The Prognostic-Diagnostic paradox of lead aVR: From 'STEMI-Equivalent' to 'High-Risk NOMI' in the era of precision cardiology.
Review in International journal of cardiology. Heart & vasculature, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The electrocardiographic pattern of ST-segment elevation in lead aVR (STE-aVR) coupled with diffuse ST-segment depression is a finding of profound clinical gravity. Historically termed a "STEMI equivalent" suggestive of acute left main coronary artery occlusion, this designation has driven decades of aggressive reperfusion strategies. However, contemporary angiographic data reveals a stark "Prognostic-Diagnostic Paradox": while the pattern predicts high mortality and severe anatomical disease, it poorly predicts acute thrombotic occlusion. This monograph provides an exhaustive evaluation of the electrophysiological mechanisms, clinical evidence, and evolving guidelines surrounding lead aVR. Integrating landmark studies from 2013 to 2019 with novel 2025 concepts such as "Northern OMI" and the "Precordial Swirl," we propose a modernized, physiology-based clinical algorithm. This framework reclassifies the pattern for hemodynamically stable patients from a trigger for immediate catheterization to a marker of high-risk Non-Occlusive Myocardial Infarction (NOMI), necessitating distinct management to avoid iatrogenic harm from mimics while ensuring timely intervention for true ischemia.
