A Case of Microvascular Angina Treated with Dai-kankyo-to / 日本東洋医学雑誌

ABSTRACT

A 72-year-old female who had been experiencing chest pain after slight exertion for over one month was admitted to our hospital. An electrocardiogram after exercise revealed a myocardial ischemic change. We diagnosed Ketsu-kyo on the basis of symptoms such as extreme tenderness in the epigastric region (Shinka-hiko) and also tenderness in the anterior chest wall. After prescribing Dai-kankyo-to, which was made by boiling with Daio, Bosyo and Kantsui, the expected diarrhea did not occur. We then made Dai-kankyo-to according to the original method of Sho-kan-ron and administered it. The chest pain disappeared and severe diarrhea occurred. A coronary angiogram did not reveal a stenotic lesion and the patient was diagnosed with microvascular angina pectoris. This suggests that Dai-kankyo-to may be an effective treatment of microvascular angina in its acute stage.
