“…The relationship between the heart and lung changes is uncertain. That the combination is fortuitous is unlikely, since the association of idiopathic pulmonary haemosiderosis with a myocarditis or myocardial abnormality other than cor pulmonale has been reported in at least nine other subjects in the past (Gellerstedt, 1939;Glanzmann and Walthard, 1941 ;Scheidegger and Dreyfus, 1945;Wigod, 1955;Soergel, 1957;Campbell and Macafee, 1959;Saltzman, West, and Chomet, 1962;Murphy, 1965). Nor is it likely that the pulmonary changes are secondary to cardiac damage, as pulmonary haemosiderosis similar to that found with severe mitral stenosis or prolonged left ventricular failure has not, so far as the authors are aware, been reported with other cardiac abnormalities.…”
