Cardamonin attenuates angiotensin II-induced abdominal aortic aneurysms through activation of the Nrf2/HO-1 pathway.
Article in International journal of cardiology. Heart & vasculature, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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: Cardamonin is a natural chalcone compound. It has been shown to have various pharmacological properties. Cardamonin can activate the Nrf2 signaling pathway. Abdominal aortic aneurysm (AAA) is a complex degenerative aortic disease. Ruptured AAAs continue to be among the leading causes of sudden death in elderly individuals. No medical therapy has proven clinical benefits for preventing AAA progression. Therefore, an adjunctive medical therapy is essential to address this unmet clinical need. Methods: Human aortic smooth muscle cells (HASMCs) were used to determine the molecular mechanism of cardamonin. A murine model of angiotensin II (AngII)-induced AAA was used to assess the therapeutic effects of cardamonin on AAA growth in apolipoprotein E knockout (ApoE KO) mice Results: Cardamonin induced Nrf2 translocation from the cytosol to the nuclear compartment in HASMCs. Cardamonin reduced AngII-induced ROS production and matrix metalloproteinases (MMPs) overexpression through activation of the Nrf2/heme oxygenase-1 (HO-1) antioxidant pathway in HASMCs. Silencing HO-1 attenuated the anti-ROS effects of cardamonin and abolished the protective effects of cardamonin in AngII-challenged HASMCs. Cardamonin (20 mg/kg/day) reduced AngII-induced AAA Conclusion: Cardamonin inhibits the progression of AngII-induced AAA through Nrf2/HO-1-mediated antioxidant and anti-inflammatory pathways. Cardamonin could have the potential to be an adjunctive therapy for small AAAs.
