心脏猝死是指自然发生、出乎意料和突然的死亡。世界卫生组织关于心脏猝死的定义是在起病后6小时以内死亡。我们认为应该是在症状发作后1小时内死亡者。在美国,每年约有70万人死于冠心病,其中65％是猝死。在所有死亡者中,32％是由于心脏病猝死,因此,这一问题比肿瘤更为重要。男女两性的平均寿命是男性70岁,女性76岁,主要是因男性猝死较女性高4倍。如果呼吸道疾病能被控制,则寿命可延长2年;如肿瘤能被控制,则可延长3年,如冠心病可被控制, Sudden cardiac death refers to the natural, unexpected and sudden death. WHO’s definition of sudden cardiac death is death within 6 hours of onset. We think it should be within 1 hour after the onset of symptoms. In the United States, about 700,000 people die of coronary heart disease each year, of which 65% are sudden death. Thirty-two percent of all deaths are due to sudden cardiac death and the problem is therefore more important than cancer. The average life expectancy of men and women is 70 for men and 76 for women, mainly due to a 4-fold higher death rate from men than women. If the respiratory disease can be controlled, the life expectancy can be extended for 2 years; if the tumor can be controlled, you can extend for 3 years, such as coronary heart disease can be controlled,
