Association of Traditional Cardiovascular Risk Factors with Venous Thromboembolism: An Individual Participant Data Meta-analysis of Prospective Studies

Circulation

Meta-analysis (9 studies, n=255,865 with 4910 VTE events) found that apart from the association of cigarette smoking with provoked VTE, modifiable traditional CVD risk factors are not associated with increased risk. Higher systolic blood pressure was inversely associated with VTE.

Anticoagulant therapy for symptomatic calf deep vein thrombosis (CACTUS): a randomised, double-blind, placebo-controlled trial

The Lancet

This RCT (n=152) showed no significant difference between patients receiving nadroparin v placebo in the composite primary outcome-composite measure of
extension of calf DVT to proximal veins, contralateral proximal DVT and symptomatic PE at day 42 (3% vs 5% respectively, p=0.54).
