- Admission anaemia was an independent predictor of poor clinical outcome in patients with cerebral venous thrombosis (CVT).
Why this matters
- Findings warrant further studies to determine whether a causal relationship underlies this association and whether increasing haemoglobin levels improves clinical outcome.
- Study evaluated the association between anaemia and poor clinical outcomes in 952 patients with CVT.
- Definition of anaemia was made according to World Health Organization criteria.
- Poor clinical outcomes (modified Rankin Scale [mRS] score, 3-6), mortality and mRS 0-1 were evaluated.
- Funding: None disclosed.
- Of 874 patients with CVT, 22% had anaemia at admission.
- Compared with patients without anaemia, those with anaemia more often had:
- history of cancer (17% vs 7%; P<.001>
- reported coma (11% vs 5%; P=.001) and
- non-haemorrhagic parenchymal lesions (44% vs 30%; P<.001>
- Exclusion 8% patients with CVT because of missing baseline haemoglobin data.
- Retrospective design.
