Lipid parameters, lipid lowering drugs and the risk of venous thromboembolism.

Abstract : BACKGROUND: Besides their effects on atherogenesis, lipids and lipoproteins could contribute to the development of venous thromboembolism (VTE). This association has been investigated in a few studies with conflicting results. METHODS: Plasma levels of total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, apolipoprotein A-I and apolipoprotein B were measured in 467 patients with a first unprovoked VTE event diagnosed between May 2000 and December 2004 and in 467 age and sex matched controls. The association between these parameters and VTE was determined in non-users of lipid lowering drugs (LLD), in statin users and in fibrate users in a quartile-based analysis. We repeated this stratified analysis within each stratum of men and women. RESULTS: The median age of patients was 73 years [interquartile range 58-80], 41.5% were men. Among the 934 patients of the study, 100 were treated with statin, 91 with fibrate and 743 were not receiving LLD. Among non users of LLD, high levels of apolipoprotein B were associated with VTE (OR 1.82, 95% CI 1.19-2.79) after adjustment for age and body mass index. Elevated LDL-cholesterol levels were associated with VTE only in men (OR 2.32, 95% CI 1.07-5.01). High levels of LDL/HDL-cholesterol and apolipoprotein B/apolipoprotein A-I ratios were associated with VTE (OR 2.76, 95% CI 1.69-4.50 and OR 1.86, 95% CI 1.16-2.97 respectively) but this effect was mainly observed in men. There was no association between lipid parameters and VTE in statin users and in fibrate users. CONCLUSION: Our results are in line with the new concept of a global cardiovascular disease combining atherosclerosis and VTE.
