Kaplan-Meier curve for stroke in AF Conclusions: Elevated hsTnT levels are significantly associated with higher risk of stroke in patients with AF, even after adjustment for various risk factors. Measurement of hsTnT and its inclusion in scores for stroke risk assessment should be considered in patients presenting to an emergency department with AF.

In 7 of the former and 5 of the latter the effect of atenolol (200 mg/day) was also investigated. Blood pressure variability as judged by circadian rhythm, standard deviation, coefficient of variation, indexes of skewness and kurtosis was similar in the two groups. The only significant difference consisted in the mean arterial pressure which was higher in the established than in the labile hypertensives. Atenolol produced in all subjects a fall in blood pressure but no significant changes in the standard deviation, coefficient of variation and index of skewness. On the contrary the index of kurtosis significantly increased suggesting a more stable blood pressure after treatment.

Blood pressure variability (BPV) may be increased in obese individuals and thus impair prognosis. The purpose of this study was to evaluate whether the relationship between obesity and mortality is influenced by short-term ambulatory BPV. The analysis was performed in 8724 participants (54% men) aged 51 ± 15 years enrolled in 8 prospective studies in Australia, Italy, Japan, and U.S.A. The predictive power of obesity (BMI >=30 kg/m2) for mortality was evaluated from multivariable Cox models in the subjects stratified by high or low nocturnal BPV (above or below the median). Obese participants (N = 1286) had higher age-and-sex adjusted systolic and diastolic BPV than the non-obese participants (p = 0.002/<0.001). Obese subjects with high systolic or diastolic BPV had higher nocturnal heart rate (p = 0.01/<0.001) than obese subjects with low BPV and were more frequently diabetic (p<0.001) and heavy alcohol drinkers (p < 0.001). During a median follow-up of 6.4 years there were 361 deaths, 4.7% in the obese and 4.0% in the non-obese individuals (P = NS). However, the risk of mortality among the obese subjects greatly differed according to BPV level. In Cox models including age, sex, mean ambulatory BP, smoking, alcohol use, diabetes, cholesterol, creatinine, and nocturnal heart rate, the obese group with high systolic BPV had a doubled risk of mortality compared to the non-obese group (HR,2.0, 95%CI,1.4-2.9, p < 0.001), whereas the risk was not increased in the obese group with low BPV (P = 0.81). Similar results were found for diastolic BPV, with a HR of 1.7 (1.2-2.5, p = 0.002) in the high BPV group and no association at all with mortality (p = 0.87) in the low BPV group. Inclusion of night-time BP dipping in the regressions did not change the strength of the associations. These data show that high nocturnal BPV greatly increases the risk of mortality related to obesity. High BPV is accompanied by increased heart rate and may reflect the influence of transient BP elevations related to sleep apnea and/or baroreflex dysfunction.

The skeletal muscle lesion is proven by the release of enzymes and other muscular components into the bloodstream and this is proportional to the amount and length of effort. The hypothesis that the heart muscle can be involved as well has not been unequivocally proven. The aim of this study, whose experimental model is that of a long-lasting endurance race in mountain, was to correlate hemodynamic variations with circulating and systemic modifications. Twenty-two well-trained endurance athletes (mean age 37.6 ± 8.4 years) performed a 30-km race at 869-2522 m. The day before and immediately after the race, each athlete underwent blood letting, echocardiogram, blood pressure measurement in triplicate, and leg and forearm strain-gauge plethysmography. Creatine kinase and its MB fraction, myoglobin and cardiac troponin I increased significantly after the run. Cardiac tropanin T also increased, not reaching statistical significance. Alkaline phosphatase increased but the alkaline/hematocrit ratio was unchanged. Lactate dehydrogenase and aspartate aminotransferase were increased after the race, while alanine aminotransferase and gamma glutamyltransferase did not change. Systolic and diastolic blood pressure decreased by 9.9% and 16.5%, respectively, while heart rate was 33% higher. No echocardiographic variation was found, so that cardiac output increase (+31.6%) entirely depended on heart rate increase. Leg resistance decreased after the race by 30%, together with a 49% increase in arterial flow. Forearm flow resistance trends paralleled those of leg. In the multiple regression adjusted for confounders, exercise-related leg flow increase directly correlated with creatine kinase increase. In conclusion, long-lasting endurance exercise in altitude produces a release of great amount of myocytolysis enzymes and a blood pressure reduction completely attributable to peripheral vasodilation.

Aim of this study was to investigate the association of white-coat tachycardia and masked tachycardia with MACE and mortality in hypertensive patients. Methods: We performed 24-h ambulatory blood pressure and HR monitoring in 7602 hypertensive patients (4165 men) aged 52 AE 16 years enrolled in six prospective studies in Italy, Japan, and Australia. Participants were divided into four groups: normal office and normal night-time HRs (N ¼ 5238), white-coat tachycardia (N ¼ 998), masked tachycardia (N ¼ 796), and sustained tachycardia (N ¼ 570). Median follow-up was 5.0 years. Results: In age-and-sex-adjusted Cox model, using the normal HRs group as a reference, white-coat tachycardia was not a significant predictor of excess MACEs or allcause death. In contrast, both masked tachycardia [hazard ratio, 95% confidence interval (CI); 1.40, 1.11-1.77] and sustained tachycardia (1.86, 1.44-2.40) were associated with risk of excess MACE. In addition, masked tachycardia (hazard ratio, 95% CI; 1.62, 1.14-2.29) but not sustained tachycardia (1.35, 0.83-2.19) was a significant predictor of excess mortality. These relationships held true in multivariable parsimonious Cox models including major risk factors. In these models, masked tachycardia remained an independent predictor of excess MACE (hazard ratio, 95% CI; 1.34, 1.06-1.71) and all-cause mortality (1.68, 1.18-2.41). Conclusion: The current study confirms that measurement of HR adds to the risk stratification for MACE and mortality and shows that an elevated night-time HR confers an increased mortality risk to hypertensive patients who have normal office HR.

We aimed to estimate the allometric exponents that best describe the relationships between cardiac dimensions and body size, propose normative values, and analyze how the different scaling metrics influence the prevalence of left ventricular hypertrophy (LVH) and chambers enlargement as well as predictive models for cardiovascular outcome in the community. We measured left ventricular end-diastolic dimension, end-diastolic volume, left ventricular mass, and left atrial volume in randomly recruited population cohorts (n = 1509; 52.8% women; mean age, 47.8 years). In a healthy subgroup (n = 656), the allometric exponents that described the relationships between left ventricular end-diastolic dimension and body size were 1, 0.5, and 0.33 for body height, body surface area (BSA), and estimated lean body mass, respectively. With regard to left ventricular end-diastolic volume, left ventricular mass, and left atrial volume the allometric exponents for body height were 2.9, 2.7, and 2.0, respectively; for BSA, they ranged from 1.7 to 1.8; for estimated lean body mass all exponents were around 1. These exponents were used to appropriately scale the cardiac dimensions to body size and derived sex-specific cut-off limits for different indexed cardiac dimensions. The hazard ratios of cardiovascular outcome were highest for LVH defined by left ventricular mass/height. Our study resulted in a proposal for thresholds for various indexed cardiac dimensions. Left ventricular mass indexed to height was sensitive in detection of LVH associated with obesity and slightly better predicted outcome.

Aim of the present paper is to ascertain whether this is plausible for splanchnic vessels too. In 5 healthy volunteers aged 27.4±4.0 years, cardiac output, upper limb blood flow, mesenteric diameter, flow and mean flow velocity, and portal vein diameter and flow velocity were measured by bioimpedence, ultrasonography and LASER-Doppler in usual conditions of consciousness (pre-hypnosis) and during hypnotic suggestion of body heat. Following hypnotic body heating, splanchnic vasodilation (+59% in mesenteric blood flow, p<0.01; +16% in diameter; mean flow velocity +43%) was observed, paralleling upper limb flow, while portal vein diameter decreased by 25% (p<0.001) and portal vein mean flow by 30% (p<0.001) probably to maintain a constant pressure in the hepatic district in the context of the so-called hepatic arterial buffer response. As a consequence of abdominal and peripheral vasodilation, 9% reflex rise in heart rate and 15% in stroke volume were observed, leading to increase of cardiac index in comparison to baseline (+16%). Following reflex hyperdynamic status, systolic blood pressure insignificantly tended to increase from 111.8±21.9 mmHg to 116.0±13.7 mmHg (+6%). Hypnotic heating is therefore associated to splanchnic arterial vasodilation, a condition that reminds of other physical hyperdynamic conditions. The mental image of body heating therefore produces real and measurable physical effects that can be detected with the tools of physiologists.

Randomization (1:1) to either eplerenone or irbesartan will be pursued taking into account age, gender, baseline offi ce systolic BP levels and renal function. At eight, sixteen and twenty-four weeks, ABPM will demonstrate BP control, and a stepped-care approach with the addition of amlodipine and indapamide will be followed in those uncontrolled during the two intermediate trial time frames. Renal function, electrolyte disorders, fatal and non-fatal cardiovascular events and adverse events will be also evaluated. A sample size of 336 patients (allowing 15% dropouts) will confer 80% power to detect a 4 mmHg ABPM averaged systolic BP difference. The primary endpoint is the 24-h systolic BP difference at 24 weeks. Secondary endpoints: 1) the change in offi ce BP at 24 weeks;2) the intermediate change in 24-h systolic BP;3) the change in left ventricular mass and microalbuminuria at 24 weeks; 4) discontinuations from treatment because of adverse events. Trial registration: Clinicaltrials.gov NCT03476616;EudraCT: 2018-004809-58. Results: Ethics approval has been obtained from the hospital ethic committee board and the Hellenic National Organization for Medicines. The study will initiate in May 2019.

The objective of this part of the SABPA study was to determine if renin levels in low and high renin participants could contribute to endothelial dysfunction. Methods: This part of the SABPA study consisted of 113 black urbanized Africans (men and women) from the same socioeconomic status (school teachers) from South Africa. The participants were stratified into low (<6.18 pg/ml) and high (!6.18 pg/ml) renin levels. Blood pressure and other variables were determined with known methods. Active renin levels were determined with a radio-immunometric assay (Renin III Generation, CIS bio-international, Cedex, France). The Von Willebrand Factor (vWF) was analysed with ELISA assay. (DAKO, SA). A calorimetric method were used for urine creatinine and a turbidimetric method for albumin measurement. Results: In single regression analysis, renin levels associated negatively with the Von Willebrand Factor (rZ-0.3756; pZ0.016) only in the low renin African men. With partial regression analysis after adjustment for age and BMI, the association remained. Renin levels also associated negatively (rZ-0.4846; pZ0.002) with systolic blood pressure only in low renin men. No associations could be encountered with markers of inflammation (IL-6; CRP and TNF-a) as well as stiffness. Conclusion: The results revealed that renin causing endothelial dysfunction in low renin African men and may lead to high blood pressure in later life.

We, therefore, investigated the heritability of left ventricular diastolic traits and the composite diastolic score in nuclear families recruited from the general population. Methods: In a random sample of 316 nuclear families (452 parents and 600 offspring, mean age, 58.5 and 33.3 years), we measured transmitral early and late diastolic velocities (E and A) by pulsed wave Doppler, and mitral annular velocities (e' and a') by tissue Doppler. Using principal component analysis, we summarized seven Doppler indexes-namely, E, A, e' and a' velocities, and their ratios-into a single diastolic score. To calculate the heritability of diastolic indexes, we used variance decomposition in nuclear families and offspring as implemented in SOLAR and SAS, and the regression slope of offspring on mid-parent residual values. Results: In variance decomposition analyses in nuclear families, the abovementioned traits with adjustment for covariables had moderate heritability ranging from 0.27 to 0.43 (P < 0.0001 for all). The parent-offspring concordances of all diastolic indexes were significant and ranged from 0.17 for A (P ¼ 0.009) to 0.42 for e' (P < 0.0001). In nuclear families and offspring, the heritability estimates of the composite diastolic score were 0.42 and 0.64, respectively (P < 0.0001). Conclusion: Our study demonstrated moderate heritability of various indexes reflecting left ventricular diastolic function in nuclear families. The observation highlights the necessity of further research into the genes that affect left ventricular diastolic function.

The present study was designed to collect information on the relationship between diuretic-related hyperuricemia and cardiovascular events. Methods: The URic acid Right for heArt Health (URRAH) study is a nationwide, multicentre, observational cohort study involving data on individuals recruited from all the Italy territory under the patronage of the Italian Society of Hypertension with an average follow-up period of 122.3 ± 66.9 months. Patients were classified into four groups according to the diuretic use (yes vs. no) and serum uric acid (SUA) levels (higher vs. lower than the median value of 4.8 mg/dl). All-cause death, cardiovascular deaths and first cardiovascular event were considered as outcomes. Results: Seventeen thousand, seven hundred and forty-seven individuals were included in the analys...

The fMRI pattern in brain cortex activation while receiving a painful stimulus was recorded both during nonhypnosis and during HFA. The scanning protocol included the acquisition of a T1-weighted structural scan, 4 functional scans, a T2-weighted axial scan, and a fluid attenuated inversion recovery (FLAIR) scan. Total imaging time, including localization and structural image acquisitions, was approximately 60 minutes. Without HFA, the subjects reported subjective presence of pain, and the cortex primary sensory areas S1, S2, and S3 were activated. During HFA, the subjects reported complete absence of subjective pain and S1, S2, and S3 were deactivated. The findings suggest that HFA may prevent painful stimuli from reaching the sensory brain cortex, possibly through a gate-control mechanism.

A wide heterogeneity was evident, with 53 different nationalities, subdivided in Eastern Europe (38.2%), Northern Africa (17.6%), Center and Southern Africa (12.9%), Latin America (12.8%), Indian subcontinent (9.6%), Far East (5.5%), Middle East (3.4%) macro-areas. Gender distribution and body mass index were comparable in the Italian and in the Migrant groups. Despite a 10-year age difference (50 ± 12 vs. 41 ± 15 years; p < 0.001), the overall prevalence of hypertension was similar in the two groups (44.7% in Italians vs. 43.4% in Migrants), as defi ned by BP>140/90 mmHg and/ or current antyhypertensive treatment. When stratifi ed by age, Migrants presented signifi cantly higher BP values, the prevalence of hypertension being at least 10% higher than in Italian residents in any decade group. A similar trend was observed for awareness, active treatment and satisfactory BP control rates. Also the rate of proteinuria and glycosuria was higher in the spot urine sample analysis. Conclusions: In Migrants, hypertension prevalence, treatment rate and control rate are signifi cantly higher than in the Italian resident population. In the future years this will inevitably increase the burden of cardiovascular disease on society and health system. These data underscore the urgent need of prevention and intervention in this special population, trying to take into proper account all the involved social, cultural, economic and health-related factors.

By utilizing a large population-based database, we assessed the threshold of SUA that increases the risk of total mortality and cardiovascular mortality (CVM). The URRAH study (Uric Acid Right for Heart Health) is a multicentre retrospective, observational study, which collected data from several large population-based longitudinal studies in Italy and subjects recruited in the hypertension clinics of the Italian Society of Hypertension. Total mortality was defined as mortality for any cause, CVM as death due to fatal myocardial infarction, stroke, sudden cardiac death, or heart failure. A total of 22 714 subjects were included in the analysis. Multivariate Cox regression analyses identified an independent association between SUA and total mortality (hazard ratio, 1.53 [95% CI, 1.21–1.93]) or CVM (hazard ratio, 2.08 [95% CI, 1.146–2.97]; P <0.001). Cutoff values of SUA...

At baseline, daytime ambulatory (n=12 624) or home (n=5297) blood pressure were measured in 17 921 participants (51.3% women; mean age, 54.2 years) from 17 population cohorts. Subsequently, mortality and cardiovascular events were recorded. Using multivariable Cox regression, floating absolute risk was computed across 4 age bands (≤60, 61–70, 71–80, and >80 years). Over 236 491 person-years, 3855 people died and 2942 cardiovascular events occurred. From levels as low as 110/65 mm Hg, risk log-linearly increased with higher out-of-office systolic/diastolic blood pressure. From the youngest to the oldest age group, rates expressed per 1000 person-years increased (P<0.001) from 4.4 (95% CI, 4.0–4.7) to 86.3 (76.1–96.5) for all-cause mortality and from 4.1 (3.9–4.6) to 59.8 (51.0–68.7) for ca...

The general belief is that hypnosis is conscious and voluntary, but the practical demonstration of this hypothesis is far to be demonstrated. Twenty healthy highly hypnotizable volunteers were studied during through functional magnetic resonance imaging during a task. The task was necessary because functional magnetic resonance imaging gives no interesting results in neutral hypnosis. During the hypnotic task, the prefrontal dorso-lateral cortex, genual cortex, dorsal anterior cingulate cortex, and orbital portion of the inferior frontal convolution (i.e. the Broadmann areas 9, 25, 32 and 47) were activated. Such areas are associated to egoic consciousness and voluntary processes. The results show that the hypothesis that hypnosis is conscious and voluntary is correct.

Here, we report the derivation, validation, and illustration of the revised WHO cardiovascular disease risk prediction charts that have been adapted to the circumstances of 21 global regions. Methods In this model revision initiative, we derived 10-year risk prediction models for fatal and non-fatal cardiovascular disease (ie, myocardial infarction and stroke) using individual participant data from the Emerging Risk Factors Collaboration. Models included information on age, smoking status, systolic blood pressure, history of diabetes, and total cholesterol. For derivation, we included participants aged 40-80 years without a known baseline history of cardiovascular disease, who were followed up until the first myocardial infarction, fatal coronary heart disease, or stroke event. We recalibrated models using age-specific and sex-specific incidences and risk factor values available from 21 global regions. For external validation, we analysed individual participant data from studies distinct from those used in model derivation. We illustrated models by analysing data on a further 123 743 individuals from surveys in 79 countries collected with the WHO STEPwise Approach to Surveillance. Findings Our risk model derivation involved 376 177 individuals from 85 cohorts, and 19 333 incident cardiovascular events recorded during 10 years of follow-up. The derived risk prediction models discriminated well in external validation cohorts (19 cohorts, 1 096 061 individuals, 25 950 cardiovascular disease events), with Harrell's C indices ranging from 0•685 (95% CI 0•629-0•741) to 0•833 (0•783-0•882). For a given risk factor profile, we found substantial variation across global regions in the estimated 10-year predicted risk. For example, estimated cardiovascular disease risk for a 60-year-old male smoker without diabetes and with systolic blood pressure of 140 mm Hg and total cholesterol of 5 mmol/L ranged from 11% in Andean Latin America to 30% in central Asia. When applied to data from 79 countries (mostly low-income and middle-income countries), the proportion of individuals aged 40-64 years estimated to be at greater than 20% risk ranged from less than 1% in Uganda to more than 16% in Egypt. Interpretation We have derived, calibrated, and validated new WHO risk prediction models to estimate cardiovascular disease risk in 21 Global Burden of Disease regions. The widespread use of these models could enhance the accuracy, practicability, and sustainability of efforts to reduce the burden of cardiovascular disease worldwide.
