A comprehensive systematic review published in 2024 synthesized data from 26 studies to assess the relationship between cadmium exposure and cardiovascular disease (CVD). The review utilized a dose-response meta-analysis approach to examine the association between cadmium levels, measured in urine and whole blood, and various cardiovascular outcomes, including overall CVD, coronary heart disease (CHD), heart failure, and stroke. The findings revealed a consistent positive association between cadmium exposure and increased CVD risk, with risk ratios indicating a significant relationship between higher cadmium levels and adverse cardiovascular events.
Who is affected?
The findings of this review have implications for a broad spectrum of populations. Individuals with elevated cadmium exposure, particularly those residing in areas with high environmental cadmium levels, are at increased risk. Populations with occupational exposure, such as workers in industries involving cadmium-containing materials, are also at heightened risk. Additionally, lifestyle factors, such as smoking, can contribute to higher cadmium levels, further increasing susceptibility to cardiovascular diseases.
Most important findings
The systematic review identified a significant association between cadmium exposure and various cardiovascular outcomes. Specifically, the review reported risk ratios indicating increased risks for overall CVD, CHD, heart failure, and stroke associated with higher cadmium levels. These findings underscore the importance of considering cadmium exposure as a potential risk factor in cardiovascular health assessments. The review also highlighted the need for further research to elucidate the mechanisms underlying this association and to establish definitive exposure thresholds for regulatory purposes.
Key implications
The implications of these findings are multifaceted. For public health officials and regulatory bodies, the evidence supports the need for stringent regulations to limit cadmium exposure in both environmental and occupational settings. Implementing monitoring programs to assess cadmium levels in at-risk populations can aid in early detection and intervention. For the food industry, particularly manufacturers of products like chocolate and leafy vegetables, adherence to established cadmium limits is crucial to ensure consumer safety. The findings also suggest that integrating cadmium exposure assessments into routine health check-ups could be beneficial, especially for individuals with known risk factors.

Cadmium is a persistent heavy metal that accumulates in kidneys and bones. Dietary sources include cereals, cocoa, shellfish and vegetables, while smokers and industrial workers receive higher exposures. Studies link cadmium to kidney dysfunction, bone fractures and cancer.
