What is the prognostic significance of clinical and radiological haemorrhagic transformation subtypes on functional outcome and mortality in acute ischaemic stroke patients?
Different subtypes of haemorrhagic transformation in acute ischaemic stroke carry distinct prognostic implications, with parenchymal haematoma and symptomatic intracerebral haemorrhage driving mortality and worse functional outcomes.
Regardless of whether AIS patients undergo thrombolysis or thrombectomy, overall HT, sICH and PH (especially PH-2) are associated with a substantially increased risk of worse functional outcome, mortality, END or neurological complications. The presence of aICH is related to worse functional outcome but is independent of increased mortality. HI-2 impairs functional independence, and HI-1 does not cause neurological impairment.
