Abstract

In recent years, assessment of left atrial (LA) volumes and function as prognostic markers after acute myocardial infarction (AMI) have gained increasing attention (1). Impairment of both systolic and diastolic left ventricular (LV) function is a frequent finding in patients after AMI and is mainly caused by the amount of infarcted tissue and scar formation (2). The diastolic dysfunction based increase in LA volumes and reduction of LA contractility have been found to be independent predictors for adverse clinical outcome after AMI (1). However, the direct influence of myocardial damage and reperfusion injury obtained by cardiac magnetic resonance (CMR) on LA function is unknown. The aim of the present study was therefore to evaluate the prognostic value of LA function in the setting of acute reperfused ST-segment elevation myocardial infarction (STEMI) and the relationship between LA performance and established CMR markers of myocardial damage. We hypothesized that impaired LA systolic function is associated with myocardial injury and an increased rate of future cardiovascular events.
