Abstract Background Coronavirus disease 2019 (Covid-19) can lead to severe respiratory distress and acute cardiac injury, but it is unclear how often it can cause cardiac dysfunction. Objective In this systematic review, we aimed to summarize the main echocardiographic findings in patients with Covid-19. Methods We systematically searched in PUBMED, EMBASE, LILACS and Cochrane databases, in addition MedRxiv and Scielo preprints from inception to July 21st, 2021. Studies reporting echocardiographic data in patients with Covid-19 were included. Demographic characteristics, previous […]

Introduction Vaccination is one of the most important breakthroughs of modern medicine and constitute a major advance in the prevention of infectious diseases. Overall, vaccines are effective and have an excellent general safety profile. In fact, reports of severe adverse effects following vaccination are extremely rare and idiosyncratic. As the vaccine’s mechanism of action is based on the host immune response, a close relationship with autoimmunity cannot be disregarded. Cases of immunologic reactogenicity, such as Guillain-Barré syndrome and acute myocarditis […]

Dear Editor, We would like to share ideas on the publication “Prognostic Value of Troponin-T and B-Type Natriuretic Peptide in Patients Hospitalized for COVID-19 [1].” Almeida Jr. et al. reported using Memory box as a tool to support grief and concluded that “In the first 24h of admission, TnT, but not BNP, was an independent marker of mortality or need for invasive mechanical ventilation.” In COVID-19, cardiac complication is possible and is common in severe infection. Myocardial involvement is a […]

Abstract Background: The underlying mechanisms by which rheumatic heart disease (RHD) lead to severe valve dysfunction are not completely understood. Objective: The present study evaluated the histopathological changes in mitral valves (MV) seeking an association between the pattern of predominant valvular dysfunction and histopathological findings. Methods: In 40 patients who underwent MV replacement due to RHD, and in 20 controls that underwent heart transplant, histological aspects of the excised MV were analyzed. Clinical and echocardiographic data were also collected. Histological […]

Abstract Background Increased risk of new-onset diabetes with statins challenges the long-term safety of this drug class. However, few reports have analyzed this issue during acute coronary syndromes (ACS). Objective To explore the association between early initiation of statin therapy and blood glucose levels in patients admitted with ACS. Methods This was a retrospective analysis of patients hospitalized with ACS. Statin-naïve patients were included and divided according to their use or not of statins within the first 24 hours of […]

Abstract Background The incidence of myocardial injury (MI) in patients with COVID-19 in Brazil and the prognostic impact of MI have not been elucidated. Objectives To describe the incidence of MI in patients with COVID-19 in the intensive care unit (ICU) and to identify variables associated with its occurrence. The secondary objective was to assess high-sensitivity troponin I as a predictor of in-hospital mortality. Methods Retrospective, observational study conducted between March and April 2020 with cases of confirmed COVID-19 admitted […]

Introduction Acute COVID-19 cardiovascular syndrome has been the term proposed to describe changes in the cardiovascular system associated with SARS-CoV-2 infection. The most common manifestations of cardiovascular involvement are myocardial injury, myocarditis, myocardial infarction with nonobstructive coronary arteries (MINOCA), arrhythmias, Takotsubo syndrome, pericardial effusion, heart failure (HF), and thromboembolic phenomena ()., Here, we emphasize myocardial injury, myocarditis, Takotsubo syndrome and the occurrence of COVID-19 in patients with preexisting HF. […]

Introduction Sports competitions were taking place everywhere in 2019, but the novel coronavirus (SARS-CoV-2) has changed the sports scenario around the globe lately. In March 2020, the World Health Organization (WHO) declared COVID-19 (a disease caused by the SARS-CoV-2 virus) pandemic and social isolation was adopted by several governments, prohibiting sporting events. Whereas public authorities have started the process of relaxing social isolation, medical experts have been discussing the best way to evaluate athletes who had COVID-19 aiming a safe […]
