Data from Oslo University Hospital Update Knowledge in Acute Myocardial Infarction (The Prognostic Value of Left Atrial Function in Patients with Acute Myocardial Infarction).

A recent study conducted at Oslo University Hospital in Norway examined the prognostic value of left atrial (LA) function in patients with acute myocardial infarction (AMI). The researchers evaluated LA volume and LA strain in 501 AMI patients, including those with atrial fibrillation (AF), and found that left ventricular global longitudinal strain (LV GLS), indexed LA volume (LAVi), and LA reservoir strain were all independently associated with the primary outcome of all-cause mortality and major adverse cardiovascular events. In AF patients, LA reservoir strain remained significantly associated with the primary outcome, suggesting that it may have better prognostic value than LA volume and LV GLS in this population. This research provides valuable insights into the assessment of LA function in AMI patients and highlights the potential of LA strain as a prognostic marker. [Extracted from the article]
