Active clinical trials for "Ischemia"

This is a trial of screening for ALOA-IgG AtheroAbzyme Test comparing healthy, asymptomatic myocardial ischemic and acute coronary syndrome patients.

Vascular occlusion is used to reduce blood loss during liver resection (LR), but may cause ischemic damage to the remnant liver and can lead to liver failure in case of chronic liver disease. This restriction of blood flow (ischemia) and subsequent restoration (reperfusion) causes a harm that is called ischemia- reperfusion injury. Injuries sustained during the ischemic phase are related to a lack of oxygen to reduce cellular respiratory events can lead to, in a few minutes, irreversible damage. Ischemic preconditioning as a technique to protect the liver parenchyma during liver resection consists of an initial flow clamping for 10 minutes, with subsequent reperfusion for 10-15min, followed by a complete portal triad clamping during transection.

The purpose of this trial is to find out the appropriate way to treat DM patients with critical limb ischemia. This trial includes two parts. Part I focuses on the treatment of femoral arterial lesion and part II focuses on the treatment of below-knee arterial lesion.

The objectives of the trial of a medication-coach program for patients with stroke or transient ischemic attack are to pilot test the study design, the intervention components and the data collection forms and refine them for a larger trial whose goal will be to improve long-term adherence to stroke prevention medications.

Coronary angiography via the femoral artery is regarded as a safe procedure, but bleeding complications are often seen. To avoid/reduce bleeding complications digital compression is applied in the area of puncture during approximately 20 minutes and the patient is in the investigators' department observed in bed for 2 hours. The investigators apply pressure over the puncture site using a sand bag in the first hour. The patients are told not to move, to keep their legs and upper arms down and not to lift the head from the pillow in these 2 hours (standard observation). In the present study the patients are randomized between standard observation and an alternative observation, where the patients are allowed to lift their head, arms and legs during the 2 hours, otherwise as standard observation. The study has three aims: To establish the incidence of bleeding complications: Frequency of hematoma (> 5 cm) Frequency of pseudoaneurysms Frequency of bleeding demanding surgery Frequency of bleeding demanding transfusion Establish a model to predict in wich patient to expect a bleeding complication. Assess if the alternative observation is associated with more bleeding complications compared to standard observation.

The purpose of this prospective randomized controlled trial was to compare intensive insulin therapy with a carbohydrate restrictive strategy in patients with acute ischemic stroke evaluating the outcome through the Glasgow Outcome Scale Extended, hospital mortality and NIHSS during the ICU stay.

Treatment for no-option heart patients with coronary artery disease. Procedure includes the injection into the heart of a protein growth factor, administered by the Biological Delivery Systems MyoStar injection and mapping catheters, to stimulate the growth of blood vessels around blocked coronary arteries.

The primary objective of the study is to demonstrate that SPG (Sphenopalatine Ganglion) stimulation started within 6 hours from stroke onset slows the expansion of the infarct core volume in acute ischemic stroke.

CFR has been studied for few years using 82 Rubidium PET (positron emission tomography) /CT. CFR has shown to be correlated with cardiovascular events occurring in the 10 following years. CFR also helps to identify multivessel coronary disease. Few studies have shown the possibility to calculate CFR during myocardial perfusion SPECT on new ultrafast CZT cameras.

Cerebrovascular reserve (CVR), defined as the increase in cerebral blood flow (CBF)in response to a vasodilatory stimulus, is known to reflect the compensative capacity of the brain to maintain adequate blood flow in the face of decreased perfusion due to arterial stenosis. CVR dysfunction has been identified as an independent risk factor for ischemic stroke. Limb remote ischemic preconditioning （LRIC) has been suggested as a protective therapeutic modality against brain ischemia. So it is worth to detect whether LRIC can improve the CVR ability in ischemic cerebrovascular disease patients.
