心肌梗死约有40～75％死于症状出现后1小时内,而所有冠心病死亡者中约60％死于医院之外。送进冠心病监护室而获得生存者是很少的。就是在医院进行治疗,包括高压氧或主动脉球囊泵等技术的使用,亦无法预计其效果。即使存活,仍有发生心力衰竭或再次梗死的危险。流动冠心病监护单位的救护车,对发作初期出现心律失常的患者的抢救是有帮助的。有人报告,增加流动救护车监护,可使医院冠心病室内的死亡率减少3倍。
About 40-75% of myocardial infarctions die within 1 hour of symptom onset, and about 60% of all deaths from coronary heart disease die outside the hospital. Few survivors are admitted to the CHD. It is in the hospital for treatment, including the use of hyperbaric oxygen or aortic balloon pump and other technologies, can not predict the effect. Even if alive, there is still the risk of heart failure or reinfarction. Ambulatory ambulatory care unit mobile ambulance, early onset of arrhythmias in patients with salvage is helpful. It has been reported that increasing ambulatory ambulatory care can reduce the rate of death in hospital coronary heart disease by three-fold.
