The clogs in athletes' arteries are silent — they don’t cause pain or symptoms, and only show up on special scans.
Scientific Claim
Coronary artery plaque in high-volume endurance athletes is predominantly subclinical, detectable only via imaging modalities such as coronary CT angiography, and is not associated with symptomatic ischemia or angina.
Original Statement
“The plaque in the athletes arteries, they were found because they were looking for it using a CT scanner. It wasn't causing obvious symptoms or problems.”

Coronary Atherosclerosis in Masters Athletes: Mechanisms and Implications for Cardiovascular Disease Risk
Even though these super-fit athletes have plaque in their heart arteries, they usually don’t feel chest pain or have heart attacks because the plaque is stable and doesn’t cause symptoms — only special scans can find it.
Technical explanation
This study used CT angiography and cardiac MRI to detect subclinical plaque and myocardial fibrosis in athletes who had no symptoms of heart disease. It confirmed that the plaque was present but not causing functional impairment, supporting the video’s assertion that the findings are subclinical and asymptomatic.

Lifelong endurance exercise and its relation with coronary atherosclerosis
The study found that elite athletes have more plaque in their heart arteries, but it didn’t check if they had chest pain or heart problems—so we can’t say if the plaque is harmless or dangerous based on this study.
