The Shape-Shifting Heart: Recurrent Takotsubo Cardiomyopathy Manifesting as Two Variants in One Patient.

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
Takotsubo cardiomyopathy (TCM), also known as stress-induced cardiomyopathy, is a transient left ventricular dysfunction that mimics acute coronary syndrome but typically resolves within weeks. Its recurrence is uncommon, and recurrence with distinct morphologic variants is exceedingly rare. We report a 75-year-old female with peripheral arterial disease, paroxysmal atrial fibrillation, sick sinus syndrome status post pacemaker, and prior apical variant TCM in 2022. She underwent a right lower extremity surgery. Two days postoperatively, she developed acute chest pain and troponin elevation. Echocardiography revealed new left ventricular dysfunction with an ejection fraction (EF) of 35-40% and hypokinesis of the anteroseptal and anterior walls. Coronary angiography demonstrated mild nonobstructive coronary artery disease (CAD). Ventriculography confirmed the mid-ventricular variant of TCM. This contrasted with her prior episode in 2022, when she developed apical ballooning variant TCM with an EF of 25-30% during admission for
