Elastic recoil signal on tissue doppler imaging of mitral annulus as a qualitative test to identify left ventricular diastolic function.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Left ventricular (LV) diastolic dysfunction is common on preoperative screening among patients undergoing surgery. There is no simple screening test at present to suspect LV diastolic dysfunction. This study was aimed to test the hypothesis, whether elastic recoil signal (ERS) on tissue Doppler imaging of mitral annulus (MA TDI) can be used as a qualitative test to differentiate patients from normal LV diastolic function versus patients with LV diastolic dysfunction. Methods: This was a prospective cross-sectional observational study of patients admitted for elective surgeries. Normal diastolic function and categorization of LV diastolic dysfunction into severity grades I, II, or III were performed as per the American Society of Echocardiography/ European Associationof Cardio Vascular Imaging (ASE/EACVI) recommendations for LV diastolic dysfunction. Results: There were 41 (61%) patients with normal LV diastolic function and 26 (39%) patients with various grades of LV diastolic dysfunction. In 38 out of 41 patients with normal LV diastolic function, the characteristic ERS was identified. The ERS was absent in all the patients with any grade of LV diastolic dysfunction. Consistency of identification of ERS on echocardiography was tested with a good interobserver variability coefficient of 0.94 (P-value <0.001). The presence of ERS demonstrated an excellent differentiation to rule out any LV diastolic dysfunction with an area under the receiver operating characteristics curve (AUROC) of 0.96 (CI 0.88-0.99; P value <0.001). Conclusions: To conclude, in a mixed surgical population, the anesthetist could successfully assess LV diastolic dysfunction in the preoperative period and the characteristic ERS on MA TDI signal can be used as a qualitative test to differentiate patients from normal LV diastolic function versus patients with LV diastolic dysfunction using the transthoracic echocardiography (TTE).
