我们研究了10例频繁自发性冠状动脉痉挛患者的血浆儿茶酚胺水平,以评估交感神经系统的作用。仰卧位和直立位的外周静脉去甲肾上腺素、儿茶酚胺尿排泄和交感神经系统功能测试与对照组的相同测量结果没有差异。动脉和冠状窦去甲肾上腺素和肾上腺素水平在缺血早期未高于基线;冠状窦去甲肾上腺素水平高于动脉组,由ST段抬高时的315±32 (pg/ml±SE)上升至缺血后期的490±49 pg/ml (p< 0.05)。血浆肾上腺素水平,动脉血高于冠状窦血,也仅在缺血后期显著升高,动脉血从44±14 pg/ml上升至148±35 pg/ml (p< 0.05),冠状窦血从33±10 pg/ml上升至108±29 pg/ml (p< 0.05)。全身性交感神经系统激活不太可能是冠状动脉痉挛的唯一原因。
We studied plasma catecholamine levels in 10 patients with frequent spontaneous episodes of coronary artery spasm to evaluate the role of the sympathetic nervous system. Peripheral venous norepinephrine in supine and upright postures, urinary excretion of catecholamines, and functional testing of the sympathetic nervous system did not differ from the same measurements in control subjects. Arterial and coronary sinus levels of norepinephrine and epinephrine drawn early in ischemia were not elevated over baseline; coronary sinus norepinephrine levels were higher than those in arterial samples and rose from 315 ± 32 (pg/ml ± SE) at the onset of ST elevation to 490 ± 49 pg/ml late in ischemia (p< 0.05). Plasma epinephrine levels, higher in arterial than coronary sinus samples, also rose significantly only late in ischemia, from 44 ± 14 pg/ml to 148 ± 35 pg/ml (p< 0.05) in arterial blood and from 33 ± 10 pg/ml to 108 ± 29 pg/ml in coronary sinus samples (p< 0.05). Generalized sympathetic nervous system activation is not likely to be the sole cause of coronary artery spasm.
