Key result
In a young Portuguese population, the annual incidence of sudden death was 2.4 per 100,000 person-years, with cardiac causes accounting for 70.4% of cases, predominantly atherosclerotic coronary artery disease.
Why the study?
The annual incidence and leading causes of sudden non-cardiac and cardiac death in children and young adults in Portugal were not well described.
Population
159 sudden death victims aged 1-40 years in central Portugal, Azores, and Madeira
Design
Retrospective cross-sectional postmortem study

Low SD incidence in young Portuguese; supports CAD prevention focus and molecular autopsy; leaves open prospective validation before practice change.

Atherosclerotic coronary artery disease is the leading cause of sudden cardiac death in young Portuguese individuals, highlighting the need for early primary prevention and molecular autopsy for cases with uncertain findings.
Carrington et al. (2023) conducted a cross-sectional in Sudden death (n=159). Postmortem examination was evaluated on Annual incidence of sudden death per 100,000 person-years (95% CI 1.5-3.6). In a young Portuguese population, the annual incidence of sudden death was 2.4 per 100,000 person-years, with cardiac causes accounting for 70.4% of cases, predominantly atherosclerotic coronary artery disease.
