Mounting evidence supports that cadmium, a toxic metal found in tobacco, air and food, is a cardiovascular risk factor. Our objective was to conduct a systematic review of epidemiologic studies evaluating the association between cadmium exposure and cardiovascular disease. Twelve studies were identified. Overall, the pooled relative risks (95 % confidence interval) for cardiovascular disease, coronary heart disease, stroke, and peripheral arterial disease were: 1.36 (95 % CI: 1.11, 1.66), 1.30 (95 % CI: 1.12, 1.52), 1.18 (95 % CI: 0.86, 1.59), and 1.49 (95 % CI: 1.15, 1.92), respectively. The pooled relative risks for cardiovascular disease in men, women and never smokers were 1.29 (1.12, 1.48), 1.20 (0.92, 1.56) and 1.27 (0.97, 1.67), respectively. Together with experimental evidence, our review supports the association between cadmium exposure and cardiovascular disease, especially for coronary heart disease. The number of studies with stroke, heart failure (HF) and peripheral arterial disease (PAD) endpoints was small. More studies, especially studies evaluating incident endpoints, are needed.

This is a large prospective study representative of the general US population from 1999–2004 with 8 years of follow-up. After adjusting for sociodemographic and CVD risk factors, including smoking status, recent smoking dose, and cumulative smoking dose increasing cadmium exposure was associated with cardiovascular disease, heart disease and coronary heart disease mortality

This is a prospective study of 64-year-old women from Sweden, with 6 years of follow-up. In this study, baseline cadmium exposure was associated with peripheral arterial disease measured at the end of the follow-up. The association appeared to be non-lineal, although the number of cases at the lower range of cadmium levels was limited.

This is a large prospective study of Japanese inhabitants of a cadmium-polluted area, with 22-year follow-up. In this study, cadmium exposure as measured in urine was associated with cardiovascular disease mortality in both men and women, and with stroke mortality only in women. A limitation of this study is the lack of adjustment for smoking and other relevant cardiovascular risk factors. An additional limitation is that the number of cardiovascular deaths is limited, specially for women
