Abstract

BACKGROUND:High-potency statin therapy is recommended in the secondary prevention of car-diovascular disease but discontinuation, dose reduction, statin switching, and/or nonadherence occurin practice.OBJECTIVES:To determine the prevalence and predictors of deviation from high-potency statin useearly after a non-ST elevation acute coronary syndrome (NSTE-ACS) and its association with subse-quent major adverse cardiovascular events (MACE) and all-cause mortality (ACM).METHODS:A total of 1005 patients from a UK-based prospective NSTE-ACS cohort study dis-charged on high-potency statin therapy (atorvastatin 80 mg, rosuvastatin 20 mg, or 40 mg daily)were included. At 1 month, patients were divided into constant high-potency statin users, and subop-timal users incorporating statin discontinuation, dose reduction, switching statin to a lower equivalentpotency, and/or statin nonadherence. Follow-up was a median of 16 months.RESULTS:There were 156 suboptimal (w15.5%) and 849 constant statin users. Factors associatedin multivariable analysis with suboptimal statin occurrence included female sex (odds ratio 1.75, 95%confidence interval [CI] 1.14–2.68) and muscular symptoms (odds ratio 4.28, 95% CI 1.30–14.08).Suboptimal statin use was associated with increased adjusted risks of time to MACE (hazard ratio2.10, 95% CI 1.25–3.53,P5.005) and ACM (hazard ratio 2.46, 95% CI 1.38–4.39,P5.003). Sub-group analysis confirmed that the increased MACE/ACM risks were principally attributable to statindiscontinuation or nonadherence.CONCLUSIONS:Conversion to suboptimal statin use is common early after NSTE-ACS and ispartly related to muscular symptoms. Statin discontinuation or non-adherence carries an adverse prog-nosis. Interventions that preserve and enhance statin utilization could improve post NSTE-ACSoutcomes.
