Functional Capacity Assessment
Metabolic Equivalents of Tasks
Duke Activity Status Index (DASI)
METs ≥ 4
In most cases, functional, asymptomatic patients may proceed with planned noncardiac without further cardiovascular testing.
METs < 4
Patients with poor functional capacity are at increased risk of cardiac events post surgery.
