Overview
Left atrial cardiomyopathy (LACM) is frequently underdiagnosed but plays a key role in increasing the risk of atrial fibrillation (AF) and thromboembolic events. While atrial strain is a validated marker of LACM, its measurement with conventional echocardiography can be time-consuming and less feasible in acute settings. The use of AI-assisted echocardiography (AI-echo) may help streamline image acquisition and analysis, offering faster and potentially more accurate assessment.
This study aims to compare the time required for atrial strain analysis using AI-echo versus standard methods. It also explores how changes in strain parameters (LASr, LASct, LAScd) relate to the onset of AF and in-hospital adverse outcomes, adjusting for comorbidities and conventional echo variables.
Main endpoints include time reduction with AI-echo and the association between strain changes and AF, complications, or mortality during hospitalization.
Eligibility
Inclusion Criteria:
- Age between 18 and 85 years.
- Hospitalization in CCU for acute cardiac pathology (e.g. acute coronary syndrome, acute or exacerbated heart failure, malignant arrhythmias, etc.).
- Ability to provide written informed consent.
Exclusion Criteria:
- Severe hemodynamic instability, history to contraindicate the execution of the echocardiographic examination.
- Severely inadequate echocardiographic window that precludes atrial or ventricular morpho-functional assessment.
- Inability to continue the study for clinical reasons, logistics or patient refusal.
