Filter by:In this study, 24 prevalent hemodialysis patients will undergo four regular hemodialysis sessions during which four different treatments will be performed. - Treatment 1: MCO membrane (=medium cut off) - Treatment 2: low flux membrane - Treatment 3: high flux membrane - Treatment 4: HDF(=hemodiafiltration) treatment with high flux membrane So far, there is no data on cardiac bioenzyme levels during hemodialysis on the MCO membrane, thus, a acute elevation during hemodialysis might be mitigated by increased clearance.
This study will be investigating how a common blood test for identifying heart damage (Troponin T) is affected by red blood cell damage in the blood sample (Haemolysis). It is already known that damage to the red blood cells during or after blood sample collection can cause falsely low test results however the exact amount is not clear. Some previous studies suggest that a much higher amount of red blood cell damage could be allowable when reporting the test results. This study will mimic the type of red blood cell damage that occurs in the hospital and determine what degree of damage or 'haemolysis' causes a significant reduction in the test result and therefore determine an allowable limit for safely reporting the test result. The results of this study may help provide an evidence based approach to improving current practice and may lead to fewer rejected blood samples, fewer repeat tests, improved A&E treatment times, general cost savings and an improved service to patients.
New high-sensitivity cardiac troponin (hs-cTn) assays allow earlier detection of acute myocardial infarction (AMI). Furthermore, elevated values were associated with an increased risk of recurrent AMI or death. Therefore, guidelines recommend an early invasive strategy in patients with elevated admission values and kinetic changes. Other criteria for an early invasive strategy include a GRACE risk score >140 points or other cardiovascular risk factors. Hs-cTn assays allow discrimination of patients at very low and high risk. Studies confirmed safety of early discharge protocols in patients with unstable angina (UAP). The aim of this study is to 1) confirm the safety of early discharge without invasive strategy in patients with UAP and to 2) review the optimal timing of stress-testing. Therefore, patients are being randomized into 2 groups with pre-discharge and early post-discharge stress-testing. Endpoints are major adverse cardiovascular events within 30 and 90 days.
