Wellens' Sign and Syndrome Detected With the Home Use of a Novel 12-Lead Electrocardiogram.
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' sign is a high-risk electrocardiogram (ECG) pattern associated with proximal left anterior descending artery stenoses and high risk of major adverse cardiovascular events. EARLY REPORTS SUMMARY: A man with transient chest pain remained asymptomatic including with exertion for 48 hours. His friend performs a home 12-lead ECG using a novel, artificial intelligence-enabled device that showed a classic Wellens' Sign Type A, and the man went to a hospital and subsequently received 2 stents in his proximal left anterior descending artery. DISCUSSION: The Kardia12L is a Food and Drug Administration-cleared, pocket-sized ECG device that generates an interpreted 12-lead ECG. Devices like Kardia 12L can lead to diagnosis of cardiovascular disease from home and improve outcomes. NOVELTY: This case highlights the utilization of novel technology to facilitate accurate diagnosis. TAKE-HOME MESSAGES: This case illustrates Wellens' Type A Sign and Syndrome in an asymptomatic patient with a history of chest pain. New technology enables the recording of a diagnostic ECG in high-risk patients anywhere.
