12-month follow-up results of high dose rosuvastatin loading before percutaneous coronary intervention in patients with acute coronary syndrome

Background: Statin pretreatment before percutaneous coronary intervention (PCI) is associated with a reduced incidence of short-term adverse events and periprocedural myocardial infarction (MI). However, the long-term effects of statin pretreatment have not been evaluated.

Methods: Consecutive 445 patients with acute coronary syndrome (ACS) who underwent PCI were randomly assigned to receive no statin treatment before PCI (control group, n=220) or to receive 40 mg rosuvastatin loading before PCI (rosuvastatin group, n=225). The incidence of major adverse cardiac events (MACE), including cardiac death, non-fatal MI, non-fatal stroke, and any ischemia-driven revascularization, was assessed after 12 months.

Results: During 11±3 months of follow-up, MACE occurred in 20.5% of patients in the control group and 9.8% of patients in the rosuvastatin group (p=0.002). The Kaplan-Meier curves showed that the incidence of death and non-fatal MI was significantly greater in the control group than in the rosuvastatin group (hazard ratio, 3.71; p=0.021). High-sensitivity C-reactive protein levels were less elevated in the rosuvastatin group than in the control group at 24 h after PCI. Multivariate analysis revealed that rosuvastatin loading was an independent predictor of a reduction in the risk of MACE at 12 months (odds ratio, 0.5; p=0.006).

Conclusions: High dose rosuvastatin loading before PCI significantly improved 12-month clinical outcomes in patients with ACS who underwent an early invasive strategy.
