Trends in the use of statins after ischaemic stroke: Have clinical practices changed?

ABSTRACT

INTRODUCTION: The role of statins after ischaemic stroke changed with the publication of the SPARCL study in 2006. We analyse how this has influenced the prescription of statins in this patient population. METHODS: We conducted a retrospective study of patients discharged with ischaemic stroke at the Virgen Macarena, Virgen del Rocío, and Valme hospitals in Seville (Spain) over two periods 1999-2001 and 2014-2016. RESULTS: The study included 1575 patients 661 (42%) were women and mean age (standard deviation) was 69 (10) years. Patients from the later period are older (68 [10] vs 71 [11]; P = .0001); include a higher proportion of women; and present higher rates of dyslipidaemia, hypertension, and diabetes. At discharge, statins were used in 18.7% of patients (vs 86.9% in the first period; P = .0001), with high-intensity statins prescribed in 11.1% of cases (vs 54.4%; P = .0001). In both periods, atorvastatin was the most commonly prescribed statin (80 mg 6% vs 42.7%; 40 mg 5.1% vs 11.1%). In the first period, the use of statins and high-intensity statins was correlated with hypercholesterolaemia, and inversely correlated with age. In the second period, statin use was correlated with hypertension and hypercholesterolaemia, and high-intensity statin use was correlated with ischaemic heart disease and inversely correlated with age. CONCLUSION: There has been a clear change in the prescription of statins to patients with ischaemic stroke at discharge. However, many patients remain undertreated and the use of these drugs needs to be optimised.
