Use of Simvastatin for the Prevention of Vasospasm in Aneurysmal Subarachnoid Hemorrhage
- Conditions
- Aneurysmal Subarachnoid HemorrhageCerebral Vasospasm
- Interventions
- Registration Number
- NCT00487461
- Lead Sponsor
- University of Illinois at Chicago
- Brief Summary
The purpose of this study is to test whether treatment with a drug called Simvastatin prevents and improves outcome in patients who have Subarachnoid bleeding. Simvastatin is currently approved for the treatment of high cholesterol levels.
- Detailed Description
Aneurysmal Subarachnoid hemorrhage or SAH (bleeding on the surface of the brain) affects 10 per 100,000 population each year. For survivors of the initial hemorrhage, delayed narrowing of the blood vessels (vasospasm) and related delayed strokes are the most common serious complication. Narrowing of blood vessels affect 30% of patients with such bleeding. Despite maximum therapy, nearly 50% of patients with symptomatic vasospasm with develop stroke. Because cerebral vasospasm remains the leading cause of morbidity and mortality after aSAH, this critically important issue needs further studies.
One hundred and fifty patients will be randomized, 50 to each arm of the study. Patients enrolled in the study will be receive the drug (either Simvastatin 40 mg or Simvastatin 80 mg per mouth daily), while the control group will receive a sugar tablet. The treatment will be continued for a total of 21 days. The neurological abilities (Stroke Outcome measures, these are included with the application for your review) at day 21 post aSAH will be reviewed at time of discharge as well at 6 months of follow up.

- Primary Outcome Measures
Name Time Method To Measure Outcome in Patients Diagnosed With Aneurysmal Subarachnoid Hemorrhage (aSAH) Treated With Simvastatin, by Assessing Neurological Outcome by Accessing Glasgow Outcome Score, Modified Rankin Scale, and Barthel Index Score at Day 21 Post aSAH 21 days
- Secondary Outcome Measures
Name Time Method To Determine Efficiency of Simvastatin in Decreasing the Incidence of Clinical Vasospasm in aSAH, and Define the Optimal Dose of Simvastatin and to Measure Outcome at 6 Months Follow up 6 months Study PI left before the efficacy of Simvastatin decreasing the incidence of clinical vasospasm in aSAH, and defining the optimal dose of Simvastatin and measuring the outcome at 6 months follow up data was collected for the study and therefore these outcomes will never be analyzed.
