Summary

Young women have an increased risk of venous thromboembolism (VTE) during hormonale exposure (estrogen-containing pill or pregnancy). In order to detect women at higher risk of VTE during hormonal exposure, thrombophilia testing is often performed in order to adapt contraception methods and/or to increases thromboprophylaxy during pregnancy. However, such practice is probably not accurate nor discriminent. Indeed, there are evidence that the impact of the familial history of VTE might be stronger than that of detectable inherited thrombophilia.

The "FIT-H" study is a cross-sectional study comparing the prevalence of previous venous thromboembolism in first-degree relatives of women (propositi) who had a first episode of venous thromboembolism in association with hormonal exposure with the prevalence of previous venous thromboembolism in first-degree relatives of women who did not have venous thromboembolism during a similar hormonal exposure.

The primary objective is to determine the association between the presence or the absence of VTE in young women during hormonal exposure and the presence or the absence of a previous episode of VTE in their first-degree relatives. Secondary objective is to determine the impact of associated inherited thrombophilia on the risk of VTE in first-degree relatives.
