Stroke, TIA
Conditions
Brief summary
In acute stroke patients about 20 % have known diabetes. There is a doubled risk of recurrent stroke in diabetic patients. It has been shown that antiplatelet drugs are not as effective in diabetic patients as in non-diabetic patients. In acute stroke patients around 80 % have impaired glucose tolerance, which will improve after one month till about 60 %. This study includes acute patients with minor stroke or TIA. They are followed up at one and six months and then at every six months for at least four years. The investigators perform an OGTT and haemostatic tests within the first days after onset and then at one month. Blood pressure, metabolic parameters, bodyweight, physical activity and diet are collected at each visit. The investigators give the patients information about lifestyle changes as needed. As part of the study there is an interventional study, Medicine Yoga, an open randomized controlled study. Patients are randomized to 16 sessions of Yoga under professional instructions and a CD for home training or controls. The aims of this study are to investigate glucose tolerance in acute stroke and TIA patients, and its relation to the different haemostatic variables. The importance of glucose tolerance, haemostatic variables and other risk factors (blood pressure, lipids, BMI,) on cardiovascular events will be investigated and the possibility to affect these risk factors by lifestyle changes and Yoga. The effect of different antiplatelet drugs will be investigated in relation to glucose tolerance.
Detailed description
144 patients with minor stroke and TIA has been included in the study between 2010 and 2012. They have been follow for four years. Two papers have been published on the results of the study.
