RESUMO
Um marcador prognóstico estrutural se faz necessário nas miocardiopatias dilatadas. Estudamos, por biópsia endomiocárdica e ecocardiograma, indivíduos normais (C) e com miocardiopatia dilatada idiopática (MCDI) e chagásica (MCDC). Avaliamos a relação entre a quantidade de colágeno (FVCI) e a sobrevida, se a FVCI diferia entre as etiologias e se ela interferia na função miocárdica. A FVCI foi maior nos miocardiopatas e não diferiu entre eles (MCDC= 6,83 5,47; MCDI = 5,75 4,45; C= 0,42 0,14* p<0,001). Ela não correlacionou com sobrevida e na MCDI a fração de ejeção do ventrículo esquerdo (FEVE) teve relação com a FVCI/A structural prognostic marker is needed regarding dilated cardiomyopathy. We studied, by endomyocardial byopsies and 2D-echocardiogram, normal patients (C) and with idiopathic and chagasic dilated cardiomyopathy (IDC, CDC). We evaluated the correlation between myocardial collagen (ICVF) and the survival rate, the difference between the two etiologies and it correlation with myocardial function. The ICVF was higher in the cardiomyopathy groups but did not differ between them (CDC= 6,83 5,47; IDC= 5,75 4,45; C= 0,42 0,14* p<0,001). The ICVF did not correlate with survival rate and in IDC it correlated with left ventricular ejection fraction...
