The level of narrowing, whether symptoms such as a transient ischemic attack (TIA) have occurred, the patient's age and health, and other risk factors all influence treatment decisions. Understanding blocked carotid artery and stroke risk can help patients recognize why timely assessment and appropriate prevention matter. Quick Takeaways Key Takeaway: Carotid artery narrowing can increase the risk of ischemic stroke, particularly when plaque or a clot interferes with blood flow to the brain.
