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

backgroundAlthough rapid recovery of cardiac contraction is a hallmark of Takotsubo cardiomyopathy (TTC), the time course of recovery is still ill-defined. We aimed to investigate the time course of left ventricular (LV) functional recovery using 2D speckle tracking echocardiography and electrocardiography (ECG).

methodsThirty-two consecutive patients (65 ± 16 years, 26 women) with TTC were prospectively recruited. ECG and echocardiography were performed at baseline (No. 1), before discharge (No. 2), and at 1 week (No. 3) and 5 weeks (No. 4) after discharge. Echocardiographic images and ECGs were analyzed to measure ejection fraction (LVEF), global and regional longitudinal strain (GLS, RLS), and T wave inversion (TWI) scores.

resultsAt baseline, LVEF, GLS, and TWI score were 39 ± 8.8%, -11 ± 4.3%, and 1.8 ± 3.0, respectively. Both LVEF and GLS continued to improve from baseline at the No. 2, No. 3, and No. 4 timepoints (49 ± 9.3%, 56 ± 7.5%, 58 ± 6.8%, respectively, for LVEF and -15 ± 4.2%, -17 ± 3.9%, -19 ± 3.4%, respectively, for GLS). TWI score was decreased at the No. 3 ECG relative to baseline and then increased (No. 2: -2.5 ± 3.0, No. 3: -2.9 ± 5.2, No. 4: -0.3 ± 4.4). In the apical subgroup, the reverse base-to-apex gradient of RLS had disappeared by the No. 3 echocardiography.

conclusionsContractile function as assessed by LVEF and GLS recovered continuously in patients with TTC throughout the acute and subacute phases, with rapid recovery in the acute phase. Negative T wave progressed during the acute phase and recovered more slowly during the subacute phase.
