  1. Cardiovascular risks to young persons on the athletic field.

    Article - En anglais

    Sudden cardiac deaths of young athletes, which are usually associated with physical exertion, continue to achieve high public visibility and generate considerable concern.

    Despite broad community participation in sports, such catastrophes are uncommon, occurring in about 1/200 000 high school athletes per academic year.

    Various unsuspected congenital cardiovascular diseases are usually responsible ; the most common lesions are hypertrophic cardiomyopathy and several congenital coronary artery anomalies.

    Selected reports suggest that arrhythmogenic right ventricular dysplasia may be a more common cause of these deaths than previously suspected.

    In some trained athletes with borderline increases in thickness of the left ventricular wall, mild morphologic expression of hypertrophic cardiomyopathy can often be distinguished from the physiologic consequences of athlete's heart by noninvasive clinical assessment and testing.

    In addition, the recognized cardiovascular risks of the athletic field are now extended to include cardiac arrest resulting from relatively modest, nonpenetrating chest blows produced by projectiles (such as baseballs) or bodily contact in the absence of underlying cardiac disease and without structural injury to the chest wall or heart.

    These uncommon but usually fatal events seem to result when chest impact occurs precisely during the vulnerable phase of repolarization, and they may be reduced by use of softer baseballs. (...)
