View clinical trials related to Aortic Aneurysm.
Filter by:We aimed to see if aortic aneurysms could be followed-up by circulating endothelial progenitor cells CD34+144+CD14- and CD34+VEGF-R2+CD14- blood level.
Circulating endothelial progenitor cells CD34+144+CD14- et CD34+VEGF-R2+CD14- have been shown to be inversely correlated to aortic aneurysm size. However reference values have not yet been determined. This study is aimed to determine reference values of CD34+144+CD14- et CD34+VEGF-R2+CD14- in healthy men and women blood donors.
To investigate the influence of limb remote ischemic preconditioning (LRIP) on mortality, hospitalization costs and quality of life in patients undergoing open infrarenal abdominal aortic aneurysm (AAA) repair.
Diabetes Mellitus (DM) is frequently appearing in patients with cardiovascular disease and these patients, as a consequence herby, has a lesser prognosis. DM is often related to increased arterial stiffness and hypertension. The investigators thesis is that DM and pre-diabetes is prevalent in patients undergoing cardiovascular surgery and to some extend is under-diagnosed. At the same time the investigators imagine that DM is closely related to the degree of arterial stiffness, and that these parameters are closely related to a new biochemical marker, fibulin-1. The investigators aim to describe the prevalence of type 2 DM and dysmetabolism in patients admitted to the hospital to undergo cardiovascular surgery and besides that to investigate if there is a connection between the degree of the dysmetabolism and arterial disease, by studying arterial stiffness and by measuring a new biochemical marker, fibulin-1, which the investigators newly have identified. The results of this project will give us a measure for the quantity of unknown DM in patients undergoing cardiovascular surgery and furthermore tell us more in terms of the connections between a newly identified plasma arterial marker, arterial stiffness and diabetes.
The study is based on the premise that ultrasound is not commonly used in an ambulance. There are some departments that do deploy it into the field, but of those departments there is almost no data collected about its use. Currently Paramedics are not recognized by insurance companies as health care providers capable of performing ultrasound. If there were more data on the subject that may eventually change. We are hoping to prove that not only is ultrasound useful in an ambulance, but that paramedics are good at interpreting the results. We will save images, the paramedic's diagnosis and some basic information about the call. We will not save any protected health information (PHI) or any information linking the subject to the study. The data collected will be sent to a non-biased ultrasound reviewer to grade the images for the accuracy of diagnosis and the quality of the view obtained. This data will be used to formulate a report and statistics on paramedic's ability to perform ultrasound in the field.
Objectives. To study the feasibility of an expertise-based randomized controlled trial (RCT) testing the role of traditional surgery (OPEN) versus endovascular repair (EVAR) for abdominal aortic aneurysms (AAA). Study design. We will conduct an expertise-based RCT comparing OPEN to EVAR of non-urgent abdominal aortic aneurysms in patients referred to vascular surgeons practicing at Hamilton Health Sciences, to determine the rate of death and other complications. Quality of life and status at 6 months will also be recorded. The ultimate goal is to determine the feasibility of conducting a pragmatic expertise-based RCT and to inform a future larger study at a national level.
