“…Of note, these and other studies 66 have found that the ascending aortic root rarely exceeds the clinically accepted upper limits of normal (40 mm) in trained athletes. While we await further study, it seems reasonable to conclude that athletic training alone is not a common cause of marked aortic dilation.…”

Prevalence and Clinical Significance of Aortic Root Dilation in Highly Trained Competitive Athletes

Background-Few data are available that address the impact of athletic training on aortic root size. We investigated the distribution, determinants, and clinical significance of aortic root dimension in a large population of highly trained athletes. Methods and Results-Transverse aortic dimensions were assessed in 2317 athletes (56% male), free of cardiovascular disease, aged 24.8Ϯ6.1 (range, 9 to 59) years, engaged in 28 sports disciplines (28% participated in Olympic Games). In males, aortic root was 32.2Ϯ2.7 mm (range, 23 to 44; 99th percentileϭ40 mm); in females, aortic root was 27.5Ϯ2.6 mm (range, 20 to 36; 99th percentileϭ34 mm). Aortic root was enlarged Ն40 mm in 17 male (1.3%) and Ն34 mm in 10 female (0.9%) subjects. Over an 8-year follow-up period, aortic dimension increased in these male athletes (40.9Ϯ1.3 to 42.9Ϯ3.6 mm; PϽ0.01) and dilated substantially (to 50, 50, and 48 mm) in 3, after 15 to 17 years of follow-up, in the absence of systemic disease. Aortic root did not increase significantly (34.9Ϯ0.9 to 35.4Ϯ2.1 mm; Pϭ0.11) in female athletes. Multiple regression and covariance analysis showed that aortic dimension was largely explained by weight, height, left ventricular mass, and age (R

“…Mutation analysis for the purpose of risk stratification of sudden death, although prominently portrayed in the subspecialty literature, [1][2][3][4][7][8][9][10][11][12]16,[55][56][57][58][59][60][61][62][63][64][65][66][67] has limited practical impact on the present considerations. First, the diagnostic strategy of DNA analysis is time consuming, expensive, and limited to a small number of highly specialized research-oriented laboratories 1,2,8,64 -67 and thus is not yet routinely available to the practicing clinician for the purpose of patient management and formulation of exercise recommendations.…”

“…62,73 • Patients with diseases associated with impaired consciousness (eg, syncope and near-syncope) are subject to considerably higher risk for traumatic injury while engaged in certain sports such as free weight and bench-pressing maneuvers, downhill skiing, diving, ice hockey, rock climbing, motorcycling, and horseback riding, and this factor should be taken into consideration in making recommendations to individual patients with GCVD.…”

Abstract-A group of relatively uncommon but important genetic cardiovascular diseases (GCVDs) are associated with increased risk for sudden cardiac death during exercise, including hypertrophic cardiomyopathy, long-QT syndrome, Marfan syndrome, and arrhythmogenic right ventricular cardiomyopathy. These conditions, characterized by diverse phenotypic expression and genetic substrates, account for a substantial proportion of unexpected and usually arrhythmia-based fatal events during adolescence and young adulthood. Guidelines are in place governing eligibility and disqualification criteria for competitive athletes with these GCVDs (eg, Bethesda Conference No. 26 and its update as Bethesda Conference No. 36 in 2005). However, similar systematic recommendations for the much larger population of patients with GCVD who are not trained athletes, but nevertheless wish to participate in any of a variety of recreational physical activities and sports, have not been available. The practicing clinician is frequently confronted with the dilemma of designing noncompetitive exercise programs for athletes with GCVD after disqualification from competition, as well as for those patients with such conditions who do not aspire to organized sports. Indeed, many asymptomatic (or mildly symptomatic) patients with GCVD desire a physically active lifestyle with participation in recreational and leisure-time activities to take advantage of the many documented benefits of exercise. However, to date, no reference document has been available for ascertaining which types of physical activity could be regarded as either prudent or inadvisable in these subgroups of patients. Therefore, given this clear and present need, this American Heart Association consensus document was constituted, based largely on the experience and insights of the expert panel, to offer recommendations governing recreational exercise for patients with known GCVDs.
