When patients participate in cardiopulmonary stress testing with the 6-minute walk test, a normal value is considered to be 1500 feet. Anything less than that value may indicate cardiac dysfunction. Those patients who cannot walk more than 600 feet have severe cardiac dysfunction and are more likely to have worse short- and long-term prognoses.

In addition to distance, the 6-minute walk test also measures:

  • Dyspnea index on a Borg scale from 0 to 10

  • Heart rate response to exercise

  • Oxygen saturation
