The overall prevalence has increased significantly in the general population, which may be due in part to advances in diagnostic techniques, such as improved imaging techniques. Aortic dissection (AD) can cause sudden cardiac death (SCD). Approximately 95% of thoracic AAS are clinically "silent" until a life-threatening complication arises in an unpredictable manner and presents as sudden cardiac death. The peak incidence of death caused by aortic dissection occurs within 48 hours, therefore, timely diagnosis is essential and saves lives. We have traditionally associated as risk factors in patients with ASA long-term arterial hypertension, present in 66-75% of cases, smoking, dyslipidemia or atherosclerotic disease. Likewise, any condition that alters the structure of the aorta such as: collagen diseases, aneurysms, bicuspid aorta, and manipulation of the thoracic aorta (cardiac surgery, 18%, or percutaneous intervention that can injure the intima) is involved in ASA. In addition to the well-known hereditary syndromes that affect collagen (Marfan, Elher-Danlos ...) there is a clear familial aggregation: 13-19% of patients without identifiable syndrome have first-degree relatives with thoracic aortic aneurysms or ICD, something that has been called "thoracic aortic dissection and familial aneurysm syndrome." Notable achievements have been made in the discovery of genetic mutations associated with SAA and key regulatory molecules involved, including the extracellular matrix (ECM), cytoskeletal proteins, and the TGF-β signaling pathway. Identification of the causative gene is advantageous for both patients and their families, especially those who do not show symptoms. The specific underlying genotype could benefit the process of diagnosis, surveillance and surgery, with the aim of reducing morbidity and mortality
Acute Aortic Syndrome (AAS) is a common feature of acute 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. Ulinastatin has antiinflammatory activity and suppresses the infiltration of neutrophils and the release of elastase and chemical mediators from neutrophils. Recent studies have shown that ulinastatin may be cytoprotective against ischemia-reperfusion injury in the liver, kidney, heart, and lung. The authors aim to examine the association between decreased release of inflammatory response to urinary trypsin inhibitor treatment and decreased myocardial and lung injury after acute aortic syndrome surgery.

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.
Observational, prospective, multicentre, international, non-profit, investigator-driven, diagnostic accuracy study performed in several international EDs. The aim of the study will be to evaluate the performance of an integrated algorithm based on aortic dissection risk score, focus cardiac ultrasound and D-dimer to rule-in and -out acute aortic syndromes. The final diagnosis will be established after review all available hospital clinical data and one month follow-up.
The purpose of this study is to determine whether Sodium Fluoride imaging (using Positron Emission Tomography-Computed Tomography - PET-CT) is able to predict disease progression in acute aortic syndrome.
Acute Aortic Syndrome (AAS) is a potentially life-threatening cause of sudden, severe chest pain. There are several possible underlying causes, which cannot be distinguished from one another at the bedside. Current practice is to image this with two CT scans of the chest, one before injection of a contrast dye into the blood stream and then one after. With the advancement of CT scanner technology, improvements in software interpretation and screen resolution, the investigators hypothesise that performing the contrast scan on its own is diagnostically equivalent to both the pre- and contrast scans
The study examined the clinical characteristics and conditions of care for patients with acute aortic syndrome (AAS) that will identify patients at risk for increased morbidity and mortality and provide a basis for the eventual achievement of specific studies on the optimal therapeutic management according to different risk profiles. The aim of the Observatory is to provide a photograph "size" of practices in France at present, both in the larger centers than in smaller and optimize diagnostic and therapeutic currently available by the activation pathways of rational management.
