ST-elevation in aVR with Diffuse ST-segment Depression: Need for Urgent Catheterization?
Article in Clinical practice and cases in emergency medicine, 2025. 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 presentationA 33-year-old female with a history of antiphospholipid syndrome presented with exertional chest pain and ST-elevation in aVR with diffuse ST-segment depression. An emergent catheterization was performed, which showed an isolated 99% stenosis in the left main coronary artery. The remaining coronary arteries were without any stenosis. Successful stent placement was performed, and the patient was discharged without complications. DISCUSSION: Previous guidelines have suggested that ST-segment elevation with diffuse ST-segment depression should be treated as a ST-elevation myocardial infarction equivalent involving either the left-main or proximal left anterior descending coronary artery. However, recent data suggests that most of these cases may not involve that region. Regardless, this electrocardiogram finding should still be a concern for acute coronary syndrome, with the need for urgent catheterization.
