Variation evaluation of biometric and sonographic parameters on left atrial strain values

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Speckle tracking echocardiography is an upcoming modality to quantify left atrial function. Left function disturbed in many disease and systolic strain (LASr) has already been associated with the prognosis fibrillation degree diastolic dysfunction. Some modifying parameters have identified relatively small studies. Purpose We aim assess influence known some unknown biometric sonographic on LASr values a large cohort. Methods This prospective cohort study included 211 individuals assessed general LASr. Patients had normal ejection fraction (≥50%), reasonable image quality frame rate ≥50FPS no significant valvular heart disease. The collected were ventricular fraction, global longitudinal (GLS) volume Index (LAVI). analysis was done offline by semiautomatic contour detection R-R gating used. Results Mean 35.5 ± 11%. There differences for age, (GLS), (LAVI) vendor (GE versus Philips). significantly lower oldest groups (60–69jr 70–84jr) decreasing progression LAVI. when Philips used compared GE. Gender not change Conclusion shows ageing, LAVI, GLS values. difference probably due between two vendors
