|Acute aortic dissection results from a split in the intima and media of the aortic wall, with the subsequent foundation of a false in the outer half of the media and elongation of this channel by pulsatile blood flow. It has been speculated that the very high blood pressure generated during the lifting of weights, particularly with staining accompanied by a Valsalva maneuver, may be the cause of an aortic intimal tear.
