Article Synopsis
  • The study compares two strategies for managing high blood pressure in patients with ischaemic strokes who are eligible for intravenous thrombolysis: an active blood-pressure-lowering strategy and a conservative, non-lowering approach.
  • Conducted across 37 Dutch stroke centers, it involved eligible adults with elevated blood pressure and aimed to assess functional outcomes at 90 days, alongside secondary measures like complications and treatment timing.
  • The trial started in January 2015 but was prematurely halted due to low patient enrollment and lack of funding.

Objectives: Patients who have recently suffered a transient ischemic attack (TIA) or minor ischemic stroke are at increased risk of cognitive impairment. In the present study, we aimed to investigate the effect of a 1-year exercise intervention on cognitive functioning up to 2 years post intervention.

Material And Methods: We conducted a single-blind randomized controlled trial to investigate the effect of an exercise intervention on cognitive functioning, compared with usual care, for up to 2 years.

Background And Objectives: Endovascular thrombectomy (EVT) is standard treatment for anterior large vessel occlusion stroke (LVO-a stroke). Prehospital diagnosis of LVO-a stroke would reduce time to EVT by allowing direct transportation to an EVT-capable hospital. We aim to evaluate the diagnostic accuracy of dry electrode EEG for the detection of LVO-a stroke in the prehospital setting.

Introduction: Within the value-based healthcare framework, outcome data can be used to inform patients about (treatment) options, and empower them to make shared decisions with their health care professional. To facilitate shared decision-making (SDM) supported by outcome data, a multicomponent intervention has been designed, including patient decision aids on the organisation of post-treatment surveillance (breast cancer); discharge location (stroke) and treatment modality (advanced kidney disease), and training on SDM for health care professionals. The SHared decision-making supported by OUTcome information (SHOUT) study will examine the effectiveness of the intervention and its implementation in clinical practice.

Background: Obtaining informed consent for intravenous thrombolysis in acute ischemic stroke can be challenging, and little is known about if and how the informed consent procedure is performed by neurologists in clinical practice. This study examines the procedure of informed consent for intravenous thrombolysis in acute ischemic stroke in high-volume stroke centers in the Netherlands.

Methods: In four high volume stroke centers, neurology residents and attending neurologists received an online questionnaire concerning informed consent for thrombolysis with tissue-type plasminogen activator (tPA).

Background: In most hospitals, computed tomography angiography (CTA) is nowadays routinely performed in patients with acute ischemic stroke. However, it is unclear whether CTA is best performed before or after start of intravenous thrombolysis (IVT), since acquisition of CTA before IVT may prolong door-to-needle times, while acquisition after IVT may prolong door-to-groin times in patients undergoing endovascular treatment.

Methods: We performed a before-versus-after study (CTA following IVT, period I and CTA prior to IVT, period II), consisting of two periods of one year each.

Background And Aim: In acute ischemic stroke, under- or overestimation of body weight can lead to dosing errors of recombinant tissue plasminogen activator with consequent reduced efficacy or increased risk of hemorrhagic complications. Measurement of body weight is more accurate than estimation of body weight but potentially leads to longer door-to-needle times. Our aim was to assess if weight modality (estimation of body weight versus measurement of body weight) is associated with (i) symptomatic intracranial hemorrhage rate, (ii) clinical outcome, and (iii) door-to-needle times.

Background: Cardiorespiratory fitness (CRF) is reduced in patients with stroke. It is unclear whether it is also reduced in patients with a transient ischemic attack (TIA) or minor stroke. We investigated the CRF in patients with a recent TIA or minor stroke and explored which determinants are associated with a lower fitness.

Background And Purpose: Patients with a transient ischemic attack or ischemic stroke have an increased risk of subsequent cardiovascular events. The purpose of this systematic review and meta-analysis was to determine whether lifestyle interventions focusing on behaviorally modifiable risk factors with or without an exercise program are effective in terms of (1) preventing recurrent cardiovascular events, (2) reducing mortality, and (3) improving modifiable risk factors associated with cardiovascular disease in patients after a transient ischemic attack or ischemic stroke.

Methods: For this systematic review and meta-analysis, we systematically searched PubMed, Embase, PsycInfo, and the Cochrane Library from the start of the database to May 7, 2015.

Background: The clinical benefit of intravenous thrombolysis (IVT) in acute ischemic stroke is time dependent. Several studies report a short median door-to-needle time (DNT; 20 min), mainly in large tertiary referral hospitals equipped with a level 1 emergency department, a dedicated stroke team available 24/7, and on-site neuroimaging facilities. Meanwhile, in daily practice, the majority of stroke patients are admitted to secondary care hospitals, and in practice, even the generous benchmark of the American Heart Association (a DNT of 60 min in >80% of the cases) is met for a minority of patients treated with IVT.

Background: Few studies have focused on the quality of care with regard to long-term secondary prevention after transient ischemic attack (TIA) or ischemic stroke. The aim of this study was 2-fold: (1) to determine if ischemic stroke and TIA patients are motivated for a long-term secondary prevention program after hospital discharge and (2) to study the effect of this program on the attainment of guideline-recommended secondary prevention targets.

Methods: A single-center, cohort study of ischemic stroke and TIA patients.

Background: Stroke guidelines emphasize the importance of adequate vascular risk factor assessment and management in transient ischemic attack (TIA) and ischemic stroke patients, but it is not clear how these guidelines are applied in routine clinical practice. The limited data that are available indicate that TIA and ischemic stroke patients often do not receive the recommended interventions. The aim of this study was to investigate practice variations in long-term secondary stroke prevention in The Netherlands.

Background: Providing intravenous thrombolysis with short door-to-needle time is the result of a complex process that requires specific work standards. To expedite care for acute ischemic stroke patients, close collaboration between all participating health care professionals is required. The aim of this project was to reduce in-hospital treatment delay for acute ischemic stroke patients through the introduction of a standard operating procedure and by creating higher and sustained awareness of the importance of intravenous thrombolysis.

Cardiac rehabilitation programmes reduce mortality in patients following myocardial infarction. Patients with a history of transient ischaemic attack (TIA) or ischemic stroke have a high risk of recurrent stroke or other cardiovascular events, comparable with the risk that myocardial infarction patients show for recurrence. Evidence for the effectiveness of secondary prevention strategies following TIA and ischemic stroke is compelling.
