Takotsubo Cardiomyopathy Complicated by High-Grade Atrioventricular Block in a Patient With Preexisting Conduction Disease: A Case Report.
Article in Cureus, 2025. 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 cardiomyopathy (TTC) often mimics acute coronary syndrome, presenting with chest pain, electrocardiogram (ECG) changes, and troponin rise. While usually reversible, it can rarely be complicated by conduction abnormalities such as high-grade atrioventricular (AV) block. We report a 79-year-old woman with poorly controlled hypertension and preexisting trifascicular block who presented with chest pain precipitated by extreme emotional stress due to the inability to obtain her antihypertensive tablets prescription via her General Practitioner, coinciding with the anniversary of her husband's death. Initial evaluation based on her 12-lead ECG was in keeping with a lateral ST elevation myocardial infarction, but emergency invasive coronary angiography revealed unobstructed coronaries with classical apical ballooning of the left ventricle. Transthoracic echocardiography (TTE) and cardiac magnetic resonance imaging (MRI) within 48 hours confirmed TTC. Over the following days, she developed Mobitz II AV block progressing to high-grade AV block. Given her persistent poor left ventricular systolic function and high risk of pacing dependency, the consensus opinion after discussion in the multidisciplinary device team meeting opted for a cardiac resynchronisation therapy pacemaker (CRT-P), which was implanted successfully. This case highlights the rare association between TTC and high-grade AV block, particularly in patients with underlying conduction disease. Early recognition and individualised pacing strategies are essential for improving outcomes.
