ABSTRACT
BACKGROUND: Beneath its lipid-lowering properties additional non-lipid effects of statin therapy are discussed. We therefore examined the impact of statins on laboratory markers of coagulation, inflammation and soluble cell adhesion to further explore these effects in 950 hospitalised patients with angiographically proven CAD. METHODS AND RESULTS: Although no significant differences were found in total cholesterol, LDL and HDL and triglyceride levels a statistically lower value in 277 statin-treated patients was found for von Willebrand factor [162(130/224) vs. 208(154/283)%, P=0.0001], leukocyte count [6.9(5.8/8.4) vs. 7.3(6.1/9.4)/nl, P=0.0005], high sensitive CRP [4.3(1.8/10.8) vs. 7.6(2.8/20.0) mg/dl, P=0.0001], interleukin-6 [9.5(5.1/18.7) vs. 14.4(7.2/28.1) mg/dl, P=0.0001] and soluble p-selectin [112.6(82.0/146.0) vs. 127.8(93.8/162.4) mg/dl, P=0.001] compared to 673 patients without statin therapy. This result was confirmed in a subgroup of 510 patients matched for age, gender and percentage of acute coronary syndromes. CONCLUSIONS: In statin treated patients significantly lower levels of coagulation, systemic inflammation and soluble cell adhesion markers were found. Therefore the effect of statin therapy may also be mediated by additional non-lipid-lowering effects.
