ST-Segment Elevation in a Patient With Vocal Cord Cancer: A Great Mimicker.
Article in JACC. Case reports, 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
case summaryCardiac metastasis mimicking ST-segment elevation myocardial infarction is a rare "pseudoinfarction pattern." A 58-year-old man with recurrent laryngeal carcinoma presented with pleuritic chest pain and anterolateral ST-segment elevation. High-sensitivity troponin levels plateaued (70-76 ng/L). Emergent coronary angiography was deferred due to the pain's quality, the absence of dynamic electrocardiogram evolution, and bedside echocardiographic identification of a right ventricular mass. Positron emission tomography-computed tomography confirmed extensive neoplastic infiltration. This pattern results from a persistent injury current at the tumor-myocardium interface. Recognition is vital to avoid futile invasive procedures and guide appropriate palliative systemic therapy. TAKE-HOME MESSAGES: Persistent ST-segment elevation in an oncology patient without typical dynamic evolution should raise suspicion of myocardial tumor infiltration. Multimodality imaging, particularly emergent bedside echocardiography, is essential to differentiate malignant "injury currents" from acute coronary syndromes and avoid unnecessary invasive interventions.
