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: Hypertension is associated with changes in microcirculation, while increased blood pressure (BP) during exercise stress testing has been correlated with adverse outcomes.

Aim: To evaluate the relationship of microcirculation with exercise BP response in hypertensive individuals.

Methods: 105 hypertensive individuals underwent exercise stress testing and nail-fold videocapillaroscopy assessment, in order to evaluate the relationship of BP response to exercise with capillary density.

Results: A significant negative correlation between diastolic BP at 1-minute recovery and capillary density was revealed (Pearson's r = -0.365, p = 0.043). A significant negative correlation was also observed between capillary density and peak heart rate (HR) (Pearson's r = -0.364, p = 0.024) and HR increase from stage 1 to 2 (Pearson's r = -0.746, p = 0.013).

Conclusion: Capillary rarefaction is associated with an abnormal BP and HR response to exercise, highlighting the role of microcirculation in BP regulation during exercise.

Introduction: Obstructive sleep apnea (OSA) presents a significant global health concern, affecting a substantial portion of the population, particularly among young and middle-aged adults.

Aim: This review aims to assess the efficacy of continuous positive airway pressure (CPAP) compared to antihypertensive medications in managing OSA-related hypertension.

Methods: A comprehensive literature search was conducted across multiple databases, yielding studies published from 2000 to March 2024 that investigated CPAP, antihypertensives, or their combination therapy in OSA patients. Six definitive studies were analyzed, including two randomized controlled trials (RCTs), one randomized double-blind placebo-controlled crossover trial, one placebo-controlled trial, one open-label multicenter trial, and one longitudinal cohort study. These studies comprised 939 participants, with intervention durations ranging from four weeks to six months.

Results: Analysis of CPAP monotherapy revealed variable efficacy, with some studies demonstrating significant reductions in 24-hour mean blood pressure and diastolic pressure, while others reported non-significant changes. CPAP therapy combined with antihypertensives showed additive effects, particularly in reducing office blood pressure measurements. Antihypertensive medications, such as valsartan, exhibited superior efficacy in reducing blood pressure compared to CPAP alone. Factors influencing therapy effectiveness included CPAP compliance, patient characteristics, and coexisting comorbidities. Patients with good CPAP adherence experienced greater reductions in blood pressure. The duration of exposure to OSA and the type of hypertension also impacted the therapy response.

Conclusion: While CPAP and antihypertensive medications offer significant benefits in managing hypertension among OSA patients, challenges such as CPAP intolerance and medication side effects exist. Personalized treatment considering individual patient factors is crucial for optimal management.

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.

Since randomized clinical trials currently do not support continuous positive airway pressure treatment of asymptomatic obstructive sleep apnea (OSA) we proposed the Obesity, Symptoms, and CARdiovascular assessment (OSCAR) algorithm to aid clinicians in the management of asymptomatic low-risk moderate-severe OSA, focusing on weight loss, symptoms and cardiovascular disease (CVD) risk assessment. Exploiting the data of the Sleep Heart Health Study we selected subjects with a body mass index (BMI) < 30 Kg/m², no history of CVD or sleepiness and compared 552 patients with moderate-severe OSA (OSCAR(-)) to 916 individuals without OSA (No-OSA). After adjusting for age, gender, and BMI, there was no significant difference in the risk of major adverse cardiovascular events (MACE) between OSCAR(-) and No-OSA (1.05; 95%CI 0.81-1.37). The study suggests that low-risk moderate-severe OSA patients may not have a greater risk of MACE compared to those without OSA and highlights the need for further research on this topic.

The Sudan conflict has severely impacted hypertension management, exacerbating the condition through chronic stress, disrupted healthcare, and lifestyle changes. Hypertension, a major risk factor for cardiovascular diseases, worsens with war-related stress and limited access to medications due to damaged healthcare infrastructure. Additionally, displacement, economic hardship, and food insecurity contribute to poor diets and reduced physical activity, further complicating blood pressure control. This article highlights the urgent need for adaptive healthcare strategies, such as mobile clinics and international aid, to address these challenges. A concerted effort is required to improve hypertension management and outcomes in conflict-affected populations.

Introduction: Elevated serum total cholesterol levels, very low-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, or a decreased serum high-density lipoprotein cholesterol concentration characterize dyslipidemia. Antisense Oligonucleotide therapy in dyslipidemia targets apolipoprotein B (ApoB), an essential component of low-density lipoprotein (LDL) associated with atherosclerosis development.

Aim: This review aims to critically evaluate the efficacy and safety of this group of medications in mitigating dyslipidemia in at-risk individuals and its potential role in advancing personalized medicine in the management of dyslipidemias.

Methods: A detailed search was conducted from multiple databases adhering to the PRISMA guidelines. Clinical trials and randomized controlled trials on antisense oligonucleotides for management of dyslipidemias were included, excluding non-English studies, case reports and all forms of reviews. Data was screened, with duplicates removed, and key findings were synthesized using a narrative approach.

Results and conclusion: The potential of antisense oligonucleotides (ASOs) to treat dyslipidemia and other disorders has attracted much interest. Several studies and clinical trials have been conducted on the safety and tolerability of ASOs for dyslipidemia. Although statins are the mainstay management of hypercholesterolemia, there is evidence from clinical trials that ASOs can even be more effective with little to no side effects. Novel therapeutic approaches such as antisense oligonucleotides (ASOs) offer tailored therapeutic alternatives. ASOs such as Mipomersen and Volanesorsen provide additional treatment options for patients with inherited lipid abnormalities by lowering certain atherogenic lipoproteins such as apo B and ApoC-III, respectively.

West African (WA) migrants in Europe have higher hypertension rates than the host populations. For African migrants, guidelines recommend diuretics and/or calcium channel blockers (CCB) for primary cardiovascular disease prevention, but data on antihypertensive medication (AHM) prescription patterns or related hypertension control rates are lacking. We assessed AHM prescription patterns and its relation to hypertension control among hypertensive WA migrants in the Netherlands compared to the host population. Cross-sectional data from WA or Dutch origin participants from the HELIUS study were used. Participants with treated hypertension and without diabetes, cardiovascular disease, or microalbuminuria were selected. We used logistic and linear regression analyses to assess the association between AHM categories and hypertension control rates (systolic blood pressure (BP) ≤ 140 mmHg and diastolic BP ≤ 90 mmHg) and the systolic BP levels. We compared 999 WA participants and 314 Dutch participants. Hypertension control rates were lower in the WA origin compared to Dutch origin participants (44.3% versus 58.0%, p < 0.001). For WA participants, prescription rates for any AHM category were: CCB (54.8%), diuretics (18.5%) beta-blocking agents (27.3%) and renin-angiotensin system blockers (52.6%). Prescription rates were higher for CCB and similar for diuretics compared to the Dutch participants. Neither CCB nor diuretics were associated with better control rates. Compared to Dutch participants, West African participants had similar diuretic prescriptions but significantly higher prescriptions for CCB. However, neither medications was associated with better hypertension control. Future research should explore physician and patient factors to improve hypertension control.

Introduction: Vascular Ehlers-Danlos syndrome (vEDS) is an inherited connective tissue disorder characterized by arterial fragility. Celiprolol is a β1-adrenoceptor antagonist with partial β2 agonist activity that has been shown to reduce rates of vascular events in this setting, though the underlying mechanisms are not yet fully understood. Moreover, very few echocardiographic data are available in patients with vEDS.

Aim: To perform a comprehensive echocardiographic assessment of a cohort of patients with vEDS with or without celiprolol therapy compared with healthy subjects.

Methods: Twenty patients with genetically confirmed diagnosis of vEDS followed at our Institution (University Hospital of Brescia, Italy) were divided into two groups according to whether or not they were on celiprolol therapy at the maximum recommended dose (400 mg daily) for at least 12 months. Both groups were compared to 10 healthy individuals matched for sex, age, body mass index (BMI), and office blood pressure (BP) values. Each participant underwent transthoracic echocardiography with tissue Doppler analysis (TDI) for a comprehensive evaluation of cardiac structure and function.

Results: Mean age was 35 years and mean BMI was 21.6 kg/m². Female sex was prevalent (60%). Left ventricular (LV) internal diameter values tended to be lower in patients with untreated vEDS than in healthy controls (4.33 vs 4.74 cm, respectively), though this difference was not statistically significant. Similar data were observed for LV mass index (56.9 vs 68.6 g/m²), stroke volume (56.6 vs 71.6 mL), and E/A ratio (1.26 vs 1.66), whereas an opposite trend was observed for e' lateral (13.2 vs 12.2 cm/s). No statistically significant difference was found between groups in terms of other parameters of LV mass, systolic and diastolic function. A normal LV geometry was found in all the cases. Indices of mechano-energetic efficiency and ventricular-arterial coupling were also similar between groups. No patient presented with aortic root dilation, mitral valve prolapse, valve insufficiency of more than mild degree, or valve stenosis of any degree.

Conclusion: Our study suggests that patients with vEDS have normal cardiac mass and geometry, as well as normal systolic and diastolic function. Celiprolol therapy does not seem to significantly influence such aspects. Compared with vascular imaging, less stringent follow-up with echocardiography seems reasonable in this setting. Future studies with prospective design should confirm these aspects.
