Multifactorial Hypercoagulability Causing Simultaneous STEMI and Pulmonary Embolism in Young Adults With Prothrombin G20210A Mutation.
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
backgroundThe simultaneous occurrence of ST-segment elevation myocardial infarction and pulmonary embolism is rare, especially in young individuals without known cardiovascular disease. Both presentations imply an underlying hypercoagulable state or paradoxical embolism. CASE SUMMARY: A 27-year-old man experienced cardiac arrest during exercise and was diagnosed with both ST-segment elevation myocardial infarction and pulmonary embolism. Tests revealed thrombotic occlusion of the left posterior descending artery, lower extremity deep venous thrombosis, pulmonary arteriovenous malformation, and heterozygous prothrombin gene mutation. He was treated with mechanical thrombectomy and anticoagulation. DISCUSSION: This case demonstrates simultaneous arterial and venous thrombosis, likely from inherited hypercoagulability amplified by dehydration, alcohol, tobacco, and trauma, though paradoxical embolism cannot be entirely excluded. TAKE-HOME MESSAGE: Comprehensive thrombophilia evaluation and systemic shunt exclusion are essential in young patients with concurrent arterial and venous thrombosis.
