Cardiovascular Rehabilitation and Reeducation (CVRR) in Patients With Cardiac Pathologies and the 6-minute Stepper Test

Use and Validation of the 6-minute Stepper Test in in Patients With Cardiac Pathologies Needing Rehabilitation and Reeducation (CVRR)

The objective is to study the validity of the 6-minute stepper test (ST6) in order to determine tolerance to effort in cardiovascular patients

The 6-minute stepper test (ST6) is an test used and validated in patients with respiratory disorders (chronic obstructive pulmonary disease) in order to evaluate their tolerance to exercise. It is well tolerated and reproducible in these patients, with the advantage that it can be performed without spatial constraints.

However, this test is not yet used in cardiology. This study proposes to validate the ST6, to evaluate the exercise tolerance of patients suffering from cardiovascular pathologies.
