背景：心脏磁共振(CMR)所得的左房(LA)应变、射血分数(LAEF)和指标容量(Lavi(Max)和Lavi(Min))对ST段抬高心肌梗死(STEMI)后的预后价值仍存在争议。本研究的目的是评估左房功能与STEMI后主要不良心血管事件(MACE)的关系。方法：共有202名在STEMI后中位数第4天接受CMR的前瞻性招募患者有完整的CMR数据用于特征跟踪评估。结果：35名患者在607天的中位随访期内发生了MACE。MACE患者左房储备区应变中位数较低(18.9%vs.29.4%，P
Background: The prognostic value of cardiac magnetic resonance (CMR) derived left atrial (LA) strain, ejection fraction (LAEF) and indexed volumes (LAVI(max) and LAVI(min)) after ST-elevation myocardial infarction (STEMI) remains controversial. The aim of this study was to assess the relationship between LA function and major adverse cardiovascular events (MACE) after STEMI.Methods: A total of 202 prospectively recruited patients who underwent CMR at median day 4 after STEMI had complete CMR data for feature tracking assessment. LA reservoir and booster strain were quantified based on the average of three independently repeated measurements.Results: MACE occurred in 35 patients during a median follow up of 607 days. Patients with MACE had lower median LA reservoir strain (18.9% vs. 29.4%, P
