Background: Studies have suggested that extreme exercise may have negative cardiac effects. We hypothesized that endurance athletes would have a higher plaque burden as measured by Computed Tomography (CT) calcium scores when compared to shorter distance competitive runners.
Methods: We recruited 85 runners who have run competitively for more than 10 years. Group A consisted of runners who have competed in ultramarathons (>50 kilometers) or ironman races, Group B consisted of marathon runners who have competed in at least 10 marathons or in 10 years. Group C consisted of short distance runners (half marathons or less) who have competed in at least 10 races in 10 years.
Results: Of the 85 male and female runners, 23 runners were excluded from primary analysis due to risk factors for Coronary Artery Disease (CAD) (family history of CAD, hypertension, diabetes, hyperlipidemia, or remote tobacco use). There was no significant difference between Group A+B vs. C with regards to age (58.3 vs. 59.4, p=ns), years of running (30.5 vs. 29.1 p=ns) or miles/week running (42.1 vs. 3702, p=ns). There was a significant difference between Group A+B vs. C with regards to percentage of runners with calcium score >0(74vs. 21, p=.0001), calcium score > than the 50% as compared to a national database (71 vs. 18, p=.001), and calcium score > than 100(41 vs. 11, p=.0069). In the subgroup of women there was also a significant difference between Group A+ B vs. C with regards to percentage of runners with calcium score greater than 50% (71.4 vs. 7.7, p=.0014). In the overall cohort men were twice as likely as women to have an elevated calcium score >0 (60%vs. 30% p=.03), and calcium score >50th percentile (57% vs. 25%, p=.02) There was no difference between groups A vs, B with regards to score >0(76 vs. 67, p=ns), 50 % (71vs. 67, p-=ns) or score >100 (38 vs. 22, p=ns). In addition, there was no significant difference in aortic root size (mm) between Group A+B vs. C (34.8vs.36.35, p=ns)
Conclusions: Ultra distance and marathon runners had a much higher plaque burden when compared to short distance runners as measured by CT calcium scores.
