Infarto agudo do miocárdio por dissecção espontânea de artérias coronárias: série de cinco casos

Abstract: Relatamos série de 5 pacientes internados por síndrome coronária aguda, entre 2008 e 2010, nos quais a cinecoronariografia evidenciou dissecção coronária espontânea. A dissecção coronária espontânea é uma causa rara de infarto do miocárdio, mais comumente observada em indivíduos jovens e sem histórico de doenças cardiovasculares. O manejo ideal é incerto, principalmente pela limitada experiência clínica com essa entidade. A ultrassonografia intracoronária é uma ferramenta útil tanto para o diagnóstico da disse… Show more

“…The IVUS may also contribute to guide the percutaneous treatment whenever necessary. 4 In fact, the use of intracoronary images, through IVUS or OCT, allows better visualization of the structure and composition of the coronary wall, allowing the evaluation of the intramural hematoma, as well as the differentiation between the true and the false lumens. 3 The IVUS was performed in one of the reported cases, demonstrating an image compatible with SCAD.…”

“…1 Frequentemente subdiagnosticada em sua história, a DEAC representa de 5 a 10% dos infartos do miocárdio e são mais frequentes em mulheres jovens sem eventos cardiovasculares. [2][3][4] Apesar do subdiagnóstico, mais episódios estão sendo identificados devido à investigação mais ampla e aos avanços em métodos complementares, especialmente os de imagem intracoronária. 3 A suspeita inicia-se quando há manifestações clínicas de dor torácica isquêmica, alterações eletrocardiográficas compatíveis com isquemia miocárdica e, comumente, elevação de marcadores de necrose miocárdica, juntamente com cineangiocoronariografia evidenciando ausências de estenoses significativas, ou seja, estenoses de até 50% da luz do vaso.…”
