Active clinical trials for "Ischemia"

It is known that several common eye diseases are associated with ocular perfusion abnormalities. Moxaverine is used in the therapy of perfusion abnormalities in the brain, the heart and the extremities because of its direct vasodilatory effects. The present study seeked to investigate whether moxaverine alters ocular blood flow in healthy volunteers after intravenous administration.

The purpose of this research study is to compare in patients with double-sided claudication if the transplant of a combination of stem cells obtained from the bone marrow of the same patient will contribute to the formation of new blood vessels in one of the severly diseased ischemic limbs(legs)versus the control limb that receives a placebo product. Limb Ischemia (LI) is a severe obstruction of the arteries which seriously decrease blood flow to the extremities (mainly feet and legs) and has progressed to the point of severe pain and even skin ulcers or sores. LI needs comprehensive treatment since the condition will not improve on its own. The overall goal of treatment is to reduce pain and increase blood flow to improve symptoms or save the leg and feet. In many cases, current options for treatment including medications, surgery or endovascular procedures have not been successful. In the last few years, investigators have explored therapies aimed to increase blood flow to the ischemic vessel by transplanting cells that will promote the development of new vessels in the diseased leg. The study hypothesis is based on the concept that the process of formation of new blood vessels is complex and requires the participation of several types of stem cells and growth factors. The lack of any of these components will produce vessels which are immature and unable to provide appropriated blood supply to the leg. Patients eligible to participate in the this study are those suffering from double-sided claudication with poor circulation or severe leg blockages, which are not candidates for surgical procedures. Once the mixture of stem cells is prepared and the patient's bone marrow is ready, cells will be transplanted into the calf muscle of one the the diseased legs while the other diseased leg will receive the placebo. Clinical study to evaluate and compare the efficacy of the stem cell transplant will be performed for six months post cell transplant.

RATIONALE: Warm ischemia is the clamping of blood vessels without cooling the kidney. Cold ischemia is the clamping of blood vessels with kidney cooling. It is not yet known whether warm ischemia is more effective than cold ischemia in patients undergoing surgery for stage I kidney cancer. PURPOSE: This randomized phase III trial is studying warm ischemia to see how well it works compared with cold ischemia during surgery in treating patients with stage I kidney cancer.

Primary Objective The main objective of this study is to assess if a two-month regimen of irbesartan in patients hospitalized for acute coronary syndrome without ST segment elevation can reduce inflammation markers (ie hsCRP), in comparison to a similar regimen of enalapril. Secondary Objectives To compare both regimens on several other biological parameters which have demonstrated their relevance and their predictive clinical value (ie BNP, microalbuminuria, troponin I …) in this patient population. To compare on the above parameters the early initiation of treatment versus the initiation of treatment at hospital discharge.

The primary objectives of the Multi MERCI trial were: to evaluate the addition of the Merci L5 Retriever additionally permit use of the Merci Retrieval System in the setting of persistent clot following IV t-PA treatment (use in the 0-8 hour window for patients ineligible for IV t-PA was also permitted)

Unprotected left main coronary artery (ULMCA) stenting, offering restoration of a native flow to left coronary artery, is the subject of intense investigations as a potential alternative to bypass surgery. The purpose of the study is to compare the short and long term results of unprotected left main stenting with coronary artery bypass surgery.

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.

To compare the Kinetics of inhibition of platelet aggregation (aggregometry) and platelet activation (flow cytometry) with different loading doses of clopidogrel To evaluate the effect on various parameters of inflammation and necrosis and the safety of these loading doses

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

Data from VA-funded studies and the broader literature indicate that chronic stable angina (CSA) is prevalent, under recognized, under treated and associated with reduced quality of life. There are substantial opportunities for improving care of patients with this debilitating and potentially fatal problem. Because primary care providers manage most patients with CSA, efforts to improve care must necessarily involve the primary care delivery system. C3P is composed of a set of interventions employing a Collaborative Care Team model, which has been shown to be effective in managing other chronic illnesses in the primary care setting.
