Abstract： 目的研究三峡库区中年人QT间期值与心脏危险因素.方法对中年男性5 500例和女性5500例的QTLC与心脏危险因素及其死亡率的关系进行分析.结果QTLC延长与高血压和心血管疾病信号有关;QTLC缩短与吸烟有关.心血管死亡率QTLC延长5%～10%为2.47%,延长>10%为4.56%;QTLC缩短5%～10%为1.10%,缩短>10%为1.43%.吸烟者死亡率QTLC缩短5%～10%为0.23%,缩短>10%为1.25%;QTLC延长5%～10%为0.27%,延长>10%为0.50%.结论中年人QTLC延长是预测心血管病死亡率的危险指标,心血管病吸烟者QTLC缩短也是预测心脏死亡的危险指标.
