Takayasu Arteritis Presenting With Cardiac Arrest: An Intravascular Imaging Triggered Diagnosis.
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
backgroundAcute coronary syndromes in young patients with minimal risk factors pose diagnostic dilemmas. We report a rare case of myocardial infarction and cardiac arrest caused by Takayasu arteritis. CASE SUMMARY: A 44-year-old Caucasian woman presented with chest pain, syncope, and ventricular tachycardia. Electrocardiogram showed global ischemia with ST-segment elevation in lead aVR. Coronary angiography revealed severe ostial left main coronary artery stenosis with intravascular ultrasound excluding atherosclerosis or dissection. Computed tomography angiography suggested large vessel vasculitis, and positron emission tomography excluded active inflammation. Through multidisciplinary input, a diagnosis of inactive "burnt-out" Takayasu arteritis was made. The patient underwent percutaneous coronary intervention and was managed without immunosuppression. DISCUSSION: Takayasu arteritis is a rare cause of coronary ischemia in adults. Coronary ostial stenoses without atherosclerosis or dissection on intravascular imaging should raise suspicion. A multidisciplinary approach alongside multimodal imaging improves outcomes. TAKE-HOME MESSAGE: This case highlights a rare cause of acute coronary syndrome in a young patient, the usefulness of coronary intravascular imaging when presented with discordant clinical and coronary angiographic findings, and the value of multimodality imaging and the multidisciplinary team.
