Cardio-oncology is an increasingly important field of cardiology that focuses on the detection, monitoring, and treatment of cardiovascular disease (CVD) occurring during and after oncological treatments. The survival rate for childhood cancer patients has dramatically increased thanks to new treatment protocols and cardiovascular (CV) sequelae represent the third most frequent cause of mortality in surviving patients. This study aims to provide a complete and updated review of all the main aspects of cardio-oncology in childhood and to highlight the critical issues.The problem of CV complications in childhood cancer survivors raises the need to make an early diagnosis of cardiotoxicity by the new imaging and laboratory techniques in order to intervene promptly and to implement pharmacological strategies and lifestyle changes to reduce or even to prevent cardiac injury. Furthermore, a stratification of CV risk, also including new predisposing factors such as the presence of some genetic mutations, is of paramount importance before undertaking oncological treatments. Besides, a systematic and personalized planning of long-term follow-up is fundamental to ensure a transition from pediatric to adult hospital and to avoid missed or late diagnosis of cardiomyopathy. We reviewed the main risk factors for cardiotoxicity in children, both traditional and emerging ones: the mechanisms of toxicity of both old and new antineoplastic therapies, the techniques for detecting cardiac damage, and the current evidence regarding pharmacological cardioprotection. At the end, we focused our attention on the existing guidelines and strategies about the long-term follow-up of childhood cancer survivors.

Although real-time 3D echocardiography (RT3DE) has only been introduced in the last decades, its use still needs to be improved since it is a time-consuming and operator-dependent technique and acquiring a good quality data can be difficult. Moreover, the additive value of this important diagnostic tool still needs to be wholly appreciated in clinical practice. This review aims at explaining how, why, and when performing RT3DE is useful in clinical practice.

The growing use of imaging examinations has led to increased detection of spontaneous coronary artery dissection (SCAD) as a non-atherosclerotic cause of acute coronary syndrome (ACS). Since a greater awareness of pathophysiologic mechanisms has relevant implications in clinical practice, we aim to provide an update to current knowledge of SCAD pathophysiology. We discuss the most common conditions associated with SCAD, including predisposing factors and triggers, and focus on potential mechanisms leading to SCAD development. Furthermore, we report the main genetic research findings that have shed further light on SCAD pathophysiology. Finally, we summarize practical considerations in SCAD management based on pathophysiologic insights.

Gut microbiota impacts host health by mediating beneficial physiological processes. However, growing evidence supports the potential role of microbiota in disease development and progression. In this review, we report current knowledge on pathophysiologic processes mediated by gut microbiota that may be implicated in atherosclerosis development and progression. We also summarize findings provided by clinical studies that indicate an association between gut microbiota composition and/or function and atherosclerotic cardiovascular diseases. Finally, we discuss potential strategies to impact gut microbiota composition and/or function in order to reduce the atherosclerotic cardiovascular risk.

In patients with atherosclerotic disease, the occurrence of atherothrombotic events is the main determinant of morbidity and mortality. Growing evidence suggests the involvement of the coagulation pathway in the atherosclerotic process and the benefit of antithrombotic agents, such as direct oral anticoagulants, which interfere with both platelet aggregation and the coagulation cascade. The COMPASS trial has shown that in patients with stable coronary artery disease (CAD) or peripheral artery disease (PAD), low-dose rivaroxaban (2.5 mg twice daily) added to acetylsalicylic acid (ASA) 100 mg reduces major vascular events and mortality, with an increase in major bleeding but not in fatal bleeding or involving a critical organ. The reduction in major cardiovascular events has been confirmed in the overall population with CAD and in both patients with and without a previous percutaneous coronary revascularization, and also in patients with previous coronary bypass surgery. In patients with PAD, the combination of rivaroxaban 2.5 mg twice daily and ASA was found to reduce both major adverse cardiovascular events and major adverse limb events, including major limb amputations. In clinical practice, the use of rivaroxaban 2.5 mg co-administered with ASA has been approved in both patients with CAD and symptomatic PAD at high risk of ischemic events. However, in Italy, the national health system reimbursement is provided only for patients with PAD. In patients treated with rivaroxaban 2.5 mg, assessment and monitoring of bleeding risk is crucial to achieve the maximum clinical benefit.

Geriatric patients are an increasing population and cancer treatment in this population is a challenging and unsolved issue. Ageing is characterized by low-grade inflammation (inflamm-ageing), an important driver for age-related diseases such as cardiovascular diseases and cancer. These chronic conditions share pathophysiological bases, risk factors and may coexist. The burden of comorbidities lowers the threshold for cardiotoxic effects of oncologic treatments. Geriatric assessment is helpful in identifying the peculiar vulnerabilities of this complex population, but a multidisciplinary approach (with oncologists and cardio-oncologists) is needed to improve the appropriateness of care. In this ANMCO position paper, we define the role of cardio-oncologists in the different scenarios of older cancer patients (active cancer, long-term survivors), the importance of geriatric assessment, the unmet needs of survivors and the complexity of comorbidity management.

Direct oral anticoagulants (DOACs) have demonstrated a positive benefit-risk balance compared with vitamin K antagonists in both clinical trials and real-world studies. However, with increased DOAC use, the risk of bleeding should not be underestimated. In clinical practice, the annual rate of DOAC-related major bleeding is between approximately 1.5% and 3.5%. The outcome of major bleeds was similar or better in patients receiving DOACs than in those taking vitamin K antagonists. Due to their short half-lives, supportive measures are sufficient to manage most bleeds in patients receiving DOACs. Anticoagulant reversal should only be considered with life-threatening bleeds or with serious bleeds that fail to respond to usual measures. Effective strategies to reverse the anticoagulant effects of DOACs are now available. Idarucizumab has been approved for dabigatran reversal and andexanet alfa was recently granted approval for the reversal of apixaban or rivaroxaban in patients with life-threatening or uncontrolled bleeding events. Other reversal agents (e.g. ciraparantag for heparins and DOACs) are under development. Non-specific prohemostatic agents (e.g. prothrombin complex concentrate) can counteract the anticoagulant action of DOACs in emergency situations, when specific reversal agents are unavailable. However, specific reversal agents are efficacious and safe and should be preferred when available.

A significant risk of maternal and fetal morbidity and mortality has been shown to be associated with congenital heart disease or heart disease occurring during pregnancy. Given the increasing number of patients with corrected congenital heart disease who reach fertile age and the more and more common advanced maternal age associated with preexisting or intercurrent comorbidities, a higher incidence of cardiac complications in pregnancy has been reported in the last decades. Improvement in maternal and neonatal outcomes is influenced by a multidisciplinary strategy. The purpose of this review is to assess the role of the Pregnancy Heart Team which should ensure careful pre-pregnancy counseling, pregnancy monitoring, and delivery planning for both congenital heart disease and other cardiac or metabolic disorders.

Congenital heart disease (CHD) and cardiomyopathies represent the two most important causes of paediatric heart failure (HF) in developed countries. We made a review of the literature on pathophysiology and clinical presentation of paediatric HF in children with CHD. Two main pathophysiologic models can be identified: the 'over-circulation failure', characterised by signs and symptoms of congestion or hypoperfusion, due respectively to volume or pressure overload, and the 'pump failure'. CONCLUSIONS: The comprehension of the HF pathophysiology in paediatric patients with CHD is of paramount importance for the optimal management and for addressing the best therapeutic choices.

Herein, we describe a 54-year-old patient with a congenital ventricular diverticulum (CVD), referred to our emergency department for presyncope episodes and multiple re-entrant ventricular tachycardias (VT). Significantly, echocardiographic findings were not clear, and the diagnosis was made by cardiac magnetic resonance imaging (CMRI), which showed the presence of an apical accessory cavity connected to the ventricle and contracting synchronously. CMRI allowed the differential diagnosis with other outpouching cardiac defects. The patient underwent a subcutaneous implantable cardioverter defibrillator (S-ICD) implant and was referred for heart transplantation (HT). The diagnosis, treatment, and main findings of the CVD are discussed in this case report.

Patent foramen ovale (PFO) is a common cardiac abnormality with a prevalence of 25% in the general population. PFO has been associated with the paradoxical embolism causing cryptogenic stroke and systemic embolization. Results from clinical trials, meta-analyses, and position papers support percutaneous PFO device closure (PPFOC), especially if interatrial septal aneurysms coexist and in the presence of large shunts in young patients. Remarkably, accurately evaluating patients to refer to the closure strategy is extremely important. However, the selection of patients for PFO closure is still not so clear. The aim of this review is to update and clarify which patients should be considered for closure treatment.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors, dapagliflozin, and empagliflozin, first developed as glucose-lowering agents for the treatment of Type 2 diabetes, have been demonstrated to improve prognosis in patients with heart failure and reduced ejection fraction (HFrEF) regardless of the presence of diabetes. Since these drugs have only recently been included among the four pillars of HFrEF treatment, cardiologists are still unfamiliar with their use in this setting. This article provides an up-to-date practical guide for the initiation and monitoring of patients treated with SGLT2 inhibitors.

Cancer patients have an increased risk of cardiovascular disease and, notably, a significant prevalence of acute coronary syndrome (ACS). It has been shown that an elevated presence of cardiovascular risk factors in this setting leads to an interaction between these two conditions, influencing their therapeutic strategies and contributing to higher mortality. Nonetheless, cancer patients have generally not been evaluated in ACS trials, so that the treatment in these cases is still not fully known. We reviewed the current literature and discussed the best management for these very high-risk patients. The treatment strategy must be tailored based on the cancer type and stage, balancing thrombotic and bleeding risks. When the prognosis is longer than six months, especially if a clinical instability coexists, patients with ACS and cancer should be referred for percutaneous coronary intervention (PCI) as soon as possible. Moreover, an invasive strategy should be preferred in STEMI patients as well as in NSTEMI patients who are considered as high risk. On the contrary, in clinically stable NSTEMI patients, a conservative non-invasive strategy could be adopted, especially in cases of a poor life expectancy and/or of high risk of bleeding. Drug-Eluting-Stents (DES) should be the first choice if an invasive strategy is adopted. Conservative therapy could instead be considered in cancer patients with more stable CAD at an increased risk of major bleeding complications. However, the duration of dual antiplatelet therapy (DAPT) with aspirin and clopidogrel is recommended, but it should be as short as possible, whereas triple antithrombotic therapy is non-advised because it significantly increases the risk of bleeding. ACS management among cancer patients should be based on an accurate evaluation of the risk of thrombosis and bleeding. Future studies focused on choosing optimal strategies in tumor patients with ACS should be performed to treat this subset of patients better.

This study aims to establish the incidence of atrial fibrillation (AF) in breast cancer (BC) patients, focusing on staging and anti-cancer treatment. A meta-analysis was conducted to investigate the incidence of AF in BC patients and compare this incidence to other cancers. Furthermore, we evaluated the occurrence of AF as an adverse effect of biological therapies vs. non-biological therapies vs. biological therapies + non-biological therapies in BC. Finally, we compared the incidence of AF in early BC and metastatic BC. Thirty studies were included. Twenty-two studies focused on BC, encompassing 166,271 patients. In the BC group, 2.7% of patients developed AF, while in the “all cancer” group, 5.8% of patients developed AF. In addition, there was no difference between different types of therapies (p = 0.61) and between early and metastatic BC (p = 0.57). The type of anti-cancer therapy and the staging of BC does not influence AF’s occurrence in this neoplastic disease.

Antithrombotic drugs, which include antiplatelets and anticoagulants, are effective in prevention and treatment of many cardiovascular disorders such as acute coronary syndromes, stroke, and venous thromboembolism and are among the drugs most commonly prescribed worldwide. The advent of direct oral anticoagulants, which are safer alternatives to vitamin K antagonists and do not require laboratory monitoring, has revolutionized the treatment of nonvalvular atrial fibrillation and venous thromboembolism. The combination of oral anticoagulant and antiplatelet therapy is required in many conditions of great clinical impact such as the coexistence of atrial fibrillation and coronary artery disease, with indication to percutaneous coronary intervention. However, strategies that combine anticoagulant and antiplatelet therapies lead to a significant increase in bleeding rates and it is crucial to find the right combination in the single patient in order to optimize the ischemic and bleeding risk. The aim of this review is to explore the evidence and controversies regarding the optimal combination of anticoagulant and antiplatelet therapy through the consideration of past dogmas and new perspectives from recent clinical trials and to propose a tailored therapeutic approach, according to specific clinical scenarios and individual patient characteristics. In particular, we separately explored the clinical settings of stable and acute coronary syndromes and percutaneous revascularization in patients with atrial fibrillation.

BACKGROUND Atrial fibrillation is common in the setting of acute coronary syndromes (ACS) although its impact on ACS remains controversial. AIM To describe in-hospital management of patients with atrial fibrillation and ACS evaluating the impact of atrial fibrillation on in-hospital and mid-term outcome. METHODS We analysed the data of two prospective multicentre nationwide registries (IN-ACS Outcome and MANTRA) to assess clinical characteristics, management, and outcomes of patients with ACS and atrial fibrillation. Study outcomes included death from any cause and a composite end-point of death/re-infarction/stroke/major bleeding within index admission and 6 months' follow-up. RESULTS Out of 12 288 ACS patients, 1236 (10.1%) had atrial fibrillation at admission or developed it during hospitalization. Atrial fibrillation patients were older, more often female, and had higher burden of comorbidities. In-hospital mortality was higher among atrial fibrillation patients (8.7 vs. 2.4%, P

The favorable effects of physical activity on the cardiovascular system have been well described in scientific literature. Physical activity reduces cardiovascular morbidity and mortality in both healthy subjects and in patients with cardiovascular disease. However, different intensity levels of physical activity have a different impact on the cardiovascular system. Some data support the hypothesis of a "physical activity paradox": repetitive exposure to vigorous physical activity may induce biological effects that counteract the benefits of moderate intensity levels of physical activity. In this review, we report the main effects of acute and chronic physical activity on the cardiovascular system and we summarize the biochemical mechanisms that may explain these effects.

The COVID-19 pandemic and its impact on patients with cancer and cardiovascular disease have confirmed the particular vulnerability of this population. Indeed, not only a higher risk of contracting the infection has been reported, but also an increased occurrence of a more severe course and unfavorable outcome. Beyond the direct consequences of COVID-19, the pandemic has an enormous impact on global health systems. Screening programs and non-urgent tests have been postponed; clinical trials have suffered a setback. Similarly, in the area of cardiology care, a significant decline in ST-elevation myocardial infarction accesses and an increase in cases of late presenting heart attacks with increased mortality and complication rates have been reported. Health care systems must therefore get ready to tackle the "rebound effect" that will likely show a relative increase in the short and medium term incidence of diseases such as heart failure, myocardial infarction, arrhythmias and cardio- and cerebrovascular complications. Scientific societies are taking action to provide general guidance and recommendations aimed at mitigating the unfavorable outcomes of this pandemic emergency. Cardio-oncology, as an emerging discipline, is more flexible in modulating care pathways and represents a beacon of innovation in the development of multi-specialty patient management. In the era of the COVID-19 pandemic, cardio-oncology has rapidly modified its clinical care pathways and implemented flexible monitoring protocols that include targeted use of cardiac imaging, increased use of biomarkers, and telemedicine systems. The goal of these strategic adjustments is to minimize the risk of infection for providers and patients while maintaining standards of care for the treatment of oncologic and cardiovascular diseases. The aim of this position paper is to evaluate the impact of the COVID-19 pandemic on the management of cardio-oncologic patients with the-state-of-the-art knowledge about SARS-CoV-2 and COVID-19 in order to optimize medical strategies during and after the pandemic.

Background and aim. Cancer and atrial fibrillation (AF) may be associated, and anticoagulation, either with vitamin K antagonists (VKAs) or direct oral anticoagulants (DOACs), is necessary to prevent thromboembolic events by reducing the risk of bleeding. The log incidence rate ratio (IRR) and 95% confidence interval were used as index statistics. Higgin’s I2 test was adopted to assess statistical inconsistencies by considering interstudy variations, defined by values ranging from 0 to 100%. I2 values of less than 40% are associated with very low heterogeneity among the studies; values between 40% and 75% indicate moderate heterogeneity, and those greater than 75% suggest severe heterogeneity. The aim of this meta-analysis was to compare the safety and efficacy of VKAs and DOACs in oncologic patients with AF. Methods. A meta-analysis was conducted comparing VKAs to DOACs in terms of thromboembolic events and bleeding. A meta-regression was conducted to investigate the differences in efficacy and safety between four different DOACs. Moreover, a sub-analysis on active-cancer-only patients was conducted. Results. A total of eight papers were included. The log incidence rate ratio (IRR) for thromboembolic events between the two groups was −0.69 (p < 0.005). The meta-regression did not reveal significant differences between the types of DOACs (p > 0.9). The Log IRR was −0.38 (p = 0.008) for ischemic stroke, −0.43 (p = 0.02) for myocardial infarction, −0.39 (p = 0.45) for arterial embolism, and −1.04 (p = 0.003) for venous thromboembolism. The log IRR for bleeding events was −0.43 (p < 0.005), and the meta-regression revealed no statistical difference (p = 0.7). The log IRR of hemorrhagic stroke, major bleeding, and clinically relevant non-major bleeding between the VKA and DOAC groups was −0.51 (p < 0.0001), −0.45 (p = 0.03), and 0.0045 (p = 0.97), respectively. Similar results were found in active-cancer patients for all the endpoints except for clinically-relevant non-major bleedings. Conclusions. DOACs showed better efficacy and safety outcomes than VKAs. No difference was found between types of DOACs.

The COVID-19 pandemic and its impact on patients with cancer and cardiovascular disease have confirmed the particular vulnerability of these populations.

What is the central question of this study? Visceral ischaemia is one of the most feared complications during use of an intra-aortic balloon pump. Using an animal model, we measured the flows at the abdominal level directly and examined flow patterns to enable investigation of flow patterns during the use of the intra-aortic balloon pump. What is the main finding and its importance? We show that there is a significant balloon-related reduction in superior mesenteric flow in both early and mid-diastole.A number of previous studies have shown that blood flow in the visceral arteries is altered during intra-aortic balloon pump (IABP) treatment. We used a porcine model to analyse the pattern of blood flow into the visceral arteries during IABP use. For this purpose, we measured the superior mesenteric, right renal and left renal flows before and during IABP support, using surgically placed flowmeters surrounding these visceral arteries. The superior mesenteric flow significantly decreased in early diastole (P 0.001) and in mid-diastole (P = 0.003 versus early diastole), whereas in late diastole it increased again (P 0.001 versus mid-diastole). During systole, the flow was not significantly increased compared with late diastole (P = 0.51), but it was significantly lower than at baseline (both P 0.001). Flows did not differ between right and left kidneys. Perfusion of either kidney did not change significantly in early diastole (P 0.05), whereas it decreased significantly in mid-diastole (P 0.001), rising dramatically in late diastole (P 0.001) and with an additional slight increase in systole (P = 0.054). This study provides important insights into abdominal flows during intra-aortic pump counterpulsation. Furthermore, it supports the need to rethink the balloon design to avoid visceral ischaemia during circulatory assistance.

The combination of oral anticoagulants (OAC) and dual antiplatelet therapy (DAPT) is the mainstay for the treatment of patients with atrial fibrillation (AF) presenting with acute coronary syndrome (ACS) and/or undergoing PCI. However, this treatment leads to a significant increase in risk of bleeding. In most cases, according to the most recent guidelines, triple antithrombotic therapy (TAT) consisting of OAC and DAPT, typically aspirin and clopidogrel, should be limited to one week after ACS and/or PCI (default strategy). On the other hand, in patients with a high ischemic risk (i.e., stent thrombosis) and without increased risk of bleeding, TAT should be continued for up to one month. Direct oral anticoagulants (DOAC) in triple or dual antithrombotic therapy (OAC and P2Y12 inhibitor) should be favored over vitamin K antagonists (VKA) because of their favorable risk/benefit profile. The choice of the duration of TAT (one week or one month) depends on a case-by-case evaluation of a whole series of hemorrhagic or ischemic risk factors for each patient. Likewise, the specific DOAC treatment should be selected according to the clinical characteristics of each patient. We propose a series of paradigmatic clinical cases to illustrate the decision-making work-up in clinical practice.

The extent and quality of the involvement of cardiology units in health programs delivered by Italian centers for heart transplantation (HTx) have not been investigated previously.The Italian Association of Hospital Cardiologists (ANMCO) and the Italian Society for Organ Transplantation (SITO) developed and delivered a nationwide survey to the Directors of the Italian centers for HTx to investigate the extent to which cardiology units contribute to HTx programs. The survey investigated: (i) the organization of the centers and institutional frame under which cardiology units contributed to HTx programs; (ii) the volumes of procedures and clinical services delivered by cardiology units to HTx centers for listing patients, following those waiting for HTx, managing acute heart failure, selecting and allocating organs to recipients, following and managing organ rejection after HTx.Of the 14 Italian centers involved, 13 provided full responses to the survey. Between 2017-2019, on average, 46% of the respondents performed up to 15 HTx/year, and additional 46% performed between 16 and 30 HTx/year. Of the respondents, 62% were included in a department of cardiac Surgery which did not include a cardiology unit; furthermore, 54% declared not to be included in a formal network for heart failure management. Cardiology units were the source for referrals of candidates to HTx in 85% cases. Of the respondents, 15% declared to be able to provide cardiological services thorough intra-center multidisciplinary team including cardiologists, whereas cardiological services were outsourced in 61% of the respondents. The clinical follow-up of patients waiting for HTx was performed directly by surgeons in 38% of the respondents. Worsening heart failure was managed directly by the HTx center in 33% of the cases using dedicated beds. Post-HTx follow-up, including endomyocardial biopsy, involved external cardiology units in less than 25% of the centers.The ANMCO-SITO survey shows that in Italy a very wide variability exists in terms of organization of HTx centers and their relationships with cardiology units for delivering specific cardiological services and procedures. In large majority, patient referral to HTx centers is mediated by cardiology units, whereas HTx was rarely included in a structured cardiological network for heart failure management.

Venous thromboembolism (VTE), including pulmonary embolism and deep venous thrombosis, either symptomatic or incidental, is a common complication in the history of cancer disease. The risk of VTE is 4-7-fold higher in oncology patients, and it represents the second leading cause of death, after cancer itself. In cancer patients, compared with the general population, VTE therapy is associated with higher rates of recurrent thrombosis and/or major bleeding. The need for treatment of VTE in patients with cancer is a challenge for the clinician because of the multiplicity of types of cancer, the disease stage and the imbricated cancer treatment. Historically, in cancer patients, low molecular weight heparins have been preferred for treatment of VTE. More recently, in large randomized clinical trials, direct oral anticoagulants (DOACs) demonstrated to reduce the risk of VTE. However, in the "real life", uncertainties remain on the use of DOACs, especially for the bleeding risk in patients with gastrointestinal cancers and the potential drug-to-drug interactions with specific anticancer therapies.In cancer patients, atrial fibrillation can arise as a perioperative complication or for the side effect of some chemotherapy agents, as well as a consequence of some associated risk factors, including cancer itself. The current clinical scores for predicting thrombotic events (CHA2DS2-VASc) or for predicting bleeding (HAS-BLED), used to guide antithrombotic therapy in the general population, have not yet been validated in cancer patients. Encouraging data for DOAC prescription in patients with atrial fibrillation and cancer are emerging: recent post-hoc analysis showed safety and efficacy of DOACs for the prevention of embolic events compared to warfarin in cancer patients. Currently, anticoagulant therapy of cancer patients should be individualized with multidisciplinary follow-up and frequent reassessment. This consensus document represents an advanced state of the art on the subject and provides useful notes on clinical practice.

Recreational drug use may cause coronary artery disease through several mechanisms. An increasing number of young patients with drug-related acute coronary syndrome have been reported over recent years. The present position statement reports the most recent epidemiological data on acute coronary syndrome in the setting of drug abuse, describes the main pathophysiological mechanisms underlying coronary artery disease and acute events in these patients, and provides practical recommendations on management and an overview of prognosis.

The world's population is ageing; however, the prolonged life expectancy is barely associated with an increase of healthy aging, and an important part of this demographic shift is a rising susceptibility to development and progressive accumulation of multiple chronic illness, challenging healthcare systems. Aging, therefore, represents the major risk factor for multimorbidity, a milestone for progressive loss of resilience and age-related multisystem homeostatic dysregulation. Cardiovascular risk factors, time and comorbidities play a vicious role in the development of heart disease. Among the other comorbidities, age itself is one of the most important risk factors for the development of cardiovascular disease and the prevalence and incidence of cardiovascular disease in the elderly are significantly increased. Elderly subjects, particularly when frail and with comorbidities, however, are scarcely represented in primary and secondary prevention trial aimed to treat hypercholesterolemia, diabetes mellitus and arterial hypertension. In particular, concerns exist about whether treatment should more or less intensive according to tolerability and risk of interactions; as well as there is uncertainty about therapeutic targets at different ages.This article reviews the relationship between ageing and cardiovascular disease, focusing on several issues regarding cardiovascular prevention in the elderly.

Atrial fibrillation (AF) is the most common arrhythmia, increasing with age and comorbidities. Obstructive sleep apnea (OSA) is a chronic sleep disorder more common in older men. It has been shown that OSA is linked to AF. Nonetheless, the prevalence of OSA in patients with AF remains unknown because OSA is significantly underdiagnosed. This review, including 54,271 patients, carried out a meta-analysis to investigate the association between OSA and AF. We also performed a meta-regression to explore cofactors influencing this correlation. A strong link was found between these two disorders. The incidence of AF is 88% higher in patients with OSA. Age and hypertension independently strengthened this association, indicating that OSA treatment could help reduce AF recurrence. Further research is needed to confirm these findings. Atrial Fibrillation (AF) is the most common arrhythmia, increasing with age and comorbidities. Obstructive sleep apnea (OSA) is a regulatory respiratory disorder of partial or complete collapse of the upper airways during sleep leading to recurrent pauses in breathing. OSA is more common in older men. Evidence exists that OSA is linked to AF. Nonetheless, the prevalence of OSA in patients with AF remains unknown because OSA is underdiagnosed. In order to investigate the incidence of AF in OSA patients, we carried out a meta-analysis including 20 scientific studies with a total of 54,271 subjects. AF was present in 4801 patients of whom 2203 (45.9%) had OSA and 2598 (54.1%) did not. Of a total of 21,074 patients with OSA, 2203 (10.5%) had AF and 18,871 (89.5%) did not. The incidence of AF was 88% higher in patients with OSA. We performed a meta-regression to explore interacting factors potentially influencing the occurrence of AF in OSA. Older age and hypertension independently strengthened this association. The clinical significance of our results is that patients with OSA should be referred early to the cardiologist. Further research is needed for the definition of the mechanisms of association between AF and OSA.

Cardiovascular diseases (CVD) have a lower prevalence in women than men; although, a higher mortality rate and a poorer prognosis are more common in women. However, there is a misperception of CVD female risk since women have commonly been considered more protected so that the real threat is vastly underestimated. Consequently, female patients are more likely to be treated less aggressively, and a lower rate of diagnostic and interventional procedures is performed in women than in men. In addition, there are substantial sex differences in CVD, so different strategies are needed. This review aims to evaluate the main gender-specific approaches in CVD.

Even though vitamin K antagonists (VKAs) have been employed for >50 years, there is still some uncertainty about the best strategy to reverse anticoagulation due to VKAs in cases of major bleeding. Furthermore, there is also scarce evidence about the most appropriate way to treat serious bleeding associated with non-vitamin K antagonist oral anticoagulants. This review analyses the main advantages and disadvantages of the various forthcoming therapeutic options to restore a normal coagulation status in anticoagulated patients with ongoing serious bleeding. It discusses the role of fresh frozen plasma, prothrombin complex concentrates and recombinant factor VII activated. Moreover, we report updated evidence on antidotes currently available or in development. Finally, this article proposes a comprehensive algorithm that summarizes major bleeding management during treatment with oral anticoagulants.

In the last decade, the introduction of non-vitamin K antagonist oral anticoagulants (NOACs) in clinical practice has changed the therapeutic landscape in the prevention of thromboembolic events. Although NOACs compared to vitamin K antagonists (VKAs) have demonstrated a similar or slightly lower rate of major bleeding and a lower rate of intracranial or fatal bleeding, hemorrhaging still represents the main adverse effect of anticoagulant treatment. This review reports data on the rates of major bleeding with old and new oral anticoagulants. It analyses laboratory tests that can be used to assess the intensity of anticoagulation in patients treated with oral anticoagulants and discusses general measures to implement in managing major bleeding.

The therapeutic dilemma between rhythm and rate control in the management of atrial fibrillation (AF) is still unresolved and electrical or pharmacological cardioversion (CV) frequently represents a useful strategy. The most recent guidelines recommend anticoagulation according to individual thromboembolic risk. Vitamin K antagonists (VKAs) have been routinely used to prevent thromboembolic events. Non-vitamin K antagonist oral anticoagulants (NOACs) represent a significant advance due to their more predictable therapeutic effect and more favorable hemorrhagic risk profile. In hemodynamically unstable patients, an emergency electrical cardioversion (ECV) must be performed. In this situation, intravenous heparin or low molecular weight heparin (LMWH) should be administered before CV. In patients with AF occurring within less than 48 h, synchronized direct ECV should be the elective procedure, as it restores sinus rhythm quicker and more successfully than pharmacological cardioversion (PCV) and is associated with shorter length of hospitalization. Patients with acute onset AF were traditionally considered at lower risk of thromboembolic events due to the shorter time for atrial thrombus formation. In patients with hemodynamic stability and AF for more than 48 h, an ECV should be planned after at least 3 weeks of anticoagulation therapy. Alternatively, transesophageal echocardiography (TEE) to rule out left atrial appendage thrombus (LAAT) should be performed, followed by ECV and anticoagulation for at least 4 weeks. Theoretically, the standardized use of TEE before CV allows a better stratification of thromboembolic risk, although data available to date are not univocal.

Aim: We evaluated the influence of intra-aortic balloon size and volume on mesenteric and renal flows. Methods: Thirty healthy swine underwent 120-minute ligation of the left anterior descending coronary artery followed by 6 hours of reperfusion. Then, they were randomly assigned to the following five groups of animals, with six animals in each group: no intra-aortic balloon pump (IABP), a short 35-mL IABP, a short 40-mL IABP, a long 35-mL IABP and a long 40-mL IABP. Superior mesenteric artery (SMA) and renal flows were measured at baseline (t0), at 2-hour ischemia (t1) and every hour thereafter until 6 hours of reperfusion (from tR1 to tR6). Results: SMA flows increased significantly at tR1 only in the two short IABP groups (p0.05). Renal flows appeared to be influenced by balloon length, but not by volume. Indeed, flows in the renal arteries rose during IABP treatment; the increase was significantly higher in the short balloon groups and throughout the whole reperfusion (all, pConclusions: Changes in visceral perfusion during IABP assistance were significantly related to balloon length, but not to its volume. This could be relevant for the evolution of balloon engineering design in order to reduce the incidence of mesenteric ischemia following IABP. Further research is necessary to confirm these findings.
