Comparison of acute nonthrombolytic and thrombolytic treatments in ischemic stroke patients 80 years or older

ObjectivesThe aim of this study was to compare the clinical outcomes of acute ischemic stroke patients 80 years or older treated with intravenous recombinant tissue plasminogen activator (IV rt-PA), or endovascular intervention with or without IV rt-PA, or nonthrombolytic medical treatment.MethodsThis study was a retrospective, nonrandomized, observational study of patients, admitted within 9 hours of symptom onset, at 3 academic, university-affiliated hospitals. The main outcome measures were neurologic improvement, defined by improvement in National Institutes of Health Stroke Scale score at 7 days or discharge of 4 or more, or achieving a score of 0; symptomatic and asymptomatic intracerebral hemorrhage; favorable outcome (discharge modified Rankin score 0-2); and in-hospital mortality.ResultsA total of 44 patients received IV rt-PA, 46 received endovascular intervention with or without IV rt-PA, and 66 received nonthrombolytic medical treatment. IV rt-PA–treated patients had a significantly clinically higher chance of favorable outcome (odds ratio [OR], 5.6; 95% confidence interval [CI], 1.8-17.5), when compared with nonthrombolytic medical treatment. A significantly higher rate of neurologic improvement was observed among the IV rt-PA (7.2; 95% CI, 2.7-19.5) and endovascularly treated patients (5.8; 95% CI, 2-16.8) when compared with nonthrombolytic medical treatment.ConclusionsA prominently higher rate of neurologic improvement and favorable clinical outcome was observed among acute ischemic stroke patients 80 years or older treated with IV rt-PA or endovascular intervention when compared with nonthrombolytic medical treatment, supporting the use of acute thrombolytic therapies in this patient population when contraindications are not present.
