RELATION OF HEART CASES TO BODY WEIGHT Having learned that in these cases there was no history of cardiac involvement from disease, J thought it might be of interest to search for other causative factors. We have studied the age, height and weight of these contestants and classified them as over, under and normal weight. The relation of these heart cases to the body weight is shown in Table 12.
