Aims: Despite general agreement on the benefits of the Heart Team approach for patients with cardiac diseases, few data are available on its real impact on the decision-making process. The aim of the study is to define the evolution over time of the level of agreement with the systematic discussion of patients in the Heart Team and to evaluate the adherence to the Heart Team recommendations and the impact of the Heart Team on the clinical outcome of the patients., Methods: In 2015--2016, an experienced cardiac surgeon and a cardiologist independently reviewed clinical data of a series of 100 patients (Group 1, G1) and subsequently for each patient recommended treatment (surgical, percutaneous, hybrid or medical therapy) or further diagnostic investigations. The next day, each case was discussed by the Hospital Heart Team. The Heart Team recommendation, the subsequent treatment received by the patient and the in-hospital outcome were recorded. The same study procedure was repeated in 2017 in a second (G2) and in 2018 in a third (G3) group, both of them including 100 patients., Results: Complete agreement in treatment selection by the cardiac surgeon, cardiologist and the Heart Team was observed in 43% of cases in G1 and in 70% and 68% in G2 and G3, respectively (G1 vs. G2: P  < 0.001, G1 vs. G3: P  = 0.01, G2 vs. G3: P  = 0.30). Agreement was less frequent in patients with a higher risk profile and in patients with aortic valve stenosis. The Heart Team decision was implemented in 95% of cases with a 30-day mortality of 0.67%., Conclusion: Agreement in treatment selection among the cardiac surgeon, cardiologist and Heart Team appears to be low in the initial experience. Subsequently, it seems to steadily increase over time up to a limit, when it reaches a plateau of stable results. Heart Team clinical cases discussion, based on both guidelines and multidisciplinary experience, represents a key step in defining the best patient treatment pathway, potentially improving the decision-making process and clinical results., (Copyright © 2023 Italian Federation of Cardiology - I.F.C.

The term "coronary microvascular dysfunction" (CMD) encompasses several pathogenetic mechanisms resulting in functional and/or structural changes in the coronary microcirculation. CMD often determines angina and myocardial ischemia in a broad spectrum of cardiovascular diseases, including patients with ischemia with non-obstructive coronary arteries or ischemia with obstructive coronary artery disease, infarction with non-obstructive coronary arteries, cardiomyopathies, the Takotsubo syndrome and heart failure, especially heart failure with preserved ejection fraction. In this article, we provide updated evidence regarding the pathophysiological mechanisms underlying CMD across the different cardiovascular diseases, aiming to pave the way for further research and the development of novel strategies for a precision medicine approach., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023.

Obesity is a modifiable cardiovascular risk factor, but adipose tissue (AT) depots in humans are anatomically, histologically, and functionally heterogeneous. For example, visceral AT is a pro-atherogenic secretory AT depot, while subcutaneous AT represents a more classical energy storage depot. Perivascular adipose tissue (PVAT) regulates vascular biology via paracrine cross-talk signals. In this position paper, the state-of-the-art knowledge of various AT depots is reviewed providing a consensus definition of PVAT around the coronary arteries, as the AT surrounding the artery up to a distance from its outer wall equal to the luminal diameter of the artery. Special focus is given to the interactions between PVAT and the vascular wall that render PVAT a potential therapeutic target in cardiovascular diseases. This Clinical Consensus Statement also discusses the role of PVAT as a clinically relevant source of diagnostic and prognostic biomarkers of vascular function, which may guide precision medicine in atherosclerosis, hypertension, heart failure, and other cardiovascular diseases. In this article, its role as a 'biosensor' of vascular inflammation is highlighted with description of recent imaging technologies that visualize PVAT in clinical practice, allowing non-invasive quantification of coronary inflammation and the related residual cardiovascular inflammatory risk, guiding deployment of therapeutic interventions. Finally, the current and future clinical applicability of artificial intelligence and machine learning technologies is reviewed that integrate PVAT information into prognostic models to provide clinically meaningful information in primary and secondary prevention., (© The Author(s) 2023.

The human gut microbiota is the microbial ecosystem in the small and large intestines of humans. It has been naturally preserved and evolved to play an important role in the function of the gastrointestinal tract and the physiology of its host, protecting from pathogen colonization, and participating in vitamin synthesis, the functions of the immune system, as well as glucose homeostasis and lipid metabolism, among others. Mounting evidence from animal and human studies indicates that the composition and metabolic profiles of the gut microbiota are linked to the pathogenesis of cardiovascular disease, particularly arterial hypertension, atherosclerosis, and heart failure. In this review article, we provide an overview of the function of the human gut microbiota, summarize, and critically address the evidence linking compositional and functional alterations of the gut microbiota with atherosclerosis and coronary artery disease and discuss the potential of strategies for therapeutically targeting the gut microbiota through various interventions., Competing Interests: Conflict of interest: This manuscript was handled by Associate Editor Dominik N Müller., (© The Author(s) 2022.

Aims: Low-dose (LD) direct oral anticoagulants (DOACs) in adjunct to antiplatelet therapy, known as dual-pathway inhibition (DPI), have been tested to prevent ischaemic events in patients with cardiovascular disease (CVD). We conducted a systematic review and meta-analysis to determine the overall safety and efficacy of LD DOACs vs placebo on a background of antiplatelet therapy., Methods and Results: All randomized controlled trials (RCTs) comparing LD DOAC (defined as a dosage below the lowest approved for stroke prevention) vs placebo among patients with CVD receiving single or dual antiplatelet therapy (DAPT) in at least 50% of the population and followed for at least 6 months, were included. Incidence rate ratios (IRRs) with 95% confidence intervals (CIs) were used to overcome different follow-up durations across trials. The primary efficacy endpoint was major adverse cardiovascular events (MACE) and the primary safety endpoint major bleeding. A pre-specified subgroup analysis was performed for different DOAC-dose regimens. A total of 49 802 patients from 7 RCTs were included. Low-dose DOACs vs placebo were associated with significant reductions in MACE (IRR 0.85, 95% CI 0.78-0.91, number needed to treat, NNT, 86) and myocardial infarction (IRR 0.86, 95% CI 0.78-0.95, NNT 355) and significant increases of major (IRR 2.05, 95% CI 1.50-2.80, number needed to harm, NNH, 89) or all bleeding (IRR 1.82, 95% CI 1.49-2.22, NNH 23). Cardiovascular death (IRR 0.90, 95% CI 0.79-1.03, NNT 784), intracranial (IRR 1.18, 95% CI 0.71-1.96, NNH 1810), and fatal bleeding (IRR 1.13, 95% CI 0.76-1.69, NNH 3170) did not differ significantly between strategies. Non-significant reductions of all-cause death (IRR 0.90, 95% CI 0.80-1.01, NNT 821) and stroke (IRR 0.73, 95% CI 0.53-1.01, NNT 315) favoured LD DOACs. Meta-regression analyses showed a significant interaction between percentage of DAPT use and increased risk of major bleeding (P = 0.04), intracranial haemorrhage (P = 0.035), and stroke (P = 0.0003). Subgroup analysis of very LD DOAC, defined as ≤1/3 of the lowest approved dose for stroke prevention (i.e. rivaroxaban 2.5 mg twice daily) seemed to mitigate the risk of bleeding without any trade-off in efficacy compared to other LD DOAC regimens., Conclusions: In patients with CVD, LD DOAC vs placebo on a background of antiplatelet therapy, reduced ischaemic events at the expense of increased major and all bleeding, but without significantly increasing intracranial or fatal bleeds, while the reduction of cardiovascular or total mortality and stroke was not statistically significant. A DPI with very LD DOAC (i.e. rivaroxaban 2.5 mg twice daily) appeared particularly advantageous, especially when combined with a single antiplatelet agent and used among patients at high ischaemic and low bleeding risk., Study Registration: This study is registered in PROSPERO (CRD42021232744)., (Published on behalf of the European Society of Cardiology.

Introduction: Multiple Myeloma (MM) is hematological neoplasia originating from plasma cells, which accounts for almost 1% of all oncologic malignancies. The median age of patients at diagnosis is about 65 years old and over. In this age group, cardiovascular (CV) diseases often co-exist, increasing the risk of adverse events related to MM treatment. A comprehensive search on the main educational platforms was performed and high-quality original articles and reviews were included., Areas Covered: Patients affected by MM are at risk for heart failure, uncontrolled systemic hypertension, accelerated ischemic heart disease, arterial/venous thromboembolism, and arrhythmias. These complications may be due to the effects of chemotherapy on the CV system, which may play on preexisting risk factors, and amyloid deposition at cardiac level., Expert Opinion: This review provides an updated overview of the spectrum of CV diseases that may affect MM patients, highlighting possible treatment strategies according to the latest recommendations. Cooperation between onco-hematologist and cardiologist is crucial in managing this population, in particular for adequate risk assessment, early diagnosis of CV complications, and proper treatment.

Background: Recent trials demonstrated the clinical efficacy of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in patients with heart failure (HF), regardless of the presence or absence of type 2 diabetes. These data may allow the use of this innovative drug class in clinical routine for treating these patients., Study Question: We aimed at further clarifying the role of SGLT2i in patients with diagnosis of HF, capitalizing on pooled sample size and heightened power for clinically relevant safety and efficacy outcomes., Data Sources: We conducted a systematic search of PubMed, reference lists of relevant articles, and Medline database from inception until March 1, 2021., Study Design: This meta-analysis was completed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched for randomized trials that evaluated the cardiovascular effects of SGLT2i in patients with HF. Three investigators independently assessed study eligibility, extracted the data, and assessed risk of bias. Hazard ratios and 95% confidence intervals (CIs) were pooled and meta-analyzed using a random-effect model. Numbers needed to treat (NNT) with the relative 95% CIs were also calculated. The primary outcome was a composite of HF hospitalization or an urgent visit for worsening HF and cardiovascular death., Results: Three trials were included in the study. Overall, treatment with SGLT2i was associated with a lower risk of the primary composite outcome [hazard ratios 0.73, 95% CI (0.67-0.80), NNT = 11.3]. Similarly, there was a significantly reduced risk of cardiovascular death, all-cause death, HF hospitalization and need for urgent treatment for HF, and HF hospitalization., Conclusions: Therefore, the available evidence supports the routine use of these drugs as standard-of-care, also given the highly favorable NNTs., Competing Interests: G.

Coronary microvascular dysfunction (CMD) encompasses several pathogenetic mechanisms involving coronary microcirculation and plays a major role in determining myocardial ischemia in patients with angina without obstructive coronary artery disease, as well as in several other conditions, including obstructive coronary artery disease, nonischemic cardiomyopathies, takotsubo syndrome, and heart failure, especially the phenotype associated with preserved ejection fraction. Unfortunately, despite the identified pathophysiological and prognostic role of CMD in several conditions, to date, there is no specific treatment for CMD. Due to the emerging role of CMD as common denominator in different clinical phenotypes, additional research in this area is warranted to provide personalized treatments in this "garden variety" of patients. The purpose of this review is to describe the pathophysiological mechanisms of CMD and its mechanistic and prognostic role across different cardiovascular diseases. We will also discuss diagnostic modalities and the potential therapeutic strategies resulting from recent clinical studies., Competing Interests: Funding Support and Author Disclosures Dr Montone is supported by a Grant for Young Investigators “Ricerca Finalizzata GR-2019-12370197” from the Italian Ministry of Health.

While we continue to wrestle with the immense challenge of implementing equitable access to established evidence-based treatments, substantial gaps remain in our pharmacotherapy armament for common forms of cardiovascular disease including coronary and peripheral arterial disease, heart failure, hypertension, and arrhythmia. We need to continue to invest in the development of new approaches for the discovery, rigorous assessment, and implementation of new therapies. Currently, the time and cost to progress from lead compound/product identification to the clinic, and the success rate in getting there reduces the incentive for industry to invest, despite the enormous burden of disease and potential size of market. There are tremendous opportunities with improved phenotyping of patients currently batched together in syndromic "buckets." Use of advanced imaging and molecular markers may allow stratification of patients in a manner more aligned to biological mechanisms that can, in turn, be targeted by specific approaches developed using high-throughput molecular technologies. Unbiased "omic" approaches enhance the possibility of discovering completely new mechanisms in such groups. Furthermore, advances in drug discovery platforms, and models to study efficacy and toxicity more relevant to the human disease, are valuable. Re-imagining the relationships among discovery, translation, evaluation, and implementation will help reverse the trend away from investment in the cardiovascular space, establishing innovative platforms and approaches across the full spectrum of therapeutic development.

Background: Family history (FH) of cardiovascular disease (CVD) in first degree relatives (FDR) is a major risk factor, especially for premature events. Data are sparse on FH of different manifestations of CVD among FDRs of patients with premature myocardial infarction (MI), chronic stable angina (CSA) or peripheral vascular disease (PVD)., Methods: We obtained FHs from first degree relatives (parents or siblings) of 230 consecutive patients with premature (men < 60 and women < 65 years) CVD, including 79 wth MI, 39 CSA, 51 PVD and 61 blood donors. Among 1225 parents or siblings, 421 had MI, 222 CSA, 261PVD and 321 were among blood donors., Results: FH of MI were 5.6% (18/321) among blood donors, 14.0% (59/421) among patients with premature MI, 14.4% (32/222) CSA, and 8.0% (21/261) PVD. (all p < 0.05). For FH of CSA the corresponding frequencies were 3.7% 5.2%, 11.3%, and 6.9%. (all p < 0.05). For PVD, the corresponding frequencies were 2.1%, 3.4%, 0.9% and 0.7%, respectively. (p = ns)., Conclusions: These data are compatible with the hypothesis that FH of MI, CSA and PVD are significantly different for patients with premature MI or CSA but not PVD., (Copyright © 2021 Elsevier B.V.

Introduction: The association between thrombosis, cancer and inflammation is well-established. Platelets play a major role in atherosclerosis, inflammation and immune response. Furthermore, growing evidence suggests that they are also significantly involved in tumor development and progression so that anti-platelet agents may prevent cancer and improve outcomes in oncological patients. In this review, we aimed at analyzing the relationship between platelets, cardiovascular diseases and cancer. A comprehensive study in the main educational platforms was performed and high-quality original articles and reviews were included., Areas Covered: This review will focus on the role of platelets in cardiovascular disease and in cancer genesis and progression, analyzing their function as immune cells that link inflammation to thrombosis. Finally, it will examine the recent controversies on the use of anti-platelet agents as cancer medications, in particular the already known anti-tumor properties of aspirin, as well as the new perspectives regarding P2Y12 inhibitors., Expert Opinion: Platelet-cancer crosstalk generates a vicious feed-back loop involving tumor cells and secreting molecules that activate platelets, which in turn promote cancer-associated inflammation, proliferation, spreading and immune system evasion. Therefore, platelets inhibition may represent an innovative therapeutical strategy offered to cancer patients, in the perspective of personalized medicine.

Importance: Changes in evidence-based practice and guideline recommendations depend on high-quality randomized clinical trials (RCTs). Commercial device and pharmaceutical manufacturers are frequently involved in the funding, design, conduct, and reporting of trials, the implications of which have not been recently analyzed., Objective: To evaluate the design, outcomes, and reporting of contemporary randomized clinical trials of invasive cardiovascular interventions and their association with the funding source., Design, Setting, and Participants: This cross-sectional study analyzed published RCTs between January 1, 2008, to May 31, 2019. The trials included those involving coronary, vascular and structural interventional cardiology, and vascular and cardiac surgical procedures., Main Outcomes and Measures: We assessed (1) trial characteristics, (2) finding of a statistically significant difference in the primary end point favoring the experimental intervention, (3) reporting of implied treatment advantage in trials without significant differences in primary end point, (4) existence of major discrepancies between registered and published primary outcomes, (5) number of patients whose outcomes would need to switch from a nonevent to an event to convert a significant difference in primary end point to nonsignificant, and (6) association with funding source., Results: Of the 216 RCTs analyzed, 115 (53.2%) reported having commercial sponsorship. Most trials had 80% power to detect an estimated treatment effect of 30%, and 128 trials (59.3%) used composite primary end points. The median (interquartile range [IQR]) sample size was 502 (204-1702) patients, and the median (IQR) follow-up duration was 12 (1.0-14.4) months. Overall, 123 trials (57.0%) reported a statistically significant difference in the primary outcome favoring the experimental intervention; reporting strategies that implied an advantage were identified in 55 (65.5%) of 84 trials that reported nonsignificant differences. Commercial sponsorship was associated with a statistically significantly greater likelihood of favorable outcomes reporting (exponent of regression coefficient β, 2.80; 95% CI, 1.09-7.18; P = .03) and with the reporting of findings that are inconsistent with the trial results. Discrepancies between the registered and published primary outcomes were found in 82 trials (38.0%), without differences in trial sponsorship. A median (IQR) number of 5 (2.8-12.5) patients experiencing a different outcome would have change statistically significant results to nonsignificant. Commercial sponsorship was associated with a greater number of patients (exponent of regression coefficient β, 1.29; 95% CI, 1.00-1.66; P = .04)., Conclusions and Relevance: These results suggest that contemporary RCTs of invasive cardiovascular interventions are relatively small and fragile, have short follow-up, and have limited power to detect large treatment effects. Commercial support appeared to be associated with differences in trial design, results, and reporting.
