BACKGROUND AND OBJECTIVE: This study was designed to investigate whether high-dose atorvastatin before percutaneous coronary intervention (PCI) can reduce inflammation, platelet activation, and major adverse cardiac events (MACE) in patients with stable angina who are undergoing long-term statin therapy. METHODS: In total, 215 patients with chronic stable angina were randomized to pretreatment with 80 mg of atorvastatin (12 h before PCI; n = 106) or with 20 mg of atorvastatin (12 h before PCI; n = 109). All patients underwent PCI. Serum levels of interleukin-6, high-sensitivity C-reactive protein, tumor necrosis factor-α, GMP-140, and p-selectin were measured 24 h before and after PCI. The 30-day incidence of MACE was determined. RESULTS: No differences in baseline characteristics were observed between the groups. The levels of inflammation and platelet activation were significantly lower after 24 h in the group that received intensive statin therapy (P < 0.05). The levels of inflammation and platelet activation increased sharply 24 h after PCI in the group that received the lower dose of atorvastatin (P > 0.05). In other words, pretreatment with a high dose of atorvastatin decreased the incidence of MACE sharply within 30 days (P < 0.05). CONCLUSIONS: Pretreatment with a high dose of atorvastatin significantly reduced inflammation, platelet activation, and the incidence of MACE in patients with stable angina.
