Historical lead exposure may be linked to 256,000 premature deaths from cardiovascular disease in adults in the USA each year

http://ift.tt/eA8V8J New estimates suggest that 256,000 premature deaths from cardiovascular disease – including 18,5000 deaths from ischemic heart disease – in the USA may be linked to historical lead exposure in middle-aged and older adults (people currently aged 44 years or over), according to an observational study. Previous estimates, which assumed that low-level lead exposure did not increase the risk of premature death, produced substantially fewer deaths. However, this new study finds that low-level lead exposure (between 1-5 micrograms of lead per deciliter of blood) increases the risk of premature death, especially from cardiovascular disease. Lead exposure is linked to high blood pressure, hardening of the arteries and ischemic (coronary) heart disease.
