Inferior STEMI in a Patient With Cardiac Metastasis: A Diagnostic Challenge.
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
backgroundCardiac metastases occur more commonly than primary cardiac tumors but are often clinically silent. ST-segment elevation mimicking acute myocardial infarction because of cardiac metastasis is rare. CASE SUMMARY: We present the case of an 80-year-old woman with advanced pulmonary squamous cell carcinoma and intracardiac metastasis presenting with ST-segment elevations on electrocardiogram. Coronary angiography demonstrated nonobstructive coronary disease. Presentation was thought to be secondary to myocardial infiltration leading to myocyte necrosis. Management focused on symptom control, and the patient ultimately transitioned to hospice care and passed away. DISCUSSION: Cardiac metastases can cause ischemic electrocardiographic changes via myocardial invasion, coronary artery compression, or embolization. This case highlights a rare mimic of ST-segment elevation myocardial infarction. TAKE-HOME MESSAGES: Cardiac metastases should be considered in cancer patients with findings of ST-segment elevation and nonobstructive coronary disease. Early recognition can guide prognosis, avoid futile interventions, and support timely goals of care discussions.
