The results of coronarography of 145 patients with unstable angina and 102 patients with a stable course of the disease are presented. The findings obtained were analyzed with regard to the clinical variant of progressive coronary insufficiency. It was found that both in patients with progressive angina and in those suffering from attacks of acute coronary insufficiency following the preceding angina, the degree of obstructive damage was virtually the same as in stable angina. At the same time almost half the patients suffering from attacks of acute coronary insufficiency with no history of previous angina showed normal or only slightly altered coronary arteries. The mentioned specific features of the morphological changes seen in a group of patients with acute coronary failure suggest that spasm of the coronary arteries may underlie the pathogenesis of its attacks in patients without a previous history of angina.
本文呈现了145例不稳定型心绞痛患者和102例病情稳定患者的冠状动脉造影结果。针对进行性冠状动脉供血不足的临床变体对所得结果进行了分析。结果发现，无论是进行性心绞痛患者，还是在先前心绞痛发作后出现急性冠状动脉供血不足发作的患者，阻塞性损伤程度与稳定型心绞痛患者基本相同。与此同时，几乎一半无先前心绞痛病史的急性冠状动脉供血不足发作患者显示冠状动脉正常或仅有轻微改变。在一组急性冠状动脉衰竭患者中观察到的形态学变化的上述特定特征表明，冠状动脉痉挛可能是无先前心绞痛病史患者发作的发病机制基础。
