The association of clinical indication for exercise stress testing with all-cause mortality: the FIT Project.

Introduction: We hypothesized that the indication for stress testing provided by the referring physician would be an independent predictor of all-cause mortality.

Material And Methods: We studied 48,914 patients from The Henry Ford Exercise Testing Project (The FIT Project) without known congestive heart failure who were referred for a clinical treadmill stress test and followed for 11 ±4.7 years.
