Abstract

Background: Hypertrophic cardiomyopathy (HCM)-related mortality has been decreasing within the United States; however, persistent disparities in demographic subsets may exist. In this study, we assessed nationwide trends in mortality related to HCM among people ≥15 years of age in the United States from 1999 to 2019.
Methods: Trends in mortality related to HCM were assessed through a cross-sectional analysis of the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiological Research database. Age-adjusted mortality rates per 1 000 000 people and associated annual percent changes with 95% CIs were determined. Joinpoint regression was used to assess the trends in the overall, demographic (sex, race and ethnicity, age), and regional groups.
Results: Between 1999 and 2019, 39 200 HCM-related deaths occurred. In the overall population, age-adjusted mortality rate decreased from 11.2 in 1999 to 5.4 in 2019. Higher mortality rates were observed for males, Black patients, and patients ≥75 years of age. Large metropolitan counties experienced pronounced declines in age-adjusted mortality rate over the study period. In addition, California had the highest overall age-adjusted mortality rate.
Conclusions: Over the past 2 decades, HCM-related mortality has decreased overall in the United States. However, demographic and geographic disparities in HCM-related mortality have persisted over time and require further investigation.
