Intravenous thrombolysis in nonagenarians with ischemic stroke.

چکیده
BACKGROUND AND PURPOSE Demographic changes will result in a rapid increase of patients age ≥90 years (nonagenarians), but little is known about outcomes in these patients after intravenous thrombolysis (IVT) for acute ischemic stroke. We aimed to assess safety and functional outcome in nonagenarians treated with IVT and to compare the outcomes with those of patients age 80 to 89 years (octogenarians). METHODS We analyzed prospectively collected data of 284 consecutive stroke patients age ≥80 years treated with IVT in 7 Swiss stroke units. Presenting characteristics, favorable outcome (modified Rankin scale [mRS] 0 or 1), mortality at 3 months, and symptomatic intracranial hemorrhage (SICH) using the National Institute of Neurological Disorders and Stroke (NINDS) and Safe Implementation of Thrombolysis in Stroke-Monitoring Study (SITS-MOST) criteria were compared between nonagenarians and octogenarians. RESULTS As compared with octogenarians (n=238; mean age, 83 years), nonagenarians (n=46; mean age, 92 years) were more often women (70% versus 54%; P=0.046) and had lower systolic blood pressure (161 mm Hg versus 172 mm Hg; P=0.035). Patients age ≥90 years less often had a favorable outcome and had a higher incidence of mortality than did patients age 80 to 89 years (14.3% versus 30.2%; P=0.034; and 45.2% versus 22.1%; P=0.002; respectively), while more nonagenarians than octogenarians experienced a SICH (SICH(NINDS), 13.3% versus 5.9%; P=0.106; SICH(SITS-MOST), 13.3% versus 4.7%; P=0.037). Multivariate adjustment identified age ≥90 years as an independent predictor of mortality (P=0.017). CONCLUSIONS Our study suggests less favorable outcomes in nonagenarians as compared with octogenarians after IVT for ischemic stroke, and it demands a careful selection for treatment, unless randomized controlled trials yield more evidence for IVT in very old stroke patients.

Intravenous Thrombolysis for Acute Ischemic Stroke due to Cardiac Myxoma; A Case Report
Myxoma may cause systemic embolization and frequently presents as ischemic stroke. There has been debates whether it is safe to use recombinant tissue plasminogen activator (rt-PA) in patients with cardiac myxoma who are presented with ischemic stroke at emergency department. we describe a young case of atrial myxoma with initial presentation of acute cerebral infarction symptoms who was treate...
متن کاملOutcomes of thrombolysis for acute ischemic stroke in octogenarians versus nonagenarians.
BACKGROUND AND PURPOSE Little is reported on the outcomes of nonagenarians who are treated with intravenous tissue plasminogen activator for acute ischemic stroke. It is uncertain whether nonagenarians have higher mortality and worse functional outcomes than octogenarians. METHODS All patients who were >or=80 years of age were extracted from the Canadian Activase for Stroke Effectiveness Stud...
