Key result
Slow gait speed in cardiac surgery patients is linked to ~132% higher in-hospital mortality.
Why the study?
Frailty is associated with poorer outcomes in cardiac surgery, but heterogeneity in frailty assessment tools complicates understanding its true impact.
Is slow gait speed associated with worse in-hospital mortality and postoperative outcomes in cardiac surgery patients?
Meta-Analysis (n=36,697)
Is slow gait speed associated with worse in-hospital mortality and postoperative outcomes in cardiac surgery patients?
Relative Risk: 2.32 (95% CI 1.87–2.87)
Slow gait speed is a strong predictor of in-hospital mortality and perioperative complications in cardiac surgery patients, serving as a simple and reliable marker for frailty.
No takes yet. Share an insight, caveat, or question.
Slow gait speed doubles in-hospital mortality risk after cardiac surgery; extends evidence supporting routine preoperative frailty screening.
Chang et al. (2021) conducted a meta-analysis in Cardiac surgery (n=36,697). Slow gait speed vs. Normal gait speed was evaluated on in-hospital mortality (RR 2.32, 95% CI 1.87-2.87). Slow gait speed in cardiac surgery patients was associated with a significantly increased risk of in-hospital mortality (RR 2.32; 95% CI 1.87-2.87).
