Active clinical trials for "Ischemia"

This a prospective observational study including patients with ST-segment elevation myocardial infarction undergoing cardiovascular magnetic resonance for clinical reason during the index hospitalization. This local registry stemmed from multi-center european registry on cardiovascular magnetic resonance

To assess the evolution of biological markers of mesenteric ischemia during ultratrail.

The investigators will examine whether administration of certain medications will decrease or prevent ischemia-reperfusion injury.

It is hypothesized that the addition of formal cardiac rehabilitation to standard care will result in long-term improvements in cardiovascular fitness and functional capacity in individuals who have suffered a transient ischemic attack (TIA) or minor stroke. Furthermore, it is proposed that the addition of cardiac rehabilitation will influence depressive symptoms and cognition.

To identify the circumstance during decision making processes to seek medical help in patients with symptoms of acute ischemic stroke.

The purpose of this study is to try and determine whether repair of moderate ischemic mitral regurgitation at the time of coronary bypass graft surgery (CABG) has an impact on survival.We will compare patients undergoing CABG + mitral repair or CABG only groups. Primary endpoints include late survival. Secondary endpoints include event free survival, symptoms, and echocardiographic outcomes.

To extend mortality followup through 25 years for two cohorts of men in the Multiple Risk Factor intervention Trial (MRFIT): the 361,662 men screened and the 12,866 men randomized, and to pursue the general aim of elucidating unresolved research issues on the epidemiology, natural history, etiology, prevention, and control of major chronic diseases, particularly cardiovascular and neoplastic diseases and diabetes.

This study will examine the health-related quality of life in patients being treated for chronic heart disease. Patients 18 years or older with chronic ischemic heart disease and left ventricular dysfunction enrolled in protocols in the National Heart Lung and Blood Institute's Cardiology Branch may participate in this study. Participants will complete five questionnaires at 3 separate times during the study-once during hospitalization at the NIH Clinical Center and again at home 6 months and 1 year later. The questionnaires, described below, require a total of about 30 minutes to complete. Demographic Information Sheet -General information such as age, marital status, employment, education, and history of cardiac medical procedures. General Health Survey -Patient's self-assessment, on a rating scale, of physical and emotional well being. Questions are related to the ability to perform work and daily living activities, mood and state of mind, limitations on social activities, energy level, pain level, general quality of life, etc. Heart Disease Survey - Patient's self-assessment, on a rating scale, of the level of physical, social, emotional and functional well being related to his or her heart condition. Questions concern fatigue level, emotional outlook, social well being, etc. Angina Survey - Information on the frequency of chest pain, chest tightness, or angina. Symptom Distress Survey - Patient's ranking of the degree of symptom distress from chest discomfort, difficulty breathing, heart rate irregularities, wheezing and coughing. All information provided in the questionnaires will be kept confidential. Upon request, patients will be sent a summary of the study results when the study is completed.

To date, no transplant has allowed pregnancy from a donor in a state of brain death. One of the main reservations lies in the ischemic properties of the uterine graft between the sampling time and the grafting time. Investigators propose to carry out a prospective monocentric study at the University Hospitals of Strasbourg in 2018/2019: the objective would be to study physiologically the time of ischemia of the uterine muscle The objective is to carry out a preparatory study on healthy uteri to study the ischemic properties of uterine muscle from living markers: study of mitochondrial respiration and free radical production on uterine muscle samples If the markers are reliable, they would then be used to measure the ischemia of whole uteri collected at the end of the multi-organ retrieval process from donors in a state of brain death and stored in tissue survival media.

Background: Acute kidney injury (AKI) is a common and serious postoperative complication in children with congenital heart disease. In this prospective cohort study, we tested the hypothesis that renal desaturation defined as a 20% decline of renal tissue oxygen saturation (SrtO2) from the baseline value is associated with AKI in infants undergoing ventricular septal defect (VSD) repair with cardiopulmonary bypass (CPB). Methods: Infants aged 1 months to 12 months and scheduled to undergo VSD repair with CPB were eligible. SrtO2 was monitored using a tissue near-infrared spectroscopy. Renal desaturation was defined as a decrease of SrtO2 measurement from the baseline value for more than 20% lasting for more than 60 s. The primary outcome was the incidence of AKI on postoperative 1-3 days according to the Kidney Disease: Improving Global Outcomes criteria. The secondary outcomes included different stages of AKI, duration of postoperative mechanical ventilation, duration of intensive care unit (ICU) and hospital stay, renal replacement therapy (RRT), and in-hospital mortality.
