Filter by:Annually 100,000 strokes occur, placing stroke as the largest cause of disability in the UK. 90% of strokes are preventable, leading to national focus on programmes including "The National Stroke Programme" to act on preventing, treating, and improving post-stroke care. Importantly, over 25% of ischaemic stroke sufferers have previously had a Transient Ischaemic Attack (TIA), which presents the biggest concern for TIA patients. There are no measures which reliably identify TIA patients most likely to suffer a stroke. Novel biomarkers for predicting stroke are key to addressing this problem. The PREDICT-EV study aims to screen 300 TIA patients and follow them over 12-months. The investigators will determine if a novel biomarker we've identified to increase thrombotic risk (endothelial derived extracellular vesicles) and the resulting increased prothrombin time is associated with patients at highest risk of stroke.
Embolic strokes of undetermined source (ESUS) represent a subset of cryptogenic strokes that are suspected to have an occult embolic source. The risk of stroke recurrence in patients with ESUS varies between 1.9%/year and 19.0%/year depending on the prevalence of vascular risk factors. Part of the elevated recurrence rate is due to the inability to identify high-risk treatable causes such as cardiac thrombi as those found in the left atrial appendage (LAA), left atrium (LA), left ventricle (LV), valves, or aortic arch. The most frequently used diagnostic method in clinical practice to detect cardioaortic thrombi is transesophageal echocardiography (TEE). However, the relatively low availability, higher cost, and invasive nature of TEE limit its large-scale usability. In most stroke centers, patients presenting with an acute ischemic stroke or TIA undergo a tomography (CT) angiography (CTA) of the neck and intracranial vessels. This standard of care CTA (sCTA) classically includes the aortic arch, the higher portion of the ascending/descending aorta, and the rostral portion of the cardiac chambers, but does not involve the LAA, LV, or cardiac valves. A recent study performed among 300 patients with an acute ischemic stroke showed an overall LAA thrombus detection of 6.6% and 15% in patients with AF by extending the CTA 6 cm below the carina. This is an extraordinarily high prevalence of LAA compared to 0.5% to 4.8% of intracardiac thrombi identified on TEE in most previous studies. The major limitation of previous CTA and TEE studies is their observational design, so the differing prevalence of LAA thrombi could be explained by dissimilar population characteristics or selection bias. Based on the methodological limitation of prior studies and the promising role of extended CTAs (eCTA), a randomized controlled trial comparing eCTA + standard of care stroke workup vs. sCTA + standard of care stroke workup is needed.
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.
The occurrence of a transient ischemic attack (TIA) or a minor stroke is frequently assumed as a temporary and non-disabling event. Nevertheless, patients can experience subtle but meaningful impairments, including a decreased performance in activities of daily living (ADLs), a high prevalence of depression, cognitive decline, physical deficits, hearing degeneration, with implications in returning to work, social relations and activities. Additionally, it has been described a higher risk of stroke among these patients, which highlights the importance of promoting secondary prevention, soon after these acute episodes. Therefore, this pilot randomized controlled trial (RCT) aims to evaluate the feasibility and the effectiveness of a three-month multidomain intervention program, composed of five non-pharmacological components which may contribute to accelerate the return to the pre-event level of functioning in patients with TIA and minor stroke. The results may guide future clinical practices and health policies aiming to reduce the overall burden of stroke.
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%.
Transient ischemic accidents (TIA) are a frequent resort to hospitalization in the emergency department and are serious events in terms of recurrence and handicap. The organization of the "TIA sector" at CHUGA aims to facilitate on the one hand the care of the patient during his hospitalization in the emergencies and on the other hand to allow a safer discharge of the patient as well as his follow-up in ambulatory. The aim of this study is to study the feasibility of comprehensive short-term outpatient management after hospitalization in the emergencies. The research hypothesis is that 90% of patients complete all of the 10 recommended examinations for the diagnosis of TIA, analysis of its risk factors and initiation of necessary treatments, if necessary.
This is a pragmatic, multi-center, prospective, observational, non-interventional study and standing database of patients hospitalized for transient ischemic attack (TIA) or stroke in the 11 accredited adult neurology training institutions in the Philippines. Data will be collected from each patient while admitted in the hospital and until hospital discharge. Data collection for this study will span 3 years from study initiation, after which the utility of an extension or a re-implementation of the study will be assessed.
The purpose of this study was to test whether ticagrelor combined with aspirin can reduce the recurrence rate of stroke within 3 months compared with clopidogrel combined with aspirin in patients at high risk of non-disablement ischemic cerebrovascular events who carry the CYP2C19 function loss allele within 24 hours of onset.
In a randomized controlled trial the effect of 12 weeks of cross-sectorial physical exercise combined with patient education and individual follow-up session is investigated in patients with minor stroke or non-disabling stroke.
The burden of non-disabling ischemic cerebrovascular events (NICE) is significantly increased. However, few previous studies have focused on affective impairment after transient ischemic attack (TIA) and minor stroke. Stroke survivors are often described as apathetic. Even though post-stroke apathy (PSA) affects one in three stroke patients,it has not hitherto received much attention. NICE-A is a prospective study aimed to explore the association between baseline apathy and probable incident stroke in a population-based sample of TIA and minor stroke adults.
