Researchers have developed the FIT Treadmill Score, which can translate basic treadmill performance measures into a fitness-related mortality risk score.
A retrospective cohort study included 58,020 adults aged 18 to 96 years free from known CVD who were referred for an exercise stress test between 1991 and May 2009 (median age, 53 years; 49% women). Researchers collected demographic, clinical, exercise and mortality data to identify exercise test variables most predictive of survival. The beta coefficients of the model with the highest survival discrimination were used to construct the FIT Treadmill Score.
