Abstract

The use of 3-hydroxy-3-methylglutaryl coenzyme A reductase (statins) is associated with a marked reduction in morbidity and mortality in patients at high cardiovascular risk or with established cardiovascular disease. In the last decade, several randomized controlled studies have demonstrated the benefit of statins in patients with acute coronary syndrome (ACS). These studies showed that use of statins in patients with ACS is associated with a significant reduction of the risk of recurrent cardiovascular events. Current American College of Cardiology/American Heart Association (ACC/AHA) guidelines recommend (Level of Evidence 1A) the use of statin therapy before hospital discharge for all patients with ACS regardless of the baseline low-density lipoprotein. Although there is no consensus on the preferable time of administration of statins during ACS, some clinical trials and pooled analyses provided substantial support for the institution of an early initiation to improve strategies that target the pathophysiologic mechanism operating during myocardial infarction. In particular, recent findings suggested that the earlier the treatment is started after the diagnosis of ACS the greater the expected benefit. Experimental studies with statins in ACS have shown several other effects that could extend the clinical benefit beyond the lipid profile modification itself. In particular, statins demonstrated the ability to induce anti-inflammatory effects, modulate endothelium and inhibit the thrombotic signaling cascade. Given these recognized potential benefit, statins should conceivably modulate the pathophysiological processes involved in the very early phase of plaque rupture and coronary thrombosis.
