摄入单 (Kme) 改善了2型糖尿病成年人的心脏输出量和中风量. 这种干预也增强了休息和运动期间的外周肌肉氧化,而不会影响血管内皮功能.
科学领域:
- 心血管生理学心血管生理学
- 代谢疾病 代谢疾病
- 营养科学 营养科学
背景情况:
- 2型糖尿病 (T2D) 与心血管功能障碍有关,心脏偏爱类作为能量来源.
- 了解营养干预如何影响T2D心脏功能至关重要.
研究的目的:
- 评估摄入单 (Kme) 对T2D患者心脏输出指数 (QTi) 的影响.
- 评估Kme对心脏血液动力学,肌肉氧化和静止和运动期间血管功能的影响.
主要方法:
- 一项双盲,随机,交叉研究,涉及13名患有T2D的成年人.
- 参与者服用了Kme或安慰剂,通过阻抗心脏图测量心脏功能.
- 评估了肌肉氧化,宏血管和微血管内皮功能以及β-基酸盐水平.
主要成果:
- 与安慰剂相比,Kme摄入显著增加了QTi和中风体积指数.
- 周围肌肉的氧化量增加了Kme,而系统性血管抵抗指数下降.
- 没有观察到心率,流媒体扩张或乙胆/胰岛素诱导反应的显著差异.
结论:
- 急性Kme摄入增加了T2D患者的心脏输出量和中风量.
- 在这个人群中,Kme在休息和运动期间改善了外周肌肉的氧化.
- 在T2D患者中,Kme似乎不会影响宏观或微血管内皮功能.
