目的对老年急性心肌梗死患者院内心脏性猝死的临床特点进行调查,同时对患者的护理方式进行调查。方法选取本院2012年6月~2014年6月间37例急性心肌梗死猝死患者,对所有患者的临床数据进行调查收集。结果 ST段增高的患者心脏破裂、心源性休克患者要明显多于非增高组,P<0.05差异有统计学意义;非增高组急性肺水肿、室颤人数要明显高于增高组,P<0.05;心脏骤停患者比较两组无差异。结论密切关注患者血样饱和度,并要及时除颤,提升患者生存率。 Objective To investigate the clinical features of sudden cardiac death in elderly patients with acute myocardial infarction and to investigate the patient’s nursing methods. Methods 37 cases of sudden death from acute myocardial infarction in our hospital from June 2012 to June 2014 were selected and the clinical data of all patients were collected. Results In patients with elevated ST segment, heart failure and cardiogenic shock were significantly more than those in non-elevated group (P <0.05). The number of acute pulmonary edema and ventricular fibrillation in non-increased group was significantly higher than that in elevated group (P < 0.05; there was no difference between the two groups in patients with cardiac arrest. Conclusions Pay close attention to the saturation of blood samples, and prompt defibrillation to improve patient survival.
