BACKGROUND: Statins have been proven to reduce cardiac events and mortality. However, there are few studies dealing with the long-term efficacy of statin therapy following percutaneous coronary intervention (PCI). METHODS: We collected data from 575 consecutive patients who underwent PCI between 1987 and 1992. The baseline data, mortality and incidence of cardiovascular events of patients given statins and those not given statins at the time of PCI were compared. RESULTS: There were 243 patients in the statin group and 332 patients in the non-statin group. During follow-up (11.0+/-3.0 years), 68 patients died. At about 10 years, statin use was significantly associated with lower all-cause mortality (8.2% versus 14.5%, P=0.023) and cardiac death (2.5% versus 6.9%, P=0.017). After adjusting for variables, statin use was found to be an independent predictor of death from all causes (hazard ratio [HR] 0.54, 95% confidence interval [CI] 0.29-0.99, P=0.048) and cardiac death (HR 0.24, 95% CI 0.07-0.80, P=0.02). CONCLUSION: Statin use at the time of PCI was associated with a significantly reduced risk of death from all causes and cardiac death. Furthermore, this study provides evidence of a clinical benefit at about 10 years of statin use in patients who underwent PCI.
