The value of left atrial strain for predicting left ventricular reverse remodeling in dilated cardiomyopathy patients

Motivation: The structure and function of left atrial (LA) have shown significant value in prognostic and risk stratification in dilated cardiomyopathy (DCM) patients. But no previous studies had reported its value for predicting left ventricular reverse remodeling (LVRR) in DCM. Goal(s): This study aimed to explore whether fast long-axis strain (FLAS) of LA can provide predictive value. Approach: LA strain and other cardiac magnetic resonance (CMR) parameters were measured by CVI (version 5.13.7) in 96 patients. Statistical analysis was performed using SPSS. Results: Both LACS and LGE were independent predictors of LVRR. The combination of LACS and LGE provided better prediction performance. Impact: For the first time, our study demonstrated the predictive value of LA strain for LVRR. It would be beneficial for DCM patients who were contradictive to contrast agencies.
