Abstract
BACKGROUND: Although high-dose statin therapy has been reported to improve outcomes in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI), patterns of statin usage for such patients have not been reported in real-world clinical practice.



HYPOTHESIS: Some clinical factors would affect the pattern of statin usage in patients with ACS.



METHODS: In the multicenter prospective registry, 3362 patients with ACS who underwent PCI were analyzed. High-dose statin treatment was defined as atorvastatin ≥40 mg or rosuvastatin ≥20 mg per day. The patterns of statin usage were investigated for 30 days after the index PCI.



RESULTS: High-dose statins were administered prior to PCI to 13.7% and 19.6% of patients with unstable angina/non-ST-elevated myocardial infarction (UA/NSTEMI) and ST-elevated myocardial infarction (STEMI), respectively (P < 0.001). After PCI, 476 (14.2%) patients were maintained on high-dose statins, and 550 (16.4%) patients received no statins. Independent factors associated with high-dose statin usage after PCI were STEMI (odds ratio [OR]: 1.704, 95% confidence interval [CI]: 1.321-2.197, P < 0.001), high total cholesterol level (OR: 1.445, 95% CI: 1.136-1.837, P = 0.003), and current smoker (OR: 1.556, 95% CI: 1.206-2.008, P < 0.011). The absence of hypercholesterolemia was an independent factor determining the nonuse of statins (OR: 0.229, 95% CI: 0.148-0.353, P < 0.001).



CONCLUSIONS: In real-world clinical practice, high-dose statin treatment is being underused despite extensive evidence for patients with ACS undergoing PCI, particularly in UA/NSTEMI. Efforts are needed to ensure that clinical practice complies with evidence-based guidelines.
