| Abstract: | Several epidemiological studies have demonstrated at the individual level an elevated risk of cardiovascular death for women who have been using oral contraceptives. Nevertheless, there has been no detectable increase in the number of cardiovascular deaths during the last fifteen years in countries where the use of oral contraceptives has become widespread. In this paper, we have tried to analyse this apparent contradiction and to discuss the causal nature of the relationship linking oral-contraceptives and cardiovascular death. For this purpose, we present a bibliographical summary of the relevant studies as well as an analysis of the trend in cardiovascular deaths among women in France from 1968 to 1975. |
