Increased levels of proinflammatory cytokines have been recorded after the onset of transient or permanent brain ischemia and are usually associated with exacerbation of ischemic injury. Embolic stroke model is more relevant to the pathophysiological situation in such patients, because the majority of ischemic injuries in humans are induced by old thrombi that originate from the heart and carot...

BACKGROUND Patients with acute cardio-embolic stroke from atrial fibrillation (AF) are at risk for recurrence with up to 50% of recurrent stroke occurring within two weeks of the index event. Anti-coagulation with heparinoids within 48 hours of stroke has been shown to increase risk of symptomatic intracranial hemorrhage (ICH) with no clear benefit on early stroke recurrence. METHODS This stu...

BACKGROUND AND PURPOSE Current research focused on stroke in the setting of coronary artery bypass graft (CABG) surgery has missed important opportunities for additional understanding by failing to consider the range of different stroke mechanisms. We developed and implemented a classification system to identify the distribution and timing of stroke subtypes. METHODS We conducted a regional s...

Background and Purpose—We sought to determine risk factors for stroke and stroke type in persons with isolated systolic hypertension (ISH). Methods—We performed proportional hazards analyses of data from the Systolic Hypertension in the Elderly Program, a double-blind, randomized, placebo-controlled trial of 4736 persons aged $60 years with ISH (systolic blood pressure, 160 to 219 mm Hg; diasto...

ischemic stroke accounts for about 87 percent of all cases. it occurs as a result of an obstruction within a vessel of the brain and sudden loss of blood circulation to the corresponding area resulting in the loss of brain function. it is caused by thrombotic or embolic occlusion of an artery and is more common than hemorrhagic stroke. we know that most of the injuries after an acute ischemic s...
