Filter by:There are evidence that there is an association between insulin resistance and prolonged hyperinsulinemia or hyperglycemia in Type 2 diabetic patients. This will trigger oxidative stress system via reactive oxygen species (ROS) and lead to a high level of Nitric oxide. This can contribute to a significant change in blood vessel and could end up with the complications from cardiovascular disease and increased mortality rate of type 2 diabetic patients. The purpose of the present study was to examine the effectiveness of the curcumin in type 2 diabetic patients on the reduction of atherosclerosis events by examining pulse-wave velocity (PWV) and plasma high-sensitivity C-reactive protein (CRP) test and on blood sugar lowering, glycosylated hemoglobin (HBA1c), lipid profile, and insulin resistance.
The goal of this study is to find out if giving intravenous B-vitamins before general anesthesia with nitrous oxide prevents the increase in homocysteine, a metabolite that has been linked to cardiovascular complications.
This research proposal has two main objectives. The first is to increase understanding of the underlying physiological interactions that occur between the cardiovascular, pulmonary, and ANS during transition between positive pressure mechanical ventilation (MV) and spontaneous breathing. The second is to determine if heart rate variability, (HRV) a reflection of autonomic nervous system (ANS) activity, and autonomic information flow (AIF), a set of nonlinear measures derived from HRV, both measured in the intensive care unit (ICU) can predict patient outcomes including successful weaning and in-hospital recovery time after an episode of cardiopulmonary compromise requiring MV. Hypothesis 1. Transitions between mechanically supported ventilation and spontaneous breathing will disturb cardiovascular synchrony, altering the relationship of HRV, AIF, respiratory rate, and blood pressure; Hypothesis 2. More normal HRV and AIF values, measured during baseline MV and sedation awakening (a period immediately prior to SBT when sedative medications are discontinued) will be associated with easier weaning, and shorter intensive care unit (ICU) and hospital lengths of stay; more abnormal measurements will be associated with longer lengths of stay; Hypothesis 3. AIF is a more sensitive predictor of successful weaning from MV than HRV.
Impaired kidney function is associated with a poor outcome in patients with heart failure but it is not known of this is the case for patients who have been born with their heart condition (congenital heart disease). This study aims to investigate how frequently patients with congenital heart disease have kidney disease and whither this does have an impact on their outcome. The hypothesis is that kidney dysfunction will be common in these patients and may have an impact on long-term health and life-expectancy.
This Protocol is intended to facilitate development and testing of new cardiovascular MRI software capabilities by UC Davis Research Faculty, as well as to facilitate the evaluation of new software capabilities provided by GE and Siemens.
This study will measure the efficacy and safety of an early postoperative anticoagulation self-management program, using the CoaguChek S device, in patients undergoing mechanical valve replacements. Patients will be randomized into a study group (self-management) or a control group (physician management).
We believe that certain cells in the human body (Circulating Endothelial Cells and Endothelial Progenitor Cells) are related to risk of cardiovascular disease. It may be possible to measure levels of these cells in patients who have had a kidney transplant and predict their risk of developing cardiovascular disease.
The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Magnevist (the study drug) used for MRI of the aortic arch and cerebral branches. The results will be compared to the results of MRI taken without Magnevist, and with the results of your X-ray angiography.
The purpose of this study is to review the use of diverticulopexy, and collect data regarding the ease of the procedure and the overall outcome.
