title: Early pharmacologic intervention and plaque stability in acute coronary syndromes.
abstract: Remarkable therapeutic advances in the treatment of acute coronary syndromes (ACS) have been made with antiplatelet and antithrombotic therapy. However, these therapies alone do not appear to completely stabilize culprit lesions. Evidence from a variety of sources suggests that intensive cholesterol lowering with statins favorably influences culprit lesion stabilization in patients with ACS. Potential mechanisms of benefit include improvements in endothelial function, decreased propensity for platelet thrombus formation, and reduction in inflammation at the site of the lesion. The Myocardial Ischemia with Aggressive Cholesterol Lowering (MIRACL) study is the first large-scale clinical trial to examine whether these mechanisms translate into clinical-event reduction in patients with ACS as well as the substantial proved benefits in the chronic coronary syndromes. In this trial, early initiation of atorvastatin after an episode of unstable angina or non-Q-wave myocardial infarction reduced events over the ensuing 16 weeks. It is hoped that a growing awareness of the benefits of early statin therapy to stabilize culprit lesions in ACS will lead to an increase in the proportion of coronary patients who will receive this beneficial therapy.
