The Great Mimicker: A Unique Case of Diffuse Subarachnoid Haemorrhage Simulating Acute Myocardial Infarction.
Article in European journal of case reports in internal medicine, 2024. 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
Subarachnoid haemorrhage (SAH) is a rare yet consequential medical emergency that may mimic an acute myocardial infarction (MI). SAH causes enhanced sympathetic activity, culminating in the development of neurogenic stunned myocardium (NSM), which presents as ST-segment deviations, prolonged QT intervals, T-wave inversions or Q-waves. Reperfusion therapy is contraindicated for SAH because of an increased risk of bleeding and death. Therefore, a prompt diagnosis is crucial. Here, we report a unique case of massive SAH presenting as diffuse ST-segment deviation simulating an acute MI. Our patient was brought to the emergency department after a cardiac arrest and died on day 2 of admission. LEARNING POINTS: Subarachnoid haemorrhage (SAH) can present with EKG changes and significant rise in troponin, mimicking acute coronary syndrome.SAH should be included in the differential diagnosis for patients presenting with neurological symptoms, ST-segment deviations or prolonged QT intervals.Misdiagnosis of SAH as acute coronary syndrome can lead to inappropriate use of anticoagulants or delays in necessary neurological interventions.
