Objective: A study was undertaken to assess whether cerebral small vessel disease (SVD) computed tomographic (CT) biomarkers are associated with long‐term outcome after intracerebral hemorrhage.
Methods: We performed a prospective, community‐based cohort study of adults diagnosed with spontaneous intracerebral hemorrhage between June 1, 2010 & May 31, 2013.
A neuroradiologist rated the diagnostic brain CT for acute intracerebral hemorrhage features & SVD biomarkers.
We used severity of white matter lucencies & cerebral atrophy, & the number of lacunes to calculate the CT SVD score.
We assessed the association between CT SVD biomarkers & either death, or death or dependence (modified Rankin Scale scores = 4–6) 1 year after first‐ever intracerebral hemorrhage using logistic regression, adjusting for known predictors of outcome.
Results: Within 1 year of intracerebral hemorrhage, 224 (56%) of 402 patients died.
In separate models, 1‐year death was associated with severe atrophy (adjusted odds ratio [aOR] = 2.54, 95% confidence interval [CI] = 1.44–4.49, p = 0.001) but not lacunes or severe white matter lucencies, & CT SVD sum score ≥ 1 (aOR = 2.50, 95% CI = 1.40–4.45, p = 0.002).
Two hundred seventy‐seven (73%) of 378 patients with modified Rankin Scale data were dead or dependent at 1 year.
In separate models, 1‐year death or dependence was associated with severe atrophy (aOR = 3.67, 95% CI = 1.71–7.89, p = 0.001) & severe white matter lucencies (aOR = 2.18, 95% CI = 1.06–4.51, p = 0.035) but not lacunes, & CT SVD sum score ≥ 1 (aOR = 2.81, 95% CI = 1.45–5.46, p = 0.002).
Interpretation: SVD biomarkers on the diagnostic brain CT are associated with 1‐year death & dependence after intracerebral hemorrhage, independent of known predictors of outcome. ANN NEUROL 2020
