There is evidence that statin therapy in patients with a history of ischaemic stroke or TIA significantly reduces subsequent major coronary events but only marginally reduces the risk of stroke recurrence .
There is no clear evidence of beneficial effect from statins in those with previous haemorrhagic stroke and it is unclear whether statins should be started immediately post stroke or later .
BACKGROUND Studies have shown that interventions which reduce total and low-density lipoprotein cholesterol levels also reduce coronary heart disease ( CHD ) and stroke events in those with a history of CHD .
However , it is uncertain whether treatment to alter cholesterol levels can prevent recurrence of either stroke or subsequent cardiovascular events and whether differences in outcomes exist between classes of lipid-lowering therapy .

Fast assessment of stroke and transient ischaemic attack to prevent early recurrence (FASTER): a randomised controlled pilot trial
BACKGROUND Patients with transient ischaemic attack ( TIA ) or minor stroke are at high immediate risk of stroke . The optimum early treatment options for these patients are not known . METHODS Within 24 h of symptom onset , we r and omly assigned , in a factorial design , 392 patients with TIA or minor stroke to clopidogrel  ( 300 mg loading dose then 75 mg daily ; 198 patients ) or placebo ( 194 patients ) , and simvastatin ( 40 mg daily ; 199 patients ) or placebo ( 193 patients ) . All patients were also given aspirin and were followed for 90 days . Descriptive analyses were done by intention to treat . The primary outcome was total stroke ( ischaemic and haemorrhagic ) within 90 days . Safety outcomes included haemorrhage related to clopidogrel and myositis related to simvastatin . This study is registered as an International St and ard R and omised Controlled Trial ( number 35624812 ) and with Clinical Trials.gov ( NCT00109382 ) . FINDINGS The median time to stroke outcome was 1 day ( range 0 - 62 days ) . The trial was stopped early due to a failure to recruit patients at the prespecified minimum enrolment rate because of increased use of statins . 14 ( 7.1 % ) patients on clopidogrel had a stroke within 90 days compared with 21 ( 10.8 % ) patients on placebo ( risk ratio 0.7 [ 95 % CI 0.3 - 1.2 ] ; absolute risk reduction -3.8 % [ 95 % CI -9.4 to 1.9 ] ; p=0.19 ) . 21 ( 10.6 % ) patients on simvastatin had a stroke within 90 days compared with 14 ( 7.3 % ) patients on placebo ( risk ratio 1.3 [ 0.7 - 2.4 ] ; absolute risk increase 3.3 % [ -2.3 to 8.9 ] ; p=0.25 ) . The interaction between clopidogrel and simvastatin was not significant ( p=0.64 ) . Two patients on clopidogrel had intracranial haemorrhage compared with none on placebo ( absolute risk increase 1.0 % [ -0.4 to 2.4 ] ; p=0.5 ) . There was no difference between groups for the simvastatin safety outcomes . INTERPRETATION Immediately after TIA or minor stroke , patients are at high risk of stroke , which might be reduced by using clopidogrel in addition to aspirin . The haemorrhagic risks of the combination of aspirin and clopidogrel do not seem to offset this potential benefit . We were unable to provide evidence of benefit of simvastatin in this setting . This aggressive prevention approach merits further study
