  1. ASTEROID AStudy To evaluate the Effect of Rosuvastatin On Intravascular ultrasound- Derived coronary atheroma burden

  2. ASTEROID: Background and hypothesis • Aggressive lipid modification has demonstrated regression and/or reduced progression of stenotic lesions by quantitative coronary angiography • IVUS trials have shown a halting of progression of atherosclerosis during statin treatment; however, none have provided convincing evidence of regression • Does very aggressive statin treatment with rosuvastatin 40 mg, designed to simultaneously  LDL-C and  HDL-C, result in regression of coronary atherosclerosis? Nissen SE et al. JAMA. 2006;295:1556-65.

  3. ASTEROID: Study design Multicenter, open-label, blinded end point IVUS assessment at baseline and study end Angiographic CAD (>20% luminal narrowing*) Statin-naive N = 507 Rosuvastatin 40 mg qd for 24 months Completed trialN = 349 • Primary efficacy parameters: • Change in % atheroma volume of target vessel • Change in total atheroma volume in most diseased 10-mm segment *Patients with >50% luminal narrowing were excluded Nissen SE et al. JAMA. 2006;295:1556-65.

  4. ASTEROID: Baseline characteristics N = 349 Nissen SE et al. JAMA. 2006;295:1556-65.

JAMA. 2006;295:1556-65.

  11. ASTEROID: Summary • Aggressive statin treatment with rosuvastatin (40 mg) achieved significant changes in lipid levels • LDL-C lowered to 60.8 mg/dL (53.2%) • HDL-C raised to 49 mg/dL (14.7%) • These changes were associated with significant regression of coronary atherosclerosis assessed via prespecified IVUS end points • Benefits were also observed in all prespecified subgroups (including age, sex, BMI, history of diabetes) Nissen SE et al. JAMA. 2006;295:1556-65.

  12. ASTEROID: Implications • Aggressive lipid-modulating strategies in patients with CAD can reverse the atherosclerotic disease process • Therapies designed to simultaneously lower LDL-C while raising HDL-C have the potential to substantially reduce atheroma burden Nissen SE et al. JAMA. 2006;295:1556-65.Blumenthal R et al. JAMA. 2006;295:1583-4.
