Provides normative LA strain data in healthy adults; leaves open its diagnostic or prognostic role pending validation in disease cohorts.
Cameli et al. (2009) conducted a cross-sectional in Healthy subjects (n=60). Two-dimensional speckle tracking echocardiography was evaluated on Global peak atrial longitudinal strain (PALS). Two-dimensional speckle tracking is a feasible technique for assessing left atrial longitudinal deformation, establishing a normal global peak atrial longitudinal strain of 42.2% in healthy subjects.
