Key Aspects of Marathon Running and Heart Health:

Long-Term Risks: Some studies suggest that lifelong, extreme endurance training might lead to higher coronary artery plaque, myocardial fibrosis (scarring), and an increased risk of atrial fibrillation.
Sudden Cardiac Death: While rare, the risk of sudden death during a marathon exists, usually due to underlying, undetected coronary artery disease.
Survival Rates: Marathon runners are generally better able to survive cardiac events compared to sedentary individuals.

Benefits of Training: Moderate to high-volume training reduces blood pressure and arterial stiffness, improving overall cardiovascular fitness.
Acute Effects: Immediately following a marathon, runners may experience temporary right ventricle dilation and increased levels of heart-related enzymes (biomarkers), which usually resolve within a week
