Habitual Regular Coffee Consumption And Arterial Stiffness -Data From The 3rd Pamela Survey.

BACKGROUND: We evaluated whether chronic coffee consumption affects arterial stiffness, assessed by cardio-ankle vascular index (CAVI). METHODS: In 514 subjects, aged 66.6±9.9 yrs (mean±SD), recruited in the 3rd follow-up of the PAMELA study, subdivided in 3 groups according to daily intake of regular coffee (0, 1-2 and ≥3 cups/day), we measured CAVI and clinic, ambulatory blood pressure (BP) and other variables. RESULTS: The 3 groups displayed similar age, gender, metabolic and renal pofile. Clinic and ambulatory BPs were similar in the 3 groups, this being the case for CAVI (0 cup: 9.1±1.8, 1-2 cups: 9.5±2.3 and ≥3 cups: 9.2±2.1 m/sec, P=NS). No significant gender-difference in CAVI and in participants under antihypertensive treatment was detected. CONCLUSIONS: our data show that chronic coffee consumption leaves unaffected arterial stiffness in the general population, this being the case in subgroups. The neutral vascular impact of coffee may favor the absence of any significant BP effect of habitual coffee intake.

Screening and management of hypertensive patients with chronic kidney disease referred to Hypertension Excellence Centres among 27 countries. A pilot survey based on questionnaire.

OBJECTIVE: Real-life management of hypertensive patients with chronic kidney disease (CKD) is unclear. METHODS: A survey was conducted in 2023 by the European Society of Hypertension (ESH) to assess management of CKD patients referred to ESH-Hypertension Excellence Centres (ESH-ECs) at first referral visit. The questionnaire contained 64 questions with which ESH-ECs representatives were asked to estimate preexisting CKD management quality. RESULTS: Overall, 88 ESH-ECs from 27 countries participated (fully completed surveys: 66/88 [75.0%]). ESH-ECs reported that 28% (median, interquartile range: 15-50%) had preexisting CKD, with 10% of them (5-30%) previously referred to a nephrologist, while 30% (15-40%) had resistant hypertension. The reported rate of previous recent (<6 months) estimated glomerular filtration rate (eGFR) and urine albumin-creatinine ratio (UACR) testing were 80% (50-95%) and 30% (15-50%), respectively. The reported use of renin-angiotensin system blockers was 80% (70-90%). When a nephrologist was part of the ESH-EC teams the reported rates SGLT2 inhibitors (27.5% [20-40%] vs. 15% [10-25], P = 0.003), GLP1-RA (10% [10-20%] vs. 5% [5-10%], P = 0.003) and mineralocorticoid receptor antagonists (20% [10-30%] vs. 15% [10-20%], P = 0.05) use were greater as compared to ESH-ECs without nephrologist participation. The rate of reported resistant hypertension, recent eGFR and UACR results and management of CKD patients prior to referral varied widely across countries. CONCLUSIONS: Our estimation indicates deficits regarding CKD screening, use of nephroprotective drugs and referral to nephrologists before referral to ESH-ECs but results varied widely across countries. This information can be used to build specific programs to improve care in hypertensives with CKD.

Effects of acute carotid baroreceptor stimulation on sympathetic nerve traffic in resistant and uncontrolled hypertension: a systematic review and meta-analysis.

In resistant hypertensive patients acute carotid baroreflex stimulation is associated with a blood pressure (BP) reduction, believed to be mediated by a central sympathoinhbition.The evidence for this sympathomodulatory effect is limited, however. This meta-analysis is the first to examine the sympathomodulatory effects of acute carotid baroreflex stimulation in drug-resistant and uncontrolled hypertension, based on the results of microneurographic studies. The analysis included 3 studies assessing muscle sympathetic nerve activity (MSNA) and examining 41 resistant uncontrolled hypertensives. The evaluation included assessment of the relationships between MSNA and clinic heart rate and BP changes associated with the procedure. Carotid baroreflex stimulation induced an acute reduction in clinic systolic and diastolic BP which achieved statistical significance for the former variable only [systolic BP: -19.98 mmHg (90% CI, -30.52, -9.43), P < 0.002], [diastolic BP: -5.49 mmHg (90% CI, -11.38, 0.39), P = NS]. These BP changes were accompanied by a significant MSNA reduction [-4.28 bursts/min (90% CI, -8.62, 0.06), P < 0.07], and by a significant heart rate decrease [-3.65 beats/min (90% CI, -5.49, -1.81), P < 0.001]. No significant relationship was detected beween the MSNA, systolic and diastolic BP changes induced by the procedure, this being the case also for heart rate. Our data show that the acute BP lowering responses to carotid baroreflex stimulation, although associated with a significant MSNA reduction, are not quantitatively related to the sympathomoderating effects of the procedure. This may suggest that these BP effects depend only in part on central sympathoinhibition, at least in the acute phase following the intervention.

Left ventricular systolic dysfunction in obesity: a meta-analysis of speckle tracking echocardiographic studies.

BACKGROUND: Obesity is a risk factor for left ventricular hypertrophy (LVH) and diastolic dysfunction. Available evidence on impaired myocardial deformation in obese patients without apparent systolic dysfunction assessed by LV ejection fraction (LVEF) is based on single studies. The aim of the present meta-analysis was to provide a comprehensive and updated information on this issue. METHODS: The PubMed, OVID-MEDLINE, and Cochrane library databases were analysed to search English-language articles published from the inception up to 31 December 2023. Studies were identified by using MeSH terms and crossing the following search items: 'myocardial strain', 'left ventricular mechanics', 'longitudinal global strain', 'speckle tracking echocardiography', 'systolic dysfunction', 'left ventricular ejection fraction', and 'obesity'. RESULTS: Twenty-four studies including 5792 obese and 5518 nonobese individuals from different clinical settings were considered for the analysis. LV global longitudinal strain (GLS) was significantly impaired in the obese group [standard means difference (SMD): -0.86 ±â€Š0.08; confidence interval (CI) -1.02 to -0.69, P < 0.0001] and this was paralleled by a significant difference in pooled LVEF between obese and controls (SMD -0.27 ±â€Š0.06; CI -0.40 to -0.15, P < 0.0001). Unlike GLS, however, the majority of the selected studies failed to show statistically significant differences in LVEF. Furthermore, in patients with advanced obesity (BMI > 35 kg/m2, data from six studies), LV systolic dysfunction was more significantly detected by GLS (SMD -1.24 ±â€Š0.19, CI -1.61/-0.87, P < 0.0001) than by LVEF (SMD -0.54 ±â€Š0.27, CI -1.07 to -0.01, P = 0.046). CONCLUSION: The present meta-analysis suggests that GLS may unmask systolic dysfunction often undetected by conventional LVEF in the obese setting; thus, this parameter should be incorporated into routine work-up aimed to identify obesity-mediated subclinical cardiac damage.

Thirty-five years of the European Society of Hypertension: from past to future.

The European Society of Hypertension (ESH) was established 35 years ago. Since then, it promoted and coordinated a number of activities which include educational projects, epidemiological surveys and research investigations whose main focus includes different clinical and therapeutic aspects of the hypertensive disease. This article, which is based on data presented during the Presidential lecture held during the 33rd ESH Meeting in Berlin, will provide an overview of the main organization and structure of the ESH. Emphasis will be given to the relevance of the different society bodies, with a particular focus on the educational and research activities, such as the 15 working groups and the more than 120 excellence centers located in European and extra-European countries. Other main activities of the Society refer to the ESH Hypertension Specialist Program, the ESH Summer School, the ESH Young Fellow Program and the Annual Scientific Meeting of the Society. A special emphasis will be given to the central role of the Society in the organization of the various research projects and in the development and dissemination of the ESH Guideline document on hypertension diagnosis and treatment. Finally, the future perspectives of the ESH in the context of the European scientific framework will be highlighted.

Prevalence, Clustering, and Current Management of Cardiovascular Risk Factors Upon First Referral to Hypertension Specialists: the APPROACH Study.

INTRODUCTION: Several observational studies have been conducted to assess the prevalence of cardiovascular risk factors in hypertensive patients; however, none has yet investigated prevalence, clustering, and current management of cardiovascular risk factors upon first referral to hypertension specialists, which is the aim of the present study. METHODS: Consecutive adult outpatients with essential/secondary hypertension were included at the time of their first referral to hypertension specialists at 13 Italian centers in the period April 2022-2023 if they had at least one additional major cardiovascular risk factor among LDL-hypercholesterolemia, type 2 diabetes, and cigarette smoking. Prevalence, degree of control, and current management strategies of cardiovascular risk factors were assessed. RESULTS: A total of 255 individuals were included, 40.2% women and 98.4% Caucasian. Mean age was 60.3±13.3 years and mean blood pressure [BP] was 140.3±17.9/84.8±12.3 mmHg). Most participants were smokers (55.3%), had a sedentary lifestyle (75.7%), suffered from overweight/obesity (51%) or high LDL-cholesterol (41.6%), had never adopted strategies to lose weight (55.7%), and were not on a low-salt diet (57.4%). Only a minority of patients reported receiving specialist counseling, and 27.9% had never received recommendations to correct unhealthy lifestyle habits. Nearly 90% of individuals with an estimated high/very high cardiovascular risk profile did not achieve recommended LDL-cholesterol targets. CONCLUSIONS: In patients with hypertension, both pharmacological and lifestyle therapeutic advice are yet to improve before referral to hypertension specialists. This should be considered in the primary care setting in order to optimize cardiovascular risk management strategies.

Impact of seasonal blood pressure changes on visit-to-visit blood pressure variability and related cardiovascular outcomes.

BACKGROUND: Visit-to-visit blood pressure (BP) variability associates with an increased risk of cardiovascular events. We investigated the role of seasonal BP modifications on the magnitude of BP variability and its impact on cardiovascular risk. METHODS: In 25 390 patients included in the ONTARGET and TRANSCEND trials, the on-treatment systolic (S) BP values obtained by five visits during the first two years of the trials were grouped according to the month in which they were obtained. SBP differences between winter and summer months were calculated for BP variability quintiles (Qs), as quantified by the coefficient of variation (CV) of on-treatment mean SBP from the five visits. The relationship of BP variability with the risk of cardiovascular events and mortality was assessed by the Cox regression model. RESULTS: SBP was approximately 4 mmHg lower in summer than in winter regardless of confounders. Winter/summer SBP differences contributed significantly to each SBP-CV quintile. Increase of SBP-CV from Q1 to Q5 was associated with a progressive increase in the adjusted hazard ratio (HR) of the primary endpoint of the trials, i.e. morbid and fatal cardiovascular events. This association was even stronger after removal of the effect of seasonality from the calculation of SBP-CV. A similar trend was observed for secondary endpoints. CONCLUSIONS: Winter/summer SBP differences significantly contribute to visit-to-visit BP variability. However, this contribution does not participate in the adverse prognostic significance of visit-to-visit BP variations, which seems to be more evident after removal of the BP effects of seasonality from visit-to-visit BP variations.

Sympathetic overactivity, hypertension and cardiovascular disease: state of the art.

Cardiovascular disease (CVD) remains the most prevalent cause of premature death worldwide. It had been suspected for decades that increased activity of the sympathetic nervous system (SNS) might play a pathogenetic role in the development and progression of hypertension, heart failure (HF) and CVD. The use of microneurographic techniques to directly assess the SNS has allowed this field to advance considerably in recent years. We now have compelling evidence for a key role of sympathetic overactivity in the pathogenesis and progression of hypertension and associated hypertension-mediated organ damage (such as endothelial dysfunction, arterial stiffness and left ventricular hypertrophy), HF (with or without reduced left ventricular ejection fraction). Sympathetic overactivity also drives increased cardiovascular risk in the settings of obesity, metabolic syndrome, chronic kidney disease and obstructive sleep apnoea, among other conditions. Thus, sympathetic overactivity is an important factor that drives patients through the CVD continuum, from the early appearance of cardiovascular risk factors, to impairments of the structure and function of components of the heart and arteries, to established CVD, and ultimately to a life-threatening cardiovascular event. A deeper understanding of the role of sympathetic overactivity in the pathogenesis of CVD and HF will support the optimization of therapeutic interventions for these conditions.

Habitual coffee consumption and office, home, and ambulatory blood pressure: results of a 10-year prospective study.

OBJECTIVES: Heterogeneous are the results of the published studies aimed at determining the long-term effects of habitual coffee consumption on blood pressure (BP). Specifically, no data are available on the longitudinal association between habitual coffee consumption and office, home and 24 h BP profile and variability. METHODS: In 1408 subjects recruited in the Pressioni Arteriose Monitorate E Loro Associazioni (PAMELA) study, followed for a 10 year follow-up period and classified as coffee consumers and nonconsumers (self-reporting), we prospectically investigated the association between habitual coffee consumption and office, home and 24-h ambulatory BP; 24-h BP variability; and development of a new hypertensive state. Data were also analysed according to gender. RESULTS: When data were adjusted for confounders habitual coffee nonconsumers and consumers displayed similar long-term BP changes during the follow-up in office, home, and ambulatory BP. No difference was found between heavy and moderate coffee consumers. Furthermore, also new-onset hypertension and patterns of BP variability were superimposable in coffee nonconsumers and consumers, independently on confounders including gender, number, and characteristics of the antihypertensive drug treatment. CONCLUSION: The present study, which is the first longitudinal investigation never performed examining in a prospective fashion the long-term (10 year) effects of coffee consumption on office, home, and ambulatory BP, provides conclusive evidence that habitual coffee consumption is associated with neutral effects on in-office and out-of-office BP values and related variabilities. This is the also the case for the new-onset hypertensive state.

Assessment and management of exaggerated blood pressure response to standing and orthostatic hypertension: consensus statement by the European Society of Hypertension Working Group on Blood Pressure Monitoring and Cardiovascular Variability.

Recent evidence suggests that an exaggerated blood pressure (BP) response to standing (ERTS) is associated with an increased risk of adverse outcomes, both in young and old individuals. In addition, ERTS has been shown to be an independent predictor of masked hypertension. In the vast majority of studies reporting on the prognostic value of orthostatic hypertension (OHT), the definition was based only on systolic office BP measurements. This consensus statement provides recommendations on the assessment and management of individuals with ERTS and/or OHT. ERTS is defined as an orthostatic increase in SBP at least 20 mmHg and OHT as an ERTS with standing SBP at least 140 mmHg. This statement recommends a standardized methodology to assess ERTS, by considering body and arm position, and the number and timing of BP measurements. ERTS/OHT should be confirmed in a second visit, to account for its limited reproducibility. The second assessment should evaluate BP changes from the supine to the standing posture. Ambulatory BP monitoring is recommended in most individuals with ERTS/OHT, especially if they have high-normal seated office BP. Implementation of lifestyle changes and close follow-up are recommended in individuals with ERTS/OHT and normotensive seated office BP. Whether antihypertensive treatment should be administered in the latter is unknown. Hypertensive patients with ERTS/OHT should be managed as any other hypertensive patient. Standardized standing BP measurement should be implemented in future epidemiological and interventional studies.

Serum Uric Acid/Serum Creatinine Ratio and Cardiovascular Mortality in Diabetic Individuals-The Uric Acid Right for Heart Health (URRAH) Project.

Several studies have detected a direct association between serum uric acid (SUA) and cardiovascular (CV) risk. In consideration that SUA largely depends on kidney function, some studies explored the role of the serum creatinine (sCr)-normalized SUA (SUA/sCr) ratio in different settings. Previously, the URRAH (URic acid Right for heArt Health) Study has identified a cut-off value of this index to predict CV mortality at 5.35 Units. Therefore, given that no SUA/sCr ratio threshold for CV risk has been identified for patients with diabetes, we aimed to assess the relationship between this index and CV mortality and to validate this threshold in the URRAH subpopulation with diabetes; the URRAH participants with diabetes were studied (n = 2230). The risk of CV mortality was evaluated by the Kaplan-Meier estimator and Cox multivariate analysis. During a median follow-up of 9.2 years, 380 CV deaths occurred. A non-linear inverse association between baseline SUA/sCr ratio and risk of CV mortality was detected. In the whole sample, SUA/sCr ratio > 5.35 Units was not a significant predictor of CV mortality in diabetic patients. However, after stratification by kidney function, values > 5.35 Units were associated with a significantly higher mortality rate only in normal kidney function, while, in participants with overt kidney dysfunction, values of SUA/sCr ratio > 7.50 Units were associated with higher CV mortality. The SUA/sCr ratio threshold, previously proposed by the URRAH Study Group, is predictive of an increased risk of CV mortality in people with diabetes and preserved kidney function. While, in consideration of the strong association among kidney function, SUA, and CV mortality, a different cut-point was detected for diabetics with impaired kidney function. These data highlight the different predictive roles of SUA (and its interaction with kidney function) in CV risk, pointing out the difference in metabolic- and kidney-dependent SUA levels also in diabetic individuals.

Italian Society of Interventional Cardiology (GISE) and Italian Society of Arterial Hypertension (SIIA) Position Paper on the role of renal denervation in the management of the difficult-to-treat hypertension.

Renal denervation (RDN) is a safe and effective strategy for the treatment of difficult to treat hypertension. The blood pressure (BP)-lowering efficacy of RDN is comparable to those of many single antihypertensive medications and it allows to consider the RDN as a valuable option for the treatment of difficult to treat hypertension together with lifestyle modifications and medical therapy. A multidisciplinary team is of pivotal importance from the selection of the patient candidate for the procedure to the post-procedural management. Further studies are needed to investigate the effect of RDN on clinical outcomes and to better identify the predictors of BP response to RDN in order to recognize the patients who are more likely to benefit from the procedure.

Association Between Elevated Body Mass Index and Cardiac Organ Damage in Children and Adolescents: Evidence and Mechanisms.

INTRODUCTION: Although a number of pathophysiological aspects of childhood obesity have been reported, few information are available on obesity-related cardiac organ damage. AIM: The present study was aimed at assessing the impact of anthropometric, blood pressure (BP) and metabolic variable on cardiac structure and function in youth. METHODS: In 78 subjects aged 5-16 years attending the outpatient clinic of cardiovascular risk (Valencia, Spain) anthropometric and metabolic variables, clinic and ambulatory BP and echocardiographic parameters were assessed. Subjects were also classified according to the presence of insulin resistance. RESULTS: Subjects mean age (± SD) amounted to 12.03 ± 2.4 years and males to 53.8%. Ten subjects were normoweight, 11 overweight, 39 obese, and 18 severely obese. No significant difference in office and ambulatory BP was detected among different bodyweight groups. A significant direct correlation was observed between left ventricular mass index (LVMI) and obesity markers [body mass index (BMI): r = 0.38, waist circumference (WC): r = 0.46, P < 0.04 for both]. Left ventricular hypertrophy, relative wall thickness and left atrial diameter were significantly related to BMI and WC. In contrast, office and ambulatory BP were unrelated to other variables, and differences in LVMI among different BP phenotypes were not significant. When partitioning the population by insulin resistance, LVMI, adjusted for confounders, was significantly greater in the insulin-resistant group. CONCLUSIONS: In children and adolescents characterized by different body weight patterns, weight factors "per se" and the related insulin resistance state appear to represent the main determinants of LVMI and left ventricular hypertrophy, independently on BP values and BP phenotypes.
