La importancia de la detección de viabilidad miocárdica en la toma de decisiones en miocardiopatías dilatadas avanzadas isquémico-necróticas Luis Castro Juan Erriest Jorge Camilletti Medicina SPECT Enfermedad coronaria Viabilidad miocárdica Tomografía por emisión de positrones La insuficiencia cardíaca es la primera causa de discapacidad y muerte, que afecta a más de cinco millones de individuos en los Estados Unidos. La morbilidad de esta patología está dada por hospitalizaciones recurrentes, lo que eleva los costos en salud. Los nuevos tratamientos para la insuficiencia cardíaca han mejorado los resultados; pero a pesar de ello, la mortalidad continúa siendo elevada. Debido a que el riesgo operatorio de la cirugía de re- vascularización es alto en los pacientes con disfunción ventricular izquierda y el beneficio de la misma no siempre está asegurado, la estratificación del riesgo no-invasiva para definir la existencia de miocardio viable es esencial. La detección de miocardio viable en pacientes con enfermedad coronaria y disfunción ventricular izquierda (con estudios de perfusión SPECT o con imágenes metabólica con FDG) es considerada una recomendación clase I (nivel de evidencia B). La disfunción ventricular izquierda en la cardiopatía isquémica puede ser debida a tejido fibrótico, necrótico o a tejido viable que puede estar atontado o hibernado. Aproximadamente el 70% de la causa de insuficiencia cardíaca es la enfermedad coronaria, y un número significativo de estos pacientes tienen miocardio hibernado. 2009 artículo científico 1850-1044 https://www.redalyc.org/articulo.oa?id=321927787010 es http://www.redalyc.org/revista.oa?id=3219 INSUFICIENCIA CARDIACA application/pdf Federación Argentina de Cardiología INSUFICIENCIA CARDIACA (Argentina) Num.4 Vol.4
