Abstract

Background. The effect of cardiovascular risk factors (CVRs) and thrombophilic defects on the risk of arterial cardiovascular complications in patients with prior venous thromboembolism (VTE) is unclear. Objective. We investigated whether the risk of arterial cardiovascular complications is increased after VTE and whether CVRs and thrombophilic defects influence this risk.Methods. Subjects were selected from three family cohorts of probands with VIE or arterial cardiovascular complication before the age of 50 and thrombophilic defects (i.e. hyperhomocysteinaemia, prothrombin G20210A or elevated FVIII). For this analysis, probands with arterial cardiovascular complications before inclusion and their relatives as well as relatives without the studied thrombophilic defects were excluded. We calculated the incidence of arterial cardiovascular complications (e.g. myocardial infarction, ischaemic stroke, transient ischaemic attack or peripheral arterial disease) in subjects with and without VIE and adjusted the relative risk for at least one CVR, two or more thrombophilic defects and quintiles of a propensity score (considering risk factors conditional to VTE history).Results. 861 subjects were included, of whom 399 had experienced VIE before inclusion. Twelve arterial cardiovascular complications occurred in subjects with and nine in subjects without VIE history. Hence the annual incidence was 1.0 (95% CI 0.5 to 1.7) and 0.7 (0.3 to 1.2) in subjects with and without VIE (RR 1.5, 0.6 to 3.6). Adjusting for possible confounders did not change this relative risk.Conclusion. The mildly elevated risk of arterial cardiovascular complications in patients with prior VTE appears to be independent of cardiovascular risk factors and thrombophilic defects.
