TL;DR: Improved lifestyle and control of risk factors via appropriate drug therapy are of importance in providing vascular protection related to EVA, including members of risk families including subjects with early onset cardiovascular disease.
Abstract: The influence of chronological ageing on the components of the cardiovascular system is of fundamental importance for understanding how hemodynamics change and the cardiovascular risk increases with age, the most important risk marker. An increase in peripheral vascular resistance associated with increased stiffness of central elastic arteries represents hallmarks of this ageing effect on the vasculature, referred to as early vascular ageing (EVA). In clinical practice, it translates into increased brachial and central systolic blood pressure and corresponding pulse pressure in subjects above 50 years of age, as well as increased carotid-femoral pulse wave velocity (c-f PWV)--a marker of arterial stiffness. A c-f PWV value ≥ 10 m/s is threshold for increased risk according. Improved lifestyle and control of risk factors via appropriate drug therapy are of importance in providing vascular protection related to EVA. One target group might be members of risk families including subjects with early onset cardiovascular disease.

TL;DR: Fasting improves PP and lipids profile and ameliorates oxidative stress in hypertensives.
Abstract: Background and aim. Effects of Ramadan fasting on health are important. Its effects on arterial pulse pressure (PP), lipid profile and oxidative stress were characterized in hypertensives. Methods. PP, indices of lipid profile and oxidative stress were measured pre-, during and post-fasting in equal (40 each), sex- and age-matched groups (age 55 ± 5 years) of hypertensives (HT) and controls (C). Results. Fasting reduced PP significantly by 17.2% and insignificantly by 9.3% in the HT and C groups, respectively. Total cholesterol (TC) was lowered insignificantly by 11.7% and 4.7% in the HT and C patients, respectively. Triglycerides (TG) and malondialdehyde (MDA) were significantly lowered by: TG: 24.5% and 22.8%; MDA: 45.6% and 54.3%; while glutathione (GSH) elevated by 56.8% and 52.6% in the HT and C groups, respectively. High-density lipoproteins (HDL) were raised significantly by 33.3% and insignificantly by 6.7%, whereas low-density lipoproteins (LDL) decreased significantly by 17.7% and insign...

TL;DR: This large and representative database shows that there is room for improvement of BP control in Sweden, and will provide a rich source for further research of hypertension and its complications.
Abstract: Objective. To describe the Swedish Primary Care Cardiovascular Database, SPCCD. Design. Longitudinal data from electronic medical records, linked to national registers. Setting. 48 primary healthcare centres in urban (south-western Stockholm) and rural (Skaraborg) regions in Sweden. Subjects. Patients diagnosed with hypertension 2001–2008. Main outcome measures. Blood pressure (BP) and impact of retrieval of data on BP levels, clinical characteristics, co-morbidity and pharmacological treatment. Results. The SPCCD contains 74 751 individuals, 56% women. Completeness of data ranged from > 99% for drug prescriptions to 34% for smoking habits. BP was recorded in 98% of patients during 2001–2008 and in 63% in 2008. Mean BP based on the last recorded value in 2008 was 142 ± 17/80 ± 13 mmHg. Digit preference in BP measurements differed between the two regions, p < 0.001. Antihypertensive drugs were prescribed in primary healthcare to 88% of the patients in 2008; however, when all prescribers were includ...

TL;DR: The study aimed to explore and describe relevant aspects of hypertension and hypertension treatment, for use in the development of an interactive mobile phone self-report system, and suggested which clinical measures, lifestyle measures, symptoms and side-effects of treatment would be meaningful to include in such a system.
Abstract: Low adherence remains a struggle in hypertension management, despite improvement efforts. Presuming that increased patient participation is a possible approach, we collaborated with patients and healthcare professionals to design a self-report system to support self-management. The study aimed to explore and describe relevant aspects of hypertension and hypertension treatment, for use in the development of an interactive mobile phone self-report system. It further aimed to suggest which clinical measures, lifestyle measures, symptoms and side-effects of treatment would be meaningful to include in such a system. Five focus group interviews were performed with 15 patients and 12 healthcare professionals, and data was analysed using thematic analysis. Patients suggested trust, a good relationship with caregivers, and well-being as important aspects of hypertension self-management. Furthermore, they regarded blood pressure, dizziness, stress, headache and tiredness as important outcomes to include. Patients sought to understand interconnections between symptoms and variations in blood pressure, whilst healthcare professionals doubted patients’ ability to do so. Healthcare professionals emphasized accessibility, clear and consistent counselling, complication prevention and educational efforts. The study presents aspects of importance for follow-up to understand the interplay between blood pressure and daily life experiences for patients with hypertension.

TL;DR: The crisis was positively related to hypertension in males but no statistically significant relationship was found for females, and the male hypertension was, however, suppressed by concurrent changes in smoking and body weight.
Abstract: Background. Business cycles affect people's lives. A growing literature examines their effect on health outcomes. The available studies on the relationship between ambient economic conditions and cardiovascular health show mixed results. They are furthermore limited in their outcome measures, focusing mostly on mortality. Methods. We examined the relationship between economic conditions and cardiovascular disease and hypertension, using the Icelandic economic collapse of 2008. Logit regression analyses are used to examine the relationship between economic conditions and the probability of reporting a cardiovascular disease or hypertension. We furthermore investigated potential mediators of this relationship. The data used come from a health and lifestyle survey carried out by the Public Health Institute of Iceland in 2007 and 2009. Results. The crisis was positively related to hypertension in males but no statistically significant relationship was found for females. The mediation analyses indicate...

TL;DR: The mobile phone self-report system appears efficiently to capture information relevant in patients’ self-management of hypertension, and the effectiveness of this tool in improving self- management of hypertension in clinical practice is evaluated.
Abstract: Self-management support tools using technology may improve adherence to hypertension treatment. There is a need for user-friendly tools facilitating patients’ understanding of the interconnections between blood pressure, wellbeing and lifestyle. This study aimed to examine comprehension, comprehensiveness and relevance of items, and further to evaluate the usability and reliability of an interactive hypertension-specific mobile phone self-report system. Areas important in supporting self-management and candidate items were derived from five focus group interviews with patients and healthcare professionals (n = 27), supplemented by a literature review. Items and response formats were drafted to meet specifications for mobile phone administration and were integrated into a mobile phone data-capture system. Content validity and usability were assessed iteratively in four rounds of cognitive interviews with patients (n = 21) and healthcare professionals (n = 4). Reliability was examined using a test–retest. Focus group analyses yielded six areas covered by 16 items. The cognitive interviews showed satisfactory item comprehension, relevance and coverage; however, one item was added. The mobile phone self-report system was reliable and perceived easy to use. The mobile phone self-report system appears efficiently to capture information relevant in patients’ self-management of hypertension. Future studies need to evaluate the effectiveness of this tool in improving self-management of hypertension in clinical practice.

TL;DR: Routine application of ABPM in RTRs may be plausible, particularly in R TRs with deceased donor type, and transplantation from a deceased donor may be a predictor of MHT.
Abstract: Purpose: Arterial hypertension is a risk factor affecting graft function in renal transplant recipients (RTRs). In pediatric RTRs, high prevalence of masked and nocturnal hypertension was reported. Most of the RTRs had a history of hypertension and some of them were normotensive at outpatient visits whereas home blood pressure (BP) levels were higher. Masked hypertension (MHT) is defined as a normal office BP but an elevated ambulatory BP. Previous reports have demonstrated the detrimental role of MHT in clinical outcomes in hypertensive patients. However, the true prevalence of MHT in RTRs is yet to be defined. Methods: A total of 113 RTRs (mean age 44 ± 16 years, 72 males, 41 females) with normal office BP (< 140/90 mmHg) were enrolled to the study from the outpatient renal transplantation clinic. Ambulatory BP monitoring (ABPM) was performed in all participants for a 24-h period. Average daytime BP values above 135 mmHg systolic and 85 mmHg diastolic were defined as MHT. Results: The prevalence...

TL;DR: An important role of adiponectin is suggested in increased LVM/h2.7 in visceral obesity-associated normotensive and hypertensive subjects and, more than blood pressure, may be able to explain the development of cardiac damage.
Abstract: This study has been designed to evaluate the impact of adiponectin levels on left ventricular geometry and function in visceral obesity-associated hypertension. 94 consecutive subjects, 53 of them were hypertensives and 41 normotensives with age ≤ 65 years, subgrouped according to the presence or absence of visceral obesity, were studied. Total adiponectin levels were measured by a validated competitive radioimmunoassay. Left ventricular telediastolic internal diameter, interventricular septum, posterior wall thickness, total left ventricular mass (LVM) and normalized for height to the 2.7 power (LVM/h(2.7)), relative wall thickness, left ventricular ejection fraction by echocardiography and isovolumic relaxation time, E/A ratio and deceleration time of E velocity, by pulsed-wave Doppler, were calculated. Plasma adiponectin levels were significantly lower in visceral obesity-associated hypertensives than lean hypertensives (p < 0.001) and in lean normotensives (p < 0.001). LVM and LVM/h(2.7) were significantly (p < 0.05) higher in both hypertensive groups, and in visceral obesity-associated normotensives in comparison with lean normotensives. Adiponectin levels correlated inversely with LVM/h(2.7) but only in normotensives (adjusted R squared 0.77, p < 0.0001) and hypertensives (0.67, p < 0.0001) subjects with visceral obesity. Multiple regression analysis indicated that adiponectin levels remain significantly associated (p < 0.001) to LVM/h(2.7) also when adjusted for age, gender, body mass index, waist to hip ratio and mean blood pressure. Our data suggest an important role of adiponectin in increased LVM/h(2.7) in visceral obesity-associated normotensive and hypertensive subjects. In this last group, adiponectin, more than blood pressure, may be able to explain the development of cardiac damage.
TL;DR: hs-cTnT level is related not only to LVH but also to LV geometry in hypertensive patients, and may mediate poorer LV geometric patterns in hypertension patients.
Abstract: Background. The high-sensitivity cardiac troponin T (hs-cTnT) assay provides important prognostic information on cardiovascular diseases. Although hs-cTnT is associated with left ventricle (LV) hypertrophy (LVH), it has not been investigated in different LV geometric patterns incorporating normal LV structure and concentric remodeling in addition to LVH. Objectives. We aimed to investigate the possible association between hs-cTnT and LV geometric patterns in newly diagnosed hypertensive patients. Methods. We studied 306 patients with newly diagnosed hypertension (HT; mean age 51.7 ± 5.6 years) and 44 healthy control subjects (mean age 51.3 ± 4.7 years). Echocardiographic examination was performed in all subjects. Four different geometric patterns were determined in hypertensive patients according to LV mass index (LVMI) and relative wall thickness (RWth). hs-cTnT and other biochemical markers were measured in all participants. Results. The highest hs-cTnT values were observed in the concentric hyp...
TL;DR: Uric acid is an independent determinant of ED irrespective of blood pressure control and questioning erectile function for hypertensive patients with increased UA levels may be recommended.
Abstract: Background. Endothelial dysfunction plays a major role in erectile dysfunction (ED). Uric acid (UA) is a marker of endothelial dysfunction. We hypothesized that increased UA levels may be associated with ED and aimed to investigate whether there is a relationship between, UA and ED in hypertensive patients. Methods. A total of 200 hypertensive patients who have a normal treadmill exercise test were divided into two groups based on the Sexual Health Inventory for Men (SHIM) test (< 21 defined as ED n = 110, and ≥ 21 defined as normal erectile function n = 90). The differences between the ED and normal erectile function groups were compared and determinants of ED were analyzed. Main results. The prevalence of ED was found to be 55.0%. Office blood pressure level was comparable between groups. UA levels were significantly increased in the ED group (6.20 ± 1.56 vs 5.44 ± 1.32, p = 0.01). In a regression model, age [odds ratio (95% confidence interval): 1.08 (1.04–1.14), p = 0.001], smoking [odds ratio...
TL;DR: The results clearly illustrate the benefits of integrating PWV in the risk assessment strategies, as advocated by HeartSCORE, insofar as it contributes to a better discriminative capacity of global cardiovascular risk, particularly in individuals with low or moderate cardiovascular risk.
Abstract: Background. HeartSCORE is a tool for assessing cardiovascular risk, basing its estimates on the relative weight of conventional cardiovascular risk factors. However, new markers of cardiovascular risk have been identified, such as aortic pulse wave velocity (PWV). The purpose of this study was to evaluate to what extent the incorporation of PWV in HeartSCORE increases its discriminative power of major cardiovascular events (MACE). Methods and results. This study is a sub-analysis of the EDIVA project, which is a prospective cohort, multicenter and observational study involving 2200 individuals of Portuguese nationality (1290 men and 910 women) aged between 18 and 91 years (mean 46.33 ± 13.76 years), with annual measurements of PWV (Complior). Only participants above 35 years old were included in the present re-analysis, resulting in a population of 1709 participants. All MACE – death, cerebrovascular accident, coronary accidents (coronary heart disease), peripheral arterial disease and renal failu...
TL;DR: Cardiac index values yielded by Hotman system compares favorably with that obtained with thermodilution in cardiac patients, and the coefficients of repeatability and intraclass correlation coefficients were high and similar for the two techniques.
Abstract: Introduction. The accuracy of impedance cardiography for cardiac index assessment is matter of debate, with available studies reporting inconsistent results. Our study aimed at evaluating the agreement between measurements of cardiac index provided by a new-generation thoracic electrical bioimpedance device (Hotman System) and an invasive approach based on thermodilution in humans. Methods. Cardiac index was assessed simultaneously with thoracic electrical bioimpedance and conventional thermodilution through comparison of ficonsecutive measurements in 51 cardiac patients, hospitalized
TL;DR: Both the proportions of hospitalizations that were associated with hypertension and the adjusted annual costs of such hospitalizations nearly tripled over the past 28 years, in substantial measure due to the greatly increasing proportion of hospitalization in which hypertension was listed as a secondary diagnosis.
Abstract: Background and objective. In the USA, the prevalence of hypertension has been high and increasing in recent decades. Even so, little is known about the changes over time in hospitalizations and the economic burden associated with this epidemic. We examined hypertension-associated hospitalizations and costs from 1979 to 2006. Methods. Using the National Hospital Discharge Survey and the costs of community hospitals in the USA, we analyzed the changes in hypertension-associated hospitalizations and costs over time. We included those hospitalizations with a primary or secondary diagnosis of hypertension among patients aged 25 years and above. We examined changes in costs by adjusting them into year 2008 dollars. The costs included hospital expenses of payroll, employee benefits, professional fees and supplies. Results. From 1979–1982 to 2003–2006, the proportion of hospitalizations that were associated with hypertension (primary or secondary diagnosis) increased from 1.9% to 5.4%. Among all hypertens...
TL;DR: Investigating the association between suppression of negative emotions, control of blood pressure (BP) on ambulatory blood pressure monitoring (ABPM) and blood pressure variability (BPV) and the Courtauld Emotional Control Scale (CECS) found few significant, weak correlations were observed.
Abstract: The aim was to assess the control of negative emotions in treated patients with hypertension in comparison with normotensive individuals and to evaluate the association between suppression of negative emotions, control of blood pressure (BP) on ambulatory blood pressure monitoring (ABPM) and blood pressure variability (BPV). We studied 195 patients (women/men: 89/106); mean age 45.4 ± 15.9 years. All patients had ABPM and completed the Courtauld Emotional Control Scale (CECS). The total CECS score and scores for subscales for anger, depression and anxiety were analyzed together with mean BP values from ABPM, and their SD and coefficient of variation as BPV measures. The mean CECS score was 54 ± 12 in all subjects; highest in uncontrolled hypertension 56 ± 11, intermediate 53 ± 12 in controlled hypertension and lowest 48 ± 12 in normotensive subjects. The reference value for the Polish population is 50 ± 11. Significant differences of mean CECS scores among groups were observed (p = 0.0165) also in multivariate analysis. The difference between uncontrolled hypertension and normotension was significant (p = 0.0262). Few significant, weak correlations were observed between CECS score or its subscales and ABPM derivates in all subjects. Conclusion. Suppression of negative emotions may adversely affect BP control in treated hypertensive patients and it should be considered a cause of uncontrolled hypertension.
TL;DR: The association of hyperuricemia with hypertension was stronger in males than in females, and middle-aged men with hyperuricaemia had greater association with hypertension.
Abstract: In this study, we report the relationship between hyperuricemia and hypertension in a middle-aged Chinese population, emphasizing the difference of gender. The cross-sectional study was conducted among 1776 adults aged 45-60 years, who participated in the Hefei Nutrition and Health Study (2012). Hyperuricemia was defined as serum uric acid (SUA)> 420 μmol/l for men, and > 360 μmol/l for women. Hypertension was defined as systolic blood pressure (SBP) ≥ 140 mmHg or diastolic blood pressure (DBP) ≥ 90 mmHg. Anthropometric measurements and biochemical data were collected using standardized procedures. Multivariate logistic regression analysis was performed to determine the relationship between hyperuricemia and hypertension with adjustment of potential confounding factors. Body mass index (BMI), waist circumference (WC), SBP, DBP, fasting glucose, SUA and the prevalence of hyperuricemia and hypertension were significantly higher in male than in female (p < 0.001). Females had significantly higher levels of triglycerides (TG) and high-density lipoprotein (HDL)-cholesterol (5.23 ± 0.87 vs 5.12 ± 1.01, p < 0.05, 1.50 ± 0.37 vs 1.28 ± 0.41, respectively.) than males. Simple correlation analysis showed that SUA was positively associated with WC and TG. In addition, after adjusting for potential confounders, hyperuricemia was associated with increased risk of hypertension in both males and females, with odds ratios (95% CI) of 1.680 (1.110-2.543) and 1.065 (1.012-1.118), respectively. Conclusions: The association of hyperuricemia with hypertension was stronger in males than in females, and middle-aged men with hyperuricemia had greater association with hypertension. Our findings remain to be confirmed in future prospective studies.
TL;DR: A high prevalence of WCE is found in RHTN, and this effect may predict silent myocardial ischemia in this subset of hypertensive patients, and special attention should be given to the WCE.
Abstract: White-coat hypertension (WCH), commonly found in pseudoresistant hypertension, does not pose higher cardiovascular risk than hypertensive status. However, when the decrease of the out-of-office blood pressure does not reach normal levels - the white-coat effect (WCE) - the repercussions are still obscure. We investigated the repercussions of the WCE in myocardial perfusion in resistant hypertension (RHTN). We enrolled 129 asymptomatic RHTN subjects - divided into WCE (n = 63) and non-WCE (n = 66) - to perform rest and stress myocardial perfusion scintigraphy and biochemical tests. Groups were equal regarding age, gender and body mass index. There was a high prevalence of WCE (49%). WCE was associated with higher prevalence of myocardial ischemia (49.2% vs 7.6%, p < 0.001), microalbuminuria (60.3% vs 36.4%, p = 0.01) and higher heart rate (72 [64-80] vs 64 [60-69], p < 0.001), compared with non-WCE patients. On an adjusted logistic regression, heart rate was considered a predictor of WCE (OR = 1.10, 95% CI 1.04-1.15; p < 0.001), but not MA (OR = 1.8, 95% CI 0.8-3.9; p = 0.15). On a second model of adjusted logistic regression, WCE was an independent predictor of myocardial ischemia (OR = 14.7, 95% CI 4.8-44.8; p < 0.001). We found a high prevalence of WCE in RHTN, and this effect may predict silent myocardial ischemia in this subset of hypertensive patients. In this group of hypertensives special attention should be given to the WCE.
TL;DR: The INSPiRED trial will generate long-term efficacy and safety data, identify the subset of treatment-resistant hypertensive patients responsive to RDN, provide information on cost-effectiveness, and inform guideline committees and health policy makers.
Abstract: The SYMPLICITY studies showed that renal denervation (RDN) is feasible as novel treatment for resistant hypertension. However, RDN is a costly and invasive procedure, the long-term efficacy and safety of which has not yet been proven. Therefore, we designed the INSPiRED trial to compare the blood pressure lowering efficacy and safety of RDN vs usual medical therapy. INSPiRED is a randomized controlled trial enrolling 240 treatment-resistant hypertensive patients at 16 expert hypertension centres in Belgium. Eligible patients, aged 20-69 years old, have a 24-h ambulatory blood pressure of 130 mmHg systolic or 80 mmHg diastolic or more, while taking at least three antihypertensive drugs. They are randomized to RDN (EnligHTN(TM), SJM system) plus usual care (intervention group) or usual care alone (control group) in a ratio of 1:1. The primary endpoints for efficacy and safety, measured after 6 months, are the baseline-adjusted between-group differences in 24h systolic blood pressure and in glomerular filtration rate as estimated by the Chronic Kidney Disease Epidemiology Collaboration equation. Follow-up will continue up to 36 months after randomization. INSPiRED is powered to demonstrate a 10-mmHg difference in systolic blood pressure between randomized groups with a two-sided p-value of 0.01 and 90% power. It will generate long-term efficacy and safety data, identify the subset of treatment-resistant hypertensive patients responsive to RDN, provide information on cost-effectiveness, and by doing so INSPiRED will inform guideline committees and health policy makers.
TL;DR: The recent studies have shown a preventive effect of other antihypertensive drugs on AF occurrence and demonstrated that aggressive approach to hypertensive patients with AF is very important not only for conversion into Sinus rhythm, but also for sinus rhythm maintenance.
Abstract: Arterial hypertension and atrial fibrillation (AF) are very prevalent cardiovascular diseases, commonly seen together. Considering the fact that frequency of these medical conditions is constantly increasing due to human life extension, AF will be one of the major risks of cardiovascular morbidity and mortality in the future. Several pathophysiological mechanisms have been proposed to explain the onset of AF in arterial hypertension, and there are numerous theories that explain the protective effect of renin-angiotensin-aldosterone system (RAAS) blockade on new-onset AF. However, the consensus on pathophysiology and the favorable effect of RAAS blockade on AF development is still missing. On the other hand, large clinical trials and meta-analyses demonstrated a positive effect of angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers on AF prevention, which is why these drugs are included in the current guidelines for arterial hypertension, and will probably be better positioned in the new guidelines, which will be published this year. The recent studies have also shown a preventive effect of other antihypertensive drugs on AF occurrence and demonstrated that aggressive approach to hypertensive patients with AF is very important not only for conversion into sinus rhythm, but also for sinus rhythm maintenance.
TL;DR: It is suggested that persistence of LVH in a subset of patients with mean in-treatment SBP ≤ 130 mmHg randomly assigned to losartan- or atenolol-based treatment may explain the lack of benefit found in hypertensive patients despite treatment to lower SBP.
Abstract: Aim. To determine if persistence of electrocardiographic (ECG) left ventricular hypertrophy (LVH) during aggressive systolic blood pressure (SBP) lowering would identify patients at increased risk. Methods and results. Adjudicated outcomes were examined in relation to the presence of LVH by mean in-treatment Cornell product (CP) in 463 hypertensive patients with mean in-treatment SBP ≤ 130 mmHg randomly assigned to losartan- or atenolol-based treatment. During mean follow-up of 4.4 ± 1.3 years, persistence of mean CP > 2440 mm ms in 211 patients (45.6%) was associated with significantly higher 4-year rates of cardiovascular death (8.9% vs 3.4%, p = 0.003), myocardial infarction (7.0% vs 3.3%, p = 0.010), stroke (8.5% vs 2.1%, p = 0.002), the composite endpoint of these events (20.0% vs 7.0%, p < 0.001) and all-cause mortality (14.9% vs 10.0%, p = 0.015). In multivariate Cox analyses, adjusting for a propensity score for CP LVH, randomized treatment and Framingham risk score entered as standard cov...
TL;DR: Brachial systolic blood pressure is more closely associated with left ventricular load than brachial blood pressure, while brachIAL blood Pressure is more strongly associated with vascular damage than central blood pressure.

TL;DR: An adult case of endocrinologically active adrenal GN incidentally diagnosed in a 64-year-old male patient with history of uncontrolled hypertension is described, the second report that describes hormone-secreting pure Adrenal GN in an adult from Turkey in the English literature.
Abstract: BACKGROUND. Ganglioneuromas (GNs) are neural crest cell-derived tumors and rarely occur in the adrenal gland. They are usually asymptomatic and hormonally silent. The majority of cases are detected incidentally during work-up for unrelated conditions. Hormone-secreting pure adrenal GNs in adults are extremely rare. To date, only four cases have been reported in the English literature. CASE REPORT. We describe an adult case of endocrinologically active adrenal GN incidentally diagnosed in a 64-year-old male patient with history of uncontrolled hypertension. On physical examination, he had a blood pressure (BP) of 160/100 mmHg. Abdominal computed tomography and magnetic resonance imaging showed a large solid tumor (8.5 × 7.5 × 7 cm) in the right adrenal gland. Urinary levels of norepinephrine, normetanephrine, vanillylmandelic acid and dopamin were elevated, although urinary level of epinephrine was suppressed. Right adrenalectomy was performed for treatment purposes. The histological diagnosis of the resected tumor was adrenal GN. CONCLUSIONS. Hormone-secreting pure adrenal GN occurs very rarely in adults and preoperative diagnosis is difficult. Adrenal GN may present with hormonal activity such as increased secretion of catecholamines and their metabolites. There are no specific diagnostic signs and symptoms discriminating GN and pheochromocytoma. Therefore, histopathological examination need for a definitive diagnosis of adrenal GN. The prognosis after completed surgical resection without further therapy seems to be excellent. To our knowledge, the present case is the second report that describes hormone-secreting pure adrenal GN in an adult from Turkey in the English literature. We discuss this case and review the literature on this unusual entity.
TL;DR: The prevalence of ISH in Xinjiang is higher than average and exhibits a gender difference, and populations with obesity, diabetes or dyslipidemia, and patients who have hypertension combined with obesity and/or diabetes, should be aware of early preventive interventions.
Abstract: Objectives. To estimate the current prevalence and epidemiology of isolated systolic hypertension (ISH) among adult populations from different ethnic groups in Xinjiang province and to further establish a theoretical basis for developing personalized therapeutic strategies for hypertensive populations. Methods. To analyze the prevalence and risk factors of ISH in different ethnic groups in Xinjiang province, a cluster sampling method was adopted to conduct a cross-sectional study on people aged 35 years and older from the Han, Uygur and Kazakh populations in the Urumqi, Kelamayi, Hetian, Zhaosu, Fukang, Tulufan and Fuhai. Results. A total of 14,618 adults were surveyed with a response rate of 88.80%. The overall prevalence of ISH was 11.95% (men: 10.84% vs women: 12.92%); the prevalence of ISH in women was significantly higher (χ2 = 15.06, p = 0.00) than that in men. The prevalence varied significantly with age (χ2 = 822.71, p = 0.00) and increased in the elderly (χ2 = 769.59, p = 0.00). A logisti...
TL;DR: The study confirms that nebivolol produces a less pronounced impact on augmentation index than atenolol, and modified the mean augmentation Index to a lesser extent than atanolol after 10 weeks.
Abstract: Introduction. The main objective was to compare the mean change in augmentation index of hypertensive patients treated with nebivolol or atenolol. Methods. Multicenter, double-blind randomized study conducted in six Spanish centers. We enrolled outpatients between the ages of 40 and 65 years with mild or moderate essential hypertension (systolic blood pressure, SBP ≥ 140 mmHg to ≤ 179 mmHg and diastolic blood pressure, DBP ≥ 90 mmHg to ≤ 109 mmHg after a 2-week run-in placebo period). Patients received nebivolol 5 mg or atenolol 50 mg once daily. At week 3, atenolol could be titrated up to 100 mg qd for non-responders. Additionally, patients not achieving normal blood pressure after 6 weeks could be treated with 25 mg hydrochlorothiazide. Follow-up visits were at 3, 6 and 10 weeks. Results. The final study population of 138 patients (58% men; median age 52.6 years, range 40–67 years) was randomized into two groups of 69 patients each. Baseline characteristics of the two groups were similar. At the...
TL;DR: During mobilization of inpatients, leg compression seems to reduce the seating-induced postural hypotension and relevant symptoms and even in patients with persisting PH, bandaging may improve hemodynamics and attenuate associated symptoms.
Abstract: Aim. We evaluated the eventual effects of leg compression on seating-induced postural hypotension (PH) in the context of various relevant clinical variables. Methods. Included were 73 hospitalized patients with various acute conditions, aged ≥ 60 years, bedridden for ≥ 8 h, with diagnosed PH [≥ 20 mmHg systolic and/or ≥ 10 mmHg diastolic blood pressure (BP) falls] at the first seating. BP, heart rhythm, dizziness and palpitations were recorded before and during 5 min of sitting. The next day, the patients were reevaluated, this time using compression bandages applied along both legs before seating. Results. Compared with the non-bandaged state, PH was registered in only 53% of bandaged patients (p < 0.001). Moreover, the appearance of PH symptoms decreased (p < 0.001). On the second day (bandaged), supine diastolic BP values were higher in the persisting vs non-persisting PH group (p = 0.027). In the bandaged state, PH symptoms were significantly reduced in the non-persisting PH group (p = 0.003)....
TL;DR: A typical clinical case of licorice abuse is reported to emphasize the importance of a detailed anamnesis, which is essential for the diagnosis, avoid unnecessary and expensive investigations, and reduce the duration of hospitalization.
Abstract: The glicyrrhizic acid, contained in licorice, has a mineralcorticoid-like effect. Chronic excess intake of licorice induces the rare syndrome of "apparent mineralcorticoid excess", due to the inhibitory effect of glicyrrhizic acid on 11 β-hydroxysteroid dehydrogenase type 2 determining clinical/biochemical manifestations as resistant hypertension, metabolic alkalosis and severe hypokalemia. We report a typical clinical case of licorice abuse to emphasize the importance of a detailed anamnesis, which is essential for the diagnosis, avoid unnecessary and expensive investigations, and reduce the duration of hospitalization. We also provide an appraisal of the pathophysiology of "apparent mineralcorticoid excess" syndrome, still an often forgotten or unrecognized cause of hypokalemia and hypertension.
TL;DR: LV and LA mechanics, as well as functional capacity are significantly impaired in the subjects with high-normal BP, and LV and LA myocardial deformations are associated with peak oxygen uptake.
Abstract: Objective. To evaluate the relationship between functional capacity and left ventricular (LV) and left atrial (LA) myocardial deformation, assessed by two- and three-dimensional (2DE and 3DE) strain analysis, in subjects with high-normal blood pressure (BP). Methods. This cross-sectional study included 64 subjects with optimal BP and 75 subjects with high-normal BP of similar gender and age. All the subjects underwent a complete 2DE and 3DE examination and cardiopulmonary exercise testing. Results. 3DE global longitudinal strain was significantly lower in the group with high-normal BP than in the optimal BP group (− 20.1 ± 2.4 vs − 18.5 ± 2.3%, p < 0.001). Similar results were obtained for 3DE global circumferential strain (− 21.8 ± 2.6 vs − 19.3 ± 2.4%, p < 0.001), as well as for 3DE global radial strain (45.1 ± 8.8 vs 42.3 ± 7.2%, p = 0.042), and 3DE global area strain (− 30.1 ± 4.2 vs − 28.1 ± 3.8%, p < 0.001). LV twist was similar between the observed groups, whereas untwisting rate was signif...
TL;DR: It is found that among Chinese nonagenarians/centenarians, heavy smoking (current or former) could increase diastolic blood pressure and prevalence of diastsolic hypertension, but was not associated with changes in systolic blood blood pressure.
Abstract: Objective. Cigarette smoking has been confirmed as a factor influencing arterial blood pressure. In the present study, we studied whether cigarette smoking habits were still associated with arterial blood pressure among Chinese nonagenarians/centenarians. Methods. The present study analyzed data from a survey conducted on all residents aged 90 years or more in the DuJiangYan district (in total 2,311,709 inhabitants) in 2005. Results. The individuals included in the statistical analysis were 216 men and 445 women. Individuals who were heavy smokers (76.62 ± 13.28 mmHg) had higher diastolic blood pressure, compared with medium and light smokers (72.33 ± 12.98 and 70.28 ± 10.31 mmHg) (F = 3.551, p = 0.030). There was a higher prevalence of diastolic hypertension (21.62% vs 5.75% and 7.14%, χ2 = 6.302, p = 0.043). Furthermore, there was a higher risk for diastolic hypertension in heavy smokers (OR = 3.886, 95% CI 1.241–12.161) (adjusted) compared with medium (OR = 1.475, 95% CI 0.599–3.360) and light ...
