Clinical utility of single-beat E/e' obtained by simultaneous recording of flow and tissue Doppler velocities in atrial fibrillation with preserved systolic function
Open accessAbstract
Objectives We evaluated the usefulness of the ratio of the early diastolic transmitral flow velocity (E) to the mitral annular velocity (e') calculated from simultaneously recorded E and e' in atrial fibrillation (AF).Background The ratio of the E to the e' (E/e') has been reported as a useful index even in AF patients. However, E and e' were measured during different beats in the previous studies.Methods Fifty-six AF patients with preserved systolic function (mean age 66 +/- 11 years) underwent routine echocardiographic study. The E/e' was calculated from the E and e' simultaneously recorded by the dual Doppler echocardiography. A single-beat E/e' was calculated from simultaneously recorded E and e' when the preceding RR interval/pre-preceding RR interval = 1. Brain natriuretic peptide (BNP) levels were also examined. Twenty-one patients underwent simultaneous pulmonary artery catheterization.Results The single-beat lateral E/e' correlated with pulmonary capillary wedge pressure (PCWP) (r = 0.74, p < 0.001). The single-beat lateral E/e' of >or=11 could predict elevated PCWP (>or=15 mm Hg) with a sensitivity of 90% and a specificity of 90%. The single-beat lateral E/e' also correlated well with the log BNP concentration. The single-beat lateral E/e' of >or=9.2 predicted a plasma BNP level of >or=200 pg/ml with 88% sensitivity and 84% specificity.Conclusions The single-beat lateral E/e' correlated with plasma BNP level and PCWP in AF patients with preserved systolic function. In addition, the single-beat lateral E/e' (>or=11) was a good predictor of elevated PCWP (>or=15 mm Hg). Dual Doppler echocardiography offers an advantage of providing the single-beat lateral E/e' correctly even in AF patients, for the evaluation of left ventricular diastolic function.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
