|Abstract:||AIMS: Statins can inhibit the progression of coronary atherosclerosis. We aimed to characterize clinical factors that associate with differing measures of coronary atheroma volume following potent statin therapy. METHODS AND RESULTS: SATURN employed serial intravascular ultrasound (IVUS) to monitor changes in measures of coronary atheroma burden [total atheroma volume (TAV) and per cent atheroma volume (PAV)] in 1039 patients with coronary artery disease, treated with rosuvastatin (40 mg) or atorvastatin (80 mg) daily for 24 months. Rosuvastatin-treated patients demonstrated greater reductions in low-density lipoprotein cholesterol (LDL-C, 47 vs. 40%, P < 0.001) and greater increases in high-density lipoprotein cholesterol (HDL-C, 13 vs. 10%, P = 0.02). These alterations in the lipid profile associated with greater TAV (−6.4 vs. −4.4 mm3, P = 0.01), but not PAV (−1.22 vs. −0.99%, P = 0.17) regression. Greater TAV reductions with rosuvastatin vs. atorvastatin occurred in patients with diabetes (P = 0.01, treatment by diabetic status interaction P-value 0.05). Greater PAV reductions with rosuvastatin were evident in females (P = 0.01, treatment by sex interaction P-value 0.03) and in those with greater than or equal to median baseline LDL-C (P = 0.02, treatment by LDL-C group interaction P-value 0.03) or HDL-C levels (P = 0.02, treatment by HDL-C group interaction P-value 0.04). On multivariable analysis assessing change in TAV and PAV, both higher baseline TAV and PAV independently associated with TAV and PAV regression, respectively (standardized estimates: TAV −0.25, P < 0.001; PAV −0.23, P < 0.001). CONCLUSION: Higher-risk patients, particularly those with greater baseline coronary atheroma volume, are more likely to experience less disease progression with potent statin therapy.|
