Objective: To compare the effectiveness of statins of different treatment intensity used to treat elderly patients with acute coronary syndrome (ACS) in typical care settings.Design: Retrospective cohort study using linked hospital and pharmacy claims data.Setting: Statewide pharmacy benefits programmes in Pennsylvania and New Jersey.Participants: 18 311 Medicare patients discharged alive after ACS who received a prescription for a statin within 90 days of hospital discharge.Main outcome measures: Using multivariable and propensity-matched Cox proportional hazards regression models, patients who were prescribed high- intensity and moderate-intensity statins were compared based on the drug - dose combination that they initially received. Individual drug - dose combinations were also compared. Our primary outcome was the composite of all-cause death or recurrent ACS.Results: Patients who received moderate-intensity statins were as likely to experience a primary outcome as patients treated with high-intensity statins (adjusted HR 1.02, 95% CI 0.96 to 1.08). Propensity matching did not change the results. Individually, all moderate- intensity statins were as effective as high-intensity atorvastatin with the exception of lovastatin (adjusted HR 1.22, 95% CI 1.09 to 1.36). Similarly, all high-intensity statins seem as effective as high-intensity atorvastatin but the CIs surrounding these estimates were wide.Conclusions: This analysis of elderly patients with ACS treated in typical care settings does not demonstrate the superiority of high-intensity over moderate-intensity statin treatment or significant differences among individual statins.
