本文对发病后24h 内入院的68例老年 AMI 患者 CPK 峰值、放射性核素心血管造影、心肌显像、住院期间主要合并症及预后与有无心肌缺血病史的关系,进行了临床观察。结果表明:平均 CPK 峰值、LVEF<40%、左室壁明显运动障碍、左室壁放射性稀疏及/或缺损区存在≥2处、住院期间室性心律失常、心衰,心源性体克及死亡发生率,在无心肌缺血病史组均明显高于有心肌缺血病史组。提示无心肌缺血病史者较有心肌缺血病史者的 AMI 面积大,心功能损害较明显、预后较差。在处理上,对无心肌缺血病史者的 AMI 要更加注意。
In this paper, 68 cases of elderly patients admitted within 24 hours of AMI patients with CPK peak, radionuclide cardiovascular imaging, myocardial imaging, major complications during hospitalization and prognosis with or without history of myocardial ischemia, the clinical observation. The results showed that the average CPK peak, LVEF <40%, significant left ventricular dyskinesia, left ventricular wall sparseness and / or defect area there are 2, ventricular arrhythmia, heart failure, heart-derived body grams and The incidence of death in patients with no history of myocardial ischemia was significantly higher than those with history of myocardial ischemia. Prompted no history of myocardial ischemia in patients with history of myocardial ischemia AMI area, cardiac dysfunction more obvious, the prognosis is poor. In the treatment, no history of myocardial ischemia AMI should pay more attention.
