对急性心肌缺血综合征和超急性损伤期心肌梗塞的诊断和处理认识的提高,可改善患者预后,减小梗塞范围,减少并发症,减低死亡率。一、急性心肌缺血综合征的诊断:急性心肌缺血综合征属于不稳定型心绞痛,此种心绞痛如处理不妥善则预后差,约20%在半年内发生急性心肌梗塞,有时则为急性心肌梗塞的先兆表现,心电图ST段明显降低,在没有恢复正常时则转变为急性心肌梗塞的图形。心绞痛发作期间可出现急性左心衰竭、心源性休克、心律失常等并发症,处理不当往往危及生命。下列几点提示急性心肌缺血综合征:(一)心绞痛发作严重、剧烈,持续时间较长,或短期内反复发作多次。(二)经常规镇静、应用硝酸甘油类药物、或高血
Improve awareness and diagnosis of acute myocardial ischemia syndrome and hyperacute injury myocardial infarction can improve patient prognosis and reduce infarct size, reduce complications and reduce mortality. First, the diagnosis of acute myocardial ischemia syndrome: acute myocardial ischemia syndrome is unstable angina pectoris, such angina if handled properly, the prognosis is poor, about 20% of acute myocardial infarction within six months, and sometimes acute myocardium The prognosis of infarction, ECG ST segment was significantly reduced, did not return to normal in the case of acute myocardial infarction graphics. Angina may occur during acute heart failure, heart failure, cardiac arrhythmia and other complications, improper handling often life-threatening. The following points suggest acute myocardial ischemia syndrome: (a) severe angina pectoris, severe, longer duration, or repeatedly repeated short-term. (B) regular calm, the use of nitroglycerin drugs, or high blood
