AbstractBoth randomized and observational studies have suggested that pretreatment with statins may reduce the incidence of periprocedural myocardial infarction (PMI) in patients with stable angina during elective percutaneous coronary intervention (PCI). The purpose of this randomized study (Clinical Trial Registration No. NCT00469326) was to investigate the effect of 2-day atorvastatin therapy on the incidence of PMI in patients with stable angina pectoris undergoing elective PCI. A total of 200 patients with stable angina pectoris who were not taking statins and who had been referred for PCI were enrolled and randomized (ratio 1:1) to a 2-day pretreatment regimen with atorvastatin 80 mg/day and subsequent PCI or immediate PCI. The serum concentration of creatine kinase-MB mass and troponin I were measured before and 16 to 24 hours after PCI. The incidence of PMI was assessed using established criteria. Of the patients, 10% in the atorvastatin group and 12% in the control group had a postprocedural creatine kinase-MB mass elevation > or =3 times the upper limit of normal (p = 0.65). The incidence of PMI as determined by the postinterventional release of troponin I > or =3 times the upper limit of normal was 17% in the atorvastatin group and 16% in the control group (p = 0.85). The median creatine kinase-MB mass peak after PCI was 1.46 ng/ml (interquartile range 0.83 to 2.52) in the atorvastatin group and 1.40 ng/ml (interquartile range 0.90 to 2.54) in the control group (p = 0.70). The median peak troponin I level after PCI was 0.100 ng/ml (0.096 to 0.385) in the atorvastatin group and 0.100 ng/ml (0.60 to 0.262) in the control group (p = 0.54). On multivariate analysis, the only independent predictor of PMI was patient age (odds ratio 1.09, 95% confidence interval 1.025 to 1.159, p = 0.006). In conclusion, in the present study 2-day pre-PCI therapy with atorvastatin did not reduce the occurrence of PMI in patients with stable angina pectoris undergoing elective PCI.
