Is coronary artery calcification in highly active people like marathon runners associated with increased risk of death?

(JAMA Network) Some studies have suggested that people with high levels of physical activity way beyond current physical activity guidelines, such as marathon runners, can have significant build-up of calcium in the arteries of their heart called coronary artery calcification (CAC). But data are limited about the risk of death in these highly active people with CAC. This study included nearly 22,000 men (average age almost 52) with varying levels of self-reported physical activity and who underwent CAC scanning.
