- Abstract
This study is a prospective evaluation of the effectiveness of cardiac rehabilitation (CR) in terms of clinical outcomes for small abdominal aortic aneurysms (AAA) that were previously reported in a retrospective cohort study. We conducted a prospective non-randomized trial on patients with small AAA (N = 40; mean age 75.0 ± 6.6 years). Patients were enrolled into one of two groups, rehabilitation (CR) or non-rehabilitation (non-CR) group. Only CR group participated in a supervised-CR program including bicycle ergometer for 150 days. The AAA expansion rate and the risk of AAA repair were compared between two groups. We also researched the relationship between AAA expansion rate and body composition, blood IL-6 and TGFβ1 levels. The CR (N = 15) and non-CR groups (N = 25) were comparable in terms their baseline data. The CR group had a significantly smaller change in the maximal AAA size (− 1.3 ± 2.4 mm/years) compared to the non-CR group (2.0 ± 3.6 mm/years) (p < 0.01). The IL-6, and TGFβ1 levels were unrelated to the changes in AAA size. There was mild positive correlation between the change in systolic blood pressure from rest to exercise and the AAA expansion rate (p = 0.06). The risk of AAA repair after 12 months was lower in the CR group compared to the non-CR group (0% vs. 28%, respectively). CR in patients with small AAA significantly suppressed AAA expansion and resulted in a lowered risk of AAA repair.
