Has the presence of delayed enhancement been documented in athletes performing strenuous exercise?
['Atypical findings such as marked cardiac dilation, reduced deformation, or small patches of delayed gadolinium enhancement may be commonly encountered in well-trained athletes, but, at present, the prognostic significance of such findings is unknown. ', 'On CMR, DGE localized to the interventricular septum was identified in 5 of 39 athletes who had greater cumulative exercise exposure and lower RVEF (47.1 ± 5.9 vs. 51.1 ± 3.7%, P = 0.042) than those with normal CMR.', 'Post-event cardiac MRI demonstrated the interval appearance of delayed enhancement of gadolinium at the inferior insertion of the right ventricle and in the interventricular septum-a novel finding that may represent subtle inflammation secondary to a combined exercise and altitude effect.', 'No evidence of delayed enhancement of the left ventricular myocardium was found on CMR imaging, suggesting that the increase in cardiac biomarkers after the marathon may not have be due to myocardial necrosis.', 'Of the 102 runners, five had a CAD pattern of LGE, and seven had a non-CAD pattern of LGE. The CAD pattern of LGE was located in the territory of the left anterior descending coronary artery more frequently than was the non-CAD pattern (P = .0027, Fisher exact test). The prevalence of LGE in runners was higher than that in age-matched control subjects (12% vs 4%; P = .077, McNemar exact test).']
['There are contrasting literature data on the presence of delayed enhancement, as a sign of myocardial fibrosis, in healthy athletes. More studies are necessary to define the presence, incidence and severity, as well clinical and prognostic meaning, of delayed enhancement magnetic resonance in healthy athletes.']
