Angiographically demonstrable collateral flow occurred immediately when coronary arterial spasm was induced by ergonovine in two patients with angina who had organic stenosis of less than 40 percent. These findings suggest that coronary collaterals may develop in response to intermittent brief myocardial ischemia in man, and that collaterals may be preserved even if they are closed at rest and can immediately function when a coronary artery is acutely occluded.
在两名患有心绞痛且器质性狭窄小于40%的患者中，当用麦角新碱诱发冠状动脉痉挛时，血管造影可显示的侧支血流立即出现。这些发现提示，人类的冠状动脉侧支可能是对间歇性短暂心肌缺血的反应而形成的，并且即使这些侧支在静息时关闭，但当冠状动脉急性闭塞时它们可能立即发挥作用，侧支也可能得以保留。
