Filter by:The purpose of this study is to evaluate delayed myocardial protective effect of RIPC in patients undergoing cardiac valve replacement surgery.
The aim of the present study is to compare the antiarrhythmic and myocardial protective effect between lidocaine, dexmedetomidine, and their combined infusion in subjects undergoing coronary artery bypass graft.
Remote ischemic preconditioning (RIPC) with transient upper limb ischemia/reperfusion reduces myocardial injury in patients undergoing on-pump coronary artery bypass (CABG) surgery with cross-clamp fibrillation or blood cardioplegia for myocardial protection. The present study assesses protection of heart, brain and kidney by RIPC under crystalloid cardioplegic arrest. The study also addresses safety and clinical outcome.
The main focus of the project is to determine to what degree myocardial energy metabolism is linked to impaired function in human cardiomyocytes, whether exercise training and remote ischemic preconditioning can restore cardiomyocyte function and whether this is linked to improved mitochondrial and cell function.
Remote Ischemic Preconditioning (RIPC) is a treatment that may be associated with improved outcomes after cardiac surgery. It can be elicited noninvasively by using a tourniquet to elicit transient ischemia over a lower extremity. It is thought to promote anti-inflammatory and cell survival pathways, and thus protect remote organs against future ischemic injury. We hypothesize that compared to sham treatment, RIPC will be associated with decreased post-operative acute kidney, myocardial, and lung injury.
Animal studies have shown that preconditioning with hyperbaric oxygen can induce central nervous system and heart ischemic tolerance. This study was designed to determine the protective effect of hyperbaric oxygen preconditioning on brain and myocardium ischemia-reperfusion injury during coronary artery bypass graft surgery.
The purpose of this study is to determine if an intravenous anesthetic with antioxidant properties will protect the heart of diabetic patients from injury while undergoing coronary bypass surgery.
Pharmacologic preconditioning by volatile anesthetics may depend on the mode of administration. The researchers hypothesize that a continuous administration in patients scheduled for CABG surgery prebypass will be less effective in terms of attenuating myocardial cell damage compared to a repetitive administration with a double wash in/wash out schedule. A control group will receive propofol as their primary anesthetic.
Some newborns are born with congenital heart block (CHB), a condition occurring in babies with neonatal lupus. The first part of the study will test the effectiveness of fluorinated steroids, including dexamethasone, in improving the heart function and general health of newborns who have auto-antibody-associated CHB. The second part of this study will use ultrasound and heart monitoring to observe high-risk pregnant women and their fetuses during the third trimester of pregnancy.
