Biomarker Profiling in Abdominal Aortic Aneurysm Patients

BIOMArCS-AAA
Start date: March 23, 2017
Phase:
Study type: Observational

The BIOMArCS-AAA study aims to investigate the associations of (temporal patterns of) blood biomarkers with aneurysm growth in patients with abdominal aortic aneurysm (AAA), with particular attention to biomarkers that have demonstrated prognostic value for adverse disease outcomes in coronary artery disease and biomarkers for the main genetic pathways associated with AAA.

Non-invasive Monitoring of Endovascular Repair of Abdominal Aortic Aneurysm (VBA)

Start date: April 8, 2018
Phase:
Study type: Observational

This study evaluates a novel noninvasive method to dynamically monitor the effect of abdominal aortic aneurysm (AAA) and endovascular treatment of AAA (EVAR) on arterial pulse wave

NCT ID: NCT03449875 Completed - Clinical trials for Abdominal Aortic Aneurysm

Global Post-market Registry for the Treovance Stent-graft.

RATIONALE
Start date: February 5, 2014
Phase: N/A
Study type: Observational [Patient Registry]

Patients with abdominal aortic aneurysms (AAA) suitable for endovascular aortic repair (EVAR) with Treovance were eligible to participate. Main inclusion criteria were: age 18-85 years; infrarenal AAA without significant infrarenal or distal iliac landing neck calcification or thrombus formation; infrarenal or distal iliac landing neck size requirements specified in the instructions for use. Main exclusion criteria: dissection/ruptured aneurysm or prior AAA endovascular or surgical repair. The primary endpoints were standard EVAR criteria.

NCT ID: NCT03429647 Completed - Clinical trials for Abdominal Aortic Aneurysm

Intraoperative Perfusion Patterns of the Sigmoid Colon During Elective Open Abdominal Aortic Aneurysm Repair

Start date: January 1, 2013
Phase: N/A
Study type: Interventional

Blood supply to the sigmoid colon during open abdominal aortic aneurysm (AAA) repair is at risk. Ischemia of the sigmoid colon after AAA repair is potentially devastative. No reliable measures to prevent it are available and the underlying mechanisms are poorly understood. The aim of this study is to describe intraoperative perfusion patterns of the sigmoid colon during open AAA repair and their potential impact on postoperative outcome.

NCT ID: NCT03425305 Active, not recruiting - Heart Failure Clinical Trials

Serum Uric Acid Levels and Onset of Cardiovascular Diseases: a CALIBER Study

Start date: January 1998
Phase: N/A
Study type: Observational

Serum uric acid level is a commonly measured biomarker. The association between serum uric acid level and the risk of developing cardiovascular diseases has been observed in some studies, while others showed controversial results. Estimation of this association may help to predict cardiovascular outcomes and may guide new treatment strategies. The hypothesis is that increased serum uric acid level is associated with a range of cardiovascular diseases.

NCT ID: NCT03320408 Recruiting - Clinical trials for Abdominal Aortic Aneurysm

Predicting Aneurysm Growth and Rupture With Longitudinal Biomarkers

PARIS
Start date: October 4, 2017
Phase: N/A
Study type: Observational [Patient Registry]

First aim: PARIS study The main aim of the current study is to determine the association between abdominal aortic aneurysm (AAA) progression and the evolution of proteases and cytokines levels.To achieve this aim, we will prospectively collect blood, aortic tissue, patient data, and imaging data. Aortic tissue will only be obtained when patients undergo conventional open repair. The other biomaterials will be collected during regular patient follow-up visits, with a maximum frequency of once per year. Second aim: Pearl AAA biobank For future research purposes, a new biobanking infrastructure will be created to collect and store additional blood and urine samples in a biobank. This biobank will be embedded within the infrastructure of the 'Parelsnoer Institute' (PSI) and will be called Pearl AAA. The Pearl AAA will be established in the extension of the PARIS study

NCT ID: NCT03296280 Enrolling by invitation - Heart Failure Clinical Trials

Evaluation of Implementation of a National Point-of-Care Ultrasound Training Program

Start date: October 3, 2016
Phase:
Study type: Observational

This VA QUERI Partnered Evaluation Initiative will evaluate the impact of an immersive Point-of-care Ultrasound (POCUS) Training Course on provider skill acquisition and retention; the frequency of POCUS use by trained providers; and the barriers/facilitators to POCUS in the VHA. Data sources include pre- and post-course assessment tools, medical coding data, and course evaluations. Providers that participate in the POCUS Training Course will be compared to control providers from wait-listed facilities. Additionally, participating facilities vs. wait-listed facilities for the POCUS Training Course will be compared. Findings from this project will guide ongoing efforts of the investigators' operating partners, VA Specialty Care Centers of Innovation (SCCI) and the VA Simulation Learning and Research Network (SimLEARN), to develop a national POCUS training program and facilitate implementation of POCUS use system-wide in the VA healthcare system.

NCT ID: NCT03277781 Recruiting - Clinical trials for Abdominal Aortic Aneurysm

Female Aneurysm Screening STudy

FAST
Start date: November 1, 2016
Phase: N/A
Study type: Observational

An abdominal aortic aneurysm (AAA) is a swelling of the main blood vessel (aorta) in the abdomen. If the swelling gets too large the aorta can burst and this is usually fatal. In order to prevent rupture, AAA can be surgically repaired. This is usually carried out when the size of the AAA is more than 5.5cm in diameter as below this size, the risk of rupture is lower than the risk of surgery. AAA are usually asymptomatic before rupture but can easily and safely be diagnosed by ultrasound scanning. There is currently a national screening programme for men, but not women. Women are not screened for AAA on the basis that the disease is less common in females. However, 33.6% of all deaths caused by ruptured AAA in England and Wales are in females (1109 female deaths)1. Death rates due to ruptured AAA in men have nearly halved over the last decade but the reduction in female deaths over the same time period is less than one third. Females with AAA are also 4-times more likely to rupture their aneurysm and have higher rates of complications and death after emergency surgery than men. There are groups of females such as smokers, who are at high risk of AAA. The investigators have identified risk factors that are easily identifiable from general practice databases that may be able to identify women at high risk of AAA. In this research it will be determined whether it is feasible to select women for AAA screening using these risk factors, how many women in these high-risk groups attend if they are invited for AAA screening, and screen women to determine the numbers in the different risk groups who have AAA. This will allow the assessment of whether screening women for AAA could be clinically or cost effective and who would benefit the most. The investigators will also investigate if the siblings of patients with AAAs are at higher risk of disease by inviting them for screening too.
