Based on moderate quality evidence , due to concerns about risk of bias and imprecision , initiation of statin therapy within 14 days following ACS does not reduce death , myocardial infa rct ion , or stroke up to four months , but reduces the occurrence of unstable angina at four months following ACS .
Serious side effects were rare
BACKGROUND The early period following the onset of acute coronary syndrome ( ACS ) represents a critical stage of coronary heart disease , with a high risk of recurrent events and deaths .
The short-term effects of early treatment with statins on patient-relevant outcomes in patients suffering from ACS are unclear .

Effects of 4 weeks of atorvastatin administration on the antiinflammatory cytokine interleukin-10 in patients with unstable angina.
Atherosclerosis is currently considered a chronic inflammatory disease of the vessel wall . Systemic markers of inflammation have been shown to be of significant prognostic relevance for assessing the risk of atherosclerotic disease progression (1)(2)(3)(4 ) . Previous data showed that proinflammatory markers , such as C-reactive protein ( CRP ) , play an important role in acute coronary events (5)(6)(7 ) and that decreased plasma concentrations of antiinflammatory cytokines , for example , interleukin-10 ( IL-10 ) were also associated with acute coronary syndrome ( ACS ) (8)(9)(10 ) . Statins , 3-hydroxy-3-methyglutaryl-coenzyme A reductase inhibitors , represent a well-established class of drugs that effectively lower serum cholesterol concentrations and are widely used for the treatment of cardiovascular disease (11)(12)(13 ) . In addition to their cholesterol-lowering activity , statins have been demonstrated to possess pleiotropic effects , including antiinflammatory effects (14)(15)(16)(17 ) . Results obtained in numerous investigations have suggested that administration of statins could modify concentrations of CRP and other proinflammatory cytokines with a concurrent decrease in cardiovascular events . However , the potential influence of statins on the antiinflammatory cytokine IL-10 in patients with ACS has not been investigated . In the present study , 42 patients with unstable angina ( UA ) were r and omly assigned immediately after admission to st and ard therapy  plus either 20 mg/day atorvastatin or placebo . The st and ard therapy included aspirin , beta-blockers , heparin/low – molecular-weight heparin , angiotensin-converting enzyme inhibitors , and oral nitrates . The protocol s of the study were approved by the Ethics Review Board of the Hospital , and all patients gave written , informed consent . The patients with UA presented with  ischemic chest pain  at rest in the absence of extracardiac cause with ST-segment depression ≥0.1 mV in 2 or more contiguous leads on 12-lead electrocardiograms at administration . Echocardiography was performed in all patients to exclude patients with an impaired left
