Acute cardiac care & resuscitation
Sudden Cardiac Arrest During Sports Activity in Older Adults
Authors' conclusion
Among free-living community residents age ≥65 years, SrSCA is uncommon, predominantly occurs in men, and is associated with lower disease burden than non-SrSCA.
Study context
- Population
- Out-of-hospital SCA in subjects ≥65 years, Portland, Oregon (2002–2017) and Ventura County, California (2015–2021); catchment ∼1.85 millionSudden cardiac arrests (SCAs) age ≥65 years
- Participants
- 4,078 participants
- Exposure
- Sports-related SCA vs non-sports-related SCA
- Sports-related sudden cardiac arrest (SrSCA)n = 77
- Outcome
- Prevalence and characteristics of SrSCA
Methodological detailsprospective ascertainment, Portland, Oregon and Ventura County, California
- Prospective ascertainment
