Apical Hypertrophic Cardiomyopathy (Yamaguchi Syndrome) Presenting as Acute Coronary Syndrome Mimic: 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
Apical hypertrophic cardiomyopathy (ApHCM), or Yamaguchi syndrome, is a morphological variant of hypertrophic cardiomyopathy that frequently mimics acute coronary syndrome (ACS) due to ischemic-type chest pain and characteristic electrocardiographic changes. A 46-year-old woman presented with angina and deep T-wave inversion in precordial leads. Coronary angiography showed normal epicardial arteries. Transthoracic echocardiography revealed localized left ventricular apical hypertrophy with preserved systolic function and the typical "ace-of-spades" cavity configuration, confirming ApHCM. She was managed conservatively with beta-blockers and guideline-directed therapy, with symptomatic improvement. Early recognition prevents unnecessary invasive procedures and facilitates appropriate long-term management.
