1 · What the graph read from it

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.

2 · The registry

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

backgroundEvaluation of left ventricular function (LV) is one of the most important tasks of echocardiography. Left ventricular longitudinal function has been recognized to differentiate myocardial disorders better than ejection fraction (EF) alone. But recent parameters are still dependent on image quality and time consuming.

methodsTransthoracic echocardiography, tissue Doppler imaging, strain imaging and assessment of longitudinal function with a tissue motion annular displacement (TMAD) tracking algorithm were performed in 152 patients with various cardiac pathologies and 47 healthy volunteers in a clinical routine setting.

resultsMeasures of longitudinal function such as LV peak systolic strain (SR, r² = 0.88, p < 0.001) and peak systolic strain rate (SRR, r² = 0.78, p < 0.001) correlated highly with TMAD. Tissue motion annular displacement was ultrafast and less time-consuming compared to strain imaging (8.2 ± 2.2 s, p < 0.001). Significantly more patients with reduced image quality could be analyzed compared to strain imaging (p < 0.001). The intra- and inter-observer variabilities were very low with 1.3 ± 1% and 1.7 ± 1.2%. Tissue motion annular displacement correlated well with clinical parameters (NYHA, r = -0.71, p < 0.001) as well as NT-proBNP (r = -0.73, p < 0.001) and identified patients with structural heart disease with a significantly higher sensitivity 92.1% and specificity 95.7% than did EF, SR, SRR or NT-proBNP (Cut-off:14.2%, p < 0.01). In a subgroup of patients with systemic light chain amyloidosis and preserved EF (>50%, n = 54), TMAD was significantly reduced, especially in those without any signs of cardiac involvement and was superior to other parameters of longitudinal function (p < 0.05).

conclusionsTissue motion annular displacement is a rapid, sensitive and reproducible method for the assessment of LV longitudinal function, which is less dependent on image quality.
