Aortic dilatation is common in older endurance athletes, suggesting the vessel may remodel in response to long-term exercise, a cross-sectional study reveals.

US researchers assessed the prevalence of aortic dilatation among 442 elite rowers and runners (mean age 61, 60% men, 52% rowers) who were enrolled in competitive athletic events across the US in 2018.
