Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Operative mortality

    Operative mortality was defined as any death, regardless of cause, occurring whether within 30 days after surgery in or out of the hospital or after 30 days during the same hospitalization subsequent to the operation.

    30 days after treatment

  • Severe systemic inflammatory response syndrome (SIRS)

    SIRS was defined as the presence of at least 2 of the 4 age-specific criteria: temperature, heart rate, respiratory rate, and leukocyte count, one of which must be abnormal temperature or leukocyte count. severe SIRS was defined as meeting all 4 aforementioned criteria, measured immediately following surgery through postoperative day 7.

    7 days after treatment

Interventions

Data were collected by a designed form. Statistic software was used to analyze clinical data.
