NCT ID: NCT03722979

Basic Information

• Recruitment Status: COMPLETED

• Total Enrollment: 53 participants

Brief Summary

The links between systemic inflammation, endothelial dysfunction and endoplasmic reticulum (ER) stress in pre-clinical models make it an interesting potential therapeutic target, but there are no data describing SRE during severe inflammation in humans .

For an approach to the study of SRE in humans in a situation of systemic inflammation, the analysis of patients benefiting from an extra-corporeal circulation for a programmed cardiac surgery would allow a study under well described conditions of inflammation, standardized, with the possibility for each patient to be his own witness. Compared to a situation of secondary inflammation (sepsis, acute pancreatitis, trauma ...) the analysis of the patients under CEC allows more precise description of the kinetics of the activation of the SRE because the beginning of the inflammatory mechanism is known with precision.

Eligibility Criteria

Inclusion Criteria

• Major patient (age ≥ 18 years)
• Patient undergoing cardiac surgery under extracorporeal circulation (duration of planned CEC > 1h)
• Informed person, having read and signed his consent preoperatively no later than the day before the procedure.

• Patient with surgery under "mini-CEC"
• Patient with simple aortic valve replacement or single / double coronary artery bypass (CEC duration typically <1h)
• Patient with chronic autoimmune inflammatory disease, eg lupus, rheumatoid arthritis, inflammatory bowel disease ...
• Patient with progressive neoplastic disease
• Patient with underlying heart disease with left ventricular ejection fraction <30%
• Pregnant or lactating woman
• Person deprived of liberty by an administrative or judicial decision or protected major subject (under tutorship or curatorship)
• Patient participating in another interventional clinical trial

• Minimum Eligible Age: 18 Years
