[Acute cardiovascular complications of vigorous physical exertion by untrained persons].
Physical exertion has paradoxical effects: regular physical activity offers protection against cardiovascular diseases, but, on the other hand, it has been shown that strenuous exercise can provoke coronary heart disease and sudden death. The risks of vigorous exertion apply particularly to untrained individuals and persons with a sedentary lifestyle. Physical exertion can cause a myocardial infarction or sudden death in people who were considered perfectly healthy before this event. In most cases, the mechanism of this is probably a rupture at the site of a vulnerable atherosclerotic plaque, with local activation of coagulation. Disturbances in cardiac rhythm may also be a cause of these complications.
