“…2,3 In recent studies, a new Doppler index -the ratio of E to e' multiplied by peak systolic mitral annular velocity (s') derived by Doppler tissue imaging (E/(e'xs'), is demonstrated to be superior to E/ e', e', s', or E in sinus rhythm (SR) patients and has high diagnostic accuracy, particularly in patients with intermediate values for E/e' ratio (8)(9)(10)(11)(12)(13)(14)(15). 4 Elevated E/e' ratio and to a lesser extent E/(e'xs') have been confirmed as beneficial predictors of new-onset AF, AF recurrence after electrical cardioversion (ECV), and worse outcomes in patients with various heart diseases. [5][6][7][8][9][10] A comprehensive systematic review by D. Kotecha reported that diastolic function indices, particularly E/e', are valid and reproducible in patients with AF when the appropriate cardiac cycles are carefully selected.…”

Purpose: Spectral tissue Doppler-derived E/e' ratio has been proposed as the best parameter for prediction of atrial fibrillation (AF). Relaxation and contraction are equivalent parts of a continuous cardiac cycle, where systolic and diastolic abnormalities have a variable contribution to the left ventricle (LV) failure. The aim of this study was to investigate whether the E/(e'xs') ratio is a better index than E/e' to predict AF recurrence and to determine the changes of spectral tissue Doppler indices 1 month after the electrical cardioversion (ECV). Patients and Methods: The study included 77 persistent AF patients with restored sinus rhythm (SR) after ECV. Only patients with normal LV ejection fraction (EF) were included. Echocardiography and NT-proBNP laboratory findings were performed. A primary outcome was the early (within 1 month) recurrence of AF. Results: After a 1 month follow-up period, 39 patients (50.6%) were in SR. E/e′ (HR=1.74, P=0.001) and E/(e'×s') ratios (HR=8.17, P=0.
