Neurology:血清镁和钙水平与缺血性卒中有关

2019-02-02 xing.T MedSci原创

由此可见,该研究发现遗传上较高的血清镁浓度与心源性卒中风险降低有关,但未发现遗传性较高的血清钙浓度与任何缺血性卒中亚型之间的显著相关性。

近日,神经病学领域权威取杂志Neurology上发表了一篇研究文章,研究人员旨在使用孟德尔随机化方法确定血清镁和钙浓度是否与缺血性卒中或其任何亚型之间存在因果关系。

研究人员使用与血清镁(n=6)或血清钙(n=7)浓度稳健相关的13个单核苷酸多态性的汇总统计数据进行分析。缺血性卒中的相应数据来自MEGASTROKE联合体(34217例病例和404630例非病例)。

在标准孟德尔随机分析中,遗传预测血清镁浓度每增加0.1 mmol/L(约1个SD),对于所有缺血性卒中的比值比为0.78(95%置信区间[CI]为0.69-0.89; p=1.3×10-4),心源性卒中的风险比为0.63(95%CI为0.50-0.80; p=1.6×10-4),大动脉卒中的风险比为0.60(95%CI为0.44-0.82; p=0.001)。但与小血管卒中无相关性(比值比为0.90,95%CI为0.67-1.20; p=0.46)。只有与心源性卒中的关联在敏感性分析中才是稳健的。遗传预测的血清钙浓度与所有缺血性卒中无关(血清钙每升高0.5mg/dL[约1个SD]:比值比为1.03,95%CI为0.88-1.21)。

由此可见,该研究发现遗传上较高的血清镁浓度与心源性卒中风险降低有关,但未发现遗传性较高的血清钙浓度与任何缺血性卒中亚型之间的显著相关性。
