Predicting hemorrhage expansion in patients with hypertensive intracerebral hemorrhage: the HE-VSD-A2TP score.

Background: Hematoma expansion (HE) in hypertensive intracerebral hemorrhage (HICH) is significantly associated with patient mortality. Early identification of HE would be planning for appropriate and aggressive management for improving outcome and containing HE. Existing HE prediction models show variable accuracy across settings. To address this limitation, we developed and validate a new predictive model to enhance the accuracy of HE in patients with HICH. Methods: We conducted a retrospective cohort study using data from two centers. The primary outcome was the occurrence of HE within 24 h of symptom onset, defined as an increase in hematoma volume ≥33% or ≥12.5 mL on follow-up imaging. Logistic regression was used to identify independent predictors of HE, and the HE-VSD-A Results: Five hundred and sixty seven patients in the derivation cohort and 378 patients in the validation cohort. The HE-VSD-A Conclusion: The HE-VSD-A2TP score was validated to be an effective tool for identifying patients at risk of HE in patients with HICH. It was a valuable tool for guiding clinical management strategies and potentially improving patient outcomes.
