Acute Aortic Syndrome

The goal of this study is to evaluate the safety of integrating the Aortic Dissection Detection Risk Score (ADD-RS) and D-dimer testing for ruling out acute aortic syndrome (AAS) in the emergency department (ED). The main question it aims to answer: Can the combination of the ADD-RS \<2, and D dimer \<500ng/mL rule-out AAS in ED patients without CTA? The researchers will recruit patients suspected with AAS in the ED, and the patients will receive a ADD-RS score, a D-dimer testing after signing a written consent.

The goal of this retrospective observational study is to evaluate the diagnostic performance of the AORTAs score integrated with environmental exposure data (AORTAs-E) for the identification of Acute Aortic Syndrome (AAS) during initial maangement in the emergency departement. The main question it aims to answer is: Can the integration of real-time meteorological and atmospheric pollution data improve the early identification of AAS in patients presenting in the emergency department for chest, abdominal, or back pain? Researchers will analyze medical records and environmental data for 580 adult patients (290 cases with confirmed AAS and 290 controls) managed at the University Hospital of Besançon between 2014 and 2026. Environmental exposure, including temperature and pollutant concentrations, will be calculated based on each patient's residential address to determine if adding these factors to clinical data increases diagnostic accuracy.

Acute aortic syndrome (AAS) is a life-threatening condition. Inflammation plays a key role in the pathogenesis, development and progression of AAS, and is associated with significant mortality and morbidity. Understanding the inflammatory responses and inflammation resolutions is essential for an appropriate management of AAS. Twenty Chinese cardiovascular centers have collaborated to create a multicenter observational registry (named Chinese registry of Additive Anti-inflammatory Action for Aortopathy \& Arteriopathy \[5A\]), with consecutive enrollment of adult patients who underwent surgery for AAS that was started on Jan 1, 2016 and will be ended on December 31, 2040. Specially, the impact of inflammation and anti-inflammatory strategies on the early and late adverse events are investigated. Primary outcomes are severe systemic inflammatory response syndrome (SIRS), multiple organ dysfunction syndrome (MODS), Sequential Organ Failure Assessment (SOFA) scores at 7 days following this current surgery. Secondary outcomes are SISR, 30-day mortality, operative mortality, hospital mortality, new-onset stroke, acute kidney injury, surgical site infection, reoperation for bleeding, blood transfusion and length of stay in the intensive care unit.

Acute Aortic Syndrome (AAS)/Aortic Aneurysm is a common feature of aortic wall events, including aortic dissection, intramural hematoma, aortic ulceration and aortic trauma, and occurs in up to 35 cases per 100,000 cases per year between the ages of 65 and 75 years. Increased levels of the inflammatory biomarker high-sensitivity C-reactive protein predict cardiovascular events. Since statins lower levels of high-sensitivity C-reactive protein as well as cholesterol, the authors hypothesized that people with acute aortic syndrome but without hyperlipidemia might benefit from statin treatment.

Systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS) are the major causes of death in patients with acute aortic syndrome (AAS). Therefore, the prevention of SIRS and MODS is of great clinical value, and immunomodulatory therapy with thymosin alpha 1 may be beneficial. This study was designed to test the hypothesis that the administration of thymosin alpha 1 during the acute phase of AAS will result in a reduced incidence of SIRS and MODS.

The objective of this study to evaluate the safety and effectiveness of the Castor single branch stent graft for endovascular repair of acute aortic syndrome patients without an inadequate proximal landing zone (\<15mm)
