Multimodal Imaging Unmasks Occult Acute Anterior Myocardial Infarction After Blunt Chest Trauma in a Young Male Patient.

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
backgroundBlunt chest trauma is rarely associated with acute plaque rupture and myocardial infarction in young patients without cardiovascular risk factors. CASE SUMMARY: A 36-year-old man developed severe substernal chest pain immediately after blunt anterior chest trauma while surfing. High-sensitivity troponin I rose rapidly (197-5,700 ng/L over 6 hours). Computed tomography angiography performed to exclude pulmonary embolism showed left ventricular hypoperfusion and a proximal left anterior descending artery filling defect. Echocardiography confirmed an ejection fraction of 40% to 45% with regional wall motion abnormalities. Emergent catheterization revealed 100% thrombotic occlusion of the proximal-to-mid left anterior descending artery due to plaque rupture. Aspiration thrombectomy and drug-eluting stent placement restored TIMI flow grade 3. DISCUSSION: This case illustrates how multimodal imaging rapidly unmasks occult acute anterior myocardial infarction when initial clinical and electrocardiographic findings are equivocal in the trauma setting. TAKE-HOME MESSAGES: A low threshold for advanced imaging and serial high-sensitivity troponin monitoring should be maintained in trauma-related chest pain regardless of age or risk factors. Multimodal imaging enables timely reperfusion and excellent outcomes in occult acute myocardial infarction.
