Pseudo-Wellens Syndrome Caused by Myocardial Bridging.
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
backgroundWellens syndrome is a preinfarction electrocardiographic pattern classically associated with critical proximal left anterior descending artery stenosis. However, nonatherosclerotic conditions, including myocardial bridging, may mimic this pattern. CASE SUMMARY: A 58-year-old man presented with intermittent chest pain and Wellens T-wave changes in the anterior leads. High-sensitivity troponin T levels were normal. Coronary angiography revealed normal coronary arteries with a mid left anterior descending myocardial bridge and no fixed stenosis. Beta-blocker therapy was deferred owing to baseline bradycardia. DISCUSSION: Myocardial bridging may produce a pseudo-Wellens pattern through dynamic systolic compression and transient ischemia. TAKE-HOME MESSAGE: Recognition of this phenocopy is essential to avoid misdiagnosis and unnecessary intervention.
