Abstract OBJETIVO: Avaliar a existência de associação independente entre a presença de efeito de contraste espontâneo na aorta e eventos isquêmicos encefálicos recentes. MÉTODOS: Estudados com ecocardiograma transesofágico 224 indivíduos com diagnóstico de eventos isquêmicos encefálicos recente 5 e 85 controles que realizaram o exame por diversas doenças cardíacas presentes/suspeitas, sendo pesquisado a presença do efeito de contraste na aorta e de outras potenciais fontes emboligênicas cardíacas associadas. Um questionário sobre os fatores de risco clínicos para eventos isquêmicos encefálicos foi coletado no momento do exame. RESULTADOS: O efeito de contraste na aorta apresentou associação com eventos isquêmicos encefálicos (RC=2,83; IC 95%, 1,65-4,46; P<0,001), na análise bivariada. Na análise multivariada, permaneceu associado a eventos isquêmicos encefálicos recentes (RC=2,05; IC 90%, 1,10-3,85 ; P=0,06). A idade > 60 anos, história de hipertensão arterial sistêmica, história de tabagismo e de dislipidemia foram fatores de risco associados independentemente ao efeito de contraste na aorta. A presença de efeito de contraste espontâneo no átrio esquerdo e a de excrescências de Lambl foram fatores ecocardiográficos associados independentemente ao efeito de contraste na aorta. CONCLUSÃO: O efeito de contraste na aorta esteve associado, de forma independente, aos eventos isquêmicos encefálicos recentes, bem como seus fatores de risco clínicos. Estes resultados vêm reforçar a hipótese de que o fenômeno é um marcador de múltiplos fatores de risco.
