Study Links Heart Scar Tissue to Dangerous Rhythms in Older Male Athletes
TL;DR
Understanding the link between heart scar tissue and dangerous rhythms in athletes over 50 can give competitors an edge in monitoring and preventing sudden cardiac risks.
The VENTOUX study utilized CMR imaging and ECG recorders to associate myocardial fibrosis with ventricular tachycardia in endurance athletes, highlighting a method for early detection.
This research advances cardiac health understanding, offering pathways to safer sports participation for aging athletes and reducing sudden cardiac death risks globally.
A study named after Tour de France's Mont Ventoux reveals heart scar tissue in athletes may lead to dangerous rhythms, blending sports and science.

Scar tissue in the heart has been associated with abnormal heart rhythms among healthy, long-time male endurance athletes aged 50 or older, potentially elevating their risk of sudden cardiac death, according to a study published in Circulation: Cardiovascular Imaging, an American Heart Association journal. The study, named VENTOUX after a challenging segment of the Tour de France, involved 106 male cyclists and triathletes who trained at least 10 hours weekly for over 15 years, showing no prior symptoms of heart disease.
Utilizing cardiovascular magnetic resonance imaging and implanted ECG recorders, researchers discovered that nearly half of the participants exhibited signs of scarring on the left ventricle, with about 3% experiencing sustained, dangerous heart rhythms. These findings underscore the potential risks of myocardial fibrosis in athletes, suggesting a need for increased awareness and preventive strategies, including CPR training and the use of automated external defibrillators.
The study's implications are significant for the sports and medical communities, emphasizing the importance of regular heart health monitoring for aging athletes. Despite its limitations, including a small, homogeneous sample, the research opens avenues for further investigation into the effects of endurance sports on heart health across different demographics.
