BACKGROUND Intravenous thrombolysis for acute stroke is more efficient the earlier the treatment is initiated. In-hospital delays account for a significant proportion of avoidable time loss before treatment is initiated. Paradoxically, studies have reported longer door-to-needle times the earlier the patients arrive ('three-hour effect'). Hypothesis We(More)
BACKGROUND Fever after acute cerebral injury is associated with unfavorable functional outcome and increased mortality, but there is controversy about the optimal antipyretic treatment. This study investigated an institutional standard operating procedure (SOP) for fever treatment in stroke patients including a sequence of pharmacologic and physical(More)
BACKGROUND Many patients with stroke are precluded from thrombolysis treatment because the time from onset of their symptoms is unknown. We aimed to test whether a mismatch in visibility of an acute ischaemic lesion between diffusion-weighted MRI (DWI) and fluid-attenuated inversion recovery (FLAIR) MRI (DWI-FLAIR mismatch) can be used to detect patients(More)
BACKGROUND AND PURPOSE Patients with acute cerebrovascular events are susceptible to serious cardiac arrhythmias, but data on the time course and the determinants of their onset are scarce. METHODS The prospective Stroke-Arrhythmia-Monitoring-Database (SAMBA) assessed cardiac arrhythmias with need for urgent evaluation and treatment in 501 acute(More)
BACKGROUND Up to 25% of all acute ischaemic strokes occur during sleep. Because of the unclear time window, patients with stroke on awakening are usually not considered for acute therapy and excluded from most acute treatment trials. AIM To evaluate the feasibility of magnetic resonance imaging-based intravenous thrombolysis in patients with stroke on(More)
BACKGROUND AND PURPOSE Recombinant tissue plasminogen activator is used for the treatment of acute myocardial infarction, pulmonary embolism, and acute ischemic stroke. With many years since approval of the drug and an aging population, chances increase that patients are treated twice for chronologically separated events. METHODS We identified patients(More)
BACKGROUND Recombinant tissue plasminogen activator (rt-PA) is the only approved specific therapy for acute ischemic stroke. This study analyzes demographic and clinical characteristics of patients with early complete neurological recovery after thrombolysis. METHODS Data of 320 consecutive patients treated with rt-PA within 3 h of stroke onset at our(More)
BACKGROUND AND PURPOSE Inverse relationship between onset-to-door time (ODT) and door-to-needle time (DNT) in stroke thrombolysis was reported from various registries. We analyzed this relationship and other determinants of DNT in dedicated stroke centers. METHODS Prospectively collected data of consecutive ischemic stroke patients from 10 centers who(More)
BACKGROUND Approximately 5-10% of all acute ischemic strokes (AIS) occur in the territory of the posterior cerebral artery (PCA). Little is known about intravenous thrombolysis (IVT) in this infarct subgroup in terms of outcome and intracerebral hemorrhage rates. The aim of our study was to evaluate differences between supratentorial PCA infarcts and(More)
BACKGROUND Platelet counts (PCs) <100,000/µl are considered as a contraindication for intravenous thrombolysis (IVT). While US guidelines recommend IVT initiation before the availability of clotting tests, the guidelines of the European Stroke Organization give no such practical advice. We aimed to assess the incidence of thrombocytopenia in IVT patients,(More)
