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 cardiovascular disease (CVD), and echocardiographic findings were extracted. We performed a meta-analysis of proportions to estimate the main echocardiographic findings. The level of significance was p < 0.05. RESULTS: From 11,233 studies, 38 fulfilled inclusion criteria and were included in the meta-analysis. The estimated proportions of left ventricular (LV) systolic dysfunction were 25% (95%CI: 19, 31; I293%), abnormal global longitudinal strain 34% (95% CI 23, 45; I290%), righ ventricular (RV) systolic dysfunction 17% (95%CI 13, 21; I290%), pericardial effusion 17% (95%CI: 9, 26; I297%), and pulmonary hypertension 23% (95%CI: 15, 33, I2 96%). LV systolic dysfunction was directly associated with study-specific prevalence of previous abnormal echocardiogram (p<0.001). The proportion of patients in mechanical ventilation, indicating severity of disease, did not explain the heterogeneity in the proportions of LV dysfunction (p=0.37). CONCLUSION: Among hospitalized patients with Covid-19, LV dysfunction has been reported in one quarter, with smaller proportions of right ventricular dysfunction, pericardial effusion and pulmonary hypertension. However, there was a higher proportion of LV dysfunction among studies reporting the presence of prior heart disease, which suggests that cardiac dysfunction was mostly pre-existing.
FUNDAMENTOS: A doença do coronavírus 2019 (Covid-19) pode levar à insuficiência respiratória grave e lesão cardíaca aguda, mas não está claro com que frequência ela pode causar disfunção cardíaca. OBJETIVOS: Nesta revisão sistemática, nosso objetivo foi resumir os principais achados ecocardiográficos em pacientes com Covid-19. MÉTODOS: Conduzimos uma busca sistemática nos bancos de dados PUBMED, EMBASE, LILACS e Cochrane, além de artigos não pulicados ( preprints ) no MedRxiv e Scielo desde o início até 21 de julho de 2021. Foram incluídos estudos que apresentaram dados ecocardiográficos de pacientes com Covid-19. Características demográficas, doença cardiovascular (DCV) prévia, e achados ecocardiográficos foram extraídos dos estudos. Realizamos uma metanálise de proporções para estimar os principais achados ecocardiográficos. O nível de significância foi p<0,05. RESULTADOS: Do total de 11 233 estudos, 38 preencheram os critérios de inclusão e foram incluídos na metanálise. A proporção estimada de disfunção sistólica do ventrículo esquerdo (VE) foi 25% (IC95%: 19, 31; I2 93%), strain longitudinal global anormal 34% (IC95% 23, 45; I2 90%), disfunção sistólica do ventrículo direito (VD) 17% (IC95% 13, 21; I2 90%), derrame pericárdico 17% (IC95%: 9, 26; I2 97%), e hipertensão pulmonar 23% (IC95%: 15, 33, I2 96%). Disfunção sistólica do VE foi diretamente associada com prevalência de ecocardiograma anormal prévio nos estudos (p<0,001). A proporção de pacientes em ventilação mecânica, indicando gravidade da doença, não explicou a heterogeneidade nas proporções de disfunção do VE (p=0,37). CONCLUSÃO: Entre os pacientes internados com Covid-19, a disfunção ventricular esquerda foi descrita em um quarto dos pacientes, com menores proporções de disfunção do ventrículo direito, derrame pericárdico e hipertensão pulmonar. No entanto, houve uma proporção mais alta de disfunção do VE nos estudos que relataram presença de doença cardíaca prévia, sugerindo que a disfunção cardíaca era predominantemente pré-existente.

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.

The coronavirus disease 2019 (COVID-19) pandemic is a huge challenge to the health system because of the exponential increase in the number of individuals affected. The rational use of resources and correct and judicious indication for imaging exams and interventional procedures are necessary, prioritizing patient, healthcare personnel, and environmental safety. This review was aimed at guiding health professionals in safely and effectively performing imaging exams and interventional procedures.
