Myocardial Infarction With PFO: Distinguishing SCAD From Coronary Embolism.
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 in young patients without traditional cardiovascular risk factors raises concern for nonatherosclerotic etiologies such as spontaneous coronary artery dissection and coronary embolism. CASE SUMMARY: A 38-year-old woman with no past medical history presented with acute substernal chest pain associated with nausea and vomiting. Evaluation was consistent with non-ST-segment elevation myocardial infarction (NSTEMI), with dynamic elevation in high-sensitivity troponin levels and ischemic electrocardiographic changes. Transthoracic echocardiography demonstrated mildly reduced left ventricular systolic function with regional wall motion abnormalities not confined to a single coronary distribution as well as a large right-to-left interatrial shunt with atrial septal aneurysm. Coronary angiography identified focal occlusion of a septal perforator branch of the left anterior descending artery. She was managed with guideline-directed NSTEMI therapy and later underwent outpatient patent foramen ovale closure. DISCUSSION: This case illustrates the diagnostic complexity of NSTEMI in young patients when angiographic findings and cardiac imaging suggesting nonatherosclerotic etiologies. TAKE-HOME MESSAGE: NSTEMI in young patients warrants standard acute coronary syndrome management while concurrently evaluating for alternative mechanisms of myocardial injury.
