Figure legends
Figure 1. Left atrial strain measures, Doppler measures of diastolic function, and combined atrial/Doppler measurements.
E: peaks of early wave velocity at the mitral valve by pulsed Doppler; e’: early diastolic velocity peaks at tissue Doppler imaging; e’s: septal e’; e’l: lateral e’; e’m: mean septal-lateral e’; LAr: left atriale reservoir; LAcd: left atrial conduit; LAct: left atrial contraction.
Figure 2. Cox univariate regression analyses for all the left atrial measures , according with the presence of a reduced or not left ventricular ejection fraction.
CI: confidence interval; HR: hazard ratio; LAcd: left atrial conduit; LAct: left atrial contraction; LAr: left atrial reservoir; LAr/Eel: ratio between LAr and the ratio between peak of E at pulsed Doppler and mitral lateral e’ at lateral Tissue Doppler Imaging; LAr/Eem: ratio between LAr and the ratio between peak of E at pulsed Doppler and mean mitral septal and lateral e’ at Tissue Doppler Imaging; LAs/Ees: ratio between LAr and the ratio between peak of E at pulsed Doppler and mitral septal e’ at Tissue Doppler Imaging.
Figure 3. Kaplan Meier curves according to the best cut-offs of LASr and LASr/Ees.
LAr: left atriale reservoir; LAr/Ees: ratio between LAr and the ratio between E (peaks of early wave velocity at the mitral valve by pulsed Doppler) and septal e’ (early diastolic velocity peaks at septal mitral tissue Doppler imaging).
