急性心肌梗塞是发病后即有死亡危险的病。45％发病后一小时死亡,74％24小时内死亡,因此需要把急性期病人监护治疗。虽然有了各种新疗法,由心律不齐而引起的死亡有所减少,但由心衰休克引起的泵功能不全死亡率仍未减少。影响急性期预后的首先是是否合并有心衰、心律不齐、休克等重症。其次是影响这些合并症的因素,如梗塞部位大小、残存心肌收缩功能等泵功能不全。 Acute myocardial infarction is the risk of death after the onset of the disease. 45% died one hour after onset and 74% died within 24 hours and therefore require acute patient care. Although various new therapies have resulted in fewer deaths due to arrhythmia, the mortality rate of pump insufficiency due to heart failure shock has not diminished. Affect the prognosis of acute phase first is whether the merger with heart failure, arrhythmia, shock and other severe. Followed by the factors that affect these complications, such as the size of infarction, residual myocardial systolic dysfunction such as pump.
