- Abstract
- Background: There are few data regarding the effect of statins on regression and compositional changes of plaque according to the reduction in high-sensitivity C-reactive protein (hs-CRP) levels in acute myocardial infarction (AMI) patients. Methods: We used serial virtual histology-intravascular ultrasound to assess the efficacy of pitavastatin (dosage: 2 mg/day) on plaque regression and compositional changes according to the degree of reduction in hs-CRP levels from baseline to follow-up [>= 1 mg/dl (n = 62) vs. <1 mg/dl (n = 32)] in non-intervened non-infarct related artery in AMI patients who were enrolled in the Livalo in acute myocardial infarction study (LAMIS). Results: Total atheroma and percent atheroma volumes decreased more significantly in patients with reduction in hs-CRP >= 1 mg/dl compared with those with reduction in hs-CRP <1 mg/dl (-1.7 +/- 12.4 mm(3) vs. +2.7 +/- 7.8 mm(3), p < 0.015, and -0.4 +/- 3.4% vs. +0.4 +/- 4.8%, p < 0.001, respectively). Absolute and %necrotic core volumes decreased more significantly in patients with reduction in hs-CRP >= 1 mg/dl compared with those with reduction in hs-CRP <1 mg/dl (-0.4 +/- 3.5 mm(3) vs. +1.9 +/- 3.4 mm(3), p = 0.038, and -1.1 +/- 4.9% vs. +2.7 +/- 4.7%, p = 0.016, respectively). Reduction in hs-CRP >= 1 mg/dl at follow-up was the independent predictor of reduction of percent atheroma volume and %necrotic core volume at follow-up [odds ratio (OR), 2.228; 95% confidence interval (Cl), 1.390-2.977, p = 0.016, and OR, 2.204; 95% Cl, 1.512-2.916, p = 0.020, respectively]. Conclusions: Reduction in hs-CRP levels in AM I patients plays an important role in the beneficial effects of statins on the regression and compositional change of coronary plaque.
