Left atrial mechanical function and clinical performance in non-dilated versus dilated cardiomyopathy

LA conduit strain is a promising noninvasive parameter for identifying functional and structural differences between NDLVC and DCM. Its strong association with exercise capacity and ability to differentiate phenotypes may support its integration into clinical assessment and follow up,particularly in clarifying structural and functional differences in non-ischemic remodeling patterns. These findings suggest that preserved LA conduit function in NDLVC may reflect a less hemodynamically burdened atrial profile, which is consistent with better clinical performance and functional capacity.
