Cardiac Metastasis Mimicking Lateral STEMI in Small-Cell Lung Cancer.
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
backgroundST-segment elevation in patients with cancer may reflect malignant myocardial-pericardial infiltration rather than acute coronary occlusion. CASE SUMMARY: A 68-year-old man with active small-cell lung carcinoma receiving chemotherapy presented with acute stabbing chest pain. Electrocardiography showed ST-segment elevation in leads I, aVL, and V2 with inferior reciprocal depression. Transthoracic echocardiography demonstrated anterolateral hypokinesia, focal myocardial discontinuity, and adjacent pericardial effusion. Emergent coronary angiography revealed nonobstructive coronary arteries, and initial high-sensitivity troponin values were nondynamic. Review of recent fluorodeoxyglucose positron emission tomography/computed tomography demonstrated intense hypermetabolic pericardial and adjacent myocardial involvement. One-month follow-up electrocardiography showed persistent ST-segment elevation without Q-wave evolution, with persistently mildly elevated but nondynamic troponin values. DISCUSSION: Multimodality correlation favored malignant myocardial-pericardial infiltration over acute coronary occlusion or isolated myocarditis. TAKE-HOME MESSAGE: Cardiac metastasis is an important ST-segment elevation myocardial infarction mimic in oncology patients.
