Observational analysis demonstrates that baseline LACI predicts adverse left ventricular remodeling in STEMI patients, suggesting early risk assessment benefits.
Motivation: To clarify the correlation between left atrial conduction delay index (LACI) and adverse left ventricular remodeling (ALVR) in ST-segment elevation myocardial infarction patients. Goal(s): To identify independent predictors of ALVR. Approach: 143 STEMI patients undergoing CMR at 5±3 days and 6 months post-infarction were enrolled. LACI and other factors were analyzed. Results: Baseline LACI was an independent predictor of ALVR (OR=1.035, p=0.048), suggesting its potential use in early risk stratification. Impact: The impact of this study clarifies that baseline LACI in STEMI patients independently predicts ALVR after 6 months. This finding introduces a novel CMR parameter for early risk stratification, potentially guiding clinical interventions and enhancing patient outcomes.
