Carotid Artery Disease Clinical Trials

This research is directed at a major stroke source, the carotid artery, a major vessel that supplies blood to the brain. It has long been known that carotid narrowing is an important stroke risk factor. However, many patients with narrow carotids do not have strokes, and many patients with seemingly ...

All participants will receive a one time Carotid contrast-enhanced Ultrasound (CEUS) examination that may take 30-60 minutes. Follow up calls will be made to the Participants at 6, 12 ,24 and 36 months to ask about occurrence of major adverse cardiovascular events.

Carotid artery stenting (CAS) is an emerging treatment for atherosclerotic carotid stenosis. The main adverse event is embolic stroke during the procedure. Current medical management to prevent peri-procedural embolisation consists of dual antiplatelet therapy with clopidogrel and aspirin. Ticagrelor, a novel reversible inhibitor of the platelet adenosine diphosphate receptor P2Y12, ...

The study is being done to assess the ability of the radiotracer 99mTc-rhAnnexin V-128 to image atherosclerotic plaque that may rupture and break off artery walls. This is caused by apoptosis or cell death in the plaque. These ruptured plaques can block blood circulation in the arteries causing a lack ...

Patients suffering from symptomatic carotid artery stenosis, transient ischemic attacks (TIAs), amaurosis fugax or stroke receive either Revacept (single dose) plus antiplatelet monotherapy or monotherapy alone. Patients receive a single dose of trial medication by intravenous infusion for 20 minutes. Patients are followed up one and three days after treatment, ...

To evaluate the causal relationship between Rho/Rho kinase overactivity and mechanisms of vascular dysfunction in patients with atherosclerosis.
