Background: Statins form an integral part of secondary prevention of myocardial ischaemia. There is widespread consensus regarding a preference for high-intensity therapy from the outset [1Stone N.J. et al.ACC/AHA Blood Cholesterol Guideline 2013 ACC/AHA Guideline on the Treatment of Blood Cholesterol to Reduce Atherosclerotic Cardiovascular Risk in Adult.Circulation. 2013; (2013; 01)Google Scholar, 2Schwartz G.G. et al.Effects of Atorvastatin on Early Recurrent Ischemic Events in Acute Coronary Syndromes: The MIRACL Study: A Randomized Controlled Trial.JAMA. 2001; 285 (4): 1711-1718Crossref PubMed Google Scholar]. Despite this, there remains a reluctance to prescribe higher, guideline doses of statins on discharge following acute coronary syndrome (ACS). Methods: We performed an audit of admission and discharge statin prescribing in all patients admitted to Wellington cardiology department with ACS over a 2-week period. This was followed by a departmental educational intervention and the effect was re-examined in a further 2-week re-audit. Statin intensity was specified based on published LDL-C lowering potency [[3]Weng T.-C. Yang Y.-H.K. Lin S.-J. Tai S.-H. A systematic review and meta-analysis on the therapeutic equivalence of statins.Journal of Clinical Pharmacy and Therapeutics. 2010; 35: 139-151Crossref PubMed Scopus (273) Google Scholar]. Low intensity: atorvastatin 10 mg, simvastatin 10-20 mg, pravastatin 20-40 mg. Moderate intensity: atorvastatin 20-40 mg, simvastatin 40-80 mg, pravastatin 80 mg, rosuvastatin 5-10 mg. High intensity: atorvastatin 80 mg, rosuvastatin 20-40 mg. The specific statin and dose selected were by physician preference. Results: 66 patients were identified pre-intervention and 70 post-intervention. The pre-interventional group was older (65 vs 60 years p = 0.02) and contained a lower proportion of men (71% vs 85% p = 0.03). There was no difference in statin intensity on admission between pre and post interventional groups, and only 8% overall were on high intensity therapy. There was a significant increase in the prescription of high intensity statin therapy post intervention. Conclusion: We found low rates of guideline, high intensity statin prescribing following acute coronary syndromes. After a simple educational intervention this was significantly improved.
