Group M1 - DZNE-2025-01097 SP - 828 - 839 PY - 2025 AB - Patients with lobar intracerebral haemorrhage and MRI biomarkers of cerebral amyloid angiopathy have a greater risk of recurrent intracerebral haemorrhage than patients without these biomarkers. However, access to MRI is limited. We aimed to determine whether the Edinburgh CT-only and CT-APOE diagnostic criteria for cerebral amyloid angiopathy-related lobar intracerebral haemorrhage are associated with recurrent intracerebral haemorrhage.We did a meta-analysis of individual patient data from cohort studies identified at the 2018 International cerebral amyloid angiopathy conference in Lille, France, assessing patients with lobar intracerebral haemorrhage with available diagnostic CT imaging that had been, or could be, rated for the Edinburgh cerebral amyloid angiopathy criteria imaging features, and with follow-up data for recurrent intracerebral haemorrhage and death. Eligible patients were aged 16 years or older with first or recurrent spontaneous lobar intracerebral haemorrhage diagnosed by non-contrast brain CT, with no evidence of an underlying cause other than cerebral small vessel disease. Collaborators provided individual patient-level data. The primary outcome was first recurrent intracerebral haemorrhage occurring at least 30 days after the index event, analysed using primary two-stage (cohort-level) and secondary one-stage (pooled) meta-analyses with multivariable regression models with a competing risk of death, adjusted for age, sex, and CT small vessel disease score. Pooled analyses were adjusted for previous intracerebral haemorrhage, dementia, hypertension, and cohort clustering. All analyses were done in R Project for Statistical Computing (version 4.5.0).We included eight cohorts from Austria, France, Germany, Italy, the UK, and the USA, with 1705 eligible patients for the CT-only criteria. In the primary two-stage meta-analysis of the CT-only criteria (562 patients from three European cohorts, median age 76 years [IQR 68-82], 282 [50 KW - Humans KW - Cerebral Amyloid Angiopathy: genetics KW - Cerebral Amyloid Angiopathy: diagnostic imaging KW - Cerebral Amyloid Angiopathy: complications KW - Cerebral Amyloid Angiopathy: diagnosis KW - Cerebral Hemorrhage: diagnostic imaging KW - Cerebral Hemorrhage: genetics KW - Cerebral Hemorrhage: etiology KW - Recurrence KW - Male KW - Female KW - Tomography, X-Ray Computed KW - Aged KW - Middle Aged KW - Cohort Studies KW - Aged, 80 and over KW - Apolipoproteins E: genetics KW - Apolipoproteins E (NLM Chemicals) LB - PUB:(DE-HGF)16 C6 - pmid:40975099 DO - DOI:10.1016/S1474-4422(25)00285-6 UR - https://pub.dzne.de/record/281350 ER -
