Cardiovascular disease and mortality after a first episode of venous thromboembolism in young and middle-aged women

• Background: Patients with a history of venous thromboembolism (VTE) seem to have an increased risk of arterial cardiovascular disease (CVD). Objectives: To evaluate the risk of CVD and overall mortality after a first episode of VTE in women and to assess common risk factors for VTE and CVD. Patients/methods: We performed a cohort study inviting 1433 women with a previous VTE (exposed) and 1402 women without VTE (unexposed). The cohort was derived from TEHS, a Swedish population-based case-control study on risk factors for VTE in women age 18-64 years. The women were recruited in 2002-2009. During 2011 information on CVD and mortality was obtained from a questionnaire and from the Swedish Patient Register and the Cause of Death Register. Hazard ratios (HR) for CVD and their 95% confidence intervals (CI) were calculated using Cox regression. In multivariate analyses we adjusted for age, smoking, diabetes mellitus, hypertension and body mass index. Results: 2108 (75%) women (mean age 47 +/- 13 years) accepted participation. During the total follow up of 11,920 person years 35 (3.2%, 95% CI 0.7-2.1) among the exposed and 14 (1.4%, 95% CI 0.2-4.3) among the unexposed had any CVD event. The adjusted HR for CVD was 2.0 (95% CI 1.1-3.9) the adjusted HR for mortality was 2.3 (95% CI 1.2-4.6) Conclusion: Women with a previous VTE had a two-fold increased risk of CVD and overall mortality. Adjusting for cardiovascular risk factors only modestly changed the estimates.
