急性心肌梗塞(AMI)未在发病当时心脏骤停者在发病时的急救十分重要。国内外的经验证明,AMI在发病时妥善急救者在头24小时死亡率为2.5～5％,若AMI的发病当时急于转诊,未能就地急救者,头24小时内的死亡率可高出5～10倍。因此有必要重视AMI的当时急救。 一、AMI发病时的病理生理改变 心脏的冠状动脉因粥样斑块破碎、脱落、出血及/或冠脉严重痉挛导致冠脉突然闭塞,此时该区域心肌立即缺血,称之为“缺血期”。此时一部分
Acute myocardial infarction (AMI) is not in the onset of cardiac arrest at the onset of the first aid is very important. Domestic and foreign experience shows that the AMI at the onset of proper first aid in the first 24 hours of mortality was 2.5 to 5%, if the onset of acute myocardial infarction was urgent referral, failure to first aid, the first 24 hours of high mortality can be high Out 5 to 10 times. Therefore, it is necessary to pay attention to AMI’s first aid. First, the pathological changes in the pathogenesis of AMI Cardiac coronary heart disease due to atherosclerotic plaque broken, shedding, bleeding and / or severe coronary spasm lead to sudden coronary occlusion, when the region immediately ischemic myocardium, called “missing Blood period. ” At this time part
