  Purpose
The central hypothesis for this work is that platelet - leukocyte interactions play a critical role in the pathogenesis of acute ischemic events. The primary objective of the study is to determine if early, high-dose administration of the HMG-CoA reductase inhibitor rosuvastatin in the setting of acute coronary syndrome and percutaneous coronary intervention exerts beneficial vascular effects by reducing platelet - leukocyte interactions.

Primary Outcome Measures:
  • Platelet - Leukocyte Aggregates [ Time Frame: within first 24 hours ]
    measured by flow cytometry


Secondary Outcome Measures:
  • Biomarkers of Platelet Function and Myocardial Necrosis [ Time Frame: up to 30 days ]

Enrollment: 54
Study Start Date: June 2011
Study Completion Date: February 2014
Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Crestor Drug: rosuvastatin
Patients (n = 54) presenting acute coronary syndrome/non-ST elevation myocardial infarction who present within 8 hours of symptom-onset will be randomized to two groups to receive rosuvastatin (40 mg oral dose) or placebo at the time of presentation, in addition to standard of care (aspirin, clopidogrel, low molecular weight heparin). Blood will be collected at baseline (time of enrollment, immediately prior to drug or placebo), at 6 - 8 hours, at 18 - 24 hours, and at 30 days for analysis of platelet - leukocyte co-aggregate formation, biomarkers of platelet - leukocyte interactions, and biomarkers of myocardial necrosis. Additional samples may be collected just after revascularization, in patients undergoing PCI. The group of patients treated with rosuvastatin will be maintained on rosuvastatin 20 mg daily and the group randomized to placebo will be given rosuvastatin (20 mg oral once daily) within 48 hoursof enrollment and after planned PCI, but before hospital discharge.
