定量冠状动脉血管造影术,结合多普勒和PET,最近已被定向在人类的α-肾上腺素能冠状动脉血管运动的研究。与先前的动物实验相同,没有证据表明静息时α-肾上腺素能冠状动脉缩窄肌张力。再次证实了先前的实验,在冠状动脉内皮功能障碍和动脉粥样硬化的存在下,对α-肾上腺素受体激活的反应增强,涉及心外膜管道动脉和微血管中的α(1)-和α(2)-肾上腺素受体。在运动和冠状动脉介入治疗期间观察到这种增强的α-肾上腺素能冠状动脉收缩,并且其足以诱导心肌缺血并限制心肌功能。最近的研究表明,α(2)-肾上腺素能冠状动脉狭窄的遗传决定。
The use of quantitative coronary angiography, combined with Doppler and PET, has recently been directed at the study of alpha-adrenergic coronary vasomotion in humans. Confirming prior animal experiments, there is no evidence of alpha-adrenergic coronary constrictor tone at rest. Again confirming prior experiments, responses to alpha-adrenoceptor activation are augmented in the presence of coronary endothelial dysfunction and atherosclerosis, involving both alpha(1)- and alpha(2)-adrenoceptors in epicardial conduit arteries and microvessels. Such augmented alpha-adrenergic coronary constriction is observed during exercise and coronary interventions, and it is powerful enough to induce myocardial ischemia and limit myocardial function. Recent studies indicate a genetic determination of alpha(2)-adrenergic coronary constriction.
