高龄急性心肌梗死患者院前延误时间的相关研究

摘要

Objective To investigate the differences of pre-hospital delay time in acute ST-elevation myocardial infarction (STEMI)between the advanced age group(>75 years old)and control group(≤75 years old).Methods Four hundreds patients with STEMI in the cardiology and emergency departments of the First Affiliated Hospital and Affiliated Luoyang Central Hospital of Zhengzhou University from January 2013 to March 2015 were selected and divided into two groups according to the age,the ad-vanced age group (>75 years old)and control group(≤75 years old).The patients′data were inquired and recorded for conducting the statistical analysis.Results The proportion of pre-hospital delay time < 6 h in the advanced age group was significantly lower than that in the control group and the time for conducting coronary angiography was longer than that in the control group,the differences were statistically significant(P <0.05).The mortality rates of intra-hospital,on 30 d and half a year after discharge in the advanced age group were higher than those in the control group,the differences between the two groups were statistically signif-icant (P <0.05).Conclusion The advanced age patients receiving active therapy are relatively less,which is mainly due to the wor-ry on the age related adverse reactions.%目的：探讨高龄患者（＞75岁）和对照患者（≤75岁）急性 ST 段抬高型心肌梗死（STEMI）患者院前延误时间的差异。方法选择2013年1月至2015年3月就诊于郑州大学第一附属医院及郑州大学附属洛阳中心医院心血管内科及急诊科的STEMI 患者400例。所有入选患者根据年龄分为两组，即高龄组（＞75岁）和对照组（≤75岁）。询问并记录患者资料并进行统计学分析。结果高龄组患者院前延误时间小于6 h 的比例明显低于对照组，行冠状动脉造影术的时间长于对照组，差异有统计学意义（P ＜0．05）；高龄组患者院内，出院后30 d 及半年病死率均高于对照组，差异有统计学意义（P ＜0．05）。结论高龄患者接受积极治疗者相对较少，这主要是因为对年龄相关的不良反应方面存在担心。
