Key result
The 6-minute walk test correlated with the SF-36 physical functioning subscale at baseline (rs=0.44) and 3 months postoperatively (rs=0.54), supporting its use to assess cardiac surgical recovery.

May support 6MWT for recovery monitoring after cardiac surgery; leaves open validation in prospective trials.
Observational (n=125)
Effect estimate: rs = 0.44 at baseline, rs = 0.54 at 3 months
The 6-minute walk test is a valid and responsive tool for evaluating physical functioning recovery in patients after cardiac surgery.
Chen et al. (2018) conducted an observational in Cardiac surgery (n=125). 6-minute walk test (6MWT) was evaluated on Correlation of 6-minute walk distance with the physical functioning subscale of the SF-36 (rs = 0.44 at baseline, rs = 0.54 at 3 months). The 6-minute walk test correlated with the SF-36 physical functioning subscale at baseline (rs=0.44) and 3 months postoperatively (rs=0.54), supporting its use to assess cardiac surgical recovery.
