  • Abstract
  • Look Inside

A 42-year-old man and a 31-year-old man with congestive heart failure caused by the thyroid stimu-lating hormone (TSH) secreting pituitary adenoma were reported. Heart failure was improved after transsphenoidal resection of the pituitary adenoma in each patient.

The syndrome of inappropriate secretion of TSH causes hyperthyroidism. Thyroid hormone acts di-rectly on cardiac muscle to increase the stroke vol-ume. Hyperthyroidism itself reduces the peripheral vascular resistance and an elevated basal metabolism which is the basic physiologic change in hyperthyroid-ism dilates small vessels and reduces vascular resis-tance.
