Cardiac Fibroblastoma Presenting as NSTEMI.
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
backgroundMyocardial infarction with nonobstructive coronary arteries (MINOCA) represents ∼8% of acute myocardial infarctions, with causes including myocarditis, coronary spasm, and embolization from cardiac tumors. CASE SUMMARY: A 59-year-old woman presented with exertional chest pain and elevated troponins, consistent with non-ST-segment elevation myocardial infarction. Coronary angiography showed normal coronaries. Cardiac magnetic resonance imaging revealed a small ischemic infarct, prompting review of prior computed tomography, which identified a small aortic valve mass. Transesophageal echocardiography confirmed a mobile lesion. Surgical excision revealed a benign fibroblastoma, an extremely rare cardiac tumor.
conclusionsThis case highlights the importance of thorough imaging review in MINOCA and expands the spectrum of cardiac tumors implicated in coronary embolization. This is to our knowledge one of the first reports of a cardiac fibroblastoma.
