La granulomatosis eosinofílica con poliangeítis, anteriormente conocida como síndrome de Churg-Strauss, es una patología poco frecuente que pertenece al grupo de enfermedades caracterizadas por vasculitis necrotizante de vasos sanguíneos sistémicos de pequeño y mediano calibre. La afectación cardiovascular sintomática ocurre entre un 27% a un 47% de los casos de Churg-Strauss, siendo una de las manifestaciones más graves. El diagnóstico suele confirmarse con biopsia de tejido con infiltración de eosinófilos, pero con la reciente inclusión de la resonancia cardíaca, podemos prescindir de ella.
El diagnóstico precoz es importante debido a que el tratamiento oportuno suele asociarse con mejoría del cuadro.
Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome, is a rare pathology that belongs to a group of diseases characterized by necrotizing vasculitis of small and medium-sized systemic blood vessels. Symptomatic cardiovascular involvement occurs in 27%–47% of cases of EGPA and is one of the most severe manifestations. The diagnosis is usually confirmed by eosinophilic infiltration observed in tissue biopsy, but with the recent inclusion of cardiac magnetic resonance imaging (MRI), the former can be replaced. Early diagnosis is important because timely treatment is often associated with improvement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
