심부전 환자에서 발생한 반복적인 자발성 저혈당과 의식저하 1예

초록

Hypoglycemia in adults without diabetes can be caused by drugs, critical illness, hormone deficiency, and hyperinsulinism. Spontaneous hypoglycemia in congestive heart failure has been reported rarely in adults. We report a case of spontaneoushypoglycemia in congestive heart failure in a 73-year-old woman with mitral stenosis and atrial fibrillation who had been receivingtreatment for 6 years. She had two episodes of low serum glucose with unconsciousness, but there was no evidence of diabetes. Heart failure with concomitant hepatic dysfunction was presumed to have caused the hypoglycemia. She underwent mitral valvereplacement after being diagnosed with severe mitral stenosis. There was no episode of hypoglycemia during follow-up.
