A 38-year-old man (Case 1) suddenly collapsed while resting. His 54-ye
ar-old brother (Case 2) came soon thereafter began to perform cardiac
massage and mouth-to-mouth resuscitation. However, the elder brother s
uddenly died after resuscitating his younger brother for about 30 minu
tes. Necropsy revealed an occlusive thrombus of the left anterior desc
ending coronary artery and coagulation necrosis of the myocardium in C
ase 1. Case 2 was diagnosed as sudden cardiac death on the basis of th
e moderate coronary sclerosis and myocardial lesions including contrac
tion band, fragmentation, waviness, bleeding, and mild subendocardial
fibrosis. Pulmonary edema in the both cases revealed the presence of l
eft ventricular heart failure. Case 2 is a good example of the contrib
ution of psychological and physical stress to sudden cardiac death.
