The Bolus Alteplase Pulmonary Embolism (BAPE) Group and a consortium of French investigators utilized essentially the same investigational protocol to test reduced dose bolus alteplase vs full dose 100 mg/2 h alteplase in the treatment of pulmonary embolism (PE). The principal hypothesis was that reduced dose bolus alteplase (n = 96) would result in fewer bleeding complications than full dose 1...
BACKGROUND AND PURPOSE We compared the fibrinolytic activity of tenecteplase and alteplase in patients with acute ischemic stroke, and explored the association between hypofibrinogenaemia and intracerebral hemorrhage. METHODS Venous blood samples from a subgroup of participants in the Alteplase-Tenecteplase Trial Evaluation for Stroke Thrombolysis (ATTEST) study were obtained at pretreatment,...
This situation reflects the history of IV thrombolysis for acute stroke treatment. In 1995, the NINDS trial first showed the efficacy of alteplase (0.9 mg/kg) for acute ischemic stroke. The dosage of 0.9 mg/kg was decided according to the two pilot studies [8, 9] , despite any attempts to investigate the apparent dose effect of alteplase in these studies. Similarly, in Japan, although observati...
BACKGROUND Thrombolysis with intravenous alteplase is the only approved treatment for acute ischaemic stroke. After alteplase-induced recanalisation, reocclusion occurs in 14-34% of patients, probably because of platelet activation. Early administration of antiplatelet therapy after alteplase could reduce the risk of reocclusion and improve outcome. We compared the effects of early addition of ...
BACKGROUND The TIMI 14 trial tested the hypothesis that abciximab, the Fab fragment of a monoclonal antibody directed to the platelet glycoprotein (GP) IIb/IIIa receptor, is a potent and safe addition to reduced-dose thrombolytic regimens for ST-segment elevation MI. METHODS AND RESULTS Patients (n=888) with ST-elevation MI presenting <12 hours from onset of symptoms were treated with aspirin...
Background: Rapid alteplase delivery for ischemic stroke patients has been shown to increase the likelihood of disability-free life. Identification of barriers to rapid alteplase delivery and streamlining processes around imaging assessments are important. Our aim was to examine the relationships between hospital arrival time and postimaging processes in stroke thrombolysis. Methods: De-identif...
Alteplase has traditionally been the only pharmacologic agent available for treating acute ischemic stroke worldwide, and is considered an effective and safe therapeutic drug for acute cerebral ischemia. However, the drug is usually indicated for use in patients aged <81 years due to insufficient literature regarding the drug's safety in older individuals. Nevertheless, the elderly can benefit ...
BACKGROUND AND PURPOSE No exclusive systematic data exist on the safety and outcomes of thrombolytic treatment in young patients with ischemic stroke. METHODS We evaluated all 48 patients aged 16 to 49 years with hemispheric ischemic stroke treated with intravenous alteplase in Helsinki University Central Hospital from 1994 to 2007. For comparison of outcome, we selected, blinded to outcome d...
BACKGROUND Lanoteplase (nPA) is a rationally designed variant of tissue plasminogen activator with greater fibrinolytic potency and slower plasma clearance than alteplase. METHODS AND RESULTS InTIME (Intravenous nPA for Treatment of Infarcting Myocardium Early), a multicenter, double-blind, randomized, double-placebo angiographic trial, evaluated the dose-response relationship and safety of s...
BACKGROUND AND PURPOSE Many patients receiving thrombolysis for acute ischemic stroke are on prior antiplatelet therapy (APT), which may increase symptomatic intracerebral hemorrhage risk. In a prespecified subgroup analysis, we report comparative effects of different doses of intravenous alteplase according to prior APT use among participants of the international multicenter ENCHANTED study (E...
