Characterization of anticancer therapy-induced microvascular dysfunction in patients with breast cancer supports targeted intervention.
Article in JCI insight, 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
BACKGROUNDCardiotoxicity is a major complication of anticancer therapy (CTx); however, the effect of CTx on the microcirculation is not well defined. This study evaluated the effect of CTx on microvascular function in patients with breast cancer (PwBC).METHODSEndothelial function and angiogenic potential were assessed in arterioles and adipose biopsies obtained from PwBC undergoing CTx (longitudinal and cross-sectional) and in healthy arterioles exposed to doxorubicin (Dox), trastuzumab (TZM), or paclitaxel (PTX) ex vivo. VEGF-B protein was used to test feasibility of targeted intervention.RESULTSPwBC treated with Dox and/or TZM developed profound microvascular endothelial dysfunction that persisted for ≥ 9 months after treatment cessation. Angiogenic potential was reduced during CTx and recovered within 1 month. Gene expression related to angiogenesis and inflammation changed over the course of clinical treatment. Adipose arterioles from healthy donors developed endothelial dysfunction when exposed to Dox or TZM ex vivo. PTX, which poses minimal cardiovascular risk, had no effect on vasomotor function. Ex vivo exposure to Dox or PTX suppressed angiogenic potential, whereas TZM had no effect. VEGF-B protein preserved endothelial function in arterioles exposed to Dox or TZM ex vivo.CONCLUSIONPwBC undergoing treatment with Dox and/or TZM develop prolonged microvascular endothelial dysfunction that is recapitulated in healthy arterioles exposed to Dox or TZM ex vivo. Targeted intervention with VEGF-B protects against direct Dox- or TZM-induced vascular toxicity in human arterioles ex vivo.FUNDINGNIH, American Heart Association, WeCare Foundation, Medical College of Wisconsin, Advancing a Healthier Wisconsin, Jenny and Antti Wihuri Foundation.
