Among 3, 146 patients, 1, 591 patients were randomized to a loading dose of statin before PCI and 1, 555 patients were given statin therapy initiated only after the PCI. Statin loading prior to PCI was associated with a 56% relative reduction in pMI (OR: 0.44, 95% CI: 0.35–0.56; <italic>P</italic> < 0.00001). There was a 41% reduction in clinical events in follow‐up in the group of patients treated with statin loading prior to PCI (OR: 0.59, 95% CI: 0.38–0.92, <italic>P</italic> = 0.02). When stratified according to the clinical presentation, the results were only significant for those patients with NSTE‐ACS (OR: 0.18, 95% CI: 0.07–0.47; <italic>P</italic> = 0.0005) and was not noted in the group of patients who underwent PCI for stable angina (OR: 0.92, 95% CI: 0.53–1.61; <italic>P</italic> = 0.78).</p> </sec> <sec id="ccd25302-sec-0005" sec-type="section"> <title>Conclusions</title> <p>High dose statin therapy given prior to PCI in patients with NSTE‐ACS is associated with a reduction in pMI and short‐term clinical events. © 2013 Wiley Periodicals, Inc.</p> </sec> </abstract>
