Objective
To assess the impact of blood glucose, coagulopathy, seizures and prior statin and aspirin use on clinical outcome following intracerebral hemorrhage (ICH).
Background
Intracerebral hemorrhage (ICH) accounts for 10–15% of all strokes with mortality rates approaching 50%. Glasgow Coma Scale (GCS), ICH volume, age, pulse pressure, ICH location, intraventricular hemorrhage (IVH) and hydrocephalus are known to impact 30-day survival following ICH and are included in various prediction models. The role of other clinical variables in the long-term outcome of these patients is less clear.
Methods
Records of consecutive ICH patients admitted to The Johns Hopkins Hospital from 1999 to 2006 were reviewed. Patients with ICH related to trauma or underlying lesions (e.g. brain tumors, aneurysms, arterio-venous malformations) and of infratentorial location were excluded. The impact of admission blood glucose, coagulopathy, seizures on presentation and prior statin and aspirin use on 30-day mortality and functional outcomes at discharge was assessed using dichotomized Modified Rankin Scale (dMRS) and Glasgow Outcomes scale (dGOS). Other variables known to impact outcomes that were included in the multiple logistic regression analysis were age, admission GCS, pulse pressure, ICH volume, ICH location, volume of IVH and hydrocephalus.
Results
A total of 314 patients with ICH were identified, 125 met inclusion criteria. Patients’ age ranged from 34 to 90 years (mean 63.5), 57.6 % were male. Mean ICH volume was 32.09 cc (range 1–214 cc). Following multiple logistic regression analysis, prior statin use (P = 0.05) was found to be associated with decreased mortality with a greater than 12-fold odds of survival while admission blood glucose (P = 0.023) was associated with increased 30-day mortality. Coagulopathy, seizures on presentation, and prior aspirin use had no significant impact on 30-day mortality or outcomes at discharge in our study cohort.
Conclusions
The significant association of prior statin use with decreased mortality warrants prospective evaluation of the use of statins following ICH.
