Abstract Background Pharmacoinvasive strategy is an alternative when primary percutaneous coronary intervention (PCI) is not feasible. Objectives This study aimed to evaluate the effects of early pharmacoinvasive strategy on the infarct size and left ventricular ejection fraction in elderly and non-elderly patients. The role of inflammatory markers was also examined. Methods Patients (n=223) with ST segment elevation myocardial infarction (STEMI) were prospectively included and submitted to pharmacological thrombolysis in the first six hours, and underwent coronary angiogram and PCI when necessary, in the first 24 hours. Blood samples were collected in the first day (D1) and after 30 days (D30). Cardiac magnetic resonance imaging (cMRI) was performed at D30. Significance was set at p<0.05. Results Elderly and non-elderly patients showed similar percentage of infarcted mass (13.7 [6.9-17.0] vs. 14.0 [7.3-26.0], respectively, p=0.13) (median [interquartile range]). However, elderly patients had better left ventricular ejection fraction (53 [45-62] vs. 49 [39-58], p=0.025). Titers of interleukin (IL)1beta, IL-4, IL-6, and IL-10 did not differ between D1 and D30, but elderly patients had higher titers for IL-18 at D1 and D30. Absolute numbers of B and T lymphocytes were similar in both groups at D1 and D30, but elderly patients had higher neutrophil/lymphocyte ratio at D30. Multivariate linear regression analysis of cMRI outcomes in the whole population showed that the independent predictors were not different between elderly and non-elderly patients. Conclusion Pharmacoinvasive strategy in elderly patients was associated with small differences in inflammatory parameters, similar infarct size and better left ventricular function than non-elderly patients.

Resumo Fundamento A estratégia farmacoinvasiva é uma alternativa na inviabilidade da intervenção coronária percutânea primária (ICP). Objetivos Este estudo teve como objetivo avaliar os efeitos da estratégia farmacoinvasiva precoce sobre o tamanho da área infartada e a fração de ejeção ventricular esquerda em pacientes idosos e não idosos. O papel dos marcadores inflamatórios também foi avaliado. Métodos Pacientes (n=223) com infarto do miocárdio com elevação do segmento ST (IAMCSST) foram prospectivamente incluídos e submetidos à trombólise medicamentosa nas primeiras seis horas, e à angiografia coronariana e à ICP, quando necessária, nas primeiras 24 horas. As amostras de sangue foram coletadas no primeiro dia (D1) e 30 dias após (D30). A ressonância magnética cardíaca foi realizada no D30. O nível de significância estatística foi estabelecido em p<0,05. Resultados Pacientes idosos e não idosos apresentaram porcentagem similares de massa infartada [13,7 (6,9-17,0) vs. 14,0 (7,3-26,0), respectivamente p=0,13)] [mediana (intervalo interquartil)]. No entanto, os pacientes idosos apresentaram maior fração de ejeção ventricular esquerda [53 (45-62) vs. 49 (39-58), p=0,025)]. As concentrações de interleucina (IL)1beta, IL-4, IL-6, e IL-10 não foram diferentes entre D1 e D30, mas pacientes idosos apresentaram níveis mais elevados de IL-18 em D1 e D30. O número absoluto de linfócitos B e T foram similares em ambos os grupos em D1 e D30, porém, pacientes idosos apresentaram uma razão neutrófilo-linfócito mais alta em D30. A análise de regressão linear multivariada dos desfechos de RMC de toda a população do estudo mostrou que os preditores independentes não foram diferentes entre pacientes idosos e não idosos. Conclusão A estratégia farmacoinvasiva em pacientes idosos foi associada a pequenas diferenças nos parâmetros inflamatórios, tamanho do infarto similar, e melhor função ventricular esquerda em comparação a pacientes não idosos

ABSTRACT Objective The radiological and functional lung sequelae in COVID-19 survivors remain unclear. We compared the chest computed tomography findings of COVID-19 patients with normal and abnormal pulmonary function test results in the post-recovery phase. Methods The data of consecutive patients who underwent pulmonary function tests and chest computed tomography within 14 days after recovery from COVID-19 at two medical centers between May and October 2020 were collected retrospectively. Two thoracic radiologists who were blinded to the clinical information and pulmonary function test results classified the patients according to the computed tomography features, evidence of fibrotic-like changes, and semi-quantitative quantification of the extent of pulmonary abnormalities. The clinical characteristics and computed tomography findings of patients with normal pulmonary function test results were compared with those of patients with abnormal results. Results A total of 101 COVID-19 survivors, comprising 48 ambulatory and 53 hospitalized patients, were included at a median of 95 days from initial symptom onset. Computed tomography revealed fibrotic-like changes in 10.9% of patients. A reduction in the diffusion capacity of carbon monoxide was the most common lung function abnormality (19.8%). Abnormal diffusion capacity of carbon monoxide was associated with the presence and extension of lung opacities on chest computed tomography scans and fibrotic pulmonary abnormalities. The sensitivity, specificity, and accuracy of reduced diffusion capacity of carbon monoxide for detecting fibrotic-like pulmonary changes on chest computed tomography scans were 72.7%, 87.8%, and 86.1%, respectively. Conclusion Our study suggests that the presence of an abnormal diffusion capacity of carbon monoxide in the post-recovery phase of COVID-19 is associated with a greater risk of long-term parenchymal lung disease, as evidenced by the presence of fibrotic-like changes on chest computed tomography scans, such as traction bronchiectasis and architectural distortion.

ABSTRACT Objective: To evaluate anthropometric and clinical data, muscle mass, subcutaneous fat, spine bone mineral density, extent of acute pulmonary disease related to COVID-19, quantification of pulmonary emphysema, coronary calcium, and hepatic steatosis using chest computed tomography of hospitalized patients with confirmed diagnosis of COVID-19 pneumonia and verify its association with disease severity. Methods: A total of 123 adults hospitalized due to COVID-19 pneumonia were enrolled in the present study, which evaluated the anthropometric, clinical and chest computed tomography data (pectoral and paravertebral muscle area and density, subcutaneous fat, thoracic vertebral bodies density, degree of pulmonary involvement by disease, coronary calcium quantification, liver attenuation measurement) and their association with poorer prognosis characterized through a combined outcome of intubation and mechanical ventilation, need of intensive care unit, and death. Results: Age (p=0.013), body mass index (p=0.009), lymphopenia (p=0.034), and degree of pulmonary involvement of COVID-19 pneumonia (p<0.001) were associated with poor prognosis. Extent of pulmonary involvement by COVID-19 pneumonia had an odds ratio of 1,329 for a poor prognosis and a cutoff value of 6.5 for increased risk, with a sensitivity of 64.9% and specificity of 67.1%. Conclusion: The present study found an association of high body mass index, older age, extent of pulmonary involvement by COVID-19, and lymphopenia with severity of COVID-19 pneumonia in hospitalized patients.

RESUMO A opacidade em vidro fosco é uma alteração muito frequente e pouco específica na tomografia computadorizada de tórax. Ela admite grande leque de diagnósticos diferenciais no contexto agudo, desde pneumonias virais, como as causadas pelo vírus influenza, pela doença do coronavírus 2019 e pelo citomegalovírus, até mesmo lesões de origem não infecciosa, como vaping , infarto pulmonar, hemorragia alveolar e edema pulmonar. Para essa diferenciação diagnóstica, deve-se correlacionar o vidro fosco com os demais achados nos exames de imagem, exames laboratoriais e quadro clínico do paciente. É de suma importância, no contexto de pandemia, recordar as demais patologias com os achados semelhantes aos da doença do coronavírus 2019 nos exames de imagem.

ABSTRACT Ground-glass opacity is a very frequent and unspecified finding in chest computed tomography. Therefore, it admits a wide range of differential diagnoses in the acute context, from viral pneumonias such as influenza virus, coronavirus disease 2019 and cytomegalovirus and even non-infectious lesions, such as vaping, pulmonary infarction, alveolar hemorrhage and pulmonary edema. For this diagnostic differentiation, ground glass must be correlated with other findings in imaging tests, with laboratory tests and with the patients’ clinical condition. In the context of a pandemic, it is extremely important to remember the other pathologies with similar findings to coronavirus disease 2019 in the imaging exams.

RESUMO Objetivo Avaliar a acurácia de uma estratégia de rastreamento de hipertensão pulmonar baseada na combinação de dados de ecocardiograma com as medidas derivadas da tomografia computadorizada (diâmetro da artéria pulmonar e razão entre diâmetro da artéria pulmonar e diâmetro da aorta ascendente) em pacientes pneumopatas crônicos encaminhados para transplante pulmonar. Métodos Estudo observacional retrospectivo realizado com pacientes com enfisema e fibrose pulmonar avaliados para transplante entre 2012 e 2016. Definiu-se hipertensão pulmonar como pressão arterial pulmonar média ≥25mmHg, ou entre 21 a 24mmHg, com resistência vascular pulmonar >3 unidades Wood no cateterismo direito. As medidas tomográficas foram realizadas por dois radiologistas independentes. Resultados Foram incluídos 13 pacientes com enfisema e 19 com fibrose pulmonar, sendo 18 com hipertensão pulmonar. Houve alta concordância entre os radiologistas em relação às medidas tomográficas (coeficientes de correlação intraclasse para diâmetro da artéria pulmonar de 0,936 e diâmetro da artéria pulmonar/diâmetro da aorta ascendente de 0,940). As áreas abaixo da curva ROC de diâmetro da artéria pulmonar, diâmetro da artéria pulmonar/diâmetro da aorta ascendente, e pressão sistólica da artéria pulmonar como preditores de hipertensão pulmonar foram 0,540, 0,629 e 0,783, respectivamente. A sensibilidade, especificidade e valor preditivo negativo da pressão de sistólica de artéria pulmonar ≥40mmHg foram 67%, 79% e 65%, respectivamente. O critério combinado de diâmetro da artéria pulmonar/diâmetro da aorta ascendente >1 e/ou pressão sistólica da artéria pulmonar ≥40mmHg mostrou sensibilidade de 72%, especificidade de 79%, e valor preditivo negativo de 69%. Conclusão Os diâmetros da artéria pulmonar e da aorta ascendente foram altamente reprodutíveis. A associação entre diâmetro da artéria pulmonar e diâmetro da aorta ascendente >1 e/ou pressão sistólica da artéria pulmonar ≥40mmHg melhorou a sensibilidade e o valor preditivo negativo para rastreamento de hipertensão pulmonar. Essa estratégia requer validação prospectiva para se avaliarem segurança e custo-efetividade.

ABSTRACT Objective To examine the accuracy of a pulmonary hypertension screening strategy based on a combination of echocardiographic data and tomographic measurements (pulmonary artery diameter and pulmonary artery diameter to ascending aorta diameter ratio) in patients with chronic lung disease referred for lung transplantation. Methods A retrospective observational study with patients with pulmonary emphysema or fibrosis referred for transplantation between 2012 and 2016. Pulmonary hypertension was defined as mean pulmonary artery pressure ≥25mmHg, or between 21 and 24mmHg, with pulmonary vascular resistance >3 Wood units on right heart catheterization. Tomographic measurements were made by two independent radiologists. Results This sample comprised 13 patients with emphysema and 19 patients with pulmonary fibrosis. Of these, 18 had pulmonary hypertension. The level of agreement in tomographic measurements made by radiologists was high (intraclass correlation coefficients 0.936 and 0.940, for pulmonary artery diameter and pulmonary artery diameter to ascending aorta diameter ratio, respectively). Areas under the ROC curves constructed for pulmonary artery diameter, pulmonary artery diameter to ascending aorta diameter ratio, and pulmonary artery systolic pressure as predictors of pulmonary hypertension were 0.540, 0.629 and 0.783, respectively. The sensitivity, specificity and negative predictive value of pulmonary artery systolic pressure ≥40mmHg were 67%, 79% and 65%, respectively. The combined criterion (pulmonary artery diameter to ascending aorta diameter ratio >1 and/or pulmonary artery systolic pressure ≥40mmHg) achieved sensitivity of 72%, specificity of 79%, and a negative predictive value of 69%. Conclusion Measurements of pulmonary artery and ascending aorta diameter were highly reproducible. The association of pulmonary artery and aortic diameter >1 and/or pulmonary artery systolic pressure ≥40mmHg improved the sensitivity and the negative predictive value for pulmonary hypertension screening. This strategy demands prospective validation to assess safety and cost-effectiveness.

RESUMO A comunicação eficiente entre a equipe médica é um fator importante no diagnóstico e tratamento precoce e adequado dos pacientes. A terminologia utilizada em relatórios de exames radiológicos aparece nesse contexto como um elo importante entre radiologistas e os demais integrantes da equipe médica. Portanto, a heterogeneidade no uso de termos em relatórios é importante mas ainda pouco discutida. Este artigo é resultado de uma extensa revisão da nomenclatura radiológica em radiologia torácica, englobando pela primeira vez termos utilizados em vários métodos (radiografia, TC e RM), desenvolvida por radiologistas brasileiros e portugueses. O objetivo desta revisão da terminologia médica foi criar uma linguagem padronizada para os profissionais médicos e as equipes multidisciplinares.

ABSTRACT Effective communication among members of medical teams is an important factor for early and appropriate diagnosis. The terminology used in radiology reports appears in this context as an important link between radiologists and other members of the medical team. Therefore, heterogeneity in the use of terms in reports is an important but little discussed issue. This article is the result of an extensive review of nomenclature in thoracic radiology, including for the first time terms used in X-rays, CT, and MRI, conducted by radiologists from Brazil and Portugal. The objective of this review of medical terminology was to create a standardized language for medical professionals and multidisciplinary teams.

Resumo Fundamento Pacientes com infarto agudo do miocárdio podem apresentar uma grande área infartada e disfunção ventricular mesmo com trombólise e revascularização precoces. Objetivo Investigar o comportamento das citocinas circulantes em pacientes com infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMCSST) e a relação delas com a função ventricular. Métodos No estudo BATTLE-AMI (Avaliação dos Linfócitos Tipos B e T no Infarto Agudo do Miocárdio), os pacientes com IAMCSST foram tratados com uma estratégia farmacoinvasiva. Os níveis de citocinas (IL-1β, IL-4, IL-6, IL-10 e IL-18) no plasma foram testados através de ensaio de imunoadsorção enzimática (ELISA) no início do estudo e após 30 dias. A massa infartada e a fração de ejeção ventricular esquerda (FEVE) foram examinadas por ressonância magnética cardíaca 3-T. Valores de p menores que 0,05 foram considerados significativos. Resultados Na comparação com o início do estudo, níveis mais baixos foram detectados para IL-1β (p = 0,028) e IL-18 (p < 0,0001) após 30 dias do IAMCSST, enquanto níveis mais altos foram observados para IL-4 (p = 0,001) e IL-10 (p < 0,0001) no mesmo momento. Em contrapartida, nenhuma mudança foi detectada nos níveis de IL-6 (p = 0,63). Os níveis da proteína C-reativa de alta sensibilidade e de IL-6 se correlacionaram no início do estudo (rho = 0,45, p < 0,0001) e 30 dias após o IAMCSST (rho = 0,29, p = 0,009). No início do estudo, a correlação entre os níveis de IL-6 e FEVE também foi observada (rho = -0,50, p = 0,004). Conclusões Durante o primeiro mês pós-infarto agudo do miocárdio, observamos uma melhora significativa no balanço das citocinas pró e anti-inflamatórias, exceto da IL-6. Esses achados sugerem risco inflamatório residual. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)

Abstract Background Patients with acute myocardial infarction may have a large infarcted area and ventricular dysfunction despite early thrombolysis and revascularization. Objective To investigate the behavior of circulating cytokines in patients with ST-segment elevation myocardial infarction (STEMI) and their relationship with ventricular function. Methods In the BATTLE-AMI (B and T Types of Lymphocytes Evaluation in Acute Myocardial Infarction) trial, patients with STEMI were treated with a pharmacoinvasive strategy. The plasma levels of cytokines (IL-1 β , IL-4, IL-6, IL-10, and IL-18) were tested using enzyme-linked immunosorbent assay (ELISA) at baseline and after 30 days. Infarcted mass and left ventricular ejection fraction (LVEF) were examined by 3-T cardiac magnetic resonance imaging. All p-values < 0.05 were considered statistically significant. Results Compared to baseline, lower levels were detected for IL-1 β (p = 0.028) and IL-18 (p < 0.0001) 30 days after STEMI, whereas higher levels were observed for IL-4 (p = 0.001) and IL-10 (p < 0.0001) at that time point. Conversely, no changes were detected for IL-6 levels (p = 0.63). The levels of high-sensitivity C-reactive protein and IL-6 correlated at baseline (rho = 0.45, p < 0.0001) and 30 days after STEMI (rho = 0.29, p = 0.009). At baseline, correlation between IL-6 levels and LVEF was also observed (rho = -0.50, p = 0.004). Conclusions During the first month post-MI, we observed a marked improvement in the balance of pro- and anti-inflammatory cytokines, except for IL-6. These findings suggest residual inflammatory risk. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)

RESUMO A COVID-19 foi declarada uma pandemia no início de 2020. Constatou-se, inicialmente, que as principais manifestações desse novo vírus ocorrem por meio de sintomas respiratórios e constitucionais. A tomografia do tórax foi eleita o exame de imagem para avaliar a extensão do comprometimento pulmonar e como um fator preditivo do prognóstico para a doença. No entanto, à medida que novos estudos são produzidos, o envolvimento gastrointestinal da COVID-19 torna-se mais evidente, com relatos de pacientes que manifestaram principalmente ou apenas sintomas gastrointestinais no decorrer da doença. Em alguns casos, a investigação inicial é realizada no pronto-socorro, com tomografia computadorizada do abdome. Relatamos uma série de casos de dez pacientes que compareceram ao serviço de emergência da instituição com uma queixa principal gastrointestinal e foram submetidos inicialmente a uma tomografia computadorizada de abdome como primeira investigação. Embora a maioria dos pacientes não tenha apresentado alterações significativas nas imagens abdominais, eles apresentaram achados pulmonares visualizados nas bases pulmonares, que depois foram caracterizadas como achados pulmonares típicos de COVID-19 nas tomografias de tórax subsequentes. Apenas um paciente apresentou achados atípicos para COVID-19 na tomografia. Todos os pacientes tiveram reação em cadeia da polimerase em tempo real positiva para o novo coronavírus. É muito importante alertar os radiologistas, principalmente os radiologistas abdominais, da possibilidade de sintomas gastrointestinais isolados no contexto da COVID-19. Além disso, deve ser um hábito para todos os radiologistas avaliar as bases pulmonares nas tomografias de abdome, local comumente afetado pela COVID-19.

ABSTRACT The COVID-19 became a pandemic in early 2020. It was found, at first, that the main manifestations of this new virus occur through respiratory and constitutional symptoms. Therefore, chest tomography was elected as the best imaging test to assess the extent of pulmonary involvement and as a good prognostic predictor for the disease. However, as new studies were produced, the gastrointestinal involvement of COVID-19 becomes more evident, with reports from patients who manifested mainly or only gastrointestinal symptoms in the course of the disease. Thus, in some cases, the initial investigation is carried out at the emergency department with an abdominal computed tomography. We report a case series of ten patients who came to the emergency department of our institution with a chief gastrointestinal complaint, and were initially submitted to an abdominal computed tomography as the first investigation. Although most of the patients did not have significant changes in the abdominal images, most reported patients had pulmonary findings visualized at the lung bases, which were later designated as typical COVID-19 pulmonary findings on chest computed tomography. Only one patient had atypical COVID-19 lung changes on chest computed tomography. All patients had a positive real-time polymerase chain reaction for COVID-19. It is imperative to alert radiologists, especially abdominal radiologists, with the possibility of COVID-19 isolated gastrointestinal symptoms. Besides, it must become a habit to radiologists to assess the pulmonary basis on abdominal scans, a site commonly affected by the new coronavirus.

RESUMO A doença causada pelo novo coronavírus (SARS-CoV-2) surgiu no final de 2019 em Wuhan, província de Hubei, na China, e apresentou um crescimento exponencial naquele país, alastrando-se posteriormente para todos os continentes, sendo agora classificada como uma pandemia. Dada a magnitude alcançada, o interesse científico pela doença também tem crescido na literatura mundial, incluindo suas manifestações nos exames de imagem, particularmente na TC. Até o presente momento, não existem séries de casos publicadas no Brasil, motivo pelo qual nosso objetivo foi descrever os achados tomográficos em uma série inicial de doze pacientes.

ABSTRACT The disease caused by the new coronavirus (SARS-CoV-2), designated COVID-19, emerged in late 2019 in China, in the city of Wuhan (Hubei province), and showed exponential growth in that country. It subsequently spread to all continents, and infection with SARS-CoV-2 is now classified as a pandemic. Given the magnitude achieved, scientific interest in COVID-19 has also grown in the international literature, including its manifestations on imaging studies, particularly on CT. To date, no case series have been published in Brazil. Therefore, our objective was to describe the CT findings in an initial series of 12 patients.
