Statins are recommended for prevention of progression of cardiovascular disease after percutaneous coronary intervention (PCI). Although high-dose highly efficient statins are recommended, especially in high-risk patients, clinical data are scarce and further investigation in "real-world" settings is needed. One thousand five hundred twenty-eight consecutive patients, who underwent PCI for acute coronary syndrome, were included in a prospective registry from January 2003 to January 2011. In post hoc analysis, cardiovascular risk factors, co-morbidities, and circulating lipid parameters at the time of intervention were evaluated. As a primary end point, all-cause mortality after a follow-up period of 3 months was investigated. Results were compared between patients receiving high-dose highly effective statins (atorvastatin 80 mg or rosuvastatin 20 mg) versus patients receiving low-dose statins or who were without lipid-lowering therapy at the time of discharge. Nine hundred twenty-six patients (60.6%) received high-dose atorvastatin or rosuvastatin and 602 patients (39.4%) received low-dose statin therapy or were not on statins at discharge. Eight patients (0.9%) receiving high-dose statin therapy and 21 patients (3.5%) taking low-dose statins or no statins at discharge died during the 3-month follow-up (hazard ratio 0.244, 95% confidence interval 0.108 to 0.551, p=0.001). After propensity score adjustment the results remained significant (adjusted hazard ratio for high-dose statins 0.405, 95% confidence interval 0.176 to 0.931, p=0.033). In conclusion, in this single-center series of 1,528 real-world patients undergoing PCI for acute coronary syndrome, a significant reduction in short-term all-cause mortality could be demonstrated in patients receiving high-dose highly efficient statins compared with patients receiving low-dose statins or no lipid-lowering therapy.
