Circ Heart Fail:促红细胞生成素水平升高与老年人心衰发生相关

2016-01-13 phylis 译 MedSci原创

背景:研究表明,心衰患者(HF)、高血红细胞生成素与复发性心衰和死亡发生相关。在肾脏病患者促红细胞生成素刺激剂的试验中,发现不良临床事件的增加。没有大型的研究,评估社区老年人内源性促红细胞生成素水平与临床预后的相关性。方法和结果:在健康、老龄化和身体组成的研究中,检测2488名年龄在70-79岁的促红细胞生成素的浓度。随访时间超过10.7年,应用Cox比例风险模型和Logistic回归检测促红细胞

背景:既往的研究表明,心衰患者(HF)、高血红细胞生成素与复发性心衰和死亡发生相关。研究人员曾在肾脏病患者促红细胞生成素刺激剂的试验中,发现不良临床事件的增加。然而,没有大型的研究,评估社区老年人内源性促红细胞生成素水平与临床预后的相关性。

方法和结果:在健康、老龄化和测量身体成分的研究中,检测2488名年龄在70-79岁的促红细胞生成素的浓度。随访时间超过10.7年,应用Cox比例风险模型和Logistic回归检测促红细胞生成素与心衰、冠心病、中风、死亡、估算肾小球滤过率下降≥30%的相关性。患者平均年龄(SD)为75(3)岁,促红细胞生成素的中位数为(第1四分位数,第3四分位数)12.3(9,17.2)mIU/mL。

共有503例心衰事件的发生,校正人口学资料、心血管疾病、心血管疾病的危险因素、肾功能和血清血红蛋白后:血清促红细胞生成素的浓度每增加一倍,心衰1.25(95%CI: 1.13,1.48)发生风险提高25%。血清促红细胞生成素与慢性肾脏病、贫血无交互作用。共发生330例冠心病事件,161例卒中,1112人死亡,698例肾小球滤过率下降≥30%。血清促红细胞生成素与这些预后没有显著相关性。

结论:内源性促红细胞生成素较高与老年人的心衰发生相关。研究需要阐明内源性促红细胞生成素水平与特定的结果相关的机制。
