Left atrial strain analysis and new-onset atrial fibrillation in patients with ST-segment elevation myocardial infarction: A prospective echocardiography study.

Background: New-onset atrial fibrillation (NOAF) is a well-known complication of ST-segment elevation myocardial infarction (STEMI), probably due to left atrial (LA) remodelling. LA strain (LAS) can predict NOAF in several cardiovascular diseases.

Objective: To assess whether LAS predicts NOAF in sinus rhythm patients with STEMI during hospitalization.

Prognostic Value of Right Ventricular Longitudinal Shortening Fraction in Patients With ST-Elevation Myocardial Infarction: A Prospective Echocardiography Study.

Right ventricular systolic dysfunction (RVsD) frequently occurs in patients with ST-elevation myocardial infarction (STEMI). However, the diagnosis depends on the echocardiographic parameters to define RVsD. The right ventricle longitudinal shortening fraction (RV-LSF) is an accurate and reproducible 2-dimensional speckle-tracking parameter associated with clinical events in various pathologies.
