NDLVC-5y Score

Calculation Formula

5-year risk of MAE = 1 − (0.99600731958437)^exp(PI)

PI is the sum of each parameter multiplied by its coefficient:

• 0.8605 × Male sex
• 1.6967 × LVEF <45%
• 1.1288 × Nonsustained ventricular tachycardia
• 0.6929 × Septal LGE
• 0.2275 × Ring-like pattern LGE
• 1.5336 × Pathogenic/likely pathogenic variants in "high-risk" genes^a
• 2.7535 × Myocardial inflammation

Each variable equals 1 if present, otherwise 0. The constant 0.99600731958437 represents the baseline survival.
