Huang YH, Lee TH, Ting CW. Exploring the relationship between admission pulse pressure and clinical features in patients with spontaneous supratentorial intracerebral hemorrhage. Neurosurg Rev 2023; 47:19. [PMID: 38135792 DOI: 10.1007/s10143-023-02256-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 12/14/2023] [Accepted: 12/18/2023] [Indexed: 12/24/2023]
Abstract
Elevated pulse pressure is commonly observed in cardiovascular diseases and serves as an independent risk factor and predictor of cardiac mortality. However, the role of pulse pressure in patients with spontaneous intracerebral hemorrhage (ICH) remains uncertain. This study aimed to investigate the association between admission pulse pressure and clinical characteristics, including in-hospital outcomes, in ICH patients. We retrospectively analyzed the data of 292 ICH patients, categorizing them into two groups based on admission wide pulse pressure: > 100 mmHg (n = 60) and ≤ 100 mmHg (n = 232). Clinical characteristics and in-hospital outcomes were compared between the groups, and multivariate logistic regression was performed to identify independent factors. Patients with wide pulse pressure were older, had lower Glasgow Coma Scale, larger intraparenchymal hematomas, more pronounced midline shifts, and higher rates of intraventricular hematoma extension and hydrocephalus. These patients also experienced higher frequencies of craniotomy or craniectomy and longer hospital stays. Multivariate logistic regression revealed that pulse pressure > 100 mmHg was significantly associated with increased in-hospital mortality (odds ratio 4.31, 95% confidence interval 1.12-16.62, p = 0.03), but not with a modified Rankin Scale score of 4-6. In conclusion, our investigation demonstrates a significant relationship between admission pulse pressure and severe clinical characteristics in ICH patients. Importantly, a wider pulse pressure is linked to heightened in-hospital mortality. These results underscore the necessity for customized strategies to predict patient outcomes in this population. Further research is essential to explore potential therapeutic interventions targeting pulse pressure to improve clinical outcomes for ICH patients.

Pulse pressure and its association with body composition among Chinese men and women without diagnosed hypertension: the China Kadoorie Biobank. J Hypertens 2023; 41:1802-1810. [PMID: 37682069 PMCID: PMC10552820 DOI: 10.1097/hjh.0000000000003549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 08/02/2023] [Accepted: 08/07/2023] [Indexed: 09/09/2023]
Abstract
BACKGROUND Wide brachial pulse pressure (PP) has been associated with cardiovascular events, while its population distribution and association with body composition were poorly characterized in large populations. METHODS We evaluated the age and sex distributions of PP and its associations with body composition using baseline data from the China Kadoorie Biobank. A total of 434 200 participants without diagnosed hypertension were included in the analysis. Wide PP was defined as PP above 65 mmHg. Body composition variables, including BMI, waist circumference, waist-to-hip ratio (WHR), fat mass index (FMI), fat-free mass index (FFMI), and body fat percentage (BF%), were obtained from bioelectrical impedance analysis. RESULTS Overall, 14.3% of the participants had wide PP. Older age was consistently associated with wider PP in women but only after the andropause stage in men. The independent associations of BMI with wide PP were stronger than other body composition measures. The adjusted differences (men/women, mmHg) in PP per standard deviation (SD) increase in BMI (1.55/1.47) were higher than other body composition (BF%: 0.32/0.64, waist circumference: 0.33/0.39; WHR: 0.49/0.42). In addition, sex differences were observed. In men, the per SD difference in PP was higher for FFMI than for FMI (0.91 vs. 0.67, P < 0.05), whereas in women, it was higher for FMI than for FFMI (1.01 vs. 0.72, P < 0.05). CONCLUSION Our nationwide population-based study presented the sex-specific distribution of PP over age and identified differential associations of PP with fat and fat-free mass in men and women.

Abstract
BACKGROUND AND AIMS Among an unselected cohort of men and women from general population (n = 1.668), the prognostic effects of being over the cut-off of all-source dietary caffeine intake were studied. METHODS AND RESULTS Prognostic cut-off values for coronary events, incident heart failure (HF), cerebrovascular events (CBV) and arrhythmic events (ARR) were found by means of the receiver-operating-characteristic curves method. Those for HF (>230 mg/day), for CBV (>280 mg/day) and for ARR (>280 mg/day) were confirmed in multivariate Cox analysis adjusted for age, body mass index, circulating thyroid hormone, diabetes mellitus, arterial hypertension, smoking, dietary intake of ethanol, basal heart rate, low-density-lipoprotein cholesterol, forced expiratory volume in 1 s and β-blocking therapy. Being over these cut-off values was associated to a reduced hazard ratio during the follow-up in the whole cohort (HR 0.678, 95%CI 0.567-0.908, p = 0.009 for HF; 0.651, 95%CI 0.428-0.994, p = 0.018 for CBV; 0.395, 95%CI 0.395-0.933, p = 0.022 for ARR) and in men (0.652, 0.442-0.961, p = 0.029; 0.432, 0.201-0.927, p = 0.03; 0.553, 0.302-1.000, p = 0.05, respectively) but not in women. The caffeine-induced risk decrease observed in the whole cohort is therefore entirely attributable to men. In the case of HF, heart rate entered the risk equation in a positive manner without rejecting caffeine. The -163C>A polymorphism of the CYP1A2 gene, codifying for ability to metabolize caffeine, introduced in sensitivity analysis, did not alter the prognostic models. CONCLUSION Men introducing >230 mg/day caffeine show a reduced risk of HF, and those introducing >280 mg/day a reduced risk of CBV and ARR independent of genetic pattern.

Abstract
AIM Although systolic and diastolic blood pressures as well as blood glucose are monitored when nurses care for patients with type 2 diabetes, the same is not true for pulse pressure. We aimed to determine the association between pulse pressure and all-cause mortality. METHODS We conducted a longitudinal study of outpatients with type 2 diabetes aged 65 years and older at diabetes-specialized hospitals in Japan from September 2004 to December 2016. Descriptive data, blood pressure measurements, blood analysis data, and information on life and death were obtained from medical records. Cox proportional hazards models were used to estimate the relative risks with 95% confidence intervals for all-cause mortality. RESULTS We analyzed 357 of the 383 recruited patients (mean age, 74.9 years; 175 men and 182 women; average follow-up, 7.7 years), and 50 patients died. After adjusting for covariates, the relative risks for pulse pressures of 55 to <65, 65 to <75, and ≥75 mmHg (reference: <55 mmHg) were 1.77 (95% confidence interval: [0.59, 5.28]), 2.66 (95% confidence interval: [0.93, 7.56]), and 3.23 (95% confidence interval: [1.16, 8.99]), respectively. The relative risk for the 65 mmHg or higher group (reference: <65 mmHg) was 2.08 (95% confidence interval: [1.11, 3.92]). Neither systolic blood pressure nor diastolic blood pressure alone were significantly associated with mortality. CONCLUSIONS In older patients with type 2 diabetes, a wide pulse pressure was associated with a higher risk of all-cause mortality. Nurses caring for older people with diabetes should also monitor pulse pressure.

Cardiovascular outcomes and achieved blood pressure in patients with and without diabetes at high cardiovascular risk. Eur Heart J 2020; 40:2032-2043.

Abstract
AIMS Studies have shown a non-linear relationship between systolic blood pressure (SBP) and diastolic blood pressure (DBP) and outcomes, with increased risk observed at both low and high blood pressure (BP) levels. We hypothesized that the BP-risk association is different in individuals with and without diabetes at high cardiovascular risk. METHODS AND RESULTS We identified patients with (N = 11 487) or without diabetes (N = 19 450), from 30 937 patients, from 133 centres in 44 countries with a median follow-up of 56 months in the ONTARGET/TRANSCEND studies. Patients had a prior history of stroke, myocardial infarction (MI), peripheral artery disease, or were high-risk diabetics. Patients in ONTARGET had been randomized to ramipril 10 mg daily, telmisartan 80 mg daily, or the combination of both. Patients in TRANSCEND were ACE intolerant and randomized to telmisartan 80 mg daily or matching placebo. We analysed the association of mean achieved in-trial SBP and DBP with the composite outcome of cardiovascular death, MI, stroke and hospitalization for congestive heart failure (CHF), the components of the composite, and all-cause death. Data were analysed by Cox regression and restricted cubic splines, adjusting for risk markers including treatment allocation and accompanying cardiovascular treatments. In patients with diabetes, event rates were higher across the whole spectrum of SBP and DBP compared with those without diabetes (P < 0.0001 for the primary composite outcome, P < 0.01 for all other endpoints). Mean achieved in-trial SBP ≥160 mmHg was associated with increased risk for the primary outcome [diabetes/no diabetes: adjusted hazard ratio (HR) 2.31 (1.93-2.76)/1.66 (1.36-2.02) compared with non-diabetics with SBP 120 to <140 mmHg], with similar findings for all other endpoints in patients with diabetes, and for MI and stroke in patients without diabetes. In-trial SBP <120 mmHg was associated with increased risk for the combined outcome in patients with diabetes [HR 1.53 (1.27-1.85)], and for cardiovascular death and all-cause death in all patients. In-trial DBP ≥90 mmHg was associated with increased risk for the primary outcome [diabetes/no diabetes: HR 2.32 (1.91-2.82)/1.61 (1.35-1.93) compared with non-diabetics with DBP 70 to <80 mmHg], with similar findings for all other endpoints, but not for CHF hospitalizations in patients without diabetes. In-trial DBP <70 mmHg was associated with increased risk for the combined outcome in all patients [diabetes/no diabetes: HR 1.77 (1.51-2.06)/1.30 (1.16-1.46)], and also for all other endpoints except stroke. CONCLUSION High on treatment BP levels (≥160 or ≥90 mmHg) are associated with increased risk of cardiovascular outcomes and death. Also low levels (<120 or <70 mmHg) are associated with increased cardiovascular outcomes (except stroke) and death. Patients with diabetes have consistently higher risks over the whole BP range, indicating that achieving optimal BP goals is most impactful in this group. These data favour guidelines taking lower BP boundaries into consideration, in particular in diabetes. CLINICAL TRIAL REGISTRATION http://clinicaltrials.gov.Unique identifier: NCT00153101.

Abstract
INTRODUCTION The effect of metabolic syndrome (MS) on carotid stiffness (CS) in the context of gender is under research. OBJECTIVE We examined the relationship between the MS and CS in men (M) and women (W) and investigated if the impact of cardiovascular risk factors on CS is modulated by gender. PATIENTS AND METHODS The study included 419 subjects (mean age 54.3 years): 215 (51%) with MS (109 W and 106 M) and 204 (49%) without MS (98 W and 106 M). Carotid intima-media thickness (IMT) and CS parameters (beta stiffness index (beta), Peterson's elastic modulus (Ep), arterial compliance (AC) and one-point pulse wave velocity (PWV-beta)) were measured with the echo-tracking (eT) system. RESULTS ANCOVA demonstrated that MS was associated with elevated CS indices (p = 0.003 for beta and 0.025 for PWV-beta), although further sex-specific analysis revealed that this relationship was significant only in W (p = 0.021 for beta). Age was associated with CS in both M and W, pulse pressure (PP) and body mass index turned out to be determinants of CS solely in W, while the effect of mean arterial pressure (MAP) and heart rate was more pronounced in M. MANOVA performed in subjects with MS revealed that age and diabetes mellitus type 2 were determinants of CS in both sexes, diastolic blood pressure and MAP - solely in M and systolic blood pressure, PP and waist circumference - solely in W (the relationship between the waist circumference and AC was paradoxical). CONCLUSION The relationship between MS and CS is stronger in W than in M. In subjects with MS, various components of arterial pressure exert different sex-specific effects on CS - with the impact of the pulsative component of arterial pressure (PP) observed in W and the impact of the steady component (MAP) observed in M.

The effects of blood pressure components on cardiovascular events in a Korean hypertensive population according to age and sex: A nationwide population-based cohort study.

Abstract
There is no known study regarding the usefulness of each blood pressure (BP) component based on stratification by age and sex for predicting cardiovascular (CV) events among hypertensive populations without chronic kidney disease (CKD) or diabetes mellitus (DM). This study was performed to investigate the association of BP components and CV events in a Korean hypertensive population according to age and sex. A total of 22,853 Korean hypertensive participants without CKD and DM were stratified into six groups according to age [40-49, 50-59, and 60 years or older] and sex. In each group, multivariate Cox proportional regression analysis was performed to reveal the associations of BP components [systolic BP (SBP), diastolic BP (DBP), mean arterial pressure (MAP) and pulse pressure (PP)] with CV events. The increase in PP and decrease in DBP were significantly associated with increase of CV events in males, but neither BP component was significantly associated with risk of CV events in females. When subjects were stratified by age and sex, an increase of SBP or PP was significantly related to the increased risk of CV events in 40's male group, and only the elevation of PP was significantly associated with increase in incidence of CV events in 50's male group, while a decrease in DBP was significantly associated with increased risk of CV events in older male group. In addition, there were no the significant associations with the incidence of CV events in MAP, after stratification according to age and sex. In conclusion, this study suggests that, in hypertensive populations, BP management may need to be performed after full consideration of age and sex.

Abstract
OBJECTIVE Accumulation of reactive oxygen species by increased uric acid production has been suggested as a possible underlying mechanism for the association between uric acid and high blood pressure (BP). We, therefore, investigated the association between serum uric acid concentration and 24-h urinary uric acid excretion, as proxy for uric acid production, with ambulatory 24-h blood pressure and hypertension. METHODS Cross-sectional analyses were conducted among 2555 individuals [52% men, mean age 60.0 ± 8.2 years; 27% type 2 diabetes (by design)] from The Maastricht Study. Multivariable regression analyses were performed to investigate the association of serum uric acid and 24-h urinary uric acid excretion with 24-h pulse pressure, 24-h mean arterial pressure (MAP), and hypertension. RESULTS After adjustment for traditional hypertension risk factors, serum uric acid concentration (per SD of 81 μmol/l) was associated with higher 24-h MAP [β 0.63 mmHg; confidence interval (CI) 0.27-1.00] and positively associated with hypertension (odds ratio 1.43; CI 1.27-1.61). Urinary uric acid excretion (per SD of 140 mg/day/1.73 m) was associated with higher 24-h MAP (β 0.79 mmHg; CI 0.46-1.12) and with hypertension (odds ratio 1.13; CI 1.02-1.25). There was no significant association between serum and 24-h urinary uric acid excretion with 24-h pulse pressure. There was no interaction with sex or age for the aforementioned associations. CONCLUSION Higher serum and urinary uric acid concentrations were associated with higher 24-h MAP and hypertension. These results suggest that serum and 24-urinary uric acid concentrations, the latter as proxy for uric acid production are, independent of each other, associated with BP and hypertension.

Fixed-Dose Triple Combination of Antihypertensive Drugs Improves Blood Pressure Control: From Clinical Trials to Clinical Practice. Adv Ther 2017; 34:975-985.

Abstract
INTRODUCTION Blood pressure (BP) control is the main clinical goal in the management of hypertensive patients; however, BP in most of these patients remains uncontrolled, despite the widespread availability of antihypertensive drugs as free-combination therapy. This study compared the efficacy of a fixed-dose triple combination (FDTC) of antihypertensive drugs with that of a free combination of three antihypertensives in patients with uncontrolled hypertension. METHODS Ninety-two patients (mean age 60.8 ± 12.1, 58.0% male) with uncontrolled essential hypertension (office systolic BP ≥ 140 or diastolic BP ≥ 90 mmHg) previously treated with a renin-angiotensin-aldosterone system (RAAS) inhibitor plus hydrochlorothiazide were switched to once-daily FDTC therapy with perindopril/indapamide/amlodipine (5-10/1.25-2.5/5-10 mg). Patients were age- and sex-matched with a control group of hypertensive patients receiving free-combination therapy with three drugs including a RAAS inhibitor, a diuretic, and a calcium channel blocker. Office BP and 24-h ambulatory BP monitoring (ABPM) were evaluated at baseline and after 1 and 4 months. RESULTS Significant reductions in ambulatory 24-h, daytime, and nighttime systolic BP, and pulse pressure (PP) were found in the FDTC group relative to reductions seen with free-combination therapy, after the first month only of follow-up. Target BP values (mean 24-h ambulatory systolic/diastolic BP < 130/80 mmHg) were reached by more recipients of FDTC than free-combination therapy (64.8% vs. 46.9%, p < 0.05) at month 4 of follow-up, despite reductions in 24-h ABPM values from baseline being similar in both groups at this time point. CONCLUSION FDTC of perindopril/indapamide/amlodipine was effective at reducing SBP and PP in previously treated patients with uncontrolled hypertension, and well tolerated, providing support for clinicians in choosing a fixed-dose triple combination over the free-combination of a RAAS inhibitor, a diuretic, and a calcium antagonist.

Abstract
Recent and powerful epidemiological studies have been used as a basis for revising international and domestic guidelines for human exposure to mercury. Long-range transport of mercury into the Arctic makes some Arctic peoples consuming traditional marine foods, especially newborns, children and pregnant women, very vulnerable to harmful exposures. The WHO, the USEPA and Health Canada have all recently revised their mercury intake guidelines as a result of neurological effects reported in children exposed in utero and adults. Guidance values are equivalent to 0.23 microg/kg-bw/d, 0.1 microg/kg-bw/d and 0.2 microg/kg-bw/d respectively. Differences between the numbers represent slight differences in the uncertainty factors applied, rather than in toxicological interpretation. More recent findings suggest that mercury may also be a factor in ischemic heart disease, which could lower guidance values in the future. Considering the benefits of marine fatty acids (n-3 fatty acids) and guidance that populations consume 300-400g fish/week, consumers face a reality that most open ocean and relatively 'unpolluted' fish species contain levels of mercury that would lead to exposures at current guidance levels. Clearly, there is no more room for further mercury pollution and there is an urgent need for international action to reduce mercury emissions. Concomitantly, while there may be a need for public health authorities to provide consumption advisories to some highly exposed populations, such as in the Arctic, there remains a need to better understand the interactions and benefits associated with marine foods that may reduce health risks associated with low-level mercury exposure.

Abstract
The reliability of blood pressure measurement with wrist devices, which has not previously been assessed under real-life circumstances in general population, is dependent on correct positioning of the wrist device at heart level. We determined whether an error was present when blood pressure was self-measured at the wrist in 721 unselected subjects from the general population. After training, blood pressure was measured in the office and self-measured at home with an upper-arm device (the UA-767 Plus) and a wrist device (the UB-542, not provided with a position sensor). The upper-arm−wrist blood pressure difference detected in the office was used as the reference measurement. The discrepancy between office and home differences was the home measurement error. In the office, systolic blood pressure was 2.5% lower at wrist than at arm (
P
=0.002), whereas at home, systolic and diastolic blood pressures were higher at wrist than at arm (+5.6% and +5.4%, respectively;
P
<0.0001 for both); 621 subjects had home measurement error of at least ±5 mm Hg and 455 of at least ±10 mm Hg (bad measurers). In multivariable linear regression, a lower cognitive pattern independently determined both the systolic and the diastolic home measurement error and a longer forearm the systolic error only. This was confirmed by logistic regression having bad measurers as dependent variable. The use of wrist devices for home self-measurement, therefore, leads to frequent detection of falsely elevated blood pressure values likely because of a poor memory and rendition of the instructions, leading to the wrong position of the wrist.

Abstract
This study was performed to investigate the association between brachial pulse pressure (PP) and the presence/extent of obstructive coronary artery disease (CAD) in men and women. Study data were obtained from a nation-wide registry composed of 632 patients (173 men and 459 women, 58.1±10.5 years) with suspected CAD who underwent invasive coronary angiography. PP was higher in patients with obstructive CAD (≥50% stenosis) than those without CAD in both sexes (P=.032 in men; P<.001 in women). However, PP increased proportionally with the increasing number of obstructed coronary arteries in women (P<.001) but not in men (P=.070). Multiple logistic-regression analyses demonstrated that higher PP (≥50.5 mm Hg) was an independent factor for determining obstructive CAD even after controlling for potential confounders in women (odds ratio, 2.83; 95% confidence interval, 1.40-5.73; P=.004). These results were consistent in 173 selected women matched with 173 men based on age and CAD severity. In conclusion, the association between brachial PP and obstructive CAD was more pronounced in women than in men. Brachial PP can be a simple and useful indicator of CAD especially in women.

Abstract
BACKGROUND The epidemiology of cardiovascular risk (CV) in the elderly is far from being defined, and the reasons why some subjects retain a healthy body while growing old while others are affected by different diseases or die prematurely are still unknown. AIMS To compare the CV risk pattern in two elderly cohorts living in North-East Italy. MATERIALS AND METHODS The Risk Of Vascular complications: Impact of Genetics in Old people (ROVIGO) study is a population-based study including 580 unrelated elderly subjects representative of general population living in Rovigo in the Veneto region. They were compared to a cohort of 580 age-gender-matched unrelated subjects from the CArdiovascular STudy in the Elderly (CASTEL) living in the same region in Castelfranco Veneto and Chioggia. RESULTS Blood pressure (BP), heart rate (HR), low-density-lipoprotein cholesterol, and prevalence of coronary heart disease, heart failure and chronic pulmonary disease were lower in the ROVIGO than in the CASTEL cohort, while high-density-lipoprotein cholesterol and the prevalence of diabetes were higher in the former than in the latter. In the ROVIGO cohort, diabetes, left ventricular hypertrophy, coronary and cerebrovascular diseases were more represented in men. In the CASTEL cohort, systolic BP was higher in women. In both cohorts, the lipid pattern was less favourable and HR higher in women, chronic pulmonary disease more represented in men. CONCLUSIONS People living in Rovigo were at lower CV risk than those in Castelfranco Veneto and Chioggia, mainly due to lower BP values, better lipid pattern and lower prevalence of CV and pulmonary disease.

High pulse pressure is not associated with abnormal activation of the renin-angiotensin-aldosterone system in repaired aortic coarctation. J Hum Hypertens 2014; 29:268-73.

Abstract
We investigated the relationship between pulse pressure (PP)--a surrogate marker of arterial stiffness-and activity of the renin-angiotensin-aldosterone system (RAAS) in adult patients with repaired coarctation and normal left ventricular (LV) function. A total of 114 patients (44 (26-74) years, 13 (0.1-40) years at repair) and 20 healthy controls were examined with 24-h ambulatory blood pressure monitoring, echocardiography, vasoactive hormone levels and magnetic resonance of the thoracic aorta. Forty-one patients (36%) were taking antihypertensives (28 RAAS inhibitors). Fifty-one had mean 24-h blood pressures >130/80 mm Hg. Hypertension was not associated with age at repair (P=0.257). Patients had higher PP and LV mass compared with controls (52±11 vs. 45±5 mm Hg and 221±71 vs. 154±55 g, respectively; both P<0.05). Differences were more pronounced in the presence of recoarctation, but independently of RAA levels. Even normotensive patients had higher LV mass than controls. LV mass and recoarctation were correlated with PP levels. In conclusion, adult patients with repaired coarctation have increased PP and LV mass compared with controls. PP increased with increasing recoarctation. Hypertension was present also in the absence of recoarctation. These changes could not be explained by abnormal activation of the RAAS.

Abstract
Dopamine D2 receptor agonists represent a first line treatment option in young patients with signs and symptoms of idiopathic Parkinson's disease. An association between the use of D2 receptor agonists in Parkinson's disease patients and heart failure has been reported. The identification of the underlying mechanism is needed to minimize the resultant cardiovascular morbidity. In a phase I clinical trial, a D2 receptor agonist (pramipexole) was administered to 52 healthy male subjects following a dose escalation scheme. Serial measurements of resting blood pressure, heart rate, and derived parameters including pulse pressure, pulsatile stress, and rate pressure product were analysed. Statistically significant and clinically relevant increases in most of the assessed parameters were found. Ten subjects were removed prematurely from the trial because of clinically significant increases in blood pressure and/or heart rate requiring immediate intervention with IV rescue medications including a selective β -1 blocker. The observed drug-related changes in vital signs were of clinical relevance and might explain some of the cardiovascular morbidity reported in patients receiving D2 receptor agonist in clinical settings. We suggest that the additional use of a β -1 blocking agent might mitigate the risk of cardiovascular morbidity among patients receiving long-term D2 receptor agonists.

Abstract
BACKGROUND Epidemiological evidence suggests a negative impact of methylmercury (MeHg) on cardiovascular risk factors such as blood pressure (BP) and heart rate (HR). This issue is of concern in Arctic populations such as in the Inuit of Nunavik since this contaminant is accumulated in fish and marine mammals, which still represent the subsistence diet of this population. OBJECTIVE We examined the associations between MeHg and BP and resting HR among Inuit adults. METHODS The "Santé Quebec" health survey was conducted in 1992 in the 14 villages of Nunavik and a complete set of data was obtained for 313 Inuit adults≥18 years. Blood samples were collected in order to determine total mercury, lead, total polychlorinated biphenyls (PCBs), n-3 polyunsaturated fatty acids (PUFAs), fasting glucose and lipid profile while socio-demographic variables were obtained through questionnaires. Anthropometric measurements as well as BP and resting HR were obtained using standardised protocols. Pulse pressure (PP: systolic BP minus diastolic BP) was also calculated. Multiple linear regression was used in order to determine the change in the dependent variables associated with the quartiles of MeHg concentration, taking the quartile 1 as reference. RESULTS The mean age of the participants was 38±14 years and the sample was composed of 132 men (42.2%) and 181 women (57.8%). MeHg geometric mean was 15.4 μg/L (95%CI: 13.9-17.0) and levels ranged from 0.8 to 112.0 μg/L. Resting HR increased linearly across quartiles of blood MeHg concentration after adjusting for confounders (p for trend=0.02). An increase of 6.9 beats per minute (bpm) between the 4th and 1st quartile was observed after adjusting for confounders. No significant association was observed between blood MeHg and systolic BP, diastolic BP or PP. CONCLUSIONS MeHg was associated with increasing resting HR after considering traditional risk factors as well as other contaminants (lead and total PCBs) and n-3 PUFAs. In contrast, no significant association with blood pressure was observed in this study.

Abstract
BACKGROUND Angiotensin receptor blockers (ARBs) are reported to provide direct protection to many organs by controlling inflammation and decreasing oxidant stress in patients without arteriosclerosis. This study aimed to evaluate (1) whether an ARB (candesartan) decreases values for inflammatory parameters in hypertensive patients with type 2 diabetes mellitus of long duration accompanied by arteriosclerosis and (2) whether there any predictors of which patients would receive the benefits of organ protection by candesartan. METHODS We administered candesartan therapy (12 mg daily) for 6 months and evaluated whether there was improvement in serum inflammatory parameters high molecular weight adiponectin (HMW-ADN), plasminogen activator inhibitor-1 (PAI-1), highly sensitive C-reactive protein (Hs-CRP), vascular cell adhesion molecule-1 (VCAM-1) in serum and urinary-8-hydroxydeoxyguanosine (U-8-OHdG). We then analyzed the relationship between the degree of lowering of blood pressure and inflammatory factors and the relationship between pulse pressure and inflammatory factors. Finally, we analyzed predictive factors in patients who received the protective benefit of candesartan. RESULTS After 6 months of treatment, significant improvements from baseline values were observed in all patients in HMW-ADN and PAI-1 but not in Hs-CRP, VCAM-1 and U-8-OHdG. Multilinear regression analysis was performed to determine which factors could best predict changes in HMW-ADN and PAI-1. Changes in blood pressure were not significant predictors of changes in metabolic factors in all patients. We found that the group with baseline pulse pressure <60 mmHg had improved HMW-ADN and PAI-1 values compared with the group with baseline pulse pressure ≥ 60 mmHg. These results suggest that pulse pressure at baseline could be predictive of changes in HMW-ADN and PAI-1. CONCLUSIONS Candesartan improved inflammatory parameters (HMW-ADN and PAI-1) in hypertensive patients with type 2 diabetes mellitus of long duration independent of blood pressure changes. Patients with pulse pressure <60 mmHg might receive protective benefits by candesartan. TRIAL REGISTRATION UMIN000007921.

Abstract
BACKGROUND The Inuit in Greenland have a high average consumption of marine species and are highly exposed to methylmercury, which in other studies has been related to hypertension. Data on the relation between methylmercury and hypertension is limited, especially in populations subjected to a high exposure of methylmercury. We examined the relation between whole blood mercury and blood pressure (BP) in Inuit in Greenland. METHODS A cross-sectional population-based study among adult Inuit in Greenland was performed in 2005-2009. Information on socio-demography, lifestyle, BP, blood samples and clinical measurements was obtained - the latter after overnight fasting. BP was measured according to standardized guidelines. Whole blood mercury concentration was used as a marker of exposure. The analyses were restricted to Inuit aged 30-69 years with four Greenlandic grandparents (N = 1,861). Multivariate regression analyses with inclusion of confounders were done separately for men and women with the omission of participants receiving anti-hypertensive drugs, except for logistic regression analyses of the relation between mercury and presence of hypertension (yes/no). RESULTS The mean whole blood mercury level was 20.5 μg/L among men and 14.7 μg/L among women. In multivariate analyses adjusted for confounders, diastolic BP decreased with increasing mercury concentration. In men diastolic BP decreased significantly for each four-fold increase in mercury concentration (Beta = -0.04, standard error = 0.01, p = 0.001), while no relation between mercury and diastolic BP was found among women. For systolic BP, a similar non-statistically significant result was seen only for men (Beta = -0.02, standard error = 0.01, p = 0.06). A relation between mercury and hypertension was only found in men; the odds ratio for hypertension was 0.99 (95% CI: 0.98-0.99). No relation between quintiles of mercury and hypertension was found. The relationship between mercury and BP parameters may be non-linear: In analyses of quintiles of mercury the overall effect of mercury on BP parameters was only statistically significant for diastolic BP among men (Wald test, p = 0.01), however pairwise comparisons showed that some quintiles were not statistically different. This result is supported by LOESS modelling. CONCLUSIONS No adverse associations between whole blood mercury and blood pressure were found. With increasing whole blood mercury concentrations, diastolic BP and the risk of hypertension decreased among men in the study: this may be explained by confounding by exercise or unknown factors.

Cognitive functions and cognitive reserve in relation to blood pressure components in a population-based cohort aged 53 to 94 years. Int J Hypertens 2012; 2012:274851.

Abstract
In 288 men and women from general population in a cross-sectional survey, all neuropsychological tests were negatively associated with age; memory and executive function were also positively related with education. The hypertensives (HT) were less efficient than the normotensives (NT) in the test of memory with interference at 10 sec (MI-10) (−33%, P = 0.03), clock drawing test (CLOX) (−28%, P < 0.01), and mini-mental state examination (MMSE) (−6%, P = 0.02). Lower MMSE, MI-10, and CLOX were predicted by higher systolic (odds ratio, OR, 0.97, P = 0.02; OR 0.98, P < 0.005; OR 0.95, P < 0.001) and higher pulse blood pressure (BP) (OR 0.97, P = 0.02; OR 0.97, P < 0.01; and 0.95, P < 0.0001). The cognitive reserve index (CRI) was 6% lower in the HT (P = 0.03) and was predicted by higher pulse BP (OR 0.82, P < 0.001). The BP vectors of lower MMSE, MI-10, and CLOX were directed towards higher values of systolic and diastolic BP, that of low CRI towards higher systolic and lower diastolic. The label of hypertension and higher values of systolic or pulse BP are associated to worse memory and executive functions. Higher diastolic BP, although insufficient to impair cognition, strengthens this association. CRI is predicted by higher systolic BP associated to lower diastolic BP.

Abstract
This review summarizes several scientific contributions at the recent Satellite Symposium of the European Society of Hypertension, held in Milan, Italy. Arterial stiffening and its hemodynamic consequences can be easily and reliably measured using a range of noninvasive techniques. However, like blood pressure (BP) measurements, arterial stiffness should be measured carefully under standardized patient conditions. Carotid-femoral pulse wave velocity has been proposed as the gold standard for arterial stiffness measurement and is a well recognized predictor of adverse cardiovascular outcome. Systolic BP and pulse pressure in the ascending aorta may be lower than pressures measured in the upper limb, especially in young individuals. A number of studies suggest closer correlation of end-organ damage with central BP than with peripheral BP, and central BP may provide additional prognostic information regarding cardiovascular risk. Moreover, BP-lowering drugs can have differential effects on central aortic pressures and hemodynamics compared with brachial BP. This may explain the greater beneficial effect provided by newer antihypertensive drugs beyond peripheral BP reduction. Although many methodological problems still hinder the wide clinical application of parameters of arterial stiffness, these will likely contribute to cardiovascular assessment and management in future clinical practice. Each of the abovementioned parameters reflects a different characteristic of the atherosclerotic process, involving functional and/or morphological changes in the vessel wall. Therefore, acquiring simultaneous measurements of different parameters of vascular function and structure could theoretically enhance the power to improve risk stratification. Continuous technological effort is necessary to refine our methods of investigation in order to detect early arterial abnormalities. Arterial stiffness and its consequences represent the great challenge of the twenty-first century for affluent countries, and "de-stiffening" will be the goal of the next decades.

Abstract
Aboriginal populations from Quebec (Canada) are exposed to higher mercury levels than southern regions since these populations consume high quantities of fish. Epidemiological evidence suggests a detrimental impact of mercury on cardiovascular risk factors such as heart rate variability (HRV) and blood pressure (BP). The objective of this study was to assess the impact of mercury exposure on BP, resting heart rate (HR) and HRV among Cree adults. Data were collected among 791 adults≥18 years old living in seven communities of the James Bay. Blood mercury and hair levels were used as biomarkers of recent and long-term exposure. BP was measured through a standardised protocol while HRV was derived from a 2-h Holter monitoring assessment. The relationship between mercury and the outcomes was studied using ANOVA and ANCOVA analysis. Geometric mean of blood mercury and hair mercury concentration was 17.0 nmol/L (95%CI: 6.1-44.0) and 2.36 nmol/g (95%CI: 2.09-2.65); respectively. After adjusting for confounders, blood mercury was associated with HRV parameters such as LF (β=0.21, P=0.0002), HF (β=0.15, P=0.004) and LF/HF (β=0.06, P=0.003). Similar associations were observed with hair mercury. In contrast, no significant association was observed between blood mercury or hair mercury and BP after adjusting for confounders. In conclusion, mercury exposure seems to affect HRV among Cree adults even after considering fish nutrients (n-3 fatty acids and selenium) and other contaminants (lead and polychlorinated biphenyls) that are also present in the traditional diet of this population.

Abstract
BACKGROUND AND AIMS A blood glucose (BG) fall after an oral glucose load has never been described previously at a population level. This study was aimed at looking for a plasma glucose trend after an oral glucose load for possible blood glucose fall if any, and for its impact on coronary mortality at a population level. METHODS AND RESULTS In subjects from an unselected general population, BG and insulin were detected before and 1 and 2h after a 75-g oral glucose load for insulin sensitivity and β-cell function determination. Blood pressure, blood examinations and left ventricular mass were measured, and mortality was monitored for 18.8±7.7 years. According to discriminant analysis, the population was stratified into cluster 0 (1-h BG < fasting BG; n=497) and cluster 1 (1-h BG ≥ fasting BG; n=1733). To avoid any interference of age and sex, statistical analysis was limited to two age-gender-matched cohorts of 490 subjects from each cluster (n=940). Subjects in cluster 0 showed significantly higher insulin sensitivity and β-cell function, lower visceral adiposity and lower blood pressure values. Adjusted coronary mortality was 8 times lower in cluster 0 than 1 (p<0.001). The relative risk of belonging to cluster 1 was 5.40 (95% CI 2.22-13.1). CONCLUSION It seems that two clusters exist in the general population with respect to their response to an oral glucose load, independent of age and gender. Subjects who respond with a BG decrease could represent a privileged sub-population, where insulin sensitivity and β-cell function are better, some risk factors are less prevalent, and coronary mortality is lower.

Abstract
AIMS To ascertain whether chronic obstructive pulmonary disease (COPD) is an independent risk factor for cardiovascular (CV) mortality in the elderly subjects from general population. METHODS 3282 subjects of the Northern Italy aged > or =65 years were followed up for 12 years in the frame of the CArdiovascular STtudy in the ELderly. Multivariate stepwise proportional hazard Cox regression was therefore used to identify the prognostic role of COPD on CV mortality in hypertensive (HT) and normotensive (NT) subjects. The hazard ratio (HR) of COPD with 95% confidence interval (CI) for mortality was adjusted for confounders in both genders. RESULTS COPD resulted to be an independent predictor of CV mortality (HR 1.34, CI 1.13-1.61) in HT but not in NT subjects. This was evident both in men (HR 1.44, 1.25-1.95) and women (HR 1.32, CI 1.14-1.53); pulse pressure (PP) was directly related and anti-hypertensive therapy inversely related to risk of CV mortality, an association that was greater in subjects with than without COPD. CONCLUSION COPD should be included in the computation of global risk in HT subjects. PP is the main BP component in increasing CV risk in subjects with COPD. Controlled trials should be performed to evaluate the pressor targets to be reached in HT subjects with COPD, with the aim of decreasing their CV risk.

Abstract
Cardiovascular death represents the single largest cause of mortality in women with 70% of deaths attributable to modifiable risk factors, such as hypertension. This analysis aims at evaluating, whether there are gender disparities in antihypertensive drug usage and blood pressure (BP) control. We included 18 017 patients with arterial hypertension from the International Survey Evaluating Microalbuminuria Routinely by Cardiologists in patients with Hypertension (I-SEARCH). The study was conducted between September 2005 and March 2006 in 26 countries, and data on patient demographics, cardiovascular disease and risk factors, BP, and cardiovascular drug treatment were collected. Mean systolic blood pressure (SBP) was 2.1 mm Hg higher in women (150.6+/-0.35 mm Hg, n=8357/18 017) than in men (148.5+/-0.35 mm Hg; P<0.0001, n=9526/18 017), whereas no difference in diastolic BP was seen (88.2+/-0.20 vs 88+/-0.20 mm Hg; P=0.198). Gender differences in SBP were more pronounced in diabetic as compared with non-diabetic patients (3.5 vs 1.7 mm Hg, n=4272 vs n=13 611; P<0.0001) and became evident at an age 55 years old. Overall BP-control rate was 33.6% in men and 30.6% in women (P<0.0001) and was lower in diabetic as compared with non-diabetic patients. In all, 30% of patients used one, 40% used two and 30% used > or = 3 drugs without gender differences. Response rates to different drug regimens appeared to be similar. However, women received more frequently thiazides and beta-blockers, and less frequently ACE-inhibitors as monotherapy. Major efforts are required to improve BP-management, especially in women.

Abstract
High systolic blood pressure represents a challenge for the modern world. Epidemiologists are in the best position to appreciate the importance of systolic hypertension and its cardiovascular consequences. Although the label of hypertension seems to have lower importance in the elderly, and above all in the very old, than in younger people, high systolic and high pulse pressure are risk factors for cardiovascular events and necessitates treatment. Unfortunately, due to indolence and lack of aggressiveness, only a limited fraction of elderly hypertensive patients receives adequate therapy.

Abstract
Research suggests pulse pressure (PP) is a predictor of cardiovascular disease, and genes likely influence PP levels. Additionally, gender may be an effect modifier between PP and cardiovascular disease. This study addresses whether two renin-angiotensin-aldosterone system (RAAS) variants are associated with PP in a sex-specific manner (genotype-by-sex interaction). Subjects comprised 35,048 GenHAT study participants over 55 years old, approximately half were women and half non-Hispanic white. Blood pressure measurements were obtained 6 months after randomization to one of four antihypertensive medications. The polymorphisms considered were AGT-6 and ACE-I/D. We employed linear regression to assess the interaction. AGT-6 showed a significant (p < 0.001) genotype-by-sex interaction. Men with the 'G/G' genotype had a higher PP (0.6 mm HG) than men carrying an 'A' allele, while 'G/G' women had a lower PP (0.7 mm Hg) than women carrying an 'A' allele. Three of the four treatment groups (chlorthalidone, amlodipine and lisinopril) suggested a consistent interaction in sub-group analyses (only amlodipine was statistically significant, p < 0.001), whereas doxazosin did not. The interaction was evident among non-Hispanic participants but not among Hispanic participants. For ACE-I/D no evidence for a genotype-by-sex interaction was detected. This finding of genotype-by-sex interaction on PP helps our understanding of the complexity of genetic effects on blood pressure.

Abstract
The classification of arterial hypertension (HT) to define metabolic syndrome (MS) is unclear in that different cutoffs of blood pressure (BP) have been proposed. We evaluated the categorization of HT most qualified to define MS in relationship with coronary heart disease (CHD) mortality at a population level. A total of 3257 subjects aged > or =65 years were followed up for 12 years. MS was defined according to the criteria of the National Education Cholesterol Program using three different categories of HT: MS-1 (systolic blood pressure (SBP) > or =130 and diastolic blood pressure (DBP) > or =85 mm Hg), MS-2 (SBP > or =130 or DBP > or =85 mm Hg) and MS-3 (pulse pressure (PP) > or =75 mm Hg in men and > or =80 mm Hg in women). Gender-specific adjusted hazard ratio (HR) with 95% confidence intervals (CI) for CHD mortality was derived from Cox analysis in the three MS groups, both including and excluding antihypertensive treatment. In women with MS untreated for HT, the risk of CHD mortality was always significantly higher than in those without MS, independent of categorization; the HR of MS was 1.73 (CI 1.12-2.67) using MS-1, 1.75 (CI 1.10-2.83) using MS-2 and 2.39 (CI 3.71-1.31) using MS-3. In women with MS treated for HT, the HR of CHD mortality was significantly increased only in the MS-3 group (1.92, CI 1.1-2.88). MS did not predict CHD in men. In conclusion, MS can predict CHD mortality in elderly women with untreated HT but not in those with treated HT; in the latter, PP is the most predictive BP value.

Abstract
Evidence shows that an elevated pulse pressure (PP) may lead to an increased risk of cardiovascular morbidity and mortality. There is also evidence that PP is a sexually dimorphic trait, and that genetic factors influence inter-individual variation in PP. The aim of this project was to assess the genotype-by-sex interaction on PP in a sample of mostly hypertensive African American and White participants using candidate genes involved in the renin-angiotensin-aldosterone system. Subjects were participants in the HyperGEN Study, including men (43%) and women (57%) over the age of 55 years (mean age = 65). Candidate gene polymorphisms used were ACE insertion/deletion (1,789 subjects genotyped) and AGT-M235T (1,800 subjects genotyped). We employed linear regression methods to assess the genotype-by-sex interaction. For ACE, genotype-by-sex interaction on PP was detected (P = 0.04): the "D/D" genotype predicted a 2.2 mmHg higher pulse pressure among women, but a 1.2 mmHg lower PP among men, compared to those with an "I" allele, after adjusting for age, weight, height, ethnicity, and antihypertension medication use. A similar interaction was found for systolic blood pressure. The genotype-by-sex interaction was consistent across ethnicity. The interaction was evident among those on antihypertensive medications (P = 0.05), but not among those not taking such medications (P = 0.55). In our analysis of AGT, no evidence of a genotype-by-sex interaction affecting PP, SBP, or DBP was detected. This evidence for a genotype-by-sex interaction helps our understanding of the complex genetic underpinnings of blood pressure phenotypes.

Abstract
BACKGROUND AND OBJECTIVES Beyond a global estimation of the cardiovascular risk through the assessment of major risk factors and their integration in dedicated risk scales or equations, the use of specific markers provides additive prognostic information at an individual level, including predisposing factors, which are not included in the risk equations as well as the individual susceptibility to their long-term exposure. However, the majority of these markers require specific devices and skills, which are not widely available in primary care. METHODS Some clinical and/or "low-cost" parameters are shown to be valuable risk markers, and their use could refine the risk estimation in a physician's office. Several epidemiologic studies suggest the heart rate, the pulse pressure and the ankle-brachial index are effective cardiovascular risk markers. The arms systolic pressure asymmetry could also be a useful marker of risk. RESULTS AND CONCLUSIONS Through a general review, the authors evaluate the potential of these clinical markers, including their use in combination for more accurate risk determination.

Abstract
BACKGROUND AND PURPOSE Studies of blood pressure (BP) indices as disease predictors have offered conflicting conclusions. We compare pulse pressure (PP), systolic BP (SBP) and diastolic BP (DBP), and mean arterial pressure (MAP) as risk markers for long-term mortality with emphasis on stroke. METHODS Male civil servants (40 to 65 years of age; n=9611) were examined in 1963 and followed up until 1986. Multivariate analysis was used to assess the association between BP indices and subsequent mortality. Stroke mortality was analyzed separately for initially normotensive (SBP< or =140 and DBP< or =90 mm Hg), hypertensive (SBP>140 and DBP>90 mm Hg), and men with isolated systolic hypertension (ISH; SBP>140 and DBP< or =90 mm Hg). RESULTS During follow-up, 3167 men died, including 932 of coronary heart disease and 339 of stroke. All 4 BP indices were predictive of fatal stroke among hypertensive and normotensive men (hazard ratios [HRs] fluctuated between 1.59 and 2.51). In models with 2 BP indices among normotensive men, SBP but not DBP remained a predictor of stroke mortality. MAP and PP were independent predictors of stroke mortality. Among hypertensive men, SBP and DBP were independent predictors of stroke mortality (HRs, 1.68 and 1.51, respectively). MAP but not PP remained a predictor of stroke mortality. In men with ISH, the 4 BP indices predicted fatal stroke, with HRs fluctuating between 1.24 and 2.04. CONCLUSIONS All 4 BP indices were predictors of stroke mortality among hypertensive and normotensive men, with DBP possibly the weaker predictor among the latter. Models with 2 BP indices yielded complex associations.

Abstract
Epidemiology, genetic analysis and clinical studies are of help in understanding how, to what extent and why systolic blood pressure increases with age (at least in Western societies), while diastolic blood pressure increases only until the age of 60–65 years. Systolic blood pressure is a predictor of outcome in humans, but pulse pressure (systolic minus diastolic) is a better predictor, particularly in the elderly. Although the cardiovascular risk pattern is different in older patients, antihypertensive treatment remains useful in the elderly and even in the very old. Nevertheless, excessive reduction of diastolic blood pressure should be avoided in order to prevent increasing pulse pressure. Although all therapeutic regimens tend to reduce systolic more than diastolic blood pressure (reducing pulse pressure), the need for antihypertensive drugs acting selectively on systolic values remains very strong.

Abstract
Mortality and morbidity appear to be higher in a Cimbrian population representing an enclave of people who migrated from medieval Germany to the secluded Leogra valley in Italy. A population-based study was organized, recruiting 881 elderly subjects of Cimbrian origin and comparing them with a standard control population (SCP, n = 3,282) having comparable general characteristics and lifestyle. Serum lipids and glucose, blood pressure, heart rate, respiratory function, ECG abnormalities, and historical events were used as risk indicators. Age-adjusted systolic and pulse pressure were higher in the Cimbrians than in the SCP, while diastolic blood pressure was comparable. The prevalences of arterial hypertension, isolated systolic hypertension, and pulse hypertension were significantly more represented among Cimbrians than SCP. The prevalences of diabetes, hypercholesterolemia, and hypertriglyceridemia were higher among the former than the latter. The ratio between apolipoproteins B and A1 was also higher, while the HDL fraction was significantly lower in Cimbrians than in the SCP. In Cimbrians, the relative risk (RR) for ischemic heart disease was 1.92 (1.57-2.34) in women, 2.30 (1.54-3.43) in men and 1.03 (1.00-1.06) in women for stroke, 2.43 (1.54-3.83) in men and 1.45 (1.01-1.12) in women for atrial fibrillation, 3.85 (2.83-5.24) in men and 1.39 (1.20-1.60) in women for respiratory disease, 1.97 (1.32-2.94) in men and 6.81 (4.38-10.60) in women for intermittent claudication, and 3.31 (2.44-4.50) in men and 2.30 (1.76-3.01) in women for left ventricular hypertrophy. The subjects living in the secluded Leogra valley are at higher cardiovascular risk than the standard controls. Whether this depends on genetic factors, lifestyle, or both will need to be clarified by further analysis.
