Atypical Presentation of Acute Myocardial Infarction As Syncope and Abdominal Pain in the Absence of Chest Pain or Discomfort.

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
Atypical presentations of acute myocardial infarction can make early diagnosis challenging, particularly when chest pain or discomfort is absent. We present a case of a 60-year-old man with diabetes, hypertension, a previous myocardial infarction (MI), and heart failure with reduced ejection fraction who presented with syncope and severe abdominal pain but no chest pain or discomfort. The ECG demonstrated an inferior ST-segment elevation myocardial infarction. He received dual antiplatelet therapy and anticoagulation before emergent transfer for coronary angiography, which revealed right coronary artery occlusion. We concluded that acute myocardial infarction can present without chest pain or discomfort and instead manifest with syncope and/or abdominal pain, especially in patients with risk factors for atypical presentations. Clinicians should maintain a high index of suspicion for acute coronary syndrome in such cases to avoid delays in diagnosis and reperfusion therapy, as delays may increase morbidity and mortality.
