Different countries, different risks. Selenium deficiency-related heart disease depends on where one lives. That’s another reason why monitoring is so important.

Keshan disease is a cardiovascular condition related to selenium deficiency. It occurs mostly in China, where some soils are extremely selenium deficient. In Europe, many geographical regions are selenium deficient. Poor selenium status is related to the risk of heart disease and cardiovascular death. This especially applies to the elderly. Improved selenium status can reduce the risk of coronary artery disease. 

One meta-analysis showed that doubling the selenium concentrations could reduce the heart disease risk by almost a quarter. That is one more reason why selenium status should be checked regularly in patients with heart disease. Selenium content can be monitored in the serum and whole blood. The experts at biosyn offer competent testing and advice on this important risk factor.
