ST-Segment Elevation Myocardial Infarction From Carney Complex Familial Myxoma Embolization.
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
backgroundCarney complex (CNC) is a rare condition associated with multiorgan system tumors. Cardiac myxomas are a frequent complication of this disease. CASE SUMMARY: A 20-year old man with CNC presented with 3 days of dyspnea. Echocardiography revealed a rapidly growing left atrial myxoma. He developed chest pain (score: 10/10) during his hospitalization and was found to have an acute inferior ST-segment elevation myocardial infarction (STEMI). Emergent percutaneous balloon angioplasty and aspiration thrombectomy were performed, with eventual surgical myxoma excision. DISCUSSION: STEMI due to myxoma embolization is rare and poorly understood. This case highlights the pathophysiology and complications associated with CNC, the acute therapeutic interventions for STEMI from myxoma embolization, and the long-term management of atrial myxomas. TAKE-HOME MESSAGES: In young patients with CNC, STEMI is often embolic from cardiac myxomas; acute treatment typically involves percutaneous coronary intervention with thrombectomy rather than stent placement. Definitive treatment involves surgical excision of the myxoma using a multidisciplinary approach, although recurrence rates are high in CNC.
