本文所述方法可在单个诊所或实验室访问中进行无创、无反应性充血、神经血管耦合和骨骼肌氧化能力的临床评价。
关键考虑事项
虽然近红外光谱是相对健壮和易于使用, 收集这些数据需要仔细放置的 optodes 直接在肌肉腹部, 固定到位, 以避免运动工件, 并覆盖在昏暗的房间里的黑色乙烯基板, 以避免外部光对近红外的干扰。此外, 获得?...

充血对短暂的组织缺血的反应已成为一种关键的非侵入性测量 (微) 血管功能。在导管动脉闭塞期间, 下游动脉扩张, 以抵消缺血性的侮辱。在阻断后, 血管阻力的减少导致充血, 其大小取决于一个人的能力来扩张下游微管。虽然反应性充血是心血管事件的一个强有力的独立预测因子1,2 , 因此一个临床重要的终点, 它的功能意义, 锻炼耐受性和生活质量是不太清楚。
事实上, 动态运动是一种主要的心血管压力, 需要高度协调的神经血管反应, 以便将氧气输送与新陈代谢需求相匹配。例如, 骨骼肌血流可以增加近100倍, 在单独的肌肉收缩3, 这将压倒心脏的抽水能力, 如果这样的血流动力学反应被推断为全身运动。因此, 为了避免严重的低血压, 交感神经 (即,收缩) 神经活动增加, 重新分配心脏输出远离非活动和内脏组织和对主动骨骼肌4。交感神经流出也被定向到运动骨骼肌5;然而, 局部代谢信号减弱收缩反应, 以确保足够的组织氧气输送6,7,8,9,10, 11. 总的来说, 这个过程被称为功能 sympatholysis12, 对运动过程中骨骼肌血流的正常调节是必不可少的。由于骨骼肌血流是有氧能力的关键决定因素--生命质量和心血管疾病发病率和死亡率的独立预测因子13-了解骨骼肌血流和组织氧的控制运动期间分娩具有重要的临床意义。
然而, 氧气的传递只是菲克方程的一半, 氧气的利用满足了等式的另一半。在氧利用的主要决定中, 线粒体氧化磷酸化对于在静止和运动期间为细胞过程提供足够的能量起着至关重要的作用。事实上, 肌肉氧化能力的损害可以限制功能能力和生活质量14,15,16。各种措施通常用于提供肌肉氧化能力指标, 包括侵入性肌肉活检和昂贵和耗时的磁共振光谱学 (夫人) 技术。
在这里, 我们提出了一种新的, 非侵入性的方法, 使用近红外光谱分析, 以评估这三个主要临床终点 (活性充血, sympatholysis 和肌肉氧化能力) 在一个单一的诊所或实验室访问。该方法的主要优点是三倍: 首先, 该技术易于携带, 成本相对较低, 易于执行。目前的多普勒超声检测反应性充血的方法是高度依赖于操作者-需要广泛的技能和培训-并需要复杂, 高成本, 数据采集硬件和后处理软件。此外, 这可能被引入到临床和/或大型临床试验, 为床边监测或测试的疗效。其次, 根据该方法, 该技术特别注重骨骼肌微血管, 提高了技术的整体特异性。其他方法使用多普勒超声聚焦在上游导管容器和推断变化下游, 这可能会减弱信号。第三, 这种技术是完全无侵入性的。骨骼肌氧化能力传统上是用侵袭性和痛苦的肌肉活检来评估的, 功能 sympatholysis 可以用动脉内注射 sympathomimetics 和 sympatholytics 来评估。这种方法完全避免了这些要求。

skeletal muscle neurovascular coupling, oxidative capacity, and microvascular function with 'one stop shop' near-infrared spectroscopy

运动是一种主要的血流动力学压力, 需要高度协调的神经血管反应, 以便将氧气输送与新陈代谢需求相匹配。反应性充血 (在短时间内组织缺血) 是心血管事件的独立预测因子, 为血管的健康和舒张能力提供了重要的洞察力。骨骼肌氧化能力在健康和疾病中同样重要, 因为它决定了 myocellular 过程的能量供应。在这里, 我们描述了一个简单的, 非侵入性的方法, 使用近红外光谱评估这些主要临床终点 (反应性充血, 神经血管耦合, 肌肉氧化能力) 在一个单一的诊所或实验室访问。不同于多普勒超声, 磁共振图像/光谱学, 或侵入导管的流量测量或肌肉活检, 我们的方法是较少的操作者依赖, 低成本, 完全没有侵入。我们实验室的代表性数据连同先前发表的文献中的摘要数据, 说明了每个端点的效用。一旦掌握了这种技术, 应用到临床人群将提供重要的机械洞察力的运动不耐受和心血管功能障碍。
