Athletes performing sports on high level are at increased risk for sudden cardiac death. This includes paediatric athletes, even though data on screening strategies in this age group remain scarce. This study aimed to assess electrocardiogram interpretation criteria in paediatric athletes and to evaluate the cost of screening. National, multicentre, retrospective, observational study on 891 athletes of paediatric age (

Background Knowledge about causes of sports-related sudden cardiac arrest (SrSCA) may influence national strategies to prevent such events. Therefore, we established a prospective registry on SrSCA to estimate the incidence and in particular describe the etiologies of SrSCA in the general population in Germany. Methods The registration of SrSCA based upon 4 pillars: a web-based platform to record SrSCA cases in competitive and recreational athletes, media-monitoring, cooperation with the German Resuscitation Registry, and 15 institutes of forensic medicine. Results After an observation period of 6 years, a total of 349 cases was recorded (mean age 48.0 ± 12.7 years); 109 subjects survived. Most of the cases occurred during nonelite competitive or recreational sports. Bystander cardiopulmonary resuscitation (CPR) was initiated in 262 cases (75%); however, rhythm analysis and defibrillation (if indicated) was mainly performed by medical services. In patients ≤ 35 years of age, premature coronary artery disease (CAD) and sudden arrhythmic death syndrome (SADS) prevailed, followed by myocarditis. In athletes ≥ 35 years of age, CAD predominated. Conclusions Country-specific registries are necessary to define the national screening and prevention strategy optimally. In Germany, premature CAD, SADS, and myocarditis are the leading causes of SrSCA in young athletes, reinforcing the great disparity of the prevalence of cardiac diseases among different countries. Extension of on-site SCD-prevention campaigns, with training of CPR and explanation of the efficient use of automated external defibrillators (AEDs), may decrease the burden of SrSCD.

Highlights •Myocarditis is a leading cause of SCD in athletes but diagnosis and risk stratification is challenging. •Using latest data and existing recommendations, we present a new proposed diagnostic flowchart. •Cardiac magnetic resonance imaging can diagnose but may also risk stratify athletes with suspected myocarditis. •Sports behavior counseling may be guided by combining novel noninvasive and invasive tissue characterization methods

Colorectal cancer is a potentially preventable disease, as early lesions may be detected and removed during screening colonoscopy. Emerging evidence suggests associations between cardiovascular disease and several cancers, including colorectal cancer. The relationship is thought to arise from common

Objectives The goal of this study was to define electrocardiographic (ECG) and echocardiographic characteristics of adolescent African athletes. Background Recent observations in African athletes reported large prevalence of left ventricular (LV) hypertrophy and ECG abnormalities. No data, so far, exist for adolescent Africans, which comprise a growing proportion of competitive/professional athletes. Methods The study included 154 soccer players participating at the 8th African Under-17 Championship of 2009, representing Algeria, Burkina Faso, Cameroon, Gambia, Guinea, Malawi, Nigeria, and Zimbabwe. For comparison, 62 Italian players with similar ages, sport achievements, and training schedules were included. Results African athletes showed higher R5/S1-wave voltages than Caucasian athletes (48.6 ± 12.1 mm vs. 34.1 ± 8.9 mm; p Conclusions African athletes displayed large proportion of ECG abnormalities, including a striking increase in R/S-wave voltage, ST-segment elevation, and deeply inverted or diffusely flat T waves by adolescence. LV remodeling in African athletes was characterized by a disproportionate wall thickening than in Caucasians but similar cavity size. Finally, distinctive peculiarities existed in African athletes according to the country (and ethnic) origin.

We congratulate Eijsvogels et al. [(1)][1] on their balanced review concerning the ongoing debate about the “too much exercise hypothesis,” as they had termed it previously [(2)][2]. We fully agree that the published studies on potential harm of too much exercise and especially the following
