5 Clinical Trials for Various Conditions
The purpose of this study is to create a state-wide biorepository and resource center for cerebrovascular diseases in Florida, which will include collecting medical history information and blood from subjects affected by cerebrovascular disease. The information and blood samples collected may be used in future research for the study of cerebrovascular disease and to learn about, prevent or treat other health problems.
Carotid Disease causes 10% of strokes. The Investigators are attempting to investigate the use of Transcranial Doppler to see if this is and effective, efficient, and/or valid way to identify individuals at highest risk for thromboembolic events from carotid disease. The plan is to plot the number of high intensity transient transcranial doppler signals with the category of patient (asymptomatic, symptomatic, and actively symptomatic) and evaluate if a relationship exists. The Investigators hypothesize that a linear relationship exists in that the higher the number of HITS the more symptomatic the patient. If results demonstrate the numbers of HITS correlate with the severity of disease this could potentially identify asymptomatic patients having subclinical symptoms who would benefit from a more urgent surgical intervention versus the current standard of care of elective intervention.
The purpose of this study is to determine whether aspiration thrombectomy following carotid stent deployment will reduce the number of procedure related signals as identified by diffusion weighted MRI of the brain.
The purpose of this study is to build upon trials done over 30 years ago, which did not include statins, new antiplatelet agents, and newer antihypertensive medications. Since the landmark trials (NASCET, ECST), there have been new developments in medical stroke prevention, which creates a gap in knowledge. The aim of this study is to evaluate that clinical care with Intensive Medical Therapy (IMT) alone, the one year stroke rate in patients with symptomatic carotid stenosis and low risk clinical features will be \<5%.
The purpose of the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST) is to compare the relatively new procedure of stent-assisted carotid angioplasty (CAS) to the traditional and accepted surgical approach of carotid endarterectomy (CEA) for the treatment of carotid artery stenosis to prevent recurrent strokes in those patients who have had a TIA (transient ischemic attack) or a mild stroke within the past 6 months (symptomatic) and in those patients who have not had any symptoms within the past 6 months (asymptomatic).
