Precision Medicine for Cardiomyopathy (PRIMaCY) Score
Predicts sudden cardiac death (SCD) risk in pediatric patients with hypertrophic cardiomyopathy (HCM).
Use in patients <18 years old at diagnosis with primary HCM. Treatment decisions should be made with patient-physician shared decision-making.
Advice
- The tool does not provide treatment recommendations based on PRIMaCY score alone.
- The PRIMaCY score should be used in conjunction with the physician’s clinical judgment to help guide a shared decision-making discussion between physician and patient regarding risk of SCD, risk and benefit of ICD, and patient preferences.

Graded SCD risk bar.
