Coronary Artery Anomaly in Takotsubo Cardiomyopathy: Cause or Innocent Bystander?
Article in Texas Heart Institute journal, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Coronary artery anomalies can provoke intermittent vasospasm and endothelial dysfunction, which can cause takotsubo cardiomyopathy. However, in takotsubo cardiomyopathy, apical myocardial regions are typically affected, and these do not correlate with a specific epicardial coronary distribution territory. We report the case of a 74-year-old woman who presented with acute respiratory failure and suspected myocardial infarction. She had a left coronary artery anomaly, dominant right coronary artery supply, takotsubo cardiomyopathy, depressed left ventricular ejection fraction, and no atherosclerotic disease. In the absence of exercise ischemia, we considered the anomalous artery to be an incidental finding. After 6 weeks of medical therapy, the patient's ejection fraction was normal; one year later, she remained asymptomatic. The anomalous left coronary artery in the presence of dominant right coronary supply did not explain the diffuse apical regional wall-motion abnormalities in our patient. To our knowledge, this is the first report of coexisting takotsubo cardiomyopathy and anomalous coronary artery in a patient presenting with acute dyspnea.
