RESUMEN
Debido a la importancia que posee la cuantificación precisa del tamaño del infarto miocárdico (IM), se estudió la concordancia entre su tamaño determinado mediante cintigrafía miocárdica SPECT utilizando un programa de cuantificación automático independiente del operador y Ecocardiografía bidimensional, en 24 pacientes con antecedentes de IM antiguo (más de 1 mes). Los IM se dividieron en 3 categorías grandes, medianos y pequeños. Se obtuvo concordancia estadísticamente significativa, aunque de grado moderado, entre ambas técnicas. Concluimos que el método cintigráfico asociado a este programa de cuantificación automático se compara bien a la Ecocardiografía, con la ventaja para el primero de ser operador independiente. Es posible que el grado de concordancia hubiese podido ser incluso mayor, si se hubiese usado en Ecocardiografía análisis con doppler tisular en forma sistemática.
ABSTRACT
Due to the importance of an accurate quantification of the myocardial infarction size, we studied the agreement between its magnitude as determined by gated SPECT with an automatic quantification program and echocardiography, in 24 patients with history of old MI (more than 1 month). The myocardial infarctions were divided into 3 categories great, medium and small. Statistically significant agreement was obtained, although of moderate degree, between both techniques. We conclude that the nuclear method associated to this program of automatic quantification is compared well to echocardiography, with the advantage for the first one of being independent operator. It is possible that the agreement degree could have been even better, if systematic analysis with tissue Doppler had been performed during echocardiography.
