IgM and IgG anti-milk antibodies measured by radioimmunoassay in myocardial infarction.

Antibodies against milk protein were sought by a radioimmunoassay in 47 patients with myocardial infarction and in 50 control patients. There was no difference between the two groups in the frequency or in the quantity of IgM and IgG antibodies against milk proteins. These results do not support the suggestion that anti-milk antibodies are involved in the pathogenesis of coronary heart-disease.
