乳腺癌筛查也能顺便预测心脏病!美研究称:乳腺动脉钙化提示心脏病风险高

2020-01-12 xujing 中国循环杂志

通过乳房X光检查进行乳腺癌筛查,可以挽救数十万人的生命。通常建议女性从40或50岁开始,每年或两年进行一次乳房X光检查。美国研究者发现,利用这一项已经被广泛应用的检查,在不增加额外的费用或辐射暴露情况下,或许可以筛查心脏病高危人群。除了显示肿块外,数字乳腺摄影还可以显示乳腺动脉钙化情况。据估计,大约13%的女性有乳腺动脉钙化,其中40多岁的女性约占10%,80多岁的女性约占一半。早期的研究发现,乳

通过乳房X光检查进行乳腺癌筛查,可以挽救数十万人的生命。通常建议女性从40或50岁开始,每年或两年进行一次乳房X光检查。

美国研究者发现,利用这一项已经被广泛应用的检查,在不增加额外的费用或辐射暴露情况下,或许可以筛查心脏病高危人群。

除了显示肿块外,数字乳腺摄影还可以显示乳腺动脉钙化情况。

据估计,大约13%的女性有乳腺动脉钙化,其中40多岁的女性约占10%,80多岁的女性约占一半。

早期的研究发现,乳腺动脉钙化的存在预示着心脏病发作、中风和其他心血管病风险增加。

而且有研究提示乳腺动脉中钙的积累和冠状动脉钙化有关。

这项研究分析了2006-2016年278名中老年女性的检查记录,她们在一年的时间内同时接受了乳房X光检查和冠状动脉钙化检查。

研究发现,几乎三分之一的女性患有乳腺动脉钙化,7%患有心力衰竭。

校正了年龄、糖尿病高血压等所有的心力衰竭危险因素后,乳腺动脉钙化女性发生心力衰竭或心力衰竭进展的风险增加2.2倍。

研究者称,乳腺动脉钙化可能是血管僵硬和内皮功能障碍的早期标志物,采用乳腺动脉钙化可以识别出心衰的高危人群。
