Older athletes who look healthy can still have hidden clogged arteries that suddenly cause their heart to stop, which is why we need better ways to find these problems before it's too late.
Scientific Claim
Asymptomatic atherosclerotic cardiovascular disease is the leading cause of sudden cardiac death in athletes over 35 years of age, due to undetected coronary atherosclerosis that can lead to plaque rupture and acute coronary thrombosis, highlighting the need for improved detection in this population.
Original Statement
“Asymptomatic atherosclerotic cardiovascular disease (ASCVD) is the leading cause of sudden cardiac death (SCD) in athletes over 35 years of age. Despite their high physical fitness, athletes in this age group remain vulnerable to undetected coronary atherosclerosis, which predisposes them to plaque rupture and acute coronary thrombosis.”

Assessment Explanation
The abstract presents this as a descriptive summary of existing literature, but uses language like 'predisposes them to' which implies causation. As a narrative review with no original data, it cannot establish causal links — only associations reported in prior studies.
More Accurate Statement
“Asymptomatic atherosclerotic cardiovascular disease is commonly associated with sudden cardiac death in athletes over 35 years of age, with prior studies suggesting that undetected coronary atherosclerosis may lead to plaque rupture and acute coronary thrombosis.”
Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Systematic Review & Meta-AnalysisLevel 1aThe relative contribution of ASCVD versus other causes to SCD in athletes over 35 across diverse populations, with pooled incidence rates and confidence intervals.
The relative contribution of ASCVD versus other causes to SCD in athletes over 35 across diverse populations, with pooled incidence rates and confidence intervals.
What This Would Prove
The relative contribution of ASCVD versus other causes to SCD in athletes over 35 across diverse populations, with pooled incidence rates and confidence intervals.
Ideal Study Design
A systematic review and meta-analysis of prospective cohort studies including at least 10,000 athletes aged 35–65 with documented SCD events, using standardized autopsy or imaging criteria to classify cause of death, stratified by sport type, training intensity, and cardiovascular risk factors.
Limitation: Cannot prove causation or determine if screening interventions reduce SCD rates.
Prospective Cohort StudyLevel 2bThe incidence and progression of asymptomatic ASCVD in athletes over 35 over time, and its temporal association with subsequent SCD events.
The incidence and progression of asymptomatic ASCVD in athletes over 35 over time, and its temporal association with subsequent SCD events.
What This Would Prove
The incidence and progression of asymptomatic ASCVD in athletes over 35 over time, and its temporal association with subsequent SCD events.
Ideal Study Design
A prospective cohort of 5,000 asymptomatic athletes aged 35–65 undergoing annual CCTA and lipid profiling for 10 years, with adjudicated SCD events as primary endpoint, controlling for smoking, hypertension, and family history.
Limitation: Cannot rule out unmeasured confounders or prove that screening prevents death.
Case-Control StudyLevel 3bWhether the presence and severity of asymptomatic ASCVD is more common in athletes who died of SCD compared to matched living athletes.
Whether the presence and severity of asymptomatic ASCVD is more common in athletes who died of SCD compared to matched living athletes.
What This Would Prove
Whether the presence and severity of asymptomatic ASCVD is more common in athletes who died of SCD compared to matched living athletes.
Ideal Study Design
A case-control study comparing 200 athletes who died of SCD over age 35 with 400 living matched controls, using CCTA to quantify coronary plaque burden, with blinded adjudication of cause of death.
Limitation: Retrospective design limits ability to establish temporal sequence or causality.

Atherosclerosis and Sudden Cardiac Death in Athletes.
This study says that older athletes who look healthy can still have hidden artery disease that causes sudden heart death, and we need better tests to find it before it’s too late — which is exactly what the claim says.
