Filter by:The lack of blood flow to the small intestine causes mesenteric ischemia. Using a Superconducting QUantum Interference Device (SQUID) which measures the magnetic field of the small intestine, we are hoping to identify abnormalities without surgical intervention.
Adenosine and AMP are substances normally present in the body. Adenosine is also given for the treatment of some heart rhythm problems and may be used to reduce heart damage during heart attacks. The problem in using adenosine is that it is taken up by cells and, therefore, very little of the adenosine we give by vein or in the artery actually reaches the tissue. We propose to use AMP as a way to improve delivery of adenosine. AMP is inactive by itself, but is converted to adenosine in tissue. We hope that by giving AMP we will increase levels of adenosine in tissue. To see if this is true, we will give either adenosine or AMP into the forearm artery while we measure how much adenosine reaches the forearm tissue.
The purpose of this study is to look at the electrical activity present in healthy and diseased smooth muscle of the intestines; and develop both mathematical and computer models.
The purpose of this study is to use the Squid magnetometer (Superconducting QUantum Interference Device) to help diagnose electrical and mechanical abnormalities of the stomach and intestines.
HYPOTHESES - Discharge on the same day after uncomplicated trans-radial coronary artery stenting is safe and effective. - Hospitalized patients can be safely returned to the referring center the same day following trans-radial coronary artery stenting. - Abciximab given as a single bolus with optimal trans-radial coronary artery stenting is as safe and effective as bolus + 12 hrs perfusion and does not hamper early discharge. - Same-day discharge is cost-effective and increases patient satisfaction. OBJECTIVES AND END-POINTS The objectives of the present study are to assess the effectiveness and safety of same day hospital discharge after uncomplicated coronary artery stenting when a single bolus of Abciximab is used. The primary end-point of the study is the composite of death, myocardial infarction, repeat hospitalization, urgent revascularization, severe thrombocytopenia, access site complications and major bleedings at 30 days following stent implantation. The secondary end-point is the composite of death, myocardial infarction, repeat target vessel revascularization at 30 days, 6 months and 1 year following stent implantation. Other secondary end-points include the total hospital stay (days) between the index procedure and the first 30 days follow-up, the number of unsolicited medical visits in relation with the percutaneous procedure, index of patient satisfaction and direct and indirect costs.
The objective of ESPRIT was to compare the efficacy and safety of mild anticoagulation or a combination treatment of aspirin and dipyridamole with the efficacy and safety of treatment with aspirin alone after cerebral ischemia of arterial origin.
To demonstrate the clinical efficacy and safety of vascular endothelial growth factor(VEGF165)when delivered by direct myocardial injection through the NOGA navigational catheter to improve myocardial perfusion in patients with severe angina pectoris for whom conventional PCI or CABG are either not possible or not ideal.Secondary objective will be to determine the effects of VEGF gene therapy on angina symptoms, patient perceived quality of life and exercise capacity
The objective of study is to compare the anti-ischemic efficacy and safety profiles of once daily amlodipine or isosorbide-5-mononitrate in the treatment of stable asymptomatic and symptomatic myocardial ischemia
The primary purpose of this study is to determine whether a brief intravenous infusion of ancrod started within 6 hours of stroke onset improves functional outcome at 3 months.
The goal of this pilot study is to evaluate the effect of Vision Restoration Therapy, VRT, on the visual function of patients with unilateral or bilateral AION, who have good central vision (at least 20/60) and altitudinal visual field defects.
