ATVB:中年人血管功能的昼夜节律

2019-04-19 xing.T 网络

由此可见,在早晨易受损期,内源性昼夜节律系统损害VEF,并增加丙二醛加合物和ET-1,并且可能增加易感个体早晨不良心血管事件的风险。

不良血管事件发生在早晨比在一天中其他时间更频繁。血管内皮功能(VEF)-心血管风险标志物,在早晨期间易受损。研究人员最近发现,早晨VEF受损不是由于过夜睡眠或伴随睡眠的不活动所引起的。近日,心血管领域权威杂志Arteriosclerosis, Thrombosis, and Vascular Biology上发表了一篇研究文章,研究人员旨在明确内源性昼夜节律系统是否导致VEF早晨受损。研究人员还评估了昼夜节律系统是否影响机械生物标志物,即氧化应激(丙二醛加合物)、ET-1(内皮素-1)、血压和心率。

二十一(11名女性)中年健康参与者在昏暗的灯光下完成了为期5天的试验方案,其中所有行为,包括睡眠和活动,以及所有生理指标均匀分布在24小时内。在基线检检测后,参与者进行了10次重复的5小时20分钟行为周期,其中2小时40分钟的睡眠和2小时40分钟的标准化清醒。研究人员测量了参与者的VEF、血压和心率,并且在每次苏醒期间唤醒后立即对参与者进行静脉血液取样。

独立于行为,VEF在夜间和整个早晨显著减弱(P=0.04)。丙二醛加合物和ET-1表现出昼夜节律,早晨易受损期增加,中午出现峰值(P≤0.01)。收缩压(P=0.005)和舒张压(P=0.04)都是节律性的,在下午晚些时候达到峰值。

由此可见,在早晨易受损期,内源性昼夜节律系统损害VEF,并增加丙二醛加合物和ET-1,并且可能增加易感个体早晨不良心血管事件的风险。

Circulation:定期运动可改善久坐不动的中年人的心肌僵硬度,从而预防心衰

中年人的健康状况欠佳是导致心力衰竭的风险因素,尤其是对射血分数受损的心衰。射血分数受损性心衰的进展可能是通过增加左心室(LV)的僵硬度(久坐老化的结果)来调节的。近日,Circulation杂志上发表一篇文献,研究人员进行一前瞻性的、平行随机对照试验,评估高强度锻炼2年对LV僵硬度的影响。共招募61位(48%男性)健康、久坐的中年受试者(53±5年),随机分至锻炼组(34位)或观察对照组(27位)
