| Summary: | O peso do coração é menor nos chagásicos com "megas" do que nos falecidos subitamente ou em I.C.C., sendo, porém, maior que nos controles. Já o peso corporal ésemelhante nos chagásicos falecidos subitamente e nos controles, havendo redução moderada no grupo com I.C.C., e rtiais acentuada nos chagásicos com "megas" (redução de 20% em relação aos controles). A relação percentual peso cardíaco/peso corporal é de 1,1% no grupo com I.C.C.; 0,71% no grupo de morte súbita; 0,77% no grupo com "megas"; 0,49% no grupo controle e 0,60% ne grupo de doenças caquetizantes. Com base nas médias dos pesos cardíacos e corporal dos grupos controle, de doenças caquetizantes e de megas, calculou-se que o emagrecimento ocorrido nos megas reduziria o peso cardíaco médio de apenas 6,8%. Heart weight is less in chagasic patients with "mega" syndromes than in those which have died suddenly or with congestive heart failure, it is, however, greater than in the Controls. Body weight is similar in chagasic patients who have died suddenly and in the Controls, there is a moderate body weight reduction in the group with congestive heart failure, and a more accentuated reduction in chagasic patients with "mega" syndromes (a reduction of 20% in comparíson with the Controls). The relationship between heart - weight and body - weight, expressed as a percentage is 1,1% in the group with congestive heart failure; 0,71% in the group which died suddenly; 0.77% in the group with "mega" syndromes, 0.49% in the Controls group and 0.60% in the group with cachexia producing diseases. On the basis of mean heart - weights and body - weights of the control group, group with cachexia producing diseases and group with "mega" syndromes it was calculated that the emaciation which occurred in those with "mega"syndromes could reduce mean heart - weight by at least 6.8%.
