Aspirin use may significantly delay progression of Abdominal Aortic Aneurysm with favorable safety profile.
The preclinical research indicates that aspirin may play a role in slowing the progression of abdominal aortic aneurysms (AAAs) and averting their rupture. However, human studies are scarce to demonstrate the clinical advantages of aspirin in treating AAA.
In a recent retrospective study of a clinical cohort of 3435 patients with objectively measured changes in aortic aneurysm progression, aspirin usage slowed the progression of abdominal aortic aneurysm (AAA) with a favorable safety profile.
This original Investigation on Cardiology was published in JAMA Network Open.
This retrospective study included adult patients with at least two vascular ultrasounds available at the Cleveland Clinic. Patients with a history of aneurysm repair, dissection, or rupture were excluded. All patients were followed for ten years, and clinical outcomes were analyzed from May 2022 to July 2023. The primary outcomes were the time-to-first occurrence of all-cause mortality, major bleeding, or a composite of dissection, rupture, and repair. Multivariable-adjusted Cox proportional-hazard regression and Fine and Gray proportional subhazard regression were used.
