Exposure even to low to moderate arsenic levels over many years may increase the risk of developing cardiovascular disease and dying of cardiovascular problems compared with very little or no exposure.

In a recent study, investigators examined the relationship between cardiovascular health and arsenic levels in urine samples from 3575 American Indian adults who were first examined in 1989-1991 and followed up through 2008. Participants with the highest levels of arsenic in their urine were more likely to both develop cardiovascular disease and die of it than participants with lower levels of arsenic in their urine.
