Eur J Prev Cardiol:微血管内皮功能紊乱还能预测癌症

2019-11-08 朱朱 中国循环杂志

微血管内皮功能紊乱是心血管疾病的常见早期表现。但是,近期发表在《欧洲预防心脏病学杂志》上的一项美国研究提示,微血管内皮功能紊乱可能还是癌症的早期标志,可提前5年以上预测实体恶性肿瘤的发生。

血管内皮功能紊乱是心血管疾病的常见早期表现。但是,近期发表在《欧洲预防心脏病学杂志》上的一项美国研究提示,微血管内皮功能紊乱可能还是癌症的早期标志,可提前5年以上预测实体恶性肿瘤的发生。

研究者发现,中位随访6.0年(最长随访12年)期间,存在微血管内皮功能紊乱的人未来出现实体恶性肿瘤的风险是微血管内皮功能完好者的2倍以上,前者的无癌生存率明显低于后者。

Cox比例风险分析显示,校正性别、年龄和冠心病后,存在微血管内皮功能紊乱的患者罹患实体恶性肿瘤的风险增加1.52倍;校正糖尿病、吸烟状态、高血压和肥胖(体重指数>30 kg/m2)后,患癌风险增加1.83倍;校正收缩压、空腹血糖、体重指数和既往或当前吸烟后,患癌风险增加1.79倍;校正弗雷明汉风险评分后,患癌风险增加1.43倍。

研究还显示,微血管内皮功能紊乱与癌症独立相关,但两者之间的关系在男性患者以及合并高血压、冠心病、吸烟和肥胖的患者中更明显。

研究者指出,对于微血管内皮功能紊乱的患者,临床医生除了要评估其心血管风险,还要评估患癌的风险。目前还不清楚微血管内皮功能紊乱与癌症相关的潜在机制,还需要进一步探索。

该研究纳入488例于美国梅奥医疗中心就诊并接受内皮功能检测的患者,其中45%存在微血管内皮功能紊乱。随访期间,存在微血管内皮功能紊乱的患者中9.5%诊断为实体恶性肿瘤,发生率明显高于微血管内皮功能完好者(3.7%)。

在该研究中,488例患者通过反应性充血外周动脉张力计评估微血管内皮功能,反应性充血外周动脉张力≤2.0定义为微血管内皮功能紊乱。
