Left atrioventricular coupling and left atrial abnormality in patients with acute myocardial infarction with and without hyperglycemia assessed with 3.0T cardiac magnetic resonance imaging feature tracking.

ABSTRACT:

Background

The relationship between stress hyperglycemia and left atrial (LA) abnormality and left atrioventricular coupling in patients with acute myocardial infarction (AMI) has not been fully explored. This study aimed to assess the additive effect of hyperglycemia on LA phasic function and to investigate the atrioventricular interaction in patients with AMI via cardiac magnetic resonance imaging (MRI).

Methods

This study comprised 120 patients with AMI with admission normoglycemia (aNGL), 88 patients with AMI and admission hyperglycemia (aHGL), and 70 age- and sex-matched controls. LA volume (LAV), LA ejection fraction (LAEF), and LA reservoir/conduit/contraction strain (εs/εe/εa) were measured and compared. Subgroup analysis was performed according to the presence of LA
