We analysed statistically the association of emphysema, determined on inflation fixed specimens, with the weights of the body and heart, and of the cardiac ventricles, weighed separately, in 170 male and 86 female adult autopsies. The cases were grouped according to the cause of death into cardiovascular, cancer and other deaths. In men the body weight was inversely proportional to the severity of emphysema, but no association existed between the body weight and the cause of death. In male cardiovascular deaths the total heart weight, total ventricular weight and the weight of the left ventricle with the septum were also inversely proportional to the severity of emphysema while this was not true in the other deaths. In male cardiovascular deaths a decrease, and in the other deaths an increase, of the weight of the free wall of the right ventricle was associated with an increasing severity of emphysema. In all male deaths, however, the left to right ratio decreased with an increasing severity of emphysema. Thus, pulmonary emphysema is associated both with a general atrophy, including the myocardium, and a mainly relative right ventricular hypertrophy. An absolute right ventricular hypertrophy, however, seems to accompany emphysema only in the absence of other major cardiovascular diseases. [ABSTRACT FROM AUTHOR] |
