REstart or STop Antithrombotics Randomised Trial (RESTART) (2021)
RESTART tested whether antiplatelet therapy can be safely re-started in patients who have survived an intracerebral haemorrhage.
Antiplatelet therapy reduces the risk of major vascular events for people with occlusive vascular disease, although it might increase the risk of intracranial haemorrhage. Patients surviving the commonest subtype of intracranial haemorrhage, intracerebral haemorrhage, are at risk of both haemorrhagic and occlusive vascular events, but whether antiplatelet therapy can be used safely is unclear.
RESTART aimed to estimate the relative and absolute effects of antiplatelet therapy on recurrent intracerebral haemorrhage and whether this risk might exceed any reduction of occlusive vascular events.
RESTART recruited 537 participants between 22 May 2013 and 31 May 2018 from 122 hospitals across the UK.
The main results, based on follow-up of these participants until 30 November 2018, were published in 2019. The final results after two years of extended follow-up were published in 2021.
