Focal Takotsubo Syndrome Mimicking a Distal Coronary Pathology: A Case Report.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 syndrome (TTS) is a transient stress-induced cardiomyopathy. It typically occurs following emotional or physical stressors. Many variants are described, the most common being the apical ballooning; however, atypical variants such as focal TTS are rare and can mimic acute coronary syndromes. We report the case of a 49-year-old woman presenting with chest pain and marked troponin elevation who underwent coronary angiography with left ventriculography demonstrating non-obstructive coronary arteries, inferior apical hypokinesis, and a subtle distal left anterior descending artery abnormality. Serial troponin testing confirmed a peak high-sensitivity troponin of 1,967 ng/L. In the context of emotional stress, absence of obstructive coronary disease, and atypical angiographic features inconsistent with plaque rupture or spontaneous coronary artery dissection, a diagnosis of focal TTS was considered most consistent. This case highlights the diagnostic challenges in identifying focal variants of Takotsubo cardiomyopathy.
