Task: Answer Verification
Input (English): Question: Is beta-blocker use associated with lower stroke and death after carotid artery stenting?
Answer: Postprocedural hypertension and hypotension that require treatment are both strongly associated with periprocedural stroke/death after CAS. Beta blockers significantly reduce the stroke/death risk associated with carotid stenting and should be investigated prospectively for potential use during CAS.
Output (English): yes
