Management of Renovascular Hypertension and Renal Denervation in Patients with Hypertension: An Italian Nationwide Survey.

INTRODUCTION: Renovascular hypertension (RVH) remains underdiagnosed despite its significant cardiovascular and renal morbidity. AIM: This survey investigated screening and management practices for RVH among hypertensive patients in Italian hypertension centres in a real-life setting. Secondary, we analysed the current spread of renal denervation (RDN) and the criteria used for its eligibility. METHODS: A 12 item-questionnaire was sent to hypertension centres belonging to the European Society of Hypertension and to the Italian Society of Hypertension (SIIA) in Italy. Data concerning the screening and management of RVH and of RDN were analysed according to the type of centre (excellence vs non-excellence centres), geographical area and medical specialty. RESULTS: Eighty-two centres participated to the survey. The number of patients diagnosed in each centre with RVH and fibromuscular dysplasia during the last five years was 3 [1;6] and 1 [0;2], respectively. Despite higher rates of RVH diagnosis in excellence centres (p = 0.017), overall numbers remained unacceptably low, when compared to expected prevalence estimates. Screening rates were inadequate, particularly among young hypertensive patients, with only 28% of the centres screening for RVH in such population. Renal duplex ultrasound was underused, with computed tomographic angiography or magnetic resonance angiography reserved for confirming a RVH diagnosis (76.8%) rather than for screening (1.9-32.7%, according to patients' characteristics). Scepticism and logistical challenges limited RDN widespread adoption. CONCLUSIONS: These findings underscore the need for improving RVH screening strategies and for a wider use of related diagnostic tools. Enhanced awareness and adherence to guidelines are crucial to identifying renovascular hypertension and mitigating associated cardiovascular and renal risks.

Gene editing of angiotensin for blood pressure management.

Arterial hypertension has remained the world's leading cause of morbidity and mortality for more than 20 years. While early Genome-Wide Association Studies raised the hypothesis that a precision medicine approach could be implemented in the treatment of hypertension, the large number of single nucleotide polymorphisms that were found to be associated with blood pressure and their limited impact on the blood pressure values have initially hampered these expectations. With the development and refinement of gene-editing and RNA-based approaches allowing selective and organ-specific modulation of critical systems involved in blood pressure regulation, a renewed interest in genetic treatments for hypertension has emerged. The CRISPR-Cas9 system, antisense oligonucleotides (ASO) and small interfering RNA (siRNA) have been used to specifically target the hepatic angiotensinogen (AGT) production, with the scope of safely but effectively reducing the activation of the renin-angiotensin system, ultimately leading to an effective reduction of the blood pressure with extremely simplified treatment regimens that involve weekly, monthly or even once-in-life injection of the drugs. Among the various approaches, siRNA and ASO that reduce hepatic AGT production are in advanced development, with phase I and II clinical trials showing their safety and effectiveness. In the current manuscript, we review the mode of action of these new approaches to hypertension treatment, discussing the results of the clinical trials and their potential to revolutionize the management of hypertension.

Healthy Eating beyond Whole Grains-Insight on Associations between Diet Quality and Arterial Stiffness in the Brisighella Heart Study Cohort.

Although whole grains have well-recognized protective effects against the development of cardiometabolic diseases, whole grain foods are poorly consumed by the general population. The aim of our study was to establish, at a population level, the vascular impact of a low intake of whole grain foods. From the initial cohort of the Brisighella Heart Study, we identified a population sample of 1503 individuals-including 720 men (47.9%) and 783 women (52.1%)-who overall largely consumed refined grain products. Diet quality was estimated by the Short Healthy Eating Index (sHEI), and women were found to have an eating pattern that was overall healthier than men (44.1 ± 8.5 vs. 36.3 ± 8.1, p < 0.001). The development of an age- and blood pressure (BP)-adjusted multiple linear regression model found that carotid-femoral pulse wave velocity (cfPWV) was significantly predicted by the estimated glomerular filtration rate (eGFR, B = -0.148, 95% Confidence Interval (CI) -0.259--0.038, p < 0.001), serum uric acid (SUA, B = 0.220, 95%CI 0.095-0.320, p = 0.001) and sHEI (B = -0.231, 95%CI -327--0.089, p < 0.001) in men, and by eGFR (B = -0.152, 95%CI -0.266--0.052, p < 0.001), body mass index (BMI, B = 0.174, 95%CI 0.111-0.331, p = 0.002), SUA (B = 0.278, 95%CI 0.158-0.354, p < 0.001) and sHEI (B = -0.218, 95%CI -308--0.115, p < 0.001) in women. Ultimately, a low sHEI score was a significant predictor of arterial stiffness also in a population cohort with a high consumption of refined grain products.

Effectiveness of high-dose esomeprazole or pantoprazole 10-day sequential therapy empirically prescribed in Helicobacter pylori-infected naïve patients: a retrospective study.

BACKGROUND AND AIM: Helicobacter pylori infection is one of the most common bacterial infections affecting humans, causing gastroduodenal and extraintestinal diseases. Treatment of the infection remains challenging for the clinicians, and different factors are involved in the failure of the therapeutic approach. The importance of the intensity of acid secretion inhibition remains an unclear issue. The aim of this study is to assess whether 80 mg/day esomeprazole-based 10-day sequential therapy (esomeprazole-ST) achieved different eradication rates when compared to 80 mg/day pantoprazole-based analogous regimen (pantoprazole-ST). METHODS: This was a retrospective observational study where data of consecutive patients referred by their physicians to our unit to perform an upper gastrointestinal endoscopy were analyzed. RESULTS: Overall, 1,327 patients were available for the analysis: 599 and 728 patients received pantoprazole-ST and esomeprazole-ST, respectively. Eradication rate was significantly higher in patients receiving esomeprazole-ST (92.6%, 95% CI: 91-94.5) than pantoprazole-ST (89.3%, 95% CI: 86.7-91.7; difference: 3.3%; 95% CI: 0.2-6.5; P = 0.037). Even after a multivariate analysis, the esomeprazole-ST achieved a significantly higher eradiation (OR: 1.44; 95% CI: 1.1-2.17). CONCLUSIONS: This study showed that esomeprazole-ST achieved significantly higher H. pylori cure rates than pantoprazole-ST. Prospective and well-designed trials are demander to confirm this prelaminar finding.

Effect of Supplementation of a Butyrate-Based Formula in Individuals with Liver Steatosis and Metabolic Syndrome: A Randomized Double-Blind Placebo-Controlled Clinical Trial.

Postbiotics could exert different metabolic activities in animal models of non-alcoholic fatty liver disease (NAFLD) and in humans affected by metabolic syndrome. This is a randomized, double-blind, placebo-controlled, parallel-group clinical trial that enrolled a sample of 50 Caucasian healthy individuals with NAFLD, defined as liver steatosis, and metabolic syndrome. After a 4-week run-in, the enrolled individuals were randomized to take a food for special medical purposes with functional release, one tablet a day, containing calcium butyrate (500 mg/tablet), zinc gluconate (zinc 5 mg/tablet), and vitamin D3 (500 IU/tablet), or an identical placebo for 3 months. Liver and metabolic parameters were measured at baseline and at the end of the study. No subject experienced any adverse events during the trial. In both groups, a significant decrease in total cholesterol (TC) and triglycerides (TG) plasma levels was observed at the randomization visit vs. pre-run-in visit (p < 0.05). Regarding liver parameters, after treatment, the fatty liver index (FLI) improved significantly vs. baseline values (p < 0.05) and vs. placebo group (p < 0.05) in the active treatment group, and the hepatic steatosis index (HSI) improved significantly vs. baseline values (p < 0.05). Moreover, after active treatment, TC, TG, and gamma-glutamyl transferase (gGT) improved significantly vs. baseline values (p < 0.05), and TC and TG improved vs. placebo group (p < 0.05), as well. In the placebo group, liver parameters remained unchanged after treatment; only TG improved significantly vs. baseline values (p < 0.05). In our study, we observed that the butyrate-based formula improved FLI and plasma lipid patterns in individuals affected by liver steatosis and metabolic syndrome.

East meets West: Bringing the ESH 2023 hypertension guidelines into Asia.

Hypertension remains a major problem worldwide, especially across the Asia-Pacific region, which reports high prevalence rates and slow improvements in treatment rate and blood pressure (BP) control rate. Asian patients with hypertension may also vary with regard to phenotype and the epidemiology of the complications of hypertension, especially when compared with Western patients. Given these differences, Western guidelines may not necessarily be applicable to countries in the Asia Pacific. This narrative review aims to provide a critical comparison between the recently published European Society of Hypertension (ESH) 2023 guidelines and existing local guidelines in select Asian countries, offer expert opinion on how to fill gaps in the ESH 2023 guidelines for hypertension in the Asian context, and examine the need for harmonisation of hypertension guidelines worldwide. This review focuses on the definition and diagnosis of hypertension, the treatment thresholds and targets, and recommendations on the use of pharmacotherapy.

Gender-Specific Medicine in the European Society of Cardiology Guidelines from 2018 to 2023: Where Are We Going?

Background/Objectives: Evidence-based medicine (EBM) shapes most clinical guidelines. Although the advent of EBM marked a significant advancement, failure to include sex differences in the study design and analysis of most trials leads to an under-representation of gender-specific medicine (GM) in EBM-directed guidelines. In this review, we evaluated how the topic of GM was developed in the guidelines produced by the European Society of Cardiology (ESC) from 2018 to 2023. Methods: Two independent reviewers evaluated 24 ESC guidelines. Significant mentions of GM were counted and divided between epidemiology, diagnosis, and therapeutics. The qualitative and semi-quantitative analysis of information relating to GM was performed. Data on the number of citations of papers with a title concerning GM and the prevalence and role of women in guidelines' authorship were also analyzed. Results: Less than 50% of guidelines had a section dedicated to GM. Only nine guidelines were led by a woman, and 144/567 authors were female. In the most recent guidelines and in those with at least 30% of female authors, there was an increased mention of GM. On average, guidelines had four significant mentions of GM regarding epidemiology, two regarding diagnosis, and one regarding therapy. Articles with titles concerning GM made up, on average, 1.5% of the total number of citations. Conclusions: Although sex differences play a significant role in most clinical scenarios, ESC guidelines still do not sufficiently account for this. The problem does not seem to solely lie in the guidelines, but in the lack of attention to GM in research needed for their preparation.

Effect of Coenzyme Q10 on Physical Performance in Older Adults with Statin-Associated Asthenia: A Double-Blind, Randomized, Placebo-Controlled Clinical Trial.

Background: Available evidence from randomized clinical trials is contrasting and definitely inconclusive in determining whether or not CoQ10 dietary supplementation is advisable in patients with statin intolerance or poor statin tolerability. Methods: This randomized, double-blind, placebo-controlled clinical study aimed at investigating the effect of chronic dietary supplementation with coenzyme Q10 (CoQ10) phytosome on physical performance in older adults with a ≥3-month history of statin-associated asthenia. The study's participants were randomized to either a placebo or 300 mg daily CoQ10 phytosome (equivalent to 60 mg CoQ10; Ubiqsome®, Indena SpA, Milan, Italy). Asthenia, handgrip strength (HGs), 2-min step test (2MST), and 1-min sit-to-stand (STS) repetitions were assessed at baseline and at 8-week follow-up. Results: After the first 4 weeks of dietary supplementation, individuals taking CoQ10 phytosome showed a greater improvement in asthenia compared to the placebo group (p < 0.05). Even more significantly, at 8-week follow-up, participants receiving CoQ10 showed substantial improvements in asthenia (-30.0 ± 20.0%), HGS (+29.8 ± 3.6%), 2MST (+11.1 ± 1.8%), and 1-min STS repetitions (+36.4 ± 3.9%) compared to both baseline and placebo (p < 0.05). Conclusions: According to our findings, chronic dietary supplementation with CoQ10 phytosome significantly enhances physical performance in older adults with statin-associated asthenia. This could have relevant implications for improving the compliance of older adults with statin treatment.

Risk of Cardiovascular Events in Metabolically Healthy Overweight or Obese Adults: Role of LDL-Cholesterol in the Stratification of Risk.

The objective of this study was to investigate the longitudinal association of metabolically healthy overweight/obese adults with major adverse cardiovascular events (MACE) and the effect of LDL-cholesterol levels on this association. This study was conducted with 15,904 participants from the URRAH study grouped according to BMI and metabolic status. Healthy metabolic status was identified with and without including LDL-cholesterol. The risk of MACE during 11.8 years of follow-up was evaluated with multivariable Cox regressions. Among the participants aged <70 years, high BMI was associated with an increased risk of MACE, whereas among the older subjects it was associated with lower risk. Compared to the group with normal weight/healthy metabolic status, the metabolically healthy participants aged <70 years who were overweight/obese had an increased risk of MACE with an adjusted hazard ratio of 3.81 (95% CI, 1.34-10.85, p = 0.012). However, when LDL-cholesterol < 130 mg/dL was included in the definition of healthy metabolic status, no increase in risk was found in the overweight/obese adults compared to the normal weight individuals (hazard ratio 0.70 (0.07-6.71, p = 0.75). The present data show that the risk of MACE is increased in metabolically healthy overweight/obese individuals identified according to standard criteria. However, when LDL-cholesterol is included in the definition, metabolically healthy individuals who are overweight/obese have no increase in risk.

Estimated impact of guidelines-based initiation of dual antihypertensive therapy on long-term cardiovascular outcomes in 1.1 million individuals.

AIMS: Guidelines recommend initiation of dual combination antihypertensive therapy, preferably single-pill combination (SPC), in most patients with hypertension. Evidence on narrowing gaps in clinical practice relative to guidelines is limited. METHODS AND RESULTS: Monte Carlo simulation was applied to 1.1 million patients qualifying for dual combination therapy from a previously conducted retrospective analysis of clinical practice, hospital statistics, and national statistics in the UK. We provide 10-year Kaplan-Meier event rates for the primary endpoint representing a composite of nonfatal myocardial infarction, nonfatal stroke (ischemic or hemorrhagic), nonfatal heart failure hospitalization or cardiovascular death. Cox model results from a previously conducted study were utilized to estimate baseline risk, together with evidence on risk reduction from the Blood Pressure Lowering Treatment Trialists' Collaboration (BPLTTC) meta-analysis and published evidence on BP-lowering efficacy of antihypertensive therapies. In the overall population, estimated 10-year event rates for the primary endpoint in patients with 100% persistence in monotherapy were 17.0% for irbesartan (I) and 17.6% for ramipril (R). These rates were only modestly better than that observed in clinical practice (17.8%). In patients with 100% persistence in dual therapy, estimated event rates were 13.6% for combinations of Irbesartan + Amlodipine (ARR = 8.7% compared to untreated) and 14.3% for Ramipril + Amlodipine (ARR = 8.0% compared to untreated). The absolute risk of the primary endpoint was reduced by 15.9% in patients with ASCVD and 6.6% in those without ASCVD. Similarly, the absolute risk was reduced by 11.7% in diabetics and 7.8% in those without diabetes. CONCLUSION: This study represents the first to investigate guidelines-based treatment in hypertensive patients and demonstrates the opportunity for considerable risk reduction by ensuring recommended dual therapy in clinical practice, particularly in the form of SPC with high persistence, relative to no treatment or monotherapy.

A Randomized, Double-Blind, Placebo-Controlled Clinical Trial on the Effect of a Dietary Supplement Containing Dry Artichoke and Bergamot Extracts on Metabolic and Vascular Risk Factors in Individuals with Suboptimal Cholesterol Levels.

The aim of this study was to assess whether dietary supplementation with a nutraceutical blend comprising extracts of bergamot and artichoke-both standardized in their characteristic polyphenolic fractions-could positively affect serum lipid concentration and insulin sensitivity, high-sensitivity C-reactive protein (hs-CRP), and indexes of non-alcoholic fatty liver disease (NAFLD) in 90 healthy individuals with suboptimal cholesterol levels. Participants were randomly allocated to treatment with a pill of either active treatment or placebo. After 6 weeks, the active-treated group experienced significant improvements in levels of triglycerides (TG), apolipoprotein B-100 (Apo B-100), and apolipoprotein AI (Apo AI) versus baseline. Total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), non-high density lipoprotein cholesterol (Non-HDL-C), and hs-CRP also significantly decreased in the active-treated group compared to both baseline and placebo. At the 12-week follow-up, individuals allocated to the combined nutraceutical experienced a significant improvement in TC, LDL-C, Non-HDL-C, TG, Apo B-100, Apo AI, glucose, alanine transaminase (ALT), gamma-glutamyl transferase (gGT), hs-CRP, several indexes of NAFLD, and brachial pulse volume (PV) in comparison with baseline. Improvements in TC, LDL-C, Non-HDL-C, TG, fatty liver index (FLI), hs-CRP, and endothelial reactivity were also detected compared to placebo (p < 0.05 for all). Overall, these findings support the use of the tested dietary supplement containing dry extracts of bergamot and artichoke as a safe and effective approach for the prevention and management of a broad spectrum of cardiometabolic disorders.

Serum Uric Acid, Hypertriglyceridemia, and Carotid Plaques: A Sub-Analysis of the URic Acid Right for Heart Health (URRAH) Study.

High levels of serum uric acid (SUA) and triglycerides (TG) might promote high-cardiovascular-risk phenotypes, including subclinical atherosclerosis. An interaction between plaques xanthine oxidase (XO) expression, SUA, and HDL-C has been recently postulated. Subjects from the URic acid Right for heArt Health (URRAH) study with carotid ultrasound and without previous cardiovascular diseases (CVD) (n = 6209), followed over 20 years, were included in the analysis. Hypertriglyceridemia (hTG) was defined as TG ≥ 150 mg/dL. Higher levels of SUA (hSUA) were defined as ≥5.6 mg/dL in men and 5.1 mg/dL in women. A carotid plaque was identified in 1742 subjects (28%). SUA and TG predicted carotid plaque (HR 1.09 [1.04-1.27], p < 0.001 and HR 1.25 [1.09-1.45], p < 0.001) in the whole population, independently of age, sex, diabetes, systolic blood pressure, HDL and LDL cholesterol and treatment. Four different groups were identified (normal SUA and TG, hSUA and normal TG, normal SUA and hTG, hSUA and hTG). The prevalence of plaque was progressively greater in subjects with normal SUA and TG (23%), hSUA and normal TG (31%), normal SUA and hTG (34%), and hSUA and hTG (38%) (Chi-square, 0.0001). Logistic regression analysis showed that hSUA and normal TG [HR 1.159 (1.002 to 1.341); p = 0.001], normal SUA and hTG [HR 1.305 (1.057 to 1.611); p = 0.001], and the combination of hUA and hTG [HR 1.539 (1.274 to 1.859); p = 0.001] were associated with a higher risk of plaque. Our findings demonstrate that SUA is independently associated with the presence of carotid plaque and suggest that the combination of hyperuricemia and hypertriglyceridemia is a stronger determinant of carotid plaque than hSUA or hTG taken as single risk factors. The association between SUA and CVD events may be explained in part by a direct association of UA with carotid plaques.

Oral anticoagulation in patients with left ventricular thrombus: a systematic review and meta-analysis.

AIMS: Direct oral anticoagulants (DOACs) are increasingly used off-label to treat patients with left ventricular thrombus (LVT). We analysed available meta-data comparing DOACs and vitamin K antagonists (VKAs) for efficacy and safety. METHODS: We conducted a systematic search and meta-analysis of observational and randomized data comparing DOACs vs. VKAs in patients with LVT. Endpoints of interest were stroke or systemic embolism, thrombus resolution, all-cause death, and a composite bleeding endpoint. Estimates were pooled using a random-effects model meta-analysis, and their robustness was investigated using sensitivity and influential analyses. RESULTS: We identified 22 articles (18 observational studies, 4 small randomized clinical trials) reporting on a total of 3587 patients (2489 VKA vs. 1098 DOAC therapy). The pooled estimates for stroke or systemic embolism [odds ratio (OR): 0.81; 95% confidence interval (CI): 0.57, 1.15] and thrombus resolution (OR: 1.12; 95% CI: 0.86, 1.46) were comparable, and there was low heterogeneity overall across the included studies. The use of DOACs was associated with lower odds of all-cause death (OR: 0.65; 95% CI: 0.46, 0.92) and a composite bleeding endpoint (OR: 0.67; 95% CI: 0.47, 0.97). A risk of bias was evident particularly for observational reports, with some publication bias suggested in funnel plots. CONCLUSION: In this comprehensive analysis of mainly observational data, the use of DOACs was not associated with a significant difference in stroke or systemic embolism, or thrombus resolution, compared with VKA therapy. The use of DOACs was associated with a lower rate of all-cause death and fewer bleeding events. Adequately sized randomized clinical trials are needed to confirm these findings, which could allow a wider adoption of DOACs in patients with LVT.

May Measure Month 2022 in Italy: A Focus on Fixed-dose Combination, Therapeutic Adherence, and Medical Inertia in a Nationwide Survey.

INTRODUCTION: Hypertension is the main risk factor for cardiovascular diseases (CVD). Notably, only about half of hypertensive patients manage to achieve the recommended blood pressure (BP) control. Main reasons for the persistence of uncontrolled BP during treatment are lack of compliance on the patients' side, and therapeutic inertia on physicians' side. METHODS: During the global BP screening campaign "May Measure Month" (MMM) (May 1st to July 31st, 2022), a nationwide, cross-sectional, opportunistic study endorsed by the Italian Society of Hypertension was conducted on volunteer adults ≥ 18 years to raise awareness of the health issues surrounding high BP. A questionnaire on demographic/clinical features and questions on the use of fixed-dose single-pills for the treatment of hypertension was administered. BP was measured with standard procedures. RESULTS: A total of 1612 participants (mean age 60.0±15.41 years; 44.7% women) were enrolled. Their mean BP was 128.5±18.1/77.1±10.4 mmHg. About half of participants were sedentary, or overweight/obese, or hypertensive. 55.5% individuals with complete BP assessment had uncontrolled hypertension. Most were not on a fixed-dose combination of antihypertensive drugs and did not regularly measure BP at home. Self-reported adherence to BP medications was similar between individuals with controlled and uncontrolled BP (95% vs 95.5%). CONCLUSIONS: This survey identified a remarkable degree of therapeutic inertia and poor patients' involvement in the therapeutic process and its monitoring in the examined population, underlining the importance of prevention campaigns to identify areas of unsatisfactory management of hypertension, to increase risk factors' awareness in the population with the final purpose of reducing cardiovascular risk.

Enhancing stroke risk prediction in patients with transient ischemic attack: insights from a prospective cohort study implementing fast-track care.

Background and aims: Fast-track care have been proved to reduce the short-term risk of stroke after transient ischemic attack (TIA). We aimed to investigate stroke risk and to characterize short- and long-term stroke predictors in a large cohort of TIA patients undergoing fast-track management. Methods: Prospective study, enrolling consecutive TIA patients admitted to a Northern Italy emergency department from August 2010 to December 2017. All patients underwent fast-track care within 24 h of admission. The primary outcome was defined as the first stroke recurrence at 90 days, 12 and 60 months after TIA. Stroke incidence with 95% confidence interval (CI) at each timepoint was calculated using Poisson regression. Predictors of stroke recurrence were evaluated with Cox regression analysis. The number needed to treat (NNT) of fast-track care in preventing 90-day stroke recurrence in respect to the estimates based on baseline ABCD2 score was also calculated. Results: We enrolled 1,035 patients (54.2% males). Stroke incidence was low throughout the follow-up with rates of 2.2% [95% CI 1.4-3.3%] at 90 days, 2.9% [95% CI 1.9-4.2%] at 12 months and 7.1% [95% CI 5.4-9.0%] at 60 months. Multiple TIA, speech disturbances and presence of ischemic lesion at neuroimaging predicted stroke recurrence at each timepoint. Male sex and increasing age predicted 90-day and 60-month stroke risk, respectively. Hypertension was associated with higher 12-month and 60-month stroke risk. No specific TIA etiology predicted higher stroke risk throughout the follow-up. The NNT for fast-track care in preventing 90-day stroke was 14.5 [95% CI 11.3-20.4] in the overall cohort and 6.8 [95% CI 4.6-13.5] in patients with baseline ABCD2 of 6 to 7. Conclusion: Our findings support the effectiveness of fast-track care in preventing both short- and long-term stroke recurrence after TIA. Particular effort should be made to identify and monitor patients with baseline predictors of higher stroke risk, which may vary according to follow-up duration.

There are those who would like zero LDL cholesterol.

The overwhelming evidence that the reduction of LDL cholesterol (LDLc) levels is associated with a parallel reduction in cardiovascular (CV) risk has led the scientific community to progressively and constantly reduce the optimal therapeutic targets of LDLc, both in patients with known CV disease and in patients undergoing primary prevention. The recent introduction of proprotein convertase subtilisin/kexin type 9 inhibitors has allowed clinicians to observe reductions in LDLc levels that go well beyond the limits set by the main international guidelines; following the 'the lower the better' paradigm, it is natural to ask how low LDLc can be reduced, whether this intervention is associated with a further reduction in CV risk and, above all, whether there are no issues related to safety in the use of polypharmacotherapies that determine an extreme reduction in LDLc levels. The purpose of this article is to summarize the main scientific evidence on the topic, trying to provide an answer to all clinicians who 'would like their LDLc to be-almost-zero'.

Targeting the sympathetic nervous system with the selective imidazoline receptor agonist moxonidine for the management of hypertension: an international position statement.

Hypertension is often linked with metabolic risk factors that share common pathophysiological pathways. Despite wide-spread availability of multiple drug classes, optimal blood pressure (BP) control remains challenging. Increased central sympathetic outflow is frequently neglected as a critical regulator of both circulatory and metabolic pathways and often remains unopposed therapeutically. Selective imidazoline receptor agonists (SIRAs) effectively reduce BP with a favorable side effect profile compared with older centrally acting antihypertensive drugs. Hard outcome data in hypertension, such as prevention of stroke, heart and kidney diseases, are not available with SIRAs. However, in direct comparisons, SIRAs were as effective as angiotensin-converting enzyme inhibitors, ß-blockers, calcium channel blockers, and diuretics in lowering BP. Other beneficial effects on metabolic parameters in hypertensive patients with concomitant overweight and obesity have been documented with SIRAs. Here we review the existing evidence on the safety and efficacy of moxonidine, a widely available SIRA, compared with common antihypertensive agents and provide a consensus position statement based on inputs from 12 experts from Europe and Australia on SIRAs in hypertension management.

Comparison Between a Single-Lead ECG Garment Device and a Holter Monitor: A Signal Quality Assessment.

Wearable electronics are increasingly common and useful as health monitoring devices, many of which feature the ability to record a single-lead electrocardiogram (ECG). However, recording the ECG commonly requires the user to touch the device to complete the lead circuit, which prevents continuous data acquisition. An alternative approach to enable continuous monitoring without user initiation is to embed the leads in a garment. This study assessed ECG data obtained from the YouCare device (a novel sensorized garment) via comparison with a conventional Holter monitor. A cohort of thirty patients (age range: 20-82 years; 16 females and 14 males) were enrolled and monitored for twenty-four hours with both the YouCare device and a Holter monitor. ECG data from both devices were qualitatively assessed by a panel of three expert cardiologists and quantitatively analyzed using specialized software. Patients also responded to a survey about the comfort of the YouCare device as compared to the Holter monitor. The YouCare device was assessed to have 70% of its ECG signals as "Good", 12% as "Acceptable", and 18% as "Not Readable". The R-wave, independently recorded by the YouCare device and Holter monitor, were synchronized within measurement error during 99.4% of cardiac cycles. In addition, patients found the YouCare device more comfortable than the Holter monitor (comfortable 22 vs. 5 and uncomfortable 1 vs. 18, respectively). Therefore, the quality of ECG data collected from the garment-based device was comparable to a Holter monitor when the signal was sufficiently acquired, and the garment was also comfortable.

Serum uric acid to eGFR ratio correlates with adverse outcomes in elderly hospitalized for acute heart failure.

BACKGROUND: Serum uric acid (SUA) is a known biomarker of severity in acute heart failure (AHF), reflecting the intricate interplay between cardiovascular and metabolic dysfunction. Since SUA can increase in response to worsening kidney function, and subjects with AHF often have cardiorenal syndrome or are on diuretic therapy, we tested whether the ratio of SUA to eGFR might provide prognostic value in elderly hospitalized for AHF. METHODS: The BOTERO-AHF Study (BOlogna study of Therapies, Epidemiology and Radiodiagnostic Outcomes in Acute Heart Failure patients) included 293 patients admitted for AHF who were consecutively enrolled from January 2020 onwards. We compared the baseline characteristics of participants who had a composite outcome (CO) (n = 203) of death or re-hospitalization for AHF within 12 months from discharge to those without CO (n = 90), and we assessed the prognostic impact of SUA/eGFR for 12-months CO. RESULTS: SUA/eGFR was significantly higher in participants who experienced a CO within 12 months from discharge for AHF, compared to those who did not experience any CO (17.8 (16.6) vs. 13.7 (12.1) mg/dl/ml/min*100, p = 0.008). SUA/eGFR, and not SUA alone, was associated with an increase in the rate of CO (unadjusted HR 1.011, CI 95% 1.004-1.019, p = 0.003). This association lost significance in participants under treatment with xanthine oxidase inhibitors but remained significant after adjustment for multiple confounders. CONCLUSION: The SUA/ eGFR ratio provides prognostic value in elderly patients hospitalized for AHF. Future studies may clarify if SUA/eGFR and XOI may represent novel diagnostic and therapeutic approaches for subgroups of patients with AHF.

Validation of a New and Straightforward Algorithm to Evaluate Signal Quality during ECG Monitoring with Wearable Devices Used in a Clinical Setting.

BACKGROUND: Wearable devices represent a new approach for monitoring key clinical parameters, such as ECG signals, for research and health purposes. These devices could outcompete medical devices in terms of affordability and use in out-clinic settings, allowing remote monitoring. The major limitation, especially when compared to implantable devices, is the presence of artifacts. Several authors reported a relevant percentage of recording time with poor/unusable traces for ECG, potentially hampering the use of these devices for this purpose. For this reason, it is of the utmost importance to develop a simple and inexpensive system enabling the user of the wearable devices to have immediate feedback on the quality of the acquired signal, allowing for real-time correction. METHODS: A simple algorithm that can work in real time to verify the quality of the ECG signal (acceptable and unacceptable) was validated. Based on simple statistical parameters, the algorithm was blindly tested by comparison with ECG tracings previously classified by two expert cardiologists. RESULTS: The classifications of 7200 10s-signal samples acquired on 20 patients with a commercial wearable ECG monitor were compared. The algorithm has an overall efficiency of approximately 95%, with a sensitivity of 94.7% and a specificity of 95.3%. CONCLUSIONS: The results demonstrate that even a simple algorithm can be used to classify signal coarseness, and this could allow real-time intervention by the subject or the technician.
