Neurological deterioration is common after intracerebral hemorrhage (ICH). We aimed
to identify the predictors and effects of neurological deterioration and whether tranexamic
acid reduced the risk of neurological deterioration. Data from the Tranexamic acid
in IntraCerebral Hemorrhage-2 (TICH-2) randomized controlled trial were analyzed.
Neurological deterioration was defined as an increase in National Institutes of Health
Stroke Scale (NIHSS) of >= 4 or a decline in Glasgow Coma Scale of >= 2. Neurological
deterioration was considered to be early if it started <= 48 h and late if commenced
between 48 h and 7 days after onset. Logistic regression was used to identify predictors
and effects of neurological deterioration and the effect of tranexamic acid on neurological
deterioration. Of 2325 patients, 735 (31.7%) had neurological deterioration: 590 (80.3%)
occurred early and 145 (19.7%) late. Predictors of early neurological deterioration
included recruitment from the UK, previous ICH, higher admission systolic blood pressure,
higher NIHSS, shorter onset-to-CT time, larger baseline hematoma, intraventricular
hemorrhage, subarachnoid extension and antiplatelet therapy. Older age, male sex,
higher NIHSS, previous ICH and larger baseline hematoma predicted late neurological
deterioration. Neurological deterioration was independently associated with a modified
Rankin Scale of > 3 (aOR 4.98, 3.70-6.70;p < 0.001). Tranexamic acid reduced the risk
of early (aOR 0.79, 0.63-0.99;p = 0.041) but not late neurological deterioration (aOR
0.76, 0.52-1.11;p = 0.15). Larger hematoma size, intraventricular and subarachnoid
extension increased the risk of neurological deterioration. Neurological deterioration
increased the risk of death and dependency at day 90. Tranexamic acid reduced the
risk of early neurological deterioration and warrants further investigation in ICH.
