从半个世纪前心肌梗塞被人们认识以来,它一直是医生最关心的问题之一,也是对现代心脏病学的重大挑战。在美国每年约有40万至60万人死于急性心肌梗塞,而欧洲一些国家冠心病的发病率仍在不断增长。我国近年来的冠心病普查显示,冠心病发病率约为百分之三至五,虽比欧美国家低,但也呈逐年增长趋势。廿年前,大多数医院急性心肌梗塞的住院病死率一直徘徊在百分之三十至四十 It has been one of the doctor’s most concerned issues since it was recognized half a century ago and is also a major challenge to modern cardiology. In the United States, about 400,000 to 600,000 people die of acute myocardial infarction each year, while the incidence of coronary heart disease in some European countries is still on the rise.
