Thyroid Hormone After Heart Bypass for Mild Underactive Thyroid
Treatments studied
Part of Heart & circulation, Hormones & metabolism clinical trials.
This study looks at whether giving thyroid hormone replacement to people with mild underactive thyroid (subclinical hypothyroidism) after heart bypass surgery improves their recovery. It is for adults who are scheduled for bypass surgery and have not recently used thyroid or anti-thyroid medications.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 19 and 90 years old.
- You are scheduled for coronary artery bypass graft (CABG) surgery, also known as heart bypass surgery.
- You have subclinical hypothyroidism – a mild underactive thyroid where your TSH level is slightly high (above 4) but your free T4 is normal.
- You have not taken thyroid hormone medication (levothyroxine) in the past 4 weeks.
- You have not taken antithyroid drugs (like propylthiouracil, methimazole, or carbimazole) in the past 3 months.
- You do not have a serious illness expected to shorten your life to less than one year, such as advanced cancer.

This trial tests whether a thyroid hormone medication (levothyroxine) can improve heart function in children who have slightly high TSH levels but normal thyroid hormones. It may help children aged 4 to 15 with subclinical hypothyroidism.
This study looks at whether having a mild thyroid issue (called subclinical hypothyroidism) affects your liver enzymes and cholesterol levels. If you have this condition, participating could help doctors understand how it impacts your health.
This study tests whether giving a thyroid hormone supplement called levothyroxine before a heart transplant can help with recovery. It is for people already listed for a heart transplant who do not have thyroid problems.
This trial is testing whether thyroid hormone replacement after surgery is safe for people with low-risk papillary thyroid cancer. It may help maintain normal hormone levels after part of the thyroid is removed.
This study tests a new way of providing thyroid hormone therapy for people who still feel tired and other bothersome symptoms despite currently taking a standard thyroid pill (levothyroxine). It combines two types of thyroid hormone (T4 and T3) to see if it better relieves symptoms than the usual treatment.
This study looks at whether a simple, non-invasive test of blood pressure can predict the risk of heart disease over 10 years in people with an underactive thyroid (subclinical hypothyroidism). It may help doctors better identify who needs closer monitoring.
