Study Summary

This trial will elucidate the influence of intense light therapy pretreatment in patients undergoing cardiac surgery. Hypotheses are that intense light exposure is associated with the peripheral stabilization of Per2 in human buccal swabs and plasma samples before surgery and with a decrease of Troponin I levels after surgery. Additionally, light therapy may lead to Per2 dependent metabolic optimization in the human cardiac tissue.

Eligible Conditions
  • Critical Illness
  • Myocardial Ischemia

Trial Design

4Treatment groups
Experimental Treatment
Placebo Group
Group I: Experimental: ICU Exposed to Day lightExperimental Treatment1 Intervention
Patients undergoing trauma or elective surgery with ICU admission: Light therapy will consist of 30 minutes intense light each morning for 5-10 days. Blood will be drawn before sunrise and after light therapy. Light therapy will be performed by a study nurse to ensure proper use. In addition, endothelial function and activity will be measured using the noninvasive Endo-pat and ActiWatch device. The patient will need to keep the box as close as possible to their eyes and not walk away during the treatment period. This will be facilities by a study nurse.
Group II: Experimental: Exposed to Day lightExperimental Treatment1 Intervention
Patients undergoing primary sternotomy cardiac surgery: Patients will be enrolled 10 to 1 days prior to surgery and will receive an intense (bright light, Square One Wake Up Light NatureBright 10,000 LUX) box. The patient will start using the light box prior to surgery every morning from 8.30 to 9.00 AM. Blood /buccal swabs will be collected on the day of enrollment (10 to 1 days prior to surgery) between 7 and 10 AM without any light therapy and on the day of surgery between 7 and 10 AM before anesthesia induction after one week of light therapy.
Group III: Sham Comparator: Exposed to Room lightPlacebo Group1 Intervention
Patients undergoing primary sternotomy cardiac surgery: Patients will be enrolled 10 to 1 days prior to surgery and will receive a placebo/control device (dim/night light box). The patient will start using the light box 7 days prior to surgery every morning from 8.30 to 9.00 AM. Blood /buccal swabs will be collected on the day of enrollment (10 to 1 days prior to surgery) between 7 and 10 AM without any light therapy and on the day of surgery between 7 and 10 AM before anesthesia induction after one week of placebo therapy.
Group IV: Sham Comparator: ICU Exposed to Room lightPlacebo Group1 Intervention
Patients undergoing trauma or elective surgery with ICU admission: Light therapy will consist of 30 minutes using a placebo/control device (dim/night light box) each morning for 5-10 days. Blood will be drawn before sunrise and after light therapy. Light therapy will be performed by a study nurse to ensure proper use. In addition, endothelial function and activity will be measured using the noninvasive Endo-pat and ActiWatch device.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is the participant capacity of this research endeavor?

"Affirmative. According to information published on clinicaltrials.gov, this investigation is still recruiting patients which began being sought after the 12th of July 2019 and was most recently updated on the 2nd of May 2022. The research team needs approximately 70 participants from one location for the study"

Answered by AI

Is enrollment open to participants of any age below seventy-five?

"This experiment permits entry from those aged 18 to 90. 63 clinical trials are available for youth, while 812 are open to the elderly population."

Answered by AI

Are any more participants being welcomed into this experiment?

"That is correct. Per the information posted on clinicaltrials.gov, this trial is currently recruiting patients and was first announced on July 12th 2019 before being updated lastly on May 2nd 2022. The study needs 70 participants from a single medical centre in order to proceed."

Answered by AI

Could I potentially partake in this clinical experiment?

"This research is recruiting 70 candidiates, aged between 18 and 90, who have a diagnosis of myocardial infarction. Applicants must satisfy the following requirements: undergoing primary sternotomy cardiac surgery; being in sinus rhythm during their procedure; and falling within the specified age bracket."
