[The secretory type of persons who have survived a myocardial infarct]
250 persons (117 men and 73 women) with past myocardial infarction, between 19 and 65 years of age, were examined for the secreting quality (or nonsecreting) of ABO(H) antigens in the saliva. The secreting persons were additionally examined for the antigens titer. 38.40% of the persons examined were found to be nonsecreting which is twice as many than are normally found among the Bulgarian population (18.69%). In the group of patients with past myocardial infarction the weak secreting persons were significantly more numerous while the moderate and strong secreting persons were significantly less. The data of the study allow the conclusion that the nonsecreting and the hyposecreting types are a risk factor for myocardial infarction.
