超声和核研究表明，冠状动脉血流随冷压试验（CPT）而改变。CPT已被用于测量冠状动脉血流反应，因为它提供内皮依赖性冠状动脉血管舒张，对检测冠状动脉内皮功能的早期变化很敏感。还有一项研究显示CPT期间心肌灌注增加，伴有第一次灌注成像[1]。研究了正常志愿者在应激状态、静息状态和心肌血流储备状态下的局部心肌灌注值。
Background Echo and nuclear studies have shown that coronary flow changes with the cold pressor test (CPT). CPT has been used to measure coronary flow response because it provides an endothelium-dependent coronary vasodilation that is sensitive for detecting early changes in coronary endothelial function. There was also a study showed myocardial perfusion increases during CPT with first pass perfusion imaging [1]. We studied the regional myocardial perfusion values in normal volunteers under stress (CPT), at rest, and myocardial flow reserve (MFR).
