It is not known whether PPAR-alpha agonist gemfibrozil is able to exert rapidly its lipid modulating, potential antiinflammatory and antithrombotic effects in patients with non-ST elevation acute coronary syndrome (NSTEACS), as some other lipid lowering drugs e.g. statins do. We randomized 44 patients with NSTEACS to open gemfibrozil (n=22, 600 mg b.i.d for 90 days) or no gemfibrozil (controls, n=22) within 24 hours after pain onset. Semiquantitative C-reactive protein (CRP) latex test was used at baseline for exclusion of patients with overt inflammation. All patients received dalteparin or enoxaparin for >48 hours and oral aspirin (125 mg/day) and were treated noninvasively. Lipids, high sensitive CRP, soluble CD40 ligand (CD40L) and von Willebrand factor (vWF) activity were assessed on days 1 (baseline), 4, 7, 14, 30 and (except CD40L) 90. Gemfibrozil use was associated with significant lowering of triglycerides by day 30, however it did not prevent acute significant decline of high density lipoprotein cholesterol (HDL-C), which was similar in both groups. CD40L level significantly increased while CRP levels decreased by day 30 in both groups. Moreover, selection of a subgroup with baseline HDL-C <1.0 mmol/l did not reveal any difference in changes of CRP or CD40L between gemfibrosil treated and control patients. vWF activity did not change in controls and significantly increased in gemfibrozil group by days 7, 14, but from lower baseline level. In patients with NSTEACS early administration of gemfibrozil was not associated with positive changes of CRP and CD40L levels or vWF activity compared with control group.
