THE EFFECTS OF PHYSIOLOGICAL STRESS ON CORONARY CIRCULATION

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 中心，不一定是研究者的机构。 本研究的目的是确定在静态握力运动、随意和不随意肌肉收缩、低氧/高氧/高碳酸血症、下体负压和冷加压试验条件下生理应激对人体冠状动脉血流的影响。 将使用超声心动图测量冠状动脉血流。

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. The aim of this study is to determine the effects of physiological stress on coronary blood flow in humans under conditions of static hand grip exercise, voluntary and involuntary muscle contraction, hypoxia/hyperoxia/hypercapnia, lower body negative pressure and cold pressor test. Coronary flow will be measured with echocardiography.
