Key result
In patients after open-heart valve surgery, 6-minute walk test distance independently predicted cardiovascular death (adjusted HR 0.88; 95% CI 0.75-0.98; P=0.028).

Does the 6-minute walk test distance predict cardiovascular death and cardiac hospitalization in patients undergoing cardiovascular rehabilitation after open-heart valve surgery?
Hazard Ratio: 0.88 (95% CI 0.75–0.98)
p-value: p=0.028
The 6-minute walk test distance is an independent prognostic marker for cardiovascular death and cardiac hospitalization in patients undergoing in-hospital rehabilitation after open-heart valve surgery.
Vitale et al. (2018) conducted a cohort in open-heart valve surgery (n=101). 6-minute walk test (6MWT) distance was evaluated on cardiovascular death (adjusted HR 0.88, 95% CI 0.75-0.98, p=0.028). In patients after open-heart valve surgery, 6-minute walk test distance independently predicted cardiovascular death (adjusted HR 0.88; 95% CI 0.75-0.98; P=0.028).
