Family history of venous thromboembolism (VTE) and risk of recurrent hospitalization for VTE: a nationwide family study in Sweden.
Data concerning the importance of family history of venous thromboembolism (VTE) for the risk of recurrent VTE are sparse. The aim of this nationwide study was to determine whether family history of VTE is a risk factor for recurrent hospitalization for unprovoked VTE (deep venous thrombosis of the lower extremities or pulmonary embolism).
