Abstract
Two epidemiologic studies carried out in the United Kingdom suggest that oral contraceptives increase the risk of myocardial infarction.1 , 2 Mann and Inman1 studied 153 women less than 50 years of age who died of myocardial infarction together with controls matched for age and marital status who were under the care of the same general practitioners. There was a significant association between oral contraceptive use and myocardial infarction (P < 0.001). This association became stronger with increasing age: the relative risks for the groups 30 to 39 years and 40 to 44 years of age were 2.8 and 4.7, respectively. Hypertension . . .
