Figure 5. Extremely large coronary arteries in a lifelong endurance exerciser.

Figure 5.

Diagrammatic representation of the left main coronary artery 0.5 cm from the ostium from an autopsy study of a lifelong champion runner (Clarence “Mr. Marathon” DeMar; A) and a “control” patient who died at a similar age (B). A lifetime of endurance exercise training was associated with a very large coronary artery lumen diameter in DeMar. Redrawn from photographs in Currens and White (80). Created with BioRender.com.
