Introduction: Serum uric acid (SUA), the final product of purine metabolism, is an independent risk factor for cardiovascular (CV) disease. Since SUA levels depend on renal function, SUA to serum creatinine ratio (SUA/sCr) is emerging as a more specific biomarker of CV risk.

Aim: To evaluate in hospitalized patients with cardiorenal multimorbidity (CRM) if the SUA/sCr ≥ 5.35 is associated with clinical outcomes. The primary outcome was in-hospital mortality. The secondary outcome was the composite of all-cause of mortality and adverse clinical events.

Methods: We conducted a retrospective review of medical records from consecutive CRM inpatients admitted to the medical ward. The composite endpoint was calculated as all-cause mortality and adverse clinical events such as acute coronary syndrome, stroke, infections, and renal replacement therapy.

Results: In our cohort, 141 patients (mean age of 75.6 ± 10.2 years) were identified with CRM. In-hospital mortality occurred in 17 patients (16%), and 64 patients (60.4%) experienced adverse clinical outcomes. Among the 106 patients, 20 (18.9%) had an SUA/sCr ≥ 5.35, while 86 (81.1%) had an SUA/sCr < 5.35. Male gender was significantly associated with SUA/sCr ≥ 5.35 (p = 0.007). In-hospital mortality was significantly higher in patients with SUA/sCr ≥ 5.35 (p = 0.010), and a positive correlation with adverse clinical outcomes was documented in this subgroup (p = 0.012).

Conclusion: in patients with CRM, SUA/sCr ≥ 5.35 is associated with increased in-hospital mortality and worse clinical outcomes. The ratio and related cut-off value of SUA/sCr could represent a useful biomarker to assess in-hospital complications in CRM patients.

Hypertension and hypercholesterolemia often occur in the same individuals, increasing the risk of major cardiovascular (CV) outcomes, including myocardial infarction, stroke, CV death, as well as other CV complications. Concomitant management of these condition now represent a crucial step to reduce individual global CV risk and improve CV disease prevention in daily clinical practice. Given the high prevalence of hypertension and hypercholesterolemia in general population and their impact on health status, several pharmacological options are currently available to achieve the recommended therapeutic targets. These drugs, mostly including statins, ezetimibe, bempedoic acid, proprotein convertase subtilisin/kexin type 9 (PCSK-9) inhibitors and inclisiran, can be used either in monotherapies or in combination therapies, with different clinical indications, therapeutic efficacy and tolerability profile. Decision among different drug classes and dosages, as well as choice between monotherapy or combination therapy (fixed or free), largely depend on individual global CV risk profile and therapeutic targets of low-density lipoprotein (LDL) cholesterol levels to be achieved under pharmacological therapy. The present consensus document represents an update of the previous document published on 2022 and endorsed by the Italian Society of Hypertension (SIIA) and the Italian Society of Cardiovascular Prevention (SIPREC). Here we propose a novel paradigm for the treatment of the patients with hypertension and hypercholesterolemia at high or very high cardiovascular risk. In addition, the pharmacological properties, and the clinical efficacy of novel agents recently approved for a tailored therapy of hypercholesterolemia in patients with atherosclerotic CV disease, including PCSK9 inhibitors and bempedoic acid, will be summarized.

In view of the growing evidence supporting more marked reductions of low-density lipoprotein cholesterol (LDL-C), according to the concept of "the lower is better" and with the availability of powerful and well tolerated lipid-lowering drugs, physicians are facing today with the clinical management of patients with very low LDL-C levels. The fear of potential risks linked to extreme reductions of LDL-C down to very low levels may lead to the de-escalation of treatments with consequent paradoxical unfavorable consequences due to the exposure to a higher cardiovascular risk. The aim of this review is to point out evidence of very low LDL-C clinical impact, with a focus on potential adverse effects. Research on cholesterol homeostasis has identified complex mechanisms which guarantee cell functions even when circulating cholesterol levels are very low. The almost complete self-sufficiency of the human body in terms of cholesterol needs is confirmed by evidence derived from genetically determined models with very low LDL-C levels. Studies on the potential harm of lowering LDL-C to very low concentrations do not confirm an increased risk of cancer or neurodegenerative disease attributable to lipid-lowering treatments, whereas evidence suggests a potential benefit in these settings. A potential increased risk of hemorrhagic stroke has been reported, suggesting tight monitoring and control of blood pressure should be implemented in patients with very low LDL-C levels. With regard to statin treatment, a dose-dependent increased risk of newly diagnosed diabetes has been reported. This adverse effect has not been found with more recently approved lipid-lowering drugs.

Introduction: Accurate risk assessment is critical in cardiovascular (CV) prevention, yet physicians often underestimate CV risk, leading to inadequate preventive measures.

Aim: This study evaluates the concordance between physician-perceived CV risk and calculated CV risk in a primary prevention setting.

Methods: This cross-sectional study included primary prevention patients from the Cardiology Outpatient Clinic of Caserta Hospital, Italy. Two independent cardiologists evaluated the physician-perceived risk, and a third resolved discrepancies. CV risk was calculated using SCORE2 for patients with 70 years or less and SCORE2-OP for those with more than 70 years. The concordance between perceived and calculated risks was assessed using Cohen's kappa coefficient. Multivariate logistic regression analysis was performed to examine the influence of risk estimation on achieving low-density lipoprotein cholesterol (LDL-C) targets recommended by the ESC.

Results: 389 patients had complete data for CV risk calculation. Physician-perceived risk categorized 8.7% of patients as low/moderate, 37.8% as high, and 53.5% as very-high risk. In contrast, calculated CV risk according to the SCORE2/SCORE2-OP classified 8% as low/moderate, 5.7% as high, and 86.4% as very-high risk. The concordance between perceived and calculated CV risk was poor (Cohen's kappa 0.208, p < 0.001). Underestimated patients reached LDL-C targets in 16% of cases, well-estimated in 34.5%, and overestimated in 76.9%. Statin use was significantly lower in patients with underestimated CV risk (29.2%) compared to well-estimated (50%) and overestimated (76.9%) groups (p < 0.001). Multivariate analysis showed that patients with overestimated risk were more likely to achieve LDL-C targets (OR 5.33, CI 1.33-21.42, p = 0.018), whereas underestimated patients were 47% less likely (OR 0.53, CI 0.3-0.93, p = 0.027).

Conclusions: A significant discrepancy exists between physician-perceived and calculated CV risk, leading to risk underestimation in over one-third of patients. This underestimation is associated with lower LDL-C target achievement and reduced statin use.

Introduction: Cardiovascular diseases (CVD) represent the leading cause of morbidity and mortality for women worldwide, yet they are often unaware of this heavy burden.

Aim: To assess cardiovascular risk awareness among Italian women.

Methods: Following World Heart Day 2023, a cardiovascular prevention campaign was conducted in Italian pharmacies to evaluate the effectiveness of screening activities offered by pharmacies and raise awareness of cardiovascular health status among Italian women. Cardiovascular risk profile and perception of CVD burden relative to other common female-specific diseases were assessed. Blood pressure (BP) measurement and ECG recording were performed.

Results: A total of 1510 women (84.7% < 70 years), enrolled at 91 pharmacies, were included. The most prevalent cardiovascular risk factor was sedentary lifestyle (57.9%), followed by overweight/obesity (44.3%), hypercholesterolemia (37.9%), hypertension (31.3%), family history of early CVD (28.7%), smoking (20.6%), and diabetes (5%). CVD and/or kidney disease were uncommon (3.6%), but 1 in 4 women was classified as being at increased cardiovascular risk, and 47.5% had some type of ECG abnormalities, requiring further assessments in 18% cases. Less than 1 in 3 women was aware of the burden represented by CVD, being the majority mostly concerned with breast cancer and osteoporosis as potential health threats.

Conclusions: The burden of cardiovascular risk factors is high, and the perception of related health threat is low among the examined sample of Italian women, supporting the urgent need to raise awareness of CVD in women as a major health issue and to undertake effective, tailored preventive strategies to reduce such risk in a timely fashion.

Introduction: A strong and well-known association exists between salt consumption, potassium intake, and cardiovascular diseases. MINISAL-SIIA results showed high salt and low potassium consumption in Italian hypertensive patients. In addition, a recent Italian survey showed that the degree of knowledge and behaviour about salt was directly interrelated, suggesting a key role of the educational approach.

Aim: The present multicentre randomised controlled trial study aimed to evaluate the efficacy of a short-time dietary educational intervention by a physician, only during the first visit, on sodium and potassium intake in hypertensive patients.

Methods: Two-hundred-thirty hypertensive subjects participating in the MINISAL-SIIA study were enrolled for this study. After the randomisation, the participants were stratified into the educational intervention (EI) group (n = 109) and control group (C) (n = 121). Anthropometric indexes and blood pressure (BP) measurements were taken in the single-centre, and 24-hour urinary sodium (UrNa) and potassium (UrK) excretion were centrally measured.

Results: After 3 months, there was a reduction in BP, UrNa, and body weight, and an increase in UrK in EI. By contrast, a lower decrease in BP was found in the C group, and a slight rise in UrNa and no substantial change in UrK were revealed. BP changes were positively and significantly associated with changes in UrNa only in EI.

Conclusion: The main results of this trial indicate that a single brief educational intervention by a physician can lead to a reduction in salt intake and BP, and increased potassium consumption in hypertensive patients, without adverse effects.

Posterior reversible encephalopathy syndrome (PRES) may present with different clinical symptoms including visual disturbance, headache, seizures and impaired consciousness. Brain MRI shows oedema, usually involving the posterior subcortical regions. Triggering factors include hypertension and obstructive sleep apnea syndrome. The mechanism underlying PRES is under debate, but endothelial dysfunction is implicated. Treatment goals of PRES are gradual blood pressure (BP) lowering to avoid sudden hypoperfusion of vital organs and prevention and management of seizures. PRES usually has a favorable prognosis, but delayed diagnosis and treatment may lead to cardiovascular morbidity, mortality or irreversible neurological deficits.

Introduction: Carotid IMT is a recognized marker for early atherosclerotic changes and a predictor of future CV events. Previous studies showed 11% increased risk of myocardial infarction with each 0.1 mm incremental increase of carotid IMT. In general population, LDL cholesterol levels are positively correlated with carotid IMT in both cross-sectional and longitudinal studies while its role in elite athletes remains understudied.

Aim: This study aimed to investigate the correlation between persistent lipid profile alterations and early markers of atherosclerosis, specifically carotid IMT, in a cohort of elite athletes.

Methods: We included 302 athletes serially evaluated for a prolonged time period. Anthropometric data, blood tests for lipid profiles, and carotid IMT measurements were collected. Dyslipidemia was defined as LDL ≥ 116 mg/dL, and persistent elevation when LDL values remained above the threshold limits in at least three pre-participation screenings. Categorical variables were expressed as frequencies and percentages and were compared using Fisher's exact test or Chi-square test, as appropriate.

Results: 91 athletes (30.1%) had persistently elevated LDL levels. Dyslipidemic athletes were older (30.7 ± 5.7 vs. 29.1 ± 4.1 years, p = 0.008), had higher BMI (p = 0.032), and a higher prevalence of obesity (5.5% vs. 0.5%, p = 0.004) compared to those with normal lipid profiles. Additionally, they had higher total cholesterol (p < 0.0001) and triglycerides (p < 0.0001) but similar HDL levels (p = 0.213). Globally, athletes with altered LDL profiles over long-time period showed higher IMT (0.60 ± 0.10 mm vs. 0.57 ± 0.07 mm, p = 0.014). In particular, longer exposure to elevated LDL was significantly associated with increased IMT (0.61 ± 0.12 mm vs. 0.57 ± 0.06 mm, p = 0.035).

Conclusions: Our study highlights the association between persistently elevated LDL-C and increased carotid IMT in elite athletes, with longer exposure time correlating with more pronounced carotid changes. These findings underscore the importance of regular monitoring of blood lipid profiles and carotid IMT measurements as a non-invasive, cost-effective method to prevent atherosclerotic vascular disease.

Aims: To systematically appraise and summarize the available evidence from published randomized controlled trials considering the effect of nebivolol on blood pressure in patients with hypertension.

Methods: Literature search was performed through Medline (via PubMed), Cochrane Library and Scopus until December 15, 2023. Double-independent study selection, data extraction and quality assessment were performed. Evidence was pooled with three-level mixed-effects meta-analysis.

Results: In total, 7,737 participants with hypertension, who were treated with nebivolol, were analyzed across 91 RCTs. Nebivolol was associated with significantly greater reduction in office systolic and diastolic BP compared to placebo (MD = - 6.01 mmHg; 95% CI = [- 7.46, - 4.55] and MD = - 5.01 mmHg; 95% CI = [- 5.91, - 4.11], respectively). Moreover, resulted a similar reduction in systolic BP (MD = - 0.22 mmHg; 95% CI = [- 0.91, 0.46]) and a significantly greater reduction in diastolic BP compared to the active comparator (MD = - 0.71 mmHg; 95% CI = [- 1.27, - 0.16]). When considering the effect of nebivolol on 24-hour ambulatory BP, notable reductions were observed compared to placebo. In contrast, compared to the active comparators, there was no significant difference in systolic BP reduction, but a significant reduction in diastolic BP favoring nebivolol. Based on moderator analyses, the impact of nebivolol on the pooled estimates remained independent of the dose of nebivolol, age, male sex, trial duration, body mass index (BMI), baseline diabetes, heart failure, and baseline systolic and diastolic BP.

Conclusion: Nebivolol, compared to placebo, showed a significant BP reduction and was non-inferior to other active comparators in terms of BP reduction.

Introduction: Hypertension and dyslipidemia are common contributors to cardiovascular disease (CVD), often occurring together. Effectively Managing both is key to reducing mortality and morbidity, but complex regimens reduce adherence.

Aim: This study investigated the comparative efficacy and safety of a three-drug regimen (TAR) containing telmisartan, amlodipine, and rosuvastatin against two-drug combinations (TA and TR) for managing hypertension and dyslipidemia.

Methods: We searched PubMed, Web of Science, Cochrane, Embase, and Scopus databases for relevant articles matching our inclusion criteria. Following the application of inclusion criteria, four studies were selected for qualitative analysis and four studies for meta-analysis.

Results: Our analysis showed TAR [n = 155] significantly reduced mean systolic blood pressure (MSSBP) at week 4 compared to TR (n = 163) (MD = -15.65 mmHg) and TA (MD = -4.63 mmHg). TAR also showed superiority over all groups (TR [n = 163], TA [n = 162]) in MSSBP reduction. For low-density lipoprotein-cholesterol (LDL-C), TAR only showed a significant difference at week 4 compared to TA (MD = -86.41 mg/dL), with no difference between TAR and TR at either week 4 or 8.

Conclusion: Our findings suggest that TAR may be a safe and effective therapeutic option for the concurrent management of hypertension and dyslipidemia. However, there is no significant difference regarding adverse events between both arms.
