| Outcome | Score equation | Area under the curve (AUC)* | |
|---|---|---|---|
| Unadjusted | Adjusted† | ||
| 5-year-all-cause mortality | HRR+13.0×METs−12.6×STΔ (0/1) | 0.77 | 0.86 |
| 5-year-CV mortality | HRR+7.3×METs−10.5×STΔ (0/1) | 0.81 | 0.88 |
| 5-year-CV mortality or MI | HRR+9.4×METs−15.7×STΔ (0/1) | 0.79 | 0.83 |
| 12-year-all-cause mortality | HRR+14.5×METs−14.2×STΔ (0/1) | 0.77 | 0.83 |
| 12-year-CV mortality | HRR+13.8×METs−17.1×STΔ (0/1) | 0.78 | 0.82 |
*C-statistic (AUC) based on a logistic model.
†Arm Exercise Score adjusted for significant demographic and clinical variables indicated in table 4.
AUC, area under the curve; CV, cardiovascular; HRR, heart rate recovery at 1 min postexercise; METs, resting metabolic equivalents; MI, myocardial infarction; ST, ST segment depression.
