Evaluation of the Six Minute Walk Test and Other Instruments in Heart Failure

If patients meet the criteria of the study, their data will be collected and will be interviewed to fill the Minnesota Living with Heart Failure Questionnaire (MLHFQ). They then will be taken to the hallway to perform the six minute walk test monitored with a heart rate monitor (Polar RS800 CX). After the test there will be a break of 20 to 30 minutes before repeating the walk test. During rest time, the patient will answer the general health survey questionnaire: Medical Outcome Study 36-item Short-Form Health Survey (SF-36).
