Differences Between Vascular Structural Abnormality and Hypertensive Intracerebral Hemorrhage

Area of Science:

• Neurology
• Neurosurgery
• Vascular Medicine

Background:

• The clinical characteristics and prognosis of vascular structural abnormality-related intracerebral hemorrhage (ICH) compared to hypertensive ICH are not well understood.
• This knowledge gap complicates differential diagnosis and prognosis prediction.

Purpose of the Study:

• To compare the clinical characteristics and prognosis of vascular structural abnormality-related ICH versus hypertensive ICH.
• To identify independent predictors of mortality and good outcome following ICH.

Main Methods:

• A prospective cohort study enrolled 281 patients with ICH from 50 hospitals in China.
• Patients were categorized into vascular structural abnormality-related ICH or hypertensive ICH groups.
• Demographics, clinical characteristics, and outcomes were compared using multivariate logistic regression.

Main Results:

• Vascular structural abnormality-related ICH occurred in younger patients with higher Glasgow Coma Scale (GCS) scores, primarily in lobar areas.
• Mortality at 3 months was significantly lower (3.4% vs. 15.2%) and good outcomes significantly higher (77.2% vs. 49.9%) in the vascular structural abnormality-related ICH group (P < .001).
• Independent predictors of mortality included lower GCS score, older age, intraventricular hemorrhage, larger hematoma volume, and surgery; predictors of good outcome included vascular structural abnormality etiology, higher GCS score, younger age, and smaller hematoma volume.

Conclusions:

• Patients with vascular structural abnormality-related ICH generally experience better clinical outcomes compared to those with hypertensive ICH.
• ICH etiology, GCS score, age, and hematoma volume are key independent predictors of patient outcomes.
