[背景]饮用水砷暴露与心脏疾病相关联,然而内在的机制尚不明确。[目的]评估饮用水砷暴露史与心率校正的QT(QTc)、PR和QRS间期延长之间的关联。[方法]从砷对健康影响的纵向研究中选择1715名基线入组的参加者进行研究。评估2005—2010年间,井水中的砷暴露和尿液样本与心电图(ECG)参数的关联,自基线开始平均跟踪了5.9年。[结果]QTc延长的定义为男性QTc≥450ms,女性≥460ms。井水中砷每增加1-SD(108.7μg/L),QTc延长的调整比值比(OR)为1.17(95%CI:1.01～1.35)。正相关仅限于女性,基线时井水和尿液中的砷每增加1-SD,女性调整后ORs分别比为1.24(95%CI:1.05～1.47)和1.24(95%CI:1.01～1.53);与之相比,男性调整后ORs分别为0.99(95%CI:0.73～1.33)和0.86(95%CI:0.49～1.51)。基线时井水砷或尿砷与女性或男性的PR或QRS间期延长之间无明显的关联。[结论]长期饮用水砷暴露(平均95μg/L,全距为0.1～790μg/L)与女性之后的QT间期延长相关联。在今后的纵向研究中,ECG的反复测量对于评估暴露变化的影响将具有重要意义。
