Calculation of cumulative risk score
| Risk score | Variable |
|---|---|
| *The contribution of the continuous variable SDANN to the cumulative risk score is the product of SDANN (ms) and the individual risk score ( –0.03 at 30 days, –0.02 at 12 months). | |
| 30 days (cut off = 3.75) | |
| +3.44 | Scored for troponin T >0.1 μg/l on admission or at 12 hours |
| +2.25 | Scored for ≥1 episode ST elevation on Holter |
| +2.69 | Scored for ≥1 episode of pain >12 hours after admission |
| –0.03 | SDANN* |
| 12 months (cut off = 2.5) | |
| +1.89 | Scored for troponin T >0.1 μg/l on admission or at 12 hours |
| +1.69 | Scored for T wave inversion present on admission ECG |
| +1.44 | Scored for ≥1 episode ST elevation on Holter |
| +1.17 | Scored for ≥1 episode ST depression on Holter |
| –0.02 | SDANN* |
