When to Use

When to Use

Prior to elevated-risk non-cardiac surgery as part of the standard pre-operative cardiovascular evaluation
To objectively quantify a patient's subjective functional capacity rather than relying on unstructured physician estimation ("Can you climb a flight of stairs?")
In heart failure clinics to monitor trajectory of functional decline without formal CPET (Cardiopulmonary Exercise Testing)
