Table 3.
Predicted probability of survival for different follow-up durations.
| Time | Probability of Survival (S0(t)) after Recalibration | Probability of Survival (S0(t)) Reported by Cadrin-Tourigny |
|---|---|---|
| 1-year | 0.780 | 0.921 |
| 2-year | 0.671 | 0.876 |
| 3-year | 0.610 | 0.849 |
| 4-year | 0.584 | 0.837 |
| 5-year | 0.512 | 0.801 |
Taking 5-year risk as an example, P (VA at 5 years) = 1 − 0.801 0.512exp (LP) where LP = 0.488 × sex − 0.022 × age + 0.657 × history of recent cardiac syncope + 0.811 × history of NSVT + 0.170 × ln(24 h PVC count) + 0.113 × sum of anterior and inferior leads with T-wave inversion − 0.025 × RVEF.
