Active clinical trials for "Ischemic Stroke"

Evaluate the effectiveness of the of kallikrein in the different drug frequency for acute anterior circulation cerebral infarction.

The manipulation of blood pressure in acute cerebral ischemia has been a matter of debate until now. The investigators are clearly in need of more detailed data on how antihypertensive treatment affects outcome in acute phase of stroke. This study will assess the effects of modest blood pressure (BP) lowering manipulation in acute period of ischemic stroke on death or dependency at 90-day.

Mild hypothermia improves outcome in patients with global cerebral ischemia after cardiac arrest. Hypothermia seems promising also in other acute hypoxic-ischemic or in brain swelling associated cerebrovascular disease. The narrow-time-frame is a major issue ("time is brain"). To provide immediate cooling without delay, easy to use, mobile and effective methods are needed. Cold infusions (4 °C) are an accepted standard worldwide. EMCOOLS Flex.Pads (Emergency Medical Cooling Systems AG, Wien, Austria) is a new non-invasive surface cooling system. A comparison of these two induction methods has never been done before. Neither was the effect of EMCOOLS Flex.Pads on brain-temperature measured. For the first time iCOOL 2 compares feasibility, safety and efficacy of the two methods.

The purpose of this study is to evaluate the safety and efficacy of the induced hypertension using phenylephrine in patients with noncardioembolic ischemic stroke. The investigators hypothesized that phenylephrine induced-hypertension can result in good clinical response without serious complications in patients with noncardioembolic ischemic stroke.

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.

Aspirin is the only anti-platelet medication used at the acute phase of ischemic stroke. The investigators would like to study laboratory effect of the first oral 300 mg dose of aspirin, given at hospital, after an ischemic event. The principal hypothesis is that platelet activity would be able to recover during this day and could lead to ischemic recurrences. Two blood samples are accomplished. The first 2 hours after aspirin intake and the second 23 hours after. Photometric aggregometry are performed with arachidonic acid and collagen induced platelet aggregation, measure of thromboxan B2 levels and reticular platelets count.

The present study is designed to confirm the therapeutic effects of heat-clearing and blood-activating Chinese medicinal components in treatment of Acute Cerebral Infarction (ACI) and to investigate the therapeutic mechanisms of multi-target anti-inflammatory action involved from the standpoint of pathology, cell and molecular biology, as well as immunology.

This study evaluated the feasibility and acceptability of using a SystemCHANGE intervention in older adult stroke survivors to improve medication adherence. Half the participants will receive the SystemCHANGE intervention, while the other half will receive the attention-control education intervention.

This study seeks to investigate the capillary index score (CIS) to further improve patient selection of endovascular treatment (EVT) in acute ischemic stroke (AIS). The hypothesis or idea being tested: Patients with favorable CIS who are successfully revascularized with EVT can have successful outcomes with an extended time window for treatment.

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.
