A 34-year-old female patient who presented to our hospital had been treated with insulin for diabetes since she was 25 year old. For the previous year she had experienced chest pain on exertion and during hypoglycemia. During both chest pain and exercise tests, ST depression and flattening of the T wave were recognized in leads II, III, aVF, and V2-V6 on the electrocardiogram, and thus ischemic heart disease was suspected. Cardiac catheterization was performed, but no organic stenosis or spasms were found. Hypoglycemia (41 mg/dl) was induced by intravenous injection of rapid insulin (total 18 U, 0.4U/kg). However, no coronary change was seen, although she felt chest pain and the same ischemic electrocardiographic changes occurred. We hypothesized the causes of the ischemic change to be both the effects of insulin on the cardiovascular system and the physiologic stress induced by the existence of microvascular abnormality. Special care should therefore be taken with diabetic patients being treated with insulin or hypoglycemic agents. (Jpn Circ J 1998; 62: 142 - 145)
