研究背景:心房颤动(简称房颤)在心肌梗死患者中较为常见,但事实上,房颤在心肌梗死急性期的重要性并未被临床医生广泛重视。而且它对于心肌梗死预后的潜在影响仍存在争议。更进一步来讲,现有数据对于房颤致死风险的矛盾焦点主要集中在房颤发作持续时间上。本文首开先河,就此焦点问题做一系统性回顾和荟萃分析,旨在为心肌梗死合并房颤患者死亡风险及其与房颤发作持续时间的相关性做一定量分析。
Background: Atrial fibrillation (AF) is more common in patients with myocardial infarction, but in fact, the importance of atrial fibrillation in the acute stage of myocardial infarction has not been widely recognized by clinicians. And its potential impact on the prognosis of myocardial infarction is still controversial. Furthermore, the focus of the current data on the risk of death from AF is mainly focused on the duration of AF episodes. This article first opened the door to do a systematic review and meta-analysis of the focus of this issue, designed to myocardial infarction patients with atrial fibrillation risk of death and its relationship with the duration of atrial fibrillation to do a certain amount of analysis.
