Left Atrial Remodeling Following ST-Segment-Elevation Myocardial Infarction Correlates With Infarct Size and Age Older Than 70 Years.

ABSTRACT: Background Following myocardial infarction, left ventricular remodeling (LVR) is associated with heart failure and cardiac death. At the same time, left atrial (LA) remodeling (LAR) is an essential part of the outcome of a wide spectrum of cardiac conditions. The authors sought to evaluate the correlates of LAR and its relationships with LVR after myocardial infarction. Methods and Results This is a retrospective analysis of 320 of 443 patients enrolled for study of LVR after ST-elevation myocardial infarction. Left ventricular (LV) volumes, infarct size and LA volume index were assessed by cardiac magnetic resonance imaging during index hospitalization (day 6 [interquartile range, 4-8]) and after a 3-month follow-up. LAR was studied using a linear mixed model for repeated measurements. Ov
