Active clinical trials for "Ischemia"

The primary objective of the study is to evaluate the difference in 6-month restenosis rates in coronary artery lesions treated by photopheresis in addition to angioplasty with stent placement, as opposed to no photopheresis after angioplasty and stent placement. Restenosis means the closing up again, or narrowing in diameter, of the previously treated artery, which may cause reduced blood flow and the re-occurrence of symptoms. Photopheresis is a therapeutic technique in which a portion of your white blood cells is collected by a blood separation device and exposed to ultraviolet A light, in combination with the drug 8-MOP (8-methoxypsoralen), then returned to you. The secondary objectives are: To compare the incidence of major adverse cardiac events (MACE) between the three treatment groups for 6 months post-angioplasty. MACE events include death (cardiac related), myocardial infarction, coronary artery bypass graft surgery, repeat angioplasty to the target vessel, hospitalization and clinical symptoms. To evaluate the safety of the treatment by comparing the incidence of acute and subacute thrombosis, bleeding and vascular complications and other non-MACE events every 2 weeks for 6 months post-angioplasty between the three treatment groups.

The primary purpose of this study was to assess the overall safety of different dose regimens of AMG0001 (HGF transferred via plasmid vector) as well as evaluate the improvement of blood perfusion in subjects with critical limb ischemia (CLI). This study also evaluated the improvement in wound healing without adverse effects on the quality of life, as well as the potential reduction of amputation, mortality and rest pain in the CLI population.

INDICATION Microvascular angina. OBJECTIVES To investigate the effect of ACE (angiotensin converting enzyme) inhibition (quinapril) in improving coronary microvascular function. PATIENT POPULATION Women who meet the National Heart, Lung and Blood Institute-sponsored WISE (Women Ischemia Syndrome Evaluation) study criteria of chest discomfort, coronary flow reserve limitations and evidence for myocardial ischemia in the absence of significant coronary artery stenosis. STUDY DESIGN A prospective, randomized, placebo-controlled, comparative trial. TREATMENT Quinapril 80 mg/d versus placebo for four months. PRIMARY EFFICACY PARAMETER(S) Coronary flow reserve (CFR) at Week 16 adjusted for baseline CFR, treatment group assignment, site-specific variables, and site by treatment effects. SECONDARY EFFICACY PARAMETERS Week 16 change in chest discomfort as measured by the Seattle Angina Questionnaire adjusting for baseline values, site, and site by treatment effects. SAFETY PARAMETERS Hematology, blood chemistries, blood pressure and pulse, and frequency and occurrence of adverse events. STATISTICAL RATIONALE AND ANALYSIS A statistical rationale for the number of patients in the study has been provided. Interim analyses are planned after 15 patients have been enrolled in each group. ANTICIPATED TOTAL NUMBER OF PATIENTS 78 (39 per group). ANTICIPATED NUMBER OF PATIENTS AT EACH SITE Approximately 26

To determine whether early intravenous magnesium treatment of patients with suspected acute myocardial infarction reduces mortality.

To determine the practicality, benefit, and safety of paramedic administration of thrombolytic therapy for acute myocardial infarction. The feasibility of paramedics correctly identifying candidates for thrombolytic therapy following myocardial infarction was assessed in Phase I. In Phase II, pre-hospital thrombolytic therapy was compared with in-hospital thrombolytic therapy.

The Thrombolysis in Myocardial Ischemia Trial (TIMI III) focused on unstable angina and non-Q-wave myocardial infarction. The trial was designed to determine by coronary arteriography the incidence of coronary thrombi in these conditions and the response of these thrombi to tissue-type plasminogen activator (t-PA) in TIMI IIIA and the effects of thrombolytic therapy and of an early invasive strategy on clinical outcome in TIMI IIIB. There was also a registry with two components. A roster enumerated all patients with unstable angina or non-Q-wave myocardial infarction enrolled at cooperating hospitals. From the roster, a study population of 1,893 subjects was selected and followed prospectively for the year to determine incidence of death or myocardial infarction.

To determine whether the administration of intravenous streptokinase (SK) early in the course of acute, transmural myocardial infarction would limit myocardial damage.

This large multicenter trial tested whether cerebral cooling initiated within 6 hours of birth and continued for 72 hours would reduce the risk of death and moderate to severe neurodevelopmental injury at 18-22 months corrected age. Infants at least 36 weeks gestation with an abnormal blood gas within 1 hour of birth, or a history of an acute perinatal event and a 10-min Apgar score <5, or continued need for ventilation were screened. Following a neurological exam, those with moderate to severe encephalopathy were randomized to a 72-hour period of total body cooling (cooling blanket, followed by slow re-warming). The study was conducted in two phases: Phase I (20 infants) were examined for the safety of an esophageal temperature of 34-35 C; Phase II (main trial, 200 infants) were evaluated for the safety and efficacy of an esophageal temperature of 33-34 C. Cardio-respiratory, electroencephalograms (EEGs), renal, metabolic, and hematologic status, and esophageal and abdominal skin temperature were monitored during the 72 hours of intervention. Surviving children were given neurodevelopmental examinations at 18-22 months corrected age and again at school age (6-7 years of age).

This is a Phase II study to assess the safety and tolerability of DM199 in acute ischemic stroke patients. The study will be randomized, placebo controlled at multiple centers.
