: The author depicted several cases of myocardial infarction which onset or preinfarction angina symptoms were taken by the patients for a catarrhal disease. The signs enabling the doctor to exclude the "catarrhal" origin of patient's feelings were indicated. The author suggested that the term of "catarrhal" variant of myocardial infarction onset" should be used as a pattern of its atypical onset.
