RESUMO

The COVID-19 pandemic represents an unprecedented event that has brought deep changes in hospital facilities with reshaping of the health system organization, revealing inadequacies of current hospital and local health systems. When the COVID-19 emergency will end, further evaluation of the national health system, new organization of acute wards, and a further evolution of the entire health system will be needed to improve care during the chronic phase of disease. Therefore, new standards for healthcare personnel, more efficient organization of hospital facilities for patients with acute illnesses, improvement of technological approaches, and better integration between hospital and territorial services should be pursued. With experience derived from the COVID-19 pandemic,new models, paradigms, interventional approaches, values and priorities should be suggested and implemented.

RESUMO

Atherosclerosis often affects the coronary arterial tree. Frequently the disease does not translate in significant narrowing of the vessels, thus determining only a non-obstructive disease. This condition that is described as non-obstructive coronary artery disease (NobsCAD) should be distinguished from the absence of disease (i.e. smooth coronary arteries) as it carries a specific prognostic value. The detection and reporting of NobsCAD should prompt preventive measures that can be individualized upon the degree of the underlying burden of disease. The accompanying clinical condition, the other cardiovascular risk factors present, and the description of the severity and extent of NobsCAD should provide the framework for an individualized treatment that should also consider the best available scientific evidence and guidelines. The description of NobsCAD represents important information to be collected whenever a coronary angiogram (both invasive and non-invasive) is performed. Treating the patient according to the presence and extent of NobsCAD offers prognostic benefits well beyond those offered by considering only the traditional cardiovascular risk factors. In order to reach this goal, NobsCAD should not be confused with the absence of coronary atherosclerosis or even ignored when detected as if it was a trivial information to provide.

RESUMO

The European Society of Cardiology guidelines on non-ST-elevation acute coronary syndromes suggest different temporal strategies for the angiographic study depending on the risk profile. The scientific evidence underlying the guideline recommendations and the critical issues currently existing in Italy, that often do not allow either an extended strategy of revascularization within 24 h or the application of the principle of the same day transfer from a spoke to a hub centre, are analysed. The position paper focuses, in particular, on the subgroup of patients with a defined diagnosis of non-ST-elevation myocardial infarction by proposing a timing of coronary angiography/revascularization that takes into account the available scientific evidence and the organizational possibilities of a considerable part of national cardiology services.

RESUMO

The COVID-19 pandemic has become a global health emergency. In Italy, the number of people infected by SARS-COVID-2 is rapidly increasing and what emerges from the current data is that the majority do not present any symptoms or only minor flu-like symptoms. In about 20% of the patients, the disease progresses towards more complex forms (interstitial pneumonia to acute respiratory distress and multiple organ failure) with the need of hospitalization in CICU and advanced ventilator assistance. The transmission of the virus occurs very easily from the symptomatic patient s droplets from coughing and sneezing and from direct contact with persons or surfaces. In a patient presenting with ST elevation (STEMI) myocardial infarction or STEMI-like, if positive to COVID-19, the reperfusion therapeutic strategy depends on the local organization and on the possibility to access without delay a PCI COVID Center, on the basis, obviously, of the risk/benefit assessment of the individual case. However, we advise to try pursuing, in the first instance, the mechanical revascularization strategy, according to the available local possibilities.

RESUMO

The aim of this document is the management and organization of patients in need of urgent access to electrophysiology (EP) and pacing procedures during the COVID-19 emergency. Specifically, non-deferrable procedures or irreplaceable with a drug therapy prior to the resolution of the COVID-19 virus emergency [pacemaker (PM) implant/replacement/urgent defibrillator (implantable cardioverter-defibrillator, ICD) or arrhythmic storm or other indication of non-deferrable ablation]. The pacing and electrophysiological procedures urgent as they may be, less and less frequently represent situations of emergency, therefore for almost all cases, it is possible to perform a swab test to determine the positivity to COVID-19 of the patient. In cases where this is not possible, due to situations of emergency, the recommendations and procedures we have indicated are advisable, if not mandatory, in order to avoid the spreading of the virus to healthcare personnel and other patients.

RESUMO

At the end of 2019 a new Coronavirus appeared in China and, from there, it spread to the rest of the world. On 24th May, 2020, the confirmed cases in the world were more than 5 million and the deaths almost 350.000. At the end of May, Italy reported more than 27.000 cases among healthcare professionals and 163 deaths among physicians. The National Health Systems from almost all over the world, including Italy's, were unprepared for this pandemic, and this generated important consequences of organizational nature. All elective and urgent specialized activities were completely reorganized, and many hospital units were partially or completely converted to the care of the COVID-19 patients. A significant reduction in hospital admissions for acute heart disease were recorded during the SARS-CoV-2 pandemic and, in order to gradually resume hospital activities, the Italian National Phase 2 Plan for the partial recovery of activities, must necessarily be associated with a Phase 2 Health Plan. In regards to the cardiac outpatient activities we need to identify short term goals, i.e. reschedule the suspended outpatient activities, revise the waiting lists, review the 'timings' of the bookings. This will reduce the number of available examinations compared to the pre-Covid-19 era. The GP's collaboration could represent an important resource, a structured telephone follow-up plan is advisable with the nursing staff's involvement. It is equally important to set medium-long term goals, the pandemic could be an appropriate moment for making a virtue of necessity. It is time to reason on prescriptive appropriateness, telemedicine implementation intended as integration to the traditional management. It is time to restructure the cardiological units related to the issue of structural adjustment to the needs for functional isolation. Moreover, the creation of 'grey zones' with multidisciplinary management according to the intensity of care levels seems to be necessary as well as the identification of Covid dedicated cardiologies. Finally, the pandemic could represent the opportunity for a permanent renovation of the cardiological and territorial medicine activities.

RESUMO

Infections by SARS CoV2 - COVID-19 became in a short time a worldwide health emergency. The present SARS-CoV-2 pandemic induced in a short time, an unprecedented impact on public health and on the pre-existing care pathways. In order to appropriately address this epidemiological emergency, urgent solutions were needed, such as remodelling or stopping hospitalization and deferrable clinical activities to avoid spreading the SARS-CoV-2 infection. After the first emergency lockdown phase, care pathways must guarantee healthcare to patients and preserve the safety of the healthcare personnel and of all the other subjects that refer to the cardiological surgeries. Rigorous prescriptive appropriateness of the requested exams with consequent reduction of unnecessary examinations is an essential requirement to preserve prioritized diagnostic and care pathways to patients in need, minimizing the risks connected to the SARS-CoV-2 contagion in hospitals. Telemedicine services represent a valid answer to cardiovascular disease patients' need for care and assistance, including those in quarantine and voluntary isolation. These services successfully contribute to fight the spread of the virus guaranteeing at the same time therapy and support through remote services that must therefore be considered a resource to be implemented and enhanced. This document has to be used by the healthcare personnel working in hospitals and in district offices, if applicable, and aims at managing patients, in complete safety and considered not suspect/not probable ('not at risk') of SARS-CoV-2 infection, eligible for diagnostic activity and subsequent therapy in outpatient surgeries. In particular, this document provides indications for patient evaluation to prevent COVID-19 exposure, gives general indications on managing appointments and waiting rooms, on how to strictly adhere to environmental safety measures, on the proper use of Individual Protective Equipment (IPE). It also provides specific indications for outpatient service procedures, like electrocardiogram, cardiologic examination, cardiologic checkup, Dynamic Holter Electrocardiogram, Transthoracic Echocardiography, Echo Stress, Transoesophageal Echocardiography, Bike Ergometer stress test, Ergospirometry, Outpatient Checkup of implantable electronic cardiac devices.

RESUMO

Infections by SARS CoV2 - COVID-19 have become in a short time a worldwide health emergency. Due to cardiovascular implications of COVID-19 and to very frequent previous cardiovascular disorders of COVID-19 patients, it is presently crucial that Cardiologists are fully aware of COVID-19 related epidemiological, pathophysiological and therapeutic problems, in order to manage at best the present emergency by appropriate protocols developed on the basis of the competences acquired and shared on the field. The aim of this document is to propose algorithms for the management of cardiovascular diseases during COVID-19 emergency with the objective of providing patients with optimal care, minimizing contagion risk and appropriately managing personal protective equipment.

RESUMO

Acute clinical manifestations of COVID-19 are generally less severe in childhood, however a proportion of them can develop a severe systemic hyperinflammatory syndrome after SARS-CoV-2 infection, known as the multisystem inflammatory syndrome (multisystem inflammatory syndrome in children, MIS-C). Cardiovascular manifestations in MIS-C are frequent (34-82%), including myocardial dysfunction, coronary artery dilation or aneurysms, arrhythmias, conduction abnormalities, pericarditis and valvulitis. The most affected cases can develop cardiogenic shock needing intensive care unit admission, inotropic support and sometimes even mechanical circulatory support. The elevation of myocardial necrosis markers, the frequently transient left ventricular systolic dysfunction and the presence of changes on magnetic resonance imaging, support the hypothesis of an immune-mediated post-viral pathogenesis similar to myocarditis. Although MIS-C shows excellent short-term survival, further studies are needed to demonstrate complete reversibility of residual subclinical heart damage.

RESUMO

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.

RESUMO

Heart failure is a complex clinical syndrome with a severe prognosis, despite therapeutic progress. The management of the advanced stages of the syndrome is particularly complex in patients who are referred to palliative care as well as in those who are candidates for cardiac replacement therapy. For the latter group, a prompt recognition of the transition to the advanced stage as well as an early referral to the centers for cardiac replacement therapy are essential elements to ensure that patients follow the most appropriate diagnostic-therapeutic pathway. The aim of this document is to focus on the main diagnostic and therapeutic aspects related to the advanced stages of heart failure and, in particular, on the management of patients who are candidates for cardiac replacement therapy.

RESUMO

The progressive shifting in adult patients with congenital heart disease (ACHD) epidemiology with aging and superimposed acquired cardiac pathology on top of complex congenital heart defects is leading to an increase of hospitalizations for heart failure (HF), which nowadays represents one of the main causes of death in this patient population. Although there is a theoretical evidence to support the use of conventional drugs indicated for the general population with HF, randomized controlled trials do often exclude ACHD patients. Anatomical and physiological heterogeneity makes it difficult to define the role of cardiac resynchronization, and indications are less established. Timing of assessment for heart transplantation is challenging and referral often occurs too late. The present review wants to offer a summary of current therapeutic strategies and discuss future perspectives for ACHD-related HF treatment.

RESUMO

The central role of high low-density lipoprotein cholesterol levels in atherosclerotic cardiovascular disease has led to research focused on lipid-lowering agents for cardiovascular risk reduction. Bempedoic acid is an emerging treatment for hypercholesterolemia that has recently been approved for marketing in the United States and Europe. This review focuses on its mechanism of action and summarizes the main preclinical study findings. Furthermore, we report the clinical evidence supporting and guiding its use in hypercholesterolemia management.

RESUMO

Bloodstream cholesterol is a central contributor to atherosclerotic cardiovascular diseases. For several decades, low-density lipoprotein cholesterol (LDL-C) has been the main biomarker for the prediction of cardiovascular events and therapeutic target of lipid-lowering treatments. More recently, several findings have supported the greater reliability of non-high-density lipoprotein cholesterol (non-HDL-C) as a predictive factor and possible therapeutic target in refining antiatherogenic treatments, especially among patients with lower LDL-C and higher triglyceride values. This article discusses the limits of current standard methods for assessing LDL-C levels and emphasizes the persistent residual cardiovascular risk in patients treated with lipid-lowering agents on the basis of recommended LDL-C targets. It highlights that patients with controlled LDL-C and non-targeted non-HDL-C have a higher cardiovascular risk. The article focuses on the role of non-HDL-C as a better predictor of atherosclerotic disease as compared with LDL-C and as a therapeutic target. Finally, this article includes an executive summary aimed at refining preventive approaches in atherosclerotic cardiovascular disease.

RESUMO

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.

RESUMO

The complexity of cardiovascular diseases has led to an extensive use of technological instruments and the development of multimodality imaging. This extensive use of different cardiovascular imaging tests in the same patient has increased costs and waiting times.The concept of appropriateness has changed over time. Appropriateness criteria address the need for specific cardiovascular imaging tests in well-defined clinical scenarios, and define the kind of cardiovascular imaging that is appropriated for each clinical scenario in different stages of the disease. The concept of appropriateness criteria has replaced the old idea of appropriate use criteria and reflects the increasing effort of the international Scientific Societies to create and review in a critical way the management of diagnostic tests used by clinicians.The aim of this Italian consensus document is to address the use of multimodality imaging in the diagnosis and management of the major cardiovascular clinical scenarios, taking into consideration not only the international guidelines and scientific documents already published, but also the reality of Italian laws as well as the various professional profiles involved in patient management and availability of technological diagnostic instruments.

RESUMO

Echocardiographic quantification is crucial for the diagnosis and management of patients with acquired and congenital heart disease (CHD). In neonatal and pediatric age, the echocardiogram begins with subxiphoid, or subcostal, imaging instead of left parasternal views. This allows for the determination of visceral situs (site or location) at the beginning of an examination. Regardless of where the examination starts, the segmental approach is used to describe all of the major cardiovascular structures in sequence. Patent foramen ovale is a normal interatrial communication during fetal life. Complete anatomic closure of the foramen ovale occurs in 70-75% of adults, which means that almost 25% of the population has a patent foramen ovale. Atrial septal defects are a common congenital disorder with a prevalence of approximately 2 per 1000 live births. The reported rate of spontaneous atrial septal defect closure in the first year of life ranges from 4% to 96%. The most important predictor for spontaneous closure is the size of the defect, with smaller defects more likely to close. Systemic-to-pulmonary collateral arteries can occur in premature infants without chronic lung disease and may represent a transient phenomenon. They may be present normally after birth and then gradually disappear. Physiological valvular regurgitation is most commonly observed in the tricuspid valve among children (32.8%), followed by pulmonary regurgitation (17.2%). The ductus arteriosus usually is functionally closed within 48 h of birth, although some authors consider the patent ductus to be abnormal only after 3 months of age. Prematurity clearly increases the incidence of patent ductus arteriosus.
