摘要

The aim of this study was to investigate arsenic-related cardiovascular risks in apparently healthy people chronically exposed to low level of arsenic in drinking water. This cross-sectional study compared cardiovascular risk parameters between arsenic-exposed group (51 μg/L) and non-exposed group (no detectable arsenic). Systemic arterial Blood Pressure (BP), corrected QT interval (QTc) and Ankle Brachial Pressure Index (ABPI) were assessed as cardiovascular risk parameters. All cardiovascular risk parameters were within normal limits in both groups. However, the estimated risk of high normal mean arterial blood pressure, borderline prolongation of QTc interval and borderline decrease in ABPI were 5.3, 1.3 and 2.1 times higher in the exposed group than the non-exposed group, respectively. This study finds increased level of cardiovascular risk in people exposed to the low level of arsenic (51 μg/L) in drinking water.
