Active clinical trials for "Cerebral Infarction"

Even if it is a daily questioning for the stroke physician, no concrete recommendation exists regarding the time-point of the mobilization of stroke patients. In this study, we will compare two mobilisation strategies: early versus delayed "verticalisation". 400 ischemic stroke patients will be included in this prospective randomized controlled trial, equally distributed in two groups. In the early mobilisation procedure the patient is allowed to go and sit outside of the bed the day after the stroke onset, whereas in the other arm, this procedure is delayed to the third day after stroke onset. The outcome in both groups will be assessed by the modified Rankin Scale at 3 months, which is commonly used in stroke study to investigate the functional outcome of the patients.

Personalized therapy as prophylaxis in ischemic stroke patients is not yet an option. From patients with ischemic heart disease, we know that patients with in vitro high on treatment platelet reactivity (HTPR) have an increased risk of stent thrombosis following per-cutaneous coronary intervention. Other studies have shown association of CYP2C19 genotypes with different responses to the anti platelet drug Clopidogrel. We measure HTPR in ischemic stroke patients on increasing doses of clopidogrel and investigate the CYP2C19 genotype for each patient.

Thoracic endovascular repair (TEVAR) and transcatheter aortic valve implantation (TAVI) are standard of care procedures to treat thoracic aortic aneurysm or severe aortic stenosis, respectively. Both procedures have a high risk of stroke and silent infarction. Gas has been detected in the cerebral vasculature during these procedures and associated with DWI positive lesions on MRI. The hypothesis is that air emboli contribute to stroke and silent infarction. The investigators propose addressing air emboli by flushing the device with carbon dioxide prior to flushing with saline. This is a pilot study comparing standard saline flush alone to carbon dioxide flushing with saline flush.

Sleep Apnea Syndrome (SAS) is highly prevalent in acute stroke and it is related to worst outcome. We aim to assess if SAS treatment, started immediately after acute ischemic stroke, impacts infarct growing and clinical prognosis.

Ischemic stroke is a kind of common disease with great harm. In acute stage of stroke there is sharply increasing morbidity of sleep apnea hypopnea syndrome. Our suppose that treatment with noninvasive ventilation for patients with acute ischemic stroke should improve the functional prognosis（measuring with 90d modified Rankin score）.

This is a prospective study including acute ischemic stroke patients aged 18 to 90. Multidetector raw CT is performed in acute ischemic stroke patients. Heart, neck vessels and brain arteries are studied during the same acquisition. Results are compared with the standard methods including transesophageal echocardiography (TEE), Doppler ultrasound (DUS) and MR angiography (MRA) of neck vessels. The main criteria is the ability of CT to classify the stroke etiology correctly according to the TOAST classification in comparison with the standard methods.

The study design is subject to relevant SFDA regulations about clinical trials. This indication was approved in Japan in 2003. From the end of May 2004 to the end of Dec. 2004, 720 patients with previous cerebral infarction(see the inclusion criteria) were enrolled in to the study and received one of the two treatment regimens, Cilostazol or Aspirin, the ratio of patient number of each group is 1:1. For each patient, the chance of entering either of these two groups is the same. The treatment will continue till the end of 2005. During the treatment period, patients will be observed concerning some certain events, mainly reoccurrence of stroke. If the patient experiences reoccurrence of stroke, or other event that the doctors think it is not appropriate to continue the study medication, this patient would stop the treatment. Patients were also required to take MRI head scan before entering the study and on completion of the treatment.

The purpose of the study is to compare two surgical strategies for coronary artery bypass grafting with respect to the occurrence of cerebral infarctions made visible by magnetic resonance imaging

This is a biomedical, single-center, and prospective study of a consecutive patients cohort in acute ischemic stroke with carotid plaque.

The primary objective of this study is to evaluate whether, in patients with first-ever atherothrombotic or lacunar stroke without any previous history of atrial fibrillation (AF)/atrial flutter (AFL)/atrial tachycardia (AT), the detection of AF/AFL/AT (silent or symptomatic) by using a continuous cardiac rhythm monitoring with implantable loop recorder (ILR) during the first 12 months of observation is higher than the detection by using a standard cardiac monitoring (physical exam, 12-lead electrocardiogram [ECG] at baseline, 3, 6, and 12 months and Holter ECG at 3 months) in the same period of time.
