We often use coronary CTA to rule out coronary disease in low risk chest pain, but I can't say I would recommend it as a routine test due to the radiation and the dye load. We know that the fatty streak begins in childhood and it must be true that there is a lot of clinically undetected coronary disease. When it comes to sudden cardiac death for a young man, I'd also be concerned about electrical abnormalities such as the Brugada syndrome / channelopathies / accessory pathway syndromes. Drug use is another important factor in general, not that I would think it to be relevant here.

May the family of the deceased find peace.
