Among cardiovascular diseases, hypertension is one of the main risk factors predisposing to fatal complications. Oxidative stress and chronic inflammation have been identified as potentially responsible for the development of endothelial damage and vascular stiffness, two of the primum movens of hypertension and cardiovascular diseases. Based on these data, we conducted an open-label randomized study, first, to evaluate the endothelial damage and vascular stiffness in hypertense patients; second, to test the effect of supplementation with a physiological antioxidant (melatonin 1 mg/day for 1 year) in patients with essential hypertension vs. hypertensive controls. Twenty-three patients of either gender were enrolled and randomized 1:1 in two groups (control and supplemented group). The plasmatic total antioxidant capacity (as a marker of oxidative stress), blood pressure, arterial stiffness, and peripheral endothelial function were evaluated at the beginning of the study and after 1 year in both groups. Our results showed that arterial stiffness improved significantly (p = 0.022) in supplemented patients. The endothelial function increased too, even if not significantly (p = 0.688), after 1 year of melatonin administration. Moreover, the supplemented group showed a significative reduction in TAC levels (p = 0.041) correlated with the improvement of arterial stiffness. These data suggest that melatonin may play an important role in reducing the serum levels of TAC and, consequently, in improving arterial stiffness.

BackgroundAlthough treatment options for heart failure (HF) have improved, advanced HF (AdHF) remains a challenging condition, impacting over 10% of patients with a poor prognosis. In severe cases, patients may experience resistance to or intolerance of conventional therapies, leading to frequent hospitalisations and a heightened risk of death. Vericiguat, a novel treatment for HF with reduced ejection fraction (HFrEF), has shown promise in improving outcomes for patients with worsening HF. The VICTORIA (Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction) trial demonstrated that vericiguat can reduce the risk of adverse events in patients with EF<45% following a worsening HF event. However, its safety and efficacy in AdHF patients previously receiving chronic levosimendan infusions remain unclear.Methods and resultsIn this prospective study, we evaluated the safety and tolerability of vericiguat in AdHF patients treated with monthly levosimendan infusions at our clinic. Among 18 patients, 8 were eligible for vericiguat, which was associated with better echocardiographic findings, improved quality of life and lower 1-year mortality compared with non-eligible patients. However, 37.5% of patients discontinued the drug due to symptomatic hypotension, highlighting a key challenge in managing this fragile population. Despite this, vericiguat was generally well-tolerated, and no severe adverse effects were observed.DiscussionThis study provides the first prospective evidence supporting the safe use of vericiguat in AdHF patients on chronic levosimendan. However, careful monitoring for hypotension is essential, and titration may be more difficult in this population. Further research is needed to optimise treatment strategies for these high-risk patients.

This review describes the complex interplay between inflammation, vasculopathy and fibrosis that involve the heart and peripheral small vessels, leading to endothelial stiffness, vascular damage, and early aging in patients with systemic lupus erythematosus and systemic sclerosis, which represents two different models of vascular dysfunction among systemic autoimmune diseases. In fact, despite the fact that diagnostic methods and therapies have been significantly improved in the last years, affected patients show an excess of cardiovascular mortality if compared with the general population. In addition, we provide a complete overview on the new techniques which are used for the evaluation of endothelial dysfunction in a preclinical phase, which could represent a new approach in the assessment of cardiovascular risk in these patients.

The increasing burden of cardiovascular disease (CVD) despite the progress in management entails the need of more effective preventive and curative strategies. As dietary-associated risk is the most important behavioral factor influencing global health, it appears the best target in the challenge against CVD. Although for many years, since the formulation of the cholesterol hypothesis, a nutrient-based approach was attempted for CVD prevention and treatment, in recent years a dietary-based approach resulted more effective in reducing cardiovascular risk worldwide. After the publication of randomized trials on the remarkable effects of the Mediterranean diet and the Dietary Approach to Stop Hypertension (DASH) diet on CVD, new efforts were put on research about the effects of complex dietary interventions on CVD. The purpose of this paper is to review the evidence on dietary interventions in the prevention and disease modification of CVD, focusing on coronary artery disease and heart failure, the main disease responsible for the enormous toll taken by CVD worldwide.

Ivabradine is a pure heart-rate lowering drug that is nowadays used, accordingly to the last ESC Guidelines, to reduce mortality and heart failure (HF) hospitalization in patients with HF with reduced ejection fraction and in symptomatic patiens with inappropriate sinus tachycardia. Moreover, interesting effect of ivabradine on endothelial and myocardial function and on oxidative stress and inflamation pathways are progressively emerging. The aim of this paper is to highlight newer evidences about ivabradine effect (and consequently possible future application of the drug) in pathological settings different from guidelines-based clinical practice.

We hereby report a puzzling case of multiple sclerosis (MS) relapse presenting as Takotsubo syndrome (TTS). Female, 42-years old, who presented herself to the Emergency Room of University Hospital €œASST Spedali Civili€ of Brescia, Italy, for a severe headache and a non-ST-segment elevation acute corory syndrome. Corory angiogram showed no signs of corory atherosclerosis. Upon further neurological evaluation, a diagnosis of MS relapse, related to TTS, was made, and treatment was started accordingly. The patient was discharged after 12 days after the admission, free of symptoms, and without signs of neurological and cardiological active disease. A hallmark of TTS is its association with a preceding stressful event. It may also be connected to a wide variety of diseases, including neurological ones, such as stroke, intracranial bleeding, head trauma, migraine, and seizures. However, up to our knowledge, only few cases of MS-induced TTS were previously described. Whether it is plausible to consider TTS as an uncommon extra-neurological manifestation of MS is still debated, however all the evidence points in that direction, considering the central role of catecholamines in TTS pathogenesis. With this case report the authors hope to encourage research on this field and on the intricate topic of brain-heart connections.

Coeliac disease (CD) is an autoimmune condition with a high prevalence among general population and multisystemic involvement: a more complex scene than a merely gastrointestil disease. Therefore, an early diagnosis and treatment with a gluten-free diet is mainly important to reduce mortality and comorbidities. Together with autoimmune diseases (as Hashimoto thyroiditis, insulin-dependent diabetes mellitus, autoimmune liver disease and connective tissue diseases), also an accelerated progression of atherosclerosis and a higher prevalence of heart disease have been reported in coeliacs. In the present paper we tried to collect from literature the emergent data on the probable relationship between coeliac and cardiovascular disease, focusing on pathophysiological bases of vascular injury. Data and opinions on the development of cardiovascular risk in patients with CD are conflicting. However, the major evidence supports the theory of an increased cardiovascular risk in CD, due to many mechanisms of myocardial injury, such as chronic malabsorption, abnormalities of intestil permeability, and direct immune response against self-proteins. The conclusions that come from these data suggest the utility of a careful cardiovascular follow up in coeliac patients.

Treatment of iron deficiency (ID) in patients with heart failure (HF) has improved symptoms, quality of life, exercise capacity and has reduced hospitalizations in randomized controlled trials (RCTs) and meta-alyses. Intravenous ferric carboxymaltose (FCM) provided convincing results in this field, while oral iron supplementation failed. However, FCM and oral iron were compared to placebo, and a comparison between the two strategies is still lacking. We aimed to fill this gap of knowledge with an indirect comparison between them by means of a network meta-alysis of RCTs. Five studies measuring exercise capacity (i.e. 6-minute walking test) and quality of life (i.e. Kansas City Cardiomyopathy Questionire) were eligible to be included in our review. Given the limitations of a network meta-alysis, our findings support the better efficacy of FCM than oral iron as regards exercise capacity, with a trend towards an improvement in quality of life, suggesting that FCM seems to be strategy of choice to correct ID in HF patients.

Right ventricular dysfunction is a prognostic factor for morbidity and mortality across a broad spectrum of cardiovascular diseases. While the role of the right ventricle in surgical patients has emerged, the prognostic impact of right ventricular dysfunction remains unclear in a large cardiac surgery population. We reviewed the existing literature about the role of right ventricular dysfunction in adults undergoing different kinds of cardiac surgery either present before or developed after surgery itself. Pre- and post-operative right ventricular dysfunction has demonstrated substantial prognostic implications. However, there remains a lack of consensus regarding its definition and diagnostic criteria. The available literature is limited to small-sized studies, underscoring the need for studies with larger populations.

Background Continuous glucose monitoring (CGM) shows in more detail the glycaemic pattern of diabetic subjects and provides several new parameters (“glucometrics”) to assess patients’ glycaemia and consensually guide treatment. A better control of glucose levels might result in improvement of clinical outcome and reduce disease complications. This study aimed to gather an expert consensus on the clinical and prognostic use of CGM in diabetic patients at high cardiovascular risk or with heart disease. Methods A list of 22 statements concerning type of patients who can benefit from CGM, prognostic impact of CGM in diabetic patients with heart disease, CGM use during acute cardiovascular events and educational issues of CGM were developed. Using a two-round Delphi methodology, the survey was distributed online to 42 Italian experts (21 diabetologists and 21 cardiologists) who rated their level of agreement with each statement on a 5-point Likert scale. Consensus was predefined as more than 66% of the panel agreeing/disagreeing with any given statement. Results Forty experts (95%) answered the survey. Every statement achieved a positive consensus. In particular, the panel expressed the feeling that CGM can be prognostically relevant for every diabetic patient (70%) and that is clinically useful also in the management of those with type 2 diabetes not treated with insulin (87.5%). The assessment of time in range (TIR) , glycaemic variability (GV) and hypoglycaemic/hyperglycaemic episodes were considered relevant in the management of diabetic patients with heart disease (92.5% for TIR, 95% for GV, 97.5% for time spent in hypoglycaemia) and can improve the prognosis of those with ischaemic heart disease (100% for hypoglycaemia, 90% for hyperglycaemia) or with heart failure (87.5% for hypoglycaemia, 85% for TIR, 87.5% for GV). The experts retained that CGM can be used and can impact the short- and long-term prognosis during an acute cardiovascular event. Lastly, CGM has a recognized educational role for diabetic subjects. Conclusions According to this Delphi consensus, the clinical and prognostic use of CGM in diabetic patients at high cardiovascular risk is promising and deserves dedicated studies to confirm the experts’ feelings.
