This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Exercising muscle needs more blood than resting muscle. Therefore, when a person exercises, their body needs to divert blood from resting muscles to 'feed' the exercising muscles. The mechanism that allows exercising muscles to demand more blood while resting muscles have decreased blood flow is not understood. Many scientists feel that this process has to do with receptors on the cells of the muscles and blood vessels. This study is designed to give certain drugs (that are known to affect certain receptors) to decrease the signal of the exercising muscle to demand blood flow. This study will compare these responses between people diagnosed with Heart Failure and normal people. 45 volunteers will be in this study.

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。锻炼肌肉比休息肌肉需要更多的血液。因此，当一个人锻炼时，他们的身体需要将休息肌肉中的血液转移到锻炼肌肉中。运动肌肉需要更多的血液，而休息的肌肉却减少了血流量，其机制尚不清楚。许多科学家认为，这一过程与肌肉和血管细胞上的受体有关。这项研究的目的是给某些药物(已知会影响某些受体)，以减少运动肌肉要求血液流动的信号。这项研究将比较被诊断为心力衰竭的人和正常人的这些反应。45名志愿者将参与这项研究。
