It has repeatedly been shown that statins decrease morbidity and mortality in patients with atherosclerosis, thus supporting their use for the primary and secondary prevention of ischemic heart disease. Different pathological pathways that are triggered in the setting of acute coronary syndrome (ACS), such as endothelial dysfunction, activation of inflammatory and coagulation cascades, and thrombus formation, are known to be inhibited by statins, thereby justifying the use of these agents in patients with ACS. Several recent prospective controlled clinical trials have demonstrated the safety and, in some cases, the efficacy of statins when administered early after ACS. An increasing number of publications have reported, however, that statins may confer a beneficial effect not only in early secondary prevention, but also in the direct treatment of ACS (ie, when statins are administered as first-line treatment in clinically unstable patients). This therapeutic option is supported by the following: numerous experimental studies demonstrating a protective effect of statins under conditions of acute ischemia; analysis of different registries and trials, which has demonstrated a more favourable prognosis for statin-treated patients at the time of acute myocardial ischemia; and small clinical trials reporting a lower periprocedural infarction rate during coronary intervention or lower levels of several prognostic biomarkers, in addition to a lower incidence of cardiovascular events associated with statin therapy. Nevertheless, confirmation of this hypothesis in large prospective controlled clinical trials will be necessary before the implementation of statins as first-line therapy in unstable patients with ACS, irrespective of blood cholesterol levels.

BACKGROUND: Intensive statin therapy decreases mortality and incidence of coronary events in patients after acute coronary syndrome (ACS). Recently it has been reported that spontaneous lipid levels remain clinically stable during ACS. The immediate influence of lipid levels by high-dose statin therapy initiated at admission in ACS patients is, however, not clear. METHODS: We have analyzed a group of 114 patients with ACS (mean age 63.7; females 25.4%). Atorvastatin 80 mg was administered at admission and then once daily for the rest of hospitalization. The levels of total cholesterol (TC), LDL-cholesterol (LDL), HDL-cholesterol (HDL), and triglycerides (TG) were measured at admission (D0), and then every morning of hospitalization (D1, D2). RESULTS: The mean entry values (D0) of TC, LDL, HDL and TG (in mmol/L) were 5.24, 3.26, 1.07 and 1.31, respectively. The therapy with atorvastatin 80 mg resulted in a decrease of TC levels in the first morning (D1) by 6.1% and in the second morning (D2) by 13.2% (p<0.001 for all comparisons with the entry value D0); LDL was decreased by 5.8% (D1) and 15.6% (D2) (p<0.001 vs. D0); the level of HDL was decreased by 7.5% (D1) and 12.1% (D2) (p<0.001 vs. D0). In contrast, the TG level was higher in the first morning (D1) by 20.6% and in the following morning (D2) by 25.5% (p<0.05 vs. D0). CONCLUSIONS: We have shown that intensive statin therapy started at admission in ACS patients has a highly significant, immediate effect on all monitored lipid levels. Since TC and LDL levels were decreased as predicted, reduction in HDL and increase in TG levels suggest a different acute effect of high-dose statin on lipid levels in comparison with long-term treatment of ACS patients.
