Diverse patterns of myocardial fibrosis in lifelong, veteran endurance athletes
Open accessAbstract
This study examined the cardiac structure and function of a unique cohort of documented lifelong, competitive endurance veteran athletes (>50 yr). Twelve lifelong veteran male endurance athletes [mean ± SD (range) age: 56 ± 6 yr (50–67)], 20 age-matched veteran controls [60 ± 5 yr; (52–69)], and 17 younger male endurance athletes [31 ± 5 yr (26–40)] without significant comorbidities underwent cardiac magnetic resonance (CMR) imaging to assess cardiac morphology and function, as well as CMR imaging with late gadolinium enhancement (LGE) to assess myocardial fibrosis. Lifelong veteran athletes had smaller left (LV) and right ventricular (RV) end-diastolic and end-systolic volumes ( P < 0.05), but maintained LV and RV systolic function compared with young athletes. However, veteran athletes had a significantly larger absolute and indexed LV and RV end-diastolic and systolic volumes, intraventricular septum thickness during diastole, posterior wall thickness during diastole, and LV and RV stroke volumes ( P < 0.05), together with significantly reduced LV and RV ejection fractions ( P < 0.05), compared with veteran controls. In six (50%) of the veteran athletes, LGE of CMR indicated the presence of myocardial fibrosis (4 veteran athletes with LGE of nonspecific cause, 1 probable previous myocarditis, and 1 probable previous silent myocardial infarction). There was no LGE in the age-matched veteran controls or young athletes. The prevalence of LGE in veteran athletes was not associated with age, height, weight, or body surface area ( P > 0.05), but was significantly associated with the number of years spent training ( P < 0.001), number of competitive marathons ( P < 0.001), and ultraendurance (>50 miles) marathons ( P < 0.007) completed. An unexpectedly high prevalence of myocardial fibrosis (50%) was observed in healthy, asymptomatic, lifelong veteran male athletes, compared with zero cases in age-matched veteran controls and young athletes. These data suggest a link between lifelong endurance exercise and myocardial fibrosis that requires further investigation.

DGE was observed in 6 of 12 elite veteran athletes but not in 17 young novice athletes or 20 older non-athletes.
“More recently, Wilson et al. 18 observed DGE in 6 of 12 elite veteran athletes but not in 17 young novice athletes or 20 older non-athletes.”

The Results report LGE in 6 of 12 veteran athletes and none in the 17 young athletes or 20 age-matched controls. But the Methods describe the young athletes as experienced endurance competitors with 11–31 years of training, not novices. The paper calls the imaging finding LGE rather than DGE. (LLM, conf=0.90)
Experimental — accuracy not yet measuredIn a study of 12 veteran male endurance athletes assessed by cardiac MRI, half (6/12) demonstrated late gadolinium enhancement compared to sedentary controls, and years in training and number of competitive marathons predicted prevalence of LGE.
“Similar findings of myocardial fibrosis were presented a few years later in another study involving 12 veteran male endurance athletes who were assessed by cardiac magnetic resonance imaging (MRI) [54]. Specifically, half of them (6/12 athletes) demonstrated late gadolinium enhancement (LGE) compared to sedentary controls. The number of years spent in training (p < 0.001) and the number of”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
