OBJECTIVES: To investigate the effects of loading dose of atorvastatin on periprocedural myocardial injury and inflammatory reaction in patients with non-ST segment elevation (NSTE) acute coronary syndromes (unstable angina or NSTE acute myocardial infarction).
METHODS: A total of 81 patients with NSTE-acute coronary syndromes were randomly divided into the pretreatment with atorvastatin group [80 mg 12 h before percutaneous coronary intervention (PCI), with a further 40 mg preprocedure dose] (n=41) or the placebo group (n=40). The main end point was a 30-day incidence of major adverse cardiac events (cardiac death, nonfatal acute myocardial infarction, or revascularization with either PCI or coronary artery bypass grafting). Creatine kinase-MB, cardiac troponin I, and high-sensitivity C-reactive protein levels were measured at the baseline and at 8 and 24 h after the procedure.
RESULTS: Major adverse cardiac events occurred in 2.4% of patients in the atorvastatin group and 22.5% of those in the placebo group (P=0.0161). This difference was mostly because of reduction in the incidence of myocardial infarction (2.4 vs. 20.0%; P=0.0307). Markers of the two groups were elevated after PCI; however, the higher values of creatine kinase-MB, cardiac troponin I, and high-sensitivity C-reactive protein in the atorvastatin treatment group were significantly lower than those in the placebo group (P<0.01).
CONCLUSION: Short-term pretreatment with a high dose of atorvastatin significantly reduces procedural myocardial injury in early PCI.
