Implication
Sudden death risk in HCM extends beyond youth; challenges prior assumptions from selected cohorts but remains hypothesis-generating.
Key Points
- Characterize the modes, age distribution, and epidemiological patterns of cardiovascular death in a regionally based, unselected cohort of patients with hypertrophic cardiomyopathy.
- Prospective cohort study tracking a regionally based, predominantly unselected population of patients with hypertrophic cardiomyopathy (HCM).
- HCM-related cardiovascular mortality occurred via sudden cardiac death, progressive heart failure, or stroke across distinct phases of life.
- Sudden death occurred predominantly in adolescents and young adults but also extended into older age groups.
- Traditional disease models based on selected referral populations introduced significant reporting skew, demonstrating the need for updated risk stratification and sudden death prevention protocols.

Outcome
HCM-related cardiovascular death (sudden death, heart failure, or stroke)hard clinical
The study demonstrates that sudden death in HCM is not confined to young patients but extends into later life, challenging previous epidemiological assumptions derived from highly selected populations.
