Alcohol-induced placental vasculopathy reprograms the placental-fetal cardiovascular axis: angiogenic mechanisms linking maternal alcohol exposure to developmental cardiovascular programming.
Review in Frontiers in physiology, 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
Among prenatal insults, maternal alcohol consumption has emerged as an important determinant of fetal cardiovascular development and long-term cardiovascular disease susceptibility. Growing evidence indicates that the placenta is a central biological mediator linking maternal alcohol exposure with abnormal fetal cardiac development. This review integrates current experimental and clinical findings on the developmental relationship between placental vascularization and fetal cardiogenesis, highlighting the placental-embryofetal cardiovascular axis as a conceptual framework for alcohol-induced cardiopathy programming. We examine evidence that prenatal alcohol exposure disrupts placental vascular development through impaired decidual spiral artery angiogenesis and remodeling and altered trophoblast differentiation and invasion, and labyrinthine vascularization. Experimental studies suggest that oxidative stress and hypoxia perturb interconnected angiogenic vascular endothelial growth factor (VEGF)-nitric oxide synthases (NOS)-matrix metalloproteinases (MMPs) pathways, and related redox-sensitive mediators, ultimately compromising placental perfusion and fetoplacental hemodynamics. We further discuss that placental dysfunction may alter the molecular, metabolic, endocrine, oxygen-dependent, and hemodynamic signals regulating fetal cardiac development, potentially affecting myocardial morphogenesis, cardiac remodeling, coronary vascularization, septation, valvulogenesis, and cardiovascular maturation during critical developmental windows. Collectively, available evidence supports a model in which disruption of placental angiogenic homeostasis may represent a key intermediary linking maternal alcohol exposure with fetal cardiovascular programming. This perspective integrates direct embryofetal effects with indirect placental-mediated mechanisms and highlights the need to clarify their relative contributions across developmental windows. Improved understanding of the placental-embryofetal cardiovascular axis may facilitate identification of early biomarkers and preventive or therapeutic strategies to reduce the lifelong cardiovascular consequences of prenatal alcohol exposure.
