Four cases of the intermediate coronary syndrome were described, all of which were difficult to differentiate from the myocardial infarction. In this syndrome, the cases showing a series of changes have been seen between the angina pectoris and the myocardial infarction. Although the intermediate coronary syndrome includes all of these cases together at the present, some of them are intimately related to the myocardial infarction while the others are close to the classical form of the angina pectoris. Post-mortem examination has revealed high incidence of the myocardial infarction in the patients who had been diagnosed as intermediate coronay syndrome during their lives. Considering from this fact, the author emphasizes that clinician should be prudent not to abuse the term of an intermidate type merely in virtue of its convenience, since the myocardial infarction or undifferential case is not belonging to this syndrome.
