Resumo

Resumo: Contexto: As tomografias de tórax são frequentemente solicitadas como exames complementares para avaliação de suspeita clínica de afecção pulmonar pelo novo coronavírus 19 (COVID-19).

Objetivos: Nosso objetivo foi analisar a prevalência dos achados cardiovasculares incidentais em tomografias de tórax solicitadas para avaliar sinais radiológicos sugestivos de COVID-19.

Métodos: Por meio de um estudo transversal, descritivo e retrospectivo, foram revisadas 1.444 tomografias de tórax realizadas no setor de radiologia do Hospital de Clínicas Gaspar Vianna, no período de 1° de março a 30 de julho de 2020, com a descrição da prevalência de imagens sugestivas de pneumonia viral pelo COVID-19, além de achados pulmonares e cardiovasculares incidentais.

Resultados: A média de idade dos pacientes foi 50,6±16,4 anos, sendo o sexo feminino o mais frequente. A tomografia sem contraste foi o método mais utilizado (97,2%), e opacidades em vidro fosco foram identificadas em 56,0% dos casos. Achados incidentais cardiovasculares ocorreram em 51,2% (intervalo de confiança 48,7%-53,8%) das tomografias, prevalecendo calcificação da parede aórtica (21,8%), cardiomegalia (10,5%), e calcificação coronária (5,0%). Nas tomografias com contraste, evidenciaram-se aneurismas de aorta (9,7%), dissecção de aorta (7,3%) e úlceras de aorta torácica (2,4%).

Conclusões: Achados cardiovasculares incidentais ocorreram em aproximadamente metade das tomografias de tórax de pacientes com suspeita de COVID-19, mais especificamente, calcificações da parede da aorta, cardiomegalia e calcificação coronária.
