Correlations between left atrial volumes and strains in healthy adults: Detailed analysis from the three‐dimensional speckle‐tracking echocardiographic MAGYAR‐Healthy Study

Introduction Little is known about the relationship between left atrium (LA) volumes and contractility features along cardiac cycle. The present study aimed to assess, by three-dimensional speckle-tracking echocardiography (3DSTE), correlations LA volumes, volume-based functional properties, strains during cycle in healthy adults. Methods We included 217 adult volunteers (mean age 33.4 ± 12.7 years, 112 males) who underwent complete two-dimensional Doppler with 3DSTE. Results stroke were greater subjects maximum volume (Vmax ) reservoir, conduit, booster pump phases of function. While emptying fraction reservoir phase was not different depending their Vmax value, a significantly lower could be detected conduit whose >50 mL. In function, whatever . Only global mean segmental peak radial strain (RS) 3D (3DS) same at atrial contraction appeared , whereas other parameters different. Conclusions subjects, LA-RS LA-3DS, objective contractility, are up point beyond which this association disappears.
