Portal hypertension is a major pathophysiology in patients with cirrhosis. Portal pressure is the gold standard to evaluate the severity of portal hypertension, and radiological intervention is the only procedure for pressure measurement. Ultrasound (US) is a simple and noninvasive imaging modality available worldwide. B-mode imaging allows broad applications for patients to detect and characterize chronic liver diseases and focal hepatic lesions. The Doppler technique offers real-time observation of blood flow with qualitative and quantitative assessments, and the application of microbubble-based contrast agents has improved the detectability of peripheral blood flow. In addition, elastography for the liver and spleen covers a wider field beyond the original purpose of fibrosis assessment. These developments enhance the practical use of US in the evaluation of portal hemodynamic abnormalities. This article reviews the recent progress of US in the assessment of portal hypertension.

With increasing attention to renovascular causes and targets for hypertension there arises a critical need for more detailed knowledge of renal arterial anatomy. However, a standardised nomenclature is lacking. The present study sought to develop a standardised nomenclature for renal anatomy considering the complexity and variation of the renal arterial tree and to assess the applicability of the nomenclature. One thousand hypertensive patients underwent invasive selective renal artery angiography in nine centres. Further, renovasography was performed in 249 healthy swine as a surrogate for normotensive anatomy. Anatomical parameters were assessed by quantitative vascular analysis. Patients' mean blood pressure was 168/90±26/17 mmHg. The right main renal artery was longer than the left (41±15 mm vs. 35±13 mm, prenal arteries and renal artery disease were documented in 22% and 9% of the patients, respectively. Other than exhibiting a longer left main renal artery in uncontrolled hypertensives (+2.7 mm, p=0.034) there was no anatomical difference between patients with controlled and uncontrolled hypertension. Main renal artery mean diameter was smaller in patients with impaired kidney function (GFR Renal arterial anatomy differs between sides but shows no difference between patients with and without blood pressure control. Impaired GFR was associated with small main renal artery diameter.

Hypertension Canada's Canadian Hypertension Education Program Guidelines Task Force provides annually updated, evidence-based recommendations to guide the diagnosis, assessment, prevention, and treatment of hypertension. This year, we present 4 new recommendations, as well as revisions to 2 previous recommendations. In the diagnosis and assessment of hypertension, automated office blood pressure, taken without patient-health provider interaction, is now recommended as the preferred method of measuring in-office blood pressure. Also, although a serum lipid panel remains part of the routine laboratory testing for patients with hypertension, fasting and nonfasting collections are now considered acceptable. For individuals with secondary hypertension arising from primary hyperaldosteronism, adrenal vein sampling is recommended for those who are candidates for potential adrenalectomy. With respect to the treatment of hypertension, a new recommendation that has been added is for increasing dietary potassium to reduce blood pressure in those who are not at high risk for hyperkalemia. Furthermore, in selected high-risk patients, intensive blood pressure reduction to a target systolic blood pressure ≤ 120 mm Hg should be considered to decrease the risk of cardiovascular events. Finally, in hypertensive individuals with uncomplicated, stable angina pectoris, either a β-blocker or calcium channel blocker may be considered for initial therapy. The specific evidence and rationale underlying each of these recommendations are discussed. Hypertension Canada's Canadian Hypertension Education Program Guidelines Task Force will continue to provide annual updates. Copyright © 2016 Canadian Cardiovascular Society.

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.

2005-04-01

Full Text Available Abstract Background The effects of pulmonary arterial hypertension on brain function are not understood, despite patients' frequent complaints of cognitive difficulties. Using clinical instruments normally administered during standard in-person assessment of neurocognitive function in adults, we assembled a battery of tests designed for administration over the telephone. The purpose was to improve patient participation, facilitate repeated test administration, and reduce the cost of research on the neuropsychological consequences of acute and chronic cardiorespiratory diseases. We undertook this study to validate telephone administration of the tests. Methods 23 adults with pulmonary arterial hypertension underwent neurocognitive assessment using both standard in-person and telephone test administration, and the results of the two methods compared using interclass correlations. Results For most of the tests in the battery, scores from the telephone assessment correlated strongly with those obtained by in-person administration of the same tests. Interclass correlations between 0.5 and 0.8 were observed for tests that assessed attention, memory, concentration/working memory, reasoning, and language/crystallized intelligence (p ≤ 0.05 for each. Interclass correlations for the Hayling Sentence Completion test of executive function approached significance (p = 0.09. All telephone tests were completed within one hour. Conclusion Administration of this neurocognitive test battery by telephone should facilitate assessment of neuropsychological deficits among patients with pulmonary arterial hypertension living across broad geographical areas, and may be useful for monitoring changes in neurocognitive function in response to PAH-specific therapy or disease progression.

The gold standard to assess the presence and severity of portal hypertension remains the hepatic vein pressure gradient, however the recent development of non-invasive assessment using elastography techniques offers valuable alternatives. In this review, we discuss the diagnostic accuracy and utility of such techniques in patients with portal hypertension due to cirrhosis. Areas covered: A literature search focused on liver and spleen stiffness measurement with different elastographic techniques for the assessment of the presence and severity of portal hypertension and oesophageal varices in people with chronic liver disease. The combination of elastography with parameters such as platelet count and spleen size is also discussed. Expert commentary: Non-invasive assessment of liver fibrosis and portal hypertension is a validated tool for the diagnosis and follow-up of patients. Baveno VI recommended the combination of transient elastography and platelet count for ruling out varices needing treatment in patients with compensated advanced chronic liver disease. Assessment of aetiology specific cut-offs for ruling in and ruling out clinically significant portal hypertension is an unmet clinical need. The incorporation of spleen stiffness measurements in non-invasive algorithms using validated software and improved measuring scales might enhance the non-invasive diagnosis of portal hypertension in the next 5 years.

Full Text Available OBJECTIVE: To identiy left ventricular geometric patterns in hypertensive patients on echocardiography, and to correlate those patterns with casual blood pressure measurements and with the parameters obtained on a 24-hour ambulatory blood pressure monitoring. METHODS: We studied sixty hypertensive patients, grouped according to the Joint National Committee stages of hypertension.. Using the single- and two-dimensional Doppler Echocardiography, we analyzed the left ventricular mass and the geometric patterns through the correlation of left ventricular mass index and relative wall thickness. On ambulatory blood pressure monitoring we assessed the means and pressure loads in the different geometric patterns detected on echocardiography RESULTS: We identified three left ventricular geometric patterns: 1 concentric hypertrophy, in 25% of the patients; 2 concentric remodeling, in 25%; and 3 normal geometry, in 50%. Casual systolic blood pressure was higher in the group with concentric hypertrophy than in the other groups (p=0.001. Mean systolic pressure in the 24h, daytime and nighttime periods was also higher in patients with concentric hypertrophy, as compared to the other groups (p=0.003, p=0.004 and p=0.007. Daytime systolic load and nighttime diastolic load were higher in patients with concentric hypertrophy ( p=0.004 and p=0.01, respectively. CONCLUSIONS: Left ventricular geometric patterns show significant correlation with casual systolic blood pressure, and with means and pressure loads on ambulatory blood pressure monitoring.

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

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.

Mahoney, J.R.; Etkin, N.L.; McSwigan, J.D.; Eaton, J.W.

1982-01-01

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

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.

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.)

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

BACKGROUND: Prevalence surveys have consistently found that the blood pressure control rate among people with hypertension is less than 25%. Studies of telemedicine as a means of providing care to hypertensive patients have shown that this approach is effective in lowering blood pressure. Major design flaws and high operating costs, however, have hindered its adoption by physicians and patients. OBJECTIVES: In the present commentary, the field of telemedicine, as it pertains to hypertension management, is reviewed, and the investigators’ experiences in developing a new telemedicine system are outlined. METHODS: An applied qualitative case study approach was used to determine the information needs for the design of a telemedicine system. Opinions were elicited separately from type 2 diabetic patients with hypertension (n=24) and family practitioners in active clinical practice (n=18). RESULTS: Physician and patient focus group meetings provided key information that led to changes in the prototype system. The low level of computer and Internet use by patients in everyday life and by physicians in practice-related activities precluded their inclusion in the design of the system for information retrieval and receiving clinical alerts. For patients, the mobile phone appeared to be an acceptable alternative. The only practical, automated means to disseminate reports and alerts to physicians was by fax, which was the most universally available device in a doctor’s office. CONCLUSION: This tightly focused qualitative study led to the development of design principles for a prototype system, increasing the likelihood of user acceptance and improving its effectiveness.

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.

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.

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.

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

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. The indicators of the Papillary-Marginal-Attached Index in the main group were 55.49±1.96 points pointing out a severe degree of

To describe the health-related quality of life (HRQoL) profile of hypertensive population in Pakistan. A cross-sectional descriptive study was undertaken with a cohort of 385 hypertensive patients attending two public hospitals in Quetta city, Pakistan. The EuroQoL EQ-5D scale was used for the assessment of HRQoL. EQ-5D is a standardized instrument for use as a measure of health outcome and is used in the clinical and economic evaluation of health care as well as population health surveys. The HRQoL was scored using values derived from the UK general population survey. P ≤ 0.05 was taken as significant. Two hundred and sixty-five (68.85%) respondents were men with 3.01 ± 0.939 years of history of hypertension. Majority (n = 186, 48.3%) were categorized in age group of 28-37 years with mean age of 39.02 ± 6.596. Education, income and locality had significant relation with HRQoL score. HRQoL was measured poor in our study patients (0.4674 ± 0.2844). Hypertension has an adverse effect on patients' well-being and HRQoL. Results from this study could be useful in clinical practice, particularly in early treatment of hypertension, at point where improving HRQoL is still possible. © 2012 John Wiley & Sons Ltd.

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.

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 the absence of reliable, contemporary national data, the ACTION survey was designed to: a) provide preliminary data on stroke risk in the MEA (Middle East and Africa); b) describe the contribution of specific cardiovascular risk factors; 3) assess blood pressure (BP) control. This was a multi-center observational study in nine countries in the MEA region. From 2003 to 2005, 562 physicians from a variety of specialties recorded observations of cardiovascular risk factors in 4,747 hypertensive patients, aged 54-80 years. The 10-year absolute stroke risk was calculated using a scoring system based on the Framingham Heart Study observations, and comparisons made with an age-matched cohort. The mean 10-year stroke risk was estimated at 22.7% and was significantly higher for men (25.4%) than for women (19.5%) (P age-matched Framingham cohort, the estimated stroke risk in our population was almost double, and was significantly higher for females (212%) than for males (192%) (P < .001). Hypertension, diabetes, left ventricular hypertrophy, and smoking were major contributing risk factors, as were physical inactivity and elevated cholesterol. Blood pressure was controlled in only 18% of the population and in 12% of diabetics. Physicians of all specialties were willing to participate in stroke risk assessment. The risk of stroke in hypertensive patients in the MEA region is high, and is higher than would be predicted using Framingham data, particularly for females. Hypertension appears to be poorly controlled in more than 80% of hypertensive patients in the MEA region.

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 blood pressure assessment of each patient was done using standard techniques. Hypertensive diabetic subjects (Group-I, n=107) were compared with non-hypertensive diabetics (Group-II, n=93) for the presence of retinopathy. Results: Retinopathy and hypertension were observed in 51% and 53.5% of the total diabetic patients respectively. Hypertensive diabetic patients had significantly higher percentage of retinopathy compared to non-hypertensive diabetic patients (58 vs 43%; p<0.05). Conclusion: Retinopathy and hypertension are highly prevalent in our diabetic patients. The proportion of retinopathy is significantly more in hypertensive as compared to normotensive diabetics.

[Severe hypertension: definition and patients profiles].

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.

To determine the quality of prescribing in hypertension in primary and secondary health care settings using the Prescription Quality Index (PQI) tool and to assess the reliability of this tool. An observational cross-sectional study was carried out for 6 months in order to assess quality of prescribing of antihypertensive drugs using Prescription Quality Index (PQI) at four primary (PHC) and two secondary (SHC) health care facilities. Patients attending these facilities for at least 3 months were included. Complete medical history and prescriptions received were noted. Total and criteria wise PQI scores were derived for each prescription. Prescriptions were categorized as poor (score of ≤31), medium (score 32-33) and high quality (score 34-43) based on PQI total score. Psychometric analysis using factor analysis was carried out to assess reliability and validity. Total 73 hypertensive patients were included. Mean age was 61.2 ± 11 years with 35 (48%) patients above 65 years of age. Total PQI score was 26 ± 11. There was a significant difference in PQI score between PHC and SHC (P hypertensive patients was poor, somewhat better in primary as compared to secondary health care facility. PQI is reliable for measuring prescribing quality in hypertension in Indian set up.

Non-adherence to the treatment of chronic diseases such as hypertension and Diabetes Mellitus (DM) is a major obstacle in achieving patient therapy targets and quality of life of patients. A comprehensive approach involving pharmacists counselling has shown influences on changes in health behaviour and patient compliance. Behaviour changes in patients are one of the parameters to assess the effectiveness of counselling and education by pharmacists. Therefore, it is necessary to develop questionnaires of behaviour change measurement in DM-hypertension patients. This study aims to develop a measurement instrument in the form of questionnaires in assessing the behaviour change of DM-hypertension patients. Preparation of question items from the questionnaire research instrument refers to some guidelines and previous research references. Test of questionnaire instrument valid was done with expert validation, followed by pilot testing on 10 healthy respondents, and 10 DM-hypertension patients included in the inclusion criteria. Furthermore, field validation test was conducted on 37 patients who had undergone outpatient care at the PKU Muhammadiyah Yogyakarta City Hospital and The Gading Clinic in Yogyakarta. The inclusion criteria were male and female patients, aged 18-65, diagnosed with type 2 diabetes with hypertension who received oral antidiabetic drugs and antihypertensives, and who were not illiterate and co-operative. The data were collected by questionnaire interviews by a standardized pharmacist. The result of validation test using Person correlation shows the value of 0.33. The results of the questionnaire validation test on 37 patients showed 5 items of invalid questions with the value of r 0.33. The reliability value is shown from the Cronbach's alpha value of 0.722 (> 0.6), implying that the questionnaire is reliable for DM-hypertension patients. This Behavioural change questionnaire can be used on DM-hypertension patients, and an FGD approach is required

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

Unexplained liver injury including fibrosis and portal hypertension has rarely been reported among patients with HIV in the absence of co-infection with hepatitis B (HBV) or hepatitis C (HCV). We describe a series of HIV mono-infected patients with evidence of non-cirrhotic portal hypertension. HIV-infected patients with evidence of portal hypertension who were anti-HBV and anti-HCV negative and HBV and HCV RNA polymerase chain reaction (PCR) negative were identified from patients managed by the Victorian statewide HIV referral service located at The Alfred Hospital, Melbourne. Portal hypertension was defined as either radiological or endoscopic evidence of varices, portal vein flow obstruction, or elevated hepatic venous pressure gradient (HPVG). Five patients were found to have portal hypertension. These patients were male, aged 41 to 65 years, with known duration of HIV infection between 11 to 25 years. All had been treated with antiretroviral therapy, including didanosine. Tests for metabolic, autoimmune, and hereditary causes of liver disease failed to establish an etiology for the liver injury. All had radiological or endoscopic findings of varices, and four patients had radiological features of portal vein obstruction or flow reversal. Only one patient underwent HPVG measurement, which was elevated. Non-invasive fibrosis assessment revealed increased liver stiffness in three (out of four) patients, and no cirrhotic features were found on those who underwent liver biopsy. To our knowledge, this is the largest published series of non-cirrhotic portal hypertension in HIV mono-infected patients in Australia. Further research is needed to understand what relationship, if any, HIV or its treatments might have on liver injury over time. © 2012 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

Renal sympathetic denervation (RSD) is emerging as a new therapeutic option for patients with severe hypertension refractory to medical therapy. The presence of a renal artery stenosis may be both a cause of secondary hypertension and a contraindication to RSD if a renal artery stent is implanted; therefore, the definition of the functional importance of a renal artery stenosis in a patient with refractory hypertension is crucial. We describe the imaging and functional intravascular assessment of an angiographically severe stenosis of the renal artery in a patient with severe refractory hypertension, by means of intravascular ultrasound (IVUS), and measurement of the translesional pressure gradient with a pressure wire. Pressure wire examination excluded any severity of the stenosis, and IVUS showed the presence of a dissected plaque that resolved spontaneously after 3 months of intensive medical therapy and high-dose statin. Subsequently the patient was treated with RSD, achieving a significant effect on blood pressure control. Intravascular imaging and functional assessment of renal artery anatomy in patients with atherosclerotic disease may prove particularly suited to patients with refractory hypertension and multilevel vascular disease who are considered for endovascular therapies, either renal artery stenting or RSD.

In Jordan there is a paucity of research on hypertension and its risk factors among patients with type 2 diabetes mellitus. The study was designed to assess the prevalence of hypertension, risk factors and the level of awareness and control of hypertension among outpatients with type 2 diabetes. A cross-sectional study was carried out on a sample of 1000 patients with type 2 diabetes who were attending the National Center for Diabetes, Endocrine and Genetic Diseases for follow-up during the period of June to December 2006. Data were collected from medical records and through a structured interview questionnaire. Logistic regression analysis was used to assess the independent effect of variables on hypertension. The prevalence of hypertension (PB>130/80 or on medication for high blood pressure) was 72.4% (70.9% of males and 73.9% of females). The logistic regression indicated that hypertension was positively associated with age (P=0.001), body mass index (P=0.001). About one-half of patients who were aware of having hypertension failed to keep their blood pressure under control. Hypertension is a common co-morbidity among diabetic patients. Despite a high rate of awareness of hypertension among study subjects (93%), hypertension was not controlled to the recommended levels of blood pressure in one but a one-half (50.4%) of patients.

OBJECTIVE: Community health centers (HCs) provide care for millions of medically underserved Americans with disproportionate burdens of hypertension and hyperlipidemia. For both conditions, treatment guidelines recently became more stringent and quality improvement (QI) efforts have intensified. We assessed hypertension and hyperlipidemia management in HCs during this time of guideline revision and increased QI efforts. DESIGN: Cross-sectional chart review. SETTING AND PARTICIPANTS: Eleven Midwestern HCs for 2000 and 9 for 2002 provided audit data from 2,976 randomly chosen patients with hypertension and/or hyperlipidemia. MEASUREMENT: Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC VI/VII) and National Cholesterol Education Program Adult Treatment Panel (NCEP-ATP III) guidelines were used to assess management of these conditions. RESULTS: Hypertension (2000, N=808; 2002, N=692) and hyperlipidemia (2000, N=774; 2002, N=702) outcomes improved for specific clinical subgroups. Hypertensive patients with 1 or more cardiovascular risk factors demonstrated significant improvement (34% vs. 45% controlled at risk factors (39% vs. 58% controlled at risk groups; however, ongoing QI is necessary.

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.

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.

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

Our aim was to assess the ambulatory blood pressure monitoring (ABPM) characteristics or patterns in hypertensive patients with diabetes compared with non-diabetic hypertensives. We performed a cross-sectional analysis of a 68,045 patient database from the Spanish Society of Hypertension ABPM Registry, a nation-wide network of >1200 primary-care physicians performing ABPM under standardized conditions in daily practice. We identified 12,600 (18.5%) hypertensive patients with diabetes. When compared with patients without diabetes, diabetic hypertensives exhibited higher systolic blood pressure (BP) levels in every ABPM period (daytime 135.4 vs. 131.8, and nighttime 126.0 vs. 121.0 mm Hg, P<0.001 for both) despite they were receiving more antihypertensive drugs (mean number 1.71 vs. 1.23, P<0.001). Consequently, diabetic patients suffered from lack of control of BP more frequently than non-diabetic subjects particularly during the night (65.5% vs. 57.4%, P<0.001). Prevalence of a non-dipping BP profile (64.2% vs. 51.6%, P<0.001) was higher in diabetic patients. In the other hand, prevalence of 'white-coat' hypertension in diabetic patients was 33.0%. We conclude that there was a remarkably high prevalence of alterations in ABPM in patients with diabetes. Abnormalities in systolic BP, particularly during the night, and in circadian BP pattern could be linked with the excess of BP-related cardiovascular risk of diabetes. A wider use of ABPM in diabetic patients should be considered.

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...

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.

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

Nitro-oxidative stress may have pathophysiological consequences. The study aimed to assess the nitro-oxidative stress, the vascular growth factor, and metalloproteinase-9 levels in patients with noncirrohic and cirrhotic portal hypertension. Patients with noncirrhotic portal hypertension (n=50) and cirrhotic portal hypertension (n=50) from the 3rd Medical Clinic in Cluj-Napoca Romania were prospectively enrolled between October 2004 and October 2006. A control group of healthy volunteers (n=50) was also evaluated. Nitro-oxidative stress was assessed by measuring serum concentration of nitrites and nitrate, 3-nitrotyrosine, total oxidative status, total antioxidant reactivity, and oxidative stress index. Serum vascular growth factor and matrix metalloproteinase-9 were also determined. Serum nitrites and nitrate levels significantly increased in both noncirrhotic (pportal hypertension (p=0.057). 3-nitrotyrosine also increased in noncirrhotic (p=0.001) and cirrhotic portal hypertension patients (p=0.014). Total oxidative status showed a significant increase in noncirrhotic (pportal hypertension (pportal hypertension (pportal hypertension a significant systemic nitro-oxidative stress was found, correlated with an increase of VEGF. MMP-9 decreased in noncirrhotic portal hypertension.

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.

Substantial burden of diabetes and hypertension is on rise in India, leading to a twin epidemic. India, being a rural country, has unique problems regarding the treatment compliance which is a serious risk for morbidity and mortality. To assess the compliance to treatment of hypertension and diabetes amongst the diagnosed patients from rural area and to study reasons of non-compliance and knowledge and attitude. Community based, cross sectional, observational study conducted in the rural communities of Tara and Barapada villages of Raigad district of Maharashtra. Survey was conducted covering population of 2115 across 360 families, 250 at Barapada and 110 at Tara. All the cases of diabetes and hypertension diagnosed for more than one year were included. A structured and pre-tested questionnaire was administered including details on demography, medical documentation, treatment details and factors assessing the compliance, knowledge and attitude towards the diseases. When reviewed the treatment adherence pattern based on documentary evidence and interview of the patient, on history of taking medication strictly since the detection illness, it was found that more than 70% of the Diabetics and more than 75% of the Hypertensive have discontinued the treatment in between. The most common reasons of non-compliance is the lack of sufficient motivation for treatment adherence as many mentioned (61.4% diabetics, 55.8% hypertensives) difficulty to remember to take daily medication due to work or forgetfulness. This is followed by lack of money (50%diabetics, 55.8% hypertensives) and living far away from doctor in city (43% diabetics and 46% hypertensives). The study findings are only tip of iceberg and the non-adherence to the treatment of diabetes and hypertension in rural population is at alarmingly high. Illiteracy, lack of faith in treatment and motivation, unawareness and self-neglect as well as financial constraints and lack of specialist care in rural area is playing

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.

Hypertension control is often inadequate in HIV patients. In a contemporary, nationwide cohort of Italian HIV-infected adults, we assessed time trends in hypertension prevalence, awareness, treatment, and control. We also evaluated predictors of cardiovascular events and of new-onset hypertension. Multicenter prospective cohort study, sampling 961 consecutive HIV patients (71% men, mean age 46 ± 9 years, 30% hypertensive) examined in 2010-2014 and after a median follow-up of 3.4 years. Among hypertensive patients, hypertension awareness (63% at baseline and 92% at follow-up), treatment (54 vs. 79%), and control (35 vs. 59%) all improved during follow-up. The incidence of new-onset hypertension was 50.1/1000 person-years (95% confidence interval, 41.2-60.3). Multivariable-adjusted predictors of hypertension were age, BMI, estimated cardiovascular risk, blood pressure, and advanced HIV clinical stage.In total, 35 new cardiovascular events were reported during follow-up (11.1/1000 person-years). In a multivariate model, baseline cardiovascular risk and hypertensive status predicted incident cardiovascular events, whereas a higher CD4 cell count had a protective role. In treated hypertensive patients, the use of integrase strand transfer inhibitors at follow-up was associated with a lower SBP (average yearly change, -3.8 ± 1.6 vs. -0.9 ± 0.5 mmHg in integrase strand transfer inhibitor users vs. nonusers, respectively, P = 0.02). Hypertension awareness, treatment, and control rates all improved in adult Italian HIV patients over the last few years, although hypertension remains highly prevalent (41%) in middle-aged HIV patients, and significantly impacts cardiovascular morbidity. Traditional risk factors and advanced HIV disease predict new-onset hypertension, whereas CD4 cell count favorably affects future cardiovascular events.

Despite many years of study, questions remain about why patients do or do not take medicines and what can be done to change their behaviour. Hypertension is poorly controlled in the UK and poor compliance is one possible reason for this. Recent questionnaires based on the self-regulatory model have been successfully used to assess illness perceptions and beliefs about medicines. This study was designed to describe hypertensive patients' beliefs about their illness and medication using the self-regulatory model and investigate whether these beliefs influence compliance with antihypertensive medication. We recruited 514 patients from our secondary care population. These patients were asked to complete a questionnaire that included the Beliefs about Medicines and Illness Perception Questionnaires. A case note review was also undertaken. Analysis shows that patients who believe in the necessity of medication are more likely to be compliant (odds ratio (OR)) 3.06 (95% CI 1.74-5.38), Pcompliance influence it indirectly. The self-regulatory model is useful in assessing patients health beliefs. Beliefs about specific medications and about hypertension are predictive of compliance. Information about health beliefs is important in achieving concordance and may be a target for intervention to improve compliance.

Carotid intima-media thickness (cIMT) is an established surrogate marker of atherosclerosis. However, cIMT may not reflect the whole arterial changes occurring in various pathologic conditions, such as hypertension. The aim of this study was to evaluate whether vascular properties of carotid artery (CA) in patients with hypertension differ from those of patients with diabetes and controls before the progression of cIMT. Vascular properties of CA were assessed in 402 consecutive asymptomatic subjects who have normal cIMT (131 with hypertension, 151 with diabetes mellitus, and 120 controls). Conventional carotid stiffness indices calculated from vessel diameter and blood pressure, and parameters from velocity-vector imaging (VVI), including vessel area, fractional area change (FAC), radial velocity, circumferential strain, and strain rate were measured to assess the differences between the groups. In univariate analysis, both patients with hypertension and diabetes showed higher elastic modulus, lower distensibility coefficients and FAC of VVI than those of controls. However, when adjusting for baseline covariates, only FAC (odds ratio [OR] = 0.82, 95% confidence interval [CI] = 0.70-0.97, p = 0.025) and vessel area (OR = 2.84, 95% CI = 1.64-4.91, p hypertension from those of controls. Also, patients with hypertension showed larger vessel area than diabetes (OR = 2.58, 95% CI = 1.75-3.80, p hypertensive patients was stiffer than those of controls and positive remodeling preceded the wall thickening independent of baseline covariates.

An evaluation of myocardial fatty acid metabolism in hypertensive patients with major complication has not been previously established. To assess the myocardial fatty acid metabolism in hypertensive patients with intracranial hemorrhage (IH), we performed myocardial image using 123 I-15-p-iodophenyl-3-methyl pentadecanoic acid (BMIPP). Seventeen hypertensive patients with IH (HIH) and 27 hypertensive patients without IH (HT) were studied. A dose of 111 MBq of BMIPP was injected intravenously at rest, and a myocardial image was recorded 30 minutes after the injection. Myocardial perfusion image using Thallium-201 (Tl) was also performed within 2 weeks after BMIPP study. The regional myocardial uptakes of BMIPP and Tl were visually assessed in 17 segments with a four-point scoring system (0=absent to 3=normal uptake). Cardiac hypertrophy was evaluated by electrocardiogrpahy (ECG) and two-dimensional ultrasonic cardiography (UCG). Sum of uptake scores of Tl was similar in both groups (45.1±5.4 vs. 47.9±4.2), but that of BMIPP in HIH was lower than HT (35.9±7.9 vs 45.6±4.8, p<0.001). Evaluation of cardiac hypertrophy using ECG and UCG revealed no significant difference between two groups. HIH have much more eccentric hypertrophy in UCG study than HT (53% vs. 37%). These data suggest that hypertensive patients with intracranial hemorrhage have a more impaired myocardial fatty acid metabolism compared to the hypertensive patients with similar cardiac hypertrophy. BMIPP imaging might be useful to evaluate the severity of myocardial fatty acid metabolism in hypertensive patients. (author)

Obstructive sleep apnea (OSA) is a risk factor for the development of hypertension and cardiovascular disease. Apnea overloads the autonomic cardiovascular control system and may influence blood pressure variability, a risk for vascular damage independent of blood pressure levels. This study investigates the hypothesis that blood pressure variability is associated with OSA. In a cross-sectional study, 107 patients with hypertension underwent 24-h ambulatory blood pressure monitoring and level III polysomnography to detect sleep apnea. Pressure variability was assessed by the first derivative of blood pressure over time, the time rate index, and by the standard deviation of blood pressure measurements. The association between the apnea-hypopnea index and blood pressure variability was tested by univariate and multivariate methods. The 57 patients with apnea were older, had higher blood pressure, and had longer duration of hypertension than the 50 patients without apnea. Patients with apnea-hypopnea index (AHI) ≥ 10 had higher blood pressure variability assessed by the standard deviation than patients with AHI variability assessed by the time rate index presented a trend for association during sleep (P = 0.07). Daytime blood pressure variability was not associated with the severity of sleep apnea. Sleep apnea increases nighttime blood pressure variability in patients with hypertension and may be another pathway linking sleep abnormalities to cardiovascular disease.

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

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.

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. Hyperuricemia was present in 37.2% of the hypertensive patients with a frequency of 34.5% in the younger

Apart from seeking target organ damage, the investigation of hypertension is primarily aimed at finding a treatable cause of the hypertension. The finding of one such cause is usually construed as being the sole culprit responsible for the patient's elevated blood pressure. The existence of multiple aetiologies of secondary hypertension in one patient is infrequent. In this report, we describe such a patient in whom secondary hypertension due to Cushing's disease, renovascular and finally bar...

Parfenov, V A

2005-01-01

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.

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.

Left ventricular mass in borderline hypertension assessed by echo cardiography

Mezzasalma, L.; Ghione, S.; Palonebo, C.

1989-01-01

The relationship between clinical measurement of blood pressure (BP) and left ventricular hypertrophy in arterial hypertension appears to be weak in most studies. On the contrary, stronger correlations with target organ damage in general, and left ventricular hypertrophy in particular, have been reported for blood pressure measurements obtained by ambulatory monitoring; this finding may indicate a possible role for blood pressure response to naturally occurring stresses in determining left ventricular hypertrophy. Aim of this study was to investigate, in 18 patients with borderline arterial hypertension, the relationships between echocardiographically assessed left ventricular mass and, respectively, casual BP and BP responses to some standardized stress tests. Only three patients had a diastolic wall thickness of the interventricular septum and of the posterior wall ≥1.2 cm and none had a pathologically increased left ventricular mass index. The following statistically significant correlations were found: casual diastolic BP vs. left ventricular mass index (r=0.53, p<0.02), systolic BP response to bicycle exercise test vs. left ventricular mass index (r=0.55, p<0.05). Multiple regression analysis showed that almost fifty percent of the variability of left ventricular mass index could be predicted by these two BP measurements. These findings suggest that besides the chronically increased afterload, also the transient hypertensive responses to naturally occuring physical stresses may have a role in determining the extent of cardiac structural changes in borderline hypertensive patients. In addition, they indicate a direct relation between left ventricular mass and blood pressure levels also in borderline hypertension, as previously shown for established hypertension, despite the fact that left ventricular hypertrophy represents only an occasional finding in early stages of hypertension

It is assumed that doctor-patient relationship plays an effective role in patients' satisfaction, medication adherence, and health outcomes since exploring different aspects of this relationship, such as addressing medication adherence, has rarely been investigated. Therefore, the main aim of the present study was to assess the impact of patients' satisfaction derived from communicating with doctors on medication adherence in hypertensive patients. This cross-sectional survey was conducted on three hundred patients with hypertension, using multistage sampling technique in health care centers in Isfahan, Iran. Data were collected by two questionnaires comprised (1) patients' satisfaction derived from the relationship with doctors and (2) medication adherence named "Morisky Medication Adherence Scale" with 8 items. Multivariate logistic regression model was applied to test the odds ratio (OR) of patients' satisfaction resulting from the relationship with physicians in numerous aspects in two groups: appropriate and inappropriate medication adherence. A lower level of satisfaction derived from building the relationship (confidence interval [CI] =0.95, 0.06-0.71 and OR = 0.20) and empathy subscales (CI = 0.95, 13-0.80 and OR = 0.33) was associated with nonadherence to treatment after controlling the physicians' gender and patients' age, gender, education, and duration of disease. Patients' satisfaction resulting from building the relationship and empathy with physicians appeared to be associated with medication adherence among hypertensive patients.

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.

Many treatment options are now available for patients with idiopathic pulmonary arterial hypertension (IPAH). Data regarding the optimal combination of therapies are lacking, as is consensus on how to assess response to therapy and when to change therapeutic regimens. To gather the opinions of Canadian pulmonary hypertension (PH) experts regarding standard practice in the care of IPAH patients after therapy is initiated. Canadian PH physicians were surveyed using short questionnaires to assess their opinions and practices in the care of IPAH patients. A Delphi forecasting approach was used to gain consensus among Canadian physicians on the most important clinical parameters to consider when assessing patients after the initiation of therapy. Twenty-six of 37 Canadian PH experts who were invited to participate completed the study. All endorsed the use of combination therapy for IPAH patients despite the lack of universal provincial coverage for this approach. By consensus, WHO functional class, 6 min walk distance and hospitalization for right heart failure were the most important clinical parameters. The most highly rated physical examination parameters were jugular venous pressure, peripheral edema, the presence of ascites and body weight. The overall approach to care of IPAH patients is similar across PH centres in Canada. A limited number of clinical and physical examination parameters were considered to be most important to reassess patients after therapy is initiated. These parameters, along with definition of threshold values, will facilitate the development of standard practice guidelines for IPAH patients in Canada.

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.

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

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.

To assess the morphology of thoracic aorta, we had a trial of Gd-DTPA enhanced ultrafast cine MR imaging on the thoracic aorta. This method was provided with high quality thoracic aortogram during 15-20 seconds. In patients without hypertension and aortic valve disease, dimensions of ascending aorta and aortic arch were significantly correlated with aging. In patients with hypertension, dimensions of ascending aorta and aortic arch were significantly dilated. In patients with aortic valve disease, thoracic aorta was diffusely enlarged, especially in ascending aorta. Gd-DTPA enhanced ultrafact cine MR imaging was useful to assess the thoracic aortic anatomy and diseases. (author)

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.

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.

Non-communicable diseases, including diabetes mellitus and hypertension, continue to disproportionately burden low- and middle-income countries. However, little research has been done to establish current practices and management of chronic disease in these settings. The objective of this study was to examine current clinical management and identify potential gaps in care of patients with diabetes mellitus and hypertension in the district of Toledo, Belize. The study used a mixed methodology to assess current practices and identify gaps in diabetes mellitus and hypertension care. One hundred and twenty charts of the general clinic population were reviewed to establish disease epidemiology. One hundred and seventy-eight diabetic and hypertensive charts were reviewed to assess current practices. Twenty providers completed questionnaires regarding diabetes mellitus and hypertension management. Twenty-five individuals with diabetes mellitus and/or hypertension answered a questionnaire and in-depth interview. The prevalence of diabetes mellitus and hypertension was 12%. Approximately 51% (n = 43) of patients with hypertension were at blood pressure goal and 26% (n = 21) diabetic patients were at glycemic goal based on current guidelines. Of the patients with uncontrolled diabetes, 49% (n = 29) were on two oral agents and only 10% (n = 6) were on insulin. Providers stated that barriers to appropriate management include concerns prescribing insulin and patient health literacy. Patients demonstrated a general understanding of the concept of chronic illness, however lacked specific knowledge regarding disease processes and self-management strategies. This study provides an initial overview of diabetes mellitus and hypertension management in a diverse patient population in rural Belize. Results indicate areas for future investigation and possible intervention, including barriers to insulin use and opportunities for lifestyle-specific disease education for

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.

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

There are high growing prevalence rates of hypertension in South Africa. Consequently, there is a need to assess knowledge and management among hypertensive patients receiving chronic medication from primary health care (PHC) facilities in South Africa as a basis for improving future management. This is important as South Africa seeks to improve its management of chronic diseases. Descriptive, quantitative study amongst chronic hypertensive patients in the chronic disease programme. Patients were interviewed face-to-face by trained pharmacists using a structured questionnaire. Data analysis included descriptive and inferential statistics. Half (53.7%) of the patients had uncontrolled blood pressure (BP). Less than a third of patients (27.7%) knew what hypertension is, the meaning of recorded BP numbers (4.5%), and what normal BP should be (19.9%). All patients who knew the meaning of BP numbers had formal education (p = 0.047). Only 15.6% of the 56.0% patients, who received hypertension information, received it on antihypertensive medicines specifically. The majority of the patients lacked hypertension specific knowledge and only half had controlled BP. Interventions to improve the control of high BP should be targeted at closing knowledge gaps as part of the current chronic treatment initiatives in South Africa to ensure the benefits of increased access to care are realized.

The SBP values to be achieved by antihypertensive therapy in order to maximize reduction of cardiovascular outcomes are unknown; neither is it clear whether in patients with a previous cardiovascular event, the optimal values are lower than in the low-to-moderate risk hypertensive patients, or a more cautious blood pressure (BP) reduction should be obtained. Because of the uncertainty whether 'the lower the better' or the 'J-curve' hypothesis is correct, the European Society of Hypertension and the Chinese Hypertension League have promoted a randomized trial comparing antihypertensive treatment strategies aiming at three different SBP targets in hypertensive patients with a recent stroke or transient ischaemic attack. As the optimal level of low-density lipoprotein cholesterol (LDL-C) level is also unknown in these patients, LDL-C-lowering has been included in the design. The European Society of Hypertension-Chinese Hypertension League Stroke in Hypertension Optimal Treatment trial is a prospective multinational, randomized trial with a 3 × 2 factorial design comparing: three different SBP targets (1, hypertension and a stroke or transient ischaemic attack 1-6 months before randomization. Antihypertensive and statin treatments will be initiated or modified using suitable registered agents chosen by the investigators, in order to maintain patients within the randomized SBP and LDL-C windows. All patients will be followed up every 3 months for BP and every 6 months for LDL-C. Ambulatory BP will be measured yearly. Primary outcome is time to stroke (fatal and non-fatal). Important secondary outcomes are: time to first major cardiovascular event; cognitive decline (Montreal Cognitive Assessment) and dementia. All major outcomes will be adjudicated by committees blind to randomized allocation. A Data and Safety Monitoring Board has open access to data and can recommend trial interruption for safety. It has been calculated that 925 patients would reach the primary

Full Text Available The prevalence of resistant hypertension (RHT still remains unknown. 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.

Full Text Available Background: It is assumed that doctor-patient relationship plays an effective role in patients' satisfaction, medication adherence, and health outcomes since exploring different aspects of this relationship, such as addressing medication adherence, has rarely been investigated. Therefore, the main aim of the present study was to assess the impact of patients' satisfaction derived from communicating with doctors on medication adherence in hypertensive patients. Materials and Methods: This cross-sectional survey was conducted on three hundred patients with hypertension, using multistage sampling technique in health care centers in Isfahan, Iran. Data were collected by two questionnaires comprised (1 patients' satisfaction derived from the relationship with doctors and (2 medication adherence named “Morisky Medication Adherence Scale” with 8 items. Multivariate logistic regression model was applied to test the odds ratio (OR of patients' satisfaction resulting from the relationship with physicians in numerous aspects in two groups: appropriate and inappropriate medication adherence. Results: A lower level of satisfaction derived from building the relationship (confidence interval [CI] =0.95, 0.06–0.71 and OR = 0.20 and empathy subscales (CI = 0.95, 13–0.80 and OR = 0.33 was associated with nonadherence to treatment after controlling the physicians' gender and patients' age, gender, education, and duration of disease. Conclusion: Patients' satisfaction resulting from building the relationship and empathy with physicians appeared to be associated with medication adherence among hypertensive patients.

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.

White-Coat Effect Is Uncommon in Patients With Refractory Hypertension.

Siddiqui, Mohammed; Judd, Eric K; Oparil, Suzanne; Calhoun, David A

2017-09-01

Refractory hypertension is a recently described phenotype of antihypertensive treatment failure defined as uncontrolled blood pressure (BP) despite the use of ≥5 different antihypertensive agents, including chlorthalidone and spironolactone. Recent studies indicate that refractory hypertension is uncommon, with a prevalence of ≈5% to 10% of patients referred to a hypertension specialty clinic for uncontrolled hypertension. The prevalence of white-coat effect, that is, uncontrolled automated office BP ≥135/85 mm Hg and controlled out-of-office BP hypertensive patients overall is ≈30% to 40%. The prevalence of white-coat effect among patients with refractory hypertension has not been previously reported. In this prospective evaluation, consecutive patients referred to the University of Alabama at Birmingham Hypertension Clinic for uncontrolled hypertension were enrolled. Refractory hypertension was defined as uncontrolled automated office BP ≥135/85 mm Hg with the use of ≥5 antihypertensive agents, including chlorthalidone and spironolactone. Automated office BP measurements were based on 6 serial readings, done automatically with the use of a BpTRU device unobserved in the clinic. Out-of-office BP measurements were done by 24-hour ambulatory BP monitor. Thirty-four patients were diagnosed with refractory hypertension, of whom 31 had adequate ambulatory BP monitor readings. White-coat effect was present in only 2 patients, or 6.5% of the 31 patients with refractory hypertension, suggesting that white-coat effect is largely absent in patients with refractory hypertension. These findings suggest that white-coat effect is not a common cause of apparent lack of BP control in patients failing maximal antihypertensive treatment. © 2017 American Heart Association, Inc.

Metabolic syndrome in hypertensive patients: An unholy alliance

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.

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.

Portal hypertension can lead to oesophageal varices (EV) and portal hypertensive gastropathy (PHG). The aim of this study is to determine the relationship between severity of Portal hypertensive gastropathy and size of oesophageal varices. Methods: One hundred and ninety-five patients of hepatitis C positive chronic liver disease having oesophageal varices were assessed for severity of portal hypertensive gastropathy. Results: Mild Portal Hypertensive Gastropathy was observed in 16 (8.2 %), moderate in 54 (27.7 %) and severe in 120 (61.6 %) patients. Grade 1 Oesophageal Varices were present in 79 (40.5%) patients, grade 2 in 44(21.9%) patients, grade 3 in 62 (31.8%) and grade 4 in 10 (5.2%) patients. No significant correlation was observed between grades of gastropathy and size of varices. Conclusion: The frequency of portal hypertensive gastropathy was 97.5% in Hepatitis C positive cirrhotic patients having oesophageal varices. Severity of gastropathy is not related to the grade or size of oesophageal varices. (author)

To assess absolute cardiovascular risk and co-morbidities in uncontrolled hypertensive patients (blood pressure [BP]>or=140/90 mmHg or>or=130/80 mmHg in diabetics) attending Primary Care Physicians in Spain, and to determine the attitudes of these physicians towards this problem. Cross-sectional, multicenter study involving 356 general practitioners around Spain. Absolute cardiovascular risk was assessed according to ESH-ESC 2003 Guidelines in a sample of 1,710 patients. Two hundred ninety seven patients were excluded by several reasons and a total of 1,413 hypertensive patients were valuable (mean age: 65.3+/-11.4 years; 56.7% women). Normal BP values (or=180/110 mmHg) by 7.9%. Associated cardiovascular risk factors were observed in 96.0% of patients (95% CI=94.7-97.2%), target organ damage in 34.5% (95% CI=31.6-36.5%), and cardiovascular clinical disease in 36.0% (95% CI=33.5-38.5%). According to ESH-ESC 2003 Guidelines 34.0% (CI=31.5-38.2%) were at very-high risk; 29.4% (95% CI=26.4-32.8%) at high risk; 30.4% (95% CI=27.2-33.7%) at moderate risk and 5.4% (95% CI=3.9-7.2%) at low risk of cardiovascular disease. Despite the high absolute risk, physicians did not do any therapeutic change in 30.4% (95% CI=28.2-33.5%) of uncontrolled hypertensive patients. Most of them (64.26%) considered that bad compliance to life style changes was the reason for inadequate BP control. The most frequent measure introduced was the association of additional drugs. Absolute cardiovascular risk in uncontrolled hypertensive patients attending Primary Care Physicians in Spain is very relevant. Sixty-five percent of these patients are at high or very high risk with a high prevalence of target organ damage or associated cardiovascular clinical disease. Therapeutic attitudes towards these patients are still very conservative although they are improving compared with previous studies.

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

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)

Assessment of global risk: a foundation for a new, better definition of hypertension.

Science.gov (United States)

Giles, Thomas D

2006-08-01

The prevalence of individuals with increased blood pressure (BP) is growing. A greater understanding of the various pathogenetic mechanisms of hypertension and associated BP increases would provide a better strategy for preventing and treating this condition. Hypertension is strongly associated with other cardiovascular risk factors. Additionally, there is no threshold of BP >115/70 mm Hg that identifies cardiovascular risk (i.e., risk is linear and doubles for each 20/10-mm Hg BP rise). These insights have led a group of hypertension experts to propose a new definition of hypertension as "a progressive cardiovascular syndrome arising from complex and interrelated etiologies," which features early markers that are "often present before blood pressure elevation is sustained." Early cardiovascular markers include widened pulse pressure, left ventricular hypertrophy, increased arterial stiffness, endothelial dysfunction, and microalbuminuria. Importantly, antihypertensive treatment for patients with prehypertension (systolic BP of 120-139 mm Hg or diastolic BP of 80-89 mm Hg) has recently been shown to prevent the development of frank hypertension. This revision of the definition of hypertension and the need to assess BP levels in the context of global cardiovascular risk should lead to earlier detection of at-risk patients.

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.

Appropriate management of hypertension reduces the risk of death from stroke and cardiac disease and includes routine assessment for target organ damage and estimation of cardiovascular risk. However, implementation of evidence-based hypertension management guidelines is unsatisfactory. We explore the use of audit and feedback as a quality improvement (QI) strategy for reducing the knowledge practice gap in hypertension care in a resource poor setting. The aim of this study is to determine the level of compliance to evidence-based guidelines on assessment of cardiovascular risk and target organ damage among patients with hypertension in Thika Level 5 Hospital in central Kenya and to implement best practice with regard to evidence utilisation among clinicians in the hospital. A retrospective clinical audit done in three phases spread over 5 months. Phase one involved identifying five audit criteria on assessment of cardiovascular risk and target organ damage in patients with hypertension and conducting a baseline audit in which compliance to audit criteria, blood pressure control and drug prescription practices were assessed. Phase two involved identifying barriers to compliance to audit criteria and strategies to overcoming these barriers. The third phase was a follow-up audit. There was no use of a cardiovascular risk assessment tool in both audits (0% vs. 0%; P = 1.00). Testing urine for haematuria and proteinuria reduced from 13% to 8% (P = 0.230) while taking a blood sample for measuring blood glucose, electrolytes and creatinine levels improved from 11% to 17% (P = 0.401). Performance of fundoscopy and electrocardiography remained unchanged at 2% and 8%, respectively (P = 0.886 and P = 0.898). High patient load was identified as the biggest barrier to implementation of best practice. Blood pressure control improved from 33% to 70% (P ≤ 0.001), whereas the proportion of patients on two or more recommended antihypertensive drugs rose

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.

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.

The prognostic value of screening multiple target organ damages (TODs) in hypertensive subjects has not been extensively studied. We estimated the prognostic value of considering 3 TODs in estimating the 10-year survival in hypertensive subjects. At baseline 1,848 out of a cohort of 1,963 hypertensive patients had a previous cardiovascular disease (CVD) or assessments of 3 TODs: Modification in Diet in Renal Disease (MDRD) 300mg/day, Sokolow index >3.5 mV, and advanced hypertensive retinopathy (grades 3 and 4 of Keith-Wagener-Barker classification). The cohort was divided into 5 groups: 0 TOD (N = 978), 1 TOD (N = 308), 2 TODs (N = 94), 3 TODs (N = 30), and previous CVD (N = 438). After 10 years of follow-up, we observed 418 deaths of which 254 from cardiovascular cause. The adjusted hazard ratios for the major cardiovascular risk factors showed a progressive risk associated with the number of TODs. For all-cause death, the hazard ratios [95% confidence intervals] vs. 0 TOD of the other 4 groups were 1.91 [1.39-2.63], 1.99 [1.28-3.10], 4.33 [2.42-7.72], and 3.09 [2.35-4.05], respectively. For cardiovascular death, the hazard ratios [95% confidence intervals] were of the same order of magnitude: 2.14 [1.38-3.32], 2.12 [1.15-3.89], 4.22 [1.83-9.72], and 4.24 [2.95-6.11], respectively. Our results indicate that hypertensive patients with several TODs had a worst outcome. Thus, it seems important to screen for multiple TODs in hypertension; especially check for severe hypertensive retinopathy in patients with left ventricular hypertrophy (LVH) and renal damage. © American Journal of Hypertension, Ltd 2015.

Full Text Available Objective. The aim of this study was to assess the impact of RD in conjunction with pulmonary vein isolation (PVI on patients with atrial fibrillation (AF and moderate resistant or severe resistant hypertension.Methods. The data for this study were obtained from two different prospective randomized trials and evaluated by means of meta-analysis. Patients with paroxysmal or persistent AF and moderate resistant hypertension (BP ≥140/90 mm Hg and <160/100 mm Hg; n = 60 or resistant hypertension (≥160/100 mm Hg; second study; n = 50 were randomized to PVI or PVI with RD groups and followed up during 18 months. Results. Each group had 55 patients. At 18-months, 35 (63.6% of the 55 PVI with RD group patients were AF-free vs 22 (40% of the 55 patients in the PVI-only group (p = 0.013; log-rank test. In patients with severe hypertension, 16 (64% of the 25 PVI with RD group patients vs 6 (24% of the 25 PVI-only group patients were AF-free (p = 0.004; log-rank test. For moderate hypertension, the differences were less dramatic: 16 (53.3% of 30 vs 19 (63.3% of 30 when RD was added (p = 0.43. Superior efficacy of adding RD was most apparent in persistent AF and resistant hypertension (probability risk 0.24 95%, confidence interval 0.08–0.69, p = 0.012. Conclusion. RD improves the outcomes of PVI, especially in patients with persistent AF and resistant hypertension.

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.

The objective of this multicenter cross-sectional study was to investigate the relationship of nocturnal polyuria in patients with common lifestyle related diseases and overactive bladder, with special attention to hypertension. After baseline assessment, patients recorded 24-hour urinary frequency/volume, blood pressure and heart rate for 3 days. They were stratified into 4 groups based on mean blood pressure, including no hypertension, and controllable, untreated and uncontrolled hypertension, respectively. The 2,353 eligible patients, who had urinary urgency once or more per week and 1 or more nocturnal toilet visits, were enrolled from 543 sites in Japan. Of these patients complete data, including the 24-hour frequency volume chart, were collected from 1,271. Multivariable analyses showed a statistically significant association of nocturnal polyuria with increasing age (OR 1.04, 95% CI 1.02-1.05, p polyuria in women alone (p = 0.01 and 0.03, respectively). Lower urinary tract symptoms suggestive of benign prostatic hyperplasia were significantly associated with nocturnal polyuria in men alone (p polyuria was significantly associated with age, male gender, and untreated hypertension in patients with lifestyle related diseases and overactive bladder. The association between hypertension and nocturnal polyuria was significant in women alone. Copyright © 2017 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Full Text Available Background: Systemic hypertension is highly prevalent and an important risk factor for cardiovascular events. Blood pressure control in hypertensive patients enrolled in the Hiperdia Program, a program of the Single Health System for the follow-up and monitoring of hypertensive patients, is still far below the desired level. Objective: To describe the epidemiological profile and to assess blood pressure control of patients enrolled in Hiperdia, in the city of Novo Hamburgo (State of Rio Grande do Sul, Brazil. Methods: Cross-sectional study with a stratified cluster random sample, including 383 adults enrolled in the Hiperdia Program of the 15 Basic Health Units of the city of Porto Alegre, conducted between 2010 and 2011. Controlled blood pressure was defined as ≤140 mmHg × 90 mmHg. The hypertensive patients were interviewed and their blood pressure was measured using a calibrated aneroid device. Prevalence ratios (PR with 95% confidence interval, Wald's χ2 test, and simple and multiple Poisson regression were used in the statistical analysis. Results: The mean age was 63 ± 10 years, and most of the patients were females belonging to social class C, with a low level of education, a sedentary lifestyle, and family history positive for systemic hypertension. Diabetes mellitus (DM was observed in 31%; adherence to the antihypertensive treatment in 54.3%; and 33.7% had their blood pressure controlled. DM was strongly associated with inadequate BP control, with only 15.7% of the diabetics showing BP considered as controlled. Conclusion: Even for hypertensive patients enrolled in the Hiperdia Program, BP control is not satisfactorily reached or sustained. Diabetic hypertensive patients show the most inappropriate BP control.

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.

The aim of this paper is to describe the design and the preliminary validation of a platform developed to collect and automatically analyze biomedical signals for risk assessment of vascular events and falls in hypertensive patients. This m-health platform, based on cloud computing, was designed to be flexible, extensible, and transparent, and to provide proactive remote monitoring via data-mining functionalities. A retrospective study was conducted to train and test the platform. The developed system was able to predict a future vascular event within the next 12 months with an accuracy rate of 84 % and to identify fallers with an accuracy rate of 72 %. In an ongoing prospective trial, almost all the recruited patients accepted favorably the system with a limited rate of inadherences causing data losses (<20 %). The developed platform supported clinical decision by processing tele-monitored data and providing quick and accurate risk assessment of vascular events and falls.

Effect of Age on Hypertension: Analysis of Over 4,800 Referred Hypertensive Patients

Directory of Open Access Journals (Sweden)

Anderson Gunnar

1999-01-01

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.

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

To compare the Doppler velocity waveform pattern of ophthalmic artery of hypertensive patients with that of normotensive subjects. Doppler velocity waveform was obtained from ophthalmic artery in 45 hypertensive patients and 60 normotensive subjects. Both hypertensives and normotensive subjects were classified according to age into those younger than and those older than 45 years. Doppler indices(pulsatility index(PI), resistance index(RI), the first systolic peak/the second systolic peak(S1/S2), the first systolic peak/diastolic peak(S1/D)) measured in hypertensive patients were compared with normotensive subjects. Among the various doppler indices, only S1/S2 showed significant difference(P < 0.05) between the hypertensive patients and normotensive subjects younger than 45 years. Doppler velocity waveform of hypertensive patients older than 45 years showed no significant difference from that of normotensive subjects with corresponding age. Doppler velocity waveform of ophthalmic artery in hypertensive patients younger than 45 years shows pattern with S2 higher than that of normotensive subjects. High S2 component(reflective-wave) may represent increased vascular impedance due to vasococonstriction of retinal arterioles in hypertensive patients

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.

Full Text Available OBJECTIVE: To evaluate the efficacy, safety and tolerability of sildenafil among Brazilian patients with hypertension treated with combinations of anti-hypertensive drugs. MATERIALS AND METHODS: One hundred twenty hypertensive men aged 30 to 81 years old under treatment with 2 or more anti-hypertensive drugs and with erectile dysfunction (ED lasting for at least 6 months were enrolled at 7 research centers in Brazil. Patients were randomized to receive treatment with either sildenafil or placebo taken 1 hour before sexual intercourse (initial dose of 50 mg, adjusted to 25 mg or 100 mg according to efficacy and toxicity. During the following 8 weeks, patients were evaluated regarding vital signs, adverse events, therapeutic efficacy, satisfaction with treatment and use of concurrent medications. RESULTS: The primary evaluation of efficacy, which was based on responses to questions 3 and 4 of the International Index of Erectile Function, showed significant differences regarding treatment with sildenafil (p = 0.0002 and p < 0.0001, respectively. In the assessment of global efficacy, 87% of the patients treated with sildenafil reported improved erections, as compared with 37% of patients given placebos (p < 0.0001. The other secondary evaluations supported the results favoring sildenafil. The most frequent adverse events among patients treated with sildenafil were headaches (11.4%, vasodilation (11.4% and dyspepsia (6.5%. There were no significant changes in blood pressure measurements in both groups. CONCLUSION: Sildenafil is efficacious and safe for the treatment of hypertensive patients with ED who receive concurrent combinations of anti-hypertensive drugs.

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.

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)

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.

The morbidity and mortality benefits of lowering blood pressure (BP) in hypertensive patients are well established, with most individuals requiring multiple agents to achieve BP control. Considering the important role of the renin-angiotensin-aldosterone system (RAAS) in the pathophysiology of hypertension, a key component of combination therapy should include a RAAS inhibitor. Angiotensin receptor blockers (ARBs) lower BP, reduce cardiovascular risk, provide organ protection, and are among the best tolerated class of antihypertensive therapy. In this article, we discuss two ARB combinations (valsartan/hydrochlorothiazide [HCTZ] and amlodipine/valsartan), both of which are indicated for the treatment of hypertension in patients not adequately controlled on monotherapy and as initial therapy in patients likely to need multiple drugs to achieve BP goals. Randomized, double-blind studies that have assessed the antihypertensive efficacy and safety of these combinations in the first-line treatment of hypertensive patients are reviewed. Both valsartan/HCTZ and amlodipine/valsartan effectively lower BP and are well tolerated in a broad range of patients with hypertension, including difficult-to-treat populations such as those with severe BP elevations, prediabetes and diabetes, patients with the cardiometabolic syndrome, and individuals who are obese, elderly, or black. Also discussed herein are patient-focused perspectives related to the use of valsartan/HCTZ and amlodipine/valsartan, and the rationale for use of single-pill combinations as one approach to enhance patient compliance with antihypertensive therapy.

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.

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

Many studies have reported the negative effects of depression on adherence to antihypertensive medication. However, little is known about the mechanism underlying this relationship in elderly patients with hypertension. The aim of this cross-sectional study is to examine the mediating role of self-efficacy in the relationship between depression and medication adherence among older patients with hypertension. The data were collected from October to December 2014. A total of 255 older patients with hypertension were assessed using the Geriatric Depression Scale, the Self-efficacy for Appropriate Medication Use Scale, and the Morisky Medication Adherence Scale. Hierarchical linear regression analysis and the Sobel test were used to examine the mediating role of self-efficacy in the relationship between depression and medication adherence. Depression and self-efficacy were statistically significant predictors of medication adherence in older patients with hypertension. Self-efficacy partially mediated the relationship between depression and medication adherence. Interventions targeting self-efficacy could increase the confidence of patients in their ability to actively take their medicines. Moreover, health care providers should be aware of the importance of early detection of depression in older patients with hypertension. Future studies with longitudinal data are warranted to clarify the multidirectional relationships between depression, self-efficacy, and medication adherence. © 2017 John Wiley & Sons Australia, Ltd.

It has been shown that short-term exercise training improves insulin resistance parameters in patients with ischaemic heart disease. The effects of such a rehabilitation programme in patients with hypertension have not been well established. To assess whether short-term endurance training after coronary artery bypass grafting (CABG) may improve metabolic parameters and reduce blood pressure in patients with hypertension. The study group consisted of 30 male patients (15 with hypertension and 15 normotensive) aged 55+/-2.1 years who underwent CABG 1 to 6 months before the initiation of a 3-week endurance training. Glucose, insulin and C-peptide blood levels as well as binding and degradation of 125I-insulin by erythrocyte receptors were assessed before and after the training programme. The effects of training on blood pressure values were also evaluated. A significant improvement (phypertension. This was accompanied by a significant (phypertension, both the exercise systolic and diastolic pressures decreased significantly (pendurance training was especially effective in patients with hypertension in whom beneficial changes in some metabolic risk factors of ischaemic heart disease as well as the reduction in the blood pressure values were observed.

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.

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)

Hemodynamics in patients with hypertensive intracerebral hemorrhage

Kitahara, Tetsuhiro

1997-01-01

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 potential role of renal denervation (RD) in patients with AF and less severe hypertension is unknown. The purpose of this study was to assess the potential role of RD as an adjunct to pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF) and moderate resistant or severe resistant hypertension. The data for this study were obtained from 2 different prospective randomized studies, analyzed by meta-analysis. Patients with paroxysmal AF or persistent AF and moderate resistant hypertension (office blood pressure BP ≥140/90 mm Hg and hypertension (≥160/100 mm Hg; second study; n = 38) were randomized to PVI or PVI with RD. At 12 months, 26 of the 41 PVI with RD patients (63%) were AF-free vs 16 of the 39 patients (41%) in the PVI-only group (P = .014). In patients with severe hypertension, 11 of the 18 PVI with RD patients (61%) vs 5 of the 18 PVI-only patients (28%) were AF-free (P = .03). For moderate hypertension, the differences were less dramatic: 11 of 21 (52%) vs 15 of 23 (65%) when RD added (P = .19). The superior efficacy of adding RD was most apparent in persistent AF and severe hypertension (hazard ratio 0.25, confidence interval 0.09-0.72, P = .01). Duration of the procedure and fluoroscopy were nonsignificantly longer in the RD group. RD may improve the results of PVI in patients with persistent AF and/or severe resistant hypertension.

The purpose of this study was to determine the usefulness of point shear wave elastography (p-SWE) of the liver and spleen for the detection of portal hypertension in pediatric patients. The study consisted of 38 healthy children and 56 pediatric patients with biopsy-proven liver disease who underwent splenic and liver p-SWE. The diagnostic performance of p-SWE in detecting clinically significant portal hypertension was assessed using receiver operating characteristic (ROC) curves. Reliable measurements of splenic and liver stiffness with p-SWE were obtained in 76/94 (81%) and 80/94 patients (85%), respectively. The splenic stiffness was highest in the portal hypertension group (Pportal hypertension was lower for splenic p-SWE than for liver p-SWE (0.906 vs. 0.746; P=0.0239). The cut-off value of splenic p-SWE for portal hypertension was 3.14m/s, with a specificity of 98.59% and a sensitivity of 68.18%. The cut-off value of liver p-SWE for portal hypertension was 2.09m/s, with a specificity of 80.28% and a sensitivity of 77.27%. In pediatric patients, p-SWE is a reliable method for detecting portal hypertension. However, splenic p-SWE is less accurate than liver p-SWE for the diagnosis of portal hypertension.

Background Aortic stiffness and epicardial fat relate to cardiovascular risk. Their relationship with each other and their role with hypertension, diabetes mellitus (DM), and myocardial infarction (MI) can be evaluated by cardiac magnetic resonance (CMR). Purpose To explore an association between aortic stiffness and epicardial as well as paracardial fat volume (EFV and ParaFV, respectively) in hypertensive patients and to relate the results to the presence of DM and MI. Material and Methods A total of 156 hypertensive and 20 non-hypertensive participants were examined at 1.5 Tesla. A 2D-velocity-encoded sequence was acquired to assess aortic pulse wave velocity (PWV in m/s) as a measure of aortic stiffness. A 3D-Dixon sequence was used to determine EFV and ParaFV. Results PWV correlated with EFV (R = 0.474; P hypertensive controls compared to hypertensive patients. EFV and PWV were significantly higher in diabetic hypertensive patients without MI (n = 19; PWV: 10.4 ± 2.9; EFV: 92.5 ± 19.3) compared to hypertension-only patients (n = 84 [no DM or MI]; EFV: 64.8 ± 25.1, PWV: 9.0 ± 2.6; P hypertensive patients. Both were increased in the presence of DM; however, only EFV was increased in the presence of MI. This may relate to the PWV lowering effect of the antihypertensive medication used by hypertensive patients and underscores the benefit of EFV assessment in this regard.

[Pregnancy in pulmonary arterial hypertension patients].

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.

To explore the relationship of liver and spleen shear wave velocity in patients with liver cirrhosis combined with portal hypertension, and assess the value of liver and spleen shear wave velocity in predicting the prognosis of patients with portal hypertension. All 67 patients with liver cirrhosis diagnosed as portal hypertension by hepatic venous pressure gradient in our hospital from June 2014 to December 2014 were enrolled into this study. The baseline information of these patients was recorded. Furthermore, 67 patients were followed-up at 20 mo after treatment, and liver and spleen shear wave velocity were measured by acoustic radiation force impulse at the 1 st week, 3 rd month and 9 th month after treatment. Patients with favorable prognosis were assigned into the favorable prognosis group, while patients with unfavorable prognosis were assigned into the unfavorable prognosis group. The variation and difference in liver and spleen shear wave velocity in these two groups were analyzed by repeated measurement analysis of variance. Meanwhile, in order to evaluate the effect of liver and spleen shear wave velocity on the prognosis of patients with portal hypertension, Cox's proportional hazard regression model analysis was applied. The ability of those factors in predicting the prognosis of patients with portal hypertension was calculated through receiver operating characteristic (ROC) curves. The liver and spleen shear wave velocity in the favorable prognosis group revealed a clear decline, while those in the unfavorable prognosis group revealed an increasing tendency at different time points. Furthermore, liver and spleen shear wave velocity was higher in the unfavorable prognosis group, compared with the favorable prognosis group; the differences were statistically significant ( P portal hypertension was significantly affected by spleen hardness at the 3 rd month after treatment [relative risk (RR) = 3.481]. At the 9 th month after treatment, the prognosis

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. 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? 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. 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 a need to change perception of hypertension from a gamble to a disease process. Changing the

Management of arterial hypertension in patients with acute stroke.

Adeoye, Opeolu; Jauch, Edward C

2006-11-01

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.

ARR was calculated from serum aldosterone and plasma renin concentrations. The cut-off level for ARR was 65. Patients with an increased ARR were considered for confirmatory testing with the fludrocortisone suppression test (FST), followed by adrenal computed tomographic radiology (CT) and adrenal venous sampling (AVS). Of 200 patients, 36 patients had an ARR > 65. Of these 36 patients, 11 patients had an incomplete aldosterone inhibition during FST. Three patients were diagnosed with an aldosterone producing adenoma (APA) and eight with bilateral adrenal hyperplasia (BHA). Except for moderately lower level of P-K in patients with an ARR > 65 and in patients with PA, there were no biochemical or clinical differences found among hypertensive patients with PA compared with patients without PA. Eleven of 200 evaluated patients (5.5%) were considered to have PA. The diagnosis of PA should therefore be considered in newly diagnosed hypertensive subjects and screening for the diagnosis is warranted.

To investigate whether newly diagnosed untreated hypertensive patients show higher left ventricular (LV) contractility, as assessed by traditional echocardiographic indices and carotid wave intensity (WI) parameters, including amplitude of the peak during early (W 1 ) and late systole (W 2 ). A total of 145 untreated hypertensive patients were compared with 145 age- and sex-matched normotensive subjects. They underwent comprehensive echocardiography and WI analysis. WI analysis was performed at the level of the common carotid artery. The diameter changes were the difference between the displacement of the anterior and posterior walls, with the cursors set to track the media-adventitia boundaries 2 cm proximal to the carotid bulb and calibrated by systolic and diastolic BP. Peak acceleration was derived from blood flow velocity measured by Doppler sonography with the range-gate positioned at the center of the vessel diameter. WI was based on the calculation of (dP/dt)×(dU/dt), where dP/dt and dU/dt were the derivatives of BP (P) and velocity (U) with respect to time. One-point pulse wave velocity (PWVβ) and the interval between the R wave on ECG and the first peak of WI (R-W 1 ), using a high definition echo-tracking system implemented in the ultrasound machine (Aloka), were also derived. After adjustment for body weight, heart rate, and physical activity, the two groups had similar general characteristics and diastolic function. However, hypertensives showed significantly higher LV mass, LV ejection fraction (LVEF), circumferential and LV end-systolic stress, and one-point PWV as well as W 1 (13.646 ± 7.368 vs 9.308 ± 4.675 mmHg m/s 3 , P =.001) and W 2 (4.289 ± 2.017 vs 2.995 ± 1.868 mmHg m/s 3 , P =.001). Hypertensives were divided into tertiles according to LVEF: W 1 (11.934 ± 5.836 vs 11.576 ± 5.857 vs 17.227 ± 8.889 mmHg m/s 3 , P function. © 2016 by the American Institute of Ultrasound in Medicine.

To measure azygos, portal and aortic flow by two-dimensional cine phase-contrast magnetic resonance imaging (2D-cine PC MRI), and to compare the MRI values to hepatic venous pressure gradient (HVPG) measurements, in patients with cirrhosis. Sixty-nine patients with cirrhosis were prospectively included. All patients underwent HVPG measurements, upper gastrointestinal endoscopy and 2D-cine PC MRI measurements of azygos, portal and aortic blood flow. Univariate and multivariate regression analyses were used to evaluate the correlation between the blood flow and HVPG. The performance of 2D-cine PC MRI to diagnose severe portal hypertension (HVPG ≥ 16 mmHg) was determined by receiver operating characteristic curve (ROC) analysis, and area under the curves (AUC) were compared. Azygos and aortic flow values were associated with HVPG in univariate linear regression model. Azygos flow (p portal blood flow (AUC = 0.40 (95 % CI [0.25-0.54]). 2D-cine PC MRI is a promising technique to evaluate significant portal hypertension in patients with cirrhosis. • Noninvasive HVPG assessment can be performed with MRI azygos flow. • Azygos MRI flow is an easy-to-measure marker to detect significant portal hypertension. • MRI flow is more specific that varice grade to detect portal hypertension.

Full Text Available Exercise capacity and survival of patients with IPF is potentially impaired by pulmonary hypertension. This study aims to investigate diagnostic and prognostic properties of gas exchange during exercise and lung function in IPF patients with or without pulmonary hypertension. In a multicentre setting, patients with IPF underwent right heart catheterization, cardiopulmonary exercise and lung function testing during their initial evaluation. Mortality follow up was evaluated. Seventy-three of 135 patients [82 males; median age of 64 (56; 72 years] with IPF had pulmonary hypertension as assessed by right heart catheterization [median mean pulmonary arterial pressure 34 (27; 43 mmHg]. The presence of pulmonary hypertension was best predicted by gas exchange efficiency for carbon dioxide (cut off ≥152% predicted; area under the curve 0.94 and peak oxygen uptake (≤56% predicted; 0.83, followed by diffusing capacity. Resting lung volumes did not predict pulmonary hypertension. Survival was best predicted by the presence of pulmonary hypertension, followed by peak oxygen uptake [HR 0.96 (0.93; 0.98]. Pulmonary hypertension in IPF patients is best predicted by gas exchange efficiency during exercise and peak oxygen uptake. In addition to invasively measured pulmonary arterial pressure, oxygen uptake at peak exercise predicts survival in this patient population.

The causes of pulmonary arterial hypertension (PAH) are diverse and include multiple congenital and acquired cardiac diseases as well as diseases primarily affecting the pulmonary vasculature, lung, pleura and chest wall. The traditional role of CT in evaluating PAH includes assessment of pulmonary vasculature and lung parenchyma with limited assessment of the heart. Advances in multidetector CT technology with improved spatial and temporal resolution now permit accurate delineation of cardiac morphology. CT pulmonary angiography (CTPA) is widely utilised in the workup of patients with suspected pulmonary vascular disease and can identify both pulmonary and cardiac causes. As the initial presentation for CTPA is often precipitated by nonspecific, unexplained symptoms and therefore undertaken by a general radiologist, it is important that a systematic approach to the interpretation of these studies, including cardiac evaluation, is routinely adopted. This paper reviews the CT evaluation in pulmonary hypertension with a particular focus on the cardiac causes, their subclassification into congenital systemic to pulmonary shunts and secondary to left heart disease, and their imaging features. It emphasises the use of a systematic approach to interpretation of CTPA examinations both in patients with known PAH and those with previously unsuspected disease. (orig.)

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.

Metabolic syndrome is being reported more frequently in the Eastern Mediterranean region. Patients with hypertension attending family practice clinics in the University of Jordan Hospital between February and July 2006 were assessed for the frequency of metabolic syndrome and its individual components. Of 345 patients studied, 65% had metabolic syndrome. Females were more likely to meet Adult Treatment Panel-III criteria for the diagnosis. Diabetes mellitus was the most frequent component of metabolic syndrome in males, while low serum high-density lipoprotein cholesterol and high waist circumference ranked first and second in females. Primary care providers should be alert to the importance of screening patients with hypertension for metabolic syndrome to prevent and manage these combined conditions.

The aim of this study was to interpret how hypertensive patients experience health care self-management. Hypertension is one of the most prevalent chronic diseases worldwide. The involvement of individuals in the management of their health care to treat this disease is fundamental, with aid and advice from healthcare professionals, especially nurses, so that hypertensive patients can effectively self-manage their health care. Qualitative study. Hypertensive patients were recruited using theoretical sampling. The study sample consisted of 28 hypertensive patients aged 18-59 years who were registered in the e-Health programme of the Ministry of Health. Data were collected and analyzed between September 2012-October 2014 using a semi-structured interview based on the methodological framework of the constructivist grounded theory. The participants' statements depicted an outline of their experience with the disease: the beginning of the illness; understanding the disease process; incorporating behaviour for self-management of the disease; experiencing attitudes and actions in the control and treatment of the disease; and being treated in the public healthcare system. A central phenomenon emerged, namely hypertensive patients' experience of self-management of health care. This phenomenon has paths, actions and interactions. When patients discover that they have the disease and become aware of the disease process, they assume the identity of being hypertensive and become proactive in their health care and in living with their families and in communities. © 2016 John Wiley & Sons Ltd.

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.

Full Text Available Alberto Francisco Rubio-Guerra1, Hilda Vargas-Robles2, Luz Maria Ramos-Brizuela1, Bruno Alfonso Escalante-Acosta21Metabolic Clinic, Hospital General de Ticomán SS DF, Mexico; 2Department of Molecular Biomedicine, Centro de Investigacion y de Estudios Avanzados del IPN, MexicoAbstract: Nitric oxide (NO is an important regulator of vascular tone, and is also an antithrombotic, anti-inflammatory, antiproliferative, and antiatherogenic factor. 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

Background: Atrial fibrillation (AF) is highly common, and is most frequently observed in individuals with hypertension and structural cardiac disease. Sympathetic hyperactivity plays a fundamental role in the progression, maintenance and aggravation of arrhythmia. Endurance exercise training clearly lowers sympathetic activity in sympathoexcitatory disease states, and is well-tolerated by patients with chronic kidney disease (CKD). Methods: We assessed 50 CKD patients with hypertension. Each...

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.

There is concern that performance measures, patient ratings of their care, and pay-for-performance programs may penalize healthcare providers of patients with multiple chronic coexisting conditions. We examined the impact of coexisting conditions on the quality of care for hypertension and patient perception of overall quality of their health care. We classified 141 609 veterans with hypertension into 4 condition groups: those with hypertension-concordant (diabetes mellitus, ischemic heart disease, dyslipidemia) and/or -discordant (arthritis, depression, chronic obstructive pulmonary disease) conditions or neither. We measured blood pressure control at the index visit, overall good quality of care for hypertension, including a follow-up interval, and patient ratings of satisfaction with their care. Associations between condition type and number of coexisting conditions on receipt of overall good quality of care were assessed with logistic regression. The relationship between patient assessment and objective measures of quality was assessed. Of the cohort, 49.5% had concordant-only comorbidities, 8.7% had discordant-only comorbidities, 25.9% had both, and 16.0% had none. Odds of receiving overall good quality after adjustment for age were higher for those with concordant comorbidities (odds ratio, 1.78; 95% confidence interval, 1.70 to 1.87), discordant comorbidities (odds ratio, 1.32; 95% confidence interval, 1.23 to 1.41), or both (odds ratio, 2.25; 95% confidence interval, 2.13 to 2.38) compared with neither. Findings did not change after adjustment for illness severity and/or number of primary care and specialty care visits. Patient assessment of quality did not vary by the presence of coexisting conditions and was not related to objective ratings of quality of care. Contrary to expectations, patients with greater complexity had higher odds of receiving high-quality care for hypertension. Subjective ratings of care did not vary with the presence or absence of

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.

The objectives of this clinical study using iodine-123 metaiodobenzylguanidine (MIBG) scintigraphy were (a) to evaluate cardiac sympathetic denervation in non-insulin-dependent diabetes mellitus (NIDDM) patients with and without hypertension and (b) to investigate the relation between cardiac sympathetic denervation and prognosis in NIDDM patients. We compared clinical characteristics and MIBG data [heart to mediastinum (H/M) ratio and % washout rate (WR)] in a control group and NIDDM patients with and without hypertension. MIBG scintigraphy was performed in 11 controls and 82 NIDDM patients without overt cardiovascular disease except for hypertension (systolic blood pressure ≥140 and/or diastolic blood pressure ≥90 mmHg). After MIBG examination, blood pressure was measured regularly in all NIDDM patients. There were significant differences between 65 normotensive and 17 hypertensive NIDDM patients with respect to age (55±11 vs 63±12 years, respectively, P<0.05), prevalence of diabetic retinopathy (12% vs 35%, respectively, P<0.05) and systolic blood pressure (120±12 vs 145±16 mmHg, respectively, P<0.001). The H/M ratio in hypertensive NIDDM patients was significantly lower than in the control group (1.81±0.29 vs 2.27±0.20, respectively, P<0.01). During the follow-up period (18± 12 months), 17 NIDDM patients newly developed hypertension after MIBG examination. There were no significant differences in their clinical characteristics compared with persistently normotensive or hypertensive NIDDM patients. %WR in patients with new onset hypertension was significantly higher than in the control group (30.88%±16.87% vs 12.89%±11.94%, respectively, P<0.05). Moreover, in these patients %WR correlated with duration from the date of MIBG scintigraphy to the onset of hypertension (r=-0.512, P<0.05). Five NIDDM patients died during the follow-up period (four newly hypertensive patients and one normotensive patient). There were significant statistical differences

Contrast induced nephropathy (CIN) is the third lead cause of hospital acquired renal failure and was associated with significant morbidity and mortality. We hypothesized that hypertension is an independent risk factor for the development of CIN in patients undergoing elective percutaneous coronary intervention (PCI). The case-control method was used, 138 patients scheduled for elective PCI. We measured serum creatinine at baseline and after 24 hours of the procedure. CIN was defined as arising in serum creatinine of at least 44 μmol/l (0,5 mg/dl) or 25% rise from baseline. All patients received low osmolality nonionic contrast during PCI. Hypertension was defined as self-reported a history of treated or untreated diagnosed high blood pressure. One hundred thirty-eight patients (74,6%) were male, and 35 patients (25,4%) were female. Among the 138 patients, 86 (62,3%) were hypertensive patients whereas 52 (37,7%) were nonhypertensive patients. There was no difference in baseline serum creatinine levels and the amount of contrast media in patient with and without CIN. CIN developed in 42 patients, 39 patients (92,9%) were hypertensive compared to 3 patients (7,1%) without hypertension with p value < 0,05. (Odds ratio 16,8, 95% CI 4.542 - 62,412). This study showed that hypertension was a risk factor for the development of CIN

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

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

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

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.

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 a need to change perception

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.

Resistant hypertension, the inability to achieve goal blood pressure despite the use of three or more appropriately dosed antihypertensive drugs (including a diuretic), remains a common clinical problem, especially in patients with chronic kidney disease (CKD). While the exact prevalence and prognosis of resistant hypertension in CKD patients remain unknown, resistant hypertension likely contributes significantly to increased cardiovascular risk and progression of kidney disease in this population. We review the identification and evaluation of patients with resistant hypertension, including the importance of 24-h ambulatory blood pressure monitoring in the identification of 'white-coat', 'masked' and 'non-dipper' hypertension, the latter of which has particular clinical and therapeutic importance in patients with resistant hypertension and CKD. We then discuss treatment strategies for resistant hypertension that target the pathophysiologic mechanisms underlying resistance to treatment, including persistent volume excess, incomplete renin-angiotensin-aldosterone system blockade and inadequate nocturnal blood pressure control. Finally, we propose a treatment algorithm for evaluation and treatment of resistant hypertension in patients with CKD. © The Author 2013. Published by Oxford University Press on behalf of ERA-EDTA.

To assess the effectiveness of mailed hypertension educational materials. Prospective, randomized, controlled single-blind trial. Primary care practice-based research network in which 9 clinics located in Portland, Oregon participated. Patients with mildly uncontrolled hypertension as defined as a last blood pressure of 140 to 159/90 to 99 mmHg from query of an electronic medical record database. Patients randomized to intervention were mailed 2 educational packets approximately 3 months apart. The first mailer included a letter from each patient's primary care provider. The mailer included a booklet providing an overview of hypertension and lifestyle modification and a refrigerator magnet noting target blood pressure. The second mailing also included a letter from the patient's primary care provider, a second educational booklet focused on medication compliance and home blood pressure monitoring, and a blood pressure logbook. The control group consisted of similar patients receiving usual care for hypertension. Patients from each group were randomly selected for invitation to participate in a study visit to measure blood pressure and complete a survey (intervention n= 162; control n= 150). No significant difference was found in mean blood pressure between intervention and control patients (135/77 mmHg vs 137/77 mmHg; P=.229). Patients in the intervention arm scored higher on a hypertension knowledge quiz (7.48 +/- 1.6 vs 7.06 +/- 1.6; P=.019), and reported higher satisfaction with several aspects of their care. No significant difference was seen in the prevalence of home blood pressure monitoring ownership or use. In patients with mildly uncontrolled hypertension, educational mailers did not yield a significant decrease in blood pressure. However, significant improvement in patient knowledge, frequency of home monitoring, and satisfaction with care were demonstrated.

The clinical relevance of ambulatory blood pressure monitoring (ABPM) for risk stratification in renal transplant patients still remains poorly defined. We investigated the association between clinic and ABPM with an established biomarker of atherosclerosis (intima-media thickness [IMT] by echo-color Doppler) in a large, inclusive survey (n = 172) in renal transplant patients at a single institution. Forty-two patients (24%) were classified as hypertensive by ABPM criteria and 29 (17%) by clinic blood pressure (BP) criteria. Average daytime and nighttime BP was 126 ± 12/78 ± 9 mm Hg and 123 ± 13/74 ± 10 mm Hg, respectively. Forty-five patients (26%) were classified as hypertensive by the daytime criterion (>135/85 mm Hg) and a much higher proportion (n = 119, 69%) by the nighttime criterion (>120/70 mm Hg). Sixty-two patients (36%) had a night-day ratio of 1 or greater, indicating clear-cut nondipping. The average nighttime systolic BP (r = 0.24, P = 0.001) and the night-day systolic BP ratio (r = 0.23, P = 0.002) were directly related to IMT, and these associations were much more robust than the 24-hour systolic BP-IMT relationship (r = 0.16, P = 0.04). Average daytime BP and clinic B were unrelated to IMT. In a multiple regression analysis adjusting for confounders, the night-day systolic BP ratio maintained an independent association with IMT (β = 0.14, P = 0.04). In renal transplant patients, the prevalence of nocturnal hypertension by far exceeds the prevalence of hypertension as assessed by clinic, daytime, and 24-hour ABPM. Nighttime systolic BP and the night-day ratio but no other BP metrics are independently associated with IMT. Blood pressure during nighttime may provide unique information for the assessment of cardiovascular risk attributable to BP burden in renal transplant patients.

Sexual function in hypertensive patients receiving treatment

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

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.

Background Hypertension control is a challenge globally. Barriers to optimal control exist at the patient, physician, and health system levels. Patient-related barriers in our environment are not clear. The aim of this study was to identify patient-related barriers to control of hypertension among adults with hypertension in a semiurban community in South-East Nigeria. Methods This was a cross-sectional descriptive study of patients with a diagnosis of hypertension and on antihypertensive medication. Results A total of 252 participants were included in the survey, and comprised 143 males (56.7%) and 109 females (43.3%). The mean age of the participants was 56.6±12.7 years, with a diagnosis of hypertension for a mean duration of 6.1±3.3 years. Among these patients, 32.9% had controlled blood pressure, while 39.3% and 27.8%, respectively, had stage 1 and stage 2 hypertension according to the Seventh Report of the Joint National Committee on Prevention, Detection and Evaluation of High Blood Pressure. Only 23.4% knew the consequences of poor blood pressure control and 64% were expecting a cure from treatment even when the cause of hypertension was not known. Furthermore, 68.7% showed low adherence to medication, the reported reasons for which included forgetfulness (61.2%), financial constraints (56.6%), high pill burden (22.5%), side effects of medication (17.3%), and low measured blood pressure (12.1%). Finally, knowledge and practice of the lifestyle modifications necessary for blood pressure control was inadequate among the participants. Conclusion Poor knowledge regarding hypertension, unrealistic expectations of treatment, poor adherence with medication, unawareness of lifestyle modification, and failure to apply these were identified as patient-related barriers to blood pressure control in this study.

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.

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 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.

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.

We build classification models and risk assessment tools for diabetes, hypertension and comorbidity using machine-learning algorithms on data from Kuwait. We model the increased proneness in diabetic patients to develop hypertension and vice versa. We ascertain the importance of ethnicity (and natives vs expatriate migrants) and of using regional data in risk assessment. Retrospective cohort study. Four machine-learning techniques were used: logistic regression, k-nearest neighbours (k-NN), multifactor dimensionality reduction and support vector machines. The study uses fivefold cross validation to obtain generalisation accuracies and errors. Kuwait Health Network (KHN) that integrates data from primary health centres and hospitals in Kuwait. 270 172 hospital visitors (of which, 89 858 are diabetic, 58 745 hypertensive and 30 522 comorbid) comprising Kuwaiti natives, Asian and Arab expatriates. Incident type 2 diabetes, hypertension and comorbidity. Classification accuracies of >85% (for diabetes) and >90% (for hypertension) are achieved using only simple non-laboratory-based parameters. Risk assessment tools based on k-NN classification models are able to assign 'high' risk to 75% of diabetic patients and to 94% of hypertensive patients. Only 5% of diabetic patients are seen assigned 'low' risk. Asian-specific models and assessments perform even better. Pathological conditions of diabetes in the general population or in hypertensive population and those of hypertension are modelled. Two-stage aggregate classification models and risk assessment tools, built combining both the component models on diabetes (or on hypertension), perform better than individual models. Data on diabetes, hypertension and comorbidity from the cosmopolitan State of Kuwait are available for the first time. This enabled us to apply four different case-control models to assess risks. These tools aid in the preliminary non-intrusive assessment of the population. Ethnicity is seen significant

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.

This study examined in vivo (1) skeletal muscle oxygenation and microvascular function, at rest and during handgrip exercise, and (2) their association with macrovascular function and exercise blood pressure (BP), in newly diagnosed, never-treated patients with hypertension and normotensive individuals. Ninety-one individuals (51 hypertensives and 40 normotensives) underwent office and 24-hour ambulatory BP, arterial stiffness, and central aortic BP assessment, followed by a 5-minute arterial occlusion and a 3-minute submaximal handgrip exercise. Changes in muscle oxygenated and deoxygenated hemoglobin and tissue oxygen saturation were continuously monitored by near-infrared spectroscopy and beat-by-beat BP by Finapres. Hypertensives had higher ( P age and body mass index (BMI) adjusted). When exercising at the same submaximal intensity, hypertensives required a significantly greater ( P hypertension exhibit prominent reductions in in vivo indices of skeletal muscle oxidative capacity, suggestive of mitochondrial dysfunction, and blunted muscle microvascular reactivity. These dysfunctions were associated with higher aortic systolic BP and arterial stiffness. Dysregulations in muscle oxygen delivery/utilization and microvascular stiffness, in hypertensive patients, partially contribute to their exaggerated BP during exercise. © 2017 American Heart Association, Inc.

Several factors and conditions interfering with blood pressure (BP control, such as excess sodium intake, obesity, diabetes, older age, kidney disease, and certain identifiable causes of hypertension are common in patients resistant to antihypertensive treatment. Arterial stiffness, measured by brachial-ankle pulse wave velocity (baPWV, is increasingly recognized as an important prognostic index and potential therapeutic target in hypertensive patients. The aim of this study was to determine whether there is an association between RH and arterial stiffness. Methods: This study included 1,620 patients aged ≥65 years who were referred or self-referred to the outpatient hypertension unit located at a single cardiovascular center. They were separated into normotensive, controlled BP, and resistant hypertension groups. Home BP, blood laboratory parameters, echocardiographic studies and baPWV all were measured. Results: The likelihood of diabetes mellitus was significantly greater in the RH group than in the group with controlled BP (odds ratio 2.114, 95% confidence interval [CI] 1.194–3.744, P=0.010. Systolic BP was correlated in the RH group significantly more than in the group with controlled BP (odds ratio 1.032, 95% CI 1.012–1.053, P=0.001. baPWV (odds ratio 1.084, 95% CI 1.016–1.156, P=0.015 was significantly correlated with the presence of RH.

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

Clinical role of non-invasive assessment of portal hypertension.

Measurement of portal pressure is pivotal in the evaluation of patients with liver cirrhosis. The measurement of the hepatic venous pressure gradient represents the reference method by which portal pressure is estimated. However, it is an invasive procedure that requires significant hospital resources, including experienced staff, and is associated with considerable cost. Non-invasive methods that can be reliably used to estimate the presence and the degree of portal hypertension are urgently needed in clinical practice. Biochemical and morphological parameters have been proposed for this purpose, but have shown disappointing results overall. Splanchnic Doppler ultrasonography and the analysis of microbubble contrast agent kinetics with contrast-enhanced ultrasonography have shown better accuracy for the evaluation of patients with portal hypertension. A key advancement in the non-invasive evaluation of portal hypertension has been the introduction in clinical practice of methods able to measure stiffness in the liver, as well as stiffness/congestion in the spleen. According to the data published to date, it appears to be possible to rule out clinically significant portal hypertension in patients with cirrhosis ( i.e ., hepatic venous pressure gradient ≥ 10 mmHg) with a level of clinically-acceptable accuracy by combining measurements of liver stiffness and spleen stiffness along with Doppler ultrasound evaluation. It is probable that the combination of these methods may also allow for the identification of patients with the most serious degree of portal hypertension, and ongoing research is helping to ensure progress in this field.

Full Text Available Background: Many patients with suspected acute myocardial infarction (AMI and eligible for thrombolytic therapy may not be treated because of association between hemorrhagic complications especially intracranial hemorrhage (ICH, and severe hypertension (HTN at presentation. Unfortunately, this leads to under use or delay in thrombolytic therapy. We assessed effect of decreasing elevated blood pressure before thrombolytic therapy in order to reduce the incidence of ICH without increasing mortality rate. Methods: This observational and analytical cohort study enrolled 293 patients (215males and 78 female with STsegment elevation (AMI that were hospitalized in emergency department of Noor hospital, Isfahan, Iran. Severe hypertension (blood pressure ≥180/110mmHg was diagnosed in 132 patients. All of them received 1.5 million units streptokinase within one hour intravenously. In the hypertensive group, elevated blood pressure was lowered to less than180/110mmhg before thrombolysis and they were observed to detect development of symptomatic ICH and they underwent Brain CT scan, if required. Results: The incidence of total stroke, ICH and death were 1.4%, 0.7% and 4.8%, respectively. The incidence of death and ICH in patients with severe hypertension was less than control group (P value=0.13 and 0.59, respectively Conclusion: Although we did not find any increase in ICH incidence in severe hypertensive patients treated be streptokinase due to AMI, but we recommend a multi-centric study with more cases and varied thrombolytic protocols.

Studies in hypertension (HTN) pharmacogenomics seek to identify genetic sources of variable antihypertensive drug response. Genetic association studies have detected single-nucleotide polymorphisms (SNPs) that link to drug responses; however, to understand mechanisms underlying how genetic traits alter drug responses, a biological interface is needed. Patient-derived induced pluripotent stem cells (iPSCs) provide a potential source for studying otherwise inaccessible tissues that may be important to antihypertensive drug response. The present study established multiple iPSC lines from an HTN pharmacogenomics cohort. We demonstrated that established HTN iPSCs can robustly and reproducibly differentiate into functional vascular smooth muscle cells (VSMCs), a cell type most relevant to vasculature tone control. Moreover, a sensitive traction force microscopy assay demonstrated that iPSC-derived VSMCs show a quantitative contractile response on physiological stimulus of endothelin-1. Furthermore, the inflammatory chemokine tumor necrosis factor α induced a typical VSMC response in iPSC-derived VSMCs. These studies pave the way for a large research initiative to decode biological significance of identified SNPs in hypertension pharmacogenomics. Treatment of hypertension remains suboptimal, and a pharmacogenomics approach seeks to identify genetic biomarkers that could be used to guide treatment decisions; however, it is important to understand the biological underpinnings of genetic associations. Mouse models do not accurately recapitulate individual patient responses based on their genetics, and hypertension-relevant cells are difficult to obtain from patients. Induced pluripotent stem cell (iPSC) technology provides a great interface to bring patient cells with their genomic data into the laboratory and to study hypertensive responses. As an initial step, the present study established an iPSC bank from patients with primary hypertension and demonstrated an effective

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

A comparative analysis of pulmonary perfusion scanning through cardiac catheterization of 57 patients including 32 patients with congenital heart disease, 8 patients with chronic pulmonary thromboembolism and 7 patients with primary pulmonary hypertension is reported. The lung scintigram obtained with In-113m or Tc-99m-MAA represents the distribution of pulmonary blood. It has been found that the lung scintigram was abnormal in patients of congenital heart disease with pulmonary hypertension (i. e. pulmonary artery pressure between 41-80 mmHg) and the extent of radoiactive regional defects is proportional to the level of pulmonary hypertension. The results of the analysis indicated that pulmonary perfusion scanning being a noninvasive technique would be a useful method in evaluating the level of pulmonary hypertension in patients with left to right shunt before and after surgical operation

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.

Hypertension is a major modifiable risk factor for cardiovascular and kidney disease, yet the proportion of adults whose hypertension is controlled is low. The patient-centered medical home (PCMH) is a model for care delivery that emphasizes patient-centered and team-based care and focuses on quality and safety. Our goal was to investigate changes in hypertension care under PCMH implementation in a large multipayer PCMH demonstration project that may have led to improvements in hypertension control. The PCMH transformation initiative conducted 118 semistructured interviews at 17 primary care practices in southeastern Pennsylvania between January 2011 and January 2012. Clinicians (n = 47), medical assistants (n = 26), office administrators (n = 12), care managers (n = 11), front office staff (n = 7), patient educators (n = 4), nurses (n = 4), social workers (n = 4), and other administrators (n = 3) participated in interviews. Study personnel used thematic analysis to identify themes related to hypertension care. Clinicians described difficulties in expanding services under PCMH to meet the needs of the growing number of patients with hypertension as well as how perceptions of hypertension control differed from actual performance. Staff and office administrators discussed achieving patient-centered hypertension care through patient education and self-management support with personalized care plans. They indicated that patient report cards were helpful tools. Participants across all groups discussed a team- and systems-based approach to hypertension care. Practices undergoing PCMH transformation may consider stakeholder perspectives about patient-centered, team-based, and systems-based approaches as they work to optimize hypertension care.

Full Text Available Introduction. Uncontrolled hypertension is observed in 65-92% of hypertensive patients. It plays an important role in the development of adverse cardiovascular events and survival, which depend on subclinical target organ damage. There are reports on the relationship between ineffective hypertension control and left ventricular (LV hypertrophy or large arteries stiffness. However, the nature of the remodeling in uncontrolled hypertension remains poorly understood. Objective: to study the character and relationship of left ventricular and arterial remodeling depending on effectiveness of hypertension control. Design and method. We performed a study of 363 hypertensive patients (160 men and 203 women aged 50,8 ± 1,2 years without comorbidities, which were divided into 3 groups according to the effectiveness of blood pressure (BP control: 160 patients with controlled hypertension, 142 patients with uncontrolled hypertension and 61 patients with resistant hypertension. Uncontrolled BP based on measured systolic BP≥140 mmHg and diastolic BP≥90 mmHg. Remodeling indexes of left ventricular, elastic (common carotid and muscular (brachial artery were evaluated by the ultrasonic method. The severity and character of diastolic dysfunction, hypertrophy, types of remodeling and stiffness were assessed. Statistical processing of the results was performed using Student's t criterion and Pearson correlation analysis. Results and discussion. According to the results of the study, uncontrolled hypertension affected the development of subclinical cardiovascular lesions negatively. Thus, LV hypertrophy was detected more frequently in the third group (91,8% in resistant hypertension versus 46,8% in controlled hypertension, p<0,05. Differences in LV geometry with increasing of concentric remodeling types were also observed more frequently in the third group, where concentric remodeling and concentric hypertrophy types were founded in 14,8% and 59

Anticoagulation is a common treatment modality in patients with pulmonary arterial hypertension (PAH). Further studies are needed to appropriately assess the risk/benefit ratio of anticoagulation, particularly in PAH patients receiving PAH-specific therapies. We use observational long-term data on PAH patients treated with subcutaneous (SQ) treprostinil from a large open-label study. Patients were followed for up to 4 years. The use of warfarin and bleeding events were recorded. At total of 860 patients (age [mean±SD] 46±15 years, 76% female, 83% Caucasian, 49% idiopathic PAH, and 76% New York Heart Association [NYHA] functional class III) were included. All patients received SQ treprostinil (15% also other pulmonary hypertension [PH]-therapies) and 590 (69%) received warfarin during the study. The proportions of women, African American, and idiopathic pulmonary hypertension (IPAH) patients were higher in the group receiving warfarin. A higher proportion of patients with congenital heart disease and portopulmonary hypertension did not receive warfarin. There were no differences in unadjusted long-term survival between PAH patients receiving warfarin or not (log-rank test, P value=.69), even when only considering idiopathic PAH (P=.32). In addition, no difference was found in adjusted long-term survival both in PAH (P=.84) and idiopathic PAH patients (P=.44) based on the use of warfarin. Furthermore, no survival difference based on the use of warfarin were noted between propensity score-matched PAH patients (P=.37). Long-term anticoagulation with warfarin was not associated with any significant effect on survival in PAH or idiopathic PAH patients treated with SQ treprostinil. © 2017 John Wiley & Sons Ltd.

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

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

Full Text Available In hypertensive patients, a negative self-concept (body-image, self- ideal, self-esteem, self-role and self-identity will trigger a depression. The purpose of this study was to analyze the relationship between self-concept with the degree of depression in hypertensive patients at the Masalle Community Health Center, Masalle Sub District, Enrekang District. The subjects of this cross sectional study were 71 hypertensive patients selected by purposive sampling technique. Data were collected through questionnaire, then analyzed descriptively in the form of frequency and percentage, then continued with Chi square test, and ended with multiple linear regression test. The results of data analysis show that body-image and self-esteem is associated with the degree of depression in hypertensive patients.

The purpose of this study was to assess the value of morphometric data on conventional radiography and CT predicting the presence and degree of pulmonary hypertension and to assess the reversibility after surgery. On preoperative X-ray films and CT scans of 50 patients with pulmonary hypertension secondary to chronic thromboembolism, we measured the cardiothoracic ratio, basal diameter, length of cardiac contact to sternum, pulmonary trunk, right and left descending pulmonary artery, and the septum angle. These data were correlated with pulmonary arterial pressure. In 14 X-ray patients and 18 CT patients, with follow-up after surgical thromboendarterectomy the reversibility of these changes was assessed. A dilated pulmonary trunk was the most common abnormality (96% each on X-ray and CT). Pulmonary arteries were dilated on X-ray in 40% (right) and 14% (left), and on CT in 92% (right) and 96% (left). The best correlation with mean arterial pressure was found measuring the pulmonary trunk on CT (r=0.43, p<0.01). After surgery, reversibility was most significant for the pulmonary trunk on CT (p<0.0001). In patients with chronic pulmonary embolism, pulmonary hypertension can best be predicted by assessing the diameter of the pulmonary trunk both on X-ray and CT. No close correlation is present between the extent of any parameter and the level of the pulmonary pressure. (orig.)

Catheter-based renal sympathetic denervation (RD) causes significant blood pressure (BP) reductions in patients with resistant hypertension (rHTN). However, hypertensive elderly patients reportedly have a lower sympathetic tone than younger patients and a BP lowering effect of RD in this population has not yet been demonstrated. The purpose of this study was to assess the efficacy and safety of RD in elderly patients. We reviewed all consecutive patients aged ≥ 75 years (mean: 78 years) with rHTN treated with RD. Twenty-four patients were included in this prospective study. Office and ambulatory BPs were assessed at baseline and 6-months follow-up. Primary endpoint was the change in office systolic BP at 6 months. Baseline mean office BP was 173/86 ± 21/13 mm Hg. Baseline 24-hr mean ambulatory BP, available in 22 patients, was 158/80 ± 20/13 mm Hg. Baseline creatinine was 1.0 ± 0.18 mg/dl and mean number of antihypertensive agents at baseline 4.3 ± 1.4. No device- or procedure-related adverse events occurred. At 6-months follow-up, the mean office BP decreased by 19/11 ± 29/16 mm Hg (P renal function was not impaired. According to our findings, a similar magnitude of BP reduction as reported in previous trials can be expected in elderly patients. Elderly patients with rHTN should not be excluded from renal denervation. © 2015 Wiley Periodicals, Inc.

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.

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.

The possibility of developing idiopathic portal hypertension has been described with thiopurine treatment despite compromises the prognosis of these patients, the fact its true prevalence is unknown. A cross-sectional study was conducted in a cohort of inflammatory bowel disease (IBD) patients followed at our unit, to determine the prevalence of diagnosis of idiopathic portal hypertension (IPH) and its relationship with thiopurine treatment. At the time of the analysis, 927/1,419 patients were under treatment with thiopurine drugs (65%). A total of 4 patients with IBD type Crohn's disease with idiopathic portal hypertension probably related to the thiopurine treatment were identified (incidence of 4.3 cases per 1,000). Seventy-five percent of patients started with signs or symptoms of portal hypertension. Only one patient was asymptomatic but the diagnosis of IPH because of isolated thrombocytopenia is suspected. However, note that all patients had thrombocytopenia previously. Abdominal ultrasound with fibroscan, hepatic vein catheterization and liver biopsy were performed on all of them as part of the etiology of portal hypertension. In the abdominal ultrasound, indirect portal hypertension data were observed in all patients (as splenomegaly) cirrhosis was also ruled out. The fibroscan data showed significant liver fibrosis (F2-F3). Idiopathic portal hypertension following thiopurine treatment in IBD patients is a rare occurrence, but it must be borne in mind in the differential diagnosis for early diagnosis, especially in patients undergoing thiopurine treatment over a long period. The presence of thrombocytopenia is often the only predictor of its development in the preclinical stage.

To evaluate arterial stiffness in hypertensive patients and to identify predictors of increased arterial stiffness. 798 hypertensives identifyed in SEPHAR II survey (mean age 51.46 ± 5.82 years; 48.1% females) were evaluated by a study questionnaire, blood pressure and antropometric measurements and laboratory work-up. Studied parameters definitions were: increased arterial stiffness: PWVao > 10m/s, visceral obesity: waist circumference >102 cm in men and > 88 cm in women, diabetes mellitus assessed by current ADA criteria, lipid dissorders by NCEP ATPIII recomendations and increased BP variability: mean SBP' standard deviation (s.d.) values above the 75th percentile. Subclinical organ damage definitions were: left ventricular hypertrophy (LVH) on ECG assessed by Cornell product,urinary albumin to creatinine ratio (UACR) of 30 - 300 mg/g) and eGFRCKD-EPI 10m/s. Regression analysis validated as predictors of increased PWVao: age group [OR: 5.53; 95%CI (2.62-13.21)], hypertrygliceridemia [OR: 1.82; 95%CI (1.18-2.81)], low-HDL cholesterol [OR: 1.62; 95%CI (1.05-2.49)], SBP's.d values above 8,49mmHg [OR: 2.14; 95%CI (1.16-3.95)], UACR 30-300 mg/g [OR: 3.46; 95%CI (1.43-8.36)], LVH on ECG [OR: 2.14; 95%CI (1.79-7.34)], eGRFCKD-EPI dislipidemia, increased SBP variability, the lack of optimal BP treatment control and the presence of subclinical organ damage, may be considered as predictors of an increased arterial stiffness in hypertensive patients, placing these patients at an increased risk of major CV events.

Endothelial dysfunction plays a major role in cardiovascular diseases and pulse amplitude tonometry (PAT) offers a non-invasive way to assess endothelial dysfunction. However, data about the reliability of PAT in cardiovascular patient populations are scarce. Thus, we evaluated the test-retest reliability of PAT using the natural logarithmic transformed reactive hyperaemia index (LnRHI). Our cohort consisted of 91 patients (mean age: 65±9.7 years, 32% female), who were divided into four groups: those with heart failure with preserved ejection fraction (HFpEF) ( n=25), heart failure with reduced ejection fraction (HFrEF) ( n=22), diabetic nephropathy ( n=21), and arterial hypertension ( n=23). All subjects underwent two separate PAT measurements at a median interval of 7 days (range 4-14 days). LnRHI derived by PAT showed good reliability in subjects with diabetic nephropathy (intra-class correlation (ICC) = 0.863) and satisfactory reliability in patients with both HFpEF (ICC = 0.557) and HFrEF (ICC = 0.576). However, in subjects with arterial hypertension, reliability was poor (ICC = 0.125). We demonstrated that PAT is a reliable technique to assess endothelial dysfunction in adults with diabetic nephropathy, HFpEF or HFrEF. However, in subjects with arterial hypertension, we did not find sufficient reliability, which can possibly be attributed to variations in heart rate and the respective time of the assessments.

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.

The association between hypertensive pregnancy disorders and cardiovascular disease later in life is well described. In this study we aim to develop a prognostic model from patients characteristics known before, early in, during and after pregnancy to identify women at increased risk of cardiovascular disease e.g. chronic hypertension years after pregnancy complicated by hypertension at term. We included women with a history of singleton pregnancy complicated by hypertension at term. Women using antihypertensive medication before pregnancy were excluded. We measured hypertension in these women more than 2years postpartum. Different patients characteristics before, early in, during and after pregnancy were considered to develop a prognostic model of chronic hypertension at 2-years. These included amongst others maternal age, blood pressure at pregnancy intake and blood pressure six weeks post-partum. Univariable analyses followed by a multivariable logistic regression analysis was performed to determine which combination of predictors best predicted chronic hypertension. Model performance was assessed by calibration (graphical plot) and discrimination (area under the receiver operating characteristic (AUC)). Of the 305 women in who blood pressure 2.5years after pregnancy was assessed, 105 women (34%) had chronic hypertension. The following patient characteristics were significant associated with chronic hypertension: higher maternal age, lower education, negative family history on hypertensive pregnancy disorders, higher BMI at booking, higher diastolic blood pressure at pregnancy intake, higher systolic blood pressure during pregnancy and higher diastolic blood pressure at six weeks post-partum. These characteristics were included in the prognostic model for chronic hypertension. Model performance was good as indicated by good calibration and good discrimination (AUC; 0.83 (95% CI 0.75 - 0.92). Chronic hypertension can be expected from patient characteristics

With the wide application of targeted drug therapies, the relevance of prognostic and predictive markers in patient selection has become increasingly important. Bevacizumab is commonly used in combination with chemotherapy in the treatment of metastatic colorectal cancer. However, there are currently no predictive or prognostic biomarkers for bevacizumab. Several clinical studies have evaluated bevacizumab-induced hypertension in patients with metastatic colorectal cancer. This meta-analysis was performed to better determine the association of bevacizumab-induced hypertension with outcome in patients with metastatic colorectal cancer, and to assess whether bevacizumab-induced hypertension can be used as a prognostic factor in these patients. We performed a systematic review and meta-analysis on seven published studies to investigate the relationship between hypertension and outcome of patients with metastatic colorectal cancer treated with bevacizumab. Our primary endpoint was progression-free survival (PFS). Secondary endpoints were overall survival (OS) and overall response rate (ORR). Hazard ratios (HRs) for PFS and OS were extracted from each trial, and the log of the relative risk ratio (RR) was estimated for ORR. The occurrence of bevacizumab-induced hypertension in patients was highly associated with improvements in PFS (HR = 0.57, 95% CI: 0.46-0.72; P hypertension. Bevacizumab-induced hypertension may represent a prognostic factor in patients with metastatic colorectal cancer.

Persistently elevated blood pressure (BP) is a leading risk factor for cardiovascular disease development, making effective hypertension management an issue of considerable public health importance. Hypertension is particularly prominent among African Americans, who have higher disease prevalence and consistently lower BP control than Whites and Hispanics. Emergency departments (ED) have limited resources for chronic disease management, especially for under-served patients dependent upon the ED for primary care, and are not equipped to conduct follow-up. Kiosk-based patient education has been found to be effective in primary care settings, but little research has been done on the effectiveness of interactive patient education modules as ED enhanced discharge for an under-served urban minority population. Achieving Blood Pressure Control Through Enhanced Discharge (AchieveBP) is a behavioral RCT patient education intervention for patients with a history of hypertension who have uncontrolled BP at ED discharge. The project will recruit up to 200 eligible participants at the ED, primarily African-American, who will be asked to return to a nearby clinical research center for seven, thirty and ninety day visits, with a 180 day follow-up. Consenting participants will be randomized to either an attention-control or kiosk-based interactive patient education intervention. To control for potential medication effects, all participants will be prescribed similar, evidenced-based anti-hypertensive regimens and have their prescription filled onsite at the ED and during visits to the clinic. The primary target endpoint will be success in achieving BP control assessed at 180 days follow-up post-ED discharge. The secondary aim will be to assess the relationship between patient activation and self-care management. The AchieveBP trial will determine whether using interactive patient education delivered through health information technology as ED enhanced discharge with subsequent

Gastrointestinal Bleeding in Cirrhotic Patients with Portal Hypertension

Biecker, Erwin

2013-01-01

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

Hypertensive left ventricular hypertrophy (H-LVH) is a potentially modifiable vascular risk factor (VRF) often overlooked in clinical practice. We aimed to evaluate the frequency of H-LVH in patients with coronary heart disease (CHD) or ischemic stroke (IS). We retrospectively assessed all the echocardiography studies of patients admitted with the diagnosis CHD or IS over a 4-year period. We studied 533 patients, 330 with CHD and 203 with IS. Mean age was 69 (±11) years, 61.5% males. Hypertension was the most common RF: 362 patients (67.9%) (CHD vs. IS: 70 vs. 64.5%; P=NS). H-LVH was seen in 234 patients (43.9%) (CHD vs. IS: 44.8 vs. 42.3%; P=NS). Patients with H-LVH were older and received a greater number of antihypertensive drugs at discharge. Half of patients with hypertension presented H-LVH (184 patients; 50.8%), with similar frequency in both groups (CHD vs. IS: 50.6 vs. 51.1%; P=NS). Neither patients' characteristics nor VRF with the exception of hypertension (P=.0001) were associated with H-LVH. H-LVH is a major VRF in patients with ischemic events in the heart and brain. Nearly half the patients present H-LVH, with a similar frequency in both groups. It is important to identify H-LVH in these patients to optimize treatment and improve long-term prognosis.

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.

Control group included 36 patients. They were not diagnosed with hypertension at the time of examination. One hundred and five patients were examined using a 4-slice CT scanner (Toshiba Asteion 4, Toshiba Medical System, Japan), and 29 patients were examined using a 128-slice scanner (Siemens Definition AS+, Siemens Healthcare, Germany) with an injection system. We used iodine-containing contrast agents such as iodixanol and iopromide for angiography. Anatomical and topographic changes of cerebral vessels were most frequently found in hypertensive patients with high and very high total cardiovascular risk. Narrowing of vertebral vessels was the most common change (27 patients (27.55%), 21 patients (21.43%) had narrowing of the right artery, and 6 (6.12%) subjects – of the left one). Tortuous course of internal carotid arteries at the neck level was visualized in 11 patients (11.22%). Narrowing of A1 segment of anterior cerebral artery was noted in 9 patients (9.18%), of the right one – in 8 patients (8.16%), of the left one – in 1 patient (1.02%). Aneurysmal dilation of intracranial vessels was visualized in 6 patients (6.12%). Saccular aneurysm of left internal carotid artery was diagnosed in 2 patients (2.04%), one patient (1.02%) had right internal carotid artery aneurysm and one patient (1.02%) had an aneurysm of the basilar artery. the most common changes of cerebral vessels diagnosed in MDCTA among patients with hypertension included various degrees of narrowing of vertebral vessels, anterior

Erythroid-specific transcriptional changes in PBMCs from pulmonary hypertension patients.

Full Text Available Gene expression profiling of peripheral blood mononuclear cells (PBMCs is a powerful tool for the identification of surrogate markers involved in disease processes. The hypothesis tested in this study was that chronic exposure of PBMCs to a hypertensive environment in remodeled pulmonary vessels would be reflected by specific transcriptional changes in these cells.The transcript profiles of PBMCs from 30 idiopathic pulmonary arterial hypertension patients (IPAH, 19 patients with systemic sclerosis without pulmonary hypertension (SSc, 42 scleroderma-associated pulmonary arterial hypertensio patients (SSc-PAH, and 8 patients with SSc complicated by interstitial lung disease and pulmonary hypertension (SSc-PH-ILD were compared to the gene expression profiles of PBMCs from 41 healthy individuals. Multiple gene expression signatures were identified which could distinguish various disease groups from controls. One of these signatures, specific for erythrocyte maturation, is enriched specifically in patients with PH. This association was validated in multiple published datasets. The erythropoiesis signature was strongly correlated with hemodynamic measures of increasing disease severity in IPAH patients. No significant correlation of the same type was noted for SSc-PAH patients, this despite a clear signature enrichment within this group overall. These findings suggest an association of the erythropoiesis signature in PBMCs from patients with PH with a variable presentation among different subtypes of disease.In PH, the expansion of immature red blood cell precursors may constitute a response to the increasingly hypoxic conditions prevalent in this syndrome. A correlation of this erythrocyte signature with more severe hypertension cases may provide an important biomarker of disease progression.

Prognostic factors in pulmonary arterial hypertension: assessing the course of the disease

Full Text Available The practical management of pulmonary arterial hypertension (PAH requires an accurate assessment of disease severity and prognosis. A number of prognostic indicators are known to be associated with patient outcome, and recent treatment guidelines advocate using such parameters to guide management decisions. Although PAH is characterised by the presence of pulmonary vasculopathy, it is the response of the right ventricle to an increased afterload that is the greatest determinant of a patient's symptoms and survival; thus, measurements that capture right ventricular function provide the best potential to assess PAH severity. One challenge is to understand how the tests we use in everyday clinical practice relate to right heart function in PAH patients, and how current measures can be improved and developed to optimise assessment of disease status and progress. Future research in the field of PAH should focus on how best to assess right heart function, and which measures or combination of measures provide the most relevant information for the individual patient.

Patients with diabetes mellitus and cardiovascular disease have a high risk of mortality and/or recurrent cardiovascular events. Hypertension control is critical for secondary prevention of cardiovascular events. The objective was to determine rates and predictors of achieving hypertension control among Medicare patients with diabetes and uncontrolled hypertension after hospital discharge for an initial cardiac event. A retrospective analysis of linked electronic health record and Medicare data was performed. The primary outcome was hypertension control within 1 year after hospital discharge for an initial cardiac event. Cox proportional hazard models assessed sociodemographics, medications, utilization, and comorbidities as predictors of control. Medicare patients with diabetes were more likely to achieve hypertension control when prescribed beta-blockers at discharge or with a history of more specialty visits. Adults ≥ 80 were more likely to achieve control with diuretics. These findings demonstrate the importance of implementing guideline-directed multidisciplinary care in this complex and high-risk population. ©2018 Wiley Periodicals, Inc.

1997-01-01

The usefulness of 123 I-BMIPP myocardial SPECT in discriminating hypertrophic cardiomyopathy (46 patients), hypertrophic cardiomyopathy with hypertension (23 patients), and hypertensive hypertrophic heart (20 patients) was studied. SPECT image was divided into 17 domains, and dimension of decreased accumulation was decided visually at each domain as four classes called defect score (DS). Summation of DS (TDS) of each group was used to compare frequency and dimension of decreased accumulation, and characteristic of each site. Frequency of decreased accumulation and TDS in hypertrophic cardiomyopathy were similar in dimension with those in hypertrophic cardiomyopathy with hypertension, and those data in hypertensive hypertrophic heart were lower than those in above-mentioned 2 groups. In the cases of hypertrophic cardiomyopathy and hypertrophic cardiomyopathy with hypertension, decreased accumulation site was similar and was anterior wall-septum junction, septum-posterior wall junction and apex of heart. In the case of hypertensive hypertrophic heart, decreased accumulation site was only the posterior wall. Frequency, dimension and site of decreased accumulation in hypertrophic cardiomyopathy were different from those in hypertensive hypertrophic heart, and BMIPP was thought to be useful in discriminating these diseases.

Despite improvements in hypertension awareness and treatment, 30%-60% of hypertensive patients do not achieve BP targets and subsequently remain at risk for target organ damage. This therapeutic gap is particularly important to nephrologists, who frequently encounter treatment-resistant hypertension in patients with CKD. Data are limited on how best to treat patients with CKD and resistant hypertension, because patients with CKD have historically been excluded from hypertension treatment trials. First, we propose a consistent definition of resistant hypertension as BP levels confirmed by both in-office and out-of-office measurements that exceed appropriate targets while the patient is receiving treatment with at least three antihypertensive medications, including a diuretic, at dosages optimized to provide maximum benefit in the absence of intolerable side effects. Second, we recommend that each patient undergo a standardized, stepwise evaluation to assess adherence to dietary and lifestyle modifications and antihypertensive medications to identify and reduce barriers and discontinue use of substances that may exacerbate hypertension. Patients in whom there is high clinical suspicion should be evaluated for potential secondary causes of hypertension. Evidence-based management of resistant hypertension is discussed with special considerations of the differences in approach to patients with and without CKD, including the specific roles of diuretics and mineralocorticoid receptor antagonists and the current place of emerging therapies, such as renal denervation and baroreceptor stimulation. We endorse use of such a systematic approach to improve recognition and care for this vulnerable patient group that is at high risk for future kidney and cardiovascular events.

Osteoprotegerin (OPG) is a glycoprotein that plays an important regulatory role in the skeletal, vascular, and immune system. It has been shown that OPG predicts chronic kidney disease (CKD) in diabetic patients. We hypothesized that OPG could be a risk marker of CKD development also in non-diabetic hypertensive patients. A case-control study was carried out to measure circulating OPG levels in 42 hypertensive patients with CKD and in 141 hypertensive patients without CKD. A potential relationship between OPG and the presence of CKD was investigated and a receiver-operating characteristic (ROC) curve was designed thereafter to identify a cut-off value of OPG that best explained the presence of CKD. Secondly, to evaluate whether OPG increase could affect the kidney, 18 C57BL/6J mice were randomized to be treated with saline or recombinant OPG every 3 weeks for 12 weeks. Circulating OPG levels were significantly higher in hypertensive patients with CKD, and there was a significant inverse association between OPG and renal function, that was independent from other variables. ROC analysis showed that OPG levels had a high statistically predictive value on CKD in hypertensive patients, which was greater than that of hypertension. The OPG best cut-off value associated with CKD was 1109.19 ng/L. In the experimental study, OPG delivery significantly increased the gene expression of pro-inflammatory and pro-fibrotic mediators, as well as the glomerular nitrosylation of proteins. This study shows that OPG is associated with CKD in hypertensive patients, where it might have a higher predictive value than that of hypertension for CKD development. Secondly, we found that OPG delivery significantly increased the expression of molecular pathways involved in kidney damage. Further longitudinal studies are needed not only to evaluate whether OPG predicts CKD development but also to clarify whether OPG should be considered a risk factor for CKD.

The goal of the study was to determine the blood pressure (BP) response to renal artery stenting (RAS) for patients with hypertension urgency, hypertension emergency, and angina with congestive heart failure (angina/congestive heart failure [CHF]). Patients who underwent RAS for hypertension emergencies (n = 13), hypertension urgencies (n = 25), and angina/CHF (n = 14) were included in the analysis. By convention, hypertension urgency was defined by a sustained systolic BP ≥ 180 mm Hg or diastolic BP ≥ 120 mm Hg, while the definition of hypertension emergency required the same BP parameters plus hypertension-related symptoms prompting hospitalization. Patient-specific response to RAS was defined according to modified American Heart Association reporting guidelines. The study cohort of 52 patients had a median age of 66 years (interquartile range 58-72). The BP response to RAS varied significantly according to the indication for RAS. Hypertension emergency provided the highest BP response rate (85%), while the response rate was significantly lower for hypertension urgency (52%) and angina/CHF (7%; P = .03). Only 1 of 14 patients with angina/CHF was a BP responder. Multivariate analysis showed that hypertension urgency or emergency were not independent predictors of BP response to RAS. Instead, the only independent predictor of a favorable BP response was the number of preoperative antihypertensive medications (odds ratio 7.5; 95% confidence interval 2.5-22.9; P = .0004), which is another indicator of the severity of hypertension. Angina/CHF was an independent predictor of failure to respond to RAS (odds ratio 118.6; 95% confidence interval 2.8-999.9; P = .013). Hypertension urgency and emergency are clinical manifestations of severe hypertension, but the number of preoperative antihypertensive medications proved to be a better predictor of a favorable BP response to RAS. In contrast, angina/CHF was a predictor of failure to respond to stenting, providing further

Full Text Available INTRODUCTION: Chronic thromboembolic pulmonary hypertension is a disease affecting approximately 4,000 people per year in the United States. The incidence rate in Brazil, however, is unknown. The estimated survival for patients with chronic thromboembolic pulmonary hypertension without treatment is approximately three years. Pulmonary thromboendarterectomy for select patients is a potentially curative procedure when correctly applied. In Brazil, the clinical and hemodynamic profiles of chronic thromboembolic pulmonary hypertension patients have yet to be described. OBJECTIVES: To evaluate the clinical and hemodynamic characteristics of chronic thromboembolic pulmonary hypertension patients scheduled for pulmonary thromboendarterectomy in a referral center for chronic thromboembolic pulmonary hypertension treatment in Brazil. METHODS: From December 2006 to November 2009, patients were evaluated and scheduled for pulmonary thromboendarterectomy. The subjects were classified according to gender, age and functional class and were tested for thrombofilia and brain natriuretic peptide levels. RESULTS: Thirty-five consecutive chronic thromboembolic pulmonary hypertension patients were evaluated. Two patients tested positive for schistosomiasis, and 31 were enrolled in the study (19 female, 12 male. The majority of patients were categorized in functional classes III and IV. Hemodynamic data showed a mean pulmonary vascular resistance (PVR of 970.8 ± 494.36 dynas·s·cm-5 and a low cardiac output of 3.378 ± 1.13 L/min. Linear regression revealed a direct relation between cardiac output and pulmonary vascular resistance. Paradoxical septal movement was strongly correlated with pulmonary vascular resistance and cardiac output (p=0.001. Brain natriuretic peptide serum levels were elevated in 19 of 27 patients. CONCLUSIONS: In a referral center for pulmonary hypertension in Brazil, chronic thromboembolic pulmonary hypertension patients evaluated for

Chronic diseases can act as an accelerating factor in the auditory system degeneration. Studies on the association between presbycusis and diabetes mellitus and systemic arterial hypertension have shown controversial conclusions. To compare the initial audiometry (A1) with a subsequent audiometry (A2) performed after a 3 to 4-year interval in a population of elderly patients with diabetes mellitus and/or systemic arterial hypertension, to verify whether hearing loss in these groups is more accelerated when compared to controls without these clinical conditions. 100 elderly individuals participated in this study. For the auditory threshold assessment, a previous complete audiological evaluation (A1) and a new audiological evaluation (A2) performed 3-4 years after the first one was utilized. The participants were divided into four groups: 20 individuals in the diabetes mellitus group, 20 individuals in the systemic arterial hypertension group, 20 individuals in the diabetes mellitus/systemic arterial hypertension group and 40 individuals in the control group, matching them with each study group, according to age and gender. ANOVA and Kruskal-Wallis statistical tests were used, with a significance level set at 0.05. When comparing the mean annual increase in the auditory thresholds of the A1 with the A2 assessment, considering each study group and its respective control, it can be observed that there was no statistically significant difference for any of the frequencies for the diabetes mellitus group; for the systemic arterial hypertension group, significant differences were observed after 4kHz. For the diabetes mellitus and systemic arterial hypertension group, significant differences were observed at the frequencies of 500, 2kHz, 3kHz and 8kHz. It was observed that the systemic arterial hypertension group showed the greatest decrease in auditory thresholds in the studied segment when compared to the other groups, suggesting that among the three studied conditions

Full Text Available Abstract Background No comparisons have been made of scales estimating cardiovascular mortality and overall cardiovascular morbidity and mortality. The study objectives were to assess the agreement between the Framingham-D'Agostino cardiovascular risk (CVR scale and the chart currently recommended in Europe (SCORE with regard to identification of patients with high CVR, and to describe the discrepancies between them and the attendant implications for the treatment of hypertension and hyperlipidaemia. Methods A total of 474 hypertensive patients aged 40–65 years monitored in primary care were enrolled into the study. CVR was assessed using the Framingham-D'Agostino scale, which estimates the overall cardiovascular morbidity and mortality risk, and the SCORE chart, which estimates the cardiovascular mortality risk. Cardiovascular risk was considered to be high for values ≥ 20% and ≥ 5% according to the Framingham-D'Agostino and SCORE charts respectively. Kappa statistics was estimated for agreement in classification of patients with high CVR. The therapeutic recommendations in the 2007 European Guidelines on Cardiovascular Disease Prevention were followed. Results Mean patient age was 54.1 (SD 7.3, and 58.4% were males. A high CVR was found in 17.5% using the SCORE chart (25.3% males, 6.6% females and in 32.7% using the D'Agostino method (56.9% males, 12,7% females. Kappa coefficient was 0.52, and increased to 0.68 when the high CVR threshold was established at 29% according to D'Agostino. Hypertensive patients with high SCORE and non-high D'Agostino (1.7% were characterized by an older age, diabetes, and a lower atherogenic index, while the opposite situation (16.9% was associated to males, hyperlipidaemia, and a higher atherogenic index. Variables with a greater weight in discrepancies were sex and smoking. A 32.0% according to SCORE and 33.5% according to D'Agostino would be candidates to receive antihypertensive treatment, and 15.8% and

The relationship between hypertension and fluid overload in pre-dialysis CKD patients need to be elucidated. Current study aimed to find relationship between fluid overload and hypertension along with prescribed diuretic therapy using bioimpedance spectroscopy (BIS). A prospective observational study was conducted by inviting pre-dialysis CKD patients. Fluid overload was assessed by BIS. A total of 312 CKD patients with mean eGFR 24.5 ± 11.2 ml/min/1.73 m 2 were enrolled. Based on OH value ≥7 %, 135 (43.3 %) patients were hypervolemic while euvolemia was observed in 177 (56.7 %) patients. Patients were categorized in different regions of hydration reference plot (HRP) generated by BIS i.e., 5.1 % in region-N (normal BP and fluid status), 20.5 % in region I (hypertensive with severe fluid overload), 29.5 % in region I-II (hypertensive with mild fluid overload), 22 % in region II (hypertensive with normohydration), 10.2 % in region III (underhydration with normal/low BP) and 12.5 % in region IV (normal BP with severe fluid overload). A total of 144 (46 %) patients received diuretics on basis of physician assessment of BP and edema. Maximum diuretics 100 (69.4 %) were prescribed in patients belonging to regions I and I-II of HRP. Interestingly, a similar number of diuretic prescriptions were observed in region II (13 %) and region IV (12 %). Surprisingly, 7 (4.9 %) of patients in region III who were neither hypervolemic nor hypertensive were also prescribed with diuretics. BIS can aid clinicians to categorize CKD patients on basis of their fluid status and provide individualized pharmacotherapy to manage hypertensive CKD patients.

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.

Full Text Available Aim. To asses effects of amlodipin and metoprolol on autonomic system in emotional and cold tests in hypertensive patients with different psychological profile (PP Material and methods. 61 patients with arterial hypertension of II grade were observed. Therapy with amlodipin or metoprolol was prescribed and allowed to reach target blood pressure (BP level in all the patients. Patients were divided into 2 groups: 1-st one – patients with normal PP, 2-nd group – patients with subclinical depression. Patients were examined before and 30 days after therapy. Examination included ambulatory BP monitoring, assessment of autonomic status by variational intervalometry and spectral analysis of heart rate variability (HRV in cold and emotional tests. Depression and anxiety levels were determined with Bek’s and HADS scales.  Results. Treatment with amlodipin  and metoprolol can result in improvement, worsening or unchanging of PP.  In hypertensive patients with subclinical depression improving their PP resulted in autonomic reaction change: sympathetic activity increases and reaction on stress becomes more adequate. If subclinical depression occurred in hypertensive patients because of amlodipin and metoprolol therapy, sympathetic system stress-reaction decreased and parasympathetic influence increased. Conclusion. The study results show necessity of psychometric examination of hypertensive patients in order to reveal subclinical depression and anxiety.

Significantly elevated risks of stroke (10,211 events; adjusted HR 1.17; 95%CI 1.08–1.27; p<0.001), especially ischemic stroke (6,235 events; adjusted HR 1.34; 95%CI 1.20–1.48; p<0.001), but not all-cause mortality (4,594 events; adjusted HR 1.06; 95%CI 0.95–1.19; p = 0.312) or acute coronary syndrome (2,145 events; adjusted HR 1.17; 95%CI 0.99–1.39; p = 0.070) were noted in patients with RH compared to those with non-RH. Subgroup analysis showed that RH increased the risks of stroke in female and elderly patients. However, no significant influence was noted in young or male patients. Conclusions Patients with RH were associated with higher risks of MACE and stroke, especially ischemic stroke. The risks were greater in female and

Previous studies have shown that depression and anxiety were independent risk factors for hypertension. Non-dipper hypertension is associated with higher cardiovascular mortality. The aim of this study was to evaluate the anxiety and depression scores in patients with dipper and non-dipper hypertension. The study sample consisted of 153 hypertensive patients. All patients underwent 24-h blood pressure monitoring. Patients were classified into two groups according to their dipper or non-dipper hypertension status. We evaluated results of the Hospital Anxiety and Depression Scale between groups. Seventy-eight patients (38 male, mean age: 51.6 ± 12.5 years) had dipper hypertension while 75 patients (27 male, mean age: 55.4 ± 14.1 years) had non-dipper hypertension (p = 0.141, 0.072, respectively). Clinical characteristics were similar for both groups. Patients with non-dipper hypertension had significantly higher depression and anxiety scores compared to patients with dipper hypertension. Dipper and non-dipper status significantly correlated with anxiety (p: 0.025, r: 0.181) and depression score (p: 0.001, r: 0.255). In univariate analysis, smoking, alcohol usage, presence of diabetes, hyperlipidemia, anxiety score >8 and depression score >7 were predictors of dipper versus non-dipper status. In multivariate logistic regression analyses only depression score >7 was independent predictor of dipper versus non-dipper status (odds ratio: 2.74, confidence intervals: 1.41-5.37). A depression score of 7 or higher predicted non-dipper status with a sensitivity of 62.7% and specificity of 62.8%. Non-dipper patients have significantly higher anxiety and depression scores compared to dipper patients. Evaluation of anxiety and depression in patients with hypertension might help to detect non-dipper group and hence guide for better management.

Full Text Available Objective: Comparison of the hemodynamic effect of ethomidate induction in normotensive and hypertensive patients. Methods: Forty ASA 1-2 patients were included. After informed consent were obtained, patients were divided into two group; Group H: Hypertensive patients, Group N: Normotensive patients. Fentanile and midazolam were administrated for premedication. Anesthesia induction was performed by etomidate 0.3 mg/kg and rocuronium 0.6 mg/kg. Arterial pressures and heart rates were measured at certain intervals: control, pre-intubation and 1, 3 and 5 min post-intubation. Myoclonic movements and hemodynamic parameters were noted by an anesthetist who was masked to the groups. Results: Hemodynamic parameters were higher in hypertensive patients but were in clinically tolerable limits. Conclusion: No hemodynamic instability was observed in anesthesia induction with ethomidate in neither hypertensive nor normotensive patients. J Clin Exp Invest 2014; 5 (2: 164-168

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.

Increasingly, apparent treatment-resistant hypertension has been recognized. However, much of the prevalence, predictors, and outcomes are largely unknown, especially in patients with coronary artery disease. We evaluated 10,001 patients with coronary artery disease who were enrolled in the Treating to New Targets trial. Apparent treatment-resistant hypertension was defined as blood pressure ≥ 140 mm Hg despite 3 antihypertensive agents or hypertension. In a multivariable model adjusting for baseline differences, the treatment-resistant hypertension group had a 64% increase in primary outcome (hazard ratio [HR], 1.64; 95% confidence interval [CI], 1.39-1.94; P hypertension group. In addition, patients with apparent treatment-resistant hypertension had a 71% increase in major coronary event (P hypertension group. Results were largely similar whether the definition of apparent treatment-resistant hypertension was based on a blood pressure ≥ 140 mm Hg despite 3 agents or a blood pressure hypertension is associated with a marked increase in the risk of cardiovascular morbidity and mortality, including an increase in all-cause death.

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.

Full Text Available OBJECTIVE: To evaluate the characteristics of the patients receiving medical care in the Ambulatory of Hypertension of the Emergency Department, Division of Cardiology, and in the Emergency Unit of the Clinical Hospital of the Ribeirão Preto Medical School. METHODS: Using a protocol, we compared the care of the same hypertensive patients in on different occasions in the 2 different places. The characteristics of 62 patients, 29 men with a mean age of 57 years, were analyzed between January 1996 and December 1997. RESULTS: The care of these patients resulted in different medical treatment regardless of their clinical features and blood pressure levels. Thus, in the Emergency Unit, 97% presented with symptoms, and 64.5% received medication to rapidly reduce blood pressure. In 50% of the cases, nifedipine SL was the elected medication. Patients who applied to the Ambulatory of Hypertension presenting with similar features, or, in some cases, presenting with similar clinically higher levels of blood pressure, were not prescribed medication for a rapid reduction of blood pressure at any of the appointments. CONCLUSION: The therapeutic approach to patients with high blood pressure levels, symptomatic or asymptomatic, was dependent on the place of treatment. In the Emergency Unit, the conduct was, in the majority of cases, to decrease blood pressure immediately, whereas in the Ambulatory of Hypertension, the same levels of blood pressure, in the same individuals, resulted in therapeutic adjustment with nonpharmacological management. These results show the need to reconsider the concept of hypertensive crises and their therapeutical implications.

2008-01-01

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)

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.

Factors associated with high brachial–ankle pulse wave velocity in non-hypertensive and appropriately treated hypertensive patients with atherosclerotic risk factors

Full Text Available Dai Ato,1 Toshitami Sawayama2 1Gakujutsu Shien (Academic Support Co., Ltd. Tokyo, 2Sawayama Clinic, Okayama, Japan Abstract: While pulse wave velocity (PWV correlates with blood pressure (BP, its extent differs between patients, and some cases of high PWV in normotensives are present. Moreover, PWV frequently remains high in hypertensive patients despite adequate BP control. The factors associated with such phenomena are yet to be elucidated. Here, we investigated the factors associated with brachial–ankle PWV (baPWV in 107 patients whose systolic BP was under 140 mmHg at their latest baPWV measurement. There were 64 controlled hypertensives and 43 normotensives. Multivariate regression analysis identified age, hypertension, body mass index (BMI, systolic BP, and heart rate (HR as independent factors for baPWV. Next, we divided the subjects into groups according to their age (in 5-year increments and calculated the mean and standard deviation (SD of the baPWV for each group. For each age group, we defined patients with a baPWV above the mean + SD baPWV for the group as the high-baPWV cohort. Multivariate logistic regression analysis revealed that BMI, hypertension, and smoking were independent determinants of a high-baPWV subject. This represents the first study to report the existence of the hypertensive state itself as one of the independent predictors of high baPWV in normotensive and well-treated hypertensive patients. This finding implies that the hypertensive state itself possibly worsens arterial stiffness independently from aging in spite of adequate BP maintenance. To prevent the early progression of arterial stiffness, the application of an appropriate intervention during the early stages of hypertension is important and the continuation of an appropriate BP treatment is suggested.

Full Text Available Among Kazakh-Chinese population in Xinjiang province of China, prevalence of obesity and hypertension were 40.1% and 50.3% respectively, the highest across all ethnic groups residing in this pastureland. Despite this, there remained a dearth of information regarding the association between the anthropometric measures [body mass index (BMI, waist circumference (WC, waist-hip ratio (WHR, Waist-to-height ratio (WHtR etc.] and indicators for hypertension control [achieved levels of systolic and diastolic blood pressures (SBP and DBP, pulse pressure index (PPI, ankle-brachial index (ABI etc.] among them.A cross-sectional study was conducted in Xinjiang to determine the distribution and inter-relationships of the anthropometric measures and indicators for achieved BP control as well as their predictors among hypertension patients of Kazakh-Chinese ethnicity. Out of 550 randomly selected patients, 516 completed the interview, anthropometry and BP assessments.In the sample population, average SBP, DBP and PP were 156.26±24.40mmHg, 87.55±14.73mmHg and 68.71±19.39mmHg respectively. Bivariate analysis identified age, gender, education, duration of hypertension, WC and BMI being factors influencing the achieved levels of BP. Adjusted multiple linear regression models elicited positive associations of age (βa = 0.152, p = 0.001 and duration of hypertension (βa = 0.132, p = 0.003 with achieved level of SBP as well as BMI (βa = 0.135, p = 0.002 with DBP. Age (βa = 0.207, p<0.001 and WHtR (βa = 0.304, p = 0.005 were positively and WC (βa = -0.406, p<0.001 was negatively associated with PPI. Increasing age (βa = -0.125, p = 0.005, female gender (βa = -0.122, p = 0.005 and 5years' duration of hypertension (βa = -0.091, p<0.039 were negatively associated with ABI. After adjustment for socio-demographic variables, hypertensive patients with (reference = without abdominal obesity had 93% (p = 0.013 higher odds of missing the target BP control

Hypertensive crisis during pregnancy and postpartum period.

Too, Gloria T; Hill, James B

2013-08-01

Hypertension affects 10% of pregnancies, many with underlying chronic hypertension, and approximately 1-2% will undergo a hypertensive crisis at some point during their lives. Hypertensive crisis includes hypertensive urgency and emergency; the American College of Obstetricians and Gynecologists describes a hypertensive emergency in pregnancy as persistent (lasting 15 min or more), acute-onset, severe hypertension, defined as systolic BP greater than 160 mmHg or diastolic BP >110 mmHg in the setting of pre-eclampsia or eclampsia. Pregnancy may be complicated by hypertensive crisis, with lower blood pressure threshold for end-organ damage than non-pregnant patients. Maternal assessment should include a thorough history. Fetal assessment should include heart rate tracing, ultrasound for growth and amniotic assessment, and Doppler evaluation if growth restriction is suspected. Initial management of hypertensive emergency (systolic BP >160 mmHg or diastolic BP >110 mmHg in the setting of pre-eclampsia or eclampsia) generally includes the rapid reduction of blood pressure through the use of intravenous antihypertensive medications, with goal systolic blood pressure between 140 mmHg and 150 mmHg and diastolic pressure between 90 mmHg and 100 mmHg. First-line intravenous drugs include labetalol and hydralazine, but other agents may be used, including esmolol, nicardipine, nifedipine, and, as a last resort, sodium nitroprusside. Among patients with hypertensive urgency, slower blood pressure reduction can be provided with oral agents. The objective of this article is to review the current understanding, diagnosis, and management of hypertensive crisis during pregnancy and the postpartum period. Copyright © 2013 Elsevier Inc.

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.

Full Text Available Abstract Background The burden of non-communicable chronic diseases, such as hypertension and diabetes, increases in sub-Saharan Africa. However, the majority of the rural population does still not have access to adequate care. The objective of this study is to examine the effectiveness of integrating care for hypertension and type 2 diabetes by task shifting to non-physician clinician (NPC facilities in eight rural health districts in Cameroon. Methods Of the 75 NPC facilities in the area, 69 (87% received basic equipment and training in hypertension and diabetes care. Effectiveness was assessed after two years on status of equipment, knowledge among trained NPCs, number of newly detected patients, retention of patients under care, treatment cost to patients and changes in blood pressure (BP and fasting plasma glucose (FPG among treated patients. Results Two years into the programme, of 54 facilities (78% available for re-assessment, all possessed a functional sphygmomanometer and stethoscope (65% at baseline; 96% stocked antihypertensive drugs (27% at baseline; 70% possessed a functional glucose meter and 72% stocked oral anti-diabetics (15% and 12% at baseline. NPCs' performance on multiple-choice questions of the knowledge-test was significantly improved. During a period of two years, trained NPCs initiated treatment for 796 patients with hypertension and/or diabetes. The retention of treated patients at one year was 18.1%. Hypertensive and diabetic patients paid a median monthly amount of 1.4 and 0.7 Euro respectively for their medication. Among hypertensive patients with ≥ 2 documented visits (n = 493, systolic BP decreased by 22.8 mmHg (95% CI: -20.6 to -24.9; p Conclusions The integration of hypertension and diabetes into primary health care of NPC facilities in rural Cameroon was feasible in terms of equipment and training, accessible in terms of treatment cost and showed promising BP- and FPG-trends. However, low case-detection rates

Two-thirds of patients with type 2 diabetes mellitus (T2DM) have arterial hypertension. Hypertension increases the incidence of both micro- and macrovascular complications in these patients, while the co-existence of these two major risk factors leads to a four-fold increased risk for cardiovascular disease (CVD) compared with normotensive non-diabetic controls. The aim of this article is to comprehensively review the literature and present updated information on targets for blood pressure (BP) and on the management of hypertension in patients with T2DM. A BP target of <140/90 mmHg applies to most patients, but individualization is always important. All classes of antihypertensive drugs can be used in the management of hypertension in patients with T2DM, as long as they are effective and safe and after taking co-morbidities into account. Angiotensin-converting-enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) are the ideal choice for initial or early treatment of hypertension in patients with T2DM and albuminuria. Combination of two or more drugs seems to be inevitable as most of these patients demonstrate resistant hypertension. The combination of ACE inhibitors with ARBs should be avoided. Thiazide and thiazide-like diuretics might be beneficial, alone or in a fixed-dose combination with ACE inhibitors or ARBs. Calcium channel blockers (CCBs) constitute an ideal option as a second- or third-line agent. Beta-blockers are not considered as first-line antihypertensive agents, except for those patients with heart failure or previous myocardial infarction. The addition of mineralocorticoid receptor antagonists to a triple-drug therapy seems the next ideal step. Gender-specific characteristics regarding BP, T2DM and CVD should be taken into consideration, even if different recommendations do not exist yet. Copyright © 2018. Published by Elsevier B.V.

The association between hypertensive phenotypes of controlled hypertension (CH), white-coat effect (WCE), masked uncontrolled hypertension (MUH) and sustained hypertension (SH) with target organ damage have not been clearly established in diabetic hypertensive treated patients. The present study aims to evaluate the prevalence of the four phenotypes considering the current cut-off points for office and 24 h-ambulatory blood pressure monitoring (ABPM) and the association with left ventricle hypertrophy (LVH), diastolic function and nephropathy. Cross-sectional study with 304 patients on anti-hypertensive treatment aged 57.6 ± 6.1 years, who were submitted to ABPM and echocardiography. They were classified into CH (normal office BP and ABPM), WCE (high office BP and normal ABPM), MUH (normal office BP and high ABPM), and SH (high office BP and ABPM). Median HbA1c and diabetes duration were 7.9% (6.8-9.2), and 10 years (5-16), respectively. Prevalences of CH, WCE, MUH and SH were 27.3%, 17.1%, 18.8%, and 36.8%. MUH prevalence was higher than previously described. There was a significant increasing trend across the four groups in variables related to LVH (P ABPM beyond the traditional cardiovascular risk stratification tools has limitations, but is still useful in high-risk patients. Longitudinal studies could better evaluate the role of the use of ABPM in this scenario. Cut-off points for normality of office and ABPM influence the prevalences of WCH and MUH. © 2014 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

Renal Artery Stenosis in Patients with Resistant Hypertension: Stent It or Not?

After three large neutral trials in which renal artery revascularization failed to reduce cardiovascular and renal morbidity and mortality, renal artery stenting became a therapeutic taboo. However, this is probably unjustified as these trials have important limitations and excluded patients most likely to benefit from revascularization. In particular, patients with severe hypertension were often excluded and resistant hypertension was either poorly described or not conform to the current definition. Effective pharmacological combination treatment can control blood pressure in most patients with renovascular hypertension. However, it may also induce further renal hypoperfusion and thus accelerate progressive loss of renal tissue. Furthermore, case reports of patients with resistant hypertension showing substantial blood pressure improvement after successful revascularization are published over again. To identify those patients who would definitely respond to renal artery stenting, properly designed randomized clinical trials are definitely needed.

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.

Successful control of blood pressure relies on identification of secondary causes and contributing factors of hypertension. As antihypertensive medication can interfere with diagnostic investigations, temporary discontinuation of medication is advised. However, there are concerns about the safety of temporary discontinuation of antihypertensive medication in patients with difficult-to-control hypertension. We assessed the occurrence of adverse cardiovascular and cerebrovascular events potentially attributable to temporary discontinuation of antihypertensive medication between February 2010 and March 2016 (n=604) in our Analysis of Complicated Hypertension screening program. A reference group (n=604) was extracted from the SMART study (Second Manifestations of Arterial Disease) cohort (comprising a similar cohort at our hospital in whom medication was not stopped) and individually matched for blood pressure, age, sex, and history of cardiovascular disease. Discontinuation of medication was well tolerated; 62% reported no complaints, 24% had mild discomfort that could be left untreated, and 14% experienced complaints that required prescription of antihypertensive escape medication. Three major adverse events were observed in the Analysis of Complicated Hypertension group between discontinuation of medication and 30 days after restart of medication (event rate=31.2 events per 1000 patient-year). In the reference cohort, 5 cardiovascular events were observed during a similar follow-up period (event rate=51.2 events per 1000 patient-year). In conclusion, discontinuation of antihypertensive medication for the diagnostic evaluation of hypertension does not increase the acute risk of cardiovascular events when performed in a well-controlled setting in specialized hospitals with appropriate protocols for monitoring safety. © 2017 American Heart Association, Inc.

Epistaxis and hypertension are frequent conditions in the adult population. Masked hypertension is defined as a clinical condition in which a patient's office blood pressure level is epistaxis. The prevalence of this condition in patients with epistaxis is not well defined. This study aimed to evaluate the prevalence of masked hypertension using the results of office blood pressure measurement compared with the results of ambulatory blood pressure monitoring. Sixty patients with epistaxis and 60 control subjects were enrolled in the study. All patients with epistaxis and controls without history of hypertension underwent physical examination, including office blood pressure measurement, ambulatory or home blood pressure, and measurement of anthropometric parameters. Mean age was similar between the epistaxis group and the controls - 21-68 years (mean 42.9) for the epistaxis group and 18-71 years (mean 42.2) for the control group. A total of 20 patients (33.3%) in the epistaxis group and 7 patients (11.7%) in the control group (p=0.004) had masked hypertension. Night-time systolic blood pressure was significantly higher in patients with epistaxis than in the control group (pepistaxis (p=0.517). This study demonstrates increased masked hypertension prevalence in patients with epistaxis. We suggest that all patients with epistaxis should undergo ambulatory or home blood pressure to detect masked hypertension, which could be a possible cause of epistaxis.

Hypertension is both a cause and consequence of chronic kidney disease (CKD). According to the Chinese national survey in 2007-2010, the prevalence of CKD was much higher in hypertensive patients (18.9%, n=16,691) than in the overall population sample (10.8%, n=47,204). CKD in hypertension confers risks to the kidneys as well as other organs. Probably because of high dietary salt intake, Asian hypertensive patients with CKD show high prevalence of non-dipping and reversed dipping blood pressure pattern, and may have even higher risks of cardiovascular disease. Therefore, out-of-office blood pressure evaluation and comprehensive cardiovascular evaluations are required. Most of current hypertension guidelines recommend intensive antihypertensive treatment in hypertensive patients with CKD. This is probably of particular relevance for cardiovascular prevention in Asia, because stroke, as a major complication of hypertension in Asia, is more closely related to blood pressure than coronary events. Intensive blood pressure control to 130/80 mmHg is often required to prevent CKD progression and cardiovascular complications. The inhibitors of the renin-angiotensin system (RAS) are recommended as the first line antihypertensive medications in patients with a glomerular filtration rate higher than 30 ml/min/1.73 m², which may more efficaciously prevent end-stage renal disease and cardiovascular events. Nonetheless, combination therapy of RAS inhibitors with other classes of antihypertensive drugs, such as calcium-channel blockers, diuretics, etc, is required to control blood pressure to the target.

Double inversion recovery (DIR) ''black blood'' MRI suppresses the signal from flowing blood, slow flowing blood causes incomplete suppression resulting in pulmonary blood flow artefact (PFA). This study examines the diagnostic utility and prognostic value of a PFA scoring system in a mixed cohort of patients with pulmonary hypertension (PH). DIR-MRI images were reviewed for 233 patients referred with suspected PH who underwent right heart catheterisation (RHC) within 48 h of MR. The degree of PFA was visually scored in all patients from 0 to 5 (0 = absent, 1 = segmental, 2 = lobar, 3 = distal main, 4 = proximal main and 5 = trunk). Pulmonary artery (PA), aorta (Ao), and PA main branch diameters were measured from which PA/Ao ratios and mean PA branch diameters (MPAB) were calculated. PFA >1 demonstrated high sensitivity (86%) and specificity (85%) for the diagnosis PH in our mixed patient cohort. A good correlation was found with PFA and haemodynamic parameters, PVR (r = 0.70), mPAP (r = 0.65) and CI (r = -0.53). PFA predicted mortality (P = 0.005) during the mean follow-up for 19 months. PFA scoring demonstrated good inter-observer agreement (k = 0.83). PFA scoring is of diagnostic and prognostic value in the assessment of patients with suspected PH. and is a predictor of mortality.

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.

Data from the Registry to Evaluate Early and Long-Term Pulmonary Arterial Hypertension Disease Management (REVEAL) were used previously to develop a risk score calculator to predict 1-year survival. We evaluated prognostic implications of changes in the risk score and individual risk-score parameters over 12 months. Patients were grouped by decreased, unchanged, or increased risk score from enrollment to 12 months. Kaplan-Meier estimates of subsequent 1-year survival were made based on change in the risk score during the initial 12 months of follow-up. Cox regression was used for multivariable analysis. Of 2,529 patients in the analysis cohort, the risk score was decreased in 800, unchanged in 959, and increased in 770 at 12 months post-enrollment. Six parameters (functional class, systolic blood pressure, heart rate, 6-minute walk distance, brain natriuretic peptide levels, and pericardial effusion) each changed sufficiently over time to improve or worsen risk scores in ≥5% of patients. One-year survival estimates in the subsequent year were 93.7%, 90.3%, and 84.6% in patients with a decreased, unchanged, and increased risk score at 12 months, respectively. Change in risk score significantly predicted future survival, adjusting for risk at enrollment. Considering follow-up risk concurrently with risk at enrollment, follow-up risk was a much stronger predictor, although risk at enrollment maintained a significant effect on future survival. Changes in REVEAL risk scores occur in most patients with pulmonary arterial hypertension over a 12-month period and are predictive of survival. Thus, serial risk score assessments can identify changes in disease trajectory that may warrant treatment modifications. Copyright © 2015 International Society for Heart and Lung Transplantation.

Full Text Available Introduction : Diet plays a significant role in the prevention and treatment of arterial hypertension. Appropriate diet makes it possible to maintain adequate body weight and improve biochemical blood parameters. The aim of the study was to assess nutritional status of arterial hypertension patients in terms of their diet. Material and methods: The study involved 55 patients diagnosed with arterial hypertension aged 45-70 years. Diet was evaluated using a 24-hour 7-day diet recall interview. In the course of the diet recall interview arterial pressure was measured three times at regular times, after a 15-minute rest period, and the recorded values were averaged. Nutritional status was assessed based on anthropometric measurements (height, body weight, waist circumference, hip circumference and the resulting nutrition status indexes, i.e. BMI (body mass index, WHR (waist-hip ratio as well as values of biochemical blood parameters. Conclusions : It was found that a considerable proportion of patients are overweight or obese, have an inappropriate lipid profile and elevated blood glucose levels. Daily food rations (DFR were inappropriately balanced. Daily food rations were deficient in energy, carbohydrates, dietary fibre, PUFA and folates. It was found that inadequate diet was correlated with nutritional status, lipid profile parameters and arterial blood pressure.

AIM: To describe direct pulmonary artery-to-pulmonary artery anastomoses seen at pulmonary angiography in patients with chronic thromboembolic pulmonary hypertension and discuss their possible significance. MATERIALS AND METHODS: Between 1 August 2000 and 31 July 2004 43 patients (male-to-female ratio 25:18) with a diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) underwent selective pulmonary angiography to assess the extent of disease and suitability for surgical pulmonary endarterectomy. The mean pulmonary artery pressure ranged from 27-84 mmHg (average of 51 mmHg). Selective bilateral digital subtraction pulmonary angiograms performed in all individuals were reviewed for the presence of intrapulmonary collaterals. RESULTS: In 15 of the 43 patients (male-to-female ratio =7:8) definite (n=12) or probable (n=3) pulmonary artery-to-pulmonary artery anastomoses were demonstrated. Of the remaining 28 patients in whom intrapulmonary collaterals were not seen it was felt that in 16 the angiograms were of insufficient diagnostic quality (grades 4-5) to exclude their presence. Twelve patients, eight of whom had angiograms of sufficient diagnostic quality (grades 1-3), demonstrated one or more areas of luxury perfusion but intrapulmonary collaterals were not seen. CONCLUSION: Direct pulmonary artery-to-pulmonary artery anastomoses were demonstrated in patients with chronic thromboembolic pulmonary hypertension, which to our knowledge have not been previously described. The importance of these collateral vessels is unclear but they may play a role in the maintenance of pulmonary parenchymal viability in patients with chronic pulmonary embolic disease. The rate of development of these collaterals and their prognostic significance in patients with chronic thromboembolic pulmonary hypertension are areas worthy of further study
