Summary, in English

Background: The value of parental history as a risk indicator for venous thromboembolism (VTE) has not been determined in a nationwide setting. Objectives: This is the first nationwide study of age and sex specific familial VTE risks in offspring of parents hospitalized for VTE. Patients/Methods: The Swedish Multigeneration Register of 0-75-year-old subjects was linked to the Hospital Discharge Register for 1987-2007. Standardized incidence ratios (SIRs) were calculated for individuals whose parents were hospitalized for VTE compared to those whose parents were unaffected. Results: Among 45,362 hospitalized offspring cases with VTE, 4865 offspring of affected parents were identified with a familial SIR of 2.00 (95% CI 1.94-2.05). Familial SIR was slightly higher for male offspring than for female offspring (2.08, 95% CI 2.00-2.16 vs. 1.91, 95% CI 1.84-1.99). The risk in offspring was further increased when both parents were affected (3.97, 95% CI 3.40-4.61), with high familial risks at ages 20-29 years (10.00, 95% CI 5.91-15.84). The familial risks for VTE among offspring were increased from the age of 10 up to 75 years, with a familial SIR of 3.96 (95% CI 3.13-4.94) at ages 10-19 years and 1.48 (95% CI 1.17-1.84) at age 70-75. However, the absolute incidence rate increased with age. Conclusions: Parental history is potentially useful for risk assessments of VTE, although age needs to be considered. Our results support the use of an age-dependent multicausal model to estimate the risk of VTE.
