Abstract
The incidence of malignant disease in an autopsy series of 643 subjects over 30 years of age was studied. Of this number, 244 cases suffered from coronary heart disease, and in 399 the disease was absent. The difference between the incidence of malignant disease in these two groups was tested statistically.
When men and women were taken together, there was highly significantly less malignant disease in the group with coronary heart disease than in the group without it. Similarly, when men and women were treated separately, in both cases those with coronary heart disease had significantly less malignant disease than those without it.
When the cases were divided into age groups (30-49, 50-64, 65-80, and over 80 years of age), with men and women taken separately, there were no statistical differences in the frequency of malignant disease when compared with the incidence of coronary heart disease in each group. When men and women together were divided into age groups, there was significantly less malignant disease in the age group of 50-64 years among the subjects with coronary heart disease than without it.
