Abstract
BACKGROUND AND OBJECTIVES:
Previous estimates of sudden cardiac death in children and young adults vary significantly, and population-based studies in the United States are lacking. We sought to estimate the incidence, causes, and mortality trends of sudden cardiac death in children and young adults (1–34 years).
METHODS:
Demographic and mortality data based on death certificates for US residents (1–34 years) were obtained (1999–2015). Cases of sudden death and sudden cardiac death were retrieved by using the International Classification of Diseases, 10th Revision codes.
RESULTS:
A total of 1 452 808 subjects aged 1 to 34 years died in the United States, of which 31 492 (2%) were due to sudden cardiac death. The estimated incidence of sudden cardiac death is 1.32 per 100 000 individuals and increased with age from 0.49 (1–10 years) to 2.76 (26–34 years). During the study period, incidence of sudden cardiac death declined from 1.48 to 1.13 per 100 000 (P < .001). Mortality reduction was observed across all racial and ethnic groups with a varying magnitude and was highest in children aged 11 to 18 years. Significant disparities were found, with non-Hispanic African American individuals and individuals aged 26 to 34 years having the highest mortality rates. The majority of young children (1–10 years) died of congenital heart disease (n = 1525, 46%), whereas young adults died most commonly from ischemic heart disease (n = 5075, 29%).
CONCLUSIONS:
Out-of-hospital sudden cardiac death rates declined 24% from 1999 to 2015. Disparities in mortality exist across age groups and racial and ethnic groups, with non-Hispanic African American individuals having the highest mortality rates.
