“… 23 Previous studies demonstrated the usefulness of the E/(e’xs’) ratio to predict new-onset AF and AF recurrence after ECV. 8 , 10 Univariate and multivariate analysis of our data showed that the E/(e’xs’) ratio was a significant predictor of early AF recurrence after ECV and demonstrated higher hazard ratios than E/e’ ratio. ROC analysis revealed that AUCs of E/(e’xs’) and E/e′ ratios were similar: AUC=0.71 and AUC=0.75, respectively.…”

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.

“…[ 7 ] In addition, this parameter resulted useful also in predicting new-onset atrial fibrillation in patients with HF, in sinus rhythm, regardless of EF, and it was the strongest predictor of new-onset AF compared to several other echocardiographic parameters (conventional and TDI parameters), clinical variables, and plasmatic N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) levels. [ 15 ] Recently, the prognostic value of E/(E' × S') average was demonstrated in patients with HF with preserved and reduced EF: the dimensionless index was the only independent predictor of future cardiovascular events (cardiovascular death, nonfatal myocardial infarction, and HF exacerbation) in both HF populations. [ 16 ] According to the theory of the continuous cycle, the present study demonstrates that E/(E' × S') average has a significant prognostic impact also in a population of asymptomatic HF patients.…”

Introduction:Doppler echocardiography with early diastolic transmitral velocity (E)/early mitral annular diastolic velocity (E') ratio has been proposed as the best predictor for evaluating left ventricle (LV) filling pressure. A dimensionless index E/(E' × S') ratio (S' = systolic mitral annulus velocity) resulted in readily, reproducible, and reliable predictor of LV filling pressure. We assessed the prognostic impact of E/E' × S') in patients with asymptomatic heart failure (HF).Materials and Methods:We calculated E/(E' × S') in 337 patients (179 male, 53%; age 54.7 ± 13.7 years) using the average of septal and lateral mitral annular velocities. We considered a composite endpoint as follows: all-cause death, acute myocardial infarction, stroke, and HF exacerbation.Results:Baseline ejection fraction resulted 60.2 ± 11.8%; E/E' × S') was 1.45 ± 0.8, with S' 7.4 ± 2.4 cm/s and E/E' 9.5 ± 5.4. After a 22-month median follow-up, there were 42 events: 5 deaths (12%), 3 acute myocardial infarctions (7%), 1 stroke (2%), and 33 HF hospitalizations (79%). In patients reaching the composite endpoint, E/(E' × S') resulted 2.07 ± 1.1 versus 1.3 ± 0.7 in event-free population (P < 0.001). In a Cox-regression analysis, adjusted for confounding clinical factors and conventional echo parameters, E/(E' × S') (P < 0.001), age (P < 0.001), and male gender (P = 0.03) resulted independent predictors of the composite endpoint.Conclusions:E/(E' × S') was an independent predictor for the future cardiac events in asymptomatic HF.
