Prevalence of arterial hypertension and cardiovascular risk factors in a rural population exposed to arsenic in Argentina.

Exposure to As does not affect the prevalence of CRFs. We identified a rural population in a vulnerable condition with high CRFs. The National Risk Factor Survey does not reflect what happens in rural areas. The Framingham scale is consistent with the found CRFs. The implementation of health promotion policies is required to improve the prognosis of suffering cardiovascular events in the short and medium term.
