Limitaciones del blush miocárdico para el análisis de la perfusión miocárdica en pacientes con infarto agudo de miocardio y flujo TIMI 3
Introduccion y objetivos Analizamos la variabilidad en la medicion del indice angiografico de blush entre un hospital universitario y un laboratorio central independiente, asi como su correlacion con la perfusion analizada mediante ecocardiografia miocardica con contraste intracoronario (EMC) y con la funcion ventricular a los 6 meses Metodos Se incluyo en el estudio a 40 pacientes con un primer infarto agudo de miocardio con elevacion del segmento ST, enfermedad de un vaso y arteria relacionada con el infarto abierta. La perfusion se cuantifico por angiografia (mediana quinto dia, rango de 3-7) mediante el blush miocardico en nuestro laboratorio y en un laboratorio central independiente. S…
Limitations of Myocardial Blush Grade in the Evaluation of Myocardial Perfusion in Patients With Acute Myocardial Infarction and TIMI Grade 3 Flow
Introduction and objectives An analysis was made of variability in the measurement of the angiographic index blush between a university hospital and an independent core laboratory, as well as its correlation with perfusion analised by intracoronary myocardial contrast echocardigraphy (MCE) and the ventricular function at the sixth month. Methods The study comprised 40 patients with a first ST-segment elevation myocardial infarction, single-vessel disease and open infarct-related artery. Perfusion was quantified by angiography (median fifth day, range 3-7) with blush in our laboratory and in an independent core laboratory. MCE was performed. Ejection fraction at the sixth month was determine…
