Post-Anaphylaxis Adrenaline-Induced Takotsubo Cardiomyopathy: 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. Cited by 1 paper.
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) is an acute and reversible cardiac condition triggered by an adrenaline rush in response to stress that is characterised by apical ballooning of the left ventricle in the absence of coronary artery obstruction. Although the exact pathophysiology remains unclear, it is believed to be secondary to the release of adrenaline or catecholamine in response to stress. We present the case of a 71-year-old female who presented to a district general hospital (DGH) at approximately 1700 pm in the evening with signs and symptoms of anaphylaxis following the consumption of pistachios the night before. She woke up with mild shortness of breath (sob) in the morning at 0900 am. The symptoms progressively got worse after midday, and she developed throat tightness and mild tongue swelling at 1600, prompting her to attend the local hospital's accident and emergency department. Following evaluation in the accident and emergency department, she was given 0.5 mg of adrenaline one in 1000 (1 mg/mL) solution intramuscularly for a delayed allergic reaction to pistachios. She developed central chest pain and tightness within minutes of receiving the intramuscular adrenaline, and an electrocardiogram showed ST elevation in the lateral leads and ST depression inferiorly. She was transferred to our cardiac centre for emergency coronary angiography, and bedside echocardiography revealed mild to moderate left ventricular systolic dysfunction (LVSD). Coronary angiography via the right radial access showed unobstructed coronaries. Left ventriculogram (LVG) post-angiogram demonstrated apical ballooning suggestive of TCM secondary to adrenaline administration for anaphylaxis to pistachio. Departmental echocardiography revealed a mild LVSD with an ejection fraction of 45%. She was started on bisoprolol in addition to her regular medications. Echocardiography demonstrated normal left ventricular function three months later, and the patient was discharged from the outpatient clinic.
