Adverse effects, pharmacological interactions, and cardiovascular drugs in COVID-19 treatment.

In severe coronavirus disease (COVID)-19 patients, an extraordinary systemic inflammatory response is seen. It could impact in multiple organ disorders, specially a severe myocardial injury, an acute myocarditis results in focal or global myocardial inflammation and necrosis. Those events can be present in healthy subjects or cardiovascular (CV) patients. It is clinically associated with ventricular dysfunction exacerbation or worsening and tachyarrhythmias. It is also related to a poor outcome for CV patients with ischemic heart disease, hypertensión, and heart failure. COVID-19 patients require multiple and complex treatment that alleviates symptoms, the vast variety of agents interacts with diseases and CV drugs. Our purpose is to correlate in guidance synopsis: Adverse effects, pharmacological interactions, and CV drugs in COVID-19 treatment.

En pacientes con COVID-19 grave se ha observado una extraordinaria respuesta inflamatoria sistémica. Este impacto se traduce en múltiples trastornos de órganos, especialmente cardíacos, por lesión miocárdica grave, miocarditis aguda que resulta en inflamación focal o miocárdica global, necrosis cardiaca. Estos tremendos eventos son observados en sujetos sanos como pacientes cardiovasculares. Clínicamente asociados con nueva presentación o empeoramiento de la disfunción ventricular y taquiarritmias. Relacionado a un predictor principal de malos resultado en pacientes cardiovasculares (CV), especialmente en aquellos con cardiopatía isquémica, hipertensión e insuficiencia cardíaca. Los enfermos con COVID-19 requieren múltiples y complejos tratamientos que alivien los síntomas, esta gran variedad de agentes interactúa con enfermedades y medicamentos CV. Nuestro propósito es correlacionar, en una guía sinóptica: efectos adversos, interacciones farmacológicas y fármacos cardiovasculares en el tratamiento del COVID-19.

Endothelial cells and SARS-CoV-2: An intimate relationship.

Angiotensin-converting enzyme 2 (ACE2) is an important player of the renin-angiotensin-aldosterone system (RAAS) in regulating the conversion of angiotensin II into angiotensin (1-7). While expressed on the surface of human cells, such as lung, heart, kidney, neurons, and endothelial cells (EC), ACE2 is the entry receptor for SARS-CoV-2. Here, we would like to highlight that ACE2 is predominant on the EC membrane. Many of coronavirus disease 2019 (COVID-19) symptoms have been associated with the large recruitment of immune cells, directly affecting EC. Additionally, cytokines, hypoxia, and complement activation can trigger the activation of EC leading to the coagulation cascade. The EC dysfunction plus the inflammation due to SARS-CoV-2 infection may lead to abnormal coagulation, actively participating in thrombo-inflammatory processes resulting in vasculopathy and indicating poor prognosis in patients with COVID-19. Considering the intrinsic relationship between EC and the pathophysiology of SARS-CoV-2, EC-associated therapies such as anticoagulants, fibrinolytic drugs, immunomodulators, and molecular therapies have been proposed. In this review, we will discuss the role of EC in the lung inflammation and edema, in the disseminate coagulation process, ACE2 positive cancer patients, and current and future EC-associated therapies to treat COVID-19.

Covid-19 and surfing: problems, strategies and solutions for surfers / Covid-19 no surfe: problemas, estratégias e soluções para os atletas do surfe / Covid-19 en el surf: problemas, estrategias y soluciones para los atletas del surf

ABSTRACT The pandemic caused by coronavirus disease (COVID-19) has changed the routine of surfers, professionals and all those involved in surfing. This unusual global crisis has caused major organizational, financial and social disruption for surfers, coaches, federations and fans. The world of sports, including surfing, entered extreme and uncharted territory, in which all competitions were postponed and many beaches were closed, preventing any kind of surfing activity. The primary objective of this article is to identify potential harmful effects caused by the COVID-19 pandemic on the health of surfers, while the secondary objective is to provide practical recommendations for coaches, professional and amateur surfers to reduce the undesirable consequences of forced quarantine and direct the resumption of surfing activities while protecting the health of those involved. The main problems indicated were: the effects on body composition due to calorie imbalance, possible cardiac and pulmonary alterations caused by COVID-19, musculoskeletal symptoms and the consequences of detraining. The article also suggests recommendations for new attitudes towards surfing. Surfing is a growing sport that has been included in the upcoming Olympic Games in Tokyo. As the sport grows and becomes more professional, measures to protect the health of surfers need to be put in place. The current pandemic situation is extremely delicate and the measures proposed in this study are intended to serve as a guide for surfers and professionals in order to minimize the harmful effects of this situation. Level of Evidence IV; Type of Study: Literature review.

Cardiovascular vulnerability in COVID-19 elderly patients: getting into the biological mechanisms / Vulnerabilidad cardiovascular en adultos mayores con COVID-19: conociendo los mecanismos biológicos

The COVID-19 pandemic has had an important impact on older adults, conferring a worse prognosis. Older adults may have atypical presentations, which can delay the diagnosis of the disease, making its evolution more unfavorable. In addition to the cardiovascular damage mechanisms conferred by SARS-CoV-2 infection, the changes inherent in the aging cardiovascular and immune system favor the appearance of cardiovascular complications in a more relevant way in this population. The objective of this article will be to summarize the knowledge about cardiovascular involvement in older adults and explain its pathophysiological mechanisms, to alert about the early recognition and timely treatment of these complications.

La pandemia por COVID-19 ha impactado de forma importante en los adultos mayores, confiriéndoles un peor pronóstico. Los adultos mayores pueden tener presentaciones atípicas, las cuales pueden retrasar el diagnóstico de la enfermedad, haciendo su evolución más desfavorable. Además de los mecanismos de daño cardiovascular conferidos por la infección por SARS-CoV-2, los cambios inherentes al sistema cardiovascular e inmune ya envejecido, favorecen la aparición de complicaciones cardiovasculares de forma más relevante en esta población. El objetivo de este artículo será resumir los conocimientos sobre el involucro cardiovascular en adultos mayores y explicar los mecanismos fisiopatológicos de este, para alertar sobre el reconocimiento temprano y tratamiento oportuno de estas complicaciones.

Covid-19 and the cardiovascular system: a comprehensive review.

Cardiac injury in patients infected with the novel Coronavirus (COVID-19) seems to be associated with higher morbimortality. We provide a broad review of the clinical evolution of COVID-19, emphasizing its impact and implications on the cardiovascular system. The pathophysiology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is characterized by overproduction of inflammatory cytokines (IL-6 and TNF-α) leading to systemic inflammation and multiple organ dysfunction syndrome, acutely affecting the cardiovascular system. Hypertension (56.6%) and diabetes (33.8%) are the most prevalent comorbidities among individuals with COVID-19, who require hospitalization. Furthermore, cardiac injury, defined as elevated us-troponin I, significantly relates to inflammation biomarkers (IL-6 and C-reactive protein (CRP), hyperferritinemia, and leukocytosis), portraying an important correlation between myocardial injury and inflammatory hyperactivity triggered by viral infection. Increased risk for myocardial infarction, fulminant myocarditis rapidly evolving with depressed systolic left ventricle function, arrhythmias, venous thromboembolism, and cardiomyopathies mimicking STEMI presentations are the most prevalent cardiovascular complications described in patients with COVID-19. Moreover, SARS-CoV-2 tropism and interaction with the RAAS system, through ACE2 receptor, possibly enhances inflammation response and cardiac aggression, leading to imperative concerns about the use of ACEi and ARBs in infected patients. Cardiovascular implications result in a worse prognosis in patients with COVID-19, emphasizing the importance of precocious detection and implementation of optimal therapeutic strategies.

Potential Therapeutic Role of Purinergic Receptors in Cardiovascular Disease Mediated by SARS-CoV-2.

Novel coronavirus disease 2019 (COVID-19) causes pulmonary and cardiovascular disorders and has become a worldwide emergency. Myocardial injury can be caused by direct or indirect damage, particularly mediated by a cytokine storm, a disordered immune response that can cause myocarditis, abnormal coagulation, arrhythmia, acute coronary syndrome, and myocardial infarction. The present review focuses on the mechanisms of this viral infection, cardiac biomarkers, consequences, and the possible therapeutic role of purinergic and adenosinergic signalling systems. In particular, we focus on the interaction of the extracellular nucleotide adenosine triphosphate (ATP) with its receptors P2X1, P2X4, P2X7, P2Y1, and P2Y2 and of adenosine (Ado) with A2A and A3 receptors, as well as their roles in host immune responses. We suggest that receptors of purinergic signalling could be ideal candidates for pharmacological targeting to protect against myocardial injury caused by a cytokine storm in COVID-19, in order to reduce systemic inflammatory damage to cells and tissues, preventing the progression of the disease by modulating the immune response and improving patient quality of life.

Recomendación para la sospecha, manejo y seguimiento del compromiso cardiovascular en pacientes con Síndrome Inflamatorio Multisistémico en Pediatría asociado a COVID-19 (PIMS-TC). Declaración de Posición de la Sociedad Chilena de Pediatría (SOCHIPE) y Sociedad Chilena de Cardiología y Cirugía Cardiovascular (SOCHICAR) / Recommendation for the recognition, management and follow up of cardiovascular compromise in patients with Pediatric Multisystemic Inflammatory Syndrome associated with COVID-19 (PIMS-CT). Position statement of Chilean Scientific Societies

Desde la aparición de la pandemia por SARS-CoV-2, la población pediátrica ha sido menos afectada por la enfermedad tanto en frecuencia como en severidad. Sin embargo, desde abril de este año se han reportado casos de presentación y gravedad variables, caracterizados por fenómenos inflamato rios que afectan múltiples órganos, condición denominada Síndrome Inflamatorio Multisistémico Pediátrico (PIMS). La literatura describe frecuente compromiso cardíaco, hasta en un 80%. Este se caracteriza por injuria miocárdica con significativa elevación de biomarcadores: Troponinas séricas I/T, BNP o NT-ProBNP, unido a diversos grados de disfunción ventricular, pericarditis, valvulitis y arritmias. Además, se ha evidenciado la presencia de compromiso coronario el cual puede ocurrir hasta en un 23% de los casos, en un rango que va desde dilataciones hasta aneurismas. El seguimien to cardiológico hospitalizado y ambulatorio se ha sistematizado en base a los fenotipos clínicos de presentación: injuria miocárdica (miocarditis, valvulitis, pericarditis), shock (habitualmente de tipo "vasopléjico"), manifestaciones tipo Enfermedad de Kawasaki y aquellos casos PIMS que no cumplen con la clínica de los tres precedentes. Este último grupo es el que representa el mayor desafío en el cor to, mediano y seguimiento a largo plazo. Por esta razón se requiere un equipo multidisciplinario para su manejo. Considerando la alta frecuencia del compromiso cardíaco en el PIMS y la importancia de lograr un consenso en su manejo y seguimiento, se presentan estas recomendaciones según el estado actual del conocimiento de esta patología recientemente descrita.

Since the onset of the SARS-CoV-2 pandemic, the pediatric population has been less affected by the disease both in frequency and severity. However, since April cases of variable presentation and severity characterized by inflammatory phenomena that affect multiple organs have been reported, a condition called Multisystem Inflammatory Syndrome in Children (MIS-C). The literature has reported frequent cardiac involvement, up to 80%. This is characterized by myocardial injury with a significant increase of biomarkers such as serum troponins I and T, BNP, or NT-ProBNP coupled with varying degrees of ventricular dysfunction, pericarditis, valvulitis, and arrhythmias. Coronary compromise has also been described, which can occur in up to 23% of cases, and ranges from dila tations to aneurysms. Inpatient and outpatient cardiology follow-up has been systematized based on the clinical phenotypes such as myocardial injury (myocarditis, valvulitis, pericarditis), shock (usua lly vasoplegic), Kawasaki disease-type manifestations, and those MIS-C that do not comply with the clinic of the previous three. This last group represents the main challenge in the short-, medium- and long-term follow-up, therefore, it is necessary a multidisciplinary team for managing these patients. Considering the high frequency of cardiac compromise in MIS-C, and the importance of reaching a consensus regarding its management and follow-up, we present these recommendations according to the current state of knowledge regarding this recently described pathology.

COVID-19 and the Heart.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which causes coronavirus disease 2019 (COVID-19) has resulted in a global health crisis. Prior to the arrival of this viral pandemic, the world was already plagued with a significant burden of cardiovascular disease. With the introduction of the novel virus, the world now faces a double jeapordy. Early reports have suggested an increased risk of death in individuals with underlying cardio-metabolic disorders. The exact effects of COVID-19 on the cardiovascular system are not well determined, however lessons from prior viral epidemics suggest that such infections can trigger acute coronary syndromes, arrhythmias and heart failure via direct and indirect mechanisms. In this article, we aimed to discuss the effects and potential underlying mechanisms of COVID -19 as well as potential implications of treatments targeted against this virus on the cardiovascular system.

El síndrome respiratorio agudo severo coronavirus 2 (SARS-CoV-2) que causa la enfermedad por coronavirus (COVID-19) ha provocado una crisis en la salud global. Antes de la llegada de esta pandemia, se tenia una carga importante de enfermedad cardiovascular a nivel mundial. Con la introducción del nuevo virus, el mundo ahora se enfrenta a un doble peligro. Los primeros informes han sugerido un mayor riesgo de muerte en personas con trastornos cardio-metabólicos de base. Los efectos causados por el COVID-19, en el sistema cardiovascular aun no están bien determinados, sin embargo, el conocimiento sobre otras epidemias virales previamente ocurridas en el mundo, sugieren que estas infecciones pueden desencadenar síndromes coronarios agudos, arritmias e insuficiencia cardíaca a través de mecanismos directos e indirectos. En este artículo, nuestro objetivo fue analizar los efectos y los posibles mecanismos subyacentes de COVID -19, así como las posibles implicaciones de los tratamientos dirigidos contra este virus en el sistema cardiovascular.

Myocardial Injury Biomarkers and Cardiac Complications Associated with Mortality in Patients with COVID-19. / Biomarcadores de Lesão Miocárdica e Complicações Cardíacas Associadas à Mortalidade em Pacientes com COVID-19.

BACKGROUND: SARS-CoV-2 is an emerging RNA virus associated with a severe acute respiratory disease known as COVID-19. Although COVID-19 is predominantly a pulmonary disease, some patients have severe cardiovascular damage. We performed a quantitative evidence synthesis of clinical data, myocardial injury biomarkers, and cardiac complications associated with in-hospital death in patients with COVID-19. METHODS: We searched the databases PubMed, Embase, and Google Scholar to identify studies comparing clinical data, myocardial injury biomarkers, and cardiac complications between non-survivors and survivors of COVID-19. Effect sizes were reported as mean difference or standardized mean difference for continuous variables and risk ratio for dichotomous variables with 95% confidence intervals. A random effects model was used to pool the results. RESULTS: Six retrospective studies reporting data from 1,141 patients (832 survivors and 309 non-survivors) were included. We found that underlying cardiovascular conditions; elevation of high-sensitivity cardiac troponin I, N-terminal pro-B-type natriuretic peptide, and creatine kinase-MB; and cardiac complications were associated with increased risk of death for patients with SARS-CoV-2 infection. CONCLUSIONS: The confirmation that underlying cardiovascular conditions, elevation of myocardial injury biomarkers during COVID-19 infection, and acute cardiovascular decompensation are predictors for mortality in SARS-CoV-2 infection must encourage new research to clarify potential mechanisms and test appropriate treatments.

FUNDAMENTO: O SARS-CoV-2 é um vírus de RNA emergente associado à doença respiratória aguda grave conhecida como COVID-19. Embora a COVID-19 seja predominantemente uma doença pulmonar, alguns pacientes apresentam graves danos cardiovasculares. Realizamos uma síntese de evidências quantitativas de dados clínicos, biomarcadores de lesão miocárdica e complicações cardíacas associadas ao óbito hospitalar em pacientes com COVID-19. MÉTODOS: Buscamos nas bases de dados PubMed, Embase e Google Scholar para identificar estudos que comparassem dados clínicos, biomarcadores de lesão miocárdica e complicações cardíacas entre pacientes sobreviventes e não sobreviventes da COVID-19. Os tamanhos dos efeitos foram apresentados como diferença média ou diferença média padronizada para variáveis contínuas e razão de risco para variáveis dicotômicas, com intervalos de confiança de 95%. Foi utilizado um modelo de efeitos aleatórios para agrupar os resultados. RESULTADOS: Foram incluídos seis estudos retrospectivos que relataram dados de 1.141 pacientes (832 sobreviventes e 309 não sobreviventes). Verificamos que condições cardiovasculares subjacentes; elevação de troponina cardíaca I de alta sensibilidade; N-terminal do pró-hormônio do peptídeo natriurético do tipo B e creatina quinase-MB; e complicações cardíacas foram associadas ao aumento do risco de óbito em pacientes com infecção por SARS-CoV-2. CONCLUSÕES: A confirmação de que condições cardiovasculares subjacentes, elevação de biomarcadores de lesão miocárdica durante a infecção por COVID-19 e descompensação cardiovascular aguda são preditores de mortalidade na infecção por SARS-CoV-2 deve incentivar novas pesquisas para esclarecer possíveis mecanismos e testar tratamentos adequados.

Cardiovascular Implications in Patients Infected with Covid-19 and the Importance of Social Isolation to Reduce Dissemination of the Disease. / Implicações Cardiovasculares em Pacientes Infectados com Covid-19 e a Importância do Isolamento Social para Reduzir a Disseminação da Doença.

Respiratory symptoms, especially the development of severe acute respiratory distress syndrome, dominate the discussion and initial concerns of the population and health professionals. However, the cardiovascular system is greatly affected by these conditions and is often responsible for complications and mortality of these patients. In order to show the cardiovascular implications in patients infected with COVID-19 and the importance of social isolation as an alternative to curb the spread of the disease, a literature review was carried out based on 37 articles, in English, Portuguese and Spanish, available on Scielo and PubMed. The findings showed that cardiac complications associated with COVID-19 infection are similar to those produced by: severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS) and influenza. However, COVID-19 has a much greater and faster contamination and, unlike influenza, there is no vaccine or treatment available yet. In view of this, social isolation becomes a tool that can reduce and flatten the curve of cases and thus protect the people at higher risk, decreasing the chances of serious conditions related to the disease, potential deaths and the collapse of the country's health system.

Os sintomas respiratórios, principalmente o desenvolvimento de quadros de síndrome do desconforto respiratório agudo grave, dominam a discussão e as preocupações iniciais da população e dos profissionais de saúde. Entretanto, o sistema cardiovascular é bastante afetado por essas condições e, muitas vezes, é o responsável por complicações e mortalidade desses pacientes. Com o objetivo de mostrar as implicações cardiovasculares em pacientes infectados pela COVID-19 e a importância do isolamento social como alternativa de frear a disseminação da doença, foi realizada uma revisão da literatura com base em 37 artigos, nos idiomas inglês, português e espanhol, disponíveis na plataforma Scielo e PubMed. Os resultados mostraram que complicações cardíacas associadas à infecção pela COVID-19 são semelhantes às produzidas por: síndrome respiratória aguda grave (SARS), síndrome respiratória do Médio Oriente (MERS) e influenza. Contudo, a COVID-19 apresenta uma contaminação muito maior e mais rápida e, ao contrário da gripe por influenza, ainda não existe vacina disponível ou tratamento. Diante disso, o isolamento social passa a ser uma ferramenta que pode reduzir e achatar a curva de casos incidentes e assim preservar as pessoas que se enquadrem no grupo de risco, diminuindo as chances de quadros graves da doença, possíveis óbitos e o colapso no sistema de saúde do país.

Excerpts from the documents of Mexican positions and recommendations in cardiovascular diseases and COVID-19.

The recommendations in which the Mexican Society of Cardiology (SMC) in conjunction with the National Association of Cardiologists of Mexico (ANCAM) as well as different Mexican medical associations linked to cardiology are presented, after a comprehensive and consensual review and analysis of the topics related to cardiovascular diseases in the COVID-19 pandemic. Scientific positions are analyzed and responsible recommendations on general measures are given to patients, with personal care, healthy eating, regular physical activity, actions in case of cardio-respiratory arrest, protection of the patient and health personnel as well as precise indications in the use of non-invasive cardiovascular imaging, prescription of medications, care in specific topics such as systemic arterial hypertension, heart failure, arrhythmias and acute coronary syndromes, in addition to emphasizing electrophysiology, interventionism, cardiac surgery and in cardiac rehabilitation. The main interest is to provide the medical community with a general orientation on what to do in daily practice and patients with cardiovascular diseases in the setting of this unprecedented epidemiological crisis of COVID-19.

Se presentan las recomendaciones en las cuales la Sociedad Mexicana de Cardiología (SMC) en conjunto con la Asociación Nacional de Cardiólogos de México (ANCAM), así como diferentes asociaciones médicas mexicanas vinculadas con la cardiología, después de una revisión y análisis exhaustivo y consensuado sobre los tópicos relacionados con las enfermedades cardiovasculares en la pandemia de COVID-19, se analizan posturas científicas y se dan recomendaciones responsables sobre medidas generales a los pacientes, con cuidados personales, alimentación saludable, actividad física regular, acciones en caso de paro cardiorrespiratorio, la protección del paciente y del personal de salud así como las indicaciones precisas en el uso de la imagen cardiovascular no invasiva, la prescripción de medicamentos, cuidados en tópicos específicos como en la hipertensión arterial sistémica, insuficiencia cardiaca, arritmias y síndromes coronarios agudos, además de hacer énfasis en los procedimientos de electrofisiología, intervencionismo, cirugía cardiaca y en la rehabilitación cardiaca. El interés principal es brindar a la comunidad médica una orientación general sobre el quehacer en la práctica cotidiana y pacientes con enfermedades cardiovasculares en el escenario esta crisis epidemiológica sin precedentes de COVID-19.

Recommendations for the care of patients with heart failure and COVID-19.

The COVID-19 pandemic decreed by the World Health Organization (WHO) since March 12, 2020 is wreaking havoc globally and it is a true economic, social and health challenge. Although the clinical manifestations of COVID-19 are respiratory symptoms, some patients also have cardiological symptoms. Among patients with cardiological conditions2 they represent a group of higher risk and, in fact, they are a particularly vulnerable group, due to their higher risk of contagion and greater severity in case of acquiring the disease1 those with heart failure (HF), including heart transplant (CT) and ventricular assists, as well as patients with pulmonary arterial hypertension (PAH). HF is the main chronic cardiovascular disease and patients in this group are the most vulnerable for the development of more serious clinical symptoms after suffering the infection, and to a greater extent cases with advanced HF3. In fact, HF is one of the most frequent complications in patients with COVID-194. Likewise, transplant patients who require immunosuppressants to avoid graft rejection, constitute a population especially susceptible to infection and to develop more serious processes. This situation has made the National Association of Cardiologists of Mexico (ANCAM) and the Mexican Society of Cardiology (SMC) together with their respective chapters, have prepared the following recommendations for medical personnel, who participate in the care of this special group of patients in the different clinical settings, who suffer or not, of COVID-19.

La pandemia por COVID-19 decretada por la Organización Mundial de la Salud (OMS) desde el 12 de marzo de 2020 está produciendo estragos a nivel mundial y es un verdadero reto económico, social y sanitario. Aunque las manifestaciones clínicas del COVID-19 son síntomas respiratorios, algunos pacientes también tienen síntomas cardiológicos. Dentro de los pacientes con afecciones cardiológicas2 suponen un grupo de mayor riesgo y que de hecho son un grupo especialmente vulnerable, por su mayor riesgo de contagio y mayor gravedad en caso de adquirir la enfermedad1 aquellos con insuficiencia cardiaca (IC), incluyendo al trasplante cardiaco (TC) y las asistencias ventriculares, así como los pacientes con hipertensión arterial pulmonar (HAP). La IC es la principal patología cardiovascular crónica y los pacientes en este grupo son los más vulnerables para el desarrollo de cuadros clínicos más graves tras sufrir la infección, y en mayor medida los casos con IC avanzada3. De hecho, la IC es unas de las complicaciones más frecuentes en los pacientes con COVID-194. De igual forma, los pacientes trasplantados que requieren de los inmunosupresores para evitar el rechazo del injerto, constituyen una población especialmente susceptible a la infección y a desarrollar procesos más graves. Esta situación ha hecho que la Asociación Nacional de Cardiólogos de México (ANCAM) y la Sociedad Mexicana de Cardiología (SMC) junto con sus respectivos capítulos, hayan elaborado las siguientes recomendaciones para el personal médico, que participa en la atención de este grupo especial de pacientes en los diferentes escenarios clínicos, que padezcan o no, COVID-19.

Recommendations for the care of patients with diabetes mellitus with risk factors or established cardiovascular disease and SARS-CoV-2mellitus con factores de riesgo o enfermedad cardiovascular establecida y SARS-CoV-2.

A review is carried out to examine the risk of patients suffering from diabetes mellitus in the context of general morbidity and mortality and related to infection by SARS-CoV-2. Likewise, the general recommendations for food and the prevention of comorbidities that most these patients suffer most frequently are also studied. Finally, a review of the pharmacological recommendations on both oral and parenteral treatment in the outpatient, in hospitalization and in critical states infected with SARS-CoV-2 is made.

Se realiza una revisión sobre el riesgo de los pacientes que padecen diabetes mellitus en el contexto de morbimortalidad general y relacionada a infección por el coronavirus 2 del síndrome respiratorio agudo grave (SARS-CoV-2). Así mismo se repasan las recomendaciones generales, de alimentación y de la prevención de las comorbilidades que más frecuentemente padecen dichos enfermos. Finalmente se hace una revisión de las recomendaciones farmacológicas sobre el tratamiento tanto oral como parenteral en el paciente ambulatorio, en la hospitalización y en estados críticos infectados por el SARS-CoV-2.

COVID-19: Updated Data and its Relation to the Cardiovascular System. / COVID-19: Dados Atualizados e sua Relação Com o Sistema Cardiovascular.

In December 2019, a new human coronavirus, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or coronavirus disease 2019 (COVID-19) by the World Health Organization, emerged in the city of Wuhan, China. Spreading globally, it is now considered pandemic, with approximately 3 million cases worldwide at the end of April. Its symptoms include fever, cough, and headache, but the main one is shortness of breath. In turn, it is believed that there is a relationship between COVID-19 and damage to the heart muscle, and hypertensive and diabetic patients, for example, seem to have worse prognosis. Therefore, COVID-19 may worsen in individuals with underlying adverse conditions, and a not negligible number of patients hospitalized with this virus had cardiovascular or cerebrovascular diseases. Systemic inflammatory response and immune system disorders during disease progression may be behind this association. In addition, the virus uses angiotensin-converting enzyme (ACE) receptors, more precisely ACE2, to penetrate the cell; therefore, the use of ACE inhibitor drugs and angiotensin receptor blockers could cause an increase in these receptors, thus facilitating the entry of the virus into the cell. There is, however, no scientific evidence to support the interruption of these drugs. Since they are fundamental for certain chronic diseases, the risk and benefit of their withdrawal in this scenario should be carefully weighed. Finally, cardiologists and health professionals should be aware of the risks of infection and protect themselves as much as possible, sleeping properly and avoiding long working hours.

Em dezembro de 2019, um novo coronavírus humano, chamado síndrome respiratória aguda grave do coronavírus 2 (SARS-CoV-2) ou nomeado doença de coronavírus (COVID-19) pela Organização Mundial da Saúde, surgiu na cidade de Wuhan, China. Difundido globalmente, é atualmente considerado pandêmico, com aproximadamente 3 milhões de casos no mundo no final de abril. Seus sintomas incluem febre, tosse, dor de cabeça e falta de ar, esse último considerado o sintoma principal. Por sua vez, acredita-se que haja uma relação entre o COVID-19 e danos ao músculo cardíaco, e pacientes com hipertensão e diabetes, por exemplo, parecem apresentar prognóstico pior. Portanto, o COVID-19 pode piorar em indivíduos com condições adversas subjacentes. Um número não negligenciável de pacientes internados com este vírus tinham doenças cardiovasculares ou cerebrovasculares. A resposta inflamatória sistêmica e distúrbios do sistema imunológico durante a progressão da doença podem estar por trás dessa associação. Além disso, o vírus usa os receptores da enzima conversora da angiotensina (ECA), mais especificamente da ECA2, para penetrar nas células; portanto, o uso de fármacos inibidores de ECA e bloqueadores de receptores de angiotensina pode causar um aumento nestes receptores, assim facilitando a entrada do vírus na célula. No entanto, não há evidências científicas que apóiem a interrupção desses medicamentos. Considerando que são fundamentais para o manejo de certas doenças crônicas, os riscos e benefícios da sua retirada devem ser cuidadosamente ponderados neste cenário. Finalmente, cardiologistas e profissionais de saúde devem estar cientes dos riscos de infecção e se proteger o máximo possível, dormindo adequadamente e evitando longos turnos de trabalho.

In face of the pandemic of the novel coronavirus disease 2019 (COVID-19), the management of patients with cardiovascular risk factors and/or disease is challenging. The cardiovascular complications evidenced in patients with COVID-19 derive from several mechanisms, ranging from direct viral injury to complications secondary to the inflammatory and thrombotic responses to the infection. The proper care of patients with COVID-19 requires special attention to the cardiovascular system aimed at better outcomes.

Frente à pandemia da doença causada pelo novo coronavírus (COVID-19), o manejo do paciente com fator de risco e/ou doença cardiovascular é desafiador nos dias de hoje. As complicações cardiovasculares evidenciadas nos pacientes com COVID-19 resultam de vários mecanismos, que vão desde lesão direta pelo vírus até complicações secundárias à resposta inflamatória e trombótica desencadeada pela infecção. O cuidado adequado do paciente com COVID-19 exige atenção ao sistema cardiovascular em busca de melhores desfechos.

Abstract In December 2019, a new human coronavirus, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or coronavirus disease 2019 (COVID-19) by the World Health Organization, emerged in the city of Wuhan, China. Spreading globally, it is now considered pandemic, with approximately 3 million cases worldwide at the end of April. Its symptoms include fever, cough, and headache, but the main one is shortness of breath. In turn, it is believed that there is a relationship between COVID-19 and damage to the heart muscle, and hypertensive and diabetic patients, for example, seem to have worse prognosis. Therefore, COVID-19 may worsen in individuals with underlying adverse conditions, and a not negligible number of patients hospitalized with this virus had cardiovascular or cerebrovascular diseases. Systemic inflammatory response and immune system disorders during disease progression may be behind this association. In addition, the virus uses angiotensin-converting enzyme (ACE) receptors, more precisely ACE2, to penetrate the cell; therefore, the use of ACE inhibitor drugs and angiotensin receptor blockers could cause an increase in these receptors, thus facilitating the entry of the virus into the cell. There is, however, no scientific evidence to support the interruption of these drugs. Since they are fundamental for certain chronic diseases, the risk and benefit of their withdrawal in this scenario should be carefully weighed. Finally, cardiologists and health professionals should be aware of the risks of infection and protect themselves as much as possible, sleeping properly and avoiding long working hours.
