ABSTRACT
BACKGROUND:
There is no information on differences in the effects of moderate- and low-intensity statins on coronary plaque in patients with acute coronary syndrome (ACS). The aim of this study was to compare the effects of 4 different statins in patients with ACS, using intravascular ultrasound (IVUS). METHODSâANDâRESULTS:
A total of 118 patients with ACS who underwent IVUS before percutaneous coronary intervention and who were found to have mild to moderate non-culprit coronary plaques were randomly assigned to receive either 20 mg/day atorvastatin or 4 mg/day pitavastatin (moderate-intensity statin therapy), or 10 mg/day pravastatin or 30 mg/day fluvastatin (low-intensity statin therapy). IVUS at baseline and at end of 10-month treatment was available in 102 patients. Mean percentage change in plaque volume (PV) was -11.1±12.8%, -8.1±16.9%, 0.4±16.0%, and 3.1±20.0% in the atorvastatin, pitavastatin, pravastatin, and fluvastatin groups, respectively (P=0.007, ANOVA). Moderate-intensity statin therapy induced regression of PV, whereas low-intensity statin therapy produced insignificant progression (-9.6% vs. 1.8%, P<0.001). On multivariate linear regression analysis, moderate-intensity statin therapy (P=0.02) and uric acid at baseline (P=0.02) were significant determinants of large percent PV reduction. LDL-C at follow-up did not correlate with percent PV change.CONCLUSIONS:
Moderate-intensity statin therapy induced regression of coronary PV, whereas low-intensity statin therapy resulted in slight progression of coronary PV in patients with ACS. (Circ J 2016; 80 1634-1643).
