Evaluation of the Six Minute Walk Test and Other Instruments in Heart Failure
The purpose of this study is to assess functional capacity, quality of life and functioning of the autonomic nervous system in patients with heart failure. The study hypothesis is that subjects who walk less distance, have lower quality of life and reduced heart rate variability during the six minute walk test.

|Study Design:||Observational Model: Case-Only
Time Perspective: Cross-Sectional
|Official Title:||Evaluation of the Six Minute Walk Test, Heart Rate Variability and Quality of Life in Heart Failure|
- Maximum distance walked [ Time Frame: During six minute walk test ] [ Designated as safety issue: No ]The six minute walk test will be performed twice by each patient, at the same day. The collection period will extend until the sample is complete. This is an observational study because there is no follow up and reassessment of patients.

|Estimated Primary Completion Date:||March 2013 (Final data collection date for primary outcome measure)|
Heart failure group
All heart failure group participants will perform two walk tests at the same day, with a heart rate monitor, and answer questionnaires about their perception of quality of life. Tests will be conducted on a single day, without follow up of patients. The six minute walk test will be performed according the American Thoracic Society Statement (2002).
Other: Six minute walk test
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).
Heart failure and its treatment result in symptoms such as pulmonary or systemic congestion causing impairment to the effort, psychological and social commitment, and impact on quality of life.
