Filter by:This study is a randomized, placebo-controlled, clinical trial to evaluate whether induced whole-body hypothermia initiated between 6-24 hours of age and continued for 96 hours in infants ≥ 36 weeks gestational age with hypoxic-ischemic encephalopathy will reduce the incidence of death or disability at 18-22 months of age. The study will enroll 168 infants with signs of hypoxic-ischemic encephalopathy at 16 NICHD Neonatal Research Network sites, and randomly assign them to either receive hypothermia or participate in a non-cooled control group.
The evaluation of the efficacy of an intraportal infusion with Tacrolimus, at the time of liver graft implantation, compared to a control group without immunosuppressive intraportal infusion (Placebo: Saline solution 0.9%) with respect to the initial liver function measured by the parameters of the liver function (LFP): AST (U/L), ALT (U/L), total Bilirubin (mg/dL) and the coagulation factors: NT (%), PTT (s), INR.
The goal of the main trial was to evaluate the effect of low dose hormone replacement therapy with 1 mg norethindrone/10mcg ethinyl estradiol in postmenopausal women with a history of chest discomfort, myocardial ischemia and no obstructive CAD. For the purposes of this study as a core lab coordinating center, the investigators will be performing P31 MRS core lab analyses; hormone core lab analyses; lipid core lab analyses; glucose, insulin and HOMA core lab analyses; exercise stress test/Holter monitor core lab analyses; brachial artery reactivity test core lab analyses; full study data analyses for manuscript preparation and the writing and submission and publication of manuscript. The main trial duration: December 1999 - May 2003. The ancillary data analysis project duration: April 2006 - March 2010.
This is a pilot study to test feasibility of collection, preparation and infusion of a baby's own (autologous)umbilical cord blood in the first 14 days after birth if the baby is born with signs of brain injury.
The purpose of this study is to evaluate the efficacy and safety of ginsenoside-Rd for acute ischemic stroke.
Patients with blockage of the blood vessels that supply blood to the back of the brain, known as vertebrobasilar disease (VBD), are at risk of having a stroke or temporary symptoms of a stroke known as transient ischemic attack (TIA). The risk of repeated stroke associated with VBD may be affected by several risk factors, including the degree to which the blockage reduces the blood flow to the brain. Patients with VBD have different levels of blockage ranging from partial blockage to complete blockage, which can affect the blood flow to the brain by variable amounts. The purpose of this research is to determine if patients with symptomatic VBD who demonstrate low blood flow to the back of the brain on magnetic resonance (MR)imaging are at higher risk of developing another stroke or TIA than patients with normal blood flow.
Ischemic preconditioning (IP) has been shown in animal studies to increase the myocardial tolerance to subsequent ischemia. Our primary hypothesis is that remote IP reduces myocardial ischemic injury during PCI.
The purpose of this study is to: - evaluate the performance characteristics (sensitivity & specificity) of iodofiltic acid I-123 imaging for detection of myocardial ischemia in patients that present in the Emergency Department with suspected Acute Coronary Syndrome (ACS). - evaluate the safety of a single injection of iodofiltic acid I-123 in patients suspected of myocardial ischemia related to ACS.
Depression is commonly seen in patients with cardiovascular disorders. In recent studies it has been shown that mild to moderate depression symptoms were associated with increased likelihood of mental stress-induced myocardial ischemia (MSIMI), which is a risk factor of poor cardiac outcome. In this project, the investigators aim to assess the treatment of mental stress-induced myocardial ischemia in ischemic heart disease patients with mild to moderate depressive symptoms. This study is a six-week double-blind placebo controlled study to examine the effects of escitalopram on mental stress-induced myocardial ischemia. This study will look to show that patients with ischemic heart disease who are treated with escitalopram will exhibit a significant improvement of MSIMI at the end of week 6 compared to patients receiving placebo.
1. To evaluate the impact of ranolazine extended-release tablets in women with subendocardial ischemia due to microvascular endothelial dysfunction on myocardial ischemia (Cardiac Magnetic Resonance (CMR) extent, severity. 2. To evaluate the impact of ranolazine extended-release tablets in women with subendocardial ischemia due to microvascular endothelial dysfunction on the outcomes of angina (Seattle Angina Questionnaire (SAQ), WISE angina frequency, Duke Activity Status Inventory(DASI) and SF-36).
