Results (1)The permillage of myocyte apoptosis in infarct area in elder patients with sudden death caused by AMI was significantly higher than that in control group(663.00‰±117.12‰ vs 34.30‰±20.68‰,P＜0 .01).However the permillage of myocyte apoptosis in 1-vessel,2-vessel,and 3 - vessel disease were 514.28±165.12‰,564.38‰±102.33‰ and 668.25‰±127. 19‰,respectiverly,significantly higher as compared to control group(All P＜ 0.01).But no significance was found among the three groups.(2)The size of DNA f ragment about 180～200 bp was found only in those patients with two and three ve ssels involoved.(3)The electron microscope showed the characteristics of myocyte apoptosis episodes,the others showed the characteristics of necrosis.
