New tests like heart scans for calcium buildup and DNA tests for inherited heart defects might help doctors better guess which athletes are at highest risk of sudden death.
Scientific Claim
Emerging evidence suggests that integrating biomarkers such as coronary calcium scoring and genetic testing for congenital anomalies may improve risk stratification for sudden cardiac death in athletes.
Original Statement
“Emerging evidence supports integrating biomarkers, for instance, coronary calcium scoring and genetic testing for congenital anomalies, to enhance risk stratification.”

Assessment Explanation
The phrase 'emerging evidence supports' implies a level of validation that a narrative review cannot provide. The review summarizes findings from other studies but does not generate or validate this evidence.
More Accurate Statement
“Some emerging studies suggest that coronary calcium scoring and genetic testing for congenital anomalies may have potential to improve risk stratification for sudden cardiac death in athletes, though clinical utility remains under investigation.”
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.
Prospective Cohort StudyLevel 2bWhether adding coronary calcium scoring or genetic testing improves prediction of SCD beyond traditional risk factors in athletes over 35.
Whether adding coronary calcium scoring or genetic testing improves prediction of SCD beyond traditional risk factors in athletes over 35.
What This Would Prove
Whether adding coronary calcium scoring or genetic testing improves prediction of SCD beyond traditional risk factors in athletes over 35.
Ideal Study Design
A prospective cohort of 3,000 athletes aged 35–65 with baseline coronary calcium scoring and genetic testing for 10 key arrhythmia/coronary anomaly genes, followed for 7 years for SCD events, with C-statistic and NRI analysis comparing models.
Limitation: Cannot prove that using these tests reduces SCD — only that they improve prediction.
Case-Control StudyLevel 3bWhether athletes who died of SCD had higher coronary calcium scores or pathogenic genetic variants compared to living controls.
Whether athletes who died of SCD had higher coronary calcium scores or pathogenic genetic variants compared to living controls.
What This Would Prove
Whether athletes who died of SCD had higher coronary calcium scores or pathogenic genetic variants compared to living controls.
Ideal Study Design
A case-control study comparing 150 athletes who died of SCD over age 35 with 300 matched living controls, analyzing archived coronary calcium scores and DNA for known pathogenic variants in genes like LDLR, MYH7, and SCN5A.
Limitation: Retrospective design limits causal inference and generalizability.

Atherosclerosis and Sudden Cardiac Death in Athletes.
The study says using tests like heart scans and genetic checks can help find athletes at risk of sudden heart death better than current methods, which matches exactly what the claim says.
