美国科学新闻网:吸电子烟可能会像吸烟一样危害心脏

据美国科学新闻网报道,从吸烟转为吸电子烟可能对心血管健康没有帮助。
 
研究人员在400多名21至45岁的健康成年人的血管系统上进行了测试。
 
波士顿大学医学院血管生物学家杰西卡·费特曼(Jessica Fetterman)说,这种僵硬会损害小血管并使心脏紧张,这两者都可能导致心血管疾病的发展。
 
Fetterman及其同事还收集了血管内衬细胞的参与者样本,并将这些细胞暴露于荧光染料中,该荧光染料可检测一氧化氮,该分子可扩张血管并有助于阻止血液凝结。与不吸烟或不吸烟的参与者的细胞相比,从吸烟者和电子烟用户中的细胞产生的一氧化氮要少,这表明吸烟者和电子烟用户的血管可能无法正常工作。
 
心血管疾病是吸烟者死亡的主要原因,一些人认为改用电子烟对健康的危害较小。许多使用电子烟的成年人以前都是吸烟者,这对本研究中的电子烟使用者而言确实如此。
 
电子烟的研究参与者已经这样做了至少三个月。先前的研究表明,健康的戒烟者可以在短短四个星期内看到其动脉僵硬程度降低。
 
Fetterman说,我们的工作表明,电子烟使用者的血管僵硬异常仍然存在。没有证据表明,使用电子烟可以减少心血管损伤。

  1. Hey there! I know this is somewhat off-topic however I needed to ask.

    to share my own experience and views online. Please let me know if you have any recommendations or tips for new aspiring bloggers.

  6. Hey there just wanted to give you a quick heads up. The words in your article seem to be
    running off the screen in Opera. I’m not sure if this is a formatting issue or something to do with web browser compatibility but I figured I’d post to let you know.
