The authors have studied the frequency and severity of anginal attacks of the Prinzmetal type coming on during the acute phase of a myocardial infarction in 13 patients. They have occurred in 5.50% of cases (anginal attacks of all types occurring in 18.34% of cases). The severity of these attacks is shown by their clinical features: the multiplicity of the attacks, the high incidence of arrhythmias, the difficulties encountered with medical treatment. This also confirmed by the enzyme studies: when the curve of myocardial creatinine kinase release is drawn, there is seen to be an extension of the lesion in 2/3 cases, whereas the electrocardiograph does not show this up.
作者研究了13例心肌梗死急性期发生的变异型心绞痛发作的频率和严重程度。其发生率为5.50%（各类心绞痛发作发生率为18.34%）。这些发作的严重程度通过其临床特征表现出来：发作次数多、心律失常发生率高、药物治疗困难。酶学研究也证实了这一点：绘制心肌肌酸激酶释放曲线时，2/3的病例可见病变范围扩大，而心电图却未显示出来。
