Condition: Heart Disease / Carotid Artery Stenosis
Investigator: Anthony Pucillo, MD
Status: Closed
This clinical trial is for patients diagnosed with carotid artery stenosis that are at high risk of a stroke. Carotid artery stenosis develops as a result of plaque buildup in the carotid artery. Over time plaque buildup creates a narrowing of the carotid artery, restricting the flow of blood. Thus, increasing the risk of stroke. In this research study the…
