Role of Levothyroxine Supplementation in Delayed Recovery Following Cardiac Surgery
Egypt70 participantsStarted 2024-11-30
Plain-language summary
Research indicates that hypothyroidism decreases heart contractility, reduces stroke volume and rate, affects the vascular endothelium, and increases the risk of atherosclerosis, systemic vascular resistance, hypertension, atherogenic lipid profile, and coagulation abnormality .
Hypothyroidism was reported to be strongly related to cardiovascular disease, respiratory complications, neurological complications, and a significant difference in ventilator weaning time.
Once subclinical hypothyroidism patients are treated with levothyroxine, their physical fitness measured by a 6-minute walk is significantly improved, also showed that levothyroxine treatment can optimize the treatment of heart failure with preserved functions (HFpEF) and heart failure with reduced functions (HFrEF) patients with systolic left ventricular dysfunction and sub clinical hypothyroidism (SCH).
The primary aim of this study is to investigate the effect of supplementation of oral levothyroxine in delayed recovery patients post cardiac surgery.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* • Age group: Adult patients from age of 45 to70 years. (Majority of our patients falls in this age group 45-70 years, below these patients are relatively young and usually do not show delayed recovery or prolonged ventilation, while above 70 years are considered frail and more vulnerable to anesthetic medications, so we preferred to exclude them)
* Sex: Both sexes
* Elective, urgent and emergency open heart surgeries. (Most of urgent and emergency cases are either mechanical valve thrombosis or aortic dissection patients, and are more prone to prolonged mechanical ventilation and delayed recovery compared to elective patients)
Exclusion Criteria:
* • Patients refuse to give informed consent.
* Patient younger than 45 years old, older than 70 years old.
* Off pump patients.
* Patients known hypothyroidism on levothyroxine supplementation.
* Patients known hyperthyroidism on Carbimazole.
* Those developing any form of arrhythmia L-Thyroxine will be stopped immediately and the patient will be excluded from the study.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

Change in Glasgow Coma Scale (GCS) From Intervention Initiation to ICU Discharge (Δ)
Timeframe: From intervention initiation (48 hours postoperatively) to ICU discharge, up to 1 month postoperatively. (i.e., within 28 days after baseline).
