Acute Myocardial Infarction Secondary to Idiopathic Ascending Aortic Thrombus.

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
backgroundAscending aortic thrombus causing acute myocardial infarction through coronary ostial occlusion is exceptional, with only 74 cases reported globally, and may mimic acute aortic dissection on imaging. CASE SUMMARY: A 48-year-old man with no prior history presented with ST-elevation myocardial infarction. Coronary angiography showed near-total right coronary artery ostial occlusion with a right sinus of Valsalva lesion. Echocardiography revealed a mobile aortic root mass. Computed tomography angiography raised concern for Type A dissection. Emergency surgery revealed a 4 × 2-cm organized thrombus with no dissection. Thrombectomy and saphenous vein bypass were performed. Histopathology confirmed organized thrombus; cultures and thrombophilia workup were negative. Discharged on dual-antiplatelet therapy. DISCUSSION: Idiopathic aortic sinus thrombus can mimic acute aortic syndrome while causing coronary ischemia, potentially as a chronic process with acute decompensation. Surgical excision with revascularization is definitive. TAKE-HOME MESSAGES: Aortic root thrombus must be included in the differential of unexplained coronary ostial occlusion in young patients. Emergent surgical exploration enables simultaneous diagnosis and treatment.
