Case Report: Rapid progression of inflammation-driven coronary artery lesions in a normolipidemic patient with ANCA-associated vasculitis complicated by Stanford type A aortic dissection.

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
Background: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a systemic autoimmune small- to medium-vessel vasculitis. Reports of rapidly progressive left main/left anterior descending (LM/LAD) disease under normolipidemic conditions with parallel coronary-aortic progression are scarce. Case presentation: We report a case of perinuclear antineutrophil cytoplasmic antibody (p-ANCA) and myeloperoxidase (MPO)-positive ANCA-associated vasculitis (AAV) in which, despite persistently normal lipid levels, the coronary arteries developed rapidly progressive stenosis and occlusion within one year. Intravascular ultrasound (IVUS) revealed concentric thickening of the coronary arterial wall characterized predominantly by soft plaques with minimal calcification, which was consistent with an inflammation-driven remodeling phenotype. Because the admission electrocardiogram (ECG) revealed an ST-segment elevation myocardial infarction (STEMI)-equivalent pattern (aVR ST elevation with diffuse ST depression), the patient was treated for acute myocardial infarction, and urgent LM-to-LAD drug-eluting stent (DES) implantation was performed. During a four-month follow-up after discharge, no recurrent angina or ischemic events were reported. Conclusion: In a p-ANCA/MPO-positive AAV patient with sustained normolipidemia, we observed rapidly progressive LM/LAD disease occurring in parallel with aortic involvement, which was consistent with an inflammation-driven coronary phenotype that precipitated acute coronary syndrome. Integrating sequential coronary-aortic imaging with inflammatory biomarker surveillance and individualized immunomodulatory and antithrombotic strategies may enable earlier risk detection and optimize outcomes in patients with AAV.
