Importance: : The spatial and temporal distribution of intracerebral hemorrhage (ICH) recurrence are largely unknown.

Objective: To assess timing and location of recurrent ICH events in relation to the index ICH event (adjacent ICH [adjICH] vs remote ICH [remICH]).

Design, Setting, And Participants: This cohort study was a pooled analysis of individual cohort studies from 2002 to 2021 among hospital-based European cohorts.

Article Synopsis
  • The study looked at how patients with bleeding in the brain (called intracerebral hemorrhage) did after taking certain blood-thinning medicines or none at all.
  • It combined data from two countries (Switzerland and Norway) and checked the effects over 3 months on how well patients recovered and if they survived.
  • Results showed that patients who took blood thinners had a harder time recovering and were more likely to die compared to those who didn’t take any blood thinners.

Background: The safety and efficacy of oral anticoagulation for prevention of major adverse cardiovascular events in people with atrial fibrillation and spontaneous intracranial haemorrhage are uncertain. We planned to estimate the effects of starting versus avoiding oral anticoagulation in people with spontaneous intracranial haemorrhage and atrial fibrillation.

Methods: In this prospective meta-analysis, we searched bibliographic databases and trial registries using the strategies of a Cochrane systematic review (CD012144) on June 23, 2023.

Background In acute intracerebral hemorrhage, both elevated blood pressure (BP) and antithrombotic treatment are associated with poor outcome. Our aim was to explore interactions between antithrombotic treatment and prehospital BP. Methods and Results This observational, retrospective study included adult patients with spontaneous intracerebral hemorrhage diagnosed by computed tomography within 24 hours, admitted to a primary stroke center during 2012 to 2019.

Background And Aims: It is unclear whether patients with previous intracerebral hemorrhage (ICH) should receive antithrombotic treatment to prevent ischemic events. We assessed stroke physicians' opinions about this, and their views on randomizing patients in trials assessing this question.

Methods: We conducted three web-based surveys among stroke physicians in Scandinavia and the United Kingdom.

Background: High blood pressure (BP) is associated with poor outcome in acute spontaneous intracerebral hemorrhage. Little is known about the predictive value of prehospital BP in intracerebral hemorrhage. We aimed to investigate the relationship between prehospital BP and clinical and radiological outcomes.

Background And Aims: Many patients with prior intracerebral haemorrhage have indications for antithrombotic treatment with antiplatelet or anticoagulant drugs for prevention of ischaemic events, but it is uncertain whether such treatment is beneficial after intracerebral haemorrhage. STudy of Antithrombotic Treatment after IntraCerebral Haemorrhage will assess (i) the effects of long-term antithrombotic treatment on the risk of recurrent intracerebral haemorrhage and occlusive vascular events after intracerebral haemorrhage and (ii) whether imaging findings, like cerebral microbleeds, modify these effects.

Methods: STudy of Antithrombotic Treatment after IntraCerebral Haemorrhage is a multicentre, randomised controlled, open trial of starting versus avoiding antithrombotic treatment after non-traumatic intracerebral haemorrhage, in patients with an indication for antithrombotic treatment.

Background: To ensure the rapid and correct triage of patients in potential need of specialized treatment, Norwegian hospitals are expected to establish trauma teams with predefined criteria for their activation. The objective of this study was to map and describe the criteria currently in use.

Methods: We undertook a cross-sectional survey in the summer of 2008, using structured telephone interviews to all Norwegian hospitals that might admit severely injured patients.
