Filter by:The purpose of this study is to determine the effects of the Doctormate device, a specialized blood pressure cuff used to perform remote limb ischemic conditioning, on cerebral blood flow in subjects with intracranial atherosclerosis. Previous studies in patients with narrowing of the brain arteries have shown that this device is safe to use and suggested that if this device is inflated in both arms for 5 minutes, followed by deflation for 5 minutes and repeated 4 times in a row every day for 6-9 months, the risk of another stroke is lowered and the device may increase the blood flow to the brain.
Our study aims to explore the value of new imaging technique package in predicting early neurological deterioration (END) as well as 90-day unfavorable outcome in patients with acute ischaemic stroke.
The incidence of stroke has increased by 100% in the last four decades in developing countries like Pakistan. Intracranial atherosclerotic disease (ICAD) is the most frequent causative subtype of ischemic stroke in the world including Pakistan. ICAD is progressive narrowing of the arteries at the base of the brain due to atherosclerosis. After a stroke from ICAD, recurrence rate is highest in any sub-type of stroke, up to 28% with limited therapeutic options. Therefore, it is imperative to delineate the determinants of asymptomatic ICAD prior to stroke. Investigators hypothesized that there is at least a 20% difference in the proportion of clinical, life-style (dietary, physical activity, obesity, smoking and stress/depression), and socio-economic predictors of asymptomatic ICAD than those with no ICAD.
The primary objective of this study is to evaluate the rate of stroke and/or death in patients treated with the Wingspan Stent System, according to the Indications for Use, within 72 hours post procedure.
The purpose of the study is to examine if blood flow in the brain before coronary artery bypass graft surgery has an effect on depression after surgery. The main hypothesis of the study states that pre-surgical blood flow in the brain will be an independent risk factor for depression after surgery after adjusting for other risk factors such as gender, pre-CABG depression, social support, medical comorbidity burden, socioeconomic status, and neuroticism.
Stroke due to intracranial arterial atherosclerosis is a significant medical problem, carrying one of the highest rates of recurrent stroke despite best medical therapy, with annual recurrence rates as elevated as 25% in high risk groups. The goal of this investigation is to advance a promising surgical treatment for symptomatic atherosclerotic intracranial stenosis - encephaloduroarteriosynangiosis (EDAS). The investigation will test in a phase II futility trial the potential of EDAS for further development before proceeding with the design of a definitive clinical trial of EDAS Revascularization in patients with Symptomatic Intracranial Arterial Stenosis (ERSIAS). The investigation is a 4-year futility trial to test the hypothesis that EDAS revascularization combined with aggressive medical therapy warrants further evaluation in a subsequent pivotal trial as an alternative to aggressive medical management alone for preventing the primary endpoint of stroke or death in patients with symptomatic intracranial arterial stenosis (Specific Aim 1). During the investigation the time course of collateralogenesis and perfusion improvement following EDAS will also be evaluated (Specific Aim 2.
The IRISS study is designed to collect clinical and angiographic outcomes data when stenting intracranial atherosclerotic lesions using the Wingspan™ Stent System with Gateway™ PTA Balloon Catheter in routine clinical practice.
Randomized, control, open label, multicentre clinical study. The patient who are in accordance with subject inclusion and exclusion criteria will be randomized to A group: Routine treatment B group: Routine treatment+ Cilostazol; C group : Routine treatment + Probucol; D group: Routine treatment+ Cilostazol+ Probucol .
The purpose of this study is to determine whether morbidity and mortality for high-risk surgical patients treated with the Carotid Wallstent in conjunction with the FilterWire EX and EZ System distal protection device will be less than or equal to that of objective performance criteria (OPC) derived from historic controls undergoing surgical intervention with a carotid endarterectomy (CEA).
PLEASE NOTE: THIS STUDY IS ONLY ENROLLING PATIENTS CURRENTLY BEING TREATED AT BELAIR-EDISON FAMILY HEALTH CENTER. The purpose of this study is to compare the clinical effectiveness and cost effectiveness of two cardiovascular risk reduction programs - a comprehensive intensive (Cl) intervention with a less intensive (LI) intervention - in African American, and white low-income patients with known excessive cardiovascular disease risk.
