is frequent in patients with hypertension (30%), hypertension+ diabetes mellitus (30%), and patients with DM (21%).

    To estimate renal disease in recently diagnosed hypertensive patients, and to identify factors related to renal disease. Cross-sectional study, with 425 hypertensive patients recently diagnosed in primary health care; renal disease was estimated with serum creatinine, albumin/creatinine index and glomerular filtration rate (GFR). We analyzed cardiovascular risk factors (CRF), subclinical organ injury and cardiovascular disease following the criteria of the 2007 European Guide of Hypertension. Average age: 58,96 +/- 12,73 years old, 63,3% male. We found dyslipemia in 80%, abdominal obesity in 49% and metabolic syndrome in 36% patients. These patients showed increased serum creatinine 3,3%, a reduction in GFR 9,6%, hidden renal disease 6,4%, microalbuminuria 7,5% and nephropathy 2,4%. Hypertensive patients with renal disease (17,88%) were older, with higher systolic pressure, higher incidence of metabolic syndrome, abnormal carotid intima-media thickness and ankle-arm index, and presence of cardiovascular disease. Variables associated with renal disease were metabolic syndrome (odds ratio = 11,12) and ankle-arm index (odds ratio = 17,55). Variables related to creatinina were sex, ankle-arm index and metabolic syndrome; variables related to GFR were sex, age, ankle-arm index, metabolic syndrome and body mass index (BMI); variables related with albumin/creatinine index included diabetes mellitus. Renal disease is detected in about 2 out of 10 hypertensive patients, when, besides serum creatinina, we analyze albumin/creatinine index and GFR. Metabolic syndrome and ankle-arm index are the main variables associated with renal disease. Copyright 2009 Elsevier España, S.L. All rights reserved.

    Results of monitoring of awareness level in dispensary patients with arterial hypertension (AH) are given in the article. The objective of the study was to investigate awareness level of dispensary patients with hypertension in Sumy as for the course of their disease, implementation of preventive measures, diagnosis and treatment, and to use the obtained information in the process of management of healthcare quality. The results of close-ended questionnaires were used in the capacity of materials. A total of 2019 patients were surveyed. Despite the high level of patients' awareness of AH course and possible complications, the survey showed insufficient level of their own responsibility for their health. The main reasons for poor adherence to doctor's recommendations are forgetfulness, lack of time, reluctance. Measures were developed to increase awareness level in patients with AH by means of strengthening awareness-raising activities and communications, as well as creation and implementation of effective targeted health-and-social programs.

    BACKGROUND: Existing data on gastric emptying and small-intestinal transit rates in portal-hypertensive patients are scarce and contradictory, and so far, the motor function of the colon has not been assessed in these patients. In this study we evaluated the propulsive effect of all main segments...... of the gastrointestinal tract in patients with well-characterized portal hypertension. METHODS: Eight patients with a postsinusoidal hepatic pressure gradient of at least 13 mmHg and eight age- and sex-matched healthy controls participated in the study. Gastric emptying, small-intestinal transit, and colonic transit...... rates were evaluated in all subjects by means of a gamma camera technique. The technique was also used to measure the frequency of antral contractions. RESULTS: No difference was observed in gastric mean emptying time or small-intestinal mean transit time of liquid and solid markers between patients...

    Objective: To investigate the plasma adrenomedullin (ADM) concentrations in hyperthyroid patients with or without pulmonary hypertension. Methods: Plasma ADM levels were measured with RIA in: (1) 30 hyperthyroid patients without pulmonary hypertension, (2) 27 hyperthyroid patients with pulmonary, hypertension, and (3) 32 controls. Results: (1) In this study, 27 of the 57 hyperthyroid patients were complicated with pulmonary hypertension (47.37%), (2) Plasma ADM concentrations in the patients with pulmonary hypertension were significantly higher than those in patients without pulmonary hypertension and controls (P 3 , T 4 (thyroid hormones) were positively correlated with those of ADM while there were no correlations in controls. Conclusion: Plasma ADM concentrations increased in hyperthyroid patients, especially in those complicated with pulmonary hypertension. The clinicians should look for pulmonary hypertension in hyperthyroid patients with substantially elevated levels of ADM. (authors)

    Over the last four years the authors performed transcatheter embolization of the splenic artery by Gianturco coils in 32 consecutive cirrhotic patients with portal hypertension, splenomegaly, cytopenia and gastro-esophageal varices endoscopically proved. This procedure was especially useful for treatement of splenomegaly and cytopenia because a constant reduction of spleen dimensions and increase in platelet count were registered. The effectiveness of transcatheter embolization and follow-up are based on clinic, hematologic and sonographic findings. Sonographic monitoring is believed to be very useful both to evaluate splenomegaly and signs of portal hypertension and to reveal splenic complications (abscesses). Severe complications have been never registered

    Gaojun Cai

    Full Text Available Epidemiological studies have shown that E-selectin gene polymorphisms (A561C and C1839T may be associated with essential hypertension (EH, but the results are conflicting in different ethnic populations. Thus, we performed this meta-analysis to investigate a more authentic association between E-selectin gene polymorphisms and the risk of EH.We searched the relevant studies for the present meta-analysis from the following electronic databases: PubMed, Embase, Cochrane Library, Google Scholar, Web of Science, Wanfang Data, and China National Knowledge Infrastructure (CNKI. Odds ratios (OR with 95% confidence interval (CI were used to evaluate the strength of the association between E-selectin gene polymorphisms and EH susceptibility. The pooled ORs were performed for dominant model, allelic model and recessive model. The publication bias was examined by Begg's funnel plots and Egger's test.A total of eleven studies met the inclusion criteria. All studies came from Asians. Ten studies (12 cohorts evaluated the A561C polymorphism and EH risk, including 2,813 cases and 2,817 controls. The pooled OR was 2.280 (95%CI: 1.893-2.748, P<0.001 in dominant model, 5.284 (95%CI: 2.679-10.420, P<0.001 in recessive model and 2.359 (95%CI: 1.981-2.808, P = 0.001 in allelic model. Four studies (six cohorts evaluated C1839T polymorphism and EH risk, including 1,700 cases and 1,681 controls. The pooled OR was 0.785 (95%CI: 0.627-0.983, P = 0.035 in dominant model, 1.250 (95%CI: 0.336-4.652, P = 0.739 in recessive model and 0.805 (95%CI: 0.649-0.999, P = 0.049 in allelic model.The current meta-analysis concludes that the C allele of E-selectin A561C gene polymorphism might increase the EH risk in Asian population, whereas the T allele of E-selectin C1839T gene polymorphism might decrease the EH risk.

    Anomalous pulmonary venous return is an uncommon congenital malformation, and may be partial or total. Partial anomalous pulmonary venous return (PAPVR) is more common than total anomalous pulmonary venous return, and is often associated with other congenital cardiac anomalies. Whilst many patients with PAPVR remain asymptomatic, some may present in later age with symptoms related to left-to-right shunt, right heart failure and pulmonary hypertension. We report two cases of PAPVR detected on Computed Tomography Pulmonary Angiogram (CTPA) for the work up of pulmonary hypertension. The cases demonstrate that, although uncommon, partial anomalous pulmonary venous return can be a contributing factor to pulmonary hypertension and pulmonary veins should be carefully examined when reading a CTPA study.

    Purpose: To study the vasomotor responses of the renal microcirculation in patients with essential hypertension.Methods: We studied the reactivity of the renal microcirculation to papaverine, with intraarterial Doppler and quantitative arteriography, in 34 renal arteries of 19 hypertensive patients without significant renal artery stenosis. Isosorbide dinitrate was given to maximally dilate proximal renal arteries. APV (average peak blood flow velocity) was used as an index of renal blood flow.Results: Kidneys could be divided into two distinct subgroups based on their response to papaverine. An increase in APV of up to 55% occurred in 21 kidneys, an increase > 55% in 13 kidneys. Within each group the values were normally distributed. Both baseline APV and the effect of papaverine on mean velocity differed significantly between groups.Conclusion: There seems to be a subgroup of patients with essential hypertension that has an impaired reactivity to papaverine, consistent with a functional impairment of the renal microcirculation. Further studies are required to determine whether this abnormality contributes to or results from elevated blood pressure

    Objective: To explore the possible mechanisms of neurogenic hypertension. Methods: With the guide of modern imaging, the hypertensive animal model of pulsatile neurovascular compression was established by fixation of balloon at the entry zone of the ninth and tenth cranial nerves of the left ventrolateral medulla oblongata. Blood pressure and heart rate data were collected at preoperation and one hour, 2 weeks, 4 weeks, and 6 weeks of postoperation. Results: The results showed that SBP at postoperation rose by 27.3%, 26.1%, 25.4% and 27.4%, respectively; DBP rose by 18.8%, 20.8%, 20.0% and 20.2%, respectively; MAP rose by 24.2%, 24.1%, 23.2% and 24.8%, respectively; HR rose by 34.9%, 26.7%, 26.9% and 26.1% respectively. Statistically, SBP, DAP, MAP and HR of postoperation significantly increased compared with that of preoperation in hypertension group (F = 9.044, 12,679, 11.306, 16.536, P 0.05). Conclusion: Essential hypertension may by caused by neurovascular compression of ninth and tenth cranial nerves of the left ventrolateral medulla oblongata at the REZ

    Full Text Available Abstract Background The aim of this study was to determine if hypertensive type 2 diabetic patients, when compared to patients with essential hypertension have an increased left ventricular mass index (LVMI and a worse diastolic function, and if this fact would be related to 24-h pressoric levels changes. Methods Ninety-one hypertensive patients with type 2 diabetes mellitus (DM (group-1 [G1], 59 essential hypertensive patients (group-2 [G2] and 26 healthy controls (group-3 [G3] were submitted to 24-h Ambulatory Blood Pressure Monitoring (ABPM and echocardiography (ECHO with Doppler. We calculated an average of fasting blood glucose (AFBG values of G1 from the previous 4.2 years and a glycemic control index (GCI (percentual of FBG above 200 mg/dl. Results G1 and G2 did not differ on average of diurnal systolic and diastolic BP. However, G1 presented worse diastolic function and a higher average of nocturnal systolic BP (NSBP and LVMI (NSBP = 132 ± 18 vs 124 ± 14 mmHg; P 2; P 165 mg/dl showed an additional risk of LVH (P Conclusion This study suggests that hyperglycemia and higher NSBP levels should be responsible for an increased prevalence of LVH in hypertensive patients with Type 2 DM.

    Full Text Available Background: aging-associated diseases contribute to morbidity and mortality in the population; therefore, it is necessary to develop intervention strategies to prevent and/or minimize their consequences. Objectives: to evaluate the effectiveness of a cognitive-behavioral intervention aimed at older hypertensive patients treated in primary care in Cardenas and Santiago de Cuba municipalities during 2011-2013. Methods: an intervention study of older adults with hypertension was conducted in two municipalities: Santiago de Cuba and Cárdenas. The intervention group was composed of 399 older patients living in the catchment areas of the Carlos Juan Finlay and Héroes del Moncada polyclinics while the control group included 377 older adults served by the Julian Grimau and Jose Antonio Echeverría polyclinics. The intervention consisted of a systematic strategy to increase knowledge of the disease in order to change lifestyles. Results: in the intervention group, there were more patients with sufficient knowledge of the disease (OR: 1.82, greater control of hypertension (OR: 1.51 and better adherence to treatment (OR: 1.70. By modeling the explanatory variables with hypertension control, being in the intervention group (OR: 0.695 and adhering to treatment (OR: 0.543 were found to be health protective factors. Conclusion: the congnitive-behavioral intervention for older adults treated in primary care of the municipalities studied was effective in improving blood pressure control since it contributed to a greater adherence to treatment.

    Strict adherence to personal health recommendations is necessary to improve the clinical control of arterial hypertension. To identify predictors of the behavior to avoid the "consumption of restricted foods" in a sample of hypertensive patients from Tamaulipas, Mexico. Participants were 183 patients with arterial hypertension diagnosis, who completed two self-administered questionnaires and different questions regarding adherence and self-care behaviors. A trajectory analysis was used for the interpretation of data. Less tolerance to frustration, a major affective social support and a lower body mass index were behavior predictors to avoid the consumption of restricted foods (pBS= 0.294, χ2/gl= 1.417, GFI = 0.993, AGFI = 0.965, NFI = 0.934, IFI = 0.980 y SRMR = 0.040), explaining approximately 20% of the variance in the study behavior. The study of adherence and self-care behaviors demands to identify what and how some personal and interpersonal variables are influencing in their daily practice, which can contribute to improve the interdisciplinary interventions programs in clinical and communitarian settings for attending patients living with arterial hypertension.

    Hypertension is one of the most important cardiovascular risk factor but its control is still a challenge for physicians all around the world. Control of blood pressure can reduce cardiovascular morbidity and mortality, so the compliance to antihypertensive drugs and life style modification play an important role for the control of hypertension. This analytical (cross-sectional) study was conducted to assess prevalence of control of hypertension among hypertensive patients and to assess the relationship of control of hypertension with factors like compliance to antihypertensive drugs, salt restriction and exercise among the hypertensive patients. This study was conducted at outpatient clinic of medicine at Shahina Jamil Hospital Abbottabad from April 2007 to September 2007. Eighty-nine patients seen in the outpatient clinic of medicine were enrolled in the study. All the patients with age 15 years or above, diagnosed as a case of systemic hypertension were included. Among eighty nine patients, 67 were female and 22 were male with mean age of 55.8+-13.4 years, mean systolic and diastolic blood pressure of 160+-28.6 and 97.8+-14.1 mm Hg respectively, and pulse rate of 85.9+-11.4 per minutes. Out of 89 patients, 25.8% were having controlled hypertension, 48.3% were compliant and 51.7% were not compliant to antihypertensive drugs, 55.1% were having salt restriction and 44.9% were having no salt restriction and 23.6% were used to do physical activity while 76.4% were not used to do physical activity. In group A consisted of patients with controlled hypertension, 95.7% patients were compliant to antihypertensive patients, 95.7% were having salt restriction and 43.5% were used to do physical activity. In group B consisted of patients with uncontrolled hypertension, only 31.8% were compliant to antihypertensive drugs, 40.9% were having salt restriction, 16.7% were used to do physical activity. Hypertension can be controlled if the hypertensive patients have good compliance

    Hypertension or high blood pressure is on the rise. Not only does it affect the elderly but is also increasingly spreading to younger sectors of the population. Treating this condition involves exhaustive monitoring of patients. The current mobile health services can be improved to perform this task more effectively. To develop a useful, user-friendly, robust and efficient app, to monitor hypertensive patients and adapted to the particular requirements of hypertension. This work presents BPcontrol, an Android and iOS app that allows hypertensive patients to communicate with their health-care centers, thus facilitating monitoring and diagnosis. Usability, robustness and efficiency factors for BPcontrol were evaluated for different devices and operating systems (Android, iOS and system-aware). Furthermore, its features were compared with other similar apps in the literature. BPcontrol is robust and user-friendly. The respective start-up efficiency of the Android and iOS versions of BPcontrol were 2.4 and 8.8 times faster than a system-aware app. Similar values were obtained for the communication efficiency (7.25 and 11.75 times faster for the Android and iOS respectively). When comparing plotting performance, BPcontrol was on average 2.25 times faster in the Android case. Most of the apps in the literature have no communication with a server, thus making it impossible to compare their performance with BPcontrol. Its optimal design and the good behavior of its facilities make BPcontrol a very promising mobile app for monitoring hypertensive patients.

    In a group of older, arteriosclerotic hypertensive patients treated with an extract of Rauwolfia over a long period, a mild hypotensive effect was noted after weeks, or occasionally months, of therapy. No dramatic responses were seen, but the so-called “tranquilizing” effect was readily apparent and was appreciated by the patients. Side effects were usually relatively minor, were transient and rarely necessitated stopping the drug. PMID:13209377

    The growing epidemic of metabolic syndrome has been related to the increased use of fructose by the food industry. In fact, the use of fructose as an ingredient has increased in sweetened beverages, such as sodas and juices. We thus hypothesized that fructose intake by hypertensive rats would have a worse prognosis in developing metabolic disorder and non-alcoholic fatty liver disease. Male Wistar and SHR rats aged 6weeks were given water or fructose (10%) for 6weeks. Blood glucose was measured every two weeks, and insulin and glucose sensitivity tests were assessed at the end of the follow-up. Systolic blood pressure was measure by plethysmography. Lean mass and abdominal fat mass were collected and weighed. Liver tissue was analyzed to determine interstitial fat deposition and fibrosis. Fasting glucose increased in animals that underwent a high fructose intake, independent of blood pressure levels. Also, insulin resistance was observed in normotensive and mostly in hypertensive rats after fructose intake. Fructose intake caused a 2.5-fold increase in triglycerides levels in both groups. Fructose intake did not change lean mass. However, we found that fructose intake significantly increased abdominal fat mass deposition in normotensive but not in hypertensive rats. Nevertheless, chronic fructose intake only increased fat deposition and fibrosis in the liver in hypertensive rats. We demonstrated that, in normotensive and hypertensive rats, fructose intake increased triglycerides and abdominal fat deposition, and caused insulin resistance. However, hypertensive rats that underwent fructose intake also developed interstitial fat deposition and fibrosis in liver. Copyright © 2016 Elsevier Inc. All rights reserved.

    The term masked hypertension (MH) should be used for untreated individuals who have normal office blood pressure but elevated ambulatory blood pressure. For treated patients, this condition should be termed masked uncontrolled hypertension (MUCH). Masked uncontrolled hypertension (MUCH) has gone unrecognized because few studies have used 24-h ABPM to determine the prevalence of suboptimal BP control in seemingly well-treated patients, and there are few such studies in large cohorts of treated patients attending usual clinical practice. This is important because masked hypertension is associated with a high risk of cardiovascular events. This study was conducted to obtain more information about the association between hypertension and other CV risk factors, about office and ambulatory blood pressure (BP) control as well as on cardiovascular (CV) risk profile in treated hypertensive patients, also to define the prevalence and characteristics of masked uncontrolled hypertension (MUCH) among treated hypertensive patients in routine clinical practice. In this study 2514 male and female patients were included during a period of 5 years follow up. All patients have ambulatory blood pressure monitoring (ABPM) for at least 24h. We identified patients with treated and controlled BP according to current international guidelines (clinic BP, 140/90mmHg). Cardiovascular risk assessment was based on personal history, clinic BP values, as well as target organ damage evaluation. Masked uncontrolled hypertension (MUCH) was diagnosed in these patients if despite controlled clinic BP, the mean 24-h ABPM average remained elevated (24-h systolic BP ≥130mmHg and/or 24-h diastolic BP ≥80mmHg). Patients had a mean age of 60.2+10 years, and the majority of them (94.6%) were followed by specialist physicians. Average clinic BP was 150.4+16/89.9+12 mmHg. About 70% of patients displayed a very high-risk profile. Ambulatory blood pressure monitoring (ABPM) was performed in all recruited

    We investigated the clinical characteristics of a pediatric population with hemato-oncological disease and intracranial hypertension, analyze the therapeutic response and outcome, and compare its characteristics with respect to a control group with idiopathic intracranial hypertension. We retrospectively analyzed patients with hemato-oncological disease and secondary intracranial hypertension in our center during the past five years. We compared these individuals with a historical cohort with idiopathic intracranial hypertension from our institution (control group). We identified eight patients, all with leukemia, and 21 controls. Mean age at diagnosis was 10.6 years, and 62% of individuals were female. Most of them were under treatment with drugs (62% corticosteroids, 75% active chemotherapy). Mean opening pressure of cerebrospinal fluid was 35 cm H 2 O. All had headache, but only 28% complained of visual symptoms. Only 12.5% exhibited papilledema at the time of diagnosis (versus 71% in controls). All of them were treated with acetazolamide, with average therapy duration of nine months, and all had a favorable outcome (versus 57% of controls who needed second-line treatment). None of them showed long-term visual complications (versus 20% of controls). Patients with hemato-oncological disease and secondary intracranial hypertension may not develop typical symptomatology. Thus, diagnosis and recognition of this entity among this cohort may be difficult. Associated factors are diverse and do not show an obvious causal relationship. A high index of suspicion must be maintained for diagnosis, because a favorable outcome is expected with prompt treatment. Acetazolamide is effective as a first-line therapy and caused few side effects. Copyright © 2017 Elsevier Inc. All rights reserved.

    The relation between hypertension and cognitive impairment is an undisputable fact. The aims of this study were to determine the prevalence of cognitive impairment in hypertensive patients, to identify the most affected cognitive domain, and to observe the association with different parameters of hypertension and other vascular risk factors. A multicentre study was carried out, and 1281 hypertensive patients of both genders and ≥21 years of age were included. Data on the following parameters were obtained: cognitive status (Minimal Cognitive Examination), behavioural status (Hospital Anxiety and Depression Scale), blood pressure, anthropometry, and biochemical profile. The average age was 60.2±13.5 years (71% female), and the educational level was 9.9±5.1 years. Global cognitive impairment was seen in 22.1%, executive dysfunction in 36.2%, and semantic memory impairment in 48.9%. Cognitive impairment was higher in males (36.8% vs. 30.06%) within both the 70-79-year-old and the ≥80-year-old (50% vs. 40%) age groups. Abnormal Clock Drawing Test results were related to high pulse pressure (p24), 29.4% presented executive dysfunction, and 41.5% semantic memory impairment. Cognitive impairment was higher in hypertensive patients than in the general population. Executive functions and semantic memory were the most affected cognitive domains. High systolic blood pressure and pulse pressure were associated with abnormal results in cognitive tests. Copyright © 2018 SEH-LELHA. Publicado por Elsevier España, S.L.U. All rights reserved.

    Microalbuminuria is a known complication of diabetes mellitus but it is also a cardiovascular risk factor commonly present among hypertensive (non diabetic) population. The prevalence of microalbuminuria is variable and it has been never estimated in our region. The aim of this study has been to determine the prevalence of microalbuminuria in hypertensive (non diabetic) and diabetic population in Extremadura (Spain). The study included diabetic patients and non-diabetic hypertensive ones randomly selected. Microalbuminuria was measured in every patient using albumin/creatinin reactive stick in fasting first morning urine. Whenever possible microalbuminuria was confirmed in laboratory by microalbuminuria/creatinina coefficient in first morning urine samples. A total of 979 patients (mean age [SD], 67.9 [10.8] years; 409 men and 570 women, 505 diabetics) were studied. The presence of microalbuminuria was found in 12.4% of hypertensive patients and in 21.4% of diabetic patients (p < 0.001). Hypertensives and normotensive diabetics showed a similar prevalence of microalbuminuria (13.3%, not significant), but it tripled in hypertensive diabetics (33.8; p < 0.01). Glicemic control was not different for microalbuminuric diabetic patients and non microalbuminuric ones. The patients receiving rennin-angiotensin axis blocking drugs do not showed less prevalence of microalbuminuria (hypertensives 10.5%, diabetics 23.5%). Microalbuminuria was confirmed in 65.4% of patients. The prevalence of microalbuminuria in Extremadura seems to be high either in diabetics or non diabetic hypertensive patients. The finding of microalbuminuria in diabetics patients correlates with hypertension but do not with glicemic control. The prevalence of microalbuminuria is high in spite of using rennin-angiotensin axis blocking drugs.

    Gastrointestinal bleeding related to portal hypertension is a serious complication in patients with liver cirrhosis. Most patients bleed from esophageal or gastric varices, but bleeding from ectopic varices or portal hypertensive gastropathy is also possible. The management of acute bleeding has changed over the last years. Patients are managed with a combination of endoscopic and pharmacologic treatment. The endoscopic treatment of choice for esophageal variceal bleeding is variceal band ligation. Bleeding from gastric varices is treated by injection with cyanoacrylate. Treatment with vasoactive drugs as well as antibiotic treatment is started before or at the time point of endoscopy. The first-line treatment for primary prophylaxis of esophageal variceal bleeding is nonselective beta blockers. Pharmacologic therapy is recommended for most patients; band ligation is an alternative in patients with contraindications for or intolerability of beta blockers. Treatment options for secondary prophylaxis include variceal band ligation, beta blockers, a combination of nitrates and beta blockers, and combination of band ligation and pharmacologic treatment. A clear superiority of one treatment over the other has not been shown. Bleeding from portal hypertensive gastropathy or ectopic varices is less common. Treatment options include beta blocker therapy, injection therapy, and interventional radiology. PMID:27335828

    A hypertensive response to exercise (HRE) is known to be associated with higher risk of heart failure and future cardiovascular events in patients with hypertension. Left atrial volume index (LAVI) is associated with the diastolic dysfunction, indicating exercise intolerance. Therefore, we investigated whether LAVI is relevant to HRE during cardiopulmonary exercise test (CPET). We studied 118 consecutive hypertensive patients (61 men, 57±11 years) and 45 normotensive control subjects (16 men, 54±8 years). Clinical characteristics, CPET, echocardiographic and laboratory findings were assessed at the time of enrollment. HRE was defined as maximum systolic blood pressure (SBP)⩾210 mm Hg in men and ⩾190 mm Hg in women. HRE was more prevalent in hypertensive patients compared with normotensive control subjects (50.8% vs. 20.0%, PHRE in normotensive control subjects, as were baseline SBP and LAVI in hypertensive group. In multivariate analysis, LAVI was found to be an independent predictor of HRE in hypertensive patients (P=0.020) but not in normotensive control subjects (P=0.936) when controlled for age, sex, body mass index and peak oxygen consumption. Higher LAVI, reflecting the duration and severity of increased left atrial pressure is independently associated with HRE in hypertensive patients, but not in normotensive control subjects.

    Full Text Available Background: Sildenafil, a phosphodiestase type 5 inhibitor, was approved in 2005 for the treatment of pulmonary arterial hypertension (PAH in adults, and is commonly used off-label for pediatric patients. Little is known, however, about sildenafil’s side effects in this population.Methods: Single institution, longitudinal survey-based study performed in an outpatient pediatric cardiology clinic. Pediatric patients on sildenafil (alone or in combination with other PH therapies completed questionnaires regarding frequency of vascular, gastrointestinal, neurologic and hematologic side effects. Results: Between January 2011 and May 2014, 66 pediatric patients with PH on sildenafil filled out 214 surveys, 32 patients (96 surveys on monotherapy, and 43 patients (118 surveys on sildenafil plus an endothelin receptor antagonist (bosentan or ambrisentan and/or a prostacyclin (epoprostenol or treprostinil. Overall, 30% of respondents identified at least one side effect. For all patients on sildenafil, incidence of side effects by system was 37% gastrointestinal, 35% vascular and 22% neurologic. For patients on sildenafil monotherapy, incidence of side effects by system was 24% gastrointestinal, 21% vascular and 18% neurologic compared to patients on combination therapy who reported an incidence of 48% gastrointestinal, 45% vascular and 25% neurologic.Conclusion: Incidence of vascular, gastrointestinal and neurologic side effect in pediatric patients on sildenafil therapy for pulmonary arterial hypertension was 30%. Side effects were more common in patients on combination therapy with an endothelin receptor antagonist and/or prostacyclin than in patients on sildenafil monotherapy.

    Hypertension is an atherosclerosis factor and is associated with cardiovascular risk. We investigated the relationship between hypertension and the presence, extent, and severity of coronary atherosclerosis in coronary computed tomographic angiography and cardiac events risk. Of 17 181 patients enrolled in the CONFIRM registry (Coronary CT Angiography Evaluation for Clinical Outcomes: An International Multicenter Registry) who underwent ≥64-detector row coronary computed tomographic angiography, we identified 14 803 patients without known coronary artery disease. Of these, 1434 hypertensive patients were matched to 1434 patients without hypertension. Major adverse cardiac events risk of hypertension and non-hypertensive patients was evaluated with Cox proportional hazards models. The prognostic associations between hypertension and no-hypertension with increasing degree of coronary stenosis severity (nonobstructive or obstructive ≥50%) and extent of coronary artery disease (segment involvement score of 1-5, >5) was also assessed. Hypertension patients less commonly had no coronary atherosclerosis and more commonly had nonobstructive and 1-, 2-, and 3-vessel disease than the no-hypertension group. During a mean follow-up of 5.2±1.2 years, 180 patients experienced cardiac events, with 104 (2.0%) occurring in the hypertension group and 76 (1.5%) occurring in the no-hypertension group (hazard ratios, 1.4; 95% confidence intervals, 1.0-1.9). Compared with no-hypertension patients without coronary atherosclerosis, hypertension patients with no coronary atherosclerosis and obstructive coronary disease tended to have higher risk of cardiac events. Similar trends were observed with respect to extent of coronary artery disease. Compared with no-hypertension patients, hypertensive patients have increased presence, extent, and severity of coronary atherosclerosis and tend to have an increase in major adverse cardiac events. © 2017 American Heart Association, Inc.

    Symmer's periportal fibrosis secondary to schistosomiasis is a common cause of portal hypertension worldwide. Data on the prevalence of gastric variances and portal hypertensive gastropathy in this group of patients with portal of hypertension is relatively scarce. The aim of this study was to determine the prevalence of gastric varices and portal hypertensive gastropathy in patients presenting with portal hypertension secondary to Symmer's periportal fibrosis. In a prospective study, upper gastrointestinal endoscopy was carried out to determine the prevalence of gastric varices and portal hypertensive gastropathy in patients with portal hypertension secondary to Symmer's fibrosis. Of 143 patients studied, 24 patients (16.8%) had gastric varices (grade I in 10.5%, grade Ii in 6.3%) and 31 patients (21.7%) had portal hypertensive gastropathy (mild in 11.2%, severe in 10.5%). Gastric varices were more prevalent in patients with grade I and II esophageal varices and portal hypertensive gastropathy was more prevalent in those with grade III and IV esophageal varices, but the differences were not statistically significant. We conclude that both gastric varices and portal hypertensive gastropathy seem to have a lower prevalence in patients with portal hypertension secondary to Symmer's periportal fibrosis when compared to reported data in patients with portal hypertension secondary to liver cirrhosis and non-cirrhotic portal fibrosis.

    Full Text Available Objectives: Our study aimed to estimate the rate of white coat hypertension (WCH and effect, and masked hypertension in patients attending a tertiary care hospital for 24 hour ambulatory blood pressure monitoring (24-h ABPM. Methods: A total of 231 adult patients were referred to the Department of Clinical Physiology at Sultan Qaboos University Hospital, Muscat, for ABPM, between January 2010 and June 2012. The following data were gathered and analyzed: demographic data, clinic blood pressure (BP measurements, and 24-h BP profile from ABPM. Thirty-two patients were excluded and the final analysis included 199 patients. Results: There were 105 (52.8% women and 94 (47.2% men studied. The mean age of patients was 46±15 years and most patients were overweight with a mean BMI of 29.6±5kg/m2. Around half of patients (53.8% were on one or more antihypertensive medications. WCH was found in 10.6% and white coat effect was found in 16% of patients. The majority of patients (57% with WCH were aged 40 years or above. Masked hypertension was present in 6% of patients and masked uncontrolled hypertension in 8.5% of patients. Conclusions: Our study showed that WCH and effect, and masked hypertension are common in hypertensive patients. Identifying these patients will have an impact on their management. However, the results of the study should be interpreted within the context of its limitations. Prospective randomized community and hospital-based studies should be conducted to estimate the true prevalence in the general population as well as in hypertensive patients.

    The reverse contrast examination of the system, carried out by means of superior arteriomesentericography, is the optimal method for diagnosing pathological changes in the portal channel of splenectomized patients with the syndrome of the extrahepatic form of portal hypertension. The selective catheterization of the superior mesenteric artery was made in 36 patients with the prerenal block of the portal system. In all cases the venous phase of portography was obtained, which served as a basis for selecting the amount of surgical intervention in these patients. Depending on the level of the block of the portal channel, the patients fell into 3 groups. The characteristic X-ray appearance of portal hypertension, manifested mainly by the presence of portoportal and portocaval collaterals, is described for each group. The thrombosis of the main vessels of the loose type of their structure excludes the possibility of portocaval anastomosis, while in the presence of the pronounced surgical trunk of the superior mesenteric vein vascular shunting may be recommended. Portal hypertension, in contrast to the normal state, requires prolonged contrast examination of the venous phase due to a slower portorenal blood flow

    Conclusions: ADMA is elevated in hypertensive patients. Elevated ADMA concentrations are associated with impaired endothelium functions, which are demonstrated by NO reduction in the sera of hypertensive patients. ADMA is correlated positively with the traditional cardiovascular risk factors. Also there was a strong significant negative correlation between NO and ADMA levels in the whole hypertensive groups.

    Background Hypertension is the main risk factor for cardiovascular diseases, affecting more than half the elderly population. It is essential to know if they have proper control of hypertension. The aim of this study was to identify the associated factors to masked uncontrolled hypertension and false uncontrolled hypertension in older patients. Methods Two-hundred seventy-three individuals (70.1 ± 6.7 years-old) had blood pressure (BP) measured at the office and by ambulatory BP monitoring (ABPM), with the definition of controlled group (C), individuals with high office BP and adequate ABPM, called white-coat effect group (WCE), uncontrolled (UC), and subjects with appropriate office BP and elevated ABPM denominated masked effect group (ME). Age, body mass index, diabetes, pulse pressure (PP) and BP dipping during sleep were evaluated (Kruskal-Wallis test and logistic regression models). Results Age was higher in UC than in C and ME (P ABPM PP was lower in C (48 ± 7 mmHg) and WCE (51 ± 6 mmHg) than in UC (67 ± 12 mmHg) and ME (59 ± 8 mmHg) (P ABPM favored the identification of a higher PP and a lower BP dipping during sleep in the masked effect and uncontrolled groups.

    Parenteral nutrition may protect patients unable to eat from malnutrition almost indefinitely. If fat is not also given EFAD will occur. This outlines a prospective study of 28 surgical patients on total intravenous fat-free nutrition to determine the developmental course of EFAD and the response to therapy. Twenty-eight patients ranging from newborn to 66 years receiving parenteral nutrition without fat had regular determinations of the composition of total plasma fatty acids and the triene/tetraene ratio using gas liquid chromatography. Physical signs of EFAD were looked for also. Patients found to have evidence of EFAD were treated with 10% Intralipid. Topical safflower oil was used in three infants. Total plasma fatty acid composition was restudied following therapy. In general, infants on fat-free intravenous nutrition developed biochemical EFAD within two weeks, but dermatitis took longer to become evident. Older individuals took over four weeks to develop a diagnostic triene/tetraene ratio (greater than 0.4; range 0.4 to 3.75). Therapeutic correction of biochemical EFAD took 7 to 10 days but dermatitis took longer to correct. Cutaneous application of safflower oil alleviated the cutaneous manifestations but did not correct the triene/tetraene ratio of total plasma fatty acids. These studies indicate that surgical patients who are unable to eat for two to four weeks, depending upon age and expected fat stores, should receive fat as a part of their intravenous regimen.

    Thiazide (hydrochlorothiazide,...) and thiazide-like (chlortalidone, indapamide,...) diuretics are widely used to treat hypertensive patients. There is growing evidence that these diuretics are not interchangeable and that it might be preferable to choose a thiazide-like diuretic whenever the use of a diuretic is considered. This is in order to prevent optimally the development of cardiovascular complications and the occurrence of metabolic side effects, in particular diabetes.

    Full Text Available Introduction. Several diagnostic tests have been recommended for risk assessment in pulmonary hypertension (PH, but the role of electrocardiography (ECG in monitoring of PH patients has not been yet established. Therefore the aim of the study was to evaluate which ECG patterns characteristic for pulmonary hypertension can predict hemodynamic improvement in patients treated with targeted therapies. Methods. Consecutive patients with pulmonary arterial hypertension (PAH or chronic thromboembolic pulmonary hypertension (CTEPH were eligible to be included if they had had performed two consecutive right heart catheterization (RHC procedures before and after starting of targeted therapies. Patients were followed up from June 2009 to July 2017. ECG patterns of right ventricular hypertrophy according to American College of Cardiology Foundation were assessed. Results. We enrolled 80 patients with PAH and 11 patients with inoperable CTEPH. The follow-up RHC was performed within 12.6±10.0 months after starting therapy. Based on median change of pulmonary vascular resistance, we divided our patients into two subgroups: with and without significant hemodynamic improvement. RV1, max⁡RV1,2 + max⁡SI,aVL-SV1, and PII improved along with the improvement of hemodynamic parameters including PVR. They predicted hemodynamic improvement with similarly good accuracy as shown in ROC analysis: RV1 (AUC: 0.75; 95% CI: 0.63–0.84, PII (AUC: 0.67, 95% CI: 0.56–0.77, and max⁡RV1,2+max⁡SI,aVL-SV1 (0.73; 95% CI: 0.63–0.82. In Cox regression only change in RV1 remained significant mortality predictor (HR: 1.12, 95% CI: 1.01–1.24. Conclusion. Electrocardiogram may be useful in predicting hemodynamic effects of targeted therapy in precapillary pulmonary hypertension. Decrease of RV1, max⁡RV1,2+max⁡SI,aVL-SV1, and PII corresponds with hemodynamic improvement after treatment. Of these changes a decrease of R wave amplitude in V1 is associated with better

    The purpose of this review is to discuss dyslipidemia in the various common clinical conditions including hypertension, diabetes mellitus, and metabolic syndrome and review the current therapeutic strategy in these settings. Dyslipidemias are common in patients with hypertension, diabetes mellitus, and metabolic syndrome. Epidemiologic studies have shown a strong correlation between serum lipid levels and risk of atherosclerotic cardiovascular disease. Multifactorial intervention strategies aimed at controlling lipids, blood pressure, and blood glucose simultaneously achieve maximal reductions in cardiovascular risk. Dyslipidemia and metabolic abnormalities are strongly associated with atherosclerosis and worse cardiovascular outcomes. While pharmacotherapy with statins has been proven to be beneficial for dyslipidemia, lifestyle modification emphasizing weight loss and regular exercise is an essential component of the interventional strategy. The common thread underlying atherosclerosis and metabolic abnormalities is endothelial dysfunction. Improved understanding of the role of endothelium in health and disease can potentially lead to novel therapies that may preempt development of atherosclerosis and its complications.

    Background & Aims Little is known about the prevalence and severity of portal hypertension in patients with non-alcoholic fatty liver disease (NAFLD). We investigated the prevalence and non-invasive predictors of portal hypertension in patients with NAFLD. Methods Signs of portal hypertension, including esophageal varices, splenomegaly, portosystemic encephalopathy, and ascites where investigated in 354 patients with NAFLD. Results One-hundred patients had portal hypertension at the time of NAFLD diagnosis (28.2%), 88 of these with septal fibrosis or cirrhosis (88%). Fibrosis stage correlated with presence (r=0.41, Pportal hypertension. Of the 204 patients with no or mild fibrosis (stages 0–2), 12 had portal hypertension (6%); they had a significantly higher grade of steatosis, based on biopsy analysis, compared to the 192 patients without portal hypertension (94%). Thrombocytopenia, hyperbilirubinemia, cirrhosis, and obesity were independently associated with portal hypertension. Esophageal varices were found in 57 of the 128 patients undergoing endoscopic screening (44.5%) and independently associated with thrombocytopenia, type 2 diabetes, and splenomegaly. Conclusions Signs of portal hypertension are present in 25% of patients at the time of diagnosis of NAFLD; most had advanced fibrosis or cirrhosis. Portal hypertension can occur in a small proportion of patients with mild or no fibrosis and is associated with the extent of steatosis. Features of advanced liver disease and insulin resistance might identify patients with NAFLD and portal hypertension, and those expected to derive the most benefit from endoscopic screening for esophageal varices.

    Full Text Available Pulmonary hypertension is a major reason for elevated perioperative morbidity and mortality, even in noncardiac surgical procedures. Patients should be thoroughly prepared for the intervention and allowed plenty of time for consideration. All specialty units involved in treatment should play a role in these preparations. After selecting each of the suitable individual anesthetic and surgical procedures, intraoperative management should focus on avoiding all circumstances that could contribute to exacerbating pulmonary hypertension (hypoxemia, hypercapnia, acidosis, hypothermia, hypervolemia, and insufficient anesthesia and analgesia. Due to possible induction of hypotonic blood circulation, intravenous vasodilators (milrinone, dobutamine, prostacyclin, Na-nitroprusside, and nitroglycerine should be administered with the greatest care. A method of treating elevations in pulmonary pressure with selective pulmonary vasodilation by inhalation should be available intraoperatively (iloprost, nitrogen monoxide, prostacyclin, and milrinone in addition to invasive hemodynamic monitoring. During the postoperative phase, patients must be monitored continuously and receive sufficient analgesic therapy over an adequate period of time. All in all, perioperative management of patients with pulmonary hypertension presents an interdisciplinary challenge that requires the adequate involvement of anesthetists, surgeons, pulmonologists, and cardiologists alike.

    This study aimed to determine the prevalence, determinants and pattern of herbal medicine use among hypertensive patients in Freetown. We conducted a cross-sectional study among hypertensive patients attending public and private health facilities in Freetown, Sierra Leone between August and October 2016. We analyzed the data using SPSS version 24. We used Chi-square, Fisher exact two-tailed test and regression analysis for data analysis. A p-value less than 0.05 was considered statistically significant. Out of 260 study participants, over half (n = 148, 56.9%) reported using herbal medicine for the treatment of hypertension alone or together with comorbid condition(s). The most commonly used herbal medicine among users were honey (n = 89, 33.3%), moringa (n = 80, 30.0%) and garlic (n = 73, 27.3%). No significant difference existed between users and non-users of herbal medicine with regards to socio-demographic and health-related factors. The majority (n = 241, 92.7%) of respondents considered herbal medicine beneficial if it was recommended by a healthcare provider yet 85.1% (n = 126) did not disclose their herbal medicine use to their health care provider. There is a high use of herbal medicines among hypertensive patients in Freetown, Sierra Leone. It is essential for healthcare providers to take heed of the findings of this study and routinely ask their patients about their herbal medicine use status. Such practice will provide the opportunity to discuss the benefits and risks of herbal medicine use with the aim of maximizing patient desired therapeutic outcomes. Copyright © 2018 Elsevier Ltd.

    Portal hypertension is one of the death reasons for the liver cirrhosis patients. The oxidative stress is related to the occurrence and development of portal hypertension in cirrhosis. Malondialdehyde (MDA), one of the lipid peroxides, increases substantially in cirrhotic patients. To evaluate the relevance between the MDA level and portal hypertension in cirrhotic patients. 60 liver cirrhotic patients and 30 healthy controls were enrolled. The plasma MDA level and general blood tests including ALT, AST, ALB, total bilirubin, and platelet were measured. All people enrolled accepted endoscopic examination and B-Ultrasound check to evaluate the severity of portal hypertension. The MDA plasma level of cirrhotic patients was significantly higher than the controls (Pportal hypertension (Pportal vein (r=0.652, Pportal hypertension. Plasma MDA level may correlate with the severity of portal hypertension in cirrhotic patients.

    For many years, it has been recognized that hypertension tends to cluster with various anthropometric and metabolic abnormalities including abdominal obesity, elevated triglycerides, reduced high-density lipoprotein cholesterol, glucose intolerance, insulin resistance and hyperuricemia. This constellation of various conditions has been transformed from a pathophysiological concept to a clinical entity, which has been defined metabolic syndrome (MetS). The consequences of the MetS have been difficult to assess without commonly accepted criteria to diagnose it. For this reason, on 2009 the International Diabetes Federation, the American Heart Association and other scientific organizations proposed a unified MetS definition. The incidence of the MetS has been increasing worldwide in parallel with an increase in overweight and obesity. The epidemic proportion reached by the MetS represents a major public health challenge, because several lines of evidence showed that the MetS, even without type 2 diabetes, confers an increased risk of cardiovascular morbidity and mortality in different populations including also hypertensive patients. It is likely that the enhanced cardiovascular risk associated with MetS in patients with high blood pressure may be largely mediated through an increased prevalence of preclinical cardiovascular and renal changes, such as left ventricular hypertrophy, early carotid atherosclerosis, impaired aortic elasticity, hypertensive retinopathy and microalbuminuria. Indeed, many reports support this notion, showing that hypertensive patients with MetS exhibit, more often than those without it, these early signs of end organ damage, most of which are recognized as significant independent predictors of adverse cardiovascular outcomes.

    To analyze the risk factors from radiological indices for hemorrhage in the patients with portal hypertension and weight risk factors. We retrospectively analyzed all cases of portal hypertension with hepatitis B from June 2008 to June 2014 in Nanjing Drum Tower hospital. Patients with hepatocellular carcinoma, portal vein thrombosis, or portal hypertension with other causes, such as autoimmune hepatitis, pancreatitis, or hematological diseases were excluded. Ninety-eight patients were recruited and divided into hemorrhage and non-hemorrhage groups. There were no statistical differences in clinical indexes such as age, prothrombin time, serum albumin, serum creatinine, serum sodium, hemameba, and blood platelet count. However, the differences were statistically significant in total bilirubin, hemoglobin, and liver function with the p values of 0.023, 0.000, and 0.039 respectively. For radiological indices, hemorrhage was correlated with diameter of inferior mesenteric vein (P=0.0528), posterior gastric vein (P=0.0283), and esophageal varices scores (P=0.0221). Logistic procedure was used to construct the model with stepwise selection and finally inferior mesenteric vein, posterior gastric vein, esophageal varices, and short gastric vein were enrolled into the model. These veins were scored according to the diameters and the rates of hemorrhage were increased with the score. We then validated the model with 26 patents from July 2014 to December 2014. The AUC value was 0.8849 in ROC curves for this radiological model. A risk model was constructed including inferior mesenteric vein, esophageal varices, posterior gastric vein, and short gastric vein. This radiological scoring model may be a valuable indicator for hemorrhage of portal hypertension.

    Practice guidelines advocate combining pharmacotherapy with lifestyle counseling for patients with hypertension. To allow for appropriate tailoring of interventions to meet individual patient needs, a comprehensive understanding of baseline patient characteristics is essential. However, few studies have empirically assessed behavioral profiles of hypertensive patients in Web-based lifestyle counseling programs. The objectives of this study were to (1) specify baseline psychobehavioral profiles of patients with hypertension who were enrolled in a Web-based lifestyle counseling trial, and (2) examine mean differences among the identified profile groups in demographics, psychological distress, self-reported self-care behaviors, physiological outcomes, and program engagement to determine prognostic implications. Participants (N=264; mean age 57.5 years; 154/264, 58.3% female; 193/264, 73.1% white) were recruited into a longitudinal, double-blind, randomized controlled trial, designed to evaluate an online lifestyle intervention for hypertensive patients. A series of latent profile analyses identified psychobehavioral profiles, indicated by baseline measures of mood, motivation, and health behaviors. Mean differences between profile groups were then explored. A 2-class solution provided the best model fit (the Bayesian information criterion (BIC) is 10,133.11; sample-size adjusted BIC is 10,006.54; Lo-Mendell-Rubin likelihood ratio test is 65.56, P=.001). The 2 profile groups were (1) adaptive adjustment, marked by low distress, high motivation, and somewhat satisfactory engagement in health behaviors and (2) affectively distressed, marked by clinically significant distress. At baseline, on average, affectively distressed patients had lower income, higher body mass index, and endorsed higher stress compared with their adaptive adjustment counterparts. At 12-months post intervention, treatment effects were sustained for systolic blood pressure and Framingham risk index

    The risk of major complications, especially hemorrhage, is significantly elevated during surgery in hypertensive patients. To determine whether percutaneous nephrolithotomy (PCNL) can be safely performed in the hypertensive patients using different sized instruments. We reviewed the records of 602 patients undergoing PCNL at our institution and identified 53 who were on antihypertensive therapy at the time of surgery. Patients were categorized into three groups according to size of devices used in surgery : those 24 F percutaneous tract with 22 F nephroscope (Group 1, n = 12 [22.7%]; 26 F percutaneous tract with 24 F nephroscope (Group 2, n = 19 [35.8%]) and 30 F percutaneous tract with 26 F nephroscope (Group 3, n = 22 [41.5%]). We compared the groups with regard to baseline characteristics, intraoperative parameters, stone-free and complication rates, and the length of hospitalization. There were no differences between the three groups in age, gender, weight and stone laterality. Fluoroscopy time, access to the collecting system and mean operative time for per cm2 stone did not differ between the groups. Hemoglobin decrease, postoperative hospital stay and blood transfusion rate was higher in group 3. Stones were completely cleared in 83.3%, 84.2% and 81.3% of patients, which increased to 91.6%, 89.5%, and 90.1% with adjunctive therapy in the group 1,2 and 3, respectively. PCNL with smaller devices is a safe and effective method in hypertensive patients. It has significantly a shorter hospital stay and less bleeding rates compared to classical PCNL.

    Full Text Available OBJECTIVE: Cardiovascular risk increases with the presence of both metabolic syndrome (MetS and hypertension (HTN. Although the adiponectin (ADIPOQ gene has been reported to be involved in MetS, its association with HTN remained undetermined. This study aimed to investigate the association of ADIPOQ gene with the phenotypes of HTN and MetS. METHODS: A total of 962 participants from 302 families from the Taiwan young-onset hypertension genetic study were enrolled. Plasma adiponectin were measured, and association analysis was conducted by using GEE regression-based method. Another study, of 1448 unrelated participants, was conducted to replicate the association between ADIPOQ gene and variable phenotypes of MetS with or without HTN. RESULTS: Among 962 subjects from family samples, the lowest plasma adiponectin value was observed in MetS with HTN component (9.3±0.47 µg/ml compared with hypertensives (13.4±0.74 µg /ml or MetS without HTN (11.9±0.60 µg/ml, P<0.05. The SNP rs1501299 (G276T in ADIPOQ gene was found associated with the presence of HTN in MetS (odds ratio for GG+GT vs. TT = 2.46; 95% CI: 1.14-5.3, p = 0.02, but not rs2241766 (T45G. No association of ADIPOQ gene with HTN alone or MetS without HTN was observed. The significant association of the SNP rs1501299 (G276T with the phenotype of presence of HTN in MetS was confirmed (odds ratio for GG+GT vs. TT = 2.15; 95% CI: 1.1-4.3 in the replication study. CONCLUSIONS: ADIPOQ genetic variants were selectively and specifically associated with the concomitant presence of MetS and HTN, suggesting potential genetic linkage between MetS and HTN.

    Exercise radionuclide ventriculography (ERV) is considered a superior non-invasive screening test for coronary artery disease (CAD). ERV showed, however, a low specificity in hypertensive patients (H). The diagnostic accuracy of EAR and thallium-201 myocardial scintigraphy (M) was evaluated in 23 patients (H) with chest pain and positive ECG-strees test. All patients underwent ERV and M, randomly, in different days. Finally, they all underwent coronary angiography: CAD was diagnosed in case of luminal narrowing ≥ 70% in 1 major coronary artery at least. Eleven patients had severe CAD. ERV was considered positive for CAD in presence of ex-induced abnormality of wall motion and/or in case of ex-induced ejection fraction increase ≤ 5% respect to the basal values. M was considered positive for CAD when perfusion defects were observed in early images only. ERV showed low diagnostic accuracy. On the contrary M had both sensibility and specificity, and a high positive and negative predictive value in the diagnosis of CAD. M is thus suggested as the non-invasive methodology of choice in hypertensive patients with suspected CAD

    Essential hypertension (HTN) is a multifactorial disease involving environmental, genetic and other factors. Over the past years, genetic studies of essential HTN have increased dramatically but the molecular mechanisms involved are still unknown. As part of a research program coordinated by Boston university (USA), we studied the role of various genes and single nucleotide polymorphisms (SNPs) in the inheritance or the onset of HTN in African-American, Caucasian-American and Greek families. Among 128 Greek families with a history of HTN, we studied 1474 people. Of the total examined, 273 men and 286 women were hypertensive. Based on 410 DNA samples from the hypertensive subjects, different SNPs were examined. An overall meta-analysis of the results from the Greek families, as well as a comparison with the 2 other groups (African-Americans and Caucasian-Americans), was performed. We report SNPs that are associated with the inheritance of HTN and are located either at the promoters of N-methyltransferase and catalase genes, or within the coding region of NEDD4L ubiquitin ligase gene, or SNPs in mitochondrial DNA of hypertensive probands. Furthermore, we clarified the role of hereditary predisposition in the development of HTN, showing that the presence of maternal HTN was significantly higher in African-Americans and Greeks compared to Caucasian-Americans (81.7%, 84.8%, and 65%), while the paternal HTN showed no such difference (50%, 48.3% and 44.9%), respectively. Although genetic factors that were correlated with HTN were identified, it was not possible to identify a single gene that should be targeted for the treatment of HTN. Nevertheless, the important role of the maternal hereditary predisposition to HTN in the Greek patients and the responsible genetic factors involved should be further examined.

    rates were evaluated in all subjects by means of a gamma camera technique. The technique was also used to measure the frequency of antral contractions. RESULTS: No difference was observed in gastric mean emptying time or small-intestinal mean transit time of liquid and solid markers between patients...... and controls. After 24 h, however, the geometric center of the liquid marker had a more caudal localization in the colon of the patient group than in the controls (P = 0.04); that is, the patients had a faster colonic transit. No difference was found in the frequency of antral contractions 45 min after...... the test meal between patients and controls. CONCLUSIONS: These data suggest that the colonic transit is often accelerated in patients with portal hypertension, whereas the motor function of the stomach and the small intestine is unaffected....

    Patients with hypertension are primarily treated in general practice. However, major studies of patients with hypertension are rarely based on populations from primary care. Knowledge of blood pressure (BP) control rates in patients with diabetes and/or cardiovascular diseases (CVDs), who have...... additional comorbidities, is lacking. We aimed to investigate the association of comorbidities with BP control using a large cohort of hypertensive patients from primary care practices....

    The literature about possible cardiovascular consequences of diagnostic inertia in diabetes is scarce. We examined the influence of undetected high fasting blood glucose (FBG) levels on the cardiovascular risk and poor control of cardiovascular risk factors in hypertensive or obese patients, with no previous diagnosis of diabetes mellitus (i.e., diagnostic inertia). A cross-sectional study during a preventive program in a Spanish region was performed in 2003-2004. The participants were aged ≥40 years and did not have diabetes but were hypertensive (n = 5, 347) or obese (n = 7, 833). The outcomes were high cardiovascular risk (SCORE ≥5%), poor control of the blood pressure (≥140/90 mmHg) and class II obesity. The relationship was examined between FBG and the main parameters, calculating the adjusted odd ratios with multivariate models. Higher values of FBG were associated with all the outcomes. A more proactive attitude towards the diagnosis of diabetes mellitus in the hypertensive and obese population should be adopted.

    Full Text Available Transient global amnesia was established by Fisher et Adams is 1964 for phenomena characterized by the sudden onset of all types memory loss, retrograde amnesia and the inability to form new  memories and to recall the recent past. The incidence of TGA is 5  to10 people per 100,000 worldwide but the real incidence is unknown because the episodes of memory loss are temporary and many patients don’t go to see a doctor at the time of attack. The triggers of TAG are physical activity, sexual  intercourse, pain, Valsalva maneuver etc. In routine clinical practice  TAG is more important for neurologists. But this problem is also  interesting for therapeutists because TAG could be developed in  patients with arterial hypertension, foramen ovale, mitral valve  prolapse and heart blocks. We present a 57-year-old female with  TAG. She was admitted to the hospital due to hypertensive crisis and an impaired ability to retain new information that started after  physical activity. The diagnosis of TAG was based on information  from attacks witnesses, the sudden onset of anterograde amnesia,  normal cognition of the patient and short duration of attack. Also,  the patient had no features of stroke, acute hypertensive encephalopathy, epilepsy and alcohol blackout. TAG is more typical for females over 50 years, all symptoms start after physical activity and resolve within 24 hours. It is characterized by reversibility of all symptoms and good prognosis of 2 years of follow-up.

    Objective: Whether elevated cTnI is associated with cardiovascular or cerebrovascular events in patients with hypertension (HT) without left ventricular(LV) systolic dysfunction is not clear. Method: We measured cTnI serum level in 170 patients with essential HT without LV systolic dysfunction (LVEF 55%),renal failure,and prior cardiovascular or cerebrovascular diseases. Besides, control group of 40 normal presons was established and following up (45±38)months. Results: Level of cTnI was elevated (≥0.04 ng/ml) in 15 (8.8%) of the 170 patients and in 0 (0%) of the 40 normal controls. The rate of diabetes mellitus(DM), the cardiothoracic ratio, serum NT-proBNP value, and LV mass index were significantly higher in patients with than without elevated cTnI (DM, 9/15 versus 25/155, P 2 , P=0.0001). Kaplan-Meier analysis demonstrated that significantly fewer (P<0.000001) patients with, than without elevated cTnI remained free of events (hospitalization due to cardiovascular or cerebrovascular disease). Stepwise Cox multivariate analysis revealed that elevated cTnT (hazard ratio, 6.59, P=0.000001) and smoking (hazard ratio, 2.26, P=0.04) were independent predictors of events. Conclusion: The present findings indicate that cTnI is a biomarker and useful predictor of future cardiovascular or cerebrovascular events in hypertensive patients. (authors)

    The impact of antihypertensive treatment on blood pressure (BP) control is fairly unknown. The aim of the study was to evaluate the degree of BP control and its relationship with treatment-related factors in hypertensive patients treated with 2 or 3 agents and attended in referral units. We studied 1,337 hypertensive subjects (41% women) with a mean age (SD) of 63 (12) years, who were receiving 2 or 3 antihypertensive drugs. The degree of BP control was estimated in a single visit by the proportion of patients with BP below 140/90mmHg. BP was controlled in 767 patients (57%). Lack of BP control was related to older age (12% risk for each 10-year increase) and the presence of microalbuminuria (64% risk increase). In those treated with 2 agents, BP control was 61%, without differences between those treated with fixed-drug or free combinations. BP control in those treated with 3 agents was 55%, higher in those receiving 3 agents in a fixed-drug combination (68%) compared with those on 3 agents administered separately (52%; P=.025). Drug classes used in combinations did not influence the degree of BP control. The degree of BP control in patients treated with 2 or 3 agents is 57%. Microalbuminuria is related to a lack of BP control. In those receiving 3 agents, the use of fixed-drug combinations is associated with better BP control. Copyright © 2013 Elsevier España, S.L.U.

    Full Text Available OBJECTIVE: To evaluate the role of right heart catheterization in the diagnosis of pulmonary arterial hypertension (PAH. METHODS: We evaluated clinical, functional, and hemodynamic data from all patients who underwent right heart catheterization because of diagnostic suspicion of PAH-in the absence of severe left ventricular dysfunction (LVD, significant changes in pulmonary function tests, and ventilation/perfusion lung scintigraphy findings consistent with chronic pulmonary thromboembolism-between 2008 and 2013 at our facility. RESULTS: During the study period, 384 patients underwent diagnostic cardiac catheterization at our facility. Pulmonary hypertension (PH was confirmed in 302 patients (78.6%. The mean age of those patients was 48.7 years. The patients without PH showed better hemodynamic profiles and lower levels of B-type natriuretic peptide. Nevertheless, 13.8% of the patients without PH were categorized as New York Heart Association functional class III or IV. Of the 218 patients who met the inclusion criteria, 40 (18.3% and 178 (81.7% were diagnosed with PH associated with LVD (PH-LVD and with PAH, respectively. The patients in the HP-LVD group were significantly older than were those in the PAH group (p < 0.0001. CONCLUSIONS: The proportional difference between the PAH and PH-LVD groups was quite significant, considering the absence of echocardiographic signs suggestive of severe LVD during the pre-catheterization investigation. Our results highlight the fundamental role of cardiac catheterization in the diagnosis of PAH, especially in older patients, in whom the prevalence of LVD that has gone undiagnosed by non-invasive tests is particularly relevant.

    Hypertension constitutes a major health problem and the challenge is to identify patients having 'surgically' curable renal vascular disease among the majority with so-called essential hypertension. The best of unsatisfactory diagnostic tests are renography and plasma renin activity both before and during angiotensin II blockade. The necessity of better screening tests has increased because of the recent advances in surgical techniques and especially percutaneous transluminal renal angioplasty. The latter has definitely become the method of choice for correction of suspected hemodynamically significant artery stenoses whenever technically feasible. With improved angioplasty techniques the risk of treating renal artery stenosis without hemodynamic and clinical importance (so-called cosmetic repair) has increased. Unfortunately randomized trials including surgery versus angioplasty are not available. It should be kept in mind that only after correction of the stenosis is achieved and the blood pressure has become normal, can the diagnosis of renovascular hypertension be made with certainty.

    The aim of this study was to evaluate the use of spironolactone and doxazosin as treatment for patients with resistant hypertension. This retrospective study involved 181 outpatients with resistant hypertension (defined as a failure of blood pressure [BP] control despite treatment with three drugs, one of which was a diuretic) who received additional spironolactone (n=88) or doxazosin (n=93). Mean systolic BP in the spironolactone group fell by 28 mmHg (95% confidence interval [CI], 24-32 mmHg; P< .001) and mean diastolic BP fell by 12 mmHg (95% CI, 9-14 mmHg; P< .001). The corresponding falls in the doxazosin group were 16 mmHg (95% CI, 13-20 mmHg; P< .001) and 7 mmHg (95% CI, 5-9 mmHg; P< .001), respectively. The decrease was significantly greater with spironolactone for both systolic (P< .001) and diastolic (P=.003) pressures. At the end of follow-up, 30% of all patients had achieved BP control, with control being more frequent with spironolactone (39%) than doxazosin (23%; P=.02). Multivariate logistic regression analysis showed that the only factors that significantly influenced the achievement of BP control were diabetes (odds ratio=0.17; 95% CI, 0.08-0.39; P< .001) and baseline systolic BP <165 mmHg (odds ratio=2.56; 95% CI, 1.11-5.90; P=.03). In patients with resistant hypertension, the addition of either spironolactone or doxazosin resulted in a significant decrease in BP, though the decrease appeared to be greater with spironolactone. The presence of diabetes complicated BP control.

    Calcification of the walls of the veins of the portal hypertension (PHT) (1-0), is uncommon. Calcification of the intra splenic vessels is exceptional. We report two cases of isolated calcification of intra splenic vessels, without calcification of the splenoportal venous axis, in patients with liver cirrhosis and PHT. The calcification was not clear. Computed tomography identified the calcification as linear tubular, branched structures located in the wall of intra splenic vessels. magnetic resonance imaging disclosed signs of cirrhosis and PHT but did not show the splenic classifications because of technical limitations. The cause of these calcifications was sustained PHT due to chronic liver disease. (Author) 15 refs

    Treatment of acute emergencies in patients with pulmonary arterial hypertension (PAH) can be challenging. In the UK and Ireland, management of adult patients with PAH is centred in eight nationally designated pulmonary hypertension (PH) centres. However, many patients live far from these centres and physicians in local hospitals are often required to manage PAH emergencies. A committee of physicians from nationally designated PH centres identified the 'most common' emergency clinical scenarios encountered in patients with PAH. Thereafter, a review of the literature was performed centred on these specified topics and a management approach was developed based on best available evidence and expert consensus. Management protocols were developed on the following PAH emergencies: chest pain (including myocardial ischaemia), right ventricular failure, arrhythmias, sepsis, haemoptysis ('CRASH'), as well as considerations relevant to surgery, anaesthesia and pregnancy. Emergencies are not uncommon in PAH. While expertise in PAH management is essential, all physicians involved in acute care should be aware of the principles of acute management of PAH emergencies. A multidisciplinary approach is necessary, with physicians from tertiary PH centres supporting care locally and planning safe transfer of patients to PH centres when appropriate. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Hypertension is related with cognitive decline in the elderly. The frontal-parietal executive system plays an important role in cognitive aging and is also vulnerable to damage in elderly patients with hypertension. Examination of the brain's functional characteristics in frontal-parietal regions of hypertension is likely to be important for understanding the neural mechanisms of hypertension's effect on cognitive aging. We address this issue by comparing hypertension and control-performers in a functional MRI study. Twenty-eight hypertensive patients and 32 elderly controls were tested with n-back task with two load levels. The hypertensive patients exhibited worse executive and memory abilities than control subjects. The patterns of brain activation changed under different working memory loads in the hypertensive patients, who exhibited reduced activation only in the precentral gyrus under low loads and reduced activation in the middle frontal gyrus, left medial superior frontal gyrus and right precuneus under high loads. Thus, more regions of diminished activation were observed in the frontal and parietal regions with increasing task difficulty. More importantly, we found that lower activation in changed frontal and parietal regions was associated with worse cognitive function in high loads. The results demonstrate the relationship between cognitive function and frontoparietal functional activation in hypertension and their relevance to cognitive aging risk. Our findings provide a better understanding of the mechanism of cognitive decline in hypertension and highlight the importance of brain protection in hypertension.

    To evaluate the influence of serum Lp(a) concentration on hypertension in patients with diabetes mellitus (DM) and under treatment with oral hypoglycemic agents or insulin injections, we studied 122 patients, 82 females and 40 males with a mean age of 63+-10 years and duration of DM and HTN of 7.4+-5.8 and 3.2+-4.6 years, respectively. The mean systolic and diastolic blood pressure (BP) was 138+-23 mmHg and 83+-12mmHg, respectively. In this cross-sectional study, we measured serum lipoprotein (a) (Lp(a), glycosilated hemoglobin (HbA1c) and other lipids while the patients were receiving either oral hypoglycemic agents or insulin. In addition, body mass index (BMI) and creatinine clearance (CrCL) were assessed. The mean serum Lp(a) was 22.2+-24.7 mg/dl (median: 18.3 mg/dl), and serum Lp(a) levels >30 mg/dl was found in 29(23.8%) patients. There were significant positive correlations of duration of DM and duration of hypertension, and serum Lp(a) levels with of systoli and diastolic levels of BP. However, a significant inverse correlation of serum Lp(a) with CrCl were observed. This study suggests that kidney function is an independent determination of Lp(a) and HTN in diabetic patients. Furthermore Lp(a) in diabetic patients may have important implications for the increased susceptibility to vascular diseases in these patients. (author)

    Full Text Available BackgroundMany studies have aimed to determine whether body mass index (BMI, waist circumference (WC, or waist to hip ratio (WHR best predicts hypertension in diabetic patients, with conflicting results. However, no study has examined the specific relationship between these anthropometric parameters with sustained normotension (SNT, white coat hypertension (WCHT, masked hypertension (MHT, and sustained hypertension (SHT based on office and ambulatory blood pressure (BP measurements in these patients.MethodsPatients with newly diagnosed type 2 diabetes underwent the following procedures: history taking, measurements of anthropometric parameters, office and ambulatory BP measurements, physical examination, laboratory analysis, and random and 24-hour urine analysis.ResultsIn total, there were 65 dippers and 37 nondipper patients. None of the anthropometric parameters were different between the dippers and the nondippers. There were 25 patients with SNT, 32 with WCHT, seven with MHT, and 38 with SHT. A comparison of anthropometric parameters between these four groups of patients showed that WC (P=0.016 and WHR (P=0.015 were different among all groups. According to regression analysis, only BMI was independently related with MHT (odds ratio [OR], 1.373, P=0.022, whereas only WC has been associated with SHT (OR, 1.321, P=0.041.ConclusionAmong anthropometric parameters, only WC and WHR were different in SNT, WCHT, MHT, and SHT in newly diagnosed patients with type 2 diabetes.

    2015-06-01

    Addison's disease may be complicated by hypertension and less commonly by heart failure. We review the pathophysiology of the renin-angiotensin-aldosterone axis in Addison's disease and how this is altered in the setting of hypertension and heart failure. An essential first step in management in both conditions is optimizing glucocorticoid replacement and considering dose reduction if excessive. Following this, if a patient with Addison's disease remains hypertensive, the fludrocortisone dose should be reviewed and reduced if there are clinical and/or biochemical signs of mineralocorticoid excess. In the absence of such signs, where the renin is towards the upper end of the normal range or elevated, an angiotensin II (AII) receptor antagonist or angiotensin converting enzyme (ACE) inhibitor is the treatment of choice, and the fludrocortisone dose should remain unchanged. Dihydropyridine calcium channel blockers are clinically useful as second line agents, but diuretics should be avoided. In the setting of heart failure, there is an increase in total body sodium and water; therefore, it is appropriate to reduce and rarely consider ceasing the fludrocortisone. Loop diuretics may be used, but not aldosterone antagonists such as spironolactone or eplerenone. Standard treatment with ACE inhibitors, or as an alternative, AII receptor antagonists, are appropriate. Measurements of renin are no longer helpful in heart failure to determine the volume status but plasma levels of brain natriuretic peptide (BNP/proBNP) may help guide therapy. © 2014 John Wiley & Sons Ltd.

    The ventilation-perfusion scans of 30 patients with pulmonary arterial hypertension and established final diagnoses were blindly classified as to the probability of showing pulmonary embolism. Eleven of 12 patients with primary pulmonary hypertension had normal or low-probability scans; one had an intermediate-probability scan. All six patients with thromboembolic pulmonary hypertension had high-probability scans. However, three of 12 patients with nonembolic secondary pulmonary hypetension also had high-probability scans. Although a normal or low-probability scan excludes the possibility of emboli as a cause, a high-probability scan may often be associated with nonembolic causes of secondary pulmonary hypertension

    To determine the diagnostic impact of MR imaging in pulmonary hypertension (PH), the authors have examined 12 PH patients with a 0.5- or 1.5-T magnet in a double-angulation projection with multisection, multiphase technique and a gradient-echo sequence. MR data were evaluated for right ventricular volumes or function and compared with data from 10 control subjects. In PH patients, MR imaging showed right ventricular enlargement with hypertrophy, right atrial enlargement, and abnormal septal motion. Right ventricular (RV) function was compromised, with reduced RV circumferential shortening. PH patients had a severe reduction of long-axis shortening and variable reduction of short-axis shortening that correlated with the degree of PH (r = .68, P <.01)

    Radioisotopic splenoportography (RI-splenoportography) was performed in 11 children (6 patients with biliary atresia, 3 with extrahepatic portal obstruction, 1 with congenital hepatic fibrosis and 1 with pediatric liver cirrhosis). Collateral pathways were found in 9 patients by RI-imaging, of whom 6 patients had ascending pathways alone, 1 had both ascending and descending pathways, and 2 had only descending pathways. Esophageal varices were found endoscopically in all 7 patients with ascending collateral pathways, but were not found in 2 patients with the descending collateral pathways alone or in 2 patients without collateral pathway images. Endoscopic injection sclerotherapy (EST) was performed in one patient with biliary atresia who had had episodes of rupture of esophageal varices. Ascending collateral pathways were recognized by RI-splenoportography before EST, but they disappeared completely after three sessions of EST. In two patients with extrahepatic portal obstruction and a patient with congenital hepatic fibrosis who underwent meso-caval shunt operations, shunt patency and disappearance of ascending collateral pathways were proved clearly by RI-splenoportography after the operations. RI-splenoportography is very useful for investigation of portal venous collateral circulation in portal hypertension or for confirming patency of portosystemic shunts. (author)

    Purpose: To evaluate the effectiveness of partial splenic embolization (PSE) in patients with idiopathic portal hypertension (IPH) in reducing variceal bleeding episodes, splenomegaly and thrombocytopenia. Materials and methods: Six patients (2M, 4F, mean age 30.3 years) with IPH presenting with splenomegaly, thrombocytopenia and recurrent variceal bleeding were treated with PSE using gelatin sponge (four patients) or Contour particles (two patients) as embolization material. Results: PSE was performed successfully in all cases; 3F coaxial microcatheters were necessary in two patients due to extreme splenic artery tortuosity. The average amount of devascularized parenchyma at CT 1 week after PSE was 71%. Splenomegaly and thrombocytopenia improved in all cases, with a mean platelet count increase of 120000/mm{sup 3} and an average 68% reduction of spleen volume at follow up. Variceal bleeding did not recur after PSE. Esophageal or gastroesophageal varices disappeared (one patient) or significantly reduced (five patients) at endoscopic controls. No significant complications were noted. The follow up was of at least 18 months in all patients; mean follow up was 28.2 months. Conclusion: In patients with IPH PSE can be effective in preventing variceal bleedings, in reducing spleen volume and in significantly increasing platelet count; therapeutic results were durable in our population.

    Full Text Available Anne M Keogh, Andrew Jabbour, Christopher S Hayward, Peter S MacdonaldHeart Lung Transplant Unit, St Vincent’s Hospital, Sydney, New South Wales, AustraliaAbstract: Sildenafil is a selective inhibitor of phosphodiesterase type 5 (PDE-5. Its chronic administration has been shown to improve exercise capacity, World Health Organization functional class, and haemodynamics in patients with symptomatic pulmonary arterial hypertension (PAH. There is however, no data describing the clinical consequences of sudden cessation of sildenafil treatment. In this series, 9 patients with NYHA Class II–IV PAH who were stable on 2 months of sildenafil monotherapy, had their sildenafil ceased to accommodate a 2-week washout period, required for enrollment in research involving an endothelin receptor antagonist. Six minute walk distance (SMWD and clinical assessments were performed before cessation of sildenafil, and again 2 weeks later. Over the course of this 2-week washout period, 6 of the 9 patients reported increased breathlessness and fatigue, 1 of these was hospitalized with worsening right heart failure. The SMWD fell in 6 patients, with falls of greater than 100 m recorded in 4 patients. This was accompanied by a worsening of NYHA Class from 2.5 ± 0.2 to 3.1 ± 0.1 (mean ± SEM, p = 0.01. These data indicate that sudden cessation of sildenafil monotherapy, in patients with PAH, carries with it a significant and unpredictable risk of rapid clinical deterioration. We recommend that if sildenafil needs to be ceased, it would be more prudent to consider concurrent vasodilator therapy before the gradual cessation of sildenafil.Keywords: sildenafil, pulmonary hypertension, phosphodiesterase inhibitor

    Full Text Available OBJECTIVE: To assess the effect of blood pressure (BP control and other cardiovascular risk factors in patients with diabetes mellitus in a referral service for the treatment of hypertension. METHODS: A retrospective study where diabetic patients (at least 2 fasting glucose levels above 126 mg/dL, use of hypoglycemic agents or insulin, or both of these were included. They were evaluated at the first appointment (M1 and at the last appointment (M2, regarding blood pressure, body mass index (BMI, use of hypertensive drugs, glycemia, total cholesterol (TC, creatinine, and potassium. RESULTS: Of 1,032 patients studied, 146 patients with a mean age of 61.6 years had diabetes, and 27 were men (18.5%. Mean follow-up was 5.5 years. BP values were 161.6 x 99.9 mmHg in M1 and 146.3 x 89.5 mmHg in M2. In M1, 10.4% of the patients did not use medications, 50.6% used just 1 drug, 30.8% used 2 drugs, and 8.2% used 3 or more drugs. In M2, these values were 10.9%, 39%, 39.7%, and 10.4%, respectively. Diuretics were the most commonly used medication, whereas angiotensin-converting enzyme inhibitors (ACE inhibitors were those drugs which presented greater increase when comparing M1 to M2 (24.6% and 41.7%, respectively. Only 17,1% reached the recommended goal (BP<130x85 mmhg. The other cardiovascular risk factors did not change significantly. CONCLUSION: Our data reinforce the necessity of a more aggressive approach in the treatment of these patients, despite the social and economic difficulties in adhering to treatment.

    Uncontrolled hypertension remains a significant problem for many patients. Few interventions to improve patients' hypertension self-management have had lasting effects. Previous work has focused largely on patients' beliefs as predictors of behavior, but little is understood about beliefs as they are embedded in patients' social contexts. This study aims to explore how patients' "explanatory models" of hypertension (understandings of the causes, mechanisms or pathophysiology, course of illness, symptoms and effects of treatment) and social context relate to their reported daily hypertension self-management behaviors. Semi-structured qualitative interviews with a diverse group of patients at two large urban Veterans Administration Medical centers. PARTICIPANTS (OR PATIENTS OR SUBJECTS): African-American, white and Latino Veterans Affairs (VA) primary care patients with uncontrolled blood pressure. We conducted thematic analysis using tools of grounded theory to identify key themes surrounding patients' explanatory models, social context and hypertension management behaviors. Patients' perceptions of the cause and course of hypertension, experiences of hypertension symptoms, and beliefs about the effectiveness of treatment were related to different hypertension self-management behaviors. Moreover, patients' daily-lived experiences, such as an isolated lifestyle, serious competing health problems, a lack of habits and routines, barriers to exercise and prioritizing lifestyle choices, also interfered with optimal hypertension self-management. Designing interventions to improve patients' hypertension self-management requires consideration of patients' explanatory models and their daily-lived experience. We propose a new conceptual model - the dynamic model of hypertension self-management behavior - which incorporates these key elements of patients' experiences.

    Full Text Available Aim. To evaluate the effect of metoprolol tartrate on blood pressure (BP and cognitive function in young to middle aged patients with essential hypertension (HT.Material and methods. 40 men (age of 49,0±1,9 y.o. with HT of I-II stage not taking antihypertensive medication regularly were enrolled into the study. All patients were given metoprolol tartrate (start dose 50-100 mg/d. Variables of 24-h BP monitoring and clinic BP, left ventricular mass index (measured by echocardiography and characteristics of cognitive function (memory, attention, thinking and neurodynamic were assessed at the start, after 1 and 6 months of therapy.Results. Good and satisfactory antihypertensive effect was achieved in 75% of hypertensive patients with metoprolol (186,6±13,4mg/d monotherapy. Metoprolol significantly decreased maximum day-time systolic and diastolic BP, maximum night-time diastolic BP, mean day-time systolic and night-time diastolic BP, time-index, load-index and variability-index for night-time diastolic BP, day-time and night-time pulse BP. Left ventricular mass index reduced significantly (p<0,0001. After 6 months of therapy significant improvement of memory, attention, thinking and neurodynamic was observedConclusion. Metoprolol had beneficial effect on cognitive function in hypertensive patients, which demonstrate its cerebroprotective properties in addition to antihypertensive action. Metoprolol can reduce the risk of dementia in young to middle aged patients with HT.

    Hypertension is a common disease and a crucial predisposing factor of cardiovascular diseases. Approximately 10% of hypertensive patients are secondary hypertension, a pathogenetic factor of which can be identified. Secondary hypertension consists of endocrine, renal, and other diseases. Primary aldosteronism, Cushing's syndrome, pheochromocytoma, hyperthyroidism, and hypothyroidism result in endocrine hypertension. Renal parenchymal hypertension and renovascular hypertension result in renal hypertension. Other diseases such as obstructive sleep apnea syndrome are also very prevalent in secondary hypertension. It is very crucial to find and treat secondary hypertension at earlier stages since most secondary hypertension is curable or can be dramatically improved by specific treatment. One should keep in mind that screening of secondary hypertension should be done at least once in a daily clinical practice.

    Background: Diabetic retinopathy is a common microvascular complication of both type 1 and type 2 diabetes mellitus. If left untreated, it can progress to serious visual disability. Coexistence of hypertension with diabetes has been described as another risk factor adding to the problem. We designed this study to assess the occurrence of diabetic retinopathy in hypertensive diabetic patients of this region and to compare it with normotensive diabetic patients. Methods: This cross-sectional study was carried out on 200 previously diagnosed diabetic patients. Apart from routine examination and investigations, retinopathy and
