Abstract

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 spontaneous hypoglycemia in congestive heart failure in a 73-year-old woman with mitral stenosis and atrial fibrillation who had been receiving treatment 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 valve replacement after being diagnosed with severe mitral stenosis. There was no episode of hypoglycemia during follow-up.
