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

Takotsubo cardiomyopathy (TCM) leads to serious left ventricular outflow tract (LVOT) obstruction with cardiogenic shock in 6%-20% of cases. The onset of LVOT obstruction, coupled with mitral regurgitation resulting from systolic anterior motion of mitral valve leaflets, can lead to haemodynamic instability in addition to severely impaired systolic function. We describe three patients who experienced chest discomfort following emotional stress. These patients displayed pronounced abnormalities on ECGs, insignificant obstructive coronary disease and haemodynamic instability due to LVOT obstruction. The infusion of landiolol, a short-acting beta blocker, was effective in releasing the gradient. Dynamic outflow obstruction is the major predictor of haemodynamic collapse. We suggested that an early identification of this complication in hypotensive patients with suspected TCM could be of utmost importance to optimise the therapeutic approach in the acute setting.
