Activity of angiotensin converting enzyme in women with hypothyroidism]

Serum activity of angiotensin converting enzyme (ACE) has been measured in 13 women (mean age 43.1 years) with primary hypothyroidism by spectrofluorometric method of Friedland and Silverstein. The mean enzyme activity was significantly lower in hypothyroid patients than in healthy persons. There is no significant correlation between ACE activity and thyroid hormones concentration.
