JCEM:25(OH)D水平或可反应心血管疾病风险

2013-10-21 desperado-c dxy

多项研究提示低血清25–羟维生素D[25(OH)D]浓度与高心血管疾病(CVD)风险有关,但这方面的证据仍不确定,多数证据基于CVD死亡率,且研究中的25(OH)D测量方法单一。为在同一的研究人群中通过重复测量25(OH)D并分析竞争风险,以评估25(OH)D与致命性和非致命性CVD的关系,来自德国癌症研究中心的Laura Perna教授及其团队进行了一项研究,发现低25(OH)D水平与CVD风险


血清25羟维生素D水平与心血管疾病、冠心病和中风的关系

多项研究提示低血清25–羟维生素D[25(OH)D]浓度与高心血管疾病(CVD)风险有关,但这方面的证据仍不确定,多数证据基于CVD死亡率,且研究中的25(OH)D测量方法单一。为在同一的研究人群中通过重复测量25(OH)D并分析竞争风险,以评估25(OH)D与致命性和非致命性CVD的关系,来自德国癌症研究中心的Laura Perna教授及其团队进行了一项研究,发现低25(OH)D水平与CVD风险中度增加相关。该研究结果在线发表于2013年10月8日的The Journal of Clinical Endocrinology & Metabolism杂志上。【原文下载】

该研究为一项以人群为基础的队列研究(ESTHER研究,基线2000-2002年),分别于基线后2年、5年和8年收集随访数据,生存者响应率为99.9%。研究受试者由他们的全科医师在健康普查过程中招募。在基线和随访5年后收集血液标本测量25(OH)D。共9949例男女受试者纳入该研究,基线年龄50-74岁,均有足够的德语知识并居住在德国萨尔州。主要评价指标包括总的心血管疾病、冠心病(CHD)和中风事件,并区分致命性和非致命性事件。

该研究结果发现,总体来说,8年随访期间,854例受试者发生非致命性CVD事件,176例受试者发生致命性CVD事件。在校正了重要的潜在混杂因素的模型中,25(OH)D水平低于30nmol/l的受试者与25(OH)D水平高于50nmol/l受试者相比,总CVD风险比为1.27,致命性CVD风险比为1.62。非致命性CVD与25(OH)D水平之间没有观察到明显的相关性。在剂量-反应分析中,观察到在25(OH)D水平低于75nmol/l时,心血管风险增加。CHD和中风的结果与CVD综合结果相似。

该研究结果表明,25(OH)D水平低与CVD风险中度增加有关,并且致命性CVD事件与25(OH)D的相关性显著强于非致命性CVD事件。
