Síndrome de Wellens Online (Wellens syndrome)

Por Paulo Leite 12/03/2019

¨Descrita pela primeira vez em 1982. a síndrome de Wellens é incomum na prática médica. Constitui apresentação de síndrome coronariana aguda (SCA) de alto risco e está associada à estenose grave da porção proximal da artéria coronariana descendente anterior. Tal condição clínica se não identificada e tratada precocemente, pode evoluir para infarto agudo do miocárdio em parede anterior e óbito. Na síndrome de Wellens é observado um fenômeno de inversão da onda T observado nas derivações precordiais do eletrocardiograma nos pacientes com angina instável. Esse achado é visto no estado sem dor. Dois padrões diferentes foram descritos. O tipo A apresenta ondas T bifásicas em V2-V3 e o tipo B apresenta inversões simétricas profundas de onda T em V2-V3. Esta etiologia significa estenose crítica na artéria descendente anterior esquerda (DAE). A síndrome é um estágio pré-infarto de estenose significativa da artéria descendente anterior esquerda (DAE), que pode levar a infarto do miocárdio extenso, da parede anterior, sem intervenção oportuna. Após o diagnóstico exige-se revascularização miocárdica imediata seguida de prevenção cardiovascular secundária. ¨
