History of Changes
  Purpose

Having too little or too much GH are both associated with heart disease.

The purpose of this research study is to study the effects of growth hormone (GH) replacement on the heart. We will study these effects in people who have been cured of acromegaly and then have developed growth hormone deficiency (GHD, not enough growth hormone).


Condition Intervention
Acromegaly
 Procedure: echocardiogram

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective
Official Title: Effects of Physiologic Growth Hormone Administration on Echocardiographic Parameters in Subjects With Growth Hormone Deficiency Following Cure of Acromegaly

Estimated Enrollment: 20
Study Start Date: February 2011

Groups/Cohorts Assigned Interventions
AcroGHD on GH
Men and women with growth hormone deficiency following cure of acromegaly who are receiving growth hormone treatment.
 Procedure: echocardiogram
An echocardiogram will be performed in all subjects at baseline and at one year.
AcroGHD not on GH
Men and women with growth hormone deficiency following cure of acromegaly who are not receiving growth hormone treatment.
 Procedure: echocardiogram
An echocardiogram will be performed in all subjects at baseline and at one year.
