Multicenter StudyTissue plasminogen activator thrombolytic therapy for acute ischemic stroke in 4 hospital groups in Japan.
In October 2005 in Japan, the recombinant tissue plasminogen activator (tPA) alteplase was approved for patients with acute ischemic stroke within 3 hours of onset at a dose of 0.6 mg/kg. The present study was undertaken to assess the safety and efficacy of alteplase in Japan. Between October 2005 and December 2009, a total of 114 consecutive patients admitted to 4 hospitals received intravenous tPA within 3 hours of stroke onset. ⋯ Intracerebral hemorrhage (ICH) occurred in 26 patients (22.8%); compared with patients without ICH, these patients had a significantly higher prevalence of cardiogenic embolism (88.5% vs 58.0%); greater warfarin use (26.8% vs 6.8%); higher mean National Institutes of Health Stroke Scale (NIHSS) scores on admission (16 vs 10), at 3 days after admission (14 vs 5), and at 7 days after admission (13.5 vs 3); and a lower Diffusion-Weighted Imaging-Alberta Stroke Program Early CT Score (7.8 vs 9.1). Patients who received edaravone had a higher prevalence of cardiogenic embolism (70.9% vs 36.4%), a higher recanalization rate (77.7% vs 36.4%), and lower NIHSS scores on admission and at 3 and 7 days after admission compared with those who did not receive edaravone. Our data suggest that administration of intravenous alteplase 0.6 mg/kg within 3 hours of stroke onset is safe and effective, that the NIHSS and Diffusion-Weighted Imaging-Alberta Stroke Program Early CT Score are useful predictors of ICH after tPA administration, and that warfarin-treated patients are more likely to develop symptomatic ICH despite an International Normalized Ratio <1.7.

Multicenter Study Comparative StudyThrombolysis for acute ischemic stroke in Joint Commission-certified and -noncertified hospitals in Michigan.
The Joint Commission (JC) for Accreditation of Healthcare Organizations has devised disease specific certification programs for hospitals, including stroke. JC certification as a primary stroke center (PSC) suggests that the hospital has critical measures in place to ensure improving stroke outcomes over the long term. In this study, we focused on the delivery of care for patients with acute ischemic and compared differences in JC-certified and -noncertified centers in Michigan. ⋯ Rates of thrombolysis administration for acute stroke patients across Michigan were low in both JC-certified and noncertified hospitals, although better processes were in place in JC-certified PSCs. While there was no overall difference in the administration of thrombolytic treatment, a greater number of the eligible patients received thrombolysis in the certified centers. There was a tendency to shorter lengths of stay at JC-certified PSCs, but there was no significant difference in discharge to home, inpatient rehabilitation, or inpatient mortality in this study.

Multicenter Study Comparative StudyComparison of single versus multiple spontaneous extra- and/or intracranial arterial dissection.
Anecdotal data suggest that approximately 20% of patients with a spontaneous extra- and/or intracranial arterial dissection have multiple arterial involvement. Limited data exist regarding the clinical and angiographic characteristics of patients with multiple arterial dissections. We compared the clinical and angiographic features of patients with spontaneous multiple extra- and/or intracranial arterial dissections with those who have a single arterial dissection. ⋯ The presence of multiple, simultaneous spontaneous extra- and/or intracranial arterial dissections must be considered when a single spontaneous arterial dissection is identified.

Multicenter StudyLow Alberta stroke program early computed tomography score within 3 hours of onset predicts subsequent symptomatic intracranial hemorrhage in patients treated with 0.6 mg/kg Alteplase.
The significance of early ischemic changes (EICs) on computed tomography (CT) in selecting candidates for thrombolysis remains controversial. The Alberta Stroke Program Early CT Score (ASPECTS) provides a semiquantitative scale that scores EICs within the middle cerebral artery territory using a 10-point grading system. We examined whether ASPECTS can predict the response to intravenous thrombolysis within 3 hours of stroke onset and incidence of secondary hemorrhage. ⋯ In J-ACT, patients with low ASPECTS values have an increased risk of thrombolysis-related sICH.

Multicenter StudyComplications in acute stroke in India (CAST-I): a multicenter study.
The prognosis and final outcome in patients who sustain stroke are significantly affected by medical complications occurring during the acute phase of stroke. Only limited information is available from India and other developing countries regarding acute complications of stroke. This study examined the frequency of acute stroke and the factors associated with complications of stroke in India. ⋯ Our study shows high rates of complication in acute stroke. Limb weakness, stroke severity, length of hospital stay, and anemia were the factors associated with complications. Other complications, such as urinary tract infection, chest infection, bedsores, other pain, and depression, can lead to poor outcome.
