Why the study?
Physical activity reduces cardiovascular event risks, but studies report an increased prevalence of coronary atherosclerosis and calcification among middle-aged and older athletes. This review aims to understand the potential adverse effects of high-dose exercise training on coronary arteries and guide clinical management.

Higher CAC in athletes warrants no change in exercise advice; leaves open whether plaques increase events versus sedentary peers.
Does physical activity and exercise training increase coronary atherosclerosis in middle-aged and older athletes?
While high-dose exercise in middle-aged and older athletes is associated with increased coronary artery calcification, the plaques tend to be more calcified and less mixed, suggesting a more benign composition.
