Background And Purpose:
Lifelong endurance exercise is generally associated with cardiovascular health benefits. However, recent studies suggest that prolonged high-volume training may contribute to coronary atherosclerosis, even in athletes with low traditional cardiovascular risk. This case report aims to explore the cardiovascular status of a master endurance athlete with an exceptionally high lifetime training volume, in light of recent concerns raised in the literature.
Methods:
We present the case of a 60-year-old recreational male marathon runner with no history of cardiovascular disease, who completed over 500 marathons between the ages of 30 and 60 years, covering ∼127 000-km running. In 2024 alone, he completed 60 marathons. Cardiovascular evaluation included clinical risk assessment and coronary computed tomography angiography (CTCA).
Results:
The runner was asymptomatic, had a low ESC-SCORE2 (3.3%), a favorable lipid profile, and normal levels of high-sensitivity C-reactive protein and lipoprotein (a). CTCA revealed no evidence of calcified, mixed, or non-calcified coronary plaques.
Conclusions:
This case highlights that some master athletes may demonstrate resilience to coronary atherosclerosis despite decades of high training volume. In low-risk individuals, prolonged endurance training alone may not necessarily lead to coronary artery disease, emphasizing the need for individualized cardiovascular screening strategies.

01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

01:26Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
