			==== Prognosis of cardiac arrest in young athletes: ====

			* 58% survival rate was reported by the US Commotio Cordis Registry in 216 persons with sudden cardiac arrest due to commotio cordis (cardiac arrest due to VF triggered by blunt chest trauma) (age range, 0.2-51 years;mean,15years, 95% male) from 2006 through 2012.<ref name=":9">Maron BJ, Haas TS, Ahluwalia A, Garberich RF, Estes NA III, Link MS. Increasing survival rate from commotio cordis.HeartRhythm.2013;10(2):219-223. doi:10.1016/j.hrthm.2012.10.034</ref>
			* Prompt resuscitation and participation in organized competitive sports was associated with higher survival rates. Multivariate analysis identified participation in recreational sports with lower survival (odds ratio [OR] compared with organized competitive sports, 0.33; 95%CI,0.16-0.67) and onsite automated external defibrillator with higher survival (OR, 4.61; 95% CI, 1.43-14.88).<ref name=":9" />
			* Individuals aged 18 to 35 years with sports-related sudden cardiac arrest in Germany and France showed improved survival to hospital discharge with public automated external defibrillator use prior to EMS arrival (OR, 6.25; 95% CI, 1.48 43.20); individuals with sudden cardiac arrest who received both immediate bystander CPR and automated external defibrillator had 91%survival.<ref>Bohm P, Meyer T, Narayanan K, et al.

			* A recent meta-analysis demonstrated that in sports related sudden cardiac arrest, bystander presence (OR, 2.55; 95%CI, 1.48-4.37), bystander CPR (OR, 3.84; 95% CI, 2.36-6.25), and bystander automated external defibrillator use (OR, 5.25; 95%CI,3.58-7.70) were associated with improved survival.<ref>Michelland L, Murad MH, Bougouin W, et al.

			The American Heart Association–American College of Cardiology consensus statement<ref name=":1">Maron BJ, Levine BD, Washington RL, Baggish AL, Kovacs RJ, Maron MS; American Heart Association Electrocardiography and Arrhythmias Committee of Council on Clinical Cardiology, Council on Cardiovascular Disease in Young, Council on Cardiovascular and Stroke Nursing, Council on Functional Genomics and Translational Biology, and American College of Cardiology. Eligibility and disqualification recommendations for competitive athletes with cardiovascular abnormalities: Task Force 2: preparticipation screening for cardiovascular disease in competitive athletes: a scientific statement from the American Heart Association and AmericanCollege of Cardiology. Circulation. 2015;132(22):e267-e272.</ref> on preparticipation screening recommends the American Heart Association 14-point screening guide, including a comprehensive history taking and a physical examination for young athletes (class I recommendation), but does not recommend routine ECG screening of young adults (athletes and non-athletes) in the general population (class III), due to concerns about diagnostic accuracy, cost-effectiveness, and availability of physicians and equipment needed for screening. ECG or transthoracic echocardiography should only be performed in select individuals in whom genetic,congenital,or other cardiovascular abnormalities are suspected or identified (class IIb).<ref name=":1" />

			However, recent ESC guideline recommends a 12-lead ECG as part of preparticipation for all competitive athletes younger than 35 years (class IIa).<ref name="pmid36017572" /> This recommendation was supported by outcome data from the Veneto region, which showed declining incidence of sudden death in young competitive athletes after introduction of a nationwide prescreening program using ECG.<ref>Corrado D, Basso C, Pavei A, Michieli P, Schiavon M,ThieneG. Trends in sudden cardiovascular death in young competitive athletes after implementation of a preparticipation screening program. JAMA.2006;296(13):1593-1601. doi:10.1001/jama.296.13.1593</ref> Some data suggest that compared with history and physical examination, ECG may provide superior accuracy to identify potential risk of sudden death, primarily due to detection of preexcitation syndromes (sensitivity 88% vs 19%, specificity 98% vs 75%).<ref>Williams EA, Pelto HF, Toresdahl BG, et al. Performance of the American Heart Association (AHA)14-point evaluation versus electrocardiography for the cardiovascular screening of high school athletes: a prospective 996 study.

			In the last 2 decades, preparticipation screening for early identification of young competitive athletes at risk of sudden cardiac arrest in high school, college, and professional settings has been investigated. A comparable incidence of cardiovascular deaths was found between 1993 and 2015 in these studies screening competitive athletes. In the Veneto region of Italy, where ECG is routinely employed as part of preparticipation screening, and those in the US (Minnesota), where preparticipation prescreening is limited to history and physical examination.<ref>Maron BJ, Haas TS, Doerer JJ, Thompson PD, Hodges JS.
