Environmental Toxic Metals and Metalloids Exposure and Cardiovascular Health: Current Evidence from Oxidative Stress and Inflammatory Biomarkers as Indicators of Subclinical Cardiovascular Effects.
Review in Antioxidants (Basel, Switzerland), 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
Cardiovascular diseases remain the leading cause of global mortality, and environmental toxic metals and metalloids (TMMs) exposure has emerged as an important and potentially modifiable cardiovascular (CV) risk factor. Due to their persistence, bioaccumulation, and widespread distribution, represent a significant public health concern and have been associated with adverse CV outcomes. Mechanistically, TMM-induced cardiotoxicity is primarily mediated through oxidative stress (OS) and inflammatory pathways. Accordingly, related biomarkers, may be considered markers of biological effect and potential pathophysiological mediators associated with TMM exposure. This narrative review summarizes epidemiological evidence linking environmental TMMs exposure with OS and inflammatory biomarkers to CV outcomes. A structured literature search identified 1915 records in PubMed, of which 42 epidemiological studies met the inclusion criteria. The reviewed evidence consistently indicates that environmental and occupational TMMs exposure is associated with significant alterations in biomarkers of lipid peroxidation, antioxidant defense, systemic inflammation, and endothelial dysfunction, all of which reflect early biological CV effects associated with exposure. However, substantial heterogeneity across studies and the predominance of cross-sectional designs limit causal inference and the evaluation of their predictive capacity for future CV events. Future prospective studies integrating mixture-based exposure assessment, standardized biomarker measurements, and multi-omics approaches are needed to clarify whether these biomarkers can serve as markers of biological effect or subclinical CV toxicity and as potential mediators of CV risk, while also assessing their potential contribution to cardiovascular risk stratification in exposed populations.
