Background There is concern that blood pressure(BP)lowering in acute stroke may compromise cerebral perfusion and worsen outcome in the presence of carotid stenosis.We assessed the effect of glyceryl trinitrate(GTN)in patients with carotid stenosis using data from the Efficacy of Nitric Oxide in Stroke(ENOS)Trial.Methods ENOS randomised 4011 patients with acute stroke and raised systolic BP(140-220 mm Hg)to transdermal GTN or no GTN within 48 hours of onset.Those on prestroke antihypertensives were also randomised to stop or continue their medication for 7 days.The primary outcome was the modified Rankin Scale(mRS)at day 90.Ipsilateral carotid stenosis was split:<30%;30-<50%;50-<70%;≥70%.Data are ORs with 95%CIs adjusted for baseline prognostic factors.results 2023(60.5%)ischaemic stroke participants had carotid imaging.As compared with<30%,≥70%ipsilateral stenosis was associated with an unfavourable shift in mRS(worse outcome)at 90 days(OR 1.88,95%CI 1.44 to 2.44,p<0.001).Those with≥70%stenosis who received GTN versus no GTN had a favourable shift in mRS(OR 0.56,95%CI 0.34 to 0.93,p=0.024).In those with 50-<70%stenosis,continuing versus stopping prestroke antihypertensives was associated with worse disability,mood,quality of life and cognition at 90 days.Clinical outcomes did not differ across bilateral stenosis groups.Conclusions Following ischaemic stroke,severe ipsilateral carotid stenosis is associated with worse functional outcome at 90 days.GTN appears safe in ipsilateral or bilateral carotid stenosis,and might improve outcome in severe ipsilateral carotid stenosis. 展开更多

Introduction Nitrate-induced headache is common and may signify responsive cerebral vasculature.We assessed the relationship between nitrate headache and outcome in patients with acute stroke.Materials and methods Patients were those randomised to glyceryl trinitrate(GTN)versus no GTN in the efficacy of nitric oxide in stroke trial.Development of headache by end of treatment(day 7),and functional outcome(modified Rankin Scale,primary outcome)at day 90,were assessed.Analyses are adjusted for baseline prognostic factors and give OR and mean difference(MD)with 95%CI.Results In 4011 patients,headache was more common in GTN than control(360,18.0% vs 170,8.5%;p<0.001).Nitrate-related headache was associated with:younger age,female sex,higher diastolic blood pressure,non-total anterior circulation syndrome,milder stroke and absence of dysphasia(p<0.05).Nitrate headache was not associated with improved functional outcome(OR 0.90,95% CI 0.73 to 1.10,p=0.30)or death(day 90)(HR 0.64,95% CI 0.40 to 1.02,p=0.062),but reduced death or deterioration(day 7)(OR 0.45,95% CI 0.25 to 0.82),death in hospital(OR 0.44,95% CI 0.22 to 0.88)and improved activities of daily living(Barthel index,MD 3.7,95% CI 0.3 to 7.1)and cognition(telephone interview cognitive screen,MD 2.0,95% CI 0.7 to 3.3)(day 90).Non-nitrate headache was not associated with death,disability or cognition.Discussion and conclusion Development of a nitrate headache by day 7 after stroke may be associated with improved activities of daily living and cognitive impairment at day 90,which was not seen with non-nitrate headache. 展开更多
