  • Abstract
  • Look Inside

Both a 15-year-old middle (Case 1) and a 16-year-old high school boy (Case 2) suddenly collapsed while running. They were admitted to a hospital. Although Case 1 was resuscitated, he expired on the following day. Case 2 expired 1 hour later. Case 1 revealed coagulation necrosis and contraction band necrosis with hemorrhage in the biventricular myocardium. Case 2 also revealed contraction band necrosis in the biventricular myocardium. No coronary thrombus was found in either boy. In these cases, myocardial necrosis is considered to have been caused by an increase in intramyocytic Ca++ after being recirculated, by an increase in catecholamine under stress or through kinetic cell death rather than by spasm of the coronary artery.
