Abstract

Background: Data on atorvastatin pretreatment in Asian patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI) are limited. However, there have been studies in other populations in Asia which demonstrated that statins can reduce the risk of periprocedural myocardial infarction (MI). Methods and results: Statin-naïve patients with non-ST-segment-elevation (NSTE)-ACS scheduled for PCI were randomized to usual care or atorvastatin preloading groups. All patients received usual care including atorvastatin 40. mg/day. The atorvastatin group received atorvastatin 80. mg 12. h and 40. mg 2. h pre-PCI. Of 499 patients randomized, 247 were assigned to atorvastatin preloading. Following coronary angiography, 335 patients (163 atorvastatin) received PCI. During the 30 days post-PCI, major adverse cardiac events (death, MI, and target vessel revascularization) occurred in 24 (15%) atorvastatin and 27 (16%) usual care patients (p= NS). Post hoc analyses showed that at 8. h post-PCI, 3.82% of the atorvastatin group and 7.22% of the usual care group had a post-procedural creatine kinase-myocardial band (CK-MB) above 3 times the upper limit of normal (p= 0.27) and at 24. h post-PCI, the rate was 7.64% versus 9.47% (p= 1.0). Safety profile suggests that high-dose atorvastatin (40. mg) for up to 1 month, in conjunction with usual care, is relatively safe and well tolerated. Conclusions: This study of statin-naïve Korean and Chinese patients with NSTE-ACS who received additional atorvastatin loading doses of 80. mg at 12. h, and 40. mg at 2. h, pre-PCI did not find a beneficial effect compared with usual post-PCI atorvastatin 40. mg/day treatment. Atorvastatin was found to be well tolerated in Asian patients with NSTE-ACS undergoing PCI. Results of the current study merit further investigation of the early use of statins in patients with NSTE-ACS to delineate patient subgroups who may benefit from this therapy.
