Association of ascending aortic dilatation and long-term endurance exercise among older masters-level athletes
JAMA Mar 03, 2020
Churchill TW, Groezinger E, Kim JH, et al. - This study sought to evaluate the prevalence of aortic dilatation among long-term masters-level male and female athletes with about 2 decades of exercise exposure. A cross-sectional study was performed to explore aortic size in veteran endurance athletes. Between February 2018, and October 2018, masters-level rowers and runners aged 50 to 75 years were obtained from competitive athletic events across the United States. The aortic size at the sinuses of Valsalva and the ascending aorta, measured using transthoracic echocardiography in accordance with contemporary guidelines was the primary endpoint. This study included a total of 442 athletes (mean [SD] age, 61 [6] years; 267 men [60%]; 228 rowers [52%]; 214 runners [48%]). Clinically relevant aortic dilatation was found to be common among aging endurance athletes, increasing the possibility of vascular remodeling in response to long-term exercise. Longitudinal follow-up is assured to ascertain corollary clinical outcomes in this population.
