冠心病急性发作(如急性心肌梗塞)的现场处理十分重要,有统计资料表明,冠心病死亡病例有三分之二是死于医院外的。对于急症,人们往往存在急于送院治疗的心情,对冠心病发作的病人来说,不作任何现场处理,就匆忙转送医院,是十分危险的。 冠心病的发生,主要是冠状动脉发生粥样硬化,致使动脉管腔变窄,血液供应受到影响。当心脏工作量增大,心肌需要更充足的血液时,因得不到足够的血液供应,发生缺血缺氧,就造成心绞痛。当较大的冠状动脉分支发生急性闭塞,使由此血管供应血液的心肌营养完全断绝,导致心肌梗塞。因此,无论是心绞痛,还是心肌梗塞发生时,都应
On-site treatment of acute attacks of coronary heart disease (such as acute myocardial infarction) is important, and statistics show that two-thirds of all deaths from coronary heart disease die outside the hospital. For acute illness, people often have the mood to rush to hospital for treatment. For patients with coronary heart disease, it is very dangerous to rush to the hospital without any on-site treatment. Coronary heart disease, mainly coronary atherosclerosis, resulting in arterial narrowing of the lumen, the blood supply affected. When the heart workload increases, the myocardium needs more blood, because of insufficient blood supply, ischemia and hypoxia, causing angina. When a larger occlusion of the coronary artery occurs an acute occlusion that completely sequesters cardiac muscle nutrients supplied by the blood vessels, resulting in a myocardial infarction. Therefore, whether it is angina or myocardial infarction occurs, should be
