Outcome of intravenous recombinant tissue plasminogen activator for acute ischemic stroke in patients aged over 80 years

Abstract : AIM:Practitioners are faced with a substantial challenge when considering recombinant tissue plasminogen activator (rt-PA) therapy for older patients with ischemic stroke. Patients aged over 80 years suffer from the most severe cerebral infarcts. The benefit of rt-PA treatment compared with single standard care only in stroke units remains to be clearly assessed.METHODS:We collected data from 321 patients aged over 80 years admitted for acute cerebral infarction to the stroke unit of Nancy University Hospital in France between 1 January 2009 and 31 December 2012. Patients were stratified into two groups: treated or not with rt-PA. Baseline characteristics and outcome were collected and compared between both groups. Good outcome at 3 months was defined as modified Rankin Scale score ≤2.RESULTS:The 55 patients treated with rt-PA had a higher National Institute of Health Stroke Scale score on admission than those without (15 vs 5; P < 0.001). They were more likely to have intracranial haemorrhage (20 vs 5%; P < 0.001) without an increased mortality rate (28 vs 27%; P = 0.95). Multivariate analysis showed a more favorable outcome (odds ratio 7, 95% confidence interval 3-16.5; P < 0.001). Slightly higher percentages of patients with modified Rankin Scale ≤2 were found after intention-to-treat analysis (49 vs 45%) and after exclusion of patients with baseline modified Rankin Scale >2 (57 vs 54 %), but without reaching significance (P > 0.05).CONCLUSIONS:Rt-PA therapy would appear to improve prognosis in the elderly with ischemic stroke. This suggests that age alone should no longer be a barrier to rt-PA therapy.
