Filter by:The purpose of this study is to determine how well patients undergoing carotid artery angioplasty and/or stent-supported angioplasty for the treatment of carotid artery stenosis will perform on a battery of tests to assess brain function before and after the procedure. This study will serve as a pilot project: (a) to determine incidence of neurologic/neuropsychometric change in patients undergoing carotid artery angioplasty and/or stent-supported angioplasty, and (b) to ascertain the time it takes for these changes to resolve.
The purpose of this study is to determine how well patients undergoing carotid endarterectomy will perform on a battery of tests to assess brain function before and after surgery as compared to a control group of patients undergoing spine surgery. This study will serve to: (a) determine incidence of neurologic/neuropsychometric change in patients undergoing carotid artery surgery, and (b) to ascertain the time it takes for these changes to resolve.
Patients with blockage of the blood vessels that supply blood to the back of the brain, known as vertebrobasilar disease (VBD), are at risk of having a stroke or temporary symptoms of a stroke known as transient ischemic attack (TIA). The risk of repeated stroke associated with VBD may be affected by several risk factors, including the degree to which the blockage reduces the blood flow to the brain. Patients with VBD have different levels of blockage ranging from partial blockage to complete blockage, which can affect the blood flow to the brain by variable amounts. The purpose of this research is to determine if patients with symptomatic VBD who demonstrate low blood flow to the back of the brain on magnetic resonance (MR)imaging are at higher risk of developing another stroke or TIA than patients with normal blood flow.
The aim of the proposed study is to implement and evaluate Outreach Facilitation as a means to increase the uptake of evidence-based practice for secondary prevention and management of patients with established CVD and cardiovascular risk factors, in primary care practices throughout the Champlain LHIN. This initiative centers on the use of an Outreach Facilitation Model, in which skilled health professionals known as facilitators (Practice Change Consultants) serve as an expert resource to primary care practices in three areas: a) practice performance assessment, feedback, and consensus building towards goal setting and implementation; b) clinical, technical, organizational resources and practical advice; and c) encouragement to face and move through the challenges associated with implementing system change.
The purpose of this study is to determine, in patients following a TIA, whether a 6-month case-managed exercise based multi-factorial cardiac rehabilitation program (CR), similar to those used in patients following a heart attack, can significantly improve exercise capacity, reduce cholesterol, reduce depression, and improve thinking ability.
Design: Community based randomised trial with follow up after 12 months Participants: 360 patients admitted with stroke or TIA within the past 9 months will be recruited from the wards or outpatients and randomly allocated into two groups. All patients will be visited by the specialist nurse at home at baseline when she will measure their BP and administer a questionnaire. The questionnaire and BP will be repeated at 12 months follow-up by another researcher blind as to whether the patient is in intervention or control group. Intervention: Intervention patients will be given a validated home BP monitor and support from the specialist nurse. Control patients will continue with usual care (BP monitoring by their practice). Main outcome measures in both groups after 12months: 1.Change in systolic BP 2.Cost effectiveness: Incremental cost of the intervention to the NHS and incremental cost per quality adjusted life year gained. Study hypothesis. Home blood pressure monitoring with nurse support wil lead to lower blood pressure after 12 months compared with usual GP care
Patients with stroke or transient ischemic attack (TIA) are at high risk of poor outcome, recurrence of cardiovascular events or vascular death.Until now, no reliable predictive biological marker could be identified in the acute phase of stroke.We hypothese that, in the acute phase of ischemic stroke or TIA, the increase of cardiac ( brain natriuretic peptide, BNP) or renal markers (albuminuria, cystatin C)might predict recurrence of cardiovascular events or vascular death. We want to assess which one of these markers has the best prognosis value , in a prospective study of 300 stroke patients followed during 3 years.
Sodium imbalance is common and an adverse prognostic factor in hospitalized patients. However, identifying the causes of sodium imbalance is challenging in clinical practice. Levels of antidiuretic hormone (ADH) are elevated in patients with stroke correlating with disease severity and stress level; however, its measurement is cumbersome. ADH is derived from a larger precursor peptide along with Copeptin, which is a more stable peptide directly mirroring the production of ADH. Copeptin can be assayed readily in plasma. Early prognostic factors to predict in-hospital mortality and medium/long-term outcome in critically ill neurological patients, are helpful to guide and tailor early decisions on treatment, discharge from the intensive care unit and application of interventions to prevent deterioration of neurological functions. We hypothesize that copeptin will improve the diagnostic accuracy to diagnose sodium imbalances as compared to routinely used markers Furthermore, we hypothesize that Copeptin will be a reliable prognostic tool, dependent or independent of sodium imbalance, to predict short-term (i.e. in-hospital) and medium-term (i.e. 3 months) clinical outcome in stroke patients.
The purpose of this study is to develop and evaluate the local adaptation of existing stroke prevention tools into practice. A stroke prevention program is a collection of materials including written materials like pamphlets and brochures, videotapes and training guides for stroke survivors and evidence based guidelines for the doctors that provide care for them. Other tools that may be used in a stroke prevention program include devices that help patients monitor medical symptoms at home like home blood pressure machines or blood sugar monitors and messaging devices that allow reporting symptoms from home to a health care provider. We hypothesized Veterans with stroke who receive the Veteran Stroke Prevention Program would engage in better medication compliance and stroke specific quality of life compared to those who did not receive the program.
The primary objective of this study is to determine if emergency department patients with Transient Ischemic Attack (TIA) that are managed using a TIA "accelerated diagnostic protocol", or "ADP", demonstrate a significant decrease in their index visit length of stay and cost, with comparable diagnostic and 90-day clinical outcomes relative to TIA patients randomized to traditional inpatient care. The secondary objectives are to evaluate the potential role of a TIA risk stratification tool and to determine the time to a diagnostic endpoint in both groups.
