老年急性心肌梗死后猝死的危险因素分析

摘要

目的分析老年急性心肌梗死后猝死的危险因素。方法选取本院2012年1月～2015年1月收治的207例老年急性心肌梗死患者进行研究。结果39例猝死患者中男女比为2：5；发病前有情绪应激18例；有高血压、脑卒中史为7例和26例；梗死时有心衰18例；梗死时有低血压或休克14例；QRS低电压例；室内传导阻滞7例；与未猝死老年急性心肌梗死患者比较，差异有统计学意义（P＜0.05）。结论通过研究可以了解到，造成急性心肌梗死后猝死的最主要因素就是恶性心律不齐，如果患者的心脏负荷加重，就会导致患者出现恶性心律不齐的症状，而造成患者心脏负担加重的主要因素包括情绪不稳、精神紧张以及过度劳累等。%Objective To analyze the risk factors of sudden death in elderly patients with acute myocardial infarction. Methods207 patients with acute myocardial infarction were studied from January 2012 to January 2015.Results39 cases of sudden death patients, male to female ratio 2:5, prior to the onset of emotional stress in 18 cases, 7 cases and 26 cases of hypertension, stroke history. Infarction with heart failure in 18 cases. Infarction with hypotension or shock in 14 cases. QRS low voltage cases. 7 cases of intraventricular conduction block, and no sudden death in patients with acute myocardial infarction compared, the difference is statistically signiifcant (P<0.05).Conclusion Through the research can understand that the main factors of sudden death caused by acute myocardial infarction is malignant arrhythmia, if patients with cardiac load increase will lead to patients with malignant arrhythmia symptoms appear, caused the main risk factors of patients with heart burden include emotional instability, mental stress and overwork.
