Key result
Prehabilitation exercise therapy before elective abdominal aortic aneurysm repair has uncertain effects on 30-day mortality (RR 1.33; 95% CI 0.31-5.77) but may reduce cardiac and renal complications.
Why the study?
Perioperative and postoperative morbidity is common after elective AAA repair, and existing studies evaluating prehabilitation exercise interventions have shown conflicting results.
Does prehabilitation exercise therapy reduce perioperative and postoperative morbidity and mortality in patients waiting for elective abdominal aortic aneurysm repair?
Population
232 participants with clinically diagnosed AAA suitable for elective intervention across 4 RCTs
Comparison
Prehabilitation exercise therapy vs usual care (no exercise)
Design
Systematic review and meta-analysis of RCTs

May merit prehabilitation consideration before AAA repair to reduce complications; leaves mortality effect uncertain, warranting higher-certainty trials.
Systematic Review (n=232)
Does prehabilitation exercise therapy reduce perioperative and postoperative morbidity and mortality in patients waiting for elective abdominal aortic aneurysm repair?
Relative Risk: 1.33 (95% CI 0.31–5.77)
Prehabilitation exercise therapy before elective AAA repair may slightly reduce cardiac and renal complications, but evidence is of low certainty and its effect on mortality remains uncertain.
Fenton et al. (2020) conducted a systematic review in Abdominal aortic aneurysm (AAA) (n=232). Prehabilitation exercise therapy vs. Usual care (no exercise) was evaluated on 30-day mortality post-AAA repair (RR 1.33, 95% CI 0.31 to 5.77). Prehabilitation exercise therapy before elective abdominal aortic aneurysm repair has uncertain effects on 30-day mortality (RR 1.33; 95% CI 0.31-5.77) but may reduce cardiac and renal complications.
