Any person at an increased risk for arrhythmia, cardiovascular collapse, or respiratory distress with walking at a usual pace may be at an increased risk for an adverse event during the 6 MWT. The only absolute contraindication is patient refusal to do the test for any reason. Rather, the information it provides is complementary to it. The 6 MWT should not be considered to be a replacement for cardiopulmonary exercise stress testing. Some authors have compared it to a “biomarker” that can be used as a surrogate endpoint.Ĭommon conditions where 6 MWT may provide useful information on response to therapy include:Ĭardiac rehabilitation/coronary artery disease (CAD)Ĭonditions where 6 MWT has been shown to be a significant predictor of morbidity and mortality includeĬonditions where 6 MWT has been helpful for one time measurement of functional status include: It is also used to measure functional status and evaluate prognosis in various medical and surgical conditions. The main indication for performing a 6 MWT in a patient with cardiopulmonary disease is to measure response to medical or surgical intervention.
