Associations Between WT Performance and Heart Failure–Related Impairments Assessed Using 3 KCCQ Scales

WT MeasureKCCQ Scale
Physical LimitationClinical SummaryOverall Summary
6MWT distance walked0.380.410.31§
60ftWT completion time−0.49−0.44−0.40

KCCQ = Kansas City Cardiomyopathy Questionnaire; 6MWT = 6-min walk test; 60ftWT = 60-foot walk test; WT = walk test.

  • Data represent standardized regression coefficients adjusted for covariates.

  • Higher KCCQ scores indicate lesser impairment. Therefore, results indicate that lesser self-reported impairment is associated with longer 6MWT distance walked and shorter time to complete the 60ftWT.
