Study design
Intervention model description
Randomized, placebo controlled, parallel arm design
Eligibility
Inclusion criteria
* Subjects with \>= 70% carotid stenosis (unilateral or bilateral) who are scheduled to undergo elective carotid endarterectomy * Age \>= 18 years * Agreement of the operating surgeon for patient to participate
Exclusion criteria
* Surgery scheduled \< 14 days after randomization * Pregnancy * ALT, GGT \> 3x upper limit of normal (ULN) * Creatinine \> 3.5 mg/dL * Prior intolerance to statins * Reluctance to add or change dosage of statin therapy during study
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Decrease in Rho/ROCK Expression With Concordant Increase in eNOS Expression/Activity in Carotid Specimens. | >= 2 weeks | We were going to compare Rho/ROCK expression and eNOS expression/activity in carotid specimens obtained from patients treated with fasudil and compare those to specimens obtained from patients treated with placebo. We anticipated that Rho/ROCK expression and activity would be decreased in spcimens obtained from fasudil treated patients compared to specimens obtained from patients treated with placebo. We also anticipated that eNOS expression and activity would be increased in specimens obtained from patients treated with fasudil compared to specimens obtained from patients treated with placebo. |

Outcome results
Decrease in Rho/ROCK Expression With Concordant Increase in eNOS Expression/Activity in Carotid Specimens.
We were going to compare Rho/ROCK expression and eNOS expression/activity in carotid specimens obtained from patients treated with fasudil and compare those to specimens obtained from patients treated with placebo. We anticipated that Rho/ROCK expression and activity would be decreased in spcimens obtained from fasudil treated patients compared to specimens obtained from patients treated with placebo. We also anticipated that eNOS expression and activity would be increased in specimens obtained from patients treated with fasudil compared to specimens obtained from patients treated with placebo.
